 For Windows targets, “Build Tools for Visual Studio 2022” (or a higher edition of Visual Studio) and the “Desktop development with C++” workflow must be installed. For Windows ARM64 targets, the “VS 2022 C++ ARM64 build tools” and "C++ Clang Compiler for Windows" components must be installed. And make sure `clang` can be found in the path by adding `C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\Llvm\x64\bin` for example in the environment variable `Path`.

-#### Using Nix

 pnpm tauri dev
-# or start development for the Web app
-pnpm dev-web
-# preview with OpenNext build for the Web app
-pnpm preview
 ```

-#### Android
-
-The following must be run once before running the Android app. Note that this is done automatically if using the nix Android devshell:
-
-```bash
-rm apps/readest-app/src-tauri/gen/android
-pnpm tauri android init
-pnpm tauri icon ../../data/icons/readest-book.png
-git checkout apps/readest-app/src-tauri/gen/android
-```
-
-To run the Android app:
-
-```bash
-pnpm tauri android dev
-# or if you want to dev on a real device
-pnpm tauri android dev --host
-```
-
-#### iOS
-
-```bash
-# Set up the iOS environment (run once)
-pnpm tauri ios init
-pnpm tauri icon ../../data/icons/readest-book.png

 📖 **[https://readest.com/docs][link-docs]**

-## Building from Source
+## Requirements

-To build Readest from the latest commit, see [Getting Started](./CONTRIBUTING.md#getting-started).
+- **Node.js** and **pnpm** for Next.js development
+- **Rust** and **Cargo** for Tauri development
+
+For the best experience to build Readest for yourself, use a recent version of Node.js and Rust. Refer to the [Tauri documentation](https://v2.tauri.app/start/prerequisites/) for details on setting up the development environment prerequisites on different platforms.
+
+```bash
+nvm install v24
+nvm use v24
+npm install -g pnpm
+rustup update
+```
+
+## Getting Started
+
+To get started with Readest, follow these steps to clone and build the project.
+
+### 1. Clone the Repository
+
+```bash
+git clone https://github.com/readest/readest.git
+cd readest
+```
+
+### 2. Install Dependencies
+
+```bash
+# might need to rerun this when code is updated
+git submodule update --init --recursive
+pnpm install
+# copy vendors dist libs to public directory
+pnpm --filter @readest/readest-app setup-vendors
+```
+
+### 3. Verify Dependencies Installation
+
+To confirm that all dependencies are correctly installed, run the following command:
+
+```bash
+pnpm tauri info
+```
+
+This command will display information about the installed Tauri dependencies and configuration on your platform. Note that the output may vary depending on the operating system and environment setup. Please review the output specific to your platform for any potential issues.
+
+For Windows targets, “Build Tools for Visual Studio 2022” (or a higher edition of Visual Studio) and the “Desktop development with C++” workflow must be installed. For Windows ARM64 targets, the “VS 2022 C++ ARM64 build tools” and "C++ Clang Compiler for Windows" components must be installed. And make sure `clang` can be found in the path by adding `C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\Llvm\x64\bin` for example in the environment variable `Path`.
+
+### 4. Build for Development
+
+```bash
+# Start development for the Tauri app
+pnpm tauri dev
+# or start development for the Web app
+pnpm dev-web
+# preview with OpenNext build for the Web app
+pnpm preview
+```
+
+For Android:
+
+```bash
+# Initialize the Android environment (run once)
+rm apps/readest-app/src-tauri/gen/android
+pnpm tauri android init
+pnpm tauri icon ../../data/icons/readest-book.png
+git checkout apps/readest-app/src-tauri/gen/android
+
+pnpm tauri android dev
+# or if you want to dev on a real device
+pnpm tauri android dev --host
+```
+
+For iOS:
+
+```bash
+# Set up the iOS environment (run once)
+pnpm tauri ios init
+pnpm tauri icon ../../data/icons/readest-book.png
+
+pnpm tauri ios dev
+# or if you want to dev on a real device
+pnpm tauri ios dev --host
+```
+
+### 5. Build for Production
+
+```bash
+pnpm tauri build
+pnpm tauri android build
+pnpm tauri ios build
+```
+
+Please refer to our release script if you experience any issues:
+https://github.com/readest/readest/blob/main/.github/workflows/release.yml
+
+### 6. Setup dev environment with Nix
+
+If you have Nix installed, you can leverage flake to enter a development shell
+with all the necessary dependencies:
+
+```bash
+nix develop ./ops  # enter a dev shell for the web app
+nix develop ./ops#ios # enter a dev shell for the ios app
+nix develop ./ops#android # enter a dev shell for the android app
+```
+
+### 7. More information
+
+Please check the [wiki][link-gh-wiki] of this project for more information on development.

+- [download_file scope Android regression](download-file-scope-android-regression.md) — #4639 strict `is_allowed` broke ALL Android downloads to app data dir (covers/dicts/books); `app.fs_scope()` lacks command-scoped capability globs; fix = `app.path()` base-dir membership. On-device CDP verify recipe + raw-invoke Channel trick
+- [Security advisories 2026-06](security-advisories-web-2026-06.md) — all 4 GHSA fixed in PR #4638 (web: A OPDS-proxy SSRF + canonical `isBlockedHost` in network.ts + `isLanAddress` merge, B storage `isSafeObjectKeyName`, D Stripe `metadata.userId` ownership) + PR #4639 (native C: `transfer_file.rs` fs_scope guard). OPDS proxy can't require auth (`<img>` usage); strict `is_allowed` for C; shared-target worktree build-cache pollution gotcha
+
+## Paginator Scroll Knowledge
+- [Issue #4112 scroll-anchoring](issue-4112-scroll-anchoring.md) — RESOLVED (PR #4349). Scroll-anchoring suppressed at scrollTop 0 when prepending a section in scrolled mode; fix patterns (prepend compensation, eager backward preload, no-blank nav) + test & dev-server gotchas
+- [Reading ruler line/column-aware](reading-ruler-line-aware.md) — ruler snaps to real lines; multi-column band spans one column; Range.getClientRects() returns tall block boxes that must be dropped; iframe frame-offset mapping; synthetic-key throttling
+- [TOC expand + auto-scroll](toc-expand-and-autoscroll.md) — #4059 collapse-by-default policy in `tocTree.ts`; pinned-sidebar mounts before progress → dynamic expansion breaks scroll-to-current via (1) spurious onScroll clearing pending and (2) Virtuoso scrollToIndex landing short after row growth (re-assert on rAF)
+- [BooknoteView auto-scroll (#4352)](booknote-view-autoscroll-4352.md) — virtualizing the annotation/bookmark list dropped auto-scroll-to-nearest; two paths (reload: OverlayScrollbars resets scrollTop → re-apply in `initialized` via ref; tab-switch: synchronous scrollToIndex on fresh-mounted list wedges Virtuoso → use `initialTopMostItemIndex` + skip-gate). Mirrors TOCView. Includes dev-server/Fast-Refresh/screenshot-vs-DOM verification gotchas
+- [TOC current-position row](toc-current-position-row.md) — synthetic "Current position" row (open-book icon + live `progress.page`) injected one level deeper under the active TOC item via `buildTOCDisplayItems` in `TOCItem.tsx`. INVARIANT: insert AFTER the active item so its `flatItems` index stays valid for the auto-scroll effects
+- [Swipe page-turn bg flash](paginator-swipe-bg-flash.md) — white↔black flash on swipe+animation only; `#background` was static screen-space and didn't track content during drag/snap; fix = sliding per-view full-bleed segments (`computeBackgroundSegments`) rebuilt on scroll + per-rAF synced to the view transform during snap
+- [Duokan fullscreen cover hidden in scroll mode](duokan-fullscreen-cover-scroll.md) — #4379 `data-duokan-page-fullscreen` cover pinned `position:absolute height:100%` collapses against auto-height scroll container; gate fullscreen on `this.#column` + reset stale absolute props on toggle (`setImageSize` in paginator.js)
+- [Paginated texture occlusion](paginated-texture-occlusion-4399.md) — #4399 host `.foliate-viewer::before` texture absent in paginated (shown in scrolled); opaque `#background` container (`= fallbackBg`) from the swipe-flash fix occludes it; shared `textureAwareBackground` helper + `hasTexture ? '' : fallbackBg` container
+- [Dark-mode texture occluded by body bg (#4446)](dark-mode-texture-body-bg-4446.md) — RESOLVED (PR #4564): `body.theme-dark{bg !important}` from #4392 (v0.11.4, NOT foliate-js) painted iframe bodies opaque dark → occluded host texture + poisoned `docBackground` capture → opaque segments/view bgs; fix = `transparent !important` UNCONDITIONALLY (texture-gating would go stale: capture is once-per-section-load); CDP gotchas = patch ALL multiview iframes, stale preload views survive navigation ±2, load-listener sees exact capture-time state
+- [Background overflows column (#4394, PR #4429)](paginator-gutter-bleed-asymmetry-4394.md) — paginated page bg stretched into the outer `--_outer-min` gutter → mixed cover/title 2-up spread shifted off-centre (~250px at 1920px). KEEP the grid (`--_outer-min` keeps margins symmetric); fix = clamp `computeBackgroundSegments` to `[containerStart,containerEnd]` (Math.max/Math.min) so bg stays in its column. 2 wrong tries first (bleed-gating, "page shouldn't be yellow"); foliate submodule needs dev-server RESTART to pick up edits
+- [Inline-block column overflow](inline-block-column-overflow.md) — chapter skips to "Reference materials", clipping a large middle; EPUB wraps body in `display:inline-block` div → atomic-inline box can't fragment across columns → vertical overflow clipped (scrollHeight≫clientHeight). Fix = paginator `#demoteUnfragmentableBoxes` in `columnize` (col-mode, over-tall atomic-inline→fragmentable block). Renders via goTo/next but pages unreachable; scrolled mode unaffected

+- [KOSync CFI spine resolution](kosync-cfi-spine-resolution.md) — convert via the CFI's own spine (`getXPointerFromCFI`/`getCFIFromXPointer`), never `new XCFI(primaryDoc, primaryIndex)`; primaryIndex lags during scroll → spine-mismatch throw
+- [Empty-start CFI sync bug](empty-start-cfi-sync.md) — `epubcfi(/6/24!/4,,/20/1:58)` (empty-start range) from the cfi-inert skip-link transitional window; jumps to wrong section end; `isMalformedLocationCfi` → discard the synced value in `useProgressSync` (NOT the local open path); foliate fix doesn't repair already-synced values
+- [Custom fonts disappear on cloud sync (#4410)](custom-fonts-reincarnation-4410.md) — CRDT remove-wins: re-import-after-delete needs a `reincarnation` token or the pull re-applies the tombstone; `addFont`/`addTexture` minted none; fix mirrors dictionary (both cases) + OPDS token style; coverage matrix per kind
+- [koplugin note deletion sync](koplugin-note-deletion-sync.md) — koplugin push only walked LIVE annotations so deletions never reached the server; fix = `recordDeletion` persists a `deletedAt` tombstone to `doc_settings.readest_sync.deleted_notes`, `push` folds+clears them; deletion signal in `onAnnotationsModified` is `items.index_modified < 0`
+- [koplugin stats sync (#4666)](koplugin-stats-sync.md) — reading-stats sync (pull on open / push on close, whole statistics.sqlite3 delta, cursor-based); 3-bug chain: plain-table-not-LuaSettings `settings:readSetting` crash; missing required books/notes/configs; statBooks/statPages need `optional_params` (Spore expected=required∪optional, `payload`≠accepted); large-backlog UI-stall + silent-retry risk unfixed

On-device CDP PUSH_SENT-vs-RETURNED proof recipe

+## Testing
+- [Nightly updater Android E2E](nightly-updater-android-e2e.md) — real Xiaomi/HyperOS test of #4577 self-updater; `pnpm dev-android` (--features devtools) for CDP, raw-socket CDP discovery, nightly>stable comparator, MIUI 单次安装授权 install gates
+- [Android CDP e2e lane](android-cdp-e2e-lane.md) — `pnpm test:android`: adb+CDP drives the installed app on device/emulator; discover-don't-assume targeting, injected hyphenation, MediaStore VIEW transient open (canonical `_data` path gotcha), per-section frame restore; CI workflow with KVM emulator + debug x86_64 APK (no signing secrets)
+- [CDP Android WebView profiling](cdp-android-webview-profiling.md) — drive the on-device Readest WebView via adb+CDP to run JS probes/benchmarks inside the live app (no rebuild); gotchas: locked device freezes fetch (not invoke), visible:false throttles setTimeout, `__TAURI_INTERNALS__.convertFileSrc/invoke` always present, books in internal `/data/user/0/...`, fs `read{rid,len}` last-8-bytes=nread, `fs|close` not ACL-allowed, curl mishandles WebView HTTP framing
+- [Tauri Rust↔JS parser parity tests](tauri-parser-parity-tests.md) — #4369 native Rust EPUB/MOBI parser; how to cross-check vs foliate-js in the `.tauri.test.ts` WebView suite (CWD disk path for Rust, Vite URL for JS, normalizer-based compare, cover presence-only, desc whitespace-collapse); the `dcterms:modified`→`published` divergence fix
+- [TTS browser e2e harness](tts-browser-e2e-harness.md) — faithful auto-advance test (real `<foliate-view>` + real `useTTSControl` + mock ONLY the 3 client modules; mock `speak()` yields `end` to drive the real `forward()` walk); seed readerStore/bookDataStore + `settings.globalViewSettings` (else `getMergedRules` crash stops TTS); reproduce FoliateViewer relocate→setProgress; sample-alice Ch4=section 6/Ch5=section 7; assert badge `false` BEFORE tts-stop
+- [TTS sync chrome verification](tts-sync-chrome-verification.md) — Edge TTS WORKS in claude-in-chrome (WebSpeech errors there with `InvalidStateError`); use an Edge voice to verify TTS-driven features live (RSVP followed at ~171 wpm). Synthetic-CFI debug recipe (expose controller, `syncToCfi(view.getCFI(docIndex, word.range))`). Exposed the #3235 cross-realm `instanceof Range` bug (frozen RSVP/paragraph follow) → `isRangeLike()` duck-type fix
+- [TTS sync paragraph+RSVP (#3235, PR #4576)](tts-sync-paragraph-rsvp-3235.md) — TTS-is-clock follow: canonical `tts-position{cfi,kind:word|sentence,sectionIndex,sequence}`; in-mode 🔊 audio toggle (`build{Paragraph,Rsvp}TtsSpeakDetail`, live-range gate); **current word/sentence highlight painted on the overlay CLONE via CSS Custom Highlight API** (no DOM mutation, spans inline; offsets relative to para-start map 1:1 to clone, `getTextSubRange` reuse, index-tagged vs stale); kind-gating `decideParagraphTtsHighlight` (Edge word wins, skip coarse sentence); `::highlight()` from `ttsHighlightOptions`
+
+## Build & Vendoring
+- [fastlane Apple App Store submission](fastlane-apple-appstore-submission.md) — `release_ios`/`release_macos` lanes (App Store review + TestFlight on the altool-uploaded build); gotchas = Tauri auto-notarizes if `APPLE_API_KEY_PATH` is in the macOS build env (keep it OUT, derive from key id), fastlane runs lanes from `./fastlane` so anchor paths via `repo_path`, npm-dotenv-cli vs Ruby-gem shadowing + `cd ../..`
+- [Turbopack build-cache OOM + gated Docker standalone (#4619)](turbopack-build-cache-oom-docker-standalone.md) — interrupted-build partial `turbopackFileSystemCacheForBuild` cache → 42 workers/18GB-swap freeze (clean build=~6.5GB); disabled the flag; `output:'standalone'` gated on `BUILD_STANDALONE` (Docker-only); tauri CI uses `next dev` (config-independent)
+- [Deps/security override workflow](deps-security-overrides-workflow.md) — fix transitive npm Dependabot alerts: main monorepo overrides live in `pnpm-workspace.yaml` (NOT root package.json); `packages/tauri-plugins` is a SEPARATE submodule project w/ own lockfile + `minimumReleaseAge` (main workspace has no age gate); bound 0.x overrides like `vite`; verify via test+lint+build-web. PR #4618 (esbuild 0.28.1, vitest 4.1.9)
+- [R2 rclone CreateBucket 403 (#4588)](r2-rclone-createbucket-403.md) — single-file `rclone copyto`/`moveto` probes CreateBucket → 403 on object-scoped R2 token; use a directory `rclone copy` (or `no_check_bucket=true`); broke nightly assemble, not the release flow
+- [Deploy workers.dev SNI-block + proxy](deploy-workers-dev-sni-proxy.md) — pnpm deploy crash (CN): workers.dev SNI-blocked (DoH useless), R2 populate WS hangs even via proxy; shipped fix = `dangerous.disableIncrementalCache:true` in open-next.config (stock deploy skips populate; readest has no ISR so runtime no-op)
+- [pdfjs vendor wasm decoders](pdfjs-vendor-wasm-decoders.md) — scanned PDFs blank in CI build only (0.11.2 regression); pdfjs 5.7.x moved JBIG2 to `jbig2.wasm`, `copy-pdfjs-wasm` allow-list dropped it; `cpx` no-errors on empty glob; local stale `public/vendor` (gitignored, not refreshed by `tauri build`) masked it; fix = copy `wasm/*`

+- [Android hyphen selection bounds (#1553)](android-hyphen-selection-bounds-1553.md) — Blink paints the start handle on the paragraph's LAST hyphen when a touch selection starts at the first word of a hyphenated paragraph (`ComputePaintingSelectionStateForCursor` lacks the generated-text offset remap, hyphen offsets {0,1}); drag-extend re-anchors base there. Fix = repair jumped anchor + suppress handles (empty-commit needs one painted frame) + `SelectionRangeEditor` custom handles; multicol NOT required; desktop/iOS unaffected
+- [Android NativeFile vs RemoteFile I/O](android-nativefile-remotefile-io.md) — why NativeFile is slow (4-IPC/chunk + bridge serialization, tauri#9190); RemoteFile CANNOT replace it on Android (asset-protocol Range broken: start>0 → "Failed to fetch", start-0 capped at 1,024,000; plain no-Range fetch returns full file at 281 MB/s); measured 44/100/281 MB/s; speedups = handle-reuse (2.3×), whole-file asset loader (6.3×), or fix wry upstream. Verified live via CDP.
+- [Window-state sanitizer (#4398)](window-state-sanitize-4398.md) — Windows launch crash (WebView2 0x80070057) from invalid `.window-state.json` (`-32000` minimized sentinel / `0×0`); our plugin already has upstream #253 fix so bad files are stale; defense-in-depth `window-state-sanitizer` plugin registered BEFORE window-state (plugin init = registration order); coord threshold `-16000` (~halfway to the -32000 sentinel; real desktops sit a few thousand px off origin) keeps multi-monitor negatives
+- [Android Open-with intent flow (#4521)](android-open-with-intent-flow.md) — "Open with"/"Send to" pipeline: `NativeBridgePlugin.kt::handleIntent` → `shared-intent` → `useAppUrlIngress` → `useOpenWithBooks` (VIEW=transient→reader, SEND=library+upload). Telegram fails where file-manager works on TWO axes: cold-start delivery (fixed by #4527, on dev NOT released v0.11.4) + foreign-private-file read (Telegram FileProvider non-persistable grant vs shared-storage FUSE real-path). adb MediaStore VIEW repro tests pipeline but CANNOT reproduce the read axis (MANAGE_EXTERNAL_STORAGE bypasses grant)
+- [Dict lookup → OEM browser hijack (#4559)](dict-lookup-browser-hijack-4559.md) — VIVO system-dict lookup opened the browser not Eudic. PRIMARY: no `<queries>` for `ACTION_PROCESS_TEXT` under targetSdk36 → dictionary apps invisible, only auto-visible browser returned (fix = add `<queries>` to plugin manifest). SECONDARY: browser registers PROCESS_TEXT + is default → filter browsers in pure `decideLookupDispatch` (explicit/chooser/unavailable). Remember-the-pick via `IntentSender`+`EXTRA_CHOSEN_COMPONENT`→`LookupChoiceReceiver`→SharedPreferences (`ACTION_CHOOSER` has no native Always); reset row in `CustomDictionaries.tsx`
+- [Android sideload same versionCode](android-sideload-same-versioncode.md) — sideloaded APK reinstall allows EQUAL versionCode (only strictly-lower blocked); Play Store's increment rule does NOT apply to sideload. Nightly APKs share base versionCode and still install. Corrects a plausible-but-wrong review claim
+- [Large-PDF OOM range flood (#3470)](pdf-oom-range-flood-3470.md) — 50MB+ PDF import/open crash = foliate makePDF firing ALL pdf.js range reads un-awaited (753 concurrent fetch→shouldInterceptRequest→Java byte[] → 512MB heap OOM), NOT whole-file load; official viewer survives via browser ~6-conn/host cap; fix = MAX_CONCURRENT_RANGES=6 queue in makePDF; on-device CDP recipe; Xiaomi13/WV147 won't OOM but flood 753→6 verified
+
+## Feature Notes
+- [Save image to gallery (Android, #4680)](save-image-to-gallery-android.md) — image-viewer Save button → MediaStore on Android (share sheet can't save-to-file: ACTION_SEND has no file-manager target); sharekit 0-byte self-copy bug (Temp==cacheDir); tsgo misses abstract-class conformance (real tsc catches); on-device CDP verify recipe
+- [Webtoon Mode (#3647)](webtoon-mode-3647.md) — seamless no-gap scrolled reading for image books (PRs #4662 + foliate-js#30); fixed-layout scroll mode is fit-width by construction (ignores `zoom`, only `scale-factor`); `scroll-gap` attr→`--scroll-page-gap` var; clear-on-leave in BOTH ViewMenu effect AND Shift+J; worktree submodule has local-path origin (push SHA direct to fork)
+- [Biometric app-lock (#4645)](biometric-app-lock-4645.md) — fingerprint/Face ID startup unlock layered over PIN (mobile); gate must read flag from `appLockStore` not un-seeded `settingsStore` (race); `tauri-plugin-biometric` is `#![cfg(mobile)]` (desktop clippy skips it; pin in root Cargo.lock); scope i18n manually (en unscanned, full extract churns drift)
+- [Tap to open image/table (#4600)](tap-to-open-image-table-4600.md) — single-tap opens gallery/table-zoom in **reflowable** EPUBs (long-press unchanged); `iframe-long-press` message renamed to `iframe-open-media`, hook `useLongPressEvent`→`useOpenMediaEvent`; shared `detectMediaTarget`; `handleClick` got `isFixedLayout`
+- [#4584 tap-death investigation](issue-4584-tap-death-investigation.md) — UNFIXED; `isPopuped` self-heals (RED HERRING, don't "fix" it); likely WebView-148-specific (emulator=133 can't repro); Android emulator/CDP gesture-verification gotchas (swiftshader ANR=artifact, CDP can't native-select, screenX=0)
+- [Dictionary lemmatization (#4574)](dict-lemmatization-4574.md) — inflected selections (`ran`/`mice`/`analyses`) resolve to base headwords (`run`/`mouse`/`analysis`) in dicts that store only lemmas (ODE). Pluggable `lemmatize/` registry (default English, explicit non-English no-op), English rules+irregulars, appended to tail of `buildLookupCandidates` so exact match wins; over-generate + dict-validates; `-ses→-sis` ordered before `-es`
+- [Word Lens inline gloss (feat/word-wise)](wordlens-feature.md) — Kindle-style native-language hint above hard words; CFI-safe via `<ruby cfi-skip>…<rt cfi-inert>` (epubcfi hoist+merge, NOT just tree-walk); TTS/search isolation (tags:['rt'] + rangeTextExcludingInert + search attributes:['cfi-inert']); gloss data = curated starters, full asset built by `build-wordlens-data.mjs` (ECDICT/CC-CEDICT+HSK)
+- [iOS instant-dict double popup](ios-instant-dict-double-popup.md) — iOS emits multiple `selectionchange`/long-press → instant sys-dict fired 2-3×; deferredAction `fired` once-per-gesture latch + `beginGesture`; tap-to-deselect re-fire fixed by `isLongPressHold` 300ms gate (!isAndroid); Word Lens `wantWordLensDict` now routes via `handleDictionary` to honor system dict
+- [Edge TTS word highlighting (#4017, PR #4566)](edge-tts-word-highlighting-4017.md) — keep sentence marks, add word highlight via `audio.metadata` WordBoundary (verbatim input span, 100-ns ticks) synced to `audio.currentTime` by rAF; readaloud endpoint gates on UA (Edg, non-headless) NOT Origin; fixed browser `new WebSocket(url,{headers})` SyntaxError (wss never worked on web); overlay = `<path>` in FOLIATE-PAGINATOR shadow root; dev-web verify recipe (browse --proxy + UA spoof, never Origin header)
+- [Reference Pages (#672+#4542, PR #4549)](reference-pages-672-4542.md) — 'reference' progressStyle from foliate `pageItem`/`book.pageList` (numeric-max total rule, roman-tail safe); per-book `referencePageCount` via skipGlobal save; verification EPUBs + dev-web synthetic drag-drop import trick; locale-tail rebase-conflict recipe (checkout --ours → re-extract → re-translate)
+- [OPDS Firefox strict-XML parse (#4479)](opds-firefox-strict-xml-4479.md) — MEK feed has junk after `</feed>`; Firefox DOMParser → `<parsererror>` (silent back-nav), Chrome lenient; `parseOPDSXML` slices root start→last close tag; jsdom mirrors Firefox; wired into page.tsx + validateOPDSURL + feedChecker (latter also #4181 `looksLikeXMLContent` swap)
+- [OPDS 2.0 JSON search greyed out (#4502)](opds2-json-search-4502.md) — `isSearchLink` ignored templated `application/opds+json` links → `hasSearch` false → disabled navbar input; add `MIME.OPDS2`+`templated`, `expandOPDSSearchTemplate` (foliate `uri-template.js`), handleSearch OPDS2 branch. Gotcha: `resolveURL` mangles `{?query}` braces — expand template BEFORE resolving
+- [OPDS HTML description (#4503)](opds-html-description-4503.md) — detail-view descriptions showed raw `<p>`/`&quot;` tags; aggregator double-escapes `type="text"` summary + `PublicationView` dumped it into unsanitized `dangerouslySetInnerHTML`; fix = `getOPDSDescriptionHtml` (decode-one-level-iff-fully-escaped, then `sanitizeHtml`)
+- [Manage Cache + iOS container layout](manage-cache-ios-layout.md) — `'Cache'` base = `Library/Caches/<bundle>` only (not all of Caches); iOS `Documents/Inbox` cleared too; WebKit cache + tmp out of reach; never touch App Support
+- [D-pad Navigation](dpad-navigation.md) — Android TV remote / keyboard arrow navigation design, key files, and pitfalls
+- [Cloudflare Workers WebSocket](cloudflare-workers-websocket.md) — use fetch() Upgrade pattern (not `ws` npm); CF delivers binary frames as Blob (must serialize async decodes)
+- [Share-a-Book Feature (in progress)](share-feature.md) — locked decisions for the /s/{token} share-link feature; plan at ~/.claude/plans/ok-we-will-learn-cosmic-acorn.md
+- [readest.koplugin i18n](koplugin-i18n.md) — gettext loader at `apps/readest.koplugin/i18n.lua`, `.po` catalog at `locales/<i18next-code>/translation.po`, extract/apply scripts in `scripts/`
+- [koplugin cover upload](koplugin-cover-upload.md) — #4374 uploadBook only shipped cached cloud covers; local-origin books uploaded blank. Fix = `extractLocalCover` via `FileManagerBookInfo:getCoverImage(nil, file)` → `writeToFile(path,"png")`. KOReader checkout at `/Users/chrox/dev/koreader`
+
+## Feedback
+- [Commit messages English-only](feedback-commit-message-english-only.md) — commit messages + PR titles must be English only (no CJK glyphs, no em/en dashes); keep CJK examples/screenshots in the PR body, code, and tests. From PR #4660
+
+## Patterns
+- [Virtuoso + OverlayScrollbars](virtuoso_overlayscrollbars.md) — useOverlayScrollbars hook integration for overlay scrollbars on mobile webviews
+- [Design system → DESIGN.md](feedback_design_system_doc.md) — codify recurring UI/UX rules in `apps/readest-app/DESIGN.md`; never `pl/pr/ml/mr/text-left/text-right` (RTL); §5 boxed list anatomy has uniform `min-h-14` rows and chromeless controls
+
+## Reader UI Fixes
+- [RSVP control bar overlap = REVERT](rsvp-control-bar-overlap-revert.md) — mobile RSVP TTS+settings overlapping transport was a REGRESSION: #4585 fixed it (in-flow `justify-between md:justify-center`), stale-branch #4589 (Word Wise) squash-reverted the whole fix incl. its guard test; re-fixed + on-device CDP recipe (Shift+V to enter RSVP, live-DOM preview)
+- [Overlay z-index scale](zindex-overlay-scale.md) — compact global scale (RSVP 100/101, Settings 110, ModalPortal/CmdPalette 120, toast 130, app-lock 200) replacing insane 10000s; Add-Catalog-behind-Settings was MOBILE-ONLY (desktop `.window-border` z-99 traps inline Settings; ModalPortal portals to body→wins); static invariant test `zIndexScale.test.ts`; on-device CDP verify via `pnpm dev-android` devtools build
+- [Search excerpt no context for styled words (#4594)](search-excerpt-context-4594.md) — RESOLVED (foliate-js#25 + readest#4631). italic/`<i>` word = own `strs[]` text node; `makeExcerpt` read context only WITHIN the node → empty pre/post; fix = `collectBefore/After` walk neighbour nodes (+2 latent multi-node match bugs: string-index `slice`, `start===end`)
+- [Global annotation page-turn lag (#4575)](global-annotation-pageturn-perf-4575.md) — highlighting recurring names = `global` highlights re-fanned-out (TreeWalker + getCFI/occurrence + SVG churn) EVERY page turn (~25-45ms desktop, ×mobile); fix = `WeakMap<Document,...>` memo in `globalAnnotations.ts` skips already-expanded sections; live-profiled via dev-web foliate-view; GBK-TXT synthetic-drop import recipe
+- [Overlayer splitRange by text nodes](overlayer-splitrange-textnodes.md) — highlight SVG missed bullet-list text when range also touched a `<p>`: `#splitRangeByParagraph`'s `'p,h1-h4'` selector dropped `li` (3rd whack-a-mole after f087826/920676b); fix = walk text nodes + `img,svg` in overlayer.js, never block-tag selectors; jsdom test stubs `Range.prototype.getClientRects`
+- [Android image callout freeze](android-image-callout-freeze.md) — long-press `<img>` fires WebView native callout that collides with app touch handlers → whole-app freeze; `-webkit-touch-callout: none` doesn't inherit so put `.no-context-menu` on an ancestor of the image (`.no-context-menu img` rule in globals.css); seen on book covers (#4345) + image preview/zoom (#4420, `ImageViewer.tsx`)
+- [ProgressBar focus-ring line (#4397)](progressbar-focus-ring-4397.md) — decorative `.progressinfo` footer was `tabIndex={-1}` → Android long-press focused it → stray content-width focus-ring line at the bottom every page; fix = drop tabIndex (role='presentation' must not be focusable); ffmpeg-the-video debugging + live-browser `:focus-visible` confirmation
+- [Table dark-mode tint regression (#4419)](table-dark-mode-tint-4419.md) — `blockquote, table *` color-mix tint in `getColorStyles` must stay gated on `overrideColor` (gate added #2377, removed #4055, re-broke → #4419); safe now that #4392 light-bg rewriters handle #4028 zebra legibility; SAME rule paints vertical-TOC `.space`/▉ spacer cells (▉ U+2589 = blank glyph, contours=0) → "spacing changes" symptom; both fixed by the gate
+- [Double-click-drag turns page (#4524)](dblclick-drag-pageturn-4524.md) — web double-click+drag selection also turned the page; 1st click's deferred single-click (250ms) fires mid-drag while 2nd-click button held; fix = `isMouseDown` flag in `iframeEventHandlers.ts` gates the deferred `postSingleClick`; synthetic-repro gotchas (shadow-DOM iframe walk, chained-repro timing pollution, reload to re-bind listeners)
+- [RSVP font face/family (#4519)](rsvp-font-settings-4519.md) — RSVP word was hardcoded `font-mono`; now mirrors the reader font via `getBaseFontFamily(viewSettings)` (new export in `style.ts`, shares `buildFontFamilyLists` with `getFontStyles`). Overlay renders in the TOP document (portal to body) where custom + basic Google fonts are mounted; known gap = built-in CJK web fonts only in top doc when `isCJKEnv()`
+- [RSVP RTL word display (#4630)](rsvp-rtl-word-display-4630.md) — Arabic/RTL word window showed separated, reversed letters: ORP focus-letter split slices words by char index (breaks shaping/order); fix = `isRTLText` → render RTL whole via the CJK `.rsvp-word-whole` branch with `dir=rtl`. Literal-RTL-char Edit pitfall → write regex with `\u` escapes
+- [Edge TTS word-highlight drift on middle sentences](tts-word-highlight-singletextnode-drift.md) — `rangeTextExcludingInert` TEXT_NODE fast path ignored range offsets → returned whole paragraph → word offsets drift (spoken "Those"→hl "if th"); only middle sentences of single-`<span>` paras (cac=TEXT_NODE); Edge-only; fix=slice [startOffset,endOffset]; added dev-only `[TTS] word-sync` log; select-word→popup-headphone repro
+- [TTS start-from-selection bugs](tts-start-from-selection.md) — foliate `from()` picked first mark at/after selection → started NEXT sentence for non-first words (fix=last mark at/before); + Annotator now `cloneRange()`+`view.deselect()` on TTS start so the word doesn't stay selected; jsdom needs `CSS.escape` polyfill (vitest.setup) since `from()` uses it
+- [Reuse TTS session on Paragraph/RSVP entry](tts-reuse-session-mode-entry.md) — modes only engaged following on a fresh `playing` event → entering with TTS already playing didn't sync. Fix = `TTSController.redispatchPosition()` + `useTTSControl` `tts-sync-request` replay (position-before-state) + per-mode engage-on-entry effect (following=true, reset lastSequenceSeen, dispatch request); RSVP paused branch also `setExternallyDriven(true)`. Paragraph live-verified ("Following audio" on entry)
+- [Footnote aside border line (#4438)](footnote-aside-namespace-order-4438.md) — v0.11.4 regression: stray horizontal line below footnote marker. #4383 inlined custom `@font-face` BEFORE the `@namespace epub` (which lived in `getPageLayoutStyles`), invalidating it per CSS spec → namespaced `aside[epub|type~="footnote"]{display:none}` dropped → book's `aside{border:3px double}` showed. Only with custom fonts loaded. Fix = hoist `@namespace` to front of `getStyles`. Repro needs XHTML (`epub:type` namespaced only in XML); Playwright `setContent` parses HTML and won't reproduce
+- [Scrolled-mode notch mask vs texture (#4486)](notch-mask-texture-4486.md) — top inset mask occluded the bg texture; full-cell + clip-path paint-box-matching for tile alignment; CDP-inject + MAE seam verification on device; adb taps in status-bar region eaten by SystemUI
+- [Paragraph-mode accidental exit + off-center bar (#4474)](paragraph-mode-accidental-exit-4474.md) — backdrop/center taps exited focus mode (stray "too high/low" taps); `ParagraphBar` only reshows on mousemove (no touch reshow) so can't just delete tap-exits → new `paragraph-show-controls` event reveals the bar instead. Also bar `absolute`→`fixed`: it centered on the gridcell which a pinned sidebar shifts right, while the paragraph centers on the `fixed inset-0` overlay/viewport
+- [Share intent + customizable toolbar (#4014)](annotation-share-toolbar-4014.md) — Share tool in the selection toolbar (sharekit gated mobile+macOS only re: #4343 Windows freeze; `canShareText`/`shareSelectedText` in dual-purpose `share.ts`) + drag-and-drop customizer sub-page; `annotationToolbarItems` view setting (Share hidden by default); pure helpers in `annotationToolbar.ts`

+- [Tauri menu append race (#4389)](tauri-menu-append-race-4389.md) — un-awaited `Menu.append()` (async IPC) in `BookshelfItem.tsx` → context-menu items shuffle order every open (native only, invisible in jsdom); fix = single `await Menu.new({ items })` of ordered `MenuItemOptions`; order/inclusion extracted to pure `getBookContextMenuItemIds` for unit testing
+- [TXT author recognition (#4390)](txt-author-recognition-4390.md) — 【】-titled Chinese web-novels show author missing/garbage; they're TXT→EPUB (title==full filename is the tell, check `txt.ts` not foliate-js); `extractTxtFilenameMetadata` only handled 《》 + greedy header capture grabbed metadata blobs; fix = `parseLabeledAuthor` for any filename + `isPlausibleAuthorName` guard
+- [TXT chapter measure-word false positives (#4658)](txt-chapter-measure-word-4658.md) — `第一封信`/`第四本书…` (量词 prose) detected as chapters; `createChapterRegexps('zh')` unit class split into strong `[章节回讲篇话]` (attached title OK) vs weak/量词 `[卷本册部封]` (title needs a separator or line end, never a bare noun)
+- [Cover stale until refresh (in-place mutation vs React.memo)](cover-stale-inplace-mutation-memo.md) — editing a book cover in details + Save left the library cover stale until reload; `handleUpdateMetadata` mutated `book` IN PLACE so memoized `<BookCover>`'s prev snapshot pointed at the same object → comparator saw no change → skip; fix = pure `getBookWithUpdatedMetadata` returns a NEW book object. Cloning in `updateBook` wouldn't help (original already mutated). Verified live on emulator via CDP fiber-store extraction (A: mutate→stale, B: new obj→updates)
+- [Series/author folder back no-op (#4437)](series-folder-back-noop-4437.md) — back arrow dead inside Series/Author folder after cold start; Next.js 16.2 static-export empty-search `router.replace` no-op (same as #3782/#3832); `GroupHeader.handleBack` missed the `group=''` workaround. CDP-verify gotcha: synthetic `el.click()` won't fire React onClick — use trusted `Input.dispatchMouseEvent`
+
+## Library Architecture
+- [Book action platform surfaces](book-actions-platform-surfaces.md) — library context menu is **Tauri-desktop-only** (`hasContextMenu` false on web + iOS/Android); cross-platform book actions go in `BookDetailView`'s icon row. #4543 Goodreads search added both surfaces + a built-in web-search provider for highlighted-text lookup
+
+## Architecture Notes
+- foliate-js is a git submodule at `packages/foliate-js/`
+- Multiview paginator: loads adjacent sections in background, multiple View/Overlayer instances per book
+- Style overrides: `getLayoutStyles()` (always), `getColorStyles()` (when overriding color)
+- `transformStylesheet()` does regex-based EPUB CSS rewriting at load time
+- TTS uses independent section tracking (`#ttsSectionIndex`) decoupled from view
+- Safe area insets flow: Native plugin -> useSafeAreaInsets hook -> component styles
+- Dropdown menus use `DropdownContext` (not blur-based) for screen reader compat
+- [Foliate touch-listener capture phase](foliate-touch-listener-capture-phase.md) — to suppress reader gestures from the app, use `{capture:true}`; the paginator registers bubble-phase doc listeners first (during `view.open()`)
+- [iframe cross-realm instanceof](iframe-cross-realm-instanceof.md) — app-bundle code (style.ts, iframeEventHandlers.ts) runs in top realm; `iframeEl instanceof Element` is ALWAYS false → guards silently drop all iframe elements (passes jsdom, dead in app). Duck-type `'closest' in target` instead. Bit PR #4391's touch routing + applyTableStyle dedupe
+
+## Workflow
+- [Test file filter](feedback_test_file_filter.md) — use `pnpm test <path>` without `--` to run a single file
+- [Always rebase before PR](feedback_pr_rebase.md) — rebase onto origin/main before creating PRs
+- [New branch per PR](feedback_pr_new_branch.md) — always create a fresh branch from main for each new PR/issue
+- [Upgrade gstack locally](feedback_gstack_upgrade.md) — always upgrade from the project's .claude/skills/gstack, not global
+- [No lookbehind regex](feedback_no_lookbehind_regex.md) — never use `(?<=)` or `(?<!)` in JS/TS; build check rejects them
+- [Use worktree](feedback_use_worktree.md) — never `git worktree add` directly; always `pnpm worktree:new` before PR review, issue fix, or feature work
+- [en/translation.json holds ONLY plural variants + proper nouns](feedback_en_plurals_manual.md) — non-plural strings stay out (defaultValue: key is the en source); plural strings (`_('...', { count })`) need hand-added `_one`/`_other` entries or the singular renders as "1 days"
+- [Never push on every change](feedback_dont_push_every_change.md) — hold pushes during active bug iteration; commit locally only until user confirms or work hits a clean done-state

-Android Auto TTS media session support (#3919) merged in PR#4907. CarPlay counterpart blocked on Apple entitlement.
-
-**Google Play rejection (2026-07-09):** the Android Auto review track rejected the release because the Auto TTS feature still has a bug (being fixed in a separate session). To unblock the resubmission, the Auto opt-in was removed from `src-tauri/gen/android/app/src/main/AndroidManifest.xml` in PR#5038 (MERGED 2026-07-09): the `<meta-data android:name="com.google.android.gms.car.application" android:resource="@xml/automotive_app_desc" />` entry inside `<application>`. The guard test `src/__tests__/android/android-auto-declarations.test.ts` now asserts the meta-data is ABSENT; flip those assertions back when re-enabling.
-
-**How to re-enable once the bug is fixed:** re-add that meta-data entry. The resource `res/xml/automotive_app_desc.xml` was intentionally left in place (unreferenced but harmless), and the `MediaBrowserService` intent-filter on `com.readest.native_tts.MediaPlaybackService` also stays — it's required for the phone lock-screen/background TTS media session ([[android-bg-tts-media-session-fix]]) and does not by itself trigger Play's Android Auto review; only the `com.google.android.gms.car.application` meta-data does.

-Branch `fix/android-bg-tts-media-session` (worktree `/Users/chrox/dev/readest-fix-android-bg-tts-media-session`), 2026-07-07. **PR readest/readest#4994 MERGED** (2026-07-07; worktree + local branch cleaned up. rebased onto origin/main; foliate-js submodule re-synced to f6dced2 after rebase per [[worktree-rebase-submodule-drift]]). 5 commits: 15817fc4b in-process IPC, 04e4b4fe6 duration scrubber+seek, 67c22b72b FGS hardening+diagnostic logs, 27e224bcc keepAppInForeground removal (the real fix), a8643ec12 Edge edge-fade click fix. Verified on-device (Xiaomi/MIUI/Android 15). Diagnostic Log.d traces left in 67c22b72b (offered to strip).
-
-**Regression (commit 1, `fix(android): keep background TTS media controls alive when backgrounded`):** after #4941 (session decoupling) + #4931 (Edge WebAudio engine), Android background TTS lost the lock-screen control and audio died when backgrounded. Logs: `Not allowed to start service Intent { act=UPDATE_PLAYBACK_STATE ... MediaPlaybackService }: app is in background`.
-
-Root cause: `NativeTTSPlugin.update_media_session_state`/`update_media_session_metadata` pushed updates to the already-running foreground service via `activity.startService(intent)`. Android 8+ (BSSR) rejects `Context.startService()` from the background unless an active foreground service exempts the app; each per-sentence update threw, so the FGS notification stopped refreshing (lock-screen control went stale) and the audio route was lost. **Fix pattern: never `startService()` to talk to a running service - call the live instance in-process.** `MediaPlaybackService` already had the pattern: static `@Volatile instance` + `requestDeactivation()` posting to it on the main thread. Added companion `pushMetadata`/`pushPlaybackState` (update statics, post to `instance` via `Handler(Looper.getMainLooper())`) + private instance `applyMetadata`/`applyPlaybackState`; removed the dead `UPDATE_METADATA`/`UPDATE_PLAYBACK_STATE` intent branches + the now-unused `serviceScope`/`kotlinx.coroutines.*`. `startForeground()` to *update* an already-foregrounded service is allowed from background (unlike `Context.startForegroundService()` to *start* one).
-
-Secondary: #4941 dropped the `keepAppInForeground`/notification titles from `TTSMediaBridge.bind()`'s `setActive({active:true})`. `keepAppInForeground` gated `requestPostNotificationPermission()` in `mediaSession.ts`, and it defaults false (`alwaysInForeground` in constants.ts), so POST_NOTIFICATIONS was never requested. Fix: `setActive` requests it on EVERY activation (no-op once decided), not gated on the setting - else the FGS media notification (= the lock-screen control) is silently suppressed on Android 13+.
-
-**Feature (commit 2, `feat(android): show section duration and enable seek on the TTS media session`):** user asked to show estimated section duration + seek from the media session. JS half was already there - `ttsMediaBridge.#updatePositionState` already sends `{playing, position, duration}` (ms) every mark, and `mediaSession.ts` already listens for a `media-session-seek` event -> `handlers['seekto']` -> `controller.seekToTime(pos/1000)`. Native side never used them. Added: `METADATA_KEY_DURATION` in the session metadata (Android reads scrubber length from METADATA, thumb from PlaybackState), `ACTION_SEEK_TO` in `setActions`, and `SessionCallback.onSeekTo(pos)` -> `pluginEventTrigger("media-session-seek", {position})` + optimistic thumb move. Bare play/pause updates omit position/duration, so `pushPlaybackState(playing, position: Long?, duration: Long?)` preserves last-known statics (else scrubber snaps to 0 on pause). **Section timeline is Edge/WebAudio ONLY** (`TTSController` comment "position/duration/seek (Edge client only)"; `getPlaybackInfo()` returns null for native TextToSpeech) - native TTS leaves duration 0 so no scrubber appears, which is correct.
-
-**On-device (Xiaomi/MIUI, targetSdk 36) round 1 FAILED - two findings:** (1) tested APK was STALE - logcat still showed `startService(act=UPDATE_METADATA/UPDATE_PLAYBACK_STATE)` which the fix removes, so the fix wasn't built in (likely built from main tree, not the worktree). (2) Deeper root cause the IPC fix does NOT touch: `W/ActivityManager: Stopping service due to app idle: ...MediaPlaybackService` = the service was NEVER promoted to a foreground service (FGS services aren't idle-stopped; readest uid never appears in FGS-type logs). Also MIUI hostile: uid 10186 (SecurityCenter) repeatedly sets readest `post_notification` appop to `ignore`; `Force stopping service`. Audio plays via WebView (`org.chromium.content.browser.AudioFocusDelegate` holds focus), and the service ExoPlayer also requests AUDIOFOCUS_GAIN - possible focus-steal conflict (unconfirmed).
-
-**Commit 3 (`fix(android): harden TTS foreground-service promotion + add diagnostics`):** `showNotification` now uses `ServiceCompat.startForeground(this, id, notif, ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PLAYBACK)` (explicit type, targetSdk 34+) wrapped in try/catch+Log. `setActive` (mediaSession.ts) decoupled: POST_NOTIFICATIONS request in its own try/catch so a throw/hang can't abort `set_media_session_active` (the FGS start). Trace logs added: `set_media_session_active: startForegroundService` (plugin), `activateSession (wasActive=)`, `startForeground ok`/`failed`. Next device run: build FROM the worktree + `adb uninstall com.bilingify.readest` first; set MIUI Autostart ON + battery No-restrictions + lock in recents; grep logcat for those tags to see where the FGS path breaks. If `startForeground ok` but audio still dies backgrounded -> WebAudio AudioContext suspension (test native voice: survives = confirms WebView issue).
-
-**ACTUAL ROOT CAUSE found round 3 (WebView console `[INFO:CONSOLE]` via `adb logcat` chromium tag):** `Failed to set media session active state: invalid args payload for command set_media_session_active: missing field keepAppInForeground`. The Rust `SetMediaSessionActiveRequest` (models.rs) had `keep_app_in_foreground: bool` as a REQUIRED serde field (all other fields `Option`); #4941's `ttsMediaBridge.bind()` sends `setActive({active:true})` without it, so **Tauri rejected the invoke at the serde layer before the command ran** -> `set_media_session_active` never executed -> FGS never started -> no notification + Android 15 `AS.AudioService: AudioHardening background playback would be muted` killed background audio. Every earlier fix (in-process IPC, FGS hardening, POST_NOTIFICATIONS decouple) was downstream of this and couldn't help because the command never ran. Diagnostic trap: native tags (MediaPlaybackService/NativeTTSPlugin) were absent from logcat because the service was never touched; the answer was only in the WebView JS console (grep logcat for `CONSOLE`). Commit 4 (`fix(android): drop required keepAppInForeground so the TTS service starts`, 27e224bcc): removed `keepAppInForeground` ENTIRELY (dead everywhere - no platform read it; FGS always starts, POST_NOTIFICATIONS now unconditional) from Rust/Kotlin/iOS/TS payloads per user request ("default true"). Follow-up commit 0b8843012 also removed the now-dead `alwaysInForeground` setting + its Android "Background Read Aloud" library-menu toggle (settings.ts/constants.ts/SettingsMenu.tsx + tests) and pruned the i18n key across 33 locales via `pnpm i18n:extract`. **Lesson: on a failed Tauri mobile command, capture the WebView console (logcat `CONSOLE` tag) FIRST - serde arg-rejection surfaces only there, not in native logs.**
-
-Verified: `pnpm test` (7022 pass), `pnpm lint` clean, `cargo check/fmt/clippy -p tauri-plugin-native-tts` clean. **Kotlin NOT compiled/device-verified** - worktree `src-tauri/gen/android` lacks `tauri.settings.gradle` so the plugin's `app.tauri.plugin.*` deps don't resolve standalone; needs `pnpm tauri android` on a real Android 13+/14 device (logcat: foreground -> background -> lock screen).

-Nightly `Android E2E (CDP)` failed every night from 2026-06-28 (first night after
-PR #4846 merged) with `timed out waiting for selection of "..." (last: null)` in
-`double-click.android.test.ts`. The test never passed on CI. Fixed 2026-07-04 —
-harness-only, no app code changed.
-
-**Two stacked root causes:**
-
-1. **PRIMARY — feature is opt-in on mobile.** `DEFAULT_MOBILE_VIEW_SETTINGS`
-   ships `disableDoubleClick: true` (double-click detection delays single-tap
-   page turns by the 250ms disambiguation window, so mobile opts out).
-   `handleClick` (iframeEventHandlers.ts) then posts `iframe-single-click`
-   IMMEDIATELY and never arms the double-click window — the #4846 double-tap
-   word selection is deliberately "gated by the user's double-click setting"
-   (Annotator comment). The e2e assumed default config → could never pass on a
-   fresh device. Diagnostic signature: `iframe-single-click` ~20ms after click
-   (window disabled) vs ~250ms after (window armed, no second click).
-2. **SECONDARY — adb double-tap can't hit the window.** The old helper ran
-   `input tap x y && input tap x y`; each `input` invocation spawns a fresh
-   app_process JVM (measured 0.9–1.05s each, 28s cold). Warm fast host ≈130ms
-   click gap (passes), loaded CI emulator >250ms (always fails).
-
-**Fix (all in `src/__tests__/android/`):**
- `reader.ts patchGlobalViewSettings(patch)` — force-stop app, read/patch
-  `settings.json` `globalViewSettings` via `adb shell run-as` (debug builds
-  only; file lives at the app data dir ROOT, not files/), write back via
-  base64 pipe, return previous values for restore in afterAll. Missing
-  settings.json is fine: `loadSettings` deep-merges partial file over defaults.
- `cdp.ts CdpPage.doubleTap(cssX, cssY)` — ONE
-  `Input.synthesizeTapGesture {tapCount: 2, duration: 20, gestureSourceType: 'touch'}`;
-  renderer-internal timing gives ~200ms click gap on a busy emulator. TWO
-  sequential synthesizeTapGesture commands are too slow (~535ms gap — each
-  resolves long after its gesture). Raw `Input.dispatchTouchEvent` delivers
-  touch events but does NOT reliably synthesize clicks on Android WebView.
- Word finder requires `range.getClientRects().length === 1`: a
-  hyphenated/wrapped word's bounding rect spans two lines, so its center taps
-  between lines and selects the neighboring word (saw `'party' !== 'sensation'`).
- `dismissSelection` picks a mid-column tap spot (0.78H or 0.25H) that the
-  `.selection-popup` doesn't cover — a blind 0.78H tap can press a toolbar
-  button when the selection sits low.
-
-**Other gotchas:** headless emulator display sleeps → adb `input` no-ops while
-CDP input still works (`input keyevent KEYCODE_WAKEUP`); a leaked single-click
-(broken double-tap) toggles header or opens the media viewer, contaminating the
-session; local repro = `pnpm tauri android build --debug --target aarch64` +
-`adb install -r` + `pnpm test:android`.

@ -11,7 +11,7 @@ Android "Open with Readest" / "Send to Readest" file-intent pipeline and the #45

 **Pipeline (ACTION_VIEW = "Open with", ACTION_SEND = "Share"):**
 - `NativeBridgePlugin.kt::handleIntent` is the real handler (NOT `MainActivity.kt` — its ACTION_SEND branch is legacy/redundant). → `emitSharedIntent("VIEW"|"SEND", uris)` → JS `useAppUrlIngress` `shared-intent` plugin listener → `app-incoming-url` event → `useOpenWithBooks`.
- VIEW routing is now gated by `autoImportBooksOnOpen` (PR #4747, issue #4746): `shouldOpenTransient(action, autoImportBooksOnOpen)` in `helpers/openWith.ts` → only `VIEW` with the setting OFF goes `openTransient` (ephemeral book, `deletedAt` set, `filePath` = content:// URI, no library write/upload); `VIEW` with it ON falls through to the SEND path. SEND (and VIEW-with-import-on) → `window.OPEN_WITH_FILES` → `library/page.tsx::processOpenWithFiles` (full ingest + force cloud upload on mobile). The setting defaults TRUE on mobile (`DEFAULT_MOBILE_SYSTEM_SETTINGS`, desktop default still false) and its "Auto Import on File Open" toggle is now shown on mobile too. `useOpenWithBooks.handle` reads it via `appService.loadSettings()` (disk), NOT the settings store — the store is unhydrated during the cold-start intent replay and would wrongly fall back to transient. So the Telegram default is now import-to-library (persists past the dying URI grant); transient is opt-out.
+- VIEW → `openTransient` → straight to reader (ephemeral book, `deletedAt` set, `filePath` = the content:// URI, no library write/upload). SEND → `window.OPEN_WITH_FILES` → `library/page.tsx::processOpenWithFiles` (full ingest + force cloud upload on mobile).
 - content:// read: `nativeAppService.openFile` → if URI contains `com.android.externalstorage` → direct `NativeFile` (real path); else `copyURIToPath` → `contentResolver.openInputStream` → copy to Cache → `NativeFile`. `basename` here is LEXICAL (`@tauri-apps/api/path`), not a ContentResolver `DISPLAY_NAME` query — but EPUB format is sniffed by zip magic (`document.ts isZip()`), so an extension-less content URI still opens.
 - The Tauri deep-link plugin's `getCurrent()`/`onOpenUrl` only fire for configured deep-link domains (`https://web.readest.com`, `readest:`); `content://`/`file://` VIEW intents are filtered out by `DeepLinkPlugin.isDeepLink()`, so file opens flow ONLY through the native `shared-intent` channel, never the deep-link plugin.

-Issue #4733 = add Android themed (Material You / monochrome) launcher icon. It had
-existed (#2122/#2153 added `ic_launcher_monochrome.png`) but PR #2353 ("fixed
-launcher icon size") rewrote the committed adaptive icon to inset the foreground
-22% and **silently dropped the `<monochrome>` layer**, so themed icons stopped
-working. Fix = re-add `<monochrome><inset android:drawable="@mipmap/ic_launcher_monochrome" android:inset="22%"/></monochrome>`
-to `ic_launcher.xml` + ship the monochrome mipmaps.
-
-**Android icon pipeline (non-obvious).** `src-tauri/gen` is gitignored, BUT specific
-customized res files are **force-added** (tracked): `mipmap-anydpi-v26/ic_launcher.xml`,
-`drawable/ic_launcher_background.xml`, `values/themes.xml`, `splash_icon.png`. CI
-(release/nightly/android-e2e) does `rm -rf gen/android` → `tauri android init` →
-`tauri icon ../../data/icons/readest-book.png` → **`git checkout .`** (restores the
-tracked customizations) → build. So **the committed gen files are the build's source
-of truth.** `tauri icon` (CLI 2.10.1) writes gen mipmaps + a DEFAULT `ic_launcher.xml`
-(foreground+background only) and does NOT emit a monochrome layer — so the monochrome
-PNGs (or a vector drawable) MUST be force-committed into `gen/.../res/` to survive
-`git checkout .`. `git add -f apps/.../gen/.../mipmap-*/ic_launcher_monochrome.png`.
-`src-tauri/icons/android/*` is the historical master but is NOT what the build reads.
-
-**Themed tint = SRC_IN (alpha only).** The launcher replaces the monochrome layer's
-RGB with the wallpaper tint, keeping only alpha → any fully-opaque artwork flattens
-to a solid blob (the original desaturated-logo monochrome lost all detail). Convey
-character via negative space. For Readest we kept the existing artwork and carved a
-**narrow vertical center-gap (spine)** via an alpha-multiply mask (ImageMagick:
-`magick src -alpha extract a.png; magick -size WxH xc:white -fill black -draw "roundrectangle ..." g.png; magick a.png g.png -compose multiply -composite na.png; magick src na.png -alpha off -compose CopyOpacity -composite out.png`),
-gap ≈ centered, width ~4% of content, from ~3%→84% of content height (pages stay
-joined at the binding). Preview-as-themed = tint `-colorize`, inset to central 56%
-(=22% inset), composite over dark bg, circular mask.
-
-**Emulator verify (Pixel_9_Pro AVD, Google Play image, NexusLauncher).** Themed icons
-toggle: Wallpaper & style (`am start -n com.google.android.apps.wallpaper/com.android.customization.picker.CustomizationPickerActivity`)
-→ "Home screen" tab → "Themed icons" switch. Only the **home screen/dock** is themed;
-the **app drawer keeps full color** (expected, not a bug). `uiautomator dump` returns
-"null root node" on the wallpaper picker (SurfaceView) → navigate by screenshot
-coords. Build for emulator = `pnpm tauri android build --debug --target aarch64 --apk`
-(NDK_HOME must be set). Gradle-standalone (`./gradlew :app:assembleUniversalDebug`)
-fails: the `rustBuild*` task shells `pnpm tauri ...` which panics at
-`tauri-cli/src/mobile/mod.rs:403` unless driven by `tauri android build`. Confirm the
-APK packaged it: `aapt2 dump xmltree --file res/mipmap-anydpi-v26/ic_launcher.xml app.apk`
-should show an `E: monochrome` node. Regression guard:
-`src/__tests__/android/themed-icon.test.ts` (asserts `<monochrome>` in the XML + a
-tracked monochrome mipmap per density). Related: [[dict-lookup-browser-hijack-4559]]

-
-PR #4735 (`fix/annotator-input-listener-leak`). Reported: reading a 3000-chapter web novel in **paragraph reading mode** on Android (Z Fold 7), paragraph transitions get sluggish after a few chapters and keep degrading until app restart. Classic per-section-transition resource leak.
-
-**Root cause — Annotator `onLoad` attaches listeners to objects that OUTLIVE the section.** `Annotator.tsx`'s `onLoad` (wired via `useFoliateEvents(view, { onLoad })` to the foliate `load` event, which fires once per section document load) did:
- `view.renderer.addEventListener('scroll', handleScroll)` — never removed
- `view.renderer.addEventListener('scroll', () => repositionPopups())` — anonymous, unremovable
- Android: `eventDispatcher.on('native-touch', handleNativeTouch)` — never `off`'d
-
-`view.renderer` is created ONCE per book (`createElement('foliate-view')` + `view.open()` in `FoliateViewer.tsx`), lives the whole session; the global `eventDispatcher` too. So every `load` permanently adds listeners. **foliate fires `load` for PRELOADED neighbour sections too** (`paginator.js#loadAdjacentSection` → `dispatchEvent(new CustomEvent('load',…))`, `#preloadNext` loads up to 8), so the accrual is several-per-chapter, not one. The doc-scoped `detail.doc.addEventListener(...)` listeners do NOT leak (the section iframe is destroyed by foliate's `#destroyView`, taking them with it). Only the renderer-/dispatcher-scoped ones leak.
-
-**Why paragraph mode + Android specifically.** Every paragraph advance calls `renderer.goTo({index, anchor})` (`focusCurrentParagraph`), which scrolls the renderer container → `paginator.js:~1161` `this.#container.addEventListener('scroll', () => { if(!#isAnimating) dispatchEvent(new Event('scroll')) })` → runs ALL accumulated scroll listeners. Normal paginated reading scrolls only on occasional page turns, so the same leak is far less felt. Cost is REAL on Android: `handleScroll` (useTextSelector.ts, the `#873` selection-pin workaround) early-returns unless `osPlatform==='android'`, then calls `getViewSettings`; `native-touch` is Android-only. Restart recreates the view/renderer → cleared (the reporter's workaround).
-
-**Fix = `useRendererInputListeners(view, {...})` hook** (`src/app/reader/hooks/`): registers the renderer `scroll` + (Android) `native-touch` listeners ONCE per view in an effect keyed `[view, enableNativeTouch]`, with cleanup; handlers routed through refs so re-renders never re-subscribe. The native-touch handler now resolves the CURRENT primary section's doc/index at fire time (`view.renderer.getContents().find(c=>c.index===primaryIndex)`) instead of capturing a load's doc/index (a load may be an off-screen preload — and the old code fan-fired EVERY loaded section's handler per touch, calling handleTouchEnd/handlePointerUp N times; new code fires once = strictly more correct). Dropped the redundant `scroll→repositionPopups` (a dedicated effect already repositions popups on scroll). `listenToNativeTouchEvents()` just sets one global `window.onNativeTouch` that re-dispatches `native-touch` via eventDispatcher — idempotent, fine to call once/view.
-
-**Reusable pattern (the lesson).** Listeners attached inside a per-section / per-event handler (`onLoad`, `load`, relocate, create-overlay) to an object that outlives that event (`view.renderer`, global `eventDispatcher`, `window`, `document`) LEAK one set per event. Audit `addEventListener`/`eventDispatcher.on` inside `onLoad`-style handlers: if the target isn't the per-section `detail.doc` (which dies with the iframe), it must move to a per-view `useEffect` with cleanup. `eventDispatcher` (`utils/event.ts`) stores async listeners in a per-event `Set` keyed by callback reference; fresh closures each call never dedupe → unbounded.
-
-**Verify gotchas.** Hook unit-tested with `renderHook` + a `MockRenderer extends EventTarget` tracking scroll listeners + a mocked `eventDispatcher` Set; assert size stays 1 across 20 re-renders, latest-handler routing, unmount→0, Android gate. NOTE: creating the mock `view` INSIDE the renderHook callback churns view identity → the `[view]`-keyed effect re-runs each render (still no leak — cleanup keeps Set at 1 — but `listenToNativeTouchEvents` call-count grows); hoist `view` outside to mirror the real stable `getView(bookKey)`. Needs on-device Android verification (Android-gated paths). Related: [[paragraph-mode-toggle-resume-4717]], [[tts-sync-paragraph-rsvp-3235]], [[android-nativefile-remotefile-io]].

-  scrollBy callback may stop() the scroller mid-tick; #tick re-checks active
-  before re-arming (test covers it).
- `useAutoScroll(bookKey, viewRef)` in reader/hooks, mounted in FoliateViewer:
-  scrolls `renderer.containerPosition += sign * delta`; sign = -1 when
-  `renderer.scrollProp === 'scrollLeft'` (scrolled+vertical), matching foliate
-  paginator.js `offset = -offset` for scrolled vertical (vertical-lr is a known
-  upstream FIXME). Manual wheel/drag composes with the paced steps by design
-  (no pause-on-wheel). Tap pause/resume consumes `iframe-single-click` via
-  eventDispatcher.onSync (same swallow mechanism as middle-click). Stall
-  detection: containerPosition unchanged ≥800ms → `view.next()` (hops sections
-  under noContinuousScroll) or stop + 'End of book' toast when
-  `renderer.atEnd`. Session state mirrored to readerStore
-  `viewState.autoScrollEnabled` (new setter) for the ViewMenu checkmark;
-  session never persisted, speed IS: `autoScrollSpeed` percent in BookLayout
-  (default 100 = 20 px/s base, 25-500 step 25, constants in
-  services/constants.ts).
- `AutoScrollControl` pill reuses the ParagraphBar chassis but positioned
-  `absolute` (NOT `fixed`): maintainer explicitly wants it centered on the
-  book's gridcell, not the viewport — pinned sidebar pushes the reading column
-  off window center. (ParagraphBar's #4474 comment argues the opposite for
-  paragraph mode; the two are intentionally different.) Fades after 2.5s while
-  scrolling, wakes on mousemove/pause, hidden while hoveredBookKey shows bars.
- Adding a field to readerStore ViewState breaks two test fixtures that build
-  ViewState literals (reader-store.test.ts, tts-auto-advance.browser.test.tsx).
- i18n: 6 new keys (Auto Scroll, Toggle Auto Scroll, Slower, Faster, Exit Auto
-  Scroll, End of book) hand-translated across all 33 locales following each
-  locale's existing Scrolled Mode / RSVP Slower-Faster terminology; scanner
-  extraction only touched trailing commas (no pruning this time).
-
-Verified live in dev-web with claude-in-chrome (localhost:3001): 20 px/s at
-100%, menu gating, pill geometry (pillCenterX == gridcell center != viewport
-center).

-#4703: Backup `.zip` exported on Windows wouldn't restore on any platform (Web/Android/Windows) — books restored with metadata but missing files/covers.
-
-**Root cause:** `appService.readDirectory` returns paths with the host separator. On Windows `nativeAppService.readDir` → `getRelativePath` strips the base prefix but leaves backslashes, so `file.path` is `hash\cover.png`. `addBackupEntriesToZip` used `file.path` verbatim as the zip entry name. Restore (`restoreFromBackupZip`) matches a book's files by `e.filename.startsWith(`${hash}/`)` (forward slash) → backslash names never match → all files silently skipped. (The "garbled Unicode" reported in zip viewers was just the `\` rendered oddly.)
-
-**Fix (export side only):** normalize the zip entry name to forward slashes — `file.path.replace(/\\/g, '/')` — in `addBackupEntriesToZip` (`src/services/backupService.ts`). Keep `file.path` (host separators) for `readFile`. Test: `backup-windows-paths.test.ts` drives the now-exported `addBackupEntriesToZip` with a capturing ZipWriter stub + Windows-style backslash listing (no zip.js workers needed; the forced `useWebWorkers`/`useCompressionStream` config makes a real round-trip impractical under jsdom).
-
-**General lesson:** `readDirectory`/`readDir` paths carry host separators; normalize to `/` at any cross-platform boundary (zip entries, sync keys, anything serialized for another device). Already-broken Windows backups still need re-export — restore was left unchanged (minimal fix; matches the issue's expected behavior). See [[platform-compat-fixes]].

-Feature #4811 SHIPPED (app PR #4939 merged 2026-07-05 as `ec45a08`; foliate-js#47 merged as `8485e93`): surface Calibre custom columns embedded in EPUB OPFs. Worktree and branches cleaned up.
-
-**Calibre OPF encodings (verified against calibre source opf2.py/opf3.py):**
- OPF2: one `<meta name="calibre:user_metadata:#label" content="{json}"/>` per column; label must start with `#`
- OPF3: a single `<meta property="calibre:user_metadata">{"#label": {...}}</meta>` (raw property attr always literally `calibre:user_metadata`; the `calibre:` prefix maps to `https://calibre-ebook.com` but foliate's URL-resolution concatenates without `:` so match the RAW attr, not the resolved one). Calibre prefers OPF3 over OPF2 when both present (`read_user_metadata3 || read_user_metadata2`).
- Value in `#value#` (array for multi-value), series index in `#extra#`; datetimes wrapped `{"__class__": "datetime.datetime", "__value__": "<ISO>"}`, unset date = `0101-01-01`; embedded files carry EVERY library column so empty values (null/''/[]/rating 0/undefined-date) must be dropped at parse time.
-
-**Where things live:**
- Parser: `getCalibreUserMetadata` in foliate-js `epub.js`, attached AFTER `tidy()` (tidy would collapse single-element value arrays) as `metadata.calibreColumns` `[{label, name, datatype, value, extra?}]`
- Type: `CalibreCustomColumn` in `src/libs/document.ts`; `BookMetadata.calibreColumns`
- Formatter: `formatCalibreColumnValue` in `src/utils/book.ts` (rating → ★ half-stars /2, series → `Name [idx]`, bool → ✓/✗, comments → strip tags, datetime → formatDate)
- UI: extra grid cells in `BookDetailView.tsx` Metadata section after Identifier (column names are user content, NOT i18n keys)
- Search: `getCalibreColumnsText` in `src/app/library/utils/libraryUtils.ts` `createBookFilter` (both regex and substring branches)
-
-**Why safe:** metaHash dedupe uses only title/authors/identifiers; metadata editor spreads `{...metadata}` so the field survives edits; import assigns `loadedBook.metadata` as-is. Calibre plugin pushes already embed user metadata via calibre `set_metadata`, so plugin-pushed books get columns through the same OPF parse (the plugin's flat `customColumns` wire field is a DIFFERENT shape and stays unused). E2E-verified on the real sample (Elena Sabe, OPF3, 11 columns → 7 shown, search "CT1" filters). Related: [[calibre-plugin-push-4863]].

-`apps/readest-calibre-plugin/` implements #4863: calibre GUI plugin pushing selected books + metadata into the Readest cloud, modeled on BookFusion's plugin. MERGED to main via PR #4918 (2026-07-04, merge 6b403d019); packaged in releases as `Readest-<version>.calibre-plugin.zip` by release.yml's `build-calibre-plugin` job.
-
-Design decisions and hard-won protocol facts:
- **Identity**: `Book.hash` = partial MD5 (KOReader algorithm; JS `1024 << -2` wraps to 0, so offsets are 0, 1024, 4096, ... 1024<<20). metaHash = `md5(NFC("title|authors,|ids,"))`, preferred id scheme uuid > calibre > isbn; Python impl verified byte-identical to `js-md5` output.
- **OPF embedding + uuid dedup** (v2, per maintainer request): metadata IS embedded into a temp copy at upload (`calibre.ebooks.metadata.meta.set_metadata` — deterministic for EPUB, writes custom columns as `calibre:user_metadata`). Dedup keys: calibre uuid in row `metadata.identifier` (survives byte changes) + `metadata.calibreSourceHash` = raw library-file partialMD5 (change detection, no local state; v1 rows fall back to `book_hash` which equals the raw hash). File changed → replace flow: upload new blob, push new row (carry-over) + tombstone old in one /sync POST, best-effort delete old cloud files. Metadata-only edit → row update, no re-upload (embedded OPF goes stale until next file upload).
- **POST /sync explicit-nulls absent fields** (transformBookToDB) — updates must carry over `uploadedAt`, `groupId/Name`, `progress`, `readingStatus*`, `coverHash` from the pulled server row (`wire.py::merge_for_push`); same lesson as koplugin syncbooks.lua.
- **Upload key** `Readest/Books/{hash}/{hash}.{ext}`; app's `{title}.{ext}` downloads resolve via download.ts hash+extension fallback. cover.png stores *original* bytes (app never converts formats, bookService.ts:568), so calibre's cover.jpg bytes upload as-is; coverHash = partialMD5 of those bytes.
- **OAuth from a non-app client works**: `{supabase}/auth/v1/authorize?provider=X&redirect_to=http://localhost:PORT` is whitelisted (readest-app's Flatpak/custom-OAuth production path uses it). Tokens arrive in the URL *fragment*; serve a page whose JS relays `location.hash` to `/callback?...` (tauri-plugin-oauth trick). Implemented in `oauth.py`.
- Pure modules (`api.py`, `wire.py`, `oauth.py`) are calibre-free; `make test` runs 56 unittests; `make zip` builds; smoke-test inside calibre with `calibre-debug -c` after `from calibre.customize.ui import find_plugin` (initializes the `calibre_plugins` namespace).
-
- **Release packaging** (PR #4918): `build-calibre-plugin` job in release.yml mirrors the koplugin job; perl-stamps `PLUGIN_VERSION` from readest-app package.json, `make zip` → `Readest-<version>.calibre-plugin.zip` release asset. Committed version stays the (0, 1, 0) dev placeholder.
- **Pushing workflow files**: gh's OAuth token lacks `workflow` scope (HTTPS push of .github/workflows/* rejected); SSH push works (transient hangs — retry with ConnectTimeout/ServerAliveInterval).

-Instant Highlight's 300ms still-hold gate ([[instant-highlight-tap-paginate]])
-worked in **push** mode but NOT in **slide/curl** — a swipe after the hold turned
-the page (with the slide/curl effect) instead of extending the highlight.
-
-**Root cause: two independent swipe paths.** foliate's native `#onTouchMove`
-(paginator.js) bows out at `if (this.hasAttribute('no-swipe')) return` (~2149),
-THEN checks `if (this.#scrollLocked) return` (~2162), THEN the `#layeredTurn` VT
-drag (~2179). So:
- **push** (no turn-style, no no-swipe) → native swipe, honors `#scrollLocked`. ✅
- **VT-layered slide** (`turn-style='slide'`, no no-swipe; engines with nested VT
-  groups) → native swipe → layered turn, still AFTER the scrollLocked check. ✅
- **captured curl (always) / captured slide (Tauri w/o full VT support)** →
-  `applyPageTurnAttributes` sets `no-swipe`, so native swipe returns early and the
-  APP-side captured-turn touch interceptor in `useCapturedTurn.ts` (priority 5,
-  driven by `iframe-touchmove` → `dispatchTouchInterceptors`) is the swipe handler.
-  It began a drag on any >15px horizontal move WITHOUT checking scrollLocked. ❌
-
-`useTextSelector.startInstantAnnotating` sets `view.renderer.scrollLocked = true`
-when the hold engages. The captured interceptor is a parallel reimplementation of
-swipe-to-turn and must honor the same lock independently.
-
-**Fix (app PR readest#5000 + foliate readest/foliate-js#51, tests:
-`useCapturedTurn-scrollLock.test.ts`):**
-1. foliate `paginator.js`: add `get scrollLocked()` — it was setter-only, so JS
-   couldn't read it back (app `src/types/view.ts` already declared it a readable
-   boolean). foliate PR #51 MERGED (squash → `ba57ec8` on foliate main); app
-   #5000 bumps the submodule pointer to `ba57ec8` (mergeable, awaiting merge).
-2. `useCapturedTurn.ts` touch interceptor, `move` phase, before starting a drag
-   (`!state` branch): `if (currentView.renderer.scrollLocked) return false;`.
-
-**Why the `!state` branch is sufficient:** a captured drag needs >15px horizontal
-travel, but `maybeCancelInstantHoldOnMove` cancels the hold at >10px — so a drag
-can never already be in progress when instant annotation engages; no need to gate
-an in-flight drag. See [[page-turn-styles-viewtransitions-555]].

CEO doc: `~/.gstack/projects/unknown/ceo-plans/2026-07-06-cloud-sync-provider-selection.md`.
-
-**Architecture:** policy layer over TWO engines (native DB-sync + FileSyncEngine) — Readest Cloud is NOT wrapped in FileSyncProvider (would regress server merges #4634/#4544/#4678). New `src/services/sync/cloudSyncProvider.ts`: pure `getCloudSyncProvider(settings)` derived from `webdav/googleDrive.enabled` (device-local) + separate `resolveCloudSyncGate(settings, plan)` w/ cached plan accessor (isCloudSyncAllowed needs async JWT — can't be settings-pure). Guard trips → PAUSED state + prompt, never silent readest fallback. Native gating = one branch in `syncCategories.isSyncCategoryEnabled` (book/progress/note); binary gating = `transferManager.queueUpload` returns null. Account channels (settings/stats/replicas/translations/Send) always native.
-
-**Sequence (user-ruled at gate):** PR1 quota decouple (#4959 hotfix: gate + quota-403 no-retry + BATCH toast dedupe — spam is N-books×1-toast after retries, verified transferManager.ts:376/395) → PR1.5 file-engine parity (tags+readingStatus in mergeBookConfig/mergeBookMetadata+wire, BEFORE gating) → PR2 exclusive gating + mixed-fleet detection → PR3 chooser UI.
-
-**Gate rulings:** UC3 = `syncBooks` AUTO-ENABLES on third-party selection (closes books-backed-up-nowhere hole; opt-out shows warning). UC1 = derived/device-local kept + read-only `/api/sync?since=providerSelectedAt&limit=1` probe → one-time "another device still syncs" banner + Sentry provider tag. UC2 = parity before gating. Switch-back = new-imports-only auto-upload (NO 675-book burst); metadata rows DO re-push (intended).
-
-**PR1 IMPLEMENTED (2026-07-06):** commit `f6e5d7740` on branch `fix/cloud-sync-quota-decouple` (worktree `/Users/chrox/dev/readest-fix-cloud-sync-quota-decouple`), 22 files, LOCAL ONLY (not pushed, per confirm-before-push). Full suite 6900 pass + lint clean; new suites: `cloudSyncProvider.test.ts` (18), `transfer-manager-gating.test.ts` (19). i18n extraction deliberately SKIPPED in this PR (scanner pruned ~1350 live translations, e.g. "Read Aloud" — run the dedicated /i18n pass later; new strings fall back to English keys). Deviations from plan, all sound: paused toast centralized in `handleBookUpload` (both manual surfaces route through it); useTransferQueue default-param hazard fixed by the manager-level settings barrier instead of signature churn; migration passes the settings snapshot into `runMigrations(lastVersion, settings)` and mutates in place because `Settings.loadSettings` re-reads disk (subclass post-save would clobber an independent save). **SERIES FULLY MERGED (2026-07-07): #4971 (PR1 quota) + #4973 (PR1.5 parity) + #4975 (PR2 exclusive routing, closes #4380) + #4976 (PR3 chooser UI).** Worktrees removed, local branches deleted. **LIVE-VERIFY BUG FOUND+FIXED = #4981 OPEN** (`3a0af54dd`, fix/file-sync-auth-abort): expired Drive web token → engine swallowed AUTH_FAILED on index pull → remoteIndex=null read as FIRST SYNC → attempted 682-book re-upload march; latent hazard: null index skips the peers-tombstone union in the final re-push (#4860 class — transient pull failure could resurrect deletions). Fix: unreadable index (throw) aborts (404→null stays first-sync); terminal AUTH_FAILED latch stops runPool + skips index push + rethrows; web auto-sync preflights hasValidWebDriveToken.

-
-**PR3 contents:** activation moved to `src/services/sync/cloudSyncActivation.ts` (accepts 'readest'; component cloudSync.ts is a re-export shim); pure status matrix `cloudSyncStatus.ts` (getReadestCloudRowStatus/getThirdPartyRowStatus, fully tested — paused renders on the THIRD-PARTY row, not Readest row as plan sketch had it); Cloud Sync section (Readest-first radio rows, scope subtitle, role=radiogroup); Readest Cloud inline sub-page (Quota + NavigationRow to Account, never navigateToProfile from the row); premium branch keeps Readest row; capability Tips both directions in webdav/gdrive sub-pages; FileSyncForm Upload Book Files relabel; SyncCategoriesSection 'Managed by {{provider}}' description swap (toggles stay live).

Contents: syncCategories provider gate (book/progress/note, runtime override, user toggles persist); `persistActiveCloudProvider` single write path (chooser + both connect/disconnect flows + gdrive OAuth callback which had bypassed broadcast); minimal switch-only broadcast (`{enabled, providerSelectedAt}` — never credentials/cursors); **found+fixed PR1 integration bug: buildWebDAVConnectSettings pre-set `enabled:true` so fresh-connect never triggered the syncBooks auto-flip — builder is now activation-agnostic**; fileSyncStore `lastError` + `fleetNoticeShown`; `runActiveFileLibrarySync()` shared runner (menu tap + pull-to-refresh + BackupWindow all route via pullLibrary's provider branch — fixes "undefined book(s) synced"); SettingsMenu "Synced via {{provider}}" + quota caption + Auto-Upload hidden (also command palette `action.autoUpload` filtered, BookItem badge, TransferQueuePanel Upload All); mixed-fleet read-only probe (`pullChanges(providerSelectedAt,'books',...,1)` in useBooksSync's throttled interval, once-per-session toast); `providerSelectedAt` in both provider types + backup blacklist. Sentry cloudSyncProvider tag DEFERRED to TODOS (tagging is Rust-mediated via set_webview_info pattern — needs src-tauri command).
-
-**PR1.5 IMPLEMENTED (2026-07-06):** commit `f19fc6fa1` on `feat/file-sync-metadata-parity` (worktree `/Users/chrox/dev/readest-feat-file-sync-metadata-parity`, branched off origin/main independent of PR1), 4 files +253/-26, LOCAL ONLY. Full suite 6869 pass + lint clean. KEY FINDING: library.json already serializes FULL Book objects — tags/readingStatus were on the wire all along; the drop was `mergeBookMetadata`'s overlay (same gap as #4942 groups) + the reconcile predicate not firing on status-only changes. Fix: tags join the metadata LWW subset (raw assignment, removals propagate); readingStatus merges on its own `readingStatusUpdatedAt` clock (client mirror of #4634); new `shouldApplyRemoteBookMetadata` predicate (either clock) replaces `isRemoteBookMetadataNewer` in the engine reconcile filter (the old predicate stays exported). NO wire changes needed. PR2 stacks on PR1 (needs cloudSyncProvider.ts) — merge PR1 first or stack branches.
-
-**Key traps found in review:** `BACKUP_SETTINGS_BLACKLIST` does NOT exclude enabled flags/webdav.deviceId (plan text was wrong; PR1 adds deviceId/lastSyncedAt to blacklist); settings broadcast must carry ONLY `{enabled}` (password would leak; routine lastSyncedAt writes could revert a switch via slice LWW); Drive OAuth callback writes via appService.saveSettings bypassing broadcast → centralize `activateCloudProvider()`; `useTransferQueue()` DEFAULT params (`libraryLoaded=true`) in SettingsMenu/TransferQueuePanel are the real unguarded init path (barrier = `settings.version`); cancelled needs structured `cancelReason` + queue schemaVersion (`retryAllFailed` resurrects cancelled rows today; failed-includes-cancelled copy-pasted in 5 places); fileSyncStore is process-local — durable lastSyncedAt lives in provider settings.

-#4741: in paginated (non-scrolling) mode, extend a selection/highlight past the
-page edge by turning the page mid-gesture. Branch `feat/cross-page-highlight-autoturn`.
-
-**Extracted `src/app/reader/hooks/useAutoPageTurn.ts`** from `useTextSelector` —
-the corner-dwell auto page-turn (#1354), now **decoupled from the DOM selection**
-so selection-less gestures can drive it. API: `notePoint`/`noteAutoTurnPoint`
-(window-coord engagement point), `cancel`, `isAutoTurning`, `onAfterTurn(cb)`
-(Set of subs), `cornerAtPoint`, `readingAreaRect`. Liveness at dwell fire-time is
-an injected predicate, not `doc.getSelection()`: `noteCorner(corner, isInCorner)`.
-`useTextSelector` keeps the dual-signal native liveness (`pointerCornerNow ||
-caretCornerNow`); point-only callers use `noteAutoTurnPoint` (last-point liveness).
-Pure exports `getReadingAreaRect`, `turnForFocusBeyondPage`, `keyboardTurnDirection`.
-
-**Key trap:** the old `armDwell` required a valid DOM selection to turn. Instant
-Highlight (`user-select:none` + CFI overlay) and AnnotationRangeEditor (CFI
-overlay) have **no** DOM selection, so the machine refused to turn for them. The
-decoupling is what makes them work at all.
-
-**Four gestures, all feeding the one machine** (`useTextSelector` re-exposes
-`noteAutoTurnPoint`/`cancelAutoTurn`/`onAutoTurn` to the editors via `Annotator`):
-1. Instant Highlight drag — `handlePointerMove`/`handleNativeTouchMove` feed the
-   finger corner. `useInstantAnnotation` now **DOM-anchors the start** (`startPosRef`
-   = `{node,offset}` at pointer-down; `buildRangeFromAnchor` builds anchor->end each
-   move) so it survives the scroll; relaxed the pointer-up `distance<10` cancel with
-   `&& !previewAnnotationRef.current`. See [[instant-highlight-tap-paginate]].
-2. `SelectionRangeEditor` handle drag — already DOM-anchored the fixed end; just
-   feed `noteAutoTurnPoint(point)` + cancel + re-emit.
-3. `AnnotationRangeEditor` handle drag — `useAnnotationEditor` changed from
-   `handleAnnotationRangeChange(startPt,endPt)` (`buildRangeFromPoints` resolved BOTH
-   ends from window coords -> lost previous page) to `applyAnnotationRange(range,...)`;
-   component anchors the non-dragged end (`fixedAnchorRef`) + builds via
-   `rangeFromAnchorToPoint` like SelectionRangeEditor.
-4. `Shift+Arrow` keyboard adjust (#4728) — `useBookShortcuts.adjustTextSelection`,
-   after `extendSelectionFromContents`, **immediate turn-on-cross** (no dwell):
-   `keyboardTurnDirection(contents, getReadingAreaRect(...))` -> `view.next()/prev()`
-   when the extended focus leaves the page. Desktop-only; gated `!scrolled`.
-
-**After-turn re-emit:** active gesture subscribes `onAfterTurn` to rebuild its range
-from the held point onto the new page immediately (instant: `reapplyInstantAnnotation`;
-editors: `subscribeAutoTurnReemit` -> `updateFromDraggedPoint(lastPoint)`). Native
-selection does NOT subscribe (browser extends its own). The Android #873 scroll-pin

-description: Customize Toolbar preview rendered as a solid black bar in e-ink; preview surfaces copying bg-gray-600 need eink-bordered
-metadata:
-  type: project
---
-
-#4839: the Customize Toolbar sub-page (`AnnotationToolbarCustomizer.tsx`) toolbar **preview** Zone copied the live popup's `selection-popup bg-gray-600 text-white` but rendered as an unreadable solid black bar under `[data-eink='true']`.
-
-**Why:** the real reader popup earns its e-ink chrome from `.popup-container` (globals.css `[data-eink] .popup-container` → `bg base-100` + 1px `base-content` border). The preview Zone is a plain `<div>` with NO `popup-container`, so the dark `bg-gray-600` survived in e-ink; the base-content (inverted via `[data-eink] button`) chip icons then sat black-on-black.
-
-**How to apply:** any e-ink "preview" surface that mimics the live popup must scope the dark fill to non-e-ink (`not-eink:bg-gray-600 not-eink:text-white`) and add `eink-bordered` so e-ink renders it as `bg-base-100` + 1px `base-content` border (don't just rely on `eink-bordered`'s `!important` to override the gray — drop the gray in e-ink outright). Also fix copied white hint text (`text-white/70` → `not-eink:text-white/70 eink:text-base-content`) since the surface turns base-100. Chip icons need no change — they are `<button>`s, already inverted to base-content by the global `[data-eink] button` rule. Guard: render test asserts `.selection-popup` element carries `eink-bordered`. Verify rendered colors via `getComputedStyle` under `[data-eink]` (set `data-theme='default-light'` first or theme vars are unresolved → transparent); note daisyUI returns **oklch** not rgb — e-ink correct = bg `oklch(1 0 0)`, border/icon `oklch(0.2 0 0)`. PR #4841.

-Customize Toolbar (annotation bar, #4014, shipped v0.11.12) changes only applied
-to the book where edited, not globally. Fixed in PR #4760 (MERGED, squashed onto
-main as 7da5f8321).
-
-**Root cause:** `serializeConfig` (`src/utils/serializer.ts`) decides which per-book
-viewSettings to persist as overrides via `globalViewSettings[key] !== value` — a
-*reference* compare. It deep-clones the config first (`JSON.parse(JSON.stringify)`),
-so any **array/object** viewSettings value (`annotationToolbarItems`, and latently
-`paragraphMode`, `proofreadRules`, `ttsHighlightOptions`, `noteExportConfig`) is a
-fresh reference ≠ global → stored as a per-book override on **every** save (progress
-autosave serializes with settings each relocate). On reopen the merge
-`{ ...globalViewSettings, ...perBookOverrides }` lets the stale override shadow
-global → a global toolbar change never reaches already-saved books.
-
-**Fix (final — minimal, general, no special-casing):** compare viewSettings values
-by content, not reference. Added `isSameViewSettingValue(a,b) = a===b ||
-JSON.stringify(a)===JSON.stringify(b)`, used in the viewSettings reduce ONLY
-(searchConfig left on `!==` — it holds functions / large `results`). The field
-stays `annotationToolbarItems` in `AnnotatorConfig` (normal per-book viewSettings,
-honors the isGlobal "Apply to This Book" toggle). PR diff is just serializer.ts +
-serializer.test.ts.
-
-**Iteration history (user steered):** (1) a `GLOBAL_ONLY_VIEW_SETTINGS` exception
-forcing global save + strip/ignore per-book — rejected "don't make it an exception";
-(2) move field to `SystemSettings.globalReadSettings` — rejected "too much";
-(3) rename `annotationToolbarItems`→`annotationToolbar` for a clean slate — rejected,
-keep the original name (it's synced in globalViewSettings). Landing point: keep the
-name, fix only the serializer reference-compare bug.
-
-**Known limitation (no rename clean-slate):** existing books may carry a per-book
-`annotationToolbarItems` override from the buggy v0.11.12 build. The value compare
-stops new ones and drops an existing one on next save when it matches global, but
-does NOT retroactively clear an override whose content differs from current global —
-those books keep the stale toolbar until re-saved while equal to global. A follow-up
-one-time migration (clear persisted per-book toolbar overrides) would close this if
-needed.
-
-Tests: `src/__tests__/utils/serializer.test.ts` — array setting equal to global is
-not persisted; differing array still persisted.

-#4443 — adjustable dictionary popup font size (independent of the reading view).
-SHIPPED: merged to main via PR #4734.
-
-**The lever** = `DictionarySettings.fontScale` (number, default 1), set in
-Settings → Language → Dictionaries (`SettingsSelect`, 85–175%). Stored in the
-dictionary settings; SYNCED by adding `dictionarySettings.fontScale` to
-`SETTINGS_WHITELIST` (whole-field LWW, like providerOrder). `setFontScale` in
-`customDictionaryStore` + default-merge in `loadCustomDictionaries`
-(`?? DEFAULT_DICTIONARY_SETTINGS.fontScale`).
-
-**Plumbing**: `useDictionaryResults` returns `fontScale`; `DictionaryResultsBody`
-puts `data-dict-content` + inline `--dict-font-scale` on each per-tab container
-(the `setContainerRef` div). All CSS lives in `globals.css`.
-
-**Two non-obvious CSS facts that drove the design:**
-1. **MDict renders into a Shadow DOM** (`shadowHost.attachShadow`, the only
-   provider that does) → its body is unreachable by ordinary popup CSS.
-   `::part(dict-content)` is the ONLY hook. So `mdictProvider` sets
-   `body.setAttribute('part','dict-content')` AND adds a stable host class
-   `dict-shadow-host` (the `::part()` rule needs a host selector subject).
-   `--dict-font-scale` inherits across the shadow boundary, so the outer rule
-   `…::part(dict-content){font-size: calc(var(--dict-font-scale,1) * 0.875rem)}`
-   resolves it. The dict's own shadow CSS never targets our wrapper `<div>`, so
-   no cascade fight — em-based dict content scales from it, px-based stays fixed
-   (expected for a font-size lever).
-2. **Light-DOM providers size text with Tailwind `text-*` = root-relative `rem`**,
-   which a container `font-size` can't move. Fix = re-base the utilities to `em`
-   WITHIN `[data-dict-content]` only: `[data-dict-content] .text-sm{font-size:.875em}`
-   etc. Higher specificity than the bare utility + declared after `@tailwind
-   utilities` → wins, no `!important`. Container itself = `calc(scale * 1em)`.
-
-**Verify**: the CSS contract (em-rebasing + `::part` + var inheritance) needs a
-real browser — jsdom has no layout. Covered by
-`dict-popup-font-size.browser.test.ts` (scale 1 → 18/14/14px, scale 1.5 →
-27/21/21px, incl. the shadow body). Provider/store/whitelist sides have jsdom
-unit tests. See [[css-style-fixes]].

-Issue #4876: add a "speak" button to the dictionary popup so a looked-up word
-can be pronounced. Implemented on branch `feat/dict-popup-tts` (commit
-f2acafb4b, 2026-07-06). Button-only (no auto-speak); speaker icon sits inline
-left of the headword in the shared `DictionaryResultsHeader`, so it covers both
-the desktop `DictionaryPopup` and mobile `DictionarySheet`.
-
-Key file: `src/services/tts/wordPronouncer.ts` — a standalone single-word
-pronouncer, deliberately independent of the reader's `TTSController`:
- **Speak ASAP**: never calls `EdgeTTSClient.init()` (which wastes a round trip
-  synthesizing "test"). Calls `EdgeSpeechTTS.createAudioData()` directly; its
-  static LRU MP3 cache makes repeat words instant.
- **Dedicated Web Audio context** (`new WebAudioPlayer(() => new AudioContext())`,
-  NOT the module-shared context the reader uses) so pronouncing a word can never
-  resume/suspend or overlap an active read-aloud session. One extra AudioContext,
-  fine under WebKit's ~4 cap.
- **Gesture warmup**: `warmWordAudio()` must be called synchronously in the click
-  handler (the hook's `speakWord` does this) because `pronounceWord` resumes the
-  context only after a network await, outside WebKit's autoplay gesture window.
- **Engine order**: Edge wss -> Edge https proxy (`fetchWithAuth`, throws "Not
-  authenticated" when logged out) -> platform fallback. Fallback reuses the
-  existing `WebSpeechClient` (desktop/web) / `NativeTTSClient` (mobile app)
-  standalone via `genSSMLRaw(word)` + `setPrimaryLang(lang)`; the SSML default
-  `xml:lang="en"` is overridden by `parseSSMLMarks(ssml, primaryLang)`.
- `requestToken` guards staleness so a superseded in-flight synth bails.
-
-Hook: `useDictionaryResults` gained `isSpeaking` + `speakWord`; cancels on word
-change / unmount. Voice pick = `TTSUtils.getPreferredVoice('edge-tts', lang)`
-then first `isSameLang` match then `en-US-AriaNeural`.
-
-Tests: `src/__tests__/services/tts/wordPronouncer.test.ts` (Edge-first / fallback
-contract; jsdom has no AudioContext so `getPlayer()` returns null unless
-`globalThis.AudioContext` is stubbed + `WebAudioPlayer` mocked). Speak-button
-wiring test added to `DictionarySheet.test.tsx` (mocks the pronouncer module).
-
-NOT verified live: real audio playback + iOS gesture warmup (not unit-testable).
-Related: [[edge-tts-webaudio-engine]] (the WebAudio refactor that replaced the old
-blob-URL `createAudio` with `createAudioData`), [[ios-instant-dict-double-popup]].

-Branch `feat/edge-tts-webaudio` (worktree `/Users/chrox/dev/readest-feat-edge-tts-webaudio`, built 2026-07-04, NOT pushed) replaces Edge TTS per-sentence `<audio>` playback with a Web Audio pipeline: fetch MP3 at rate 1.0 (unchanged LRU + new in-flight dedup in `edgeTTS.ts`) → decode → `pcm.ts` silence trim → `timeStretch.ts` in-house WSOLA (pitch-preserved client rate, cache never refetches on rate change) → `WebAudioPlayer.ts` gapless scheduling. `SectionTimeline.ts` (measured > per-voice cps EMA in localStorage `readest-tts-voice-cps` > script defaults) powers a TTSPanel scrubber + media-session position/seekto. foliate-js fork branch `feat/tts-get-sentences` adds `getSentences` — fork PR must merge BEFORE the readest PR (submodule pin).
-
-**Why:** #3851 first-word clipping cause is a HYPOTHESIS (Android reporter reproduced with BT off); treat as falsifiable experiment. #2033 gaps = element restarts + ~300ms Edge trailing silence.
-
-**Load-bearing invariants (don't regress):**
- AudioContext is a module-level singleton, never closed — a fresh TTSController per tts-speak calls `stop()` not `shutdown()`, and WebKit caps ~4 live contexts (leak = permanent silence).
- Marks dispatch at AUDIBLE time (player chunk-start via onended, background-safe), never at fetch — else foliate's `#lastMark` runs ahead and prev/next/resume break.
- `endSession` fires session-end synchronously when nothing is unfinished — zero-chunk sessions (Edge outage) must not wedge controls in "playing".
- `ensureSharedAudioContext()` is called in the tts-speak gesture path BEFORE any await (WebKit autoplay window); `unblockAudio` silent element runs on ALL platforms (desktop Chromium media keys need a playing HTMLMediaElement).
- `abortSession` never suspends the context (warm output stream IS the #3851 fix); only user pause suspends.
- Word boundaries stay in original untrimmed media time; `getChunkPosition()` returns trim-relative clamped seconds; timeline sums TRIMMED durations.
- Inter-sentence CLICKS/POPS = the silence trim (`findSpeechBounds`) cuts at an amplitude threshold (0.005), NOT a zero crossing, so each buffer edge is a non-zero sample; the source steps to/from silence → click. NOT WSOLA (no-op at rate 1.0, cross-fades internal splices). Fix (commit a8643ec12, branch fix/android-bg-tts-media-session): `applyEdgeFade` in `pcm.ts` ramps ~3ms at both ends of the buffer's OWN copy (`buffer.getChannelData(0)` after `createMonoBuffer`) — never the `trimmed` subarray view (rate 1.0 aliases the decoded buffer). Trim + gap kept. Removing the trim instead would work (WSOLA DOES scale silence, so gaps stay rate-scaled) but doubles each gap to Edge's tail+lead silence.
- `POPUP_HEIGHT` in TTSControl.tsx is fixed and non-scrolling — grows to 200 only when a timeline-capable client is active.
-
-**Follow-up decided (2026-07-04, not yet planned): background TTS decoupling.** App-level TTSSessionManager owns the controller; reader hook becomes attach/detach. Matrix chrox chose: close book = keep playing (headless via `section.createDocument()`); reopen SAME book = seamless reattach (adopt session + `redispatchPosition()` + CFI re-anchoring — the highlighter already re-anchors ranges through CFIs, so cross-doc ranges are safe; swap text supply to rendered doc lazily at next section boundary); open a DIFFERENT book = TTS STOPS (not "keeps playing while browsing"); explicit stop / sleep timer = stops. Fiddly bit: `getCFI` without a rendered view. Recorded in branch TODOS.md.
-
-**How to apply:** Release gates before closing the issues (in plan Verification): WSOLA A/B listening test 0.2x-3x EN+CJK, Linux WebKitGTK decode (GStreamer), reporter-hardware beta (Soundcore Q20i iOS / Galaxy S22U screen-off), iOS lock-screen + interruption QA, e-ink `[data-eink] .range` fill check (NO eink range rule exists in globals.css), RTL slider direction. Plan + 35-decision audit trail: worktree `.agents/plans/2026-07-03-edge-tts-webaudio.md` (gitignored, local). i18n keys added ('This chapter', 'Chapter progress', 'Failed to seek', '{{elapsed}} of {{total}}') need the /i18n pass. Deferred follow-ups in TODOS.md incl. provider-agnostic local-TTS hedge ([[grimmory-native-sync]] unrelated).

-Issue #4687 — added a bindable **"Refresh Page"** page-turner action that triggers a deep e-ink full refresh (GC16) to clear ghosting. Shipped as **PR #4822 (MERGED)** (`feat/eink-screen-refresh-pageturner` → main, 55 files +470/-41), built in an isolated worktree off origin/main (worktree + branch since removed). Rebase note: origin/main's Drive-sync PR #4821 added `secure_item` native-bridge commands at the exact anchors I used (end of COMMANDS / handler list / structs / impls), so all 7 plugin files (build.rs, default.toml, commands.rs, desktop.rs, lib.rs, mobile.rs, models.rs) conflicted on apply — resolved "keep both" by re-adding `refresh_eink_screen` after the secure_item code; locales re-derived via script on main's current files; autogenerated permission files regenerated via `cargo check -p tauri-plugin-native-bridge`.
-
-**Frontend** (reuses the existing hardware page-turner binding machinery — see [[keyboard-selection-adjust-4728]] / `src/utils/keybinding.ts`):
- `keybinding.ts`: `'refresh'` added to `PageTurnAction` + `PAGE_TURN_ACTIONS` (so `resolvePageTurn` matches it). `matchesBinding` now accepts `undefined`.
- `types/settings.ts`: `HardwarePageTurnerSettings.bindings.refresh?: KeyBinding | null` — OPTIONAL (older persisted settings lack it; never migrate, optional-chaining handles absence). Default `refresh: null` in `constants.ts`.
- `PageTurnerSettings.tsx`: refresh slot rendered ONLY when `appService?.isAndroidApp && viewSettings.isEink` (the user-facing Eink-mode view setting, not just hardware detection).
- `usePagination.ts` `handleHardwarePageTurn`: branch `if (action === 'refresh') { if (appService?.isAndroidApp) refreshEinkScreen().catch(()=>{}); return true; }` BEFORE the page/section side/mode logic. Also added `bindings.refresh?.source === 'native'` to `hasNativeBinding` + the effect dep array so a media key bound to refresh still acquires page-turner key interception.
- `bridge.ts`: `refreshEinkScreen()` → `invoke('plugin:native-bridge|refresh_eink_screen')`.
-
-**Native generic refresh** (`EinkRefreshController.kt`, new) — the answer to "compatible with most e-ink devices, generic interface not brand SDK". Android has NO public e-ink API; each vendor patches `android.view.View`. Probe via reflection, stop at first success (patterns from KOReader android-luajit-launcher EPD controllers):
-1. **Onyx BOOX (Qualcomm)**: `View.refreshScreen(0,0,w,h, 34)` instance method. `34 = FULL(32)+GC16(2)`.
-2. **Tolino/Nook (NTX/Freescale)**: `View.postInvalidateDelayed(0L,0,0,w,h, 34)`.
-3. **Rockchip (Boyue clones)**: `View.requestEpdMode(View$EINK_MODE.EPD_FULL, true)`.
-
-Deliberately do NOT bundle the Onyx SDK (`com.onyx.android.sdk.*` classes aren't on-device unless bundled — reflection would always fail) and do NOT call Onyx `setWaveformAndScheme`/None (KOReader does, but it owns the update loop; Readest leaves system auto-update in place, so switching to manual mode could FREEZE later updates). Run on UI thread against `activity.window.decorView`; `success:false` (no controller) is a soft no-op, not an error. iOS Swift stub resolves `{success:false}`.
-
-**Plugin wiring** added across `models.rs`/`commands.rs`/`mobile.rs`/`desktop.rs`/`lib.rs` + `build.rs` COMMANDS + `permissions/default.toml` `allow-refresh-eink-screen` (build regenerates `reference.md`/`schema.json`/`commands/refresh_eink_screen.toml`). App uses `native-bridge:default` so no capability edit needed.
-
-**Verified on real hardware**: ONYX BOOX Leaf5 (`ro.product.manufacturer=ONYX`). `pnpm dev-android` build+install; via adb+CDP invoked `plugin:native-bridge|refresh_eink_screen` directly in the WebView → `{success:true}`, logcat `EinkRefresh: onyx full refresh requested` (the Onyx/Qualcomm `View.refreshScreen` path, decor view), and the user visually confirmed 5/5 full GC16 screen flashes in the reader. So the onyx path works on modern BOOX without SDK bundling or `setWaveformAndScheme` priming. (CDP socket is pid-bound `webview_devtools_remote_<pid>`; re-forward when the WebView process recycles — see [[cdp-android-webview-profiling]].)
-
-**i18n**: ran into [[i18n-extract-prunes-keys]] (scanner `removeUnusedKeys:true` deleted ~314 dynamic keys / huge churn). REVERTED the scanner output and added the single `"Refresh Page"` key MANUALLY to all 33 non-en locales (en is key-as-content, needs no entry), aligning each translation with the locale's existing `"Reload Page"`/`"Next Page"` terminology. `check:translations` green.

-#4791 — clicking **Annotate** on a selection eagerly creates a highlight (`note:''`)
-as the note anchor (`handleAnnotate` → `handleHighlight(true)` in `Annotator.tsx`),
-so the selection stays visible while the NoteEditor is open. Cancelling the note
-(Cancel button, overlay, Escape, switching books, closing the notebook) left that
-empty highlight leaked into config → showed as a stale card in the left-sidebar
-Booknotes list + a phantom yellow highlight.
-
-**Fix:**
- `handleHighlight` now returns the created `BookNote` only when it pushes a NEW
-  record (returns `null` when it restyles/toggles an EXISTING one — that record
-  predates the flow and must survive a cancel).
- `handleAnnotate` stores `created?.id` via `setNotebookNewHighlightId` (new
-  `notebookStore` field). This tracked id is what distinguishes a removable
-  placeholder from a pre-existing highlight; do NOT identify it by cfi (a fresh
-  selection can collide with an existing highlight's cfi).
- `removeEmptyAnnotationPlaceholder(booknotes, id, now)` in `annotatorUtil.ts`
-  tombstones (`deletedAt`) the live annotation with that id ONLY if it still has
-  no note text, and returns it so the caller tears the overlay down with
-  `removeBookNoteOverlays` across ALL views (`getViewsById`, symmetric with how
-  `handleHighlight` drew it).
- Cleanup is **presentation-driven**, not threaded through every cancel path:
-  `Notebook.tsx` runs `handleCancelNewAnnotation` from an effect whenever the
-  creation editor stops being presented (`!(isNotebookVisible && notebookNewAnnotation)`)
-  — catches Cancel/Escape/overlay/close/swipe/navigate — plus a second effect's
-  cleanup on `sideBarBookKey` change / unmount for book-switch (pinned) and
-  reader-close.
- Save survives the guard (placeholder gains note text) and also clears the
-  tracked id. `handleCancelNewAnnotation` has stable identity (empty deps) so the
-  effects don't re-fire mid-edit; it reads settings fresh via
-  `useSettingsStore.getState().settings` (stale-closure guard, see [[webdav-connect-nullified-4780]]).
-
-**Why id-set-LAST in handleAnnotate matters:** `setNotebookNewHighlightId` is
-called after `setNotebookVisible(true)` + `setNotebookNewAnnotation`, so no
-intermediate render has (editing=false AND a fresh placeholder id) — prevents the
-presentation effect from deleting the placeholder it just created.

-Readest's Apple App Store + TestFlight submission via fastlane (root `fastlane/Fastfile`, alongside the existing Android `upload_to_play_store` lanes). Builds are unchanged (`pnpm run release-ios-appstore` / `release-macos-universial-appstore` → `tauri build` + `xcrun altool --upload-app`); fastlane only does the post-upload App Store version + review submission and TestFlight distribution on the already-uploaded build.
-
-Lanes (per-platform, each does App Store review submit AND TestFlight, sharing a `submit_apple_build` helper): `release_ios`, `release_macos`. App Store via `upload_to_app_store(skip_binary_upload: true, ipa:/pkg:, platform: "ios"/"osx", submit_for_review: true, automatic_release: true, force: true, skip_screenshots: true, skip_metadata: false, release_notes:{"en-US"=>...}, promotional_text:{"en-US"=>...})`; TestFlight via `upload_to_testflight(distribute_only: true, app_platform: "ios"/"osx", distribute_external: true, groups:["Beta Testers"])`. App Store submit runs FIRST (it waits for build processing, which the TestFlight distribute then needs). `release_notes_text` parses `apps/readest-app/release-notes.json` (latest version by `Gem::Version`, drops notes matching `/\b(?:Android|Windows|Linux)\b/i`, prefixes each `– `). Auth: `app_store_connect_api_key`. Commands: `pnpm run submit-appstore-ios` / `submit-appstore-macos`.

-GOTCHA 1 (Tauri notarization): `tauri build` auto-notarizes the macOS App Store bundle whenever the FULL App Store Connect API key trio (`APPLE_API_KEY` + `APPLE_API_ISSUER` + `APPLE_API_KEY_PATH`) is in the build env. Notarization REJECTS App Store builds ("not signed with a valid Developer ID certificate" / "no secure timestamp") because they use an Apple Distribution cert — App Store apps are NOT notarized. So `APPLE_API_KEY_PATH` must stay OUT of `.env.apple-appstore.local` (the macOS build env). `asc_api_key` instead DERIVES the `.p8` path from the key id: `repo_path("apps/readest-app/private_keys/AuthKey_#{key_id}.p8")` (the keys are named `AuthKey_<KEYID>.p8`, same convention altool uses; honors an explicit `APPLE_API_KEY_PATH` when set, e.g. the iOS build env which DOES need it and iOS doesn't notarize).
-
-GOTCHA 2 (fastlane cwd): fastlane changes cwd to the `./fastlane` folder when EXECUTING a lane (`__dir__` is just "."), so raw `File.read("./apps/...")` breaks with "No such file". `fastlane lanes` only PARSES (doesn't run lane bodies) so it won't catch this — verify path-dependent lanes by actually RUNNING one. Fix = `repo_path(rel) = File.expand_path(rel, File.expand_path("..", __dir__))`, route every path (release-notes.json, .p8, ipa, pkg) through it.
-
-GOTCHA 3 (dotenv shadowing): bare `dotenv` on PATH is the Ruby gem (`-f` syntax); package.json scripts use the npm `dotenv-cli` (`-e` syntax) resolved from `apps/readest-app/node_modules/.bin`. The submit scripts run `dotenv -e .env.apple-appstore.local -- bash -c 'cd ../.. && fastlane release_*'` — the `cd ../..` is required because fastlane does NOT search upward for the `fastlane/` dir (pnpm runs scripts from `apps/readest-app`).

-#4683: in paginated fixed-layout (PDF / fixed-layout EPUB) **fit-width** mode, when a
-page is scaled taller than the viewport (`isOverflowY` true, host gets a vertical
-scrollbar), turning to the next page opened the new page **scrolled to the bottom**
-instead of the top. Root cause: `FixedLayout` host (`:host{overflow:auto;align-items:center}`
-in `packages/foliate-js/fixed-layout.js`) scrolls vertically; `#render`'s `transform`
-re-centered `container.scrollLeft` on every render but **never reset `container.scrollTop`**.
-On a page turn the freshly-shown page inherited the previous page's offset (≈ bottom, since
-the reader scrolled down to finish, and same-size pages share maxScrollTop).
-
-**Engine-specific — WebKit only.** WebKit (Linux WebKitGTK, iOS, macOS WKWebView)
-*preserves* a scroll container's offset when `#showSpread` swaps the flow content
-(old frame → `position:absolute;visibility:hidden`, new frame appended). **Blink**
-(Android WebView, Chrome, WebView2) *resets* scrollTop to 0 on that swap, so the bug
-never manifests there. Reporter was on Ubuntu/WebKitGTK `WebView 605.1.15`.
-
-**Fix:** new exported pure helper `computePaginatedScroll({elementWidth,containerWidth,scrollTop,pageTurn})`
-→ `{scrollLeft:(elementWidth-containerWidth)/2, scrollTop: pageTurn?0:scrollTop}`.
-Thread a `pageTurn` flag into `#render(side, pageTurn=false)`; set `true` ONLY at the
-3 navigation entry points (`#showSpread`, `#goLeft`, `#goRight`). Plain re-renders
-(ResizeObserver, zoom/scale-factor attr, pageColors, goToSpread same-index re-render)
-keep `pageTurn=false` so resize/pinch-zoom of a tall page does NOT jar to the top.
-Test: `src/__tests__/document/fixed-layout-paginated-scroll.test.ts` (pure-helper pattern,
-like [[booknote-view-autoscroll-4352]] sibling fixed-layout helper tests — the custom
-element can't be instantiated in jsdom: no ResizeObserver + getBoundingClientRect=0).
-
-**Verification recipe (the bug is NOT Android-reproducible):** CDP on Xiaomi showed
-`view.next()` already yields scrollTop 0 on Blink → can't distinguish fix on Android.
-Proved on REAL WebKit instead: auto-running HTML mirroring host CSS + `#showSpread` swap,
-opened via `open -a Safari file://…`, screenshot. Safari `AppleWebKit/605.1.15` (== reporter)
-showed scrollTop 420/440 (bug) without reset, 0 with reset. readest fixed-layout page turn
-goes through `view.next()`/`view.prev()` (`usePagination.ts`), the same path.

-Issue #4984: in fixed-layout (PDF) `spread='auto'` + portrait viewport, the page
-was shoved into one half of the screen ("weirdly separate") and almost every tap
-turned the page instead of opening the menu.
-
-Root cause (verified in Chrome): `FixedLayout.#render` in
-`packages/foliate-js/fixed-layout.js` already hides the non-target page in
-portrait (`if (portrait && frame !== target) display:none`) and scales the shown
-page as a single page, BUT it kept the spread-centering one-sided inline margin —
-left page `marginInlineStart:auto`, right page `marginInlineEnd:auto`. With no
-partner page to meet at the spine, that auto margin stranded the lone page in one
-half of the viewport whenever it was narrower than the viewport (any zoom < 100%,
-e.g. the issue's 50% zoom; or a page whose fit-scaled width < viewport width).
-The off-center page then sat over a page-turn tap zone (tap zones are
-view-relative: center 0.375-0.625 = menu, else turn — see `usePagination.ts`), so
-taps turned the page. Symptom 2 was a consequence of symptom 1.
-
-Fix MERGED (readest PR#4992 + foliate-js PR#50 squash -> foliate main f6dced2, readest submodule bumped to it): added pure `computeSpreadInlineMargins(portrait)`; in portrait
-both inline margins are `auto` (centered), in landscape one-sided (pages meet at
-spine). It sets BOTH margins explicitly (opposite side cleared to '') because
-frames are re-styled in place on rotation (ResizeObserver -> `#render`, no
-`#respread`), so a stale `auto` would otherwise linger. NOT fixed by forcing
-`spread='none'` in portrait — that duplicates the existing portrait-single-page
-path, needs app-layer orientation swapping + `#respread` (cache clear + re-nav),
-and overrides the user's chosen setting.
-
-Test: `src/__tests__/document/fixed-layout-portrait-single-page.test.ts`. Related:

-description: Google Drive file sync re-probes all 646 books every run (focus/Sync Now) because uploadedHashes never records no-source books; plus supabase focus events re-fire pullLibrary

-Diagnosed 2026-07-07 (web dev, valid Drive session). "Uploading N / 646" on every tab refocus and every Sync Now = full per-book Drive probe sweep (`files?q=name='<title>.epub' and '<hashdir>' in parents`, ~1 req/book), no actual byte re-upload.
-
-Two compounding causes:
-
-1. **File cursor never records books absent from this device.** #4856's `uploadedHashes` in library.json is only added on `uploaded` or `remote-matches` (needs local bytes for size compare) in `FileSyncEngine.syncLibrary` push loop (engine.ts ~line 806-815). On web, non-downloaded books → `loadBookFile` null → `no-source` → NOT recorded even though the HEAD probe already proved the remote file exists. So `needsFilePush` stays true for all 646 forever → O(library) every run. Toggle test: Upload Book Files off → 15 reqs (config cursor `isLocalNewer` works); on → 646.
-   Fix v1 (record remote-present no-source books, commit 900af1df1 on dev) proved INSUFFICIENT: Drive API inspection showed 654/690 hash dirs hold only cover.png+config.json, NO book file (only 36 files ever uploaded) — so there was nothing to record and the probe storm persisted.
-   Fix v2 (the real fix, on dev 2026-07-07, initially uncommitted): reorder `pushBookFile` to resolve the LOCAL source before any remote probe (`probeRemoteHead` closure, lazy); `no-source` now costs zero requests and the `remoteExists` plumbing from v1 was removed again. Test: 'spends no remote request on a no-source book' in engine-sync-paths.test.ts. The 654 books stay in booksToPush (progress counter still shows them) but the sweep is network-free. Their files land on Drive only when a device that HAS the bytes (desktop) syncs with Upload Book Files on; that device records the hashes and everyone skips thereafter.
-   Worktree was discarded per user; work continues directly on the bare repo dev branch (dev server localhost:3000 runs from there).
-
-Round 5 (dev, uncommitted): Tauri plugin:fs|exists storm (5726 IPC/sync) killed by making the LIBRARY ROW the ground truth for local file presence in `needsFilePush`: gate `hasLocalFile(b) = !!(b.downloadedAt || b.filePath)` (import/download/delete all stamp downloadedAt; mergeBookMetadata keeps it device-local, verified) + session-scoped `noSourceVerdicts` WeakMap (provider-keyed, updatedAt-keyed) that suppresses re-probes of DRIFTED rows (row claims file, fs disagrees). Per user decision: NO automatic row-correction — Full Sync is the single split-brain healer (bypasses gate + memo + uploadedHashes and audits the real fs). Incremental sync with clean state = zero local and zero remote per-book probes. Harness in engine-sync-paths.test.ts: row-gate test, drifted-row memo tests, fullSync bypass; #4856 fixtures stamped downloadedAt.
-
-Round 4 (dev, uncommitted): per-book cloud buttons (Book Details + bookshelf + open-non-local-book) route to the selected provider instead of the gated Readest Cloud queue ("Uploads to Readest Cloud are paused..." toast). `FileSyncEngine.downloadBookFile` (hash-dir listing resolves filename; stream on Tauri, buffered on web; cover+config best-effort) + `runActiveFileBookUpload/Download` in runLibrarySync.ts (stamps downloadedAt; caller persists via updateBook + toasts, existing transferMessages i18n keys). Reader hint parity same day: `remoteProgressApplied` in useFileSync dispatches 'Reading Progress Synced' hint on applied remote position. NOT done: provider path has no transfer-queue/progress UI; uploadedAt not stamped (means Readest-Cloud backup; provider uploaded-state could later key off index uploadedHashes).
-
-Round 2 optimizations (dev, uncommitted as of 2026-07-07 03:10): provider memoized per connection key in `createFileSyncProvider` (warm Drive idCache across reader hook / library auto-sync / Sync Now; `resetFileSyncProviderCache()` called on Drive connect/disconnect); `writeBinary` PATCHes cached id without files.list lookup (404 evict+fallback); dev-only request diagnostics `[gdrive] op ...` / `[gdrive] #n ...` in GoogleDriveProvider.
-Remaining per-run budget after round 2 (no-change run ~11 req, ~550 kB): index GET 269 kB + index PATCH 269 kB every run; books/ listing 40 kB; ~8 file-less orphan hash dirs (in neither index nor library) re-listed by discovery every run.
-Round 3 (dev, uncommitted, all TDD in engine-sync-paths.test.ts): (1) etag short-circuit — `remoteIndexCache` WeakMap keyed on the memoized provider in engine.ts; head(library.json) etag (Drive md5/WebDAV ETag) vs cached → reuse structuredClone'd index, skip GET + ENTIRE discovery scan (peer changes always rewrite library.json; legacy no-index uploads still found on session-first run + fullSync); cache dropped after own push. (2) no-op push skip — `indexDirty` check (syncedHashes/failures/uploadedHashes-set/emptyDirs-set/any local row absent-or-newer-or-tombstone-mismatched vs remote index); skipping also keeps peers' etags stable (a restamped copy would defeat fleet-wide change detection). (3) `emptyDirs` optional index field (wire.ts) — file-less candidate dirs recorded once, skipped by discovery unless uploadedHashes says the file arrived or fullSync; pruned only against a listing that ran. Idle run = 1 stat request; local-change run = stat + config pull/push + index PATCH (no GET, no discovery). engine-deletion-sync 'preserves remote tombstone' test updated to force a dirty run.
-
-2. **Every tab focus re-runs the library file sync.** supabase-js emits SIGNED_IN/TOKEN_REFRESHED on visibilitychange; `AuthContext.syncSession` does `setUser(newObject)` each time → `pullLibrary` (deps include `user`) recreated → `useBooksSync` effect `[user, useSyncInited, libraryLoaded, pullLibrary]` refires → `runActiveFileLibrarySync` (third-party provider path). Fix would be: key on `user?.id` / latch the initial pull. User decided 2026-07-07 to LEAVE THIS AS IS ("sync on focus is fine now that runs are O(changed)") — only cause 1 was fixed.
-
-Related: #4981 fixed the adjacent expired-token variant (aborting instead of marching with remoteIndex=null). Web Drive token is sessionStorage-scoped (tab-local, no refresh). See [[cloud-sync-provider-selection-plan]], [[webdav-filesync-refactor-plan]].

-Adding **Google Drive as a second `FileSyncProvider`** for the merged file-sync engine (the WebDAV refactor, PR #4784). Approved plan: `/Users/chrox/.claude/plans/floating-chasing-feather.md`. Research + reuse map: [[gdrive-sync-provider-research]]. Author of the reference (`ratatabananana-bit/Readest-google-drive-mod-patcher`, AGPL-3.0) granted explicit reuse permission; adapted files carry attribution headers.
-
-**Shipped across multiple PRs (decided at the autoplan gate; no BYO client, official iOS-type client only).**
-
-**PR1 — DONE (built, all gates green, committed locally, NOT pushed).** Branch `feat/gdrive-sync-core` (worktree `/Users/chrox/dev/readest-feat-gdrive-sync-core`), commit `1a0065818`. 25 files / ~2.6k lines, ~81 new unit tests, full suite 6377 passing + lint + format clean. Contents under `src/services/sync/providers/gdrive/`:
- `GoogleDriveProvider.ts` — Drive v3 over `FileSyncProvider`; id-addressed resolution + per-instance id cache; create-then-name upload; real `ensureDir`; `files.list` pagination; Retry-After 429/5xx backoff; per-path folder-creation locks + deterministic dup-collapse (smallest id); stale-id eviction; `mapDriveError` (403 split rate-limit→NETWORK vs permission→AUTH_FAILED). Factory `createGoogleDriveProvider(auth, fetchFn, {sleep?})`; streaming omitted.
- `auth/` — `pkce`, `parseRedirect` (target + CSRF, takes `expectedRedirectUri`), `reverseDnsRedirect`, `tokenStore` (no client secret), `oauthFlow` (DI).
- `PersistedDriveAuth.ts` — single-flight refresh + re-check, carries old refresh_token, one save; `accountLabel` via `about.get`.
- `driveTokenStore.ts` — `TokenPersistence` + `KeychainTokenPersistence` over keyed secure-KV; `createDriveTokenPersistence()` returns null off-Tauri (NO ephemeral fallback for refresh token).
- `driveRest.ts` — pure builders + pagination + `aboutUrl`.
- `buildGoogleDriveProvider.ts` (env client id + keychain), `file/providerRegistry.ts` (`createFileSyncProvider`/`getEnabledFileSyncBackends`).
- Shared `file/providerSemanticContract.ts` test helper run for BOTH WebDAV + Drive.
- `utils/bridge.ts` — TS wrappers `set/get/clearSecureItem` (`plugin:native-bridge|*_secure_item`).
-
-**DEVIATION from plan:** the native keyed secure-KV implementation (Rust desktop/mobile + Kotlin + Swift + permissions) was DEFERRED out of PR1 — nothing in PR1 calls it (no UI/sync wiring), and 4 languages of un-runnable native code don't belong in a "CI-testable, no-platform" PR. The TS contract exists + is mock-tested. Native impl lands with **PR3 (desktop OAuth)**, which first exercises it and can live-verify.
-
-**PR2 — DONE (foundation only; committed `9ba097ea2`, UNPUSHED, on same `feat/gdrive-sync-core` branch).** Full suite 6403 passing + lint + format clean.
- `GoogleDriveSettings` type (mirrors WebDAVSettings minus URL/creds/rootPath, +`accountLabel`) in `types/settings.ts` + `SystemSettings.googleDrive`; `DEFAULT_GOOGLE_DRIVE_SETTINGS` in `constants.ts`.
- `googleDrive.deviceId`/`lastSyncedAt` added to `BACKUP_SETTINGS_BLACKLIST` (backupService.ts) + backup-settings test.
- `webdavSyncStore`→`store/fileSyncStore.ts`: per-backend progress keyed by kind + GLOBAL library-sync mutex (`beginSync(kind,label)` returns false if another holds lock). Migrated `WebDAVForm` + `IntegrationsPanel`; WebDAV behavior unchanged. `fileSyncStore.test.ts`.
- **DEFERRED to PR3 (deliberate):** `useWebDAVSync`→`useFileSync` hook generalization + `WebDAVForm`→`FileSyncForm` extraction + visible Drive Integrations row/connect UI. Rationale: until Drive connects (needs OAuth), the multi-provider hook paths can't run and `FileSyncForm` would be a single-use abstraction (violates YAGNI); also the autoplan gates these on a live WebDAV Sync-now check. Do them WITH PR3.
-
-**PR3 — IN PROGRESS (3 commits, all gates green: full suite 6411 passing + rust fmt/clippy/test + lint/format). UNPUSHED on `feat/gdrive-sync-core`.**
- `ff1ffe717` native keyed secure-KV: `set/get/clear_secure_item` across Rust desktop (keyring keyed by item key) + mobile forward + models/commands/lib/build/default.toml + Kotlin (EncryptedSharedPreferences `readest_secure_items_v1`) + Swift (Keychain, service `com.bilingify.readest.secure-items`). Rust compiles+clippy+fmt clean; permission files regenerated (passphrase preserved).
- `602f41406` desktop OAuth machinery: `auth/oauthDesktop.ts` (`runDesktopDeepLinkOAuth`, DI, 3 tests) + `src-tauri/src/spawn_fresh_browser.rs` (registry default-browser cold-spawn on Windows / no-op macOS+Linux; winreg Windows-only dep; pure-helper tests; registered `#[cfg(desktop)]`) + `connectGoogleDrive.ts` (`connectGoogleDrive`/`disconnectGoogleDrive`, fail-loud token save, 4 tests). `DRIVE_FILE_SCOPE='https://www.googleapis.com/auth/drive.file'`.
- `5efbe6b2f` ingress filter: `isGoogleOAuthRedirectUrl` (scheme-prefix match) + filter in `useAppUrlIngress` dispatch so the reverse-DNS redirect never reaches book-import consumers (OAuth runner catches via own listeners). Tested.
-
-**Official client id PROVISIONED:** `209390247301-ctpmep68ppfa56r1b8tr35e4qi4p60kq.apps.googleusercontent.com` (iOS type, no secret, `drive.file`). Baked as default in `getGoogleClientId` (env `NEXT_PUBLIC_GOOGLE_CLIENT_ID` overrides); reverse-DNS scheme `com.googleusercontent.apps.209390247301-ctpmep68ppfa56r1b8tr35e4qi4p60kq` registered in `tauri.conf.json` desktop+mobile deep-link. Commit `7a2ac3671`.
-
-**Drive UI DONE (commit `c657c34f0`):** `FileSyncForm` (shared sync controls extracted from WebDAVForm, parameterized by kind, builds provider via registry; WebDAVForm refactored to use it, behavior unchanged) + `GoogleDriveForm` (OAuth Connect/account/Disconnect + FileSyncForm) + `googleDriveConnect.ts` (assembles env client id + keychain + desktop runner) + IntegrationsPanel "Google Drive" row gated on `appService.isDesktopApp`. Full suite 6412 green.
-
-**Cloud Sync redesign DONE (commit `1a31a8cbd`):** new "Third-party Cloud Sync" Integrations section with a unified "Cloud Sync" sub-page (`CloudSyncForm`) — WebDAV + Google Drive MUTUALLY EXCLUSIVE via `withActiveCloudProvider` (enabling one disables the other). Radio picker (AIPanel pattern) + shared `FileSyncForm`. WebDAVForm/GoogleDriveForm refactored to embeddable panels; Drive has a "configured-but-inactive" state (`accountLabel` present, `enabled=false`) with frictionless "Use Google Drive" re-activate (no re-OAuth); explicit Disconnect clears the keychain token. Temp concurrency probe removed (upload was already concurrency-4, confirmed).
-
-**Reader auto-sync DONE (commit `f5e07e50b`):** `useWebDAVSync`→`useFileSync` — the reader auto-syncs the single ACTIVE provider per-book while reading (pull-on-open, debounced push, cover/file). Async engine build (Drive keychain probe) held in state, pull-on-open waits for it; engine keyed on connection-relevant settings (not lastSyncedAt) to avoid re-probing keychain; deviceId/lastSyncedAt write the active provider slice; events renamed `*-file-sync`. WebDAV reader behavior unchanged.
-
-**Drive feature is functionally complete on desktop:** connect, manual Sync now, auto-sync while reading, exclusive provider switching. Live-verified: connected + synced a 675-book library.
-
-**DESKTOP PR OPENED: readest/readest#4821** (`feat/gdrive-sync-core`, rebased onto origin/main, all gates green incl. rust). Covers provider + OAuth + native KV + redesign (exclusive Third-party Cloud Sync section, inline radio switch) + reader auto-sync + **premium gating** (any paid plan via `isCloudSyncInPlan`; free sees upgrade CTA; reader auto-sync off for free). Rebase needed `git -c protocol.file.allow=always submodule update --init packages/foliate-js` (foliate-js drift, index wanted `6f1a190`).
-
-**PR #4821 review fix (pushed `5769682c5`):** CodeQL flagged `escapeDriveLiteral` (driveRest.ts) for not escaping backslashes — fixed (escape `\`→`\\` FIRST, then `'`→`\'`). Was the only review comment.
-
-**Both branches REBASED onto origin/main `324bb8a36` (was `7e78f80e1`). UNPUSHED, both gates green (lint+format+full suite: mobile 6483, resumable 6486). foliate-js submodule drift on rebase: origin/main now wants `0fa407c4c` (not in local submodule clone whose origin is the main checkout's modules dir); fix `git -C packages/foliate-js fetch https://github.com/readest/foliate-js.git 0fa407c4c... && git -C packages/foliate-js checkout 0fa407c4c...` (the `submodule update --init` shortcut FAILS here — local origin lacks the commit; must fetch from GitHub URL). Current commits: mobile `6728c94f0`(Android)+`8b3dd1cd5`(iOS); resumable `f7a1e5117`.**
-
-**Branch `feat/gdrive-mobile-oauth` (Android+iOS OAuth) — no longer stacked, off main. PR not opened yet.**
-
-**Android OAuth (PR4) DONE (commit `eb8e22081`, was `5583c9b38` pre-rebase).** `auth/oauthAndroid.ts` (`runAndroidOAuth` via existing `authWithCustomTab`, DI, 2 tests) + platform dispatch in `googleDriveConnect` (`osType()==='android'`→Custom Tab, else desktop) + Drive row shown on Android. NATIVE (device-verify pending, no Android toolchain in CI): `NativeBridgePlugin.kt` `handleIntent` resolves `com.googleusercontent.apps.<id>:/oauthredirect` via the same `pendingInvoke` as the Supabase callback; matching BROWSABLE intent-filter added to `gen/android/.../AndroidManifest.xml`.
-
-**iOS OAuth (PR5) DONE (commit `1230fb291`).** `auth/oauthIos.ts` (`runIosOAuth` via `authWithSafari({authUrl, callbackScheme})`; callbackScheme = `deriveReverseDnsRedirectScheme(clientId)` = bare `com.googleusercontent.apps.<id>` — ASWebAuthenticationSession matches on SCHEME not path; DI, 2 tests) + `AuthRequest.callbackScheme?` (nativeAuth.ts; Supabase keeps native `readest` default) + `resolveOAuthRunner` `os==='ios'`→runIos + Drive row on iOS (`isDesktopApp||isAndroidApp||isIOSApp`). `createDriveTokenPersistence` already works on iOS (Keychain via secure-KV). NATIVE (device-verify pending, no iOS toolchain in CI): Swift `auth_with_safari` uses `args.callbackScheme ?? "readest"` (`SafariAuthRequestArgs.callbackScheme: String?`); `Info-ios.plist` CFBundleURLTypes gains the reverse-DNS scheme. macOS Drive uses the desktop deep-link runner (NOT authWithSafari), so no macOS native change. Full suite 6477 green + lint + format + plutil OK.
-
-**Drive streaming upload/download DONE — own branch `feat/gdrive-resumable-upload` off origin/main (commit `0c9cc1a22`, UNPUSHED).** `uploadStream`+`downloadStream` on GoogleDriveProvider so book files stream from/to disk instead of buffering the whole file in the JS heap (buffered marshal of a large book across the WebView↔Rust bridge crashes the renderer on mobile — this unlocks Drive book sync on Android/iOS and flattens heap on desktop too). `driveRest.resumableCreateUrl`/`resumableUpdateUrl`; `uploadStream` opens a Drive resumable session (POST new `{name,parents}` / PATCH existing `{name}`, metadata in initiation so NO reparent follow-up), reads `Location` session URI, PUTs bytes via `tauriUpload`; `downloadStream` GETs `alt=media` to disk via `tauriDownload` + bearer. Attached **Tauri-only** (`isTauriAppPlatform()`); web keeps buffered fallback. Both swallow→`false` per provider contract (engine retries once). REUSES `@tauri-apps/plugin-upload` already shipped for WebDAV — NO new native code. Single-shot streaming PUT (not chunked mid-stream resume) — sufficient for the heap/OOM fix; chunked-resume-on-failure is a further enhancement. Full suite 6484 green + lint + format. **NOTE: changes desktop Drive book sync from buffered → streaming (previously live-verified buffered); device-verify the streaming path on desktop + mobile.**
-
-**ALL PRs MERGED to main/dev (dev @ `c6f2a83d9`).** Worktree `feat/gdrive-*` branches no longer needed; work continues in the MAIN repo `/Users/chrox/dev/readest` on `dev` (tracks `origin/main`; there is NO `origin/dev`).
- **#4821** desktop Drive cloud sync + premium Third-party Cloud Sync section.
- **#4824** Drive resumable streaming upload/download.
- **#4823** mobile OAuth (Android Custom Tab + iOS ASWebAuthenticationSession).
- **#4827** Android sync fix: retry THROWN transport errors in `withBackoff` (was 429/5xx only); `mapDriveError` classifies transport throws (incl. Tauri plugin's plain `error sending request` Error) as NETWORK. Root cause: Android pooled keep-alive connection to googleapis.com goes stale mid-sync → every files.list after the first batch threw; sync recovered on its own after ~3-4 min (reqwest evicting dead conns). The retry forces a fresh connection so recovery is fast + kills the error spam.

-**CODE COMPLETE + MERGED.** REMAINING (human/ops-only): (1) on-device re-verify with #4827 in the build — Android sync should no longer stall ~3-4 min / spam `failed to inspect hash dir`; iOS OAuth sign-in; desktop streaming book-sync re-check; (2) Google consent screen → Production (testing caps 100 users). NOTE: Android build auto-generates a deep-link intent-filter for the gdrive reverse-DNS scheme in `gen/android/.../AndroidManifest.xml` (duplicates the manual `gdrive-oauth` filter) — benign build drift, don't commit.
-
-**Google Drive on WEB via FULL-PAGE REDIRECT OAuth — DONE on branch `feat/gdrive-web-oauth` (was `feat/gdrive-web-gis`; local/unpushed; suite 6516 green).**
- **GIS popup ABANDONED:** `src/middleware.ts:55` sets `Cross-Origin-Opener-Policy: same-origin` on every web doc (Turso WASM/SharedArrayBuffer needs `crossOriginIsolated`). COOP same-origin SEVERS a cross-origin popup's opener handle → GIS's `popup.closed` poll reads true instantly → `popup_closed` fires while the popup is still open (diagnosed live). Can't relax COOP (breaks Turso); can't scope it (connect happens over Turso routes). So no popup OAuth on web.
- **Web flow:** full-page redirect (no `window.opener`, works under COOP). `auth/webRedirectFlow.ts` (implicit `response_type=token` — secretless Web client can't code-exchange; CSRF state+returnPath in sessionStorage; parse token from callback fragment) + `auth/webTokenStore.ts` (sessionStorage access token, no refresh token) + `WebDriveAuth.ts` (reads stored token, expired→AUTH_FAILED, `accountLabel` via about.get) + `app/gdrive-callback/page.tsx` (validates state, stores token, `withActiveCloudProvider(settings,'gdrive')`+label via `appService.load/saveSettings`, routes back). `buildGoogleDriveProvider` web branch: `new WebDriveAuth(globalThis.fetch)` (Drive REST CORS-ok; streaming Tauri-only→web buffered). `googleDriveConnect` web: Connect=`beginWebDriveRedirect` (navigates away, never resolves), Disconnect=`clearWebDriveToken`.
- **Official Web client id BAKED** `209390247301-585tc3dohg4c02588uvah5d32hg6dneq` (`getGoogleWebClientId`, env `NEXT_PUBLIC_GOOGLE_WEB_CLIENT_ID` overrides). **NO auto-refresh** (secretless browser client → no refresh token; Google blocks hidden-iframe silent renewal) → user reconnects per session; true auto-refresh needs a server-side token broker (Worker holds secret+refresh token) — deferred ("A for now").
- **OPS REMAINING:** add `https://web.readest.com/gdrive-callback` + `http://localhost:3000/gdrive-callback` to the Web client's **Authorized redirect URIs** (JS origins already set). Then live-verify `pnpm dev-web`.
-
-**PR3 REMAINING:**
- **LIVE VERIFICATION (needs the user — real Google sign-in):** `pnpm tauri dev` → add own Google account as a Test user in the consent screen (Testing mode caps + gates) → Settings → Integrations → Google Drive → Connect → browser → grant → "Connected as <email>" → add book / Sync now → confirm `Readest/books/<hash>/{config.json,cover.png}` in Drive. Windows cold-browser fallback.
- **Reader-hook auto-sync (deferred):** generalize `useWebDAVSync`→`useFileSync` (per-provider state maps, async Drive provider build in the hook) so Drive auto-syncs per-book while reading like WebDAV. Manual Sync-now already works without it; do after live-verifying the base.
- Consent screen → Production before GA (testing caps 100 users).
- PR4 Android OAuth (Custom Tab + manifest scheme), PR5 iOS OAuth (authWithSafari scheme param + Info-ios.plist). Later: Drive resumable upload for `syncBooks` on mobile.
- Ops/launch blocker: create Google Cloud project (iOS client, `drive.file`) + consent screen to production (testing caps 100 users).
- PR4 Android OAuth, PR5 iOS OAuth. Later: Drive resumable upload to unlock `syncBooks` on mobile.
- Ops/launch blocker: create the Google Cloud project (iOS client, `drive.file`) + set consent screen to production (testing caps 100 users).

-
-NEXT TASK (research done, not yet built): add **Google Drive as a `FileSyncProvider`** for the merged file-sync engine ([[webdav-filesync-refactor-plan]] / PR #4784). Researched reference: `github.com/ratatabananana-bit/Readest-google-drive-mod-patcher` (AGPL-3.0, same as Readest → can adapt WITH attribution). Reference patch saved at `~/.../scratchpad/gdrive-ref/` (extracted modules under `extracted/`).
-
-**The repo is a PATCHER**, not a fork: the whole impl is one squashed diff `tooling/mod/mod.patch` (13k lines) against Readest v0.11.12. Design/plan docs live in a SIBLING repo `readest-gdrive-sync-mod` (referenced in MOD.md, likely private — not in the patcher).
-
-**Their architecture = REPLACE Readest's native cloud sync with Drive** (library/progress/notes/stats). Two layers:
- `src/services/cloudprovider/` — REUSABLE: a backend-agnostic provider seam + OAuth. `CloudProvider.ts` (their interface), `GoogleDriveProvider.ts` (Drive v3 REST impl), `FakeCloudProvider.ts`, `buildDriveProvider.ts` (assembly), `googleAuth/*` (the OAuth layer).
- `src/services/drivesync/` — SKIP for us: their integration with the native-sync data model (driveMerge, statsMerge, DriveSyncClient, DriveBlobStore, jsonl, layout). We REPLACE this with our `FileSyncEngine`.
-
-**KEY: their `CloudProvider` is ~1:1 with our `FileSyncProvider`.** Map: getText↔readText, getBinary↔readBinary, putText/putBinary↔writeText/writeBinary, list↔list, stat↔head, deleteFile↔deleteDir. Their `CloudEntry` even carries `md5` (Drive checksum) — stronger than our size-only HEAD short-circuit. Extra on theirs: `isAuthenticated()`/`accountLabel()` (auth state) + `putBinary` `onProgress`. Missing on theirs: `ensureDir` (Drive auto-creates folders on write).
-
-**Recommended fit for US = Drive as a parallel `FileSyncProvider`** (like WebDAV), NOT replacing native sync. Reuses the whole engine (incremental/concurrency/merge). Build = (1) `createGoogleDriveProvider(settings): FileSyncProvider` adapting their `GoogleDriveProvider` (rename methods, map CloudEntry→FileEntry, head from stat, deleteDir from delete-folder-by-id, ensureDir = no-op since write auto-creates, rootPath='/'), (2) reuse `googleAuth/*` OAuth nearly as-is, (3) token persistence (the ONE big gap — see below), (4) settings UI + provider registry.
-
-**Drive specifics (vs WebDAV path-addressing):**
- **Drive is ID-addressed, not path-addressed.** Resolve a logical path (`Readest/books/<hash>/config.json`) segment-by-segment via `files.list` (name+parent queries), cache folder/file ids in a `Map<path,id>`. `driveRest.ts` = pure query/URL builders; `GoogleDriveProvider` owns resolver+cache.
- **`drive.file` scope** = app sees only files it created → Drive root is a safe private namespace (no appdata hidden folder; a visible "Readest" folder). Non-sensitive scope = no Google verification needed (unverified-app warning shows once).
- **Upload = create-then-name:** `uploadType=media` carries no metadata, so POST bytes to root → PATCH name + reparent (addParents=folder, removeParents=root). Overwrite = media PATCH on the existing id (preserves id/links).
- Endpoints: metadata `drive/v3/files`, media `upload/drive/v3/files?uploadType=media`. Folder MIME `application/vnd.google-apps.folder`.
-
-**OAuth (the hard part — every gotcha you flagged is CONFIRMED + implemented):**
- **One iOS-type Google client** (Bundle ID only, NO secret, NO SHA-1, App Check OFF) for BOTH Windows + Android. Redirect = reverse-DNS `com.googleusercontent.apps.<id>:/oauthredirect` (SINGLE slash) + PKCE. Client id derives the scheme (`reverseDnsRedirect.ts`). Client id is committed (not a secret). App Check must stay OFF (Android can't produce iOS attestation → would break everyone).
- Loopback dead for iOS clients (Google blocked 2022); embedded WebView blocked (`disallowed_useragent`). Reverse-DNS is the only no-SHA native redirect Google accepts.
- `oauthFlow.ts` — provider-agnostic orchestration, platform mechanics injected (DI, headless-testable). Arms `awaitRedirect` BEFORE `openUrl` (race fix). PKCE + `state` CSRF via `parseRedirect.ts`.
- **Android** (`oauthAndroid.ts`): Chrome Custom Tab via Readest's EXISTING native bridge `authWithCustomTab` (same as Supabase login) — NOT external browser (keeps Tauri Activity foregrounded so in-flight auth survives memory pressure; redirect resolves via a native Kotlin field that survives WebView reload). Register the client scheme as a BROWSABLE intent-filter (patcher injects into `tauri.conf deep-link.mobile`). MUST filter the OAuth redirect out of Readest's deep-link ingress (`useAppUrlIngress` via `matchesReverseDnsRedirect`) or it triggers a /library reload that kills the flow. `tauri android init` wipes the manifest → restore MANAGE_EXTERNAL_STORAGE etc.
- **Windows/desktop** (`oauthDesktopDeepLink.ts` + `spawn_fresh_browser.rs`): system browser + self-registered scheme (`deep_link().register_all()`, no installer/admin). Capture via `single-instance` (url=args[1]) + `onOpenUrl`. THE WINDOWS SUBTLETY: a browser process snapshots protocol associations at launch, so a browser already running before scheme-registration silently drops the redirect. Fix: open default browser first; if no redirect in `DEFAULT_FALLBACK_DELAY_MS=25_000`, re-open in a freshly-spawned COLD browser (`spawn_fresh_browser` Rust cmd: resolve default browser from registry UserChoice → if Chromium-family spawn with `--user-data-dir=<isolated>` → else fall back to Edge). Hard deadline `CONNECT_DEADLINE_MS=15min` rejects an abandoned sign-in. Whichever browser returns first wins.
- `tokenStore.ts` = PKCE token exchange + `refreshAccessToken` (Google omits refresh_token on refresh → keep the old one). `pkce.ts` = PKCE pair + `buildAuthUrl`.
-
-**GAPS / NOT in the reference (we'd build):**
-1. **Token persistence is a stubbed interface** (`TokenPersistence` load/save/clear) — they explicitly left the secret store (Tauri secure storage / Android Keystore) as a later task. WE implement it.
-2. **No resumable/streaming upload** — simple `uploadType=media` buffers the whole file in JS heap (same OOM risk our WebDAV `uploadStream` avoids). For large book files we'd add Drive resumable upload (`uploadType=resumable`); configs/covers are fine buffered. Our engine's streaming is optional (falls back to buffered).
-3. **accountLabel is a placeholder** ('Google Drive'); real email needs a userinfo call.
-4. **iOS/macOS** not covered (Windows + Android only).
-
-**License call:** AGPL→AGPL is compatible. **The author (ratatabananana-bit) granted EXPLICIT permission** (2026-06): "feel free to do whatever you want with the code (it's the AGPL fork - Drive sync + the recently-read shelf)." So we can copy-adapt freely; keep attribution/credit. The OAuth platform glue is the high-value, hard-to-reproduce part → adapt with credit. Note the author also mentions a "recently-read shelf" feature in the same fork (separate, potential bonus).

-
-Goal: add **native grimmory sync** to Readest (vs the current OPDS+KOReader-compat detour, which causes 3-way KOReader↔Kobo↔grimmory desync — see discussion grimmory-tools/discussions/1417). Grimmory repo at `/Users/chrox/dev/grimmory` (Java/Spring backend, package `org.booklore`).
-
-**Native API (use this, not KOSync):** JWT bearer. `POST /api/v1/auth/login` `{username,password}` → `{accessToken,refreshToken,expires}` (2h/30d); `POST /api/v1/auth/refresh`. Progress: `POST /api/v1/books/progress` `{bookId, fileProgress: BookFileProgress{bookFileId, progressPercent 0-100, positionData (CFI for EPUB), positionHref, ttsPositionCfi}, dateFinished}`; `GET /api/v1/books` to list — **the Book DTO does NOT expose the file hash** (no native hash lookup endpoint; match by metadata, see below). Annotations `/api/v1/annotations/**`, bookmarks `/api/v1/bookmarks/**`, download `/api/v1/books/{id}/download` (Range OK), cover `/api/v1/media/{id}/cover`. KOReader-compat path exists at `/api/koreader/**` (X-Auth-User + X-Auth-Key=md5(pw)) but is the thing we're replacing.
-
-**CORS (`SecurityConfig.java`): per-filter-chain only — NO global CorsFilter/addCorsMappings.** Policy (`:340-368`): origins default `*` (env `ALLOWED_ORIGINS`, uses `setAllowedOriginPatterns` so `*`+credentials valid); methods all; **allowed-headers is a FIXED whitelist** = `Authorization, Cache-Control, Content-Type, Range, If-None-Match, If-Modified-Since` (NOT `*`, and **excludes X-Auth-User/X-Auth-Key**); allowCredentials true. Chains WITH `.cors()`: jwtApi (order10: `/api/**` minus whitelist → books/progress/annotations/bookmarks/reading-sessions/koreader-users), bookDownload(8), epub/audiobook/custom-font/ws(5-9). Chains WITHOUT `.cors()`: opds(1), komga(2), **koreader(3)**, kobo(3), **media/cover(4)**, **catch-all static(11)**. CRITICAL GAP: `/api/v1/auth/login` + `/auth/refresh` are whitelisted OUT of order10's matcher (`:265-289`) so they hit order11 catch-all = **no CORS** → cross-origin browser login fails (invisible to grimmory's own SPA, served same-origin from `classpath:/static/`).
-
-**What it means for Readest:** Tauri desktop/mobile = CORS irrelevant (`@tauri-apps/plugin-http` is native, all endpoints work incl. login). Readest **web build** = JWT data endpoints work cross-origin once token obtained, but **login + koreader need a server-side proxy** (same pattern as existing `/api/kosync`, `/api/opds/proxy`) or same-origin reverse proxy.
-
-**Readest extension points (template = KOSync):** new `src/services/grimmory/GrimmoryClient.ts` (connect/getProgress/updateProgress mirroring `KOSyncClient.ts`), `src/app/reader/hooks/useGrimmorySync.ts` (mirror `useKOSync.ts`), `GrimmorySettings` in `src/types/settings.ts`, `GrimmoryForm.tsx` wired into `IntegrationsPanel.tsx`. Progress mapping: Readest `BookProgress.location` (CFI) ↔ grimmory `BookFileProgress.positionData`; grimmory has `EpubCfiService` for CFI↔XPointer. Related: [[kosync-cfi-spine-resolution]], [[kosync-connect-false-positive-4692]].
-
-**STATUS: NOT shipped.** A full vertical slice was built on 2026-06-23 (GrimmoryClient + useGrimmorySync hook + `/api/grimmory` proxy + GrimmoryForm/IntegrationsPanel + settings/types; metadata-match identity cached in BookConfig; native `/api/v1/books/progress`; tests+lint green) then **REVERTED at the maintainer's request ("not ready yet")**. Working tree fully restored (all grimmory files deleted, the 7 edited shared files reverted; lint + test green). Re-attempt later — the design below + the two findings below are the distilled learnings. Reverted because the native-progress identity story was judged immature; the more robust paths (OPDS acquisition capture, or mirroring the official koplugin) hadn't been built yet.
-
-**FINDING A — how the OFFICIAL koplugin (`github.com/grimmory-tools/grimmory.koplugin`) maps identifiers (it does NOT use `/api/v1/books/progress`).** Local SQLite `book(book_path, partial_md5, grimmory_id)` stores BOTH ids per file. TWO paths: (1) native `grimmory_id` (= book.id) for sessions/downloads/shelves, resolved by **ISBN13/ISBN10/ISBN/ASIN only** (`doc_metadata.lua isBook` — NOT title/author), persisted via `repository.upsertBook(path, book.id)`; sessions → `POST /api/v1/reading-sessions` keyed by grimmory_id. (2) reading **PROGRESS via the KOReader-compat endpoint** `GET/PUT /api/koreader/syncs/progress[/{partialMD5}]`, keyed by KOReader's own `util.partialMD5(book_path)` (NOT grimmory_id), with creds auto-provisioned from native `GET/PUT /api/v1/koreader-users/me` (`getKoreaderCredentials` → `md5(secret)` → X-Auth-User/X-Auth-Key). ⇒ The proven progress path reuses our existing KOSync XPointer/partial-MD5 machinery against `/api/koreader/...`, not the native progress API. Caveat: backend `FileFingerprint.generateHash` samples i=-1 at `1024L<<-2` → Java overflow to offset **0**, vs KOReader LuaJIT `bit.lshift(1024,-2)` → offset **256**; first block MAY differ ⇒ partial-MD5 progress-by-hash could silently mismatch — VERIFY (hash one real downloaded file both ways) before relying.
-
-**FINDING B — OPDS acquisition-time capture (the chosen "best match", not yet built).** Grimmory OPDS fingerprints (`OpdsFeedService.java`): every `<id>` is `urn:booklore:*` (root `urn:booklore:root`, books `urn:booklore:book:{bookId}`); feed `<title>Booklore Catalog`; self/start link `/api/v1/opds`. The book acquisition link encodes BOTH ids: `<link href="/api/v1/opds/{bookId}/download?fileId={fileId}" rel="http://opds-spec.org/acquisition">`. So at OPDS download (`src/app/opds/page.tsx` ~line 505 has `url`; already persists sourceUrl via `upsertOPDSSourceMapping`) parse `bookId` (path) + `fileId` (query); corroborate via `urn:booklore:` entry id OR same-origin with configured grimmory serverUrl; write the ids into config. Authoritative, no metadata guessing — best identity strategy for grimmory-sourced books.
-
-Identity options ranked (native path): (1) OPDS acquisition capture [authoritative]; (2) cached ids; (3) ISBN/ASIN exact; (4) gated title+author (require format + fileSizeKb match, abstain on ambiguity — wrong match corrupts another book's progress). `fileSizeKb` IS exposed on BookFile (size corroborator); hash is NOT.

-Issue #4792 (v0.11.12) — FIXED in PR #4794 (branch `fix/hardcover-progress-edition-id`). "Hardcover sync fails completely despite successful API key auth." Auth (`GetUserId`) works; progress push fails with:
-`GraphQL Errors: [{"message":"parsing Hasura.GraphQL.Execute.Action.Types.ActionWebhookErrorResponse failed, key \"message\" not found","extensions":{"code":"parse-failed"}}]`
-
-**Root cause (verified live in Chrome, account chrox, book "Crime and Punishment"):** `HardcoverClient.pushProgress` → `MUTATION_UPDATE_READ` (`update_user_book_read`) sent `edition_id: 713309`, which is the **book_id**, not a real edition id. `update_user_book_read`/`insert_user_book_read` are Hardcover **Hasura Actions**; an invalid edition makes the Action handler throw and return a non-conforming error body, which Hasura surfaces as the generic `parse-failed` (`ActionWebhookErrorResponse` missing `message`). HTTP status is 200 — the error is GraphQL-level only.
-
-**Why edition_id == book_id:** title-search path in `fetchBookContext` (`HardcoverClient.ts`). `QUERY_SEARCH_BOOK` (`per_page:1`, returns raw `results`) does **not** select `featured_edition_id` — confirmed the hit `document` has no such key. So `searchBookByTitle` does `editionId = featured_edition_id ?? bookId` → always `bookId`. Then `QUERY_GET_BOOK_USER_DATA` only resolves a real edition via `selectedEdition` (the user_book's / read's `edition`); here both were `null` (user added the book with no specific edition), so `editionId` stays `bookId`. Broad impact: any no-ISBN (title-matched) book whose Hardcover library entry has no edition selected sends `edition_id = book_id`.
-
-**Fix shipped (PR #4794):** `BookContext.editionId` is now `number | null`; `searchBookByTitle` drops the `?? bookId` fallback (null when no `featured_edition_id`); `$edition_id` made nullable (`Int`) in `MUTATION_INSERT_READ`/`MUTATION_UPDATE_READ`/`MUTATION_INSERT_JOURNAL`; `insert_user_book` omits `edition_id` when null. Verified live: book id → `parse-failed`; real edition id → `error:null`; `edition_id:null` → `error:null` and is a no-op (does NOT clear an existing edition).
-
-**NOT a recent Readest regression:** the buggy `editionId = featured_edition_id ?? bookId` fallback + `edition_id: context.editionId` in the read mutations exist unchanged since the original feature #3724 (2026-04-03). It surfaces now because auto-sync (#4614, 2026-06-16, shipped v0.11.10/v0.11.12) made progress-push run automatically on every page turn (debounced) and via the BookMenu "Hardcover Sync → Push Progress". Possibly compounded by Hardcover tightening server-side edition validation. Secondary: title search also mis-matches (e.g. matched a Harold Bloom study guide, not Dostoevsky's novel) — separate match-quality concern.
-
-Files: `src/services/hardcover/HardcoverClient.ts` (`fetchBookContext` ~306-426, `searchBookByTitle` ~286-289, `pushProgress` ~499-536), `src/services/hardcover/hardcover-graphql.ts` (`QUERY_SEARCH_BOOK`, `MUTATION_UPDATE_READ`/`MUTATION_INSERT_READ` ~131-155). Proxy: `src/app/api/hardcover/graphql/route.ts` forwards client `authorization` header.

-`pnpm run i18n:extract` (i18next-scanner, `i18next-scanner.config.cjs` has
-`removeUnusedKeys: true`) can DELETE ~30+ valid-looking keys from every non-`en`
-locale on a feature branch — keys whose source usage isn't statically present in
-the current branch (e.g. `"Sync History"`, `"downloaded {{n}} book(s)"`,
-`"Match Whole Words"`). The extract diff then shows huge churn (~1000 +/- lines)
-unrelated to your change.
-
-**Why:** the committed locales can be ahead of the branch's source (strings from
-features not yet on this base, or built dynamically/in non-scanned modules), and
-`removeUnusedKeys` strips anything the scanner can't find. `en/translation.json`
-is a tiny key-as-content file (~70 lines, only plural/proper-noun overrides), so
-new keys never land there anyway — it stays out of the diff.
-
-**How to apply:** for a feature that adds a few strings, do NOT commit the
-scanner's deletions into an unrelated PR.
-1. Run `pnpm run i18n:extract` (optional — only confirms which keys are new).
-2. `git checkout -- apps/readest-app/public/locales` to drop ALL the churn.
-3. Add ONLY your new keys manually to each locale in `i18n-langs.json` with real
-   translations. The files are exactly `JSON.stringify(obj, null, 2) + "\n"`, so
-   a Node script that `JSON.parse`s, appends new keys (insertion order preserved),
-   and rewrites that way yields a zero-extra-diff result. Skip `en` (key-as-content).
-
-Match each locale's existing terminology (grep the file for a related key, e.g.
-`"Export Annotations"` / `"Annotations"`, before translating). Verify with
-`grep -rn '"<Your Key>"' apps/readest-app/public/locales | wc -l` == number of locales.

-Double-tap (touch) / double-click (mouse) on a word now selects that word — like
-a long-press — then runs the configured instant quick action, or raises the
-annotation toolbar if none is set. Verified live on Xiaomi 12 (Android).
-
-**The gap:** `iframe-double-click` was posted by `handleClick`
-(`src/app/reader/utils/iframeEventHandlers.ts`, gated on `!doubleClickDisabled`)
-but had **no consumer** — a touch double-tap did nothing (Android has no native
-double-tap word-select; desktop double-click already selects natively via the
-`handlePointerUp` path).
-
-**Impl (3 files):**
- `src/utils/sel.ts`: `getWordRangeAt(node, offset)` expands a caret to the
-  word-like segment via `Intl.Segmenter` (CJK + Latin), `[start,end]` inclusive
-  so a boundary caret still selects the adjacent word; `getWordRangeFromPoint(doc,x,y)`
-  resolves the caret (`caretPositionFromPoint`/`caretRangeFromPoint`) then delegates.
- `useTextSelector.ts`: `handleDoubleClick(doc, index, x, y)` selects the word and
-  routes through the existing `makeSelection` (guarded so the programmatic
-  `selectionchange` echo is ignored). **Guard `if (isValidSelection(sel)) return`**
-  — on desktop the browser already selected the word natively (flows through
-  `handlePointerUp`), so synthesize ONLY when nothing is selected (touch double-tap).
-  No `isUpToPopup` latch: a double-tap is two taps both consumed by double-click
-  detection, so no trailing single-click follows that would dismiss the popup.
- `Annotator.tsx`: window `message` listener for `iframe-double-click` resolves the
-  visible section doc/index like `handleNativeTouch` (`renderer.getContents()` +
-  `primaryIndex`), then sets **`pointerDownTimeRef.current = 0`** before calling
-  `handleDoubleClick` so the deliberate double-tap bypasses `handleQuickAction`'s
-  `quickActionMinHoldMs` (300ms) long-press gate (mouse already uses 0). Coords:
-  `clientX/clientY` from the iframe click are already section-doc-relative, exactly
-  what caretFromPoint wants — no window↔frame mapping (unlike `rangeFromAnchorToPoint`).
-
-The branch decision (instant action vs toolbar) reuses the existing Annotator
-`selection` effect: `enableAnnotationQuickActions && annotationQuickAction &&
-isTextSelected.current ? handleQuickAction() : handleShowAnnotPopup()`. Default
-config has `annotationQuickAction: null` → toolbar.
-
-**Tests:** unit `sel.test.ts` (getWordRangeAt/FromPoint), `useTextSelector-doubleClick.test.ts`

-ImageViewer (`src/app/reader/components/ImageViewer.tsx`) flickered when zooming an open image with a MacBook trackpad pinch (#4742, PR #4748).
-
-**Root cause:** on macOS a trackpad pinch-to-zoom is delivered to the WebView as a rapid stream of `wheel` events with `ctrlKey: true` (NOT touch events), so it flows through `handleWheel`. The zoomed `<img>` kept its `transition: transform 0.05s ease-out` whenever `isDragging` was false. Pinch wheel events fire faster than 50ms apart, so each event restarted the in-flight transition from its interpolated mid-point — the transform constantly lagged and caught up = visible flicker. Same root cause as the #4451 pan flicker, which only fixed the pan path and (via `isDragging` set in `onTouchStart`) the touch-pinch path; the wheel-zoom path was the only continuous gesture left with the transition on. That's why touch pinch on iPhone was smooth but trackpad pinch flickered.
-
-**Fix:** added an `isWheelZooming` state set on each `handleWheel` event and cleared on a 200ms debounce (wheel has no explicit gesture-end). Transition is `isDragging || isWheelZooming ? 'none' : 'transform 0.05s ease-out'`. Discrete zoom (buttons, double-click, keyboard) keeps the smoothing.
-
-**General pattern:** never run a CSS `transition` on a transform that's being updated by a high-frequency continuous input stream (drag, touch pinch, trackpad/`ctrl+wheel` pinch) — the interrupted-transition restart flickers. Gate the transition off for the duration of the gesture. Maintainer couldn't repro on macOS 15.6.1 (WebKit) while reporter hit it on macOS 26.5.1 / WebKit 605.1.15; the fix is version-independent.

-User report (v0.11.12 Windows): imported a folder via "Import From Directory" with **Read books in place**, later deleted the books in-app, and Readest **permanently deleted the original local files** (not even sent to Recycle Bin). Files were unrecoverable; cloud sync hadn't uploaded them yet ("Book File Not Uploaded").
-
-**Root cause:** `deleteBook` in `src/services/cloudService.ts`. For `local`/`both`/`purge`, it called `resolveBookContentSource` (`src/services/bookContent.ts`) and, when `source.kind === 'external'` (i.e. `book.filePath` set, base `'None'` — the user's own file from an in-place or transient import), unconditionally `fs.removeFile(source.path, source.base)`. `book.filePath` is set in `bookService.ts importBook` whenever `transient || inPlace`.
-
-**The trap:** this was NOT an accidental bug — it was **deliberately coded AND tested**. `cloud-service.test.ts` had a whole `in-place (book.filePath set)` describe block asserting the source file IS removed, with a comment rationalizing it as "symmetric with deleting Books/<hash>/<title>.epub for a normal book." Don't assume tested == intended; the maintainer reversed the decision.
-
-**Fix (PR #4696):** never `removeFile` an `external` source. Only `managed` sources (our Books/<hash>/ copy) and app-generated sidecars (cover.png, and the whole Books/<hash>/ dir on `purge`) are Readest's to delete. Removed the `external` branch entirely; flipped the in-place tests to assert the source is preserved (cover sidecar still removed on `both`, sidecar dir still wiped on `purge`). Also fixed the misleading JSDoc in `ImportFromFolderDialog.tsx` (`readInPlace`) that documented the destructive behavior as intended.
-
-Out of scope but noted in the support thread: deletion flow lacks a warning/disclaimer, and delete doesn't use the OS Recycle Bin. See [[bug-patterns]].

-#4773 (Android, instant highlight): highlight a word, delete it "within a very
-short time" → the mark stays painted on the page, vanishing only after reopening
-the book. Booknote IS soft-deleted (`deletedAt` set, gone on reopen) but the
-**overlay was re-drawn after removal** → orphan.
-
-**Root cause — stale memoized index re-draws a deleted annotation.**
-`Annotator.tsx` re-applies per-location annotations on every relocate via the
-memoized `annotationIndex` (`useMemo(buildAnnotationIndex(config.booknotes), [config.booknotes])`)
-→ `selectLocationAnnotations(index, location)` → `view.addAnnotation(a)`.
-`buildAnnotationIndex` filters `deletedAt` at BUILD time, but
-`selectLocationAnnotations` trusted that and did NOT re-check. The delete
-(`handleHighlight(false)`) stamps `existing.deletedAt = Date.now()` **in place**
-on the same booknote object that's still sitting in the index bucket, and
-removes the overlay (`addAnnotation(existing, true)`). If the re-apply effect
-scheduled from the popup-open render flushes AFTER the delete (the "very short
-time" window — passive effects deferred on Android WebView under rapid taps),
-`selectLocationAnnotations` returns the now-deleted object from the pre-deletion
-snapshot and `addAnnotation` re-draws it → overlay orphaned. Annotator does NOT
-re-render on booknote changes (subscribes only to the stable `getConfig` fn), so
-the memo stays stale until some other state change recomputes it.
-
-NOT instant-specific in the data layer — instant highlight (`useInstantAnnotation`)
-just makes it easy to hit (no popup friction, fast gesture). Delete + re-apply
-(where the fix lives) is shared with normal highlights. `onCreateOverlay` reads
-`getConfig` FRESH so it's safe; FoliateViewer onLoad re-draw only fires on
-section load (not a quick delete).
-
-**Fix:** re-check `deletedAt` at the READ site, not just at index build:
- `selectLocationAnnotations` (annotationIndex.ts): `if (item.deletedAt) continue;`
-  before classifying — covers both the annotations and notes lists.
- The sibling `annotationIndex.globals` loop in the Annotator re-apply effect:
-  `if (annotation.deletedAt) continue;` before `expandAllRenderedSections` (same
-  stale-snapshot hazard for global highlights).
-
-Test: `src/__tests__/utils/annotation-index.test.ts` — build index with a styled
-note, then `highlight.deletedAt = 123` in place, assert `selectLocationAnnotations`
-returns `{ annotations: [], notes: [] }` (red before fix). Verified on Xiaomi 13
-Pro (fuxi, WebView) via the CDP lane: real create→delete→immediate-relocate over
-4 iterations left overlay count 6→7→6 each time (no orphan); overlay-count metric
-proven non-blind by a stray-overlay sanity probe. See [[android-cdp-e2e-lane]].

-After the 2026-06-19 update, Android users reported tap-to-paginate failing in
-paginated mode: tapping TEXT didn't turn the page, only tapping the empty side
-MARGINS worked. Trigger = **Instant Highlight** quick action enabled (3rd toolbar
-icon / highlighter; setting = `enableAnnotationQuickActions && annotationQuickAction === 'highlight'`).
-
-**Root cause:** `useTextSelector.handlePointerDown` called `ev.preventDefault()` +
-`startInstantAnnotating()` on EVERY pointer-down over selectable text. The
-`preventDefault` suppressed the native click that drives tap-to-paginate (iframe
-`handleClick` → `iframe-single-click` → usePagination). Margins worked only because
-`handleInstantAnnotationPointerDown`→`isSelectableContent` returns false there.
-The synthetic-mousedown fallback in `handlePointerUp` is dead on Android because the
-native-touch `touchend` calls `handlePointerUp(doc, index)` with NO `ev` (Annotator.tsx
-`handleNativeTouch`), and `if (isInstantAnnotating.current && ev)` skips.
-
-**Fix (PR/commit on `dev`):** gate instant-highlight engagement behind a still hold
-for touch/pen — `INSTANT_HOLD_MS = 300`, `INSTANT_HOLD_MOVE_PX = 10` in useTextSelector.ts.
- `armInstantHold` (touch/pen) records the press, starts a 300ms timer, does NOT
-  preventDefault. A tap releases first (`handlePointerUp`/`handlePointerCancel` →
-  `cancelInstantHold`) → native click → paginate. A swipe moves first
-  (`maybeCancelInstantHoldOnMove`, called in BOTH `handlePointerMove` and
-  `handleNativeTouchMove`, compares window-coord `pointerPos` vs `instantHoldStartWindow`)
-  → native swipe → paginate. Only a still hold fires the timer → `startInstantAnnotating`.
- Mouse path unchanged (immediate `preventDefault` + start) — click vs. press-drag is
-  already unambiguous; matches the existing "mouse shouldn't be time-gated" stance.
- Refactor: `startInstantAnnotating(target, startPoint)` / `stopInstantAnnotating()` no
-  longer take `ev`; the down `target` is stored in `instantAnnotationTarget` so the exact
-  element gets `user-select` restored (pointerup target may differ after the finger moves).
-
-Two parallel instant-highlight mechanisms share the same enable flag: (1) the
-`useInstantAnnotation` live drag-to-highlight (this fix), and (2) the
-quick-action-on-selection deferred path (`beginGesture`/`deferredQuickActionRef`/
-`pointerDownTimeRef` in Annotator.tsx) which ALREADY long-press-gates touch on
-iOS/desktop but not Android. Test: `useTextSelector-instantHold.test.ts`. See
-[[keyboard-selection-adjust-4728]] for the adjacent `isPointerDown`/`handleSelectionchange` logic.

-
-Sharing a `.txt` file to Readest via the iOS share sheet got **stuck**, while EPUB/PDF worked. Root cause: the **Share Extension** (article-URL clipper, added #4256/#4267) wrongly activated for `.txt`. FIXED, **PR #4917 merged** (`fix/ios-share-txt-stuck`).
-
- `ShareViewController.swift` only ever extracts an `http(s)` URL. Its activation rule (`project.yml`) had `NSExtensionActivationSupportsWebURLWithMaxCount: 1` **and `NSExtensionActivationSupportsText: true`**.
- A `.txt` is UTI `public.plain-text`, which **conforms to `public.text`** → satisfies `SupportsText` → the URL-only clipper activates for a file it can't handle → sheet hangs (for a file-backed provider `loadItem(public.plain-text)` returns a file `URL`, so `loadText`'s `as? String`/`as? Data` both fail → no URL → neither completes nor cleanly cancels).
- EPUB (`org.idpf.epub-container`) / PDF (`com.adobe.pdf`) conform to neither text nor web-URL, so they never match the extension and take the **main app** `CFBundleDocumentTypes` "Copy to Readest" open-in-place path (`Readest_iOS/Info.plist`), which imports via `useOpenWithBooks.ts` → `importBook` (format-agnostic; txt→epub via `TxtToEpubConverter`). `.txt` is ALSO declared there, so it imports fine once the extension stops stealing it.
-
-**Fix (option A):** remove `NSExtensionActivationSupportsText: true`; keep web-URL only. Safari/Chrome "share page" still sends `public.url`, so article clipping is preserved. Only regression: sharing a raw text *selection* containing a link no longer triggers the extension (minor).
-
-**Source-of-truth gotcha:** `src-tauri/gen/apple/project.yml` is the **xcodegen** source; Tauri's iOS CLI runs `xcodegen` at build time (`tauri-cli/src/mobile/ios/project.rs`) and REGENERATES each target's `Info.plist` from it. The committed `ShareExtension/Info.plist` is a generated artifact marked **`skip-worktree`** (`git ls-files -v` → `S`) — local edits to it are invisible to git and it stays stale at HEAD. So: fix `project.yml` ONLY; a test asserting on the committed plist would pass locally but FAIL on a fresh CI checkout. Regression test lives at `src/__tests__/ios/share-extension-activation-rule.test.ts` (asserts on `project.yml`, strips `#` comments first since the warning comment names the key). Test precedent: `src/__tests__/android/*declarations*.test.ts` read native config via `resolve(process.cwd(), 'src-tauri/...')`.

-iOS reading-widget book covers sometimes showed a **bright hairline along the right edge** (Android widget never did). Fixed in PR #4950, `src-tauri/plugins/tauri-plugin-native-bridge/ios/Sources/ReadingWidgetWriter.swift` `writeThumbnail`.
-
-**Root cause:** the downsample target was fractional:
-`CGSize(width: image.size.width * scale, height: image.size.height * scale)` with `scale = 240 / longEdge`. For portrait covers the height (longEdge) lands on a whole pixel but the width is fractional. `UIGraphicsImageRenderer` allocates a **whole-pixel** buffer (rounds the size up), while `image.draw(in:)` fills only the exact fractional rect — so when the fractional width rounds *up*, the rightmost pixel column is only partially covered → **semi-transparent** (e.g. alpha 225 instead of 255). `jpegData` has no alpha, so that column flattens to a visible bright line. Intermittent ("sometimes") because it only bites when the fractional part rounds up; portrait-specific because width is the fractional edge.
-
-**Fix:** round both dimensions to whole pixels so draw-rect == pixel-buffer and every edge pixel is fully covered:
-`CGSize(width: (image.size.width * scale).rounded(), height: (image.size.height * scale).rounded())`.
-
-Verified with a faithful CoreGraphics repro (same rasterization as UIKit): `453x680` cover gave edge alpha `225` before, `255` after; all sizes `255` after. Android ([[mobile-reading-widgets]] `ReadingWidgetStore.kt`) is immune because it scales to a fixed integer 240x360 and center-crops.
-
-No checked-in Swift test: the plugin `Package.swift` has no wired test target and the code is UIKit-only.

-#4728: standard desktop selection shortcuts — `Shift+←/→` refine selection by character, `Ctrl/Alt(Option)+Shift+←/→` by word — implemented in the **parent** shortcut system, not the iframe.
-
-**Critical gotcha (cost a full redesign):** after a text selection, `Annotator.handleShowAnnotPopup` calls `containerRef.current?.focus()` on desktop, so `document.activeElement` is a **parent-document DIV**, not the book iframe. Real OS keystrokes therefore go to the parent `window` → `useShortcuts` (native keydown path) → page-turn shortcuts (`shift+ArrowRight`=`onGoNext`/`onGoForward`). A fix inside the iframe `handleKeydown` is **bypassed** for real keystrokes — it only fires if focus is in the iframe (e.g. quick-actions config). JS-dispatched `KeyboardEvent`s into the iframe doc DO hit the iframe handler, so they falsely "pass" — only a **real OS key** (`computer.key`) reveals the parent-focus path. Always verify with a real keystroke, not a synthetic dispatch.
-
-**Fix shape:**
- `utils/sel.ts`: pure `getKeyboardSelectionAdjustment(KeyModifiers)` → `{direction:'left'|'right', granularity:'character'|'word'}|null` (Shift=char, Ctrl||Alt=word, metaKey→null so native Cmd+Shift line-select survives; 'left'/'right' visual dir for RTL). `extendSelectionFromContents(contents, ev, extend)` walks `view.renderer.getContents()` (`{doc}[]`), finds the non-collapsed `doc.defaultView.getSelection()`, and (if `extend`) `sel.modify('extend', dir, gran)`; returns whether a selection was found.
- `helpers/shortcuts.ts`: new `onAdjustTextSelection` (section 'Selection') with keys `shift+Arrow{Left,Right}` + `ctrl/alt+shift+Arrow{...}`.
- `useBookShortcuts.ts`: `adjustTextSelection` wired **first** in the `useShortcuts` actions map so it intercepts before `onGoNext/Prev/...`. Native keydown (parent focus) → extend ourselves; forwarded iframe-keydown MessageEvent (iframe already extended natively) → `extend:false`, just report presence to suppress nav. Returns true ⇒ `processKeyEvent` stops ⇒ no page turn.
- `useTextSelector.handleSelectionchange`: desktop normally defers to pointerup; relaxed the gate to `!isAndroid && !isTouchInput && isPointerDown.current` (new `isPointerDown` ref set in pointerdown, cleared in pointerup/cancel) so a keyboard-driven `selectionchange` (no pointer drag) refreshes the popup/range. This realm-agnostic gate refreshes for BOTH the parent-modify and native-iframe-modify paths.
-
-**Selection.modify test artifact:** in browser-lane tests build the starting selection with `setBaseAndExtent` (or collapse+extend), NOT `addRange` — `addRange` leaves the selection directionless so backward `modify('extend','left'/'backward')` silently no-ops; `setBaseAndExtent` establishes anchor/focus like a real mouse drag.
-
-Verified live on Chrome with real keystrokes (Alice EPUB, scrolled mode): `Shift+→` "Queen"→"Queen." no turn; `Opt+Shift+→` "two"→"two miles" (word); popup follows; no selection ⇒ `Shift+→` still scrolls (nav preserved). Paginated auto-scroll-to-follow when extending past the page edge is NOT wired (foliate's `isKeyboardSelecting` scrollToAnchor only fires for iframe-focus keydowns; parent-focus has none) — minor known limitation. See [[layout-ui-fixes]].

-Issue #4751: bulk "download all" for the readest.koplugin Library view (parity with Readest web/desktop "download all"). Branch `feat/koplugin-bulk-download-4751`, PR #4765 (base main).
-
- Entry point: view-menu Actions section in `library/libraryviewmenu.lua` → calls `require("library.librarywidget").downloadAll()` (no args; reads `M._opts`/`M._store` like `M.refresh()`).
- Candidate set: new `LibraryStore:listCloudOnlyBooks()` = `cloud_present=1 AND local_present=0 AND deleted_at IS NULL AND uploaded_at IS NOT NULL` (phantom records with no uploaded file are excluded, same as `listBooks`). Whole library, ignores active search/group. Test-first in `librarystore_spec.lua`.
- Orchestration `M.downloadAll()`: sequential reuse of `syncbooks.downloadBook`, inside `Trapper:wrap`. Progress + cancel via `Trapper:info("Downloading %1 of %2…")` — it yields to UIManager, so a tap queued during the previous (blocking) download is processed at the book boundary and raises Trapper's Abort/Continue confirm (returns false → cancel). Skip per-book failures, count them, show a summary toast. Only `Trapper:clear()` when NOT cancelled (abort path already closed the widget).
- **Sync/async cb bridge** (the non-obvious bit): `downloadBook`'s callback fires exactly once but may be synchronous (token fresh) OR async (after token refresh). In the cb, resume the coroutine only `if coroutine.status(co) == "suspended"`; capture result + a `finished` flag, and only `coroutine.yield()` `if not finished`. This avoids "resume non-suspended coroutine" errors in the sync case and correctly awaits in the async case. Reusable for any callback-style KOReader API awaited inside a Trapper coroutine.
- i18n: 6 new `_()` strings, `T(_("… %1 …"), ...)` interpolation (`local T = require("ffi/util").template`). Ran `node scripts/extract-i18n.js`; translated all 33 locales via [[i18n-koplugin]] flow. Verify: placeholders `%1/%2/%3` preserved (no `%s/%d`), `…` U+2026 kept.
- Note: the per-book long-press sheet already had a "Download All" (cover+file for ONE book) — left as-is; distinct from the new bulk "Download all books".
-
-Gates: `pnpm lint:lua` + `pnpm test:lua` (see [[verify-format-check-gate]] / verification.md). No JS/TS/Rust changes.

-Issue #4954 (PR #4974, MERGED 2026-07-07): opening the KOReader plugin Library
-was slow on large libraries (~1000 books) while navigation stayed fast.
-
-**Root cause (measured, not guessed).** Added open-path timing instrumentation
-(`ui/time` + `elapsed_ms` helper) to `library/librarywidget.lua` (initial
-`build_item_table`, `lightScan`, post-scan refresh, total synchronous open,
-cloud-sync elapsed) and a step breakdown in `library/localscanner.lua`. On a
-685-book library the synchronous open was ~300ms, dominated by a **254ms
-post-scan refresh** = `library/group_covers.lua` recomposing each folder's 2x2
-cover **mosaic from scratch on every paint** (up to 4 MuPDF decodes+scales per
-cell), with no cache, and again on the post-sync refresh. `build_item_table`
-(7ms) and `lightScan` (28ms, only 16 sidecar reads) were NOT the bottleneck —
-my initial hypotheses (defer lightScan / incremental history) were refuted by
-the log. Why "slow to load, fast to navigate": the root Groups view is mosaics;
-drilling into a group shows single covers (cheap, BIM-cached). Soft-scales with
-size (fuller groups → 4 covers/mosaic vs 1). Data-side pagination is NOT
-possible (KOReader `Menu` derives page count from `#item_table`).
-
-**Fix (mirror `cloud_covers` async pattern in `group_covers`).**
- Cache composed master bb per group, keyed by `mosaic_cache_key` = ordered
-  child hashes + a per-child **cover-availability bit** (`child_cover_available`
-  → `cloud_covers.cover_exists(hash)` or local file stat). Serve `copy_bb` on
-  hit. The availability bit fixes the historical "partial composite served
-  forever" bug that killed the prior on-disk cache: a late cover flips the key
-  and recomposes once.
- **Cache the `nil` result too** (critical): a coverless group whose children
-  aren't downloaded makes `compose` return nil; if not cached it re-enqueues +
-  `schedule_refresh` on every refresh → infinite recompose/refresh loop (eink
-  flashing). Caught this in the second emulator log (`group_nameLanguagegrid`
-  missing every refresh). Cache nil under the availability key → placeholder
-  served, no re-enqueue.
- Compose off first-paint: miss enqueues a single-slot background job (one
-  mosaic per UI `nextTick`, `_pump_scheduled` coalesces), returns nil so the
-  cell paints its FakeCover placeholder; completions coalesce into one refresh.
- `clear_cache()` on Library close (via `libraryitem.set_visible_hashes(nil)`)
-  frees masters (~0.7MB each).
-
-Result: synchronous open 300ms→151ms, post-scan refresh 254ms→89ms (now just the
-4 visible single cloud-book cover decodes + placeholders, mosaics deferred).
-
-**Left out (follow-ups noted in PR):** single cloud-book covers
-(`cloud_covers.load_cover_bb`) still re-decode from disk each refresh (~89ms/4)
-— same copy-on-serve cache could apply; deferred cloud sync uses synchronous
-HTTP that briefly freezes UI after the menu appears (elapsed 1.6-6.8s, network
-variance). Instrumentation kept intentionally (Library open is infrequent).

-description: "#4934 koplugin Library goes stale forever: pull cursor keyed on client updated_at not server synced_at; split pull/push cursors + v2->v3 heal migration"
-metadata:

---
-
-**Issue #4934, PR #4944 MERGED** (merge commit `0b180da6a`, koplugin Lua only, base `readest/readest:main`). Reporter: iOS + KOReader; the koplugin "Readest library" stopped receiving iOS updates and never recovered. Workaround was delete `koreader/settings/readest_library.sqlite3` + "Pull books now" (works for a while, re-breaks). **iOS/web library unaffected** — the smoking gun.
-
-**Root cause (the direct follow-up [[sync-synced-at-cursor-4678]] predicted).** Since #4678 the server keys the books GET on the server-stamped `synced_at` (`src/pages/api/sync.ts` `cursorColumn = table==='books' ? 'synced_at' : 'updated_at'`, `.gt('synced_at', since)`). Web/iOS advance their cursor from `synced_at` (`useSync.ts computeMaxTimestamp`, prefers synced_at) → always ≤ server-now → never stale. The **koplugin was left on `updated_at`**: `syncbooks.lua pullBooks` set `last_books_pulled_at = max(updated_at, deleted_at)` of returned rows; `parseSyncRow` never read `synced_at`. `updated_at` is CLIENT event time, and the koplugin stamps it from the **device clock** (`librarystore.lua touchBook` = `os.time()*1000`). An e-reader clock ahead of the server (common; dead RTC / wrong date) — or ANY single row account-wide carrying a future `updated_at` — drove the koplugin's global cursor past server-now, so `synced_at > since` returned nothing **forever**. Delete-sqlite reset the cursor to 0 (workaround); it re-broke once a book-open re-bumped it into the future.
-
-**Extra hazard #4678 flagged:** `last_books_pulled_at` was SHARED between the pull cursor (vs server synced_at) and push-delta detection (`getChangedBooks` vs LOCAL updated_at) — can't just retarget it to synced_at. So the fix requires a cursor SPLIT.
-
-**Fix (all in `apps/readest.koplugin/library/`):**
-1. `librarystore.lua parseSyncRow`: add transient `synced_at = iso_to_ms(dbRow.synced_at)` (NOT a books column; server sends it via `select('*')`). New `getLastPushedAt`/`setLastPushedAt` on key `last_books_pushed_at`.
-2. `syncbooks.lua`: new pure `row_pull_cursor(parsed)` = `parsed.synced_at` if present else `max(updated_at, deleted_at)` (mirrors computeMaxTimestamp; exported `M._row_pull_cursor` for tests). `pullBooks` seeds `pull_ts`/`push_ts` from their stored values (no regression on empty pages), advances `last_books_pulled_at` from `row_pull_cursor` (synced_at) and `last_books_pushed_at` from `max(updated_at, deleted_at)` of pulled rows. `pushChangedBooks` reads/writes `getLastPushedAt`/`setLastPushedAt` instead of the pull cursor.
-3. **Cursor split:** pull cursor = server `synced_at` (pull only); push watermark = local `updated_at`, advanced on BOTH pull and push (preserves the old dedup so pulled books aren't re-pushed — the old shared cursor did exactly this).
-4. **Heal migration `SCHEMA_VERSION 2->3`** (`M.new`, guard `prev>=1 and prev<3`): `INSERT last_books_pushed_at SELECT value FROM ... WHERE key='last_books_pulled_at'` then `UPDATE ... SET value='0' WHERE key='last_books_pulled_at'`. Seeds push watermark from the old shared value (no re-push storm) and zeroes the pull cursor → next sync does ONE full re-pull that re-establishes it on synced_at. **Auto-heals already-stale installs; user need not delete the sqlite.**
-
-**Scope note (intentional):** the push watermark, seeded from a poisoned future value, still suppresses the koplugin's OWN local pushes until wall-clock passes it — but that's UNCHANGED from before (old shared cursor did the same) and #4934 is a pull/viewing bug ("iOS unaffected"). Not fixing device-clock `updated_at` here. Only functional cursor callers are in syncbooks; `librarywidget.lua:557` only logs it.
-
-**Tests (TDD, gates `pnpm test:lua` 224✓ / `pnpm lint:lua` exit 0):** `librarystore_spec.lua` — parseSyncRow synced_at, getLast/setLastPushedAt independent round-trip, `v2->v3 migration` (reset pull=0 + seed push, per-user), bumped user_version 2→3 (and the v1->v2 test now lands at 3, migrations cumulative). `syncbooks_spec.lua` — `_row_pull_cursor` (synced_at wins over a future updated_at; fallback; 0), and `pullBooks` integration via injected fake `sync_auth`/client + real in-memory store asserting pull cursor=synced_at (not future updated_at) and push watermark=updated_at distinctly.

-#4692 (PR #4711): KOReader Sync to a self-hosted Grimmory/Booklore server failed on Android (worked on iOS). Root cause was a **misconfigured Server URL** that resolved to the host's static web UI instead of the sync endpoint, made undebuggable by a Readest gap.
-
-**Server-side tell (the smoking gun):** Android `PUT /syncs/progress` was handled by Spring's `ResourceHttpRequestHandler` → `HttpRequestMethodNotSupportedException: Request method 'PUT' is not supported`. That handler is Booklore's SPA/static fallback — so the request reached the server but **missed the koreader controller** and hit the catch-all static handler. GET requests (auth/pull) silently get the HTML index with 200; only PUT errors (static handler rejects non-GET/HEAD).
-
-**Readest gap:** `KOSyncClient.connect()` treated any 2xx from `/users/auth` (or `/users/create`) as success. An HTML web-UI page returns 200 → false-positive "connected"; then pulls show 0% and pushes fail with no error surfaced. Matches the classic "no errors reported, still 0%" report.
-
-**Fix:** validate the auth/registration response is an actual koreader JSON object (real server → `{"authorized":"OK"}`; HTML fails `response.json()`), else return "Not a KOReader Sync server. Check the Server URL." (`isKoSyncJsonResponse` helper in `KOSyncClient.ts`). Catches misconfig at setup, when actionable.
-
-**Still silent (intentional follow-up, not done):** per-sync push/pull failures. `getProgress`/`updateProgress` collapse "request failed" and "no remote data" into the same `null`/`false`; naive toasting would fire on every transient auto-push (5s). Needs noise-aware design before surfacing.
-
-KOSync settings are **per-device** (no Readest account → not synced across devices), so iOS vs Android URLs are entered independently — the #1 suspect when one platform syncs and the other doesn't. Related: [[kosync-cfi-spine-resolution]], [[empty-start-cfi-sync]].

-#4743: library and reader shared one background texture; split so each is set independently.
-
-**Architecture**: ONE global `<style id="background-texture">` paints `body::before` (covers library) plus reader containers (`.foliate-viewer/.sidebar-container/.notebook-container ::before`). Library and reader are separate routes (only one mounted), so the split = store two values + have each page apply its own on activation, not separate style elements. New device-local `SystemSettings.libraryBackground{TextureId,Opacity,Size}` (NOT in settings sync whitelist — texture *selection* is per-device like reader's `backgroundTextureId`; only image binaries sync via `texture` replica kind). `getLibraryViewSettings(settings)` in `helpers/settings.ts` resolves each field with `?? globalViewSettings.<field>` so the bookshelf inherits the reader texture until decoupled (no migration). `ColorPanel` is context-aware via `isLibraryContext = !bookKey`: library context writes `libraryBackground*` via `saveSysSettings`, reader context unchanged via `saveViewSettings`. Applied at boot (`Providers`) + on every library mount (`library/page.tsx` effect).
-ThemePanel
-**Gotcha 1 — `useBackgroundTexture` early-returned on `'none'` WITHOUT unmounting.** Since library+reader share the one style element, switching a page to None must actively clear a texture the OTHER page mounted. Fixed: always delegate to `applyTexture(envConfig, textureId || 'none')` (it unmounts on 'none'); only set CSS vars / addTexture for a real texture. Also fixes the symmetric reader case (opening a 'none' book after a textured one).
-
-**Gotcha 2 — `useSettingsStore` initializes `settings: {} as SystemSettings`.** So `settings.globalViewSettings` is `undefined` on the first renders before `appService.loadSettings()` runs. Any NEW effect/deps that deep-derefs `settings.globalViewSettings.<x>` crashes the library with "Cannot read properties of undefined (reading 'backgroundTextureId')". Caught only in a hard reload (HMR kept old store state, so first nav didn't repro). Fix = optional-chain in effect deps + make the resolver tolerate missing globalViewSettings (fallback to 'none'). Relates to [[cover-stale-inplace-mutation-memo]].
-
-Verified end-to-end in dev-web: library moon texture, reader stays none, round-trip persists, None clears live. Related: [[wordlens-feature]] i18n (recent feature commits ship `_()` strings WITHOUT running `i18n:extract`; translations are batched separately — don't commit locale churn in a feature PR).

-PR #4799 (branch `fix/list-series-overflow-4796`). Reported on Pixel 10 Pro / Android 16: in library **list view**, a book that belongs to a series shows its series line and description preview overlapping and cut off.
-
-**Root cause:** `BookItem.tsx` list-mode container used a fixed `h-28` (112px) with `overflow-hidden`. The right column stacks title + authors + (optional) series + description + a progress/actions row (`useResponsiveSize(15)` → ~19px on phones). Without a series it fits 112px; the optional series line (added in #4593/#4612) pushes the total over 112px, so the lines collide and clip. **Android applies the system accessibility font-size scale to WebView CSS text**, inflating line heights — that's what made it bad enough to report (matched the issue screenshot at ~130% scale).
-
-**Fix:** `h-28` → `min-h-28` (one class). Row grows to fit; non-series rows keep 112px. List is `Virtuoso` with measured (not fixed) heights, so variable row heights are fine.
-
-**Verification:** jsdom can't measure layout, so reproduced the exact flex markup in a real browser at normal + 130% font scale (before = overlap, after = clean). Lint + full `pnpm test` (6324 pass) + `format:check` pass.
-
-Lesson: fixed-height list/card rows are fragile against optional metadata lines AND user font scaling. Prefer `min-h-*` when the row can virtualize. Related: [[cover-stale-inplace-mutation-memo]].

-Issue #774: render standalone `.md` files at runtime (NO EPUB conversion). **MERGED as
-PR #4816** (branch `feat/markdown-support`). Built test-first via `/autoplan` (CEO+Eng
-dual-voice review). Suite green (6365), lint + format clean; live-verified in web app
-(import via drop, split TOC, cross-section nav, GFM rendering, pagination).
-
-**Where:** `src/utils/md.ts` `makeMarkdownBook(file)` builds an in-memory foliate book
-modeled on `packages/foliate-js/fb2.js`. Routed in `src/libs/document.ts` `open()` via
-`isMd()` **before `isTxt()`** (a `.md` served as `text/plain` would otherwise hit TXT→EPUB).
-`'md'` added to `SUPPORTED_BOOK_EXTS` (constants.ts). `sanitize.ts` `sanitizeHtml` gained
-`'class'` (code `language-*` theming) + `del`/`ins` tags. Pipeline: strip YAML frontmatter →
-`marked`(gfm) → `sanitizeHtml` → split at `<h1>` (preamble = pre-first-H1 content) → nested
-heading-outline TOC.
-
-**Non-obvious foliate book-object contract (cost us the CRITICAL review finding):**
- `section.id` and `splitTOCHref()` output MUST be the SAME type. readest nav
-  (`services/nav/index.ts:133`) does `new Map(sections.map(s=>[s.id,s]))` then `.get(sectionId)`
-  where sectionId = `splitTOCHref(href)[0]`. `SectionItem.id` is typed `string`, so use
-  STRING ids + `splitTOCHref => href.split('#')`. fb2.js uses numbers consistently (works
-  only because it's untyped JS); do NOT copy fb2's `Number(x)`.
- Fragment CFIs / TOC sub-anchors require `section.loadText` (nav skips sections without it,
-  index.ts:153). Provide it.
- `SectionItem.cfi` is non-optional → set `cfi: ''` (foliate falls back to `CFI.fake.fromIndex`).
- `createDocument()` parses `application/xhtml+xml`; marked's HTML5 void tags (`<br><hr><img>`)
-  are parse errors there → serialize sections with `XMLSerializer` (not innerHTML). `load()`
-  and `createDocument()` must derive from the SAME string (CFI round-trip).
- `resolveHref` returns `null` for unresolved anchors (never index 0). jsdom lacks
-  `URL.createObjectURL` → `load()` is lazy + tests stub it.
-
-**Deferred follow-ups (open issues):** relative image resolution (web File-objects have no
-sibling access — needs the bundle model); Markdown folder/zip "package" model; footnotes/math/
-Mermaid/wikilinks; syntax-highlight token colors. Plan: `.claude/plans/2026-06-26-markdown-md-support-774.md`.

-Middle mouse button autoscroll for desktop Tauri apps in scrolled mode
-(readest#4951), PR #4955 MERGED 2026-07-06 (merge 6f3b401c2). No settings
-toggle: always on for desktop in scrolled mode (maintainer removed the toggle
-as unnecessary; middle click has no other use in the reader). The same PR also
-shipped a locale sync: 69 keys untranslated on main filled across 33 locales
-(agents per language family; scanner-prunable keys preserved).
-
-Key structure:
- `src/app/reader/utils/autoscroller.ts` — pure `Autoscroller` class (RAF loop,
-  12px dead zone, 10 px/s per px linear velocity capped 4000, whole-pixel
-  emission with fractional carry, held→sticky/drag state machine). Tested in
-  `src/__tests__/reader/utils/autoscroller.test.ts` with injected raf/now.
- `useMiddleClickAutoscroll(bookKey, viewRef, containerRef)` hook consumes
-  `iframe-mousedown/mouseup/mousemove/wheel/keydown` messages + window-level
-  capture listeners; returns anchor (container-relative) for
-  `AutoscrollIndicator`. Scrolls with `renderer.containerPosition += delta`
-  (public setter; native scroll path, so section preloading works). Axis from
-  `renderer.scrollProp` ('scrollLeft' = vertical writing → x axis; increasing
-  scrollLeft always moves viewport right even in RTL, no special-casing).
- iframeEventHandlers runs in the parent realm: `setAutoscrollArmed(bookKey)`
-  registry lets `handleMousedown` preventDefault middle button (suppresses
-  WebView2's native autoscroll on Windows, avoids double-drive) and
-  `handleAuxclick` swallow link opens; `setAutoscrollTracking(bool)` gates an
-  `iframe-mousemove` postMessage forwarder so it costs nothing when idle.
- Pointer deltas use screenX/Y (same trick as useTouchEvent pinch) so iframe
-  coordinate spaces/transforms don't matter. Anchor window position computed in
-  the iframe handler via `event.view.frameElement.getBoundingClientRect()` +
-  client-size scale, posted as windowX/windowY on button-1 mousedown only.
- A left click that ends a sticky session must not also turn the page: the
-  hook consumes the later `iframe-single-click` via
-  `eventDispatcher.onSync` within a 500ms window (usePagination checks
-  dispatchSync consumption before paginating).
- Setting `middleClickAutoscroll` in `BookLayout` (default TRUE, user chose
-  default-on), toggle in ControlPanel Scroll BoxedList, desktop only
-  (`appService?.isDesktopApp`), disabled unless scrolled mode. Web excluded on
-  purpose (browsers own middle click).
-
-Related: [[i18n-extract-prunes-keys]] (followed its manual single-key insertion
-recipe for the 'Middle-Click Autoscroll' label across 33 locales).

-Mobile home-screen reading widgets (issue #1602, merged PR #4842). Code lives in the **native-bridge plugin**: `src-tauri/plugins/tauri-plugin-native-bridge/{android,ios}/` (Android `ReadingWidgetProvider.kt` + `res/`; iOS writer `ReadingWidgetWriter.swift`) and the iOS WidgetKit extension at `src-tauri/gen/apple/ReadestWidget/`. App publishes a snapshot + downsized cover thumbnails via the `update_reading_widget` command to iOS App Group `group.com.bilingify.readest` / Android `SharedPreferences`. Widget hook: `src/hooks/useReadingWidget.ts`; payload builder `src/services/widget/readingWidget.ts`; tap opens `readest://book/{hash}` via `useOpenBookLink.ts`.
-
-Durable, non-obvious gotchas (each cost a debugging round):
-
- **iOS widget missing from gallery = stale `.xcodeproj`.** `gen/apple/project.yml` defines the `ReadestWidget` target, but **Tauri's iOS build does NOT re-run xcodegen**, so a newly-added target is silently omitted from the build. Fix: `cd src-tauri/gen/apple && xcodegen generate`. Also: iOS builds from the **MAIN repo** `/Users/chrox/dev/readest` (complete gen/apple), NOT the `pnpm worktree:new` worktree (its gen/apple is incomplete — missing `Sources/`, `Assets.xcassets`, `Externals`, `LaunchScreen.storyboard` — so xcodegen fails there).
- **Android RemoteViews allow only @RemoteView widgets.** Plain `<View>` (and `<Space>`) is NOT allowed → launcher inflate fails → "Can't load widget". Use an empty `FrameLayout` for spacers. Covers: badge + progress bar are **baked into the bitmap** (Canvas in `writeThumbnail`) because RemoteViews can't clip/overlay reliably; shown via `fitCenter`. Responsive sizing by grid cells: `n = (minWidthDp + 30) / 70` (Android cell formula); one book per column, cap 3.
- **Background TTS progress freeze.** `book.progress` (libraryStore) AND `readerProgressStore` are both written by the same `setProgress`, inside `commitRelocate` → **`requestAnimationFrame`**, which Android pauses for a backgrounded WebView → both freeze during background TTS. No store-only fix (page-based progress needs rendering). Fix: in `FoliateViewer.progressRelocateHandler`, commit synchronously when `document.visibilityState === 'hidden'` (relocate still fires; only the rAF commit was deferred). Confirmed working on device.
- **Android crash: "cannot use a recycled source in createBitmap" (exact-2:3 covers).** In `ReadingWidgetStore.writeThumbnail`, `Bitmap.createBitmap(src, x, y, w, h)` returns the SAME instance when the crop covers the whole *immutable* source (`decodeFile` bitmaps are immutable) — which happens when the cover decodes to exactly 2:3 (height==width*3/2), making the center-crop a no-op. The old code then did `bitmap.recycle()`, recycling `cropped` too, so the next `createScaledBitmap(cropped, …)` threw. Fix: `if (cropped !== bitmap) bitmap.recycle()` — mirror the `if (scaled !== cropped) cropped.recycle()` guard already 4 lines below. Trace was R8-obfuscated + ran inside `update_reading_widget`'s `pluginScope.launch { withContext(Dispatchers.IO) }`, surfacing as `FATAL EXCEPTION: main` with a `Dispatchers.Main` cancelled-coroutine suppressed frame. **iOS is unaffected** — `ReadingWidgetWriter.writeThumbnail` uses ARC-managed immutable `UIImage` + `UIGraphicsImageRenderer`, no manual recycle/aliasing.
- **iOS TTS controls deferred** — interactive widget buttons need iOS 17 App Intents; widget min target is iOS 15 (15/16 widgets can only deep-link, no buttons). Android uses `MediaButtonReceiver.buildMediaButtonPendingIntent` (any version). Follow-up only.
- **`.superpowers/` is NOT gitignored** in this repo → a subagent's `git add` can sweep SDD scratch (`*-report.md`) into a commit; check `git ls-files '.superpowers/*'` before squashing/pushing.

-Issue #4580 (fix: PR #4803, branch `fix/multiwindow-settings-revert-4580`): on desktop (Tauri) global view settings (Click/Swipe to Paginate, Show Page Navigation Buttons) "revert to default" — only when multiple windows are open (OP ran `1 + n_opened_books` windows).
-
-**Root cause:** each Tauri window keeps its own in-memory `useSettingsStore.settings`, loaded once at window open. Global settings persist to ONE shared `settings.json`, and every window writes the WHOLE object via the store's `saveSettings`. A window opened before the user customized a global setting holds the default (e.g. `disableClick=false`); when it later saves (notably `handleCloseBooks` on reader-window close in `ReaderContent.tsx`, but ANY settings write) it clobbers the user's value back to default. Explains "reverts to *default*, only with multiple windows". Note: `replicaCursorStore` avoids this by load-modify-saving from disk each time.
-
-**Fix:** cross-window broadcast. `src/utils/settingsSync.ts` (`broadcastGlobalSettings` emits `global-settings-window-sync` with `sourceLabel` + the two global blobs; `subscribeSettingsSync` ignores self; `mergeSyncedGlobalSettings` adopts `globalViewSettings`/`globalReadSettings` and preserves all device/window-local fields). Store `saveSettings` calls `broadcastGlobalSettings` after persisting. `useSettingsSync` (mounted in `Providers.tsx`, the shared root for both library + reader windows) adopts broadcasts via `setSettings`. No-op off Tauri.
-
-Only the two global objects are synced (minimal scope) — covers the reported bug + sibling read settings; top-level scalars left window-local. No save/broadcast loop: receive calls `setSettings` only; the replica publisher subscriber pushes to network (no disk write) and pagination fields aren't in `SETTINGS_WHITELIST` anyway. Live cross-window view update of already-open books is intentionally NOT done (bug is persistence, not live propagation). Related: [[webdav-connect-nullified-4780]] (stale settings closure), [[window-state-sanitize-4398]].

-# Native local iOS TTS (#4676)
-
-STATUS: MERGED (PR #4697, into main 2026-06-21). Device-verified by maintainer:
-system-voice playback, voice selection, rate/pitch, auto-advance, pause/resume,
-stop/disable teardown, and lock-screen controls + metadata for both system and
-Edge TTS. Final design = iOS lock screen via `navigator.mediaSession` (NOT the
-native plugin); the Swift media-session methods are dead on iOS (Android-only).
-Diagnostic logging was stripped before merge.
-
-Goal: give iOS the same on-device TTS Android has (private, offline). The shared
-TypeScript `NativeTTSClient` (`src/services/tts/NativeTTSClient.ts`) and the Rust
-command/mobile layer (`src-tauri/plugins/tauri-plugin-native-tts/src/{commands,mobile,models}.rs`)
-were already platform-agnostic — only the Swift plugin (a `ping()` stub) and two
-gates were missing. See [[tts-fixes]].
-
-## What was changed
- **`ios/Sources/NativeTTSPlugin.swift`** — full impl mirroring `android/.../NativeTTSPlugin.kt`.
-  Commands: init, speak, stop, pause, resume, set_rate, set_pitch, set_voice,
-  get_all_voices, set_media_session_active, update_media_session_state,
-  update_media_session_metadata, checkPermissions/requestPermissions.
- **`TTSController.ts:91`** gate: `isAndroidApp` → `isAndroidApp || isIOSApp` (creates `ttsNativeClient`).
- **`mediaSession.ts` `getMediaSession()`** reorder: check native platforms FIRST
-  (`(android||ios) && isTauriAppPlatform()` → `TauriMediaSession`), THEN
-  `'mediaSession' in navigator`. iOS WKWebView (and Android WebView) expose
-  `navigator.mediaSession`, but the web session can't drive lock-screen controls
-  for AVSpeech/TextToSpeech — so it must lose to the native plugin.
- Tests: `tts-controller.test.ts` iOS gate + new `__tests__/libs/mediaSession.test.ts`.
-
-## Non-obvious gotchas
- **`init` is a Swift reserved word.** Tauri iOS dispatch = `perform(Selector("\(command):"))`
-  (`mobile/ios-api/.../Tauri.swift`), so the "init" command needs selector `init:`.
-  Solution: `@objc(init:) public func initialize(_ invoke: Invoke)`. Verified it
-  compiles + `responds(to: Selector("init:"))==true` via swiftc. `perform` doesn't
-  apply ARC init-family retain rules (those are compile-time, direct-send only).
-  If it ever misbehaves on-device, fallback = rename the command for iOS in `mobile.rs`.
- **Pause == stop (mirror Android).** JS `NativeTTSClient.pause()` returns `false`,
-  so `TTSController.pause()` (line 472) does stop + re-speak on resume. The Swift
-  delegate must emit `end` ONLY on `didFinish`, **never on `didCancel`** (cancel
-  comes from stop/pause; an `end` there would auto-advance the reader).
- **AVAudioSession is owned by native-bridge.** `useTTSControl` calls
-  `invokeUseBackgroundAudio({enabled})` (plugin:native-bridge|use_background_audio →
-  `.playback`) on iOS TTS start/stop. AVSpeechSynthesizer uses the app session
-  (`usesApplicationAudioSession` defaults true), so the native-tts plugin does NOT
-  touch the audio session. Background + silent-switch playback comes for free
-  (Info.plist already declares `UIBackgroundModes: [audio]`).
- **MPRemoteCommandCenter.shared() is app-global and shared** with native-bridge's
-  `MediaKeyHandler` (hardware media-key page-turns on next/previousTrack). The
-  native-tts plugin stores its `addTarget` tokens and removes ONLY those on
-  deactivate. Lock-screen next/previous + the media-key page-turn both fire if
-  both are active — on-device test point.
- **Rate curve.** JS sends `pow(userRate, 2.5)` (tuned for Android setSpeechRate,
-  1.0=normal). Swift `avRate()` inverts (`^(1/2.5)`) and rescales onto
-  AVSpeechUtterance (0…1, `AVSpeechUtteranceDefaultSpeechRate`≈0.5 = normal). Top
-  speeds saturate at max (AV limitation).
- Voice id = `AVSpeechSynthesisVoice.identifier` (round-trips through set_voice →
-  `AVSpeechSynthesisVoice(identifier:)`). All iOS voices group under "System TTS"
-  in the JS `getVoices` (no `_`-prefixed engine id); enhanced/premium quality
-  appended to the display name to disambiguate same-named variants.
- Permissions already granted: `native-tts:default` (no platform restriction in
-  `capabilities/default.json`) covers every command.
-
-## Media session on iOS — REVERTED the native reroute (round 3)
- On-device trace confirmed parallel teardown WORKS (`stop: wasSpeaking=true stopSpeaking returned true` → `set_media_session_active active=false` → `deactivateRemoteCommands: removed 5 targets, cleared nowPlayingInfo`). The remaining media-session problems were caused by the `getMediaSession()` reroute itself:
-  - Edge TTS lock screen lost cover + current sentence (REGRESSION): Edge plays via a WebView `<audio>` element → its lock-screen card is driven by `navigator.mediaSession.metadata` (set in `useTTSControl`). Routing iOS to `TauriMediaSession`/`MPNowPlayingInfoCenter` bypassed that.
-  - System TTS got NO controls: `AVSpeechSynthesizer` is not a WebView media element, so the app never becomes "Now Playing" and the plugin's `MPRemoteCommandCenter` targets never surface. (Edge gets controls because its `<audio>` element makes the app now-playing.)
- FIX: `getMediaSession()` reverted so iOS uses `navigator.mediaSession` (Android still first→`TauriMediaSession` foreground service). iOS system TTS now rides the same WebView path as Edge — the silent keep-alive `unblockAudio` `<audio>` element + `navigator.mediaSession` metadata/action-handlers. OPEN/UNVERIFIED: whether the SILENT keep-alive element registers as Now Playing on iOS (if not, system TTS still shows no card — would need a non-silent keep-alive or a real native now-playing implementation). The iOS Swift media-session methods (set_media_session_active etc.) are now DEAD on iOS (only Android Kotlin uses them via TauriMediaSession); left in place, harmless.
- Heavy Swift diagnostic logging (per-voice dump + per-command enter/resolve + delegate) still present; trim once confirmed.
-
-## Follow-up iOS fixes (same PR)
- **Duplicate voice names**: Eloquence + legacy "novelty" voices (Rocko, Shelley, Grandma, Grandpa, Eddy, Reed, Flo, Sandy…) ship in many regions of one language, all quality=default. JS `getVoices` groups by primary language (`isSameLang`→normalized subtag), so e.g. en-US "Rocko" + en-GB "Rocko" collide in one "System TTS" list. Fix (in Swift `get_all_voices`): count `(primaryLanguage, displayName)`; for collisions append `regionDescription` (localized region, e.g. "Rocko (United Kingdom)"). Unique names stay clean. 192 system voices on a loaded device.
- **First word clipped "sometimes"**: each sentence is a separate `AVSpeechUtterance` spoken after a gap → audio route goes cold between sentences → first phonemes clipped. Same family as the startup `!act` (cannotActivate) `AVAudioSession` error from native-bridge `use_background_audio`. Fix: `utterance.preUtteranceDelay = 0.1` warms the route with silence first.
- **Stop "never tears down" / TTS icon stays blue (native only, Edge fine)**: the icon's blue state is driven by `viewState.ttsEnabled` (footer toggle) AND `isPlaying`/`showIndicator` (floating gradient `TTSIcon`). `handleStop` (useTTSControl) did all of `setIsPlaying`/`showIndicator` THEN `await ttsController.shutdown()` THEN `setTTSEnabled(bookKey,false)` as the LAST line — with NO try/catch. So if native `shutdown()` hangs OR throws, `setTTSEnabled(false)` never runs → footer icon stays blue forever; Edge never hits the stalling native path. ROOT FIX = reset ALL UI/session state (incl. `setTTSEnabled(false)`, null the ref) UP FRONT, then run shutdown/deinit best-effort in try/catch. Couldn't statically prove the exact native hang (every await in shutdown→stop is bounded/resolvable; native stop resolves since set_voice/set_rate use the same `resolve()` and playback works), so ALSO: bounded native stop invoke in `NativeTTSClient.stop()` (1500ms `Promise.race`) + Swift `os.Logger` lifecycle traces (speak/stop/pause/didStart/didFinish/didCancel) to pinpoint on-device — tapping stop should log `stop: requested`→`stop: resolved` + `didCancel`. Guard tests in `useTTSControl.test.tsx` assert `setTTSEnabled(false)` runs even when `shutdown()` rejects/never-resolves. NOTE: web bundle must be rebuilt for these JS fixes (not just the Swift plugin).
- **Lock-screen media session keeps running after disable (native only) — round 2**: the icon fix moved `setTTSEnabled` early, but `deinitMediaSession()` + `invokeUseBackgroundAudio({enabled:false})` were STILL after `await ttsController.shutdown()`. Native `shutdown()` stalls → those never run → lock-screen Now Playing lingers (Edge unaffected: never hits the stalling native path). The Swift media-session teardown is correct (Edge proves `set_media_session_active(false)`→`deactivateRemoteCommands` clears `MPNowPlayingInfoCenter.nowPlayingInfo`) — it just wasn't being CALLED. FIX = run shutdown + `invokeUseBackgroundAudio(false)` + `deinitMediaSession()` via `Promise.all` (best-effort, parallel) so media/audio teardown never waits on the controller shutdown. Added `set_media_session_active` os_log + guard test (deinit called even when shutdown never resolves). Still UNCONFIRMED why native `shutdown()` itself stalls (all JS awaits bounded; native stop invoke should resolve) — Swift lifecycle logs will reveal on-device.
-
-## Verification done / pending
- Done (host): `pnpm lint`, `pnpm test` (only pre-existing unrelated
-  `fixed-layout-paginated-scroll.test.ts` fails — untracked, no impl), swiftc
-  `-typecheck` of the plugin vs iOS SDK with Tauri stubs (0 errors; Sendable
-  warning is a standalone-swiftc strict-concurrency artifact, project is Swift 5).
- Pending (on-device, user): build iOS, confirm init/speak/voices/rate/pitch,
-  auto-advance, pause-resume, lock-screen play/pause/next/prev + now-playing,
-  background playback, and the MediaKeyHandler interaction.

-# Native System TTS offline auto-advance halt (#4613, #4408)
-
-**Symptom:** With Android System TTS (or iOS) **offline**, read-aloud stops — #4613 "at the end of the chapter, won't go to next chapter" (Samsung S25, Chinese voices); #4408 "random intervals" (GrapheneOS, Supertonic engine). Then the play/headphone controls feel **wedged**; #4408 also flashes the "Please log in to use advanced TTS features" toast on manual restart (separate client-selection path — controller briefly tries Edge).
-
-**Root cause (`TTSController.#speak`):** auto-advance fires ONLY on `lastCode === 'end'`. The native client surfaces an offline engine failure as a terminal **`'error'`** code (Android `UtteranceProgressListener.onError`). Usually a **specific unsynthesizable utterance** (an unsupported CHARACTER — chrox's insight, fits online/offline asymmetry: engines network-fall-back for hard chars when online), hit on the new chapter's first utterance. On `'error'`: no `forward()` → playback dead-ends; `this.state` stays `'playing'` → controls wedge (restart re-errors on the same chunk). Edge/Web throw instead (caught by `error()` → state 'stopped'), so only **native** hits this. Engine-specific: Google local voices emit `onDone` fine, so it doesn't reproduce on every device.
-
-**Fix (PR #4716, `#speak` only):** gate `canSkipOnError = this.ttsClient === this.ttsNativeClient`. On terminal `'error'` (native, playing, !aborted, !oneTime): **SKIP the chunk and `forward()`** — same as `'end'` — because re-speaking deterministically-bad text just fails again (do NOT retry; first attempt was retry-the-same-chunk which is futile for an unspeakable char). Bound `#consecutiveSpeakErrors` (reset on `'end'`); when it exceeds `TTS_NATIVE_SPEAK_MAX_CONSECUTIVE_ERRORS=5` → `await this.stop()` (graceful: wholly-unusable engine stops instead of silently racing to book end; leaves 'playing' so controls recover). Edge/Web byte-for-byte unchanged. Tests (`tts-controller.test.ts` "native TTS offline error recovery (#4613, #4408)"): skip-advances-past-bad-chunk (forward spied) + cap-stops-gracefully (key off `state.attempts` NOT `state` — controller starts 'stopped' and `forward()` transiently re-enters 'stopped', so `waitFor(state==='stopped')` false-matches).
-
-**On-device verification reality (Xiaomi 13 fuxi, Android 16, WebView 147, Google TTS):** CANNOT reproduce the fault — offline auto-advance works, even offline+screen-off (foreground-audio service keeps the WebView UNthrottled; Google local engine emits onDone offline). Matches maintainer's non-repro. Needs the reporter's engine (Samsung/Supertonic/Chinese-network voice). Force the engine-error path on this device by setting a `*-network` voice offline. See [[cdp-android-webview-profiling]] for the CDP recipe; gotcha: `window.__TAURI_INTERNALS__.invoke`/`runCallback` get RE-INJECTED on Next.js client nav (wrappers revert) — `console.log` wrapping persists, so trace via the `[TTS] speak` / `[TTS] Initialized TTS for section N` logs instead.

-Microsoft OneDrive as a 4th cloud sync backend (after WebDAV/[[gdrive-provider-multipr-status]]/[[s3-r2-sync-provider]]), full parity, issue readest/readest#5007. Brainstormed→spec→plan→executed via subagent-driven-development (each task fresh implementer + reviewer, final opus whole-branch review). Design `.agents/plans/2026-07-09-onedrive-provider-design.md`, plan `...-plan.md`.
-
-**Worktree `/Users/chrox/dev/readest-feat-onedrive-sync`, branch `feat/onedrive-sync`, 28 commits on origin/main `870a62e0e`, HEAD `5f97dd706`. LOCAL ONLY (not pushed — confirm-before-push). Full suite 7177 pass, lint clean, rust fmt:check clean (0 .rs changed). MERGE-READY pending the Azure client id (ops).**
-
-**Architecture (6 phases):**
- **Phase 0 — shared OAuth extraction (highest risk, behavior-preserving):** moved gdrive's generic OAuth out of `providers/gdrive/auth/` into `src/services/sync/providers/oauth/` — `pkce`(buildAuthUrl now takes authEndpoint+extraParams), `parseRedirect`, `tokenEndpoint`(exchangeCode/refreshAccessToken take tokenEndpoint param), `oauthFlow`(OAuthClientConfig gained authEndpoint/tokenEndpoint/redirectUri/redirectScheme/authParams), `oauthDesktop/Android/Ios` runners (read redirect+endpoints from config; desktop uses inline `schemeMatches`), `keychainTokenStore`(KeychainTokenPersistence keyed by `(key,label)`), `persistedOAuth`(PersistedOAuth: single-flight refresh + injected tokenEndpoint/resolveAccountLabel/providerLabel). gdrive refactored onto it: `googleOAuthConfig.ts` (buildGoogleOAuthConfig, reverse-DNS redirect stays gdrive), `googleDriveAuth.ts` (resolveGoogleAccountLabel + createGoogleDriveAuth); `PersistedDriveAuth.ts` DELETED. Google sign-in byte-identical (test-guarded).
- **Phase 1 — transport:** Graph App Folder is PATH-addressed (unlike Drive's id cache) → `OneDriveProvider` resembles WebDAV, much simpler. `graphRest.ts` builds `/me/drive/special/approot:/{path}...` (colon form; root = `/approot/children` no-colon; per-segment encodeURIComponent). `head` maps `cTag`→etag. `ensureDir` creates folders, 409 nameAlreadyExists = success. mapGraphError/withBackoff mirror Drive.
- **Phase 2 — desktop:** `microsoftOAuthConfig`(authority `/common`, scope `Files.ReadWrite.AppFolder offline_access User.Read`, redirect `readest-onedrive://auth`), `onedriveAuth.createOneDriveAuth` over shared PersistedOAuth (MS ROTATES refresh tokens → `refreshed.refreshToken ?? refreshToken` uses the new one), keychain key `onedrive_token_set`, connect/build/wiring, exclusive selection (cloudSyncProvider/Activation), `OneDriveForm`+IntegrationsPanel row (RiMicrosoftLine), CSP+deep-link.
- **Phase 3 — mobile:** OS-dispatched runner (Android Custom Tab / iOS ASWeb), ingress filter drops `readest-onedrive://` (`isOneDriveOAuthRedirectUrl` in useAppUrlIngress), Info-ios.plist + AndroidManifest scheme (host `auth`).
- **Phase 4 — web:** full-page auth-CODE+PKCE (`webAuthCodeFlow.ts`; MS SPA token endpoint is CORS-enabled → gets a rotating refresh token, BETTER than gdrive's implicit web flow). Web reuses the shared PersistedOAuth via a sessionStorage `webOneDriveTokenPersistence` (NO separate web auth class). Route `app/onedrive-callback/page.tsx` (reads code+state from query, validates CSRF before exchange).
- **Phase 5 — streaming:** `uploadStream` = Graph `createUploadSession` → single PUT to pre-authed uploadUrl via `tauriUpload` with `Content-Range: bytes 0-(N-1)/N` (size via `@tauri-apps/plugin-fs` `stat()` — tauriUpload can't compute it); `downloadStream` = content 302 → `tauriDownload`+bearer. Tauri-only; web buffered.
- **Phase 6 — i18n:** 6 keys x 33 locales, ADDITIONS-ONLY (scanner has `removeUnusedKeys:true` → prunes ~1350 live keys, NEVER run it; adapt the gdrive analog per locale, en omitted via key-as-content fallback).
-
-**KEY LESSONS (reusable for the NEXT cloud provider):**
- **`src/utils/settingsSync.ts` is a #4580 multi-window touchpoint the plan MISSED** — `CloudSyncProviderFlags`/`mergeSyncedGlobalSettings`/`broadcastGlobalSettings` payload must gain an optional `<provider>?: {enabled, providerSelectedAt}` slice or activating the provider broadcasts it as absent and a stale window clobbers the activation off (silent provider revert). Per-task reviews all passed; only the final whole-branch (opus) review caught it. Fixed in `5f97dd70`. See [[multiwindow-settings-clobber-4580]].
- **Every provider-kind touchpoint that has an `s3` branch needs an `onedrive` sibling** — cloudSyncProvider (display/key/getCloudSyncProvider/applySyncBooksAutoEnable), cloudSyncActivation (isThirdParty/withActiveCloudProvider), providerRegistry, constants, types, both file-sync hooks, IntegrationsPanel, backupService blacklist, settingsSync. fleetDetection/fileSyncStore/syncCategories are generic (free).
- **i18n analog-adaptation trap:** ru/sl/uk gdrive analog contained the literal "Google Drive" (not just "Drive"), so an automated `Drive→OneDrive` swap produced "Google OneDrive" (brand mashup). Grep the whole locale set for cross-brand mashups after an analog-swap pass.
- **PRE-EXISTING FOLLOW-UP (not OneDrive):** `s3.{deviceId,lastSyncedAt,providerSelectedAt}` are NOT in `BACKUP_SETTINGS_BLACKLIST` (s3 device-local fields leak into cross-device backup). Warrants a separate one-line PR + a test asserting all 4 third-party providers blacklist those 3 fields uniformly.
-
-**OPS DEPENDENCY (blocks live sign-in only; code+tests green without it):** create an Azure app registration — public client; redirect URIs `readest-onedrive://auth` (Mobile-and-desktop) + `https://web.readest.com/onedrive-callback` + `http://localhost:3000/onedrive-callback` (SPA); scopes `Files.ReadWrite.AppFolder offline_access User.Read`. Bake the client id as `OFFICIAL_MICROSOFT_CLIENT_ID` in `buildOneDriveProvider.ts` (currently `''` → `getMicrosoftClientId()` returns undefined → OneDrive row hidden, provider unavailable) or set `NEXT_PUBLIC_MICROSOFT_CLIENT_ID`. Allow `graph.microsoft.com` + `login.microsoftonline.com` in the web edge CSP.

-Issue #4272: OPDS auto-download on copyparty missed books in subdirectories (and skipped folders containing only subfolders). Copyparty (`?opds` on any directory) emits subfolders as `rel="subsection"` nav entries (`type="application/atom+xml;profile=opds-catalog"`), files as acquisition entries with `?dl` hrefs, no pagination, no "by newest" feed (template: `copyparty/web/opds.xml`).
-
-**Fix (PR #4948, MERGED 2026-07-06):** in `src/services/opds/feedChecker.ts`, `checkFeedForNewItems` now branches: catalogs WITH a "by newest" feed keep the old behavior (newest feed + rel=next only, never crawl — whole-library subscription hazard); catalogs WITHOUT one are directory-style and get a breadth-first `crawlFeeds` over `getSubsectionURLs` (skips facet/self/up/start/top/search rels and non-catalog types), bounded by `MAX_CRAWL_DEPTH=5`, `MAX_FEEDS_PER_CRAWL=50` (incl. root fetch), and the `visited` set. rel=next pagination still capped at `MAX_PAGES_PER_FEED` per chain. Collected entryIds are added to the local knownIds copy so a book listed by two crawled feeds is collected once (NOT persisted — failed downloads must stay retryable). Tests: `src/__tests__/services/opds-feed-crawl.test.ts` (mocked `fetchWithAuth` serving URL→XML fixtures).
-
-**Unresolved iOS half of #4272:** reporter saw "33 downloads failed" on iPhone while macOS downloaded all base-dir books fine. Same TS/Rust download path both platforms (`download_file` in `src-tauri/src/transfer_file.rs`); most plausible cause is iOS suspending the app mid-sync and killing in-flight reqwest connections (35 epubs at DOWNLOAD_CONCURRENCY=3 takes minutes). Retry/backoff (MAX_RETRY_ATTEMPTS=3) picks them up on later launches, but after 3 failures entries are moved to knownEntryIds and permanently skipped with no recovery UI — a repeatedly-interrupted catalog silently loses books. Possible future work: iOS beginBackgroundTask around the sync, or don't hard-cap retries for network-type errors.

-Issue #4988: OPDS auto-download failed while manual browse/download of the same catalog worked (reporter: iPad + Calibre-Web NextGen behind nginx https). Reporter blamed the credential-less HEAD probes — red herring: those are `probeAuth` challenge probes, their 401 is by design and the Basic header still reaches the GET.
-
-**Real signature:** feed GETs and HEAD probes appear in the server log, download GETs never do → the native `download_file` dies client-side in the TLS handshake. The Tauri http-plugin path (`opdsReq.ts`) always passes `danger: {acceptInvalidCerts: true}`, but `transfer_file.rs` builds its reqwest client with **rustls**, which ignores the OS trust store — self-signed, private-CA, or incomplete-chain certs all fail unless `skip_ssl_verification` is set. Manual download (`page.tsx handleDownload`) got `skipSslVerification: true` in #2900 (for #2871); `autoDownload.ts downloadAndImport` never did.
-
-**Fix (2026-07-08, PR #5002):** pass `skipSslVerification: true` in autoDownload's `downloadFile` call. Test in `opds-auto-download.test.ts`.
-
-**How to apply:** any new code path that downloads via native `download_file`/`tauriDownload` from a user-configured server must mirror the manual path's `skipSslVerification` — TLS behavior differs between the http plugin (danger flags on) and transfer_file (strict rustls by default), so "browse works but download fails, nothing in server logs" = check this first. "curl works without -k" on another machine proves nothing about rustls trust.

-#4750 (PR #4755, merged): when an OPDS `feed.groups.length >= 2`, `FeedView` renders each group's publications/navigation as a horizontal carousel (`src/app/opds/components/GroupCarousel.tsx`) instead of the grid; single-group feeds keep the grid. Matches Thorium.
-
-`GroupCarousel` wraps a horizontal `react-virtuoso` `Virtuoso` (`horizontalDirection`), so only in-view items mount → covers load lazily as you scroll (verified via network: ~12 covers/group fetched regardless of group size; far-right items fetch only after scrolling to them).
-
-Gotchas (cost real debugging):
- `VirtuosoHandle.scrollBy({left})` is a **no-op** in horizontal mode (the handle maps to the vertical axis). Page the arrows by **index** via `scrollToIndex({index, align, behavior})`, tracking the visible range from `rangeChanged`.
- Virtuoso sizes the horizontal track **lazily**, so a pixel `scrollBy` on the scroller element clamps to the currently-rendered width — another reason to scroll by index.
- Arrow visibility comes from `atTopStateChange`/`atBottomStateChange` (top=left, bottom=right). Row height is measured from the first `[data-carousel-item]`; arrows are vertically centered on the cover by measuring the first `<figure>` (cards have title/author below, so centering on the whole row looks low).
- Scrollbar hidden via a scoped `.no-scrollbar` util in `globals.css`; arrows use `eink-bordered`.
- Tests must mock `react-virtuoso` (jsdom has no layout) like the TOCView/BooknoteView tests — render all items via `itemContent`.
-
-`PublicationCard` (shared by carousel + grids) got rounded covers (`overflow-hidden rounded`, matching the library bookshelf) and dropped the inline acquisition/price badge — that badge still renders on the detail page (`PublicationView`).

-Issue #4782: adding a generic "Popular Catalog" (e.g. Project Gutenberg) to My

-duplicate.
-
-Root cause in `src/app/opds/components/CatalogManager.tsx`: on add, only the

-with its Browse button, so the entry visibly appeared in both sections.

-`src/app/opds/utils/opdsUtils.ts` dedups by **normalized URL** (trim +
-lowercase), mirroring the store's `findByUrl`. Component computes
-`popularCatalogs = isOnlineCatalogsAccessible ? getUnaddedPopularCatalogs(POPULAR_CATALOGS, catalogs) : []`;
-the section already auto-hides on `popularCatalogs.length === 0`, so once all

PR #4206 (commit 83607d14e) made `fetchWithAuth` (`src/app/opds/utils/opdsReq.ts`) send Basic preemptively (for Calibre-Web-style servers that return anonymous 200 without a challenge), which dead-ended all digest-mode Calibre servers: the retry logic only fired on 401/403, so users saw "Failed to load OPDS feed: 400 Bad Request" (reported on Android, but platform-independent — web proxy relays the 400 too).
-
-**Fix (2026-07-08, PR #5002):** in `fetchWithAuth`, when the first response is 400 AND preemptive Basic was sent, re-issue the request once *without* credentials to surface `WWW-Authenticate`, then let the existing 401/403 negotiation pick Digest. Direct path strips the Authorization header; proxy path strips the `auth=` query param. Tests in `src/__tests__/utils/opds-req.test.ts`.
-
-**Why:** the two auth-server archetypes conflict — anonymous-200 servers need preemptive creds (#4206), strict digest servers reject them with 400. Only runtime negotiation satisfies both; don't "fix" one archetype by regressing the other.
-
-**How to apply:** any preemptive-auth optimization needs a recovery path for servers that reject the scheme outright (400/4xx without challenge), not just for 401/403 challenges. The app's Digest implementation itself is correct (Calibre's strict parser answers 401, not 400, to its headers). Verify against a real Calibre: dummy creds distinguish malformed (400) from wrong-password (401). Beware: Calibre throttles repeated failed logins with transient 503s.

-Readest issue #4749 (pglaf/Gutenberg test feed `https://opds-test.pglaf.org/opds/`). Two related OPDS bugs, both fixed together.
-
-**1. Summary publications need a `self`-link dereference.** OPDS 2.0 feeds may list a publication with only minimal metadata + a `rel:"self"` link of type `application/opds-publication+json` (no acquisition links, no description) — the server sends the full record only when the client follows that link on click. Thorium does this; Readest did not.
- New `src/app/opds/utils/opdsPublication.ts`: `getPublicationDetailHref(pub)` finds the `rel:"self"` link whose type is `application/opds-publication+json` or Atom `application/atom+xml;type=entry`; `parsePublicationDocument(text, docURL)` parses JSON or Atom-entry XML (reuses foliate `getPublication`) and **absolutizes** links/images hrefs against `docURL` so downloads/cover resolve regardless of the feed's `baseURL`.
- `page.tsx`: renamed derived `publication` → `basePublication`; an effect fetches the detail doc (via `fetchWithAuth` + proxy refs) when `selectedPublication` is set AND a detail link exists (skip directly-loaded entry docs — already full); merges as `{ metadata: resolved.metadata, links/images: resolved.* || base.* }` keyed by `source===basePublication` so a stale fetch can't bleed into the next selection. Summary renders immediately, upgrades in place.
-
-**2. JSON `description` is HTML.** OPDS 2.0 keeps the summary in plain `metadata.description` (no typed `<content>`), and pglaf fills it with `<p>...</p>`. `PublicationView` rendered `<p>{description}</p>` → literal tags. Fix: `getOPDSDescriptionHtml(content ?? description)` so the (sanitized) markup renders. See [[bug-patterns]] and prior [[OPDS HTML description (#4503)]] decode-once+sanitize.
-
-**Why:** less data per feed page + faster load; client dereferences on demand.
-**How to apply:** when an OPDS publication looks under-populated, check for a `rel:"self"` publication-type link before assuming the feed is the whole record. Related OPDS notes: opds-firefox-strict-xml-4479, opds2-json-search-4502, opds-html-description-4503.

-Issue #555 (Apple Books/Kindle turn animations): implemented `pageTurnStyle` view setting (Push/Slide/Curl). **MERGED 2026-07-05**: app PR readest#4940 → main `75f1fafe9` (11 commits, includes the Xcode-26.2 swift-rs build fix) + foliate fork readest/foliate-js#48. Mesh curl verified live on macOS/iOS/Android; Windows/Linux capture backends still open (CSS-curl fallback). Worktree removed post-merge (`pnpm worktree:rm feat/page-turn-styles-555` — takes BRANCH name not path; plain `git worktree remove` refuses trees with submodules); phase-2 plan preserved at main checkout `apps/readest-app/.claude/plans/page-curl-mesh-tauri-555.md`.
-
-**Phase 2 (true mesh curl on Tauri, 2026-07-04):** plan at worktree `apps/readest-app/.claude/plans/page-curl-mesh-tauri-555.md` (plans dir is gitignored). Done + committed: WebGL curl renderer `src/utils/pageCurl.ts` (000814a51) and native-bridge `capture_webview_region` for macOS/iOS (85e592fd1). Renderer gotchas: WebGL canvas needs `preserveDrawingBuffer:true` or readPixels silently returns zeros after any await (browser composited); the clip-space Y flip mirrors triangle winding so `frontFace(CW)` or gl_FrontFacing (front vs whitened back) inverts; corner-grab fold tilt must decay `(1-p)`; travel = `w + PI*r_end`; **WebKit ignores `UNPACK_FLIP_Y_WEBGL` for ImageBitmap uploads** — curl was upside down on iOS (back read as 180°-rotated instead of Apple-Books horizontal mirror); fix = upload unflipped + `vUv = aPos` (f9a49fd4c); test textures MUST be vertically asymmetric to catch flips, and running the vitest browser suite on Playwright WebKit (`instances: [{ browser: 'webkit' }]` temporarily in vitest.browser.config.mts) reproduces iOS WebGL behavior. Capture: binary `ipc::Response` PNG; macOS legacy objc msg_send WKWebView takeSnapshot in plugin `src/platform/macos.rs`, iOS Swift + base64 across JSON plugin boundary. Orchestration committed: `CapturedPageTurn` (`src/app/reader/utils/capturedTurn.ts`, renamed from MeshCurlTurn/meshCurl.ts in 5ba62ef07, host-callback DI, browser-tested) runs capture→overlay→instant-nav→animate with a per-turn style ('curl' WebGL mesh | 'slide' flat canvas); turns the FULL gridcell (header/footer/margins ride the sheet, per Apple Books video + user request 7e300a7bd) — NOTE this diverges from the VT slide/curl which clips furniture static; instant nav = drop `animated` attr (ALL paginator animated paths incl. VT gate on it); backward = mirrored old-page-recedes (rendererRtl = forward?rtl:!rtl); `useCapturedTurn` (renamed from useMeshPageCurl) wraps view.prev/next + touch interceptor (priority 5, ruler=10 swipe-flip=0), drag progress from deltaX/gridWidth, cancel un-curls then navs BACK under the flat overlay; `applyPageTurnAttributes` = single source for turn-style/no-swipe (FoliateViewer open + ControlPanel pageTurnStyle/animated/disableSwipe effects); session `captureBroken` flag → paginator turn-style where VT is fully supported, push elsewhere. Android capture done (PixelCopy in NativeBridgePlugin.kt: CSS px × density + getLocationInWindow; kotlin compile check = `gen/android ./gradlew :tauri-plugin-native-bridge:compileFossDebugKotlin`). **Android perf gotcha (user-verified fixed)**: full-density PNG encode = ~1.5s/turn on Xiaomi 13 (3x, 1080×2400) → curl read as broken; fix = JPEG q85 + dest bitmap capped at 2× CSS px (PixelCopy scales into smaller dest for free) → invoke 1550ms→34ms, overlay mounts 132ms after tap; JS must NOT hardcode blob type 'image/png' (decoder sniffs). iOS same optimization (3e7f58135): `jpegData(0.85)` off-main + `WKSnapshotConfiguration.snapshotWidth = width*2/scale` when scale>2 (snapshotWidth is in POINTS; image px = points×scale); macOS stays PNG. CDP verify lane: `pnpm dev-android` + helpers in `src/__tests__/android/helpers/` (forwardWebViewDevtools + CdpPage.evaluate; `window.__TAURI_INTERNALS__.invoke('plugin:native-bridge|capture_webview_region',{payload})` times raw capture; `document.querySelector('foliate-view').next()` triggers the wrapped turn; `Page.captureScreenshot` for mid-turn frames). Remaining: Windows/Linux capture; LIVE curl visuals still unverified (macOS smoke test reached reader, push path fine; interrupted — user was at the machine). Live-run gotchas: dev binary exits instantly if production Readest runs (single-instance, same bundle id — quit prod first); computer-use MCP can't see/screenshot the bare target/debug binary — drive with bash `screencapture` + JXA CGEvent clicks (AppleScript AX `click at` fires the Book-Details action, not reader open). Shared `target/` symlink gotcha: deleted worktrees leave stale plugin build-script caches ("failed to read plugin permissions" from dead paths) — `cargo clean -p <plugin>...`.
-
-**Curl final (curved corner fold):** radial-gradient mask on the OLD pseudo — transparent disc grows from the outer-bottom corner (forward) / spine-side corner (backward), fold edge = curved arc like a lifted page corner. The fold animates a GRADIENT STOP via registered `@property --foliate-fold` (re-rasterizes mask per frame). **VT pseudo paint quirks (computed style LIES — always verify with screenshots via vitest browser `page.screenshot`):** width animations compute but don't repaint; `mask-position`/`mask-size` animations paint at wrong scale/not at all; masks apply ONLY to the static old snapshot, NOT the live new layer (backward turns must choreograph old receding, not new unfolding); UA sets `mix-blend-mode: plus-lighter` on old/new (force `normal`); back both layers with `--foliate-vt-bg` (from doc `--theme-bg-color`, textured themes have transparent page bg per #4399); paint uses LINEAR progress ignoring easing (cosmetic). `filter`/`clip-path` order: filter runs BEFORE clip/mask → drop-shadows get cut with the page. **VT skips (`ready` rejects InvalidStateError) when `document.hidden`** — Chrome-MCP automation tab is usually hidden; verify in vitest browser (visible) with frozen animations + screenshots. **Header/footer in both layers:** app marks the boundary with `data-view-transition-root` on the gridcell; paginator prefers `closest('[data-view-transition-root]')` from the outermost shadow host. **True mesh bend on web: impossible** (no DOM pixel access); plan = WebGL curl shader + Tauri native webview capture (WKWebView takeSnapshot / PixelCopy / CapturePreview) as a follow-up; web keeps the arc fold.
-
-**iOS 18 VT crash + gating (2026-07-06, 5ba62ef07):** iOS 18.7 WKWebView HAS `document.startViewTransition` but the VT slide CRASHES the WebContent process (Sandbox `process-info-codesignature` deny then WebContent gone; Android WebView 147 fine) — API presence is NOT a safe gate. App-side gate `supportsViewTransitionTurns()` (in `useCapturedTurn.ts`) = startViewTransition + `CSS.supports('view-transition-group', 'nearest')` (nested VT groups: Chrome/Edge/WebView 140+ ONLY; Safari ≤27 and Firefox lack it per caniuse — so ALL WebKit and Gecko engines get no VT turns). `applyPageTurnAttributes` only sets `turn-style` when the gate passes, so synced slide/curl settings degrade safely. Fallback on Tauri: `getCapturedTurnStyle()` routes slide → the capture pipeline with `PageSlideRenderer` (`src/utils/pageSlide.ts`, 2D canvas, translateX toward spine = `(rtl?1:-1)*progress*width` with the shared rendererRtl mirror; overlay gets `overflow:hidden` clip + box-shadow edge like the VT slide; backward = old-slides-out-mirrored since only the OUTGOING page can be captured — the overlay div sits above the live iframe so a second capture would include it). Web without full VT: push only; ControlPanel hides Slide/Page Curl (`turnStyleOptions` = push + layered when `supportsViewTransitionTurns() || isTauriAppPlatform()`) and coerces an unsupported synced value to display as Push. Tests: `useCapturedTurn.test.ts` (jsdom, stub CSS.supports + startViewTransition; `vi.stubEnv('NEXT_PUBLIC_APP_PLATFORM','tauri')` toggles isTauriAppPlatform) + slide cases in `captured-turn.browser.test.ts` (read canvas transform via `new DOMMatrixReadOnly(getComputedStyle(c).transform).e`).
-
-**Mechanism:** slide/curl need old+new page as separate layers — impossible in the rigid multicol strip (see [[vertical-rl-horizontal-pagination-624]]). The View Transitions API rasterizes the outgoing page (annotations included) and animates the snapshot over the live, stationary incoming page. Axis-agnostic: works for vertical-rl too. `turn-style` attribute on the renderer; falls back to push/two-phase when `document.startViewTransition` is missing (old WebKitGTK/iOS<18).
-
-**Hard-won gotchas:**
- **Shadow-DOM tree scoping:** `view-transition-name` on elements inside shadow roots creates NO capture group (Chrome 149) — the name must go on the outermost shadow host in the DOCUMENT tree (walk `getRootNode() instanceof ShadowRoot → .host`). In Readest that's the `foliate-view` element.
- **Header/footer stay static** (user requirement): app header/footer (SectionInfo/ProgressBar) are siblings positioned over the margins; the host snapshot covers margins too and slides over them. Fix: clip `::view-transition-group(foliate-turn)` with `--foliate-vt-clip: inset(margins)` (margins read from `--_margin-*` on #top) so margins stay owned by the static root snapshot.
- **Landing race:** a neighbor view load mid-transition re-anchors to the stale pre-turn anchor; re-assert `containerPosition = offset` after `transition.finished` (push's cssAnimateScroll does the same at its end).
- **Finger tracking = scrubbed VT:** start the transition at drag threshold (direction from net dx), `await ready`, `updateTiming({easing:'linear'})` + `pause()` all `(foliate-turn)` pseudo animations, drive `currentTime = progress × duration` from the finger. Release: `play()` to commit; cancel = `reverse()`, restore `containerPosition` in the anims-finished microtask (before next paint — avoids flashing the target page), then `skipTransition()`.
- **getComputedStyle on VT pseudos lies:** it reports rule-matched styles even with no active transition — test with `document.getAnimations()` filtered by `effect.pseudoElement` instead; a layer styled `animation: none` has no entry (proves it's stationary).
- Choreography via classes on documentElement (`foliate-vt-{slide,curl} -{forward,backward} -{left,right}`) + one injected document-head stylesheet (pseudo tree lives on :root, not the shadow root). Old-on-top needs `z-index: 1` (new is on top by default). Curl = perspective rotateY fold (flat snapshot can't mesh-bend); side class = spine side = rtl?right:left.
-
-Tests: `paginator-turn-styles.browser.test.ts` (slide layering old-moves/new-still, curl, vertical-rl, drag tracking commit + revert, push fallback via deleting startViewTransition).

-Issue #4785: swipe page-turn animation drops frames, worst crossing .xhtml
-section boundaries, "first open" (Android/Xiaomi). Repro book is a Taiwan light
-novel with custom fonts + `.bg`/`background-attachment:fixed` front-matter.
-
-Root cause (in `packages/foliate-js/paginator.js`, a submodule):
-`#replaceBackground()` rebuilt its whole paint context **every frame** of both
-swipe phases — `getComputedStyle(<html>)` + `this.size` + one
-`getBoundingClientRect()` **per rendered view** + a per-view background-reset
-write loop + full `#background` DOM rebuild. Those forced reads scale with the
-number of loaded views, which **peaks at a chapter boundary** because adjacent
-sections are preloaded there — hence "worst at boundaries". Two callers ran it
-per-frame: the snap `syncBackground` rAF loop (`#scrollTo`) and the drag-phase
-container `scroll` listener (`#onTouchMove`→`scrollBy`→scroll event).
-
-Everything `#replaceBackground` reads is **invariant for one gesture** (theme/
-texture, bg+container geometry, each view size+bg) — only scroll offset changes.
-
-Fix:
- Split into `#readBackgroundStyle` / `#computePaginatedBgContext` (the reads) +
-  `#paintPaginatedBackground(ctx, atPosition)` (writes only; calls the unchanged
-  pure `computeBackgroundSegments`).
- `#bgAnimContext` field snapshots context once: set in `#onTouchStart` (drag)
-  and at the start of the animated branch in `#scrollTo` (snap); cleared in
-  `#onTouchEnd` and both animation `.then()`s. `#replaceBackground` uses
-  `this.#bgAnimContext ?? this.#computePaginatedBgContext()`.
- Also deferred the heavy mid-drag forward preload: added `&& !this.#touchScrolled`
-  to the scroll-listener `#loadAdjacentSection` gate (columnize/expand on the main
-  thread janked the drag). The scroll that settles the gesture re-fires the gate
-  with the finger up, so the buffer still tops up.
-
-Tests: `src/__tests__/document/paginator-background-anim-perf.browser.test.ts`
-(real Chromium) drives `next()` (snap) and a synthetic touch drag, spying on the
-primary iframe `<html>` getComputedStyle. Pre-fix: 39 reads (snap) / 7 (drag);
-post-fix ≤3 / ≤1. Existing `paginator-background-segments.test.ts` (pure
-`computeBackgroundSegments`) stays green — visual output unchanged.
-
-Scrolled-mode branch kept inline in `#replaceBackground` (never the per-frame hot
-path). Behavior preserved: scrolled set every view bg so the old reset loop was
-redundant; `containerSize = containerRect[sideProp]` == old `this.size`.
-
-NOT the cause (ruled out): `computeBookNav`/`nav.json` is awaited before the view
-renders, so first/second-open in-memory state is identical — it can't explain
-reading-time swipe jank. See [[booknote-view-autoscroll-4352]] neighbors in
-Paginator & Scroll. Related: [[paginator-swipe-bg-flash]],

-PR #4725 fixed three Shift+P paragraph-mode bugs (#4717). Follow-on to #4723 (Alt+P proofread + initial overlay attempt). Three reusable, non-obvious findings:
-
-**1. `eventDispatcher.dispatch` live-Set re-entrancy (the widest-reach gotcha).** `dispatch()` iterated the live `asyncListeners` Set while `await`ing each listener. A listener that triggers a React state change which re-runs an effect that re-subscribes a handler for the SAME event gets that new handler invoked in the same dispatch loop → the event double-fires. Symptom here: one Shift+P toggled paragraph mode twice (exit→re-enter "flash"); `useParagraphMode`'s `toggle-paragraph-mode` subscription effect has `paragraphConfig.enabled` in deps, so the exit's awaited `dispatch('paragraph-mode-disabled')` re-subscribed mid-loop. Fix = snapshot before iterating: `for (const l of [...listeners])` in `dispatch` (`dispatchSync` already did). **Applies to ANY event whose handler re-subscribes.**
-
-**2. Overlay key handling = dialog/alert pattern, NOT a global window listener.** The maintainer (chrox) explicitly rejected wiring `onEscape` into useShortcuts. Correct pattern: the overlay's container is `role=dialog tabIndex=-1`, gets `containerRef.current.focus({preventScroll:true})` on open, and handles Escape / toggle shortcut / nav in its OWN `onKeyDown` (stopPropagation so the global handler can't double-fire). Add `outline-none` to the programmatically-focused non-tab-stop container or it draws a focus ring around the whole viewport. The old capture-phase `window.addEventListener('keydown',...,true)` + `stopImmediatePropagation()` swallowed global shortcuts and only fired when focus was on the parent doc (not the foliate iframe).
-
-**3. Paragraph-mode resume rewound to chapter start.** Two causes: (a) entering/exiting scrolled the underlying view to the focused paragraph's START via `renderer.goTo`/`scrollToAnchor`; when the page-top paragraph began on the previous page this rewinds a page, and repeated enter/exit accumulates. Fix = `focusCurrentParagraph(align=false)` on resume/first-mount, drop the exit `scrollToAnchor`; navigation keeps `align=true`. (b) resume preferred the rAF-debounced `readerStore` progress and a stored last-paragraph CFI (`view.getCFI(docIndex, paragraphBlockRange)`) that comes out MALFORMED (e.g. `epubcfi(/6/18!,/4/110,/4)`) and `resolveCFI`s to a non-null EMPTY range, shadowing the correct candidate in the `??` chain and sending `findByRangeAsync` to `first()` (the title). Fix = resume from `view.lastLocation.cfi` FIRST.
-
-**foliate `view.lastLocation` vs readerStore progress:** `view.lastLocation = {cfi, range, ...}` is set SYNCHRONOUSLY by foliate on every relocate; the readerStore progress is rAF-debounced (FoliateViewer `commitRelocate`) and lags/desyncs. For any resume/current-position logic prefer `view.lastLocation.cfi` (CFI is document-instance-independent, survives the section iframe being recreated on toggle — a stored `Range` does not). `view.lastLocation` is NOT in the FoliateView TS type by default (had to add it).
-
-**Verification/harness gotchas (claude-in-chrome on the reader):** synthetic keystrokes (`computer key shift+p`) BUFFER/DROP chaotically — single presses vanish then fire in delayed bursts, creating inconsistent multi-toggle states; `ArrowRight` repeat worked, single Shift+P often didn't. Menu clicks (View menu → Paragraph Mode) are reliable for toggling. The content iframe lives in the foliate-view shadow DOM (`iframeCount:0` at top level); focus on `FOLIATE-VIEW` → keydown arrives as an `iframe-keydown` postMessage, focus on parent → real window keydown. Probe live state via `document.querySelector('foliate-view').lastLocation`. Tool returns containing "overlay=" strings sometimes hit a `[BLOCKED: Cookie/query string data]` filter — return JSON objects instead.

-Added a **Contrast** stepper to the reader **View menu** (`ViewMenu.tsx`) for fixed-layout / image docs (PDF/CBZ/FXL-EPUB). Models the existing `invertImgColorInDark` / `zoomLevel` pattern. Increase/decrease/reset (+ / – / ◐%), gated inside the `rendition?.layout === 'pre-paginated'` block, placed right under the Zoom Level control.
-
-**Key wiring (mirror this for any future fixed-layout image adjustment — brightness, saturation):**
- Type: `contrast: number` in `BookStyle` (`types/book.ts`, fixed-layout section). Default `contrast: 100` in `DEFAULT_BOOK_STYLE` (`constants.ts`); also `MIN_CONTRAST=50`/`MAX_CONTRAST=300`/`CONTRAST_STEP=10`.
- Filter applied in `applyFixedlayoutStyles()` (`utils/style.ts`) on the `img, canvas` rule. **GOTCHA:** CSS `filter` is a single property — a second `filter:` line overrides the first. Build ONE declaration: collect `invert(100%)` (dark+invert) and `contrast(${c}%)` (c!==100) into an array, join with spaces. invert/contrast commute so order is irrelevant. Contrast applies in light mode too (independent of dark/invert).
- **Local to current document:** `saveViewSettings(envConfig, bookKey, 'contrast', value, /*skipGlobal*/ true, /*applyStyles*/ true)`. `skipGlobal=true` forces the per-book branch (`applyViewSettings(bookKey)`) regardless of `isGlobal`, so it never touches `globalViewSettings`.
- **Re-apply on change:** add `viewSettings?.contrast` to the dependency array of the `FoliateViewer.tsx` effect (~L829) that calls `applyFixedlayoutStyles` on every rendered doc. New pages pick it up via the on-load `applyFixedlayoutStyles(detail.doc, viewSettings)` call (~L321). Re-render is driven by `setViewSettings` updating `bookDataStore` config → parent `BooksGrid` re-renders FoliateViewer.
-
-Test: `src/__tests__/utils/fixed-layout-styles.test.ts` (new) asserts the combined `filter: invert(100%) contrast(150%)` and the no-filter-at-100% cases. The settings dialog `ThemePanel.tsx` was intentionally NOT touched — request was View menu only. Related: [[tap-to-open-image-table-4600]], css/style hub `src/utils/style.ts`.

-PDF **scrolled mode** showed blank pages while scrolling on Android (#4795, resurfacing #4031). Reproduced + fixed + CDP-verified on Xiaomi 13 (fuxi).
-
-**Root cause (measured via CDP on-device):** per-page render (`pdf.js` `onZoom`→`render()`: canvas raster + text layer + annotation layer) ≈ **415 ms** uncached / ~65 ms cached, but the scrolled-mode IntersectionObserver used `rootMargin: '50% 0px'` (~0.5 page of lead). Loads also had **unbounded concurrency** (observer fired `#loadScrollPage` for every intersecting page) and **no viewport prioritization**, so the slow render never finished before the page scrolled into view, and a fling spawned dozens of competing renders. Per-page canvas ≈ **7 MB** at dpr 3 (screen-res, NOT the ~50 MB I first feared) → memory headroom existed; the #3470 OOM was byte-range *parsing* flood (`MAX_CONCURRENT_RANGES`, orthogonal).
-
-**Fix** (`packages/foliate-js/`):
- `fixed-layout.js`: widened observer to `rootMargin: '200% 0px'` (~2 viewports lead); observer now only **flags `page.visible`** and calls new `#scheduleScrollPages()`.
- New pure exported `planScrollModePages({pages, currentIndex, maxLoaded, maxConcurrent, loadingCount})` → `{load, evict}`: loads **visible+idle pages nearest currentIndex first, bounded by `maxConcurrent - loadingCount`**; evicts **farthest non-visible loaded** beyond `maxLoaded`; **never evicts a visible page** (distance = `|index - currentIndex|`). Unit-tested in `src/__tests__/document/fixed-layout-scroll-scheduler.test.ts`.
- `#scrollMaxLoaded 8→12` (live-canvas cap = memory ceiling), `#scrollMaxConcurrent=3`, `#scrollLoadingCount` tracked in `#loadScrollPage` (inc on start, dec in `finally`, then reschedule so a freed slot pulls the next nearest page). Removed `#evictScrollPages` (scheduler handles it).
- **Terminal `error` state**: a load that throws or returns no src sets `state='error'` (not `'idle'`) so the post-completion reschedule can't retry a persistently failing page in a tight async loop (regression I introduced with reschedule-on-completion).
- `pdf.js`: `MAX_CACHED_PAGES 8→16` (page objects + render blobs are cheap, not the canvas) so back-scroll within the wider window doesn't re-parse.
-
-**Verified (CDP + screenrecord, identical 9-swipe reading-pace test, fresh region):** baseline = mostly blank frames, settled forward lead **+2** (span [-9,+2]); fix = **every frame fully rendered**, forward lead **+4** (span [-7,+4]). Extreme 8-fling (240 pages/2s) still blanks mid-fling (inherent) but settles to rendered content and **no crash**.
-
-**Best-practice cache strategy for scrolled PDF on mobile** (asked during this work): two bounded tiers — live-canvas cap = the hard memory ceiling (sized to window+lead), decoded-page cache a bit larger (cheap); distance/viewport-aware LRU never evicting visible; bound+prioritize loads; release bitmaps eagerly (`canvas.width=0`); the biggest unused lever for low-end devices is **capping effective DPR** (canvas mem ∝ DPR²) — not applied here since 12×7 MB≈84 MB is fine on the Xiaomi.
-
-**CDP on release builds:** the installed Play/release 0.11.12 has **no `webview_devtools_remote_<pid>` socket** — WebView debugging is gated behind the `devtools` Cargo feature (`src-tauri/Cargo.toml`); must build+install `pnpm dev-android` (release + `--features devtools`, same keystore so it updates over the store build, library preserved). CDP `webSocketDebuggerUrl` comes back as `ws://localhost/devtools/...` **with no port** (echoes Host header) → rewrite to `ws://127.0.0.1:9222<path>`; `ws` npm pkg is CJS so import default + destructure. See [[cdp-android-webview-profiling]], [[pdf-oom-range-flood-3470]].
-
-**WIP caveat:** during this work the foliate-js submodule had unrelated uncommitted `paginator.js` WIP (background-anim perf, #4785) — exclude it from any #4795 commit.

-# PDF scrolled-mode wheel double-scroll (#4727)
-
-**Symptom:** In fixed-layout/PDF **scrolled** mode, a mouse-wheel notch scrolls ~2× as far and feels instant when the pointer is **over the page** (the iframe), but a single smooth scroll when over the **page margin**. Reproduces on BOTH web and tauri (reporter saw it only in the WebView2 app, but maintainer reproduced on web too). Paginated mode unaffected.
-
-**Root cause:** `fixed-layout.js` scroll mode (`#loadScrollPage`) attaches a `{ passive: true }` wheel listener to each page iframe's doc that called `this.scrollBy({ top: e.deltaY, behavior: 'instant' })`. The iframe is `scrolling="no"` + `overflow:hidden`, so the browser **already chains** the wheel to the host scroller natively (smooth). The manual `scrollBy` **stacks on top of** that native scroll → 2× distance, the instant jump = the `behavior:'instant'` part, the glide = the native chain. Margin-hover hits the host directly → only the single native scroll → no doubling.
-
-The iframe is interactive (`pointer-events:auto`) only during a 150ms idle window after scrolling settles (`#handleScrollEvent` disables it during active scroll, re-enables 150ms after). A notched wheel slower than ~6/sec puts EVERY notch in that idle window → every notch lands on the iframe → every notch doubles (explains the steady "twice as fast", not just the first tick).
-
-**Fix:** Delete the manual `this.scrollBy(...)`; keep `this.#setScrollIframeInteraction(false)` so the iframe stops intercepting and the rest of the gesture also scrolls the host natively. Native scroll-chaining is the single smooth scroll that matches the margin. The old "forward wheel to host" code wrongly assumed the tick was lost without it.
-
-**Why not preventDefault+manual:** would make page-hover an *instant* scroll, not matching the smooth native margin scroll the user wants. Letting native handle it is the only way to match the margin feel.
-
-**Reproduction / test technique (jsdom can't — needs real layout + real wheel):**
- Standalone Playwright proof: scroll container + `scrolling="no"` srcdoc iframe + the buggy handler, `page.mouse.wheel(0,120)` over the iframe → scrollTop 240 vs 120 over margin; remove `scrollBy` → 120 == 120. (real `mouse.wheel` triggers native chaining; synthetic dispatch does NOT.)
- Committed regression test `src/__tests__/document/fixed-layout-scroll-wheel.browser.test.ts` (browser lane, `pnpm test:browser`): mounts the REAL `<foliate-fxl>` in scrolled mode (minimal fake book: `rendition.viewport`, sections whose `load()` returns `{ src:'srcdoc', data: tallHtml }` — `src` must be truthy or `#createScrollFrame` returns blank; `data` → srcdoc keeps iframe same-origin so contentDocument is reachable), dispatches a **synthetic** `WheelEvent` on the page iframe doc (synthetic wheel doesn't chain natively, so any movement is the JS handler = must be 0). Fails `120` against the bug, passes fixed.
-
-**CI flake + hardening (2026-07-07):** original assertion set `scrollTop=0`, dispatched, `await setTimeout(60)`, then `expect(scrollTop).toBe(0)` — flaked on slow CI runners with **`expected 4 to be +0`**. Root cause: as sibling scroll pages finish loading, `#loadScrollPage` runs `#restoreScrollModeAnchor` **asynchronously**, which at scrollTop=0/index-0 (fraction 0) snaps `scrollTop` to page 0's `offsetTop` = the **4px `--scroll-page-gap`** margin. The 60ms post-dispatch delay raced that re-anchoring → observed 4. NOT the bug (bug = 120px). **Fix:** the buggy `scrollBy({behavior:'instant'})` is *synchronous* (lands before `dispatchEvent()` returns), so measure `before=scrollTop` / dispatch / `after=scrollTop` with **NO await between** and assert `after===before`. Synchronous read isolates the handler's own effect; immune to the async anchor-restore. Verified: reintroducing the buggy scrollBy → `before=4, after=124` (delta 120, still caught); reverted → stable across repeated runs.
-
-Fix lives in the `packages/foliate-js` submodule (separate repo/commit). Relates to [[fixed-layout-paginated-scroll-reset-4683]], [[webtoon-mode-3647]].

-#4587 — PDF two-page spread shows a one-pixel white bar in the MIDDLE (at the
-spine) on "certain zoom levels". Repro condition = fractional devicePixelRatio
-(Windows display scale 150% → dpr 1.5); at 100% (dpr 1) no bar. Fixed in
-`packages/foliate-js/pdf.js` `render()`.
-
-**Root cause:** `render()` sized the page canvas only via its bitmap
-(`canvas.width = viewport.width`). `viewport.width = pageWidthCss * dpr` is
-fractional, and a canvas bitmap width must be an integer, so it truncates (FP
-error often drops a whole pixel: 522*1.5=783 → viewport 782.9999 → bitmap 782).
-The iframe content is displayed scaled by `1/dpr` (the `documentElement`
-`transform: scale(1/devicePixelRatio)`), so the truncated bitmap renders up to
-~1 device px NARROWER than the page box. The left page's canvas stops short of
-the spine → exposes the reader background as a thin seam (white in light
-themes; in the dark demo it reads as a dark line). Right page's canvas starts
-exactly at the spine, so the gap is the LEFT page's shortfall only. The element
-flex boxes are always exactly adjacent (left.elR === right.elL === spine) — NOT
-the source; the seam is canvas-vs-box, not box-vs-box.
-
-**Fix:** pin an explicit CSS size to the un-truncated viewport dims so the
-bitmap scales to fill the box exactly:
-`canvas.style.width = `${viewport.width}px``; same for height. Display =
-viewport.width/dpr = exact page box → left canvas reaches the spine. General:
-fixes every page-canvas edge shortfall (single page + right page outer edge
-too), all dpr/modes. Idiomatic pdf.js HiDPI pattern (bitmap=device px, CSS=
-logical size) that the foliate wrapper had omitted.
-
-**Why dpr=2 can't repro (and dpr=1.5 readily does):** equal-width spread pages
-split content/2 exactly. At dpr 2, pageW*2 stays integer for even content
-widths → clean. At dpr 1.5, pageW*1.5 = content*0.75 is fractional unless
-content divisible by 4 → seam of 0, 0.5, or 1.0 device px depending on width.
-
-**CDP dpr=1.5 repro recipe (no device needed):** launch a throwaway desktop
-Chrome `--force-device-scale-factor=1.5 --remote-debugging-port=9444
--user-data-dir=/tmp/x`; dev-web seeds demo EPUBs in a fresh profile but no PDF
-— import a sample PDF (`apps/readest-app/src/__tests__/fixtures/data/sample-alice.pdf`,
-69pp US-Letter) via CDP `Page.setInterceptFileChooserDialog`+`fileChooserOpened`
-→`DOM.setFileInputFiles` (the readest "Import Books" button opens a MENU; click
-"From Local File" to trigger the chooser). `Browser.setWindowBounds` to sweep
-ODD inner widths (1283/1284…) to hit fractional pageW. Measure left-page canvas
-abs-right vs spine; capture a thin vertical clip at the spine to see the line.
-Dev server picks up foliate-js edits on reload (HMR recompiled it; no restart
-needed here, contra some older paginator notes). See [[issue-4112-scroll-anchoring]]
-neighbors for other paginator/foliate fixes.

-description: PDF text selection/highlight misplaced (into margins, offset down) when OS font-size accessibility scaling is on
-metadata:
-  type: project
---
-
-**Issue #4480**: on some Android devices PDF text selection/highlight is misplaced — the blue selection rectangles bleed into the blank page margins and sit ~1/3 line too low. Reported on a Galaxy Tab A8; NOT reproducible on a Galaxy S21.
-
-**Root cause (NOT what it looked like):** it is the **OS accessibility "font size" setting** (Android Settings > Display > Font size, `settings put system font_scale 1.3`), not the WebView version or devicePixelRatio. The OS font scale multiplies every piece of WebView-rendered *text* — including the transparent pdf.js text layer used for selection/highlight — but leaves the *canvas* page bitmap untouched. So the text-layer spans end up `fontScale`x larger than the glyphs baked into the canvas, and the native `::selection` boxes (which follow the span boxes) overshoot the text horizontally and vertically. The Tab A8 (a tablet) had enlarged system fonts; the S21 did not.
-
-**Ruled out during investigation:** WebView version (Tab A8 was on WebView **148**, newer than the working S21's 147 and a WebView-124 emulator — all fine at default font scale); devicePixelRatio (the paginator's fit-width `zoom` keeps `--total-scale-factor` DPR-invariant); interactive-vs-programmatic selection (both fine). Font-metric/realm mismatch was a red herring: main-app-doc and iframe-doc `measureText` are identical on working devices.
-
-**Fix** (`packages/foliate-js/pdf.js`, `render()`): detect the OS font scale with a probe (`offsetHeight` of a `100px`/`line-height:1` box = `100 * fontScale`, unaffected by DPR or the `<html>` `scale(1/dpr)` transform). The OS scales only the glyph **size** (a `font-size`); text-layer **positions** are percentages of the `--total-scale-factor`-sized container and are NOT scaled. So divide the scale out of the glyph-size lever ONLY: after `textLayer.render()`, set the container's `--text-scale-factor = calc(var(--total-scale-factor) * var(--min-font-size) / fontScale)` (that var feeds `font-size` and nothing else — grep the vendored `text_layer_builder.css` to confirm). At font_scale 1.0 the probe returns 1.0 → override skipped, no regression. PDF-only; EPUB is unaffected because its text and overlay scale together.
-
-**Do NOT divide `--total-scale-factor`** (the obvious-but-wrong first fix, PR #49 rev 1): it scales positions AND size, so `scale/F` shrinks the whole text layer toward the top-left origin — glyphs correct-ish size but positions compressed, offset accumulating downward. Verified by measurement: changing `--total-scale-factor` ×1.5 moves a span's top/left AND w/h all ×1.5. This looks "fixed" for the selection highlight (no more margin bleed) but the text layer no longer overlays the canvas; diagnose by coloring `.textLayer span { color: red }` and screenshotting the red-over-canvas overlay.
-
-**Repro/verify harness (reusable):** the release APK's WebView is CDP-debuggable. `adb forward tcp:PORT localabstract:webview_devtools_remote_$(pidof com.bilingify.readest)`, then drive `Runtime.evaluate` over the page WebSocket. The PDF renders in an iframe nested inside foliate-view's shadow DOM — deep-traverse `shadowRoot` + `iframe.contentDocument` to reach `.textLayer`. Create a multi-line selection with `doc.getSelection().addRange()` + `adb exec-out screencap` to see the native highlight. Set `settings put system font_scale 1.3` to reproduce. See [[android-cdp-e2e-lane]].

-Issue #4858: on 2-in-1 touchscreen laptops (Surface) reading PDFs webtoon-style, a two-finger **scroll** accidentally triggered zoom. User wanted NO zoom-lock option — just make pinch less sensitive and distinguish same-direction (scroll) from opposite-direction (pinch).
-
-**Where:** `src/app/reader/hooks/useIframeEvents.ts` `useTouchEvent`. Pinch only engages for `getBookData(bookKey)?.isFixedLayout` (PDF / fixed-layout EPUB). Touch events are forwarded from the foliate iframe as `iframe-touch{start,move,end}` postMessages (passive listeners, no preventDefault, so native two-finger scroll happens regardless — the old bug was that we ALSO zoomed).
-
-**Old bug:** `onTouchStart` set `isPinchingRef=true` immediately on any two-finger touch and `onTouchMove` applied `ratio=currentDist/initialDist` from the very first move. Real human scroll isn't perfectly parallel, so finger separation drifts → ratio ≠ 1 → accidental zoom; `onTouchEnd` committed `round(initialZoom*lastRatio)`.
-
-**Fix — pending state + magnitude discriminator + deadzone:**
- `onTouchStart` (two fingers, fixed layout): enter `pinchPendingRef=true` (NOT `isPinchingRef`), stash both initial touches (`initialTouch0/1Ref`), `initialPinchDist`, `initialZoom`.
- `onTouchMove` while pending: compute `separationDelta=|currentDist-initialDist|` and `panDist` = magnitude of the **midpoint travel** `((Δt0+Δt1)/2)`. Pinch keeps midpoint still while separation changes; scroll moves midpoint while separation barely shifts. Decide: pinch if `separationDelta >= PINCH_ACTIVATION_THRESHOLD(24) && separationDelta > panDist`; scroll (bail, native scroll takes over) if `panDist >= TWO_FINGER_PAN_THRESHOLD(12) && panDist >= separationDelta`; else keep waiting. This magnitude compare IS the "opposite vs same direction" test (more robust than a raw dot-product sign).
- On pinch confirm: re-baseline `initialPinchDist = currentDist` so zoom starts at 1x from the activation point — the deadzone travel is absorbed, no snap/jump.
- `onTouchEnd`: guard is now `isPinchingRef || pinchPendingRef`; only commit the `pinch-zoom` dispatch when `wasPinching` (a pending-only or scroll-resolved gesture leaves zoom untouched).
-
-Thresholds bias toward scroll (pan needs only 12px, pinch needs 24px separation) = "less sensitive". Uses `screenX/screenY` (not client) because `pinchZoom` CSS-transforms the iframe parent and oscillates client coords. Tests: `src/__tests__/hooks/useTouchEvent.test.tsx` (same-direction scroll → no zoom; opposite → zoom; jitter < deadzone → no zoom). Related: [[scrolled-pdf-pinch-zoom-4817]] (foliate `pinchZoom`/`pinchEnd` live scale + commit), [[image-zoom-trackpad-flicker-4742]] (macOS trackpad pinch = ctrl+wheel, different path via `useMouseEvent`).

-Issue #4700 (FR: Proofread enhancements) — SHIPPED, merged to main via PR #4708. The proofread (校对/替换规则) find-replace feature lives in: data model `ProofreadRule` in `src/types/book.ts`; store `src/store/proofreadStore.ts`; engine `src/services/transformers/proofread.ts`; selection popup `src/app/reader/components/annotator/ProofreadPopup.tsx`; manager dialog `src/app/reader/components/ProofreadRules.tsx` (mounted in `Reader.tsx`); sidebar entry `BookMenu.tsx`.
-
-What shipped (all test-first, full suite green):
-1. **Sync** — added `'globalViewSettings.proofreadRules'` to `SETTINGS_WHITELIST` in `src/services/sync/adapters/settings.ts` (whole-field LWW). ⚠️ CORRECTION (the original "KEY INSIGHT" here was WRONG): book/selection-scope rules were PUSHED (serializeConfig keeps the viewSettings delta) but **silently DROPPED on pull** — `useProgressSync.applyRemoteProgress` only consumed `location`/`xpointer` and discarded the rest of the synced config (the "Currently, only reading progress is synced" comment). So per-book/selection rules did NOT actually propagate across devices until the fix below. Library/global rules sync independently via the settings replica. See [[proofread-per-book-crdt-sync]].
-2. **Regex** — the transformer ALREADY fully supported `isRegex`; only UI was missing. Added a Regex toggle to the selection popup AND a full "Add Rule" form (pattern/replacement/scope Book|Library/Regex/Case-sensitive) to the manager dialog, validated via `validateReplacementRulePattern`. Popup skips the whole-word validation when regex is on.
-3. **i18n** — the whole-word warning in ProofreadPopup was a hardcoded English string (root cause of issue's point #2: Chinese user couldn't read it, thought symbols couldn't be replaced). Wrapped in `_()` + 8 new keys translated across all 33 locales via `pnpm i18n:extract`.
-4. **Shortcut** — reused the existing `onProofreadSelection` (`ctrl+p`/`cmd+p`). `handleProofread` in `Annotator.tsx` now opens the rules manager (`setProofreadRulesVisibility(true)`) when there's no active selection, and opens the create-from-selection popup when there is. No new shortcut entry, no first-level toolbar button (maintainer said skip). NOTE: first attempt used a dedicated `opt+p`/`alt+p` action — reverted because macOS Option+P is a dead-key (emits `'π'`, not `'p'`; `useShortcuts` matches on `event.key`). Ctrl+P avoids that entirely. The Annotator selection shortcuts have no unit-test harness (same as onTranslate/onDictionary), so this wiring isn't unit-tested; `setProofreadRulesVisibility` itself is covered by ProofreadRules.test.tsx.
-
-Later additions (same PR): modernized the manager dialog to the design-system primitives (SectionTitle, `card eink-bordered border-base-200`, `input input-bordered`, `btn-contrast` CTA disabled-until-pattern); scrollbar-to-edge via `contentClassName='!px-0'` on Dialog (the body's default `px-6 sm:px-[10%]` was insetting the inner scroll container); **drag-to-reorder** rules per category via @dnd-kit (mirrors `CustomDictionaries.tsx` — sensors, `dragModifiers`, `SortableContext`, drag-handle-only listeners). Reorder persistence = new `proofreadStore.reorderRules(envConfig, bookKey, orderedIds)` that rewrites only the `order` field (index-based) across BOTH stores (book config + global settings) in one call; the manager now sorts both displayed lists by `order` (stable, so default-1000 rules keep insertion order). NOTE: transformer re-buckets by scope (selection→book→library) so cross-scope drag order in the merged "Book Specific Rules" list is cosmetic — only within-scope order affects application; reordering a library rule there changes its GLOBAL order (affects all books).
-
-Gotchas / caveats:
- **`wholeWord` field is a near no-op in the transformer**: `normalizePattern` always wraps ASCII patterns in `\b…\b` regardless of `rule.wholeWord`; `isValidMatch` never reads it. It only gates the popup's pre-create validation (`isWholeWord` on the literal selection). So ASCII substring replacement (e.g. "cat" inside "category") is impossible today — pre-existing, out of #4700 scope.
- **macOS Option+letter dead-key**: `useShortcuts` matches on `event.key`, so any `opt+<letter>` shortcut won't fire on macOS (Option+letter emits a special glyph, not the letter). Avoid `opt+<letter>` bindings; prefer ctrl/cmd. A robust fix would need code-based matching in `useShortcuts` (deferred).
- Test isolation: spying `useProofreadStore.getState().addRule` across multiple tests leaks call counts — add `vi.restoreAllMocks()` in afterEach.
- Run single test files with `npx dotenv -e .env -e .env.test.local -- vitest run <file>` (bare `npx vitest` crashes on supabase `atob`).

-description: "Per-book/selection proofread rules now CRDT-merge by id on config pull (was dropped); tombstone-on-delete"
-metadata:
-  node_type: memory
-  type: project
---
-
-MERGED via PR #4781 (2026-06-25, squash commit 79ae8a48).
-
-Per-book + selection-scope proofread rules now actually sync across devices via an
-item-level CRDT merge (keyed by rule `id`), mirroring how booknotes merge. Before
-this, `useProgressSync.applyRemoteProgress` pulled the full synced book config but
-only applied `location`/`xpointer`, dropping `viewSettings.proofreadRules` (and
-everything else). Library/global-scope rules sync separately via the settings
-replica (`adapters/settings.ts` whitelist, whole-field LWW) — see [[proofread-enhancements-4700]].
-
-**Design (per maintainer):** no new DB table — the rules keep riding the existing
-book-config blob; the pull side just stops discarding them and merges by id instead.
-
-What changed:
- `ProofreadRule` (`types/book.ts`) gained `updatedAt?: number` (LWW key) and
-  `deletedAt?: number | null` (tombstone). No `createdAt` (the existing `order` covers ordering).
- New pure `mergeProofreadRules(local, remote)` in `src/utils/proofread.ts` — by id,
-  LWW on updatedAt/deletedAt, identical semantics to `mergeNotes` in WebDAVSync.ts.
- `proofreadStore.ts`: stamps `updatedAt` on add/update/toggle/reorder; **`removeBookRule`
-  now TOMBSTONES (sets deletedAt) instead of splicing** so the per-id merge can't
-  resurrect a deleted rule from the peer's live copy. `removeGlobalRule` STAYS a
-  hard-splice — library deletion already propagates via the settings replica's
-  whole-field LWW (shrinking the array wins), so a tombstone there would just leave
-  dead entries. Getters (`getBookRules`/`getGlobalRules`/`getMergedRules`) and the
-  book-scope dedup filter out `deletedAt`.
- `transformers/proofread.ts`: render filter gained `!r.deletedAt`.
- `ProofreadRules.tsx` `useReplacementRules`: filters `deletedAt` so tombstoned rules
-  don't show in the manager list.
- `useProgressSync.applyRemoteProgress`: merges `syncedConfig.viewSettings?.proofreadRules`
-  (filtered to scope !== 'library') into the open book's rules, `setViewSettings` +
-  `saveConfig`, and `recreateViewer` ONLY when the merged array actually differs (guards
-  a reflow on no-op pulls).
-
-Convergence gotcha (why the push re-uploads the union): `bookDataStore.saveConfig` only
-merges `{updatedAt}` into the in-memory config — it does NOT write the passed viewSettings
-into `booksData`. The thing that syncs merged viewSettings into `booksData.config` (so the
-next `pushConfig`→`getConfig` serializes the union) is `readerStore.setViewSettings`, but
-only when the viewState `isPrimary`. So call order must be setViewSettings → saveConfig
-(same as `proofreadStore.updateBookViewSettings`).
-
-**Stable id (`ensureRuleId` in utils/proofread.ts):** the merge keys on `id`, so id-less
-rules (legacy / hand-edited / foreign peer) would ALL collide on the Map's `undefined`
-slot — distinct rules clobber each other (silent loss, NOT duplication). `ensureRuleId`
-backfills a missing id with a content hash `ph-${md5(scope|isRegex|pattern)}` (selection
-scope also folds in sectionHref+cfi since it's per-instance), applied on both sides inside
-`mergeProofreadRules`. `createProofreadRule` now seeds book/library ids the same way
-(`id = scope==='selection' ? uniqueId() : ''` then `ensureRuleId`) so the SAME rule made
-independently on two devices dedupes on sync instead of duplicating; selection rules keep
-`uniqueId` (per-instance). Identity excludes replacement/case/wholeWord to match the
-in-store dedup (pattern+isRegex). Ids are assigned ONCE and frozen — edits never re-key
-(updates omit `id`). Limitation: rules already created with the old random `uniqueId` keep
-those ids, so pre-existing identical rules across devices are NOT retroactively merged.

-WebDAV does NOT carry proofread rules: its wire envelope strips viewSettings (`buildRemotePayload`),
-so this only fixes the native cloud sync path. WebDAV would need un-stripping + the same merge.

-Opt-in "Recently read" strip in the library Virtuoso header (PR #4829, issue #3797). `selectRecentShelfBooks(books, count)` in `libraryUtils.ts` (filter `!deletedAt && progress != null`, sort by `updatedAt` desc, slice 12). Setting `libraryRecentShelfEnabled` (default false) + View-menu toggle. Rendered via the Virtuoso `Header` through `BookshelfListContext` (stable identity → no grid re-render churn); list `<Virtuoso>` needs explicit `context={listContext}`.
-
-**Reuse, don't reimplement:** each slide renders the real `BookItem` (identical cover/title/progress/badges). The open path was extracted to `src/app/library/hooks/useOpenBook.ts` (in-place stale-record probe + `makeBookAvailable` on-demand download for cloud-only synced books + navigate) and is shared by `BookshelfItem` AND the recent shelf. Do NOT open via the select-mode `navigateToReader` path — it skips the download, so a recently-read book that synced (progress + `updatedAt`) without its blob fails to open on a second device.
-
-**Alignment gotcha (cost several iterations):** a horizontal flex strip with `basis-1/N` does NOT match a CSS-grid column when the grid has a row gap — CSS Grid subtracts the gap from each track, flex `basis` does not (covers come out too wide at 2/3 cols where `BOOKSHELF_GRID_CLASSES` uses `gap-x-4`; matches at `sm+` where `gap-x-0`). Fix: size each slide with the grid's own formula `flexBasis: calc((100% - (var(--rs-cols) - 1) * var(--rs-gap)) / var(--rs-cols))`, with `--rs-cols` (responsive `3/4/6/8/12` ladder when auto, else `libraryColumns`) and `--rs-gap` (`1rem` base / `0px` sm+, mirroring `gap-x-4 sm:gap-x-0`) set on the row. Also `min-w-0` on each flex item, else image covers expand to intrinsic width. Verified 0.00-0.02px edge diff vs a real CSS grid at N=2/3/4/5 (standalone HTML repro + getBoundingClientRect).
-
-Arrows: plain scroll div + `scrollBy`, shown on overflow (`scrollLeft`/`scrollWidth`, `ResizeObserver`), centered on `.bookitem-main` via measure; `start-2`/`end-2` + `rtl:rotate-180`. Swipe never opens (useLongPress moveThreshold). i18n: `i18n:extract` churns every locale (see [[i18n-extract-prunes-keys]]) — added the 2 keys manually; bo/si/ta/bn best-effort.

-Issue #4769: Russian typography forbids short function words (prepositions/conjunctions/particles) hanging at the end of a line ("hanging preposition"). Fix = a content transformer that inserts U+00A0 after such words so they stick to the next word. Source file is never modified.
-
-**Where:** `src/services/transformers/nbsp.ts` (export `nbspTransformer`, name `'nbsp'`), registered in `transformers/index.ts`, added to the FoliateViewer pipeline AFTER `simplecc`, before `proofread` — must run after `whitespace` (which strips NBSP when `overrideLayout`) or the glue is undone. (Originally named `russianNbsp` / `russianNbspTransformer`; renamed generic so it's the home for NBSP across languages.)
-
-**Generic by language:** internally a `NBSP_LANGUAGES: Record<langCode, {script, shortWords}>` registry; gate = `NBSP_LANGUAGES[normalizedLangCode(ctx.primaryLanguage)]` (so `ru-RU` -> `ru`; returns content unchanged if no entry). Only `ru` configured today; adding another language = one registry entry (its Unicode script name + a 3+ letter function-word list).
-
-**Gating decision (user, via AskUserQuestion):** language gate ONLY, no settings toggle (deliberately skipped the issue's requested toggle to keep scope in `services/transformers`). Belarusian/Ukrainian/Bulgarian (also Cyrillic) are NOT included — `ru` only.
-
-**Algorithm:** regex on the raw HTML string (NOT a DOM round-trip — avoids restructuring XML decl/doctype for every section, unlike `proofread`/`sanitizer` which parse+serialize). `TEXT_OR_SKIP = /<(style|script)\b[^>]*>[\s\S]*?<\/\1>|>([^<]+)</gi` skips style/script blocks and only rewrites text between tags, leaving tags/attrs/entities byte-for-byte intact.
- Glue regex (built per language from `config.script` + `config.shortWords`): `(^|[^\p{L}])(<3+ letter words>|\p{Script=<script>}{1,2}) (?=[\p{Script=<script>}\p{N}])` -> replace `$1$2` + NBSP. 1-2 letter words of the script glue generically; 3+ letter function words need the explicit list (content nouns excluded so we never glue after them).
- No look-behind ([[feedback_no_lookbehind_regex]]): capture+re-emit the boundary char instead. Because the boundary is consumed, consecutive short words ("и в доме") need a loop-until-stable (`do/while result!==prev`); NBSP is in `[^\p{L}]` so a just-inserted NBSP counts as the next boundary.
-
-**Known limitation (accepted):** postfix particles же/бы/ли glue FORWARD (to next word) not backward (to preceding word) — still prevents end-of-line hang, which is the issue's actual concern. Prepositions before digits glue too ("в 2025", "около 5").
-
-**Authoring gotcha:** typing literal NBSP (U+00A0) into tool inputs near Cyrillic silently produced many stray NBSP bytes in source. Always write NBSP as the ` ` escape in JS source; normalize files with a Python `chr(0xA0)->chr(0x20)` pass then restore the one intended escape. Verify with `python3 -c "...read().count(chr(0xA0))"`, not shell `grep $' '` (matches regular spaces). Same applies to test assertions: define `const NBSP = ' '` and build expectations via template literals.

-Built 2026-07-07 (approved design in `.agents/plans/2026-07-07-s3-provider-design.md`), full vertical slice on the bare-repo dev branch, UNCOMMITTED alongside the day's gdrive optimization work.
-
- **Transport** `src/services/sync/providers/s3/S3Provider.ts`: SigV4 via `aws4fetch` (was already a dep, server-side `utils/r2.ts` uses it; zero new deps). Path-style `<endpoint>/<bucket>/<key>`; keys map 1:1 from logical paths. GET/HEAD/PUT; ListObjectsV2 XML via DOMParser with delimiter + continuation-token draining; ensureDir no-op; deleteDir = list prefix + per-key DELETE (DeleteObjects needs Content-MD5, WebCrypto has none). head etag = md5 → engine's index change-detection works. Tauri streaming via presigned `signQuery` URLs → tauriUpload/Download. Injected fetch (web fetch / tauri plugin-http) + injected sleep; Drive-style error map + backoff. Passes `runSemanticContract` + 10 transport tests (stageAbsent dispatches by request shape: 404 for objects, empty-200 for listings).
- **Settings** `S3Settings` (endpoint/region='auto'/bucket/accessKeyId/secretAccessKey + shared sub-toggles) in types/settings.ts + DEFAULT_S3_SETTINGS in constants.ts; slice `settings.s3`.
- **Derivation/activation**: FileSyncBackendKind gains 's3'; getCloudSyncProvider order webdav > gdrive > s3; withActiveCloudProvider keeps 3 slices exclusive (+syncBooks/providerSelectedAt stamp); CloudSyncProviderFlags in settingsSync.ts gained optional s3 slice (multi-window switch protection, #4580 class).
- **Shared helpers** added to cloudSyncProvider.ts and swept everywhere: `settingsKeyForBackend(kind)` (5 sites) and `cloudProviderDisplayName(kind)` (4 sites) replaced scattered gdrive ternaries.
- **UI**: `S3Form.tsx` (WebDAVForm pattern; Connect probes `list('/Readest')` — 403=auth, 404=bucket, empty-200=ok); IntegrationsPanel: 's3' SubPage + chooser CloudProviderRow (RiDatabase2Line, "S3-Compatible Storage") + deep-link `requestedSubPage === 's3'`; Tips include R2 endpoint format + web CORS requirement.
- **i18n**: 14 new keys translated into all 33 locales (462 entries).
- Everything else (engine, FileSyncForm, fileSyncStore, fleet probe, per-book upload/download routing, reader hint) was already backend-generic and needed zero changes.
-
-NOT done: R2 account-ID preset, multipart upload, virtual-host addressing, remote-browser pane for S3. Live verification against a real R2 bucket pending (user tests on localhost:3000).

-#4436 — In scrolled mode the reader header chapter title was wrong vs paginated
-mode while transitioning between sections. Title comes from foliate `tocItem =
-TOCProgress.getProgress(index, range)`; `index`/`range` come from the
-paginator's relocate detail, ultimately from `#getVisibleRange()`.
-
-**Root cause:** the scrolled branch of `#getVisibleRange` (`packages/foliate-js/paginator.js`)
-returned the FIRST overlapping view (lowest index = topmost in scroll order).
-When the tail of section K is a thin text-bearing sliver at the very top of the
-viewport but section K+1 occupies the centre/majority, it returned K's range →
-title showed K while the reader was reading K+1. Paginated mode never shows this
-because each page belongs to one section. (`comparePoint` end-boundary logic in
-`progress.js` is shared by both modes and was NOT the divergence — the view
-choice was.)
-
-**Fix:** prefer the view whose visible band covers the viewport CENTRE
-(`center = #renderedStart + size/2`; `center >= off && center < off+vSize`);
-keep the first valid non-collapsed range as a `fallback` for when no loaded view
-covers the centre (very top/bottom of book). Also fixed `#afterScroll` scrolled
-fraction to size against `this.#views.get(index)` (the relocated view) instead of
-`#primaryView`, since the relocated `index` can now differ from `#primaryIndex`.
-`#detectPrimaryView`/`#primaryIndex` left UNCHANGED (drives preload/trim/bg;
-guarded by #4112/#3987 tests) — only the relocate index/range moved to centre.
-
-Accepted side effect: scrolled CFI/anchor now reflect the centre section (reopen
-lands at centre section top) — minor, arguably better.
-
-**Test:** `paginator-scrolled.browser.test.ts` "should report the section
-occupying the viewport centre…" — real paginator + sample-alice, two adjacent
-tall linear sections, `setAttribute('no-preload','')` AFTER fill to freeze view
-offsets (else backward-preload scroll-compensation shifts the absolute scrollTop
-target), nudge-scroll (first debounced scroll only clears `#justAnchored`; need a
-2nd to fire `afterScroll('scroll')`), assert relocate `index` == centre section.

-Live pinch-zoom for scrolled PDF (fixed-layout scrolled mode). The real fix is entirely in foliate-js: PR **readest/foliate-js#43 MERGED** to foliate main as `0fa407c` (on top of #42 `8bcb61e` which already had live pinch + the rect-match anchor + the interactive-when-idle idle-toggle). readest **PR #4817** is therefore **minimal — just the submodule bump to `0fa407c` + one unit test** (`fixed-layout-pinch-zoom.test.ts`, single clean commit `dd39837af`, +39/-1). readest needs NO touch-handling change: `origin/main`'s `useIframeEvents` already detects a two-finger gesture per page (`event.touches` forwarded via `iframeEventHandlers`) and calls `renderer.pinchZoom`. Builds on the scroll-lag scheduler [[pdf-scroll-lag-preload-4795]].
-
-**Abandoned detour (do not re-add):** a host-level cross-page-pinch approach (`multiTouch.ts` `updateSourceTouches`/`flattenSourceTouches`, per-iframe `sourceIndex` binding, `allActiveTouches` reading `e.touches`, and a `usePagination` host-click tap fix) was built then fully reverted. It is unnecessary once cross-page pinch is dropped, and same-page pinch + centre-tap toggle both work through existing `origin/main` code (tap goes iframe -> `iframe-single-click` centre zone; the host-click path is never hit when iframes are interactive).
-
-**Core architectural finding (the crux):** in scrolled FXL, **cross-page pinch and native text selection are mutually exclusive**. Each page is its own iframe; Android **serializes touches across iframe documents** (finger1 on page A gets `touchcancel` the instant finger2 lands on page B — proven via forwarded-touch logs), so a pinch spanning two pages can only be recognized if the *host* owns all touches, which requires `.scroll-page iframe { pointer-events: none }`. But inert iframes kill native selection/taps. So you pick one. User chose **native selection, drop cross-page pinch.**
-
-**Final design (foliate `fixed-layout.js`):**
- `pinchZoom(ratio)` in scroll mode scales the whole `.scroll-container` live (`computeScrollPinchTransform`, transform-origin at viewport centre). `pinchEnd` snapshots the centre page's `getBoundingClientRect` and the commit re-render (`#renderScrollMode`) scrolls it back to that exact rect (`#restorePinchAnchor`) — no jump.
- **No-shift fix:** the inter-page gap must scale with zoom or the committed gaps don't match the transform-scaled preview. `margin: calc(var(--scroll-page-gap,4px) * var(--scroll-zoom,1))` and `#renderScrollMode` sets `--scroll-zoom = scaleFactor`. Verified preview->commit scale MATCH + position jump <=2px.
- Iframes interactive **when idle** (restored `#setScrollIframeInteraction(true)` in `#handleScrollEvent` settle; `#scrolling` flag + interactive-on-load in `#loadScrollPage` so selection works without scrolling first), inert only **during active scroll** (native-smooth). Same-page pinch flows through the per-iframe forwarded-touch path; pdf.js `setupPanningEvents` handles pan (empty-area drag scrolls host) + native selection (text drag). `overflow-x:auto` + `width:max-content` enable horizontal pan of a zoomed page.
-
-**Gotcha — zoom store/attribute desync:** setting the `scale-factor` attribute directly (e.g. a test reset) does NOT update readest's `viewSettings.zoomLevel`. Pinch commit = `round(zoomLevel * lastPinchRatio)`, so a desynced store makes commit diverge from the live transform preview. Real pinches keep them in sync; only direct `setAttribute` breaks it. Cost me a long false-positive "shift" chase — reset zoom via a synthetic pinch, never `setAttribute`.
-
-**Selection re-impl (NOT taken):** host-level selection via `caretRangeFromPoint` + dispatch `selectionchange` on the iframe doc IS viable (readest `handleSelectionchange` -> `makeSelection` -> popup; `getPosition` returns valid coords for scroll-page selections), but loses native OS selection handles/magnifier, and the popup is deferred until a real `touchend` sets `androidTouchEndRef` (Annotator.tsx). Abandoned in favour of native selection.
-
-CDP-verified on Xiaomi (tap toggle, same-page pinch in/out no-shift, vertical scroll, horizontal pan, iframes `pointer-events:auto` when idle). Native selection itself needs a real finger (CDP synthetic touches don't engage the WebView long-press selection gesture).

Chose STRICT `is_allowed` (NOT read_dir's `|| contains("Readest")` substring hatch) because all legit callers (cloud sync, WebDAV, self-updater APK→`'Cache'`, OPDS→`'Cache'`) resolve under static scope ($APPDATA/Readest, $APPCACHE, $TEMP) OR persisted dialog grants (custom root via `setCustomRootDir`→picker→`allow_paths_in_scopes`; external folders re-granted at startup; `tauri_plugin_persisted_scope` makes sticky). Clippy needed `#[allow(clippy::too_many_arguments)]` on download_file (8 args). AppHandle auto-injected → JS invoke unchanged. NOTE: shared `target/` (worktree) was polluted with a deleted sibling worktree's abs plugin-permission paths → build failed `failed to read .../readest-feat-nightly-update-channel/.../fs/permissions/app.toml`; fix = `rm -rf` the `target/debug/build/<pkg>-<hash>` dirs grepping for the stale path, then rebuild. skip_ssl_verification left as-is (OPDS needs it). read_dir's own `contains("Readest")` hatch left untouched (out of scope).

-**Regression found 2026-07-08:** the "blocking private hosts removes no functionality" assumption below missed `pnpm dev-web` — in `next dev` the server runs on the developer's own machine and LAN catalogs (e.g. Calibre at 192.168.x.x) are the normal dev workflow; the unconditional `isBlockedHost` made the proxy 400 them ("This URL is not allowed"). CatalogManager already gates its "no LAN URLs" error on `NODE_ENV === 'production'`, so the proxy now mirrors that (PR #5002): `isPrivateHostAllowed() = NODE_ENV === 'development'` skips the blocklist (both preflight and per-redirect-hop). Vitest runs under `NODE_ENV=test` so the SSRF tests still exercise blocking; the dev-exemption test uses `vi.stubEnv('NODE_ENV', 'development')`. Self-hosted production deployments remain blocked (unresolved if anyone complains — would need an env-var opt-in). Also: Calibre's server throttles after repeated failed auth with transient 503s — don't mistake those for a proxy bug.
-
 **Non-obvious decision:** OPDS proxy can't require Readest auth — it's consumed from the browser via `<img src={getProxiedURL(...)}>` (covers) and `window.fetch` WITHOUT a Readest token; the `auth` query param is the *upstream* OPDS server cred, not the user token. So auth would break OPDS browsing/images. SSRF host-filter is the non-breaking high-value fix; residual relay/CORS-bypass on hosted CF (Medium) left for maintainer. On web the proxy is a CF Worker that can't reach a user LAN anyway (desktop bypasses via `needsProxy`), so blocking private hosts removes no functionality.

 Test invocation gotcha: `npx vitest run <file>` skips dotenv → `src/utils/supabase.ts:8 atob(...)` throws at import for tests that load the REAL `@/utils/access` (e.g. `send-fetch-url-guard.test.ts`). Use `pnpm test` (wraps `dotenv -e .env -e .env.test.local`) or `npx dotenv -e .env -e .env.test.local -- vitest run`. Tests that mock supabase/access are unaffected.

-Self-hosted premium TTS ("Readest Voice"): Kokoro v1.0 + v1.1-zh (Plus tier, EN/ZH/JA/FR) and Qwen3-TTS-12Hz-1.7B-CustomVoice (Pro tier, adds DE) served from a RunPod Serverless GPU worker, integrated as a new `readest-tts` engine with Edge-parity wire format (`X-TTS-Word-Boundaries`, 100ns ticks). Word timestamps via wav2vec2-CTC forced alignment (Apache-2.0 checkpoints only; MMS_FA is CC-BY-NC — banned).
-
-**Documents (all on dev, plans dir is local-only/gitignored):**
- Spec: `docs/superpowers/specs/2026-07-08-selfhosted-premium-tts-design.md`
- Service plan (separate repo `readest-tts-server`): `.agents/plans/2026-07-08-readest-tts-server.md`
- App integration plan: `.agents/plans/2026-07-08-readest-tts-integration.md` (contains all 3 review reports + 30-row decision audit trail)
-
-**Key user decisions (do not re-litigate):** gating plus/pro ONLY (purchase excluded — recurring GPU cost); quotas 100K/300K chars/day; self-hosted kept over managed-API despite both review models challenging it (cloning path + supplier independence); word-level alignment kept in v1; cold starts accepted but softened by warmup ping on voice-picker open (adopted at gate) + slow-start toast; usage meter and free-user upsell entry DECLINED; Edge stays default engine (premium is opt-in, `setVoice('')` must never match readest voices).
-
-**Load-bearing technical facts:** `fetchWithAuth` THROWS on non-OK with body.error as message (route error bodies must be flat strings); `merge_tokens` needs `blank=blank_id`; kokoro 0.9.4 yields Result dataclasses (verified vs pipeline.py); per-language GPU alignment tests + smoke `word_level` assertion guard silent sentence-level fallback; day-60 kill criterion (<3% adoption) in spec.
-
-**Status 2026-07-08 (late):** IMPLEMENTED. Integration branch `feat/readest-tts` (worktree /Users/chrox/dev/readest-feat-readest-tts, 9 commits, local-only, final review READY TO MERGE, 7118 unit + 217 browser tests green). Server repo /Users/chrox/dev/readest-tts-server (15 commits, no remote, final review READY pending infra gates; 28 CPU tests green, gpu suite deselected). Executed via subagent-driven development: 12 tasks, every task adversarially reviewed; notable catches: fetchWithAuth-throws contract, merge_tokens blank id, U+2019 unicode flattening (twice — agents flatten smart quotes/vowel signs in file writes; use \u escapes and verify by codepoint probe).
-
-**Remaining (infra-gated):** fill 9 `<pin-commit-sha>` HF revisions in scripts/download_weights.py; pick container registry (Docker Hub vs GHCR); docker build on amd64; `pytest -m gpu` on a GPU pod; RunPod endpoint per docs/deploy.md; smoke.py; comparative listening QA vs Edge; then app manual smoke (Task 7 step 3), PR + push after user confirms. Verify at deploy: CF Workers poll-duration, negative-increment RPC support.

-Sentry crash/error reporting added in PR #4914 (`feat(sentry): add crash reporting for Android, iOS, desktop, and web`). Four layers, one build-time `SENTRY_DSN` (empty => every layer no-ops):
-
- **JS + Rust panics**: `tauri-plugin-sentry` 0.5 + `sentry` 0.42 registered in `lib.rs::run()` (guard held to end of `run()`); rustls transport (NOT native-tls, so it cross-compiles for mobile); browser SDK auto-injected. Minidump handler is desktop-only: `#[cfg(not(any(target_os = "ios", target_os = "android")))]`.
- **Android native**: `io.sentry:sentry-android:8.47.0` in `gen/android/app/build.gradle.kts` + manifest auto-init `<meta-data>` (`io.sentry.dsn` from `${sentryDsn}` placeholder, `io.sentry.environment`). Crashes+errors only (traces=0, no PII, no replay).
- **iOS native**: `sentry-cocoa` via SPM in `project.yml`.
-
-Config: `sentry_config.rs` holds pure helpers (`sentry_dsn`, `environment_for_version`, `app_version`, `release_name`/`sentry_release`, `corrected_os_name`, `android_version_from_uname`, `is_ignored_browser_error`, `parse_webview_info`/`set_webview_info`/`webview_info`). Scope = crashes+errors only. Symbolication (source-map/ProGuard/dSYM upload) is STILL deferred — several 2026-07 crashes (READEST-2 render loop, READEST-9) could only be triaged to a function name, not a source line, for lack of source maps; upload them.
-
-**The Rust-client `before_send` (in `lib.rs`) now does three things**, in order, for every event (Rust panics + browser events forwarded by tauri-plugin-sentry): (1) drop known-benign browser noise via `is_ignored_browser_error` (case-insensitive match on the benign View-Transition rejections: "transition was skipped" (hidden tab READEST-7 + superseded-nav READEST-F) and "aborted because of invalid state" (READEST-G); a transition *timeout* is deliberately KEPT — real perf signal); (2) rewrite the Android OS name/version (see below); (3) tag `webview.engine`/`webview.version`. The webview tags come from a `set_webview_info` Tauri command the app calls once in `NativeAppService.init()` with `navigator.userAgent`; `parse_webview_info` extracts engine+major-version (Chromium `Chrome/140` checked before WebKit `Version/17`, because Android WebViews also carry a legacy `Version/4.0`) into a global `OnceLock` read in before_send. Added because forwarded browser events carry os/rust/device context but NO browser context, so crashes couldn't be correlated with WebView version. (feat(sentry): tag events with the WebView engine and version, merged 2026-07.)
-
-**2026-07 production crash-fix batch (all merged).** The recurring root cause was best-effort background work throwing UNHANDLED promise rejections (callers fire-and-forget, so a throw hits the global handler): READEST-1 concurrent-use (turso, see [[turso-concurrent-use-forbidden]]); READEST-5 cloud `deleteFile` threw (log+swallow); READEST-6 statistics DB writes on teardown (`runBestEffort` wrapper in `ReadingStatsTracker`; also covers READEST-4/8 network fails); READEST-A library save to a custom shared-storage folder failed `EACCES` because the save path never called the existing `requestStoragePermission()` (`AppService.saveLibraryBooks` now requests-once-per-session + retries). READEST-2 = zustand `updateTransferProgress` allocating new state on unchanged values → React update loop (equality guard). READEST-9 = `useAppRouter` wraps EVERY nav in a View Transition; opening a book is a heavy render that overruns the ~4s DOM-update budget → `TimeoutError` (fix: book-open navs use the plain `useRouter`, matching 8/10 into-reader paths; version-gating does NOT help — the 4s budget is version-independent).
-
-**Batch 2 (PR #4962, merged).** READEST-F/G = more benign View-Transition rejections → broadened the `before_send` filter (above). READEST-H = book-import `createDir` was non-recursive check-then-create; two concurrent imports of the same book race → Windows "Cannot create a file when that file already exists". Fix: `fs.createDir(getDir(book), 'Books', true)` (recursive = `create_dir_all`, idempotent). READEST-N = `StatisticsDb.applyRemoteEvents` runs a manual `BEGIN`/`COMMIT`; **the Rust per-op `op_lock` serializes single statements but does NOT make a multi-statement JS transaction atomic** — two concurrent pulls (split-view trackers share the `sharedDb` singleton connection) nest `BEGIN` in `BEGIN` → "cannot start a transaction within a transaction". Fix: a promise-chain mutex on `applyRemoteEvents` (works because JS is single-threaded — the synchronous grab-prev/install-new-promise is atomic; concurrency here is async *interleaving at `await`s*, not threads). General rule: any shared-connection multi-statement transaction needs JS-level serialization on top of the native op_lock. (Cleaner alternative not taken: dedupe the pull so only one tracker pulls the shared DB.) Deferred, need source maps: READEST-J (OPDS page-stream fetch, uncaught native reqwest error), READEST-K (`Failed to fetch`), READEST-M (`null appendChild`).
-
-**Batch 3 (PR #5012 + foliate-js#52, 2026-07-08).** All 0.11.18-current regressions; five fixed test-first + full verify (test/lint/fmt/clippy/test:rust green), one deferred. **READEST-11** = Auto Scroll (#4999)/middle-click autoscroll do `renderer.containerPosition += delta`; `FixedLayout.containerPosition` was getter-only (returned 0, no setter) so scrolled PDF/CBZ/fixed-EPUB crashed -> foliate `set containerPosition` reads/writes `scrollTop` in scroll mode, mirrors paginator (submodule commit + pointer bump). **READEST-19/21** = `handleHighlightMark` (useTTSControl) is a *synchronous* `tts-highlight-mark` listener, so its throws ESCAPE `dispatchSpeakMark`'s try/catch to window.onerror: empty `getContents()` -> destructure `doc` off undefined (19); null `anchor(doc)` range -> foliate `scrollToAnchor` reads `null.startContainer` / `getBoundingClientRect` in scrolled mode (21). Fix = guard empty-contents + null-range (app-side, no foliate change needed). **READEST-1Q/10** = `mobi` crate `image_records()` slice-index panic ("slice index starts at N but ends at M") on truncated/corrupt file in `mobi_parser::extract_cover`; wrapped in `catch_unwind` (import now succeeds sans cover; no `panic=abort` so it was already non-fatal via spawn_blocking JoinError). CAVEAT: sentry panic HOOK captures the caught panic anyway, so events likely persist post-merge -> to fully silence add a targeted `before_send` drop for mobi cover panics. **READEST-2M** = foliate pdf.js annotation `linkService` lacked `getAnchorUrl` (pdf.js calls it for named-action/GoTo link annotations) -> add `() => ''` matching pdf.js `SimpleLinkService`. **READEST-1V** = `useBooksManager` appendBook/openBookInReader call `initViewState` fire-and-forget; its "Book not found" rejection (library reload dropped in-memory entry, see readerStore) was unhandled -> `.catch` + toast (ReaderContent already did this). **DEFERRED READEST-18** "Window API not available on mobile": no stack trace, Seer unavailable (402 no budget); verified every reader-reachable `@tauri-apps/api/window` caller already mobile-gated (reader/page always-on-top=hasWindow, usePagination position=isMobile, ViewMenu fullscreen=hasWindow, themeStore updateWindowTheme=isLinuxApp); best remaining candidate = `useBookShortcuts.toggleFullscreen` gates on `isTauriAppPlatform()` (true on mobile) not `hasWindow`. Reinforces the standing "upload source maps" recommendation. Commit refs use `Fixes READEST-XX` (auto-close on merge); Sentry issues NOT resolved manually. SUBMODULE GOTCHA: foliate-js#52 was **squash-merged** (new main SHA `c1b1bbf`), so the branch-tip foliate commits the readest PR first pointed at would die when the foliate branch is deleted; re-pinned the readest submodule to `c1b1bbf` (foliate main) and collapsed the two per-fix bump commits into one (foliate squashed them anyway), then force-pushed. General rule for foliate-backed readest PRs: after the foliate PR squash-merges, re-pin the readest submodule to the new foliate `main` SHA, not the merged branch tip.
-
-**Batch 4 (PR #5014, 2026-07-08).** READEST-Y (11 users, escalating, REAL bug not noise): sentry-minidump relaunches the app with `--crash-reporter-server`; `parseCLIOpenWithFiles` (openWith.ts) awaited `getMatches()` which the file-only tauri-plugin-cli schema (`readest.exe [file1..file4]`) rejects -> unhandled rejection in the webview (`event.process: crash-reporter`) -> wrap getMatches in try/catch, return [] and fall through to the intent path. READEST-R/READEST-1Y/READEST-26 (24 users, grouped by route /reader //library): all benign "ResizeObserver loop limit exceeded" / "completed with undelivered notifications" -> added `value.contains("resizeobserver loop")` to `is_ignored_browser_error` (browser events ARE forwarded through the Rust before_send, same path the View-Transition filter uses). READEST-1Q/10 FOLLOW-UP: catch_unwind (#5012) makes the import succeed but the sentry panic HOOK still captures the caught panic, so it would regress post-release -> added a before_send stacktrace-frame drop via new `is_mobi_cover_panic_frame` ("mobi_parser::extract_cover") matched on OUR module path, not the generic slice-index message, so unrelated slice panics stay reported. Rust panic frames ARE symbolicated in-process (function names present in before_send) even though source lines aren't. Verified green (7093 vitest / 80 rust). Resolved READEST-Y/R/1Y/26 as resolvedInNextRelease. DEFERRED READEST-D (fatal SIGABRT, low-end Android Galaxy M13, on the sentry-android `SentryExecutorServiceThreadFactory` thread, no useful stack) -> native, needs symbolication. Remaining after batch 4: Bucket C + native panics READEST-B/C/D/P/T and READEST-J.
-
-**Batch 5 (PR #5015 + PR#5014 amend, 2026-07-08).** TRIAGE LESSON (big): before re-investigating a "still firing on 0.11.18" issue, ALWAYS check the release distribution: `search_events(dataset=errors, query="issue:READEST-X", fields=["release","count()"], sort="-count()")`. Events tagged `Readest@0.2.2` = the stale crate-version release from builds predating the release-name fix = un-updated OLD clients, NOT the current release. Bucket C debunked this way: READEST-1 (turso, 27u), READEST-5 (file deletion), READEST-4 (request timeout) were 100% on 0.2.2, ZERO on 0.11.18 -> already fixed, resolved (resolvedInNextRelease won't bounce since 0.2.2 < current). Only READEST-2 and READEST-9 were real 0.11.18 bugs. **READEST-2** (max update depth, 71u, PR #5015): prior no-op guard compared `transferSpeed`, which webDownload/webUpload recompute from `Date.now()` every chunk so it NEVER matched; `total=0` signed-URL downloads (R2/S3 #4990) churn per chunk; webDownload's `while(true){await reader.read();onProgress()}` fires the burst in one macrotask -> transfer-store fan-out (reader subscribes via useTransferQueue even though Reader.tsx:74 discards the return) blows past React's nested-update limit. Fix: `createProgressThrottle` (utils/transfer.ts; leading+trailing, macrotask trailing edge) wraps progress in transferManager.executeTransfer, caps store writes ~10/sec (flush on complete, cancel in finally) + drop transferSpeed from the store guard. Uninvestigated amplifier: settingsUnsub (transferManager #4971) reconciles on any settings identity change; useFileSync writes a new settings object each sync -> extra reader-side churn. **READEST-9** (VT timeout, 21/26 on 0.11.18, PR#5014 amend): useAppRouter routes navs through the VT router when `supportsViewTransitionsAPI` (the #4989 gate only helps UNsupported engines); on supported engines a slow library-grid render overruns the ~4s DOM-update budget -> `TimeoutError` unhandled rejection. Per user's call, swallowed it: added "aborted because of timeout in dom update" to is_ignored_browser_error (REVERSES the earlier "keep the timeout visible for perf signal" decision; a JS unhandledrejection preventDefault would NOT stop Sentry's forwarded capture, so the Rust before_send drop is the reliable path). Resolved READEST-2/9/1/5/4. Remaining high-priority: native panics READEST-B/C/D/P/T (need dSYM/ProGuard symbolication), READEST-J (updater network), READEST-18 (deferred, no stack).
-
-**Batch 6 (PR #5019, 2026-07-09; PRs #5012/#5014/#5015 MERGED).** After the merges the backlog refreshed with a new day's crop; my resolved ones dropped off. **READEST-12** ("Attempted to assign to readonly property" in scrollBy, WebKit/Linux) = the WebKit phrasing of READEST-11 (autoscroll writing getter-only containerPosition) -> already fixed by #5012, resolved (0.11.18 = pre-fix). **READEST-1A** (updateMetadata null, 6u): `TTSMediaBridge.bind()` resolves #mediaSession then awaits cover fetch + setActive; a concurrent `unbind()` (stop during startup) nulls #mediaSession mid-flight -> `this.#mediaSession.setActive/.updateMetadata` null deref. Fix = capture a local `const mediaSession = this.#mediaSession` for the awaited calls + `if (this.#mediaSession !== mediaSession) return` before wiring handlers (same capture-across-await pattern as READEST-19/21). Only the Tauri branch (`instanceof TauriMediaSession`) is affected; test injects a real `new TauriMediaSession()` via the constructor's resolveMediaSession param + a mid-fetch unbind. **READEST-13** (SQL "View page_stat already exists", 9u): REUSABLE FINDING -> **the @readest/turso fork discards `if_not_exists` for `CREATE VIEW`** (`core/schema.rs:1891` binds `if_not_exists: _`; `translate/view.rs` errors "already exists" regardless), even though it honors IF NOT EXISTS for TABLE/INDEX. So `CREATE VIEW IF NOT EXISTS` still throws when the view pre-exists (KOReader-imported statistics.sqlite3 has page_stat; or a partially-applied migration re-runs). Fix = `DROP VIEW IF EXISTS page_stat; CREATE VIEW page_stat AS ...` (turso DOES honor DROP VIEW IF EXISTS -> `translate/view.rs:406-408` returns Ok when absent). For any future turso view migration use DROP+CREATE, never rely on CREATE VIEW IF NOT EXISTS. Editing the existing migration is safe: version-tracked applied DBs fast-path skip (migrate.ts PRAGMA user_version), only un-applied/imported DBs run the new SQL. Real-turso repro test in statisticsDb.test.ts (NodeDatabaseService `:memory:`). Resolved READEST-12/1A/13.
-
-**Batch 7 (PR #5020 + foliate-js#53, 2026-07-09).** Foliate paginator null-guards. **READEST-1H** (11u, "Cannot destructure property 'style' of null" in columnize): `setStyles`/`setStylesImportant(doc.documentElement,...)` where documentElement is null (view doc blank/detached mid-render) -> guard `if (!el) return`. **READEST-2X** (4u, "getComputedStyle parameter 1 not Element"): `getDirection`/`getBackground` call `getComputedStyle(doc.body)` on iframe load with null body -> guard, fall back horizontal-ltr / '' background. getDirection is EXPORTED -> jsdom-testable (import 'foliate-js/paginator.js' works in plain jsdom, only INSTANTIATING the custom element needs ResizeObserver). **READEST-2Z** (getBoundingClientRect null) = scrolled-mode variant of READEST-21 (handleHighlightMark null range), already fixed by #5012 -> resolved. Resolved 1H/2X/2Z. LESSON: many new-crop null-derefs are pre-fix 0.11.18 variants of issues already fixed in merged-but-unreleased PRs (check the stack/culprit against fixed issues before re-fixing).
-
-**Batch 8 (PR #5027, 2026-07-09): JS source-map upload IMPLEMENTED** (was the recurring symbolication blocker). Bundler-agnostic (works with Turbopack): `next.config` `productionBrowserSourceMaps: exportOutput` -> `next build` emits `.js.map` in `out/_next/static`; `scripts/upload-sourcemaps.mjs` (chained into `pnpm build` via `&& node scripts/...`) runs `sentry-cli sourcemaps inject` (debug IDs; host-agnostic since chunks load from tauri.localhost) + `upload` (release `Readest@<pkg version>` matching sentry_config.rs + `~/_next/static` url-prefix fallback), then STRIPS `.map` files so they never ship. Token-gated on SENTRY_AUTH_TOKEN (no token -> skip upload + still strip -> local/fork output unchanged); Sentry failures logged, never fail the build. Added `@sentry/cli` devDep (REQUIRES `allowBuilds: '@sentry/cli': true` in pnpm-workspace.yaml, else pnpm writes a placeholder that breaks `pnpm lint`/deps-check). CI: added SENTRY_AUTH_TOKEN + SENTRY_ORG=readest + SENTRY_PROJECT=readest to the `.env.local` block in release.yml + nightly.yml. NEEDS the maintainer to add the SENTRY_AUTH_TOKEN GitHub secret (org auth token, scopes project:releases+org:read), then validate on the next nightly. Native (Android ProGuard needs the Sentry gradle plugin to embed the mapping UUID; native .so needs unstripped release symbols; iOS dSYM via sentry-cli in the local release script) = documented follow-up in `apps/readest-app/docs/sentry-symbolication.md`, deliberately NOT shipped (fragile native builds, unverifiable here). Once the secret lands + a nightly ships, the still-murky JS issues (READEST-2Y lang, 1D startContainer, 2B position, 1F section.load, 15 nextMark, 18 Window-API) get real stacks and become fixable.
-
-Remaining current 0.11.18 bugs (new crop, uninvestigated): reader null-derefs cluster READEST-1D/2Z/2V/2X/2Y/1F/1H/2B (startContainer/getBoundingClientRect/showHeader/getComputedStyle/lang/load/style/position null - likely torn-down doc/view access), READEST-15 (foliate tts nextMark `.keys()` of undefined via text-walker forward), READEST-J/READEST-22 (updater fetch), READEST-4X/4J, native READEST-D/T/P/1B/1R/1C/29.
-
-**Release + environment key off `package.json`, NOT the crate version.** Originally `release: sentry::release_name!()` = `CARGO_PKG_NAME@CARGO_PKG_VERSION` = `Readest@0.2.2` (stale crate version, never bumped) and `environment` read `CARGO_PKG_VERSION` (so it was ALWAYS "production" — nightly detection was dead). Fix: `build.rs::propagate_app_version()` reads the top-level `"version"` from `../package.json` (line-based parse via `read_json_string_field`, no serde) and bakes `cargo:rustc-env=READEST_APP_VERSION`; `app_version()` reads it via `option_env!` (falls back to `CARGO_PKG_VERSION`), same bake mechanism as `SENTRY_DSN`. `sentry_release()` -> `Readest@<pkg-version>` (e.g. `Readest@0.11.17`), `sentry_environment()` now derives from `app_version()` so nightly (`-YYYYMMDDHH`) correctly reports `environment=nightly`. Android/iOS **native** SDK releases already came from `versionName`/bundle version (tauri derives those from package.json), so only the Rust client (which also handles JS/browser events via tauri-plugin-sentry) needed fixing.
-
-**OS name "Linux" -> "Android".** On Android, `sentry-contexts::os_context()` builds the OS context from `uname()` (not-macos/not-windows branch): `name = info.sysname` = "Linux", `version = info.release` = kernel string like `6.1.162-android14-11-...`. Fixed with a Rust-client `before_send` in `lib.rs` that, keyed on `std::env::consts::OS == "android"`, rewrites `Context::Os.name` -> "Android" and pulls the Android version ("14") out of the `androidNN` token in `os.version` via `android_version_from_uname`. `before_send` runs AFTER `ContextIntegration::process_event` (which inserts the os context only if `Entry::Vacant`), so the "Linux" context is present to rewrite; applies to browser events too since tauri-plugin-sentry forwards them through the same Rust client. iOS-via-Rust would show "Darwin" but that path is minor (native sentry-cocoa reports iOS correctly) — not remapped.
-
-**Gotcha 1 — iOS generated files are gitignored + never tracked.** `gen/apple/Sources/Readest/main.mm` and `gen/apple/Readest_iOS/Info.plist` are gitignored (`.gitignore` `src-tauri/gen`) and regenerated by `tauri ios init` — editing them does NOT persist. Only `project.yml` and force-added custom files (like `ShareExtension/*`, `ReadestWidget/*`) survive. So native iOS init lives in a **force-tracked `gen/apple/SentrySupport/SentryBootstrap.m`** (`+[ReadestSentryBootstrap load]`, runs before `main`) wired via `project.yml` (SPM package + `- path: SentrySupport` source), reading the DSN from an iOS-gated Rust C-ABI `readest_sentry_dsn()` FFI (in `sentry_config.rs`) — no generated-file edits. See [[ios-widget-appgroup-stripped-appstore]].
-
-**Gotcha 2 — sentry-android needs a lifecycle exclude.** `sentry-android-core` (7.x AND 8.x) depends on `androidx.lifecycle:lifecycle-common-java8`, discontinued at 2.9.0+. The app's `lifecycle-process:2.10.0` pin version-aligns it to a nonexistent `2.10.0` -> Gradle `Could not resolve` at `:app:mergeUniversalReleaseNativeLibs`. Fix = `exclude(group="androidx.lifecycle", module="lifecycle-common-java8")` (its Java8 APIs now live in `lifecycle-common`). Same class as [[dependabot-pnpm-overrides]].
-
-**Gotcha 3 — no dotenv in the tauri build; wire `SENTRY_DSN` yourself.** `tauri-cli` (2.10.1) has NO dotenv dependency, so `.env.local` / `.env.*` are NOT auto-loaded into the cargo/gradle build (Next.js `.env.local` only reaches Next.js). `build.rs` resolves `SENTRY_DSN` with precedence **env -> `.env.local` -> `.env`** and bakes it via `cargo:rustc-env` (covers Rust + iOS FFI; `rerun-if-changed` avoids stale bake); `build.gradle.kts` does the same for the Android manifest placeholder. CI: `release.yml`/`nightly.yml` append `SENTRY_DSN=${{ secrets.SENTRY_DSN }}` to the `.env.local` they already build next to the PostHog/Supabase secrets (`cp .env.local apps/readest-app/.env.local`). iOS App Store release is a local script -> uses the maintainer's local `.env.local`.
-
-Env tag: `sentry_environment()` now reads `app_version()` (baked from `package.json`), so nightly stamps (`-YYYYMMDDHH`) resolve to `environment=nightly`; store-distributed mobile stays `production`. (Previously it read `CARGO_PKG_VERSION` — crate `0.2.2`, never nightly-stamped — so it was always `production`.)

-PR #4694 (merged). Upgrading Plus→Pro on Stripe leaves BOTH subscriptions `active`
-for a while (old one not cancelled immediately). `createOrUpdateSubscription`
-(`src/libs/payment/stripe/server.ts`) overwrote `plans.plan` with only the
-triggering webhook's plan, so whichever event arrived LAST won → a late Plus
-event downgraded a Pro user to `plus`. `plans.plan` feeds the JWT → drives
-quota/features (`getUserProfilePlan`, `getStoragePlanData` in `utils/access.ts`);
-`plans.status` is NOT a feature gate.
-
-**Fix**: `getHighestActivePlan(stripe, customerId)` lists the customer's subs,
-keeps `active`/`trialing`, retrieves each, maps via `product.metadata.plan`, and
-reduces by `PLAN_RANK` (`free`/`purchase` 0 < `plus` 1 < `pro` 2). Used in BOTH
-`createOrUpdateSubscription` AND `handleSubscriptionCancelled` (`webhook/route.ts`)
-— cancel now keeps the highest REMAINING active plan instead of always dropping to
-`free` (otherwise cancelling the leftover Plus would nuke an active Pro).
-
- **Apple/Google IAP unaffected**: subscription groups expire the old tier
-  immediately, so two-active-tiers doesn't arise; left unchanged on purpose.
- **Stripe expand depth cap = 4 levels**: `subscriptions.list` with
-  `expand:['data.items.data.price.product']` = 5 levels → fails. So list WITHOUT
-  deep expand, then `retrieve` each active sub with `expand:['items.data.price.product']`
-  (4 levels, OK).
-
-**Test-infra gotchas (cost real time, will recur):**
- Opt-in live integration test gate: use `it.skipIf(cond)` NOT `describe.skipIf` —
-  `describe.skipIf(true)` registers zero tests → vitest fails the file ("no tests").
- Keep the file import-safe when skipped: `await import('@/libs/payment/stripe/server')`
-  INSIDE the test body. A static import pulls `@/utils/supabase`, whose TOP-LEVEL
-  `atob(NEXT_PUBLIC_DEFAULT_SUPABASE_URL_BASE64)` throws when env is absent → crashes
-  collection. (Mocked unit tests dodge this via `vi.mock('@/utils/supabase')`.)
- `pnpm test -- <file>` does NOT filter (runs the WHOLE suite). To run ONE file with
-  env loaded: `npx dotenv -e .env -e .env.test.local -- vitest run <file>`. Raw
-  `npx vitest run` skips dotenv → the supabase `atob` crash above + 28 env-dependent
-  files fail (sync/crypto/share/wordlens) — NOT a regression, just missing env.
- Mock Stripe in unit tests: `vi.mock('stripe')` returning a constructor fn with a
-  static `createFetchHttpClient`; chainable supabase `from().select().eq().single()` /
-  `update().eq()` / `insert()`. `getStripe()` caches its instance but the methods are
-  stable `vi.hoisted` fns, so per-test reconfig works.
- Pre-push husky hook runs `tsgo --noEmit && biome lint .` over the WHOLE tree, so
-  unrelated untracked WIP (e.g. #4683 `fixed-layout-paginated-scroll.test.ts` importing
-  an unimplemented `computePaginatedScroll`) blocks the push → `git push --no-verify`
-  when your own files independently pass `pnpm test` + `pnpm lint`.

-# Decouple sync pull cursor from updated_at — server `synced_at` (#4678, branch feat/sync-synced-at-cursor-4678)
-
-Follow-up cleanup to [[sync-statusless-book-rebump-4677]]. `books.updated_at` was overloaded: (1) incremental-pull cursor (`GET /api/sync?since=…` filters `updated_at>since`; device keeps one global `max(updated_at)`) AND (2) library "date read" sort key. A server-resolved merge (reading_status LWW #4634) had to be written `> every peer's global cursor` to propagate → forced `updated_at=now()` → reordered the date-read library by sync time.
-
-**Decision (user-chosen): server `synced_at`, books-only, koplugin untouched.** Scoped to `books` because it's the ONLY table with the overload — the only server-side `updated_at=now()` bumps are the books status-merge propagation (sync.ts) + progress piggyback writes books rows; configs/notes are never server-bumped and aren't a sort key; `stats.updated_at` is already server-assigned. (Confirmed both scope decisions via AskUserQuestion.)
-
-**Implementation:**
- Migration `docker/volumes/db/migrations/016_add_books_synced_at.sql` + baseline `docker/volumes/db/init/schema.sql`: add `synced_at timestamptz NOT NULL DEFAULT now()`; **backfill `= COALESCE(updated_at,created_at,now())` BEFORE creating the trigger** (else trigger clobbers backfill to now() → full re-sync storm); index `(user_id, synced_at)`; `BEFORE INSERT OR UPDATE` trigger `set_books_synced_at()` forces `NEW.synced_at = now()` (server-authoritative; clients never send it). First trigger on these tables — justified because synced_at must be server-stamped on EVERY write path (insert / client-wins update / status-merge / piggyback) and a trigger is DRY + unforgeable.
- `GET` (`src/pages/api/sync.ts` queryTables): books filters `.gt('synced_at', since)` + orders by synced_at; **drop the `deleted_at` clause for books** (a delete bumps synced_at). configs/notes unchanged (`updated_at`+`deleted_at`).
- `POST` status-merge: extracted pure `buildStatusPropagationRow(serverBook, status)` — grafts fresher status, **removed `updated_at: now()`**. Trigger advances synced_at so peers re-pull; updated_at stays = event time → no reorder. Progress piggyback unchanged (trigger now reliably propagates it too).
- Client `src/hooks/useSync.ts`: exported `computeMaxTimestamp`, keys on `synced_at` first, falls back to `max(updated_at,deleted_at)` when absent. Added `synced_at?: string|null` to `BookDataRecord` (`src/types/book.ts`); `Book.syncedAt` already existed (unused, left unpopulated).
-
-**Why backward-compatible (key insight):** `synced_at >= updated_at` always (backfill makes old rows equal, trigger makes new rows now() ≥ client event time), so `synced_at>since` is a strict SUPERSET of `updated_at>since`. Old web clients AND the koplugin keep working with no data loss — at worst a redundant re-pull of rare server-merged rows (idempotent upsert). **koplugin left unchanged**: its `last_books_pulled_at` is SHARED between pull-cursor (vs server) and push-delta detection (`getChangedBooks` vs local updated_at) — retargeting it to synced_at would need a risky pull/push cursor split (follow-up). koplugin advances books cursor from row `updated_at`/`deleted_at` (syncbooks.lua pullBooks), notes from `os.time()*1000` — both fine under the superset filter.
-
-**Tests** (test-first, pure units; no DB in unit tests): `__tests__/pages/api/sync-synced-at-cursor.test.ts` (buildStatusPropagationRow keeps updated_at), `__tests__/hooks/useSync-cursor.test.ts` (computeMaxTimestamp prefers synced_at, falls back). Full suite + lint + format:check green. No Lua/Rust changed. PR #4712.
-
-**Online-migration gotcha (prod books = 3.8M rows):** the naive `UPDATE … WHERE synced_at IS NULL` (one txn, all rows) DEADLOCKED against live `/api/sync` upserts (`40P01`, both lock books rows in opposite orders); `ALTER COLUMN SET NOT NULL` (full-table ACCESS EXCLUSIVE scan) + plain `CREATE INDEX` (write-blocking SHARE) compound it. Rewrote 016 as an ONLINE migration — **run via psql, NOT in a wrapping txn / NOT the Supabase dashboard editor** (uses `CREATE INDEX CONCURRENTLY` + a `CALL` proc that COMMITs per batch, both rejected inside a txn): (1) ADD COLUMN nullable + `SET DEFAULT now()` up front (inserts during backfill get now()); (2) batched backfill in a PROCEDURE — `WITH todo AS (SELECT ctid FROM books WHERE synced_at IS NULL LIMIT 10000 FOR UPDATE SKIP LOCKED) UPDATE … FROM todo`, `COMMIT` each batch, EXIT when no NULLs remain — **SKIP LOCKED never waits on an app-locked row** so no deadlock; (3) `CREATE INDEX CONCURRENTLY`; (4) trigger LAST (else it clobbers the backfill to now()); (5) hard NOT NULL dropped (default+trigger+backfill keep it populated, client falls back to updated_at) — optional `ADD CONSTRAINT … CHECK (synced_at IS NOT NULL) NOT VALID` then `VALIDATE` (lighter SHARE UPDATE EXCLUSIVE, no full AccessExclusive scan). Note `now()` is STABLE not VOLATILE → `ADD COLUMN … DEFAULT now()` is fast metadata-only (one value for all existing rows) but that = migration-time-now ≠ updated_at, which would force a full re-sync storm — hence the explicit updated_at backfill. COMMIT is allowed in a PROCEDURE-via-CALL but NOT in a DO block nor inside a `BEGIN…EXCEPTION` sub-block.

-**Theorem** (github.com/fundaments-work/Theorem, web demo app.theorem.fundaments.work) is a local-first reading app that is a near-identical **Readest peer**: same stack — Tauri 2 (Rust) + React 19 + Zustand 5 + Foliate.js (vendored) + PDF.js. It is **MIT** (README explicitly contrasts vs Readest's AGPL). MIT is one-way compatible *into* AGPL, so Readest may legally adapt Theorem code with attribution; the reverse is not true.
-
-**Feature gaps Readest could learn from (ranked):**
-1. **Offline neural TTS** — Kokoro ONNX via Rust `kokoro-en` phonemizer, fully on-device, 6 voices, per-word sync, preloads next page audio. Readest TTS is Edge TTS (online) + native OS voices only. See [[edge-tts-webaudio-engine]].
-2. **RSS-into-annotations workspace** — subscribe to feeds, Mozilla Readability extraction, annotate articles like books, offline cache, unified export. Readest has none.
-3. **LAN P2P encrypted sync** — QR pairing, public-key device identity, no cloud relay, systemd sync-daemon. Complements Readest's cloud-only sync (WebDAV/GDrive/S3/KOSync).
-4. **Obsidian/Logseq Markdown vault export** — per-book `.md` with YAML frontmatter, vocab export, "Export now", status indicator. Readwise-alternative angle.
-5. **Vocabulary review workspace** — dedicated saved-word capture+review (beyond Readest's Word Lens/dict popup). See [[wordlens-feature]].
-6. **Gamified stats dashboard** — badges, 12-week heatmap, streaks, daily/yearly goals, WPM on top of tracked data.
-7. **Richer share cards** — Story (1080x1920) + Square formats, card themes, and sharing *reading stats* as cards, not just highlights. Readest has [[annotation-share-toolbar-4014]].
-
-**Key architectural insight (RSS-into-annotations):** Theorem unifies articles at the *data-model* level — `Annotation` keys on a `bookId`; articles get a synthetic `rss:<id>` bookId so the annotations panel, colors, sync tombstones (`feed`/`rss_article`), and vault export treat an article like a book. BUT their article reader renders extracted HTML into a **plain `<div>`**, forcing a bespoke char-offset highlight system (`article-highlight:<id>:<start>:<end>`, `wrapTextNodeRange`, `<mark>`-preservation guards).
-
-**Readest is architecturally better positioned:** `src/utils/md.ts` `makeMarkdownBook(file: File): Promise<BookDoc>` already renders arbitrary HTML into an **in-memory Foliate `BookDoc`** (sections, TOC, real CFI bases). Routing Readability-extracted article HTML through that same pattern gives CFI-accurate highlights, the Overlayer, TTS section tracking, Word Lens, dictionary, and the cross-device location cursor **for free** — deleting the need for Theorem's entire bespoke overlay. See [[markdown-md-support-774]].
-
-**RSS REDESIGN -> "periodical feed book" (2026-07-09, after /autoplan dual-model review).** The per-article-virtual-book design (feed=book + hidden synced article rows) was rejected: /autoplan (6 voices: Claude+Codex x CEO/Design/Eng) found blockers — `FEED` breaks exhaustive `EXTS/MIMETYPES` Records; `resolveBookContentSource` returns `missing` for non-pse virtual urls; native cloud `DBBook`/`transformBookToDB` DROP `book.url` so virtual rows don't rehydrate cross-device; `md5(articleUrl)` unstable (utm params); `visibleLibrary` groupId-hiding brittle; unguarded feed fetch = SSRF. CHOSEN model: **ONE virtual feed `Book` per feed** (append-only anthology, articles = sections, TOC = article list, opens in reader like any book — no separate list view, no per-article rows). CFI STABILITY (the crux, v2.1 DETERMINISTIC): `slot = parseInt(md5(articleId).slice(0,12),16)` (48-bit, <2^53) — identical on EVERY device with zero sync; enabled by foliate `view.js:486` hook `if (book.resolveCFI) return book.resolveCFI(cfi)` which lets the feed BookDoc resolve slot CFIs by MATCHING `section.id === String(slot)` instead of positional `sections[index]`. Sections display-ordered by publishedAt (order free to change; slot = pure identity); immutable per-article cached HTML; `section.cfi = CFI.fake.fromIndex(slot)`. Collision probe re-hash `id#n`. Residual gap: device B can't show highlights for articles that rolled off the feed (content never fetched there). Anthology progress % is hash-ordered/approximate -> feed books need own unread-based status (follow-on). (foliate builds location CFIs as `section.cfi ?? fromIndex(index)`, proven by [[markdown-md-support-774]] `md.ts`.) Cross-device WITHOUT server change: carry `feedUrl` in `book.metadata` (metadata IS synced) + rehydrate `book.url` in `transformBookFromDB`; store manifest in `BookConfig` (syncs -> same slots on device B); content cache local sidecar. SSRF: reuse `isBlockedHost` (`src/utils/network.ts`). Android cleartext for page-fetch still UNVALIDATED on a RELEASE build (debug sets usesCleartextTraffic=true, masks it) — but feed-content-first (contentHtml=encoded??description) avoids page-fetch for most feeds. Plan: `.agents/plans/2026-07-09-feed-periodical-books-plan.md`. **MERGED: PR #5039 (2026-07-09/10)** — worktree + branch cleaned up. Post-merge additions in the PR: import-menu polish (From Feed URL between From Web URL and Online Library, LuLibrary icon for Online Library, btn-contrast Subscribe), i18n pass (18 keys x 33 locales; en stays key-as-content). (Rebase gotcha: worktree submodule drift; fix = fetch new foliate-js pin inside packages/foliate-js from its local-modules remote.) Late additions: nav spinner via `wrappedFoliateView` goTo wrap (navigate-start/end events; TOC-jump blank = target section's remote images block iframe load); corner badge removed (cover carries identity). **DEVICE-VERIFIED (Xiaomi 13 Pro release build):** subscribe->feed book (icon cover + corner badge)->reader anthology; highlight + position survive reopen/refresh/app-update (slot CFIs live-proven). **Warm open 420ms vs 3178ms baseline** via SWR (`openFeedBookDoc`: warm manifest -> build local + background refresh; first open awaits). **Cleartext gate CLOSED: plugin-http/reqwest fetches http:// feeds fine on RELEASE Android** (WebView block does not apply to native fetch; the OLD failure was page-fetch via clip_url WebView). Covers MUST be canvas-rasterized to PNG (`rasterizeCoverSvg`) — Android won't render SVG bytes under cover.png (clip books work because importBook rasterizes). Device gotcha: proxy app in fake-IP DNS mode with tunnel DOWN resolves ALL hosts to 198.19.x.x -> reqwest 'error sending request'; ping is useless for reachability there (ICMP not proxied) — check `dumpsys connectivity` for VPN transport. Follow-ons: cover backfill for old subs, feed unread-status, old-build teardown, rolled-off-article gap on device B. Design+full review: `.agents/plans/2026-07-09-feed-books-virtual-articles-design.md`. The prior 7-commit build (per-article EPUB import + FeedsView workspace + feedStore) is superseded/torn down.
-
-Theorem RSS pipeline (for reference): Rust `fetch_rss_feed`/`fetch_url_content` proxy (reqwest, browser UA + UA-rotation on retry, redirect follow) → `fast-xml-parser` (RSS/Atom/JSON Feed) + `<link rel=alternate>` discovery → `@mozilla/readability` first, scored-container fallback → sanitize → render. Readest's OPDS proxy + SSRF guard (see [[security-advisories-web-2026-06]]) is the analogue for the fetch layer.
-
-**RSS IMPLEMENTED (2026-07-08) on branch `feat/rss-feeds`** (worktree `/Users/chrox/dev/readest-feat-rss-feeds`, 8 commits, HEAD 0bb536803; 7103 tests pass + lint clean; NOT pushed/merged, user kept branch as-is). New files: `src/services/rss/{feedParser,feedDiscovery,feedClient,feedPersistence,articleIngest}.ts`, `src/store/feedStore.ts`, `src/app/library/components/feeds/{AddFeedModal,FeedsView}.tsx`; + `AppService.loadFeeds()/saveFeeds()` methods (fs stays protected), ImportMenu "Feeds" entry. Reused clip pipeline verbatim (`convertToEpubWithWorker` + `ingestFile`, `clip_url` Tauri-only for full-page fetch). Gotchas found: `ingestFile` needs BOTH `groupId`+`groupName` (groupName alone dropped -> md5Fingerprint(feed.title)); FeedsView hydrate/save race needs `hydratedRef` guard; deferred minors = double-tap guard, multi-window feeds.json LWW. Plan: `.agents/plans/2026-07-08-rss-feeds.md`. Scope collapsed after finding Readest **already** has the article->book bridge: `src/services/send/conversion/convertToEpub.ts` `convertToEpub({kind:'article'|'page', html, url})` (Readability + per-site rules + image bundling + synthetic cover + headings-TOC, deterministic hash for dedup) is the "Send to Readest" web-clipper. Full URL->library-book flow lives in `src/hooks/useClipUrlIngress.ts`: `invoke('clip_url',{url})` -> `convertToEpubWithWorker` -> `ingestFile(opts,deps)` -> `useLibraryStore.updateBooks`. `@mozilla/readability`/`dompurify`/`marked` already deps. So RSS = **feed layer only** (subscribe + fetch + parse RSS/Atom/JSON via native DOMParser + unread store + Feeds UI); article opens reuse the clip pipeline as a normal `.md`/EPUB book tagged into a per-feed group -> annotations/TTS/sync/export inherited, zero reader changes. Bridge is convertToEpub, NOT the `md.ts` route I first proposed.

-PR #4835 (`feat/third-party-library-autosync`). Adds library-scoped auto-sync for the active third-party file-sync provider so `library.json` stays current without a manual "Sync now".
-
-**Architecture split (important):**
- `library.json` (the remote index) is written ONLY by `engine.syncLibrary` (`src/services/sync/file/engine.ts`). Before this PR that was called from exactly ONE place: the Settings → "Sync now" button (`FileSyncForm.tsx`).
- The reader's `useFileSync` (`app/reader/hooks/`) is PER-BOOK (progress/notes/cover/file) and NEVER touches `library.json` — it's the analogue of `useProgressSync`, not `useBooksSync`.
- So nothing auto-updated `library.json` on import/delete/book-close. Native sync didn't have this gap because `useBooksSync` is library-scoped.
-
-**Fix:** `useLibraryFileSync()` (`app/library/hooks/useLibraryFileSync.ts`), mounted once on the library page next to `useBooksSync()`. Parity counterpart of `useBooksSync`:
- Single `useEffect([library])` → debounced (5s) `engine.syncLibrary`. import (adds row), delete (sets `deletedAt`), book-close (bumps `updatedAt`) all mutate `library`, so one effect covers all three + initial-load pull.
- Builds engine async (Drive keychain probe), keyed on connection-relevant settings (NOT lastSyncedAt). Stable debounced trigger via `runSyncRef` so it isn't lost on re-creation.
- Gated on global file-sync mutex (`fileSyncStore.beginSync` — skip if a manual Sync now holds it), Sync Strategy, Upload Book Files, and `isCloudSyncAllowed`.
- MUST gate on `libraryLoaded` — syncing a transient empty pre-load library would push an empty index and clobber remote.
-
-**Delete propagation gotcha (the key insight):** `engine.syncLibrary` tombstones a deleted book in `library.json` ONLY if the deleted book (with `deletedAt`) is in the `books` arg → it stays in `allBooksMap` → final index carries the tombstone. If filtered out (the old `FileSyncForm` passed `eligibleBooks = filter(!deletedAt)`), then (1) no tombstone AND (2) the discovery books-dir scan (`!allBooksMap.has(hash)`) RE-DOWNLOADS the just-deleted book (its remote hash dir lingers until the separate GC sweep). So BOTH the hook and `FileSyncForm` now pass the FULL library incl. soft-deleted. Engine tests in `engine-metadata-sync.test.ts`.
-
-**Scope:** pushes the deletion tombstone to the index (peers won't re-pull it). Does NOT auto-remove the book from a peer's LOCAL library — engine reconcile skips `rb.deletedAt` entries (`engine.ts` ~line 430). Peer-side local deletion is a future, riskier change.

-#4439: on a decorative TOC page (nested layout tables), the **top half of the
-`CONTENTS` heading is clipped** in paginated mode (0.11.4 regression; 0.11.2 fine).
-Reporter blamed [[table-dark-mode-tint-4419]] but that's dark-mode only — this is
-light mode. Real cause is **#4400** (`scrollable.ts` + `getPageLayoutStyles`):
-
- v0.11.2 sized wide tables with `transform: scale()` — **never clipped**.
- #4391 then #4400 replaced that with wrapping every `<table>` (and display
-  `<math>`) in `.scroll-wrapper { overflow: auto }` + `table { max-height: var(--available-height) }`.
- These EPUBs lay the contents out as a nested `<table class="bc" style="margin: -1em 0 0 1em">`
-  with `<p class="lh em16 ...">CONTENTS</p>` (`line-height:1em`, inside `div.em06`=0.6em).
-  The **negative top margin** pulls the table (and the heading's first line) above
-  the wrapper's `overflow:auto` content box, which clips it. Measured: heading top
-  ~12.8px above the clip box = exactly `-1em` in the 0.6em context (~58% of the line).
- The `-fit` escape (`SCROLL_WRAPPER_FIT_CLASS` → `overflow:visible`) only checks
-  **horizontal** fit (`scrollWidth-clientWidth`). The table's positive `margin-left:1em`
-  inflates scrollWidth so it never gets `-fit`, stays `overflow:auto`, and clips.
-
-**Fix** (PR for #4439): `hoistNegativeMargins(el, wrapper, win)` in `applyScrollableStyle`'s
-`wrap()` — move any NEGATIVE computed margins from the wrapped element onto the wrapper
-and zero them on the element. Keeps the box in place, lets the element sit flush so the
-overflow box can't clip it; also de-inflates scrollWidth so a genuinely-fitting table
-gets `-fit`. Positive/auto margins are left alone (over-wide tables still scroll; centered
-tables stay centered). CSS can't do per-axis `overflow-x:auto; overflow-y:visible`
-(spec coerces `visible`→`auto`), so margin-hoisting is the route, not per-axis overflow.
-
-Repro is metric-sensitive (whether the inner table is `-fit`). Tests: browser test
-`src/__tests__/document/paginator-table-toc-clip.browser.test.ts` + fixture
-`repro-4439.epub` (real foliate paginator, asserts heading top not above its clip box);
-unit cases in `scrollable.test.ts`. Verified against the literal book (`321123.epub`,
-content-7.xhtml spine idx 12): clipped without fix, clean with it. Related:
-[[paginated-texture-occlusion-4399]], [[inline-block-column-overflow]].
