易良	796de4dfef	fix(core): merge IDE context into user prompt (#3980) ... * fix(core): merge IDE context into user prompt IDE mode now wraps editor context in a <system-reminder> block and prepends it to the current user request instead of inserting a separate user history entry via addHistory(). This preserves the API history turn shape and avoids extra user turns in IDE mode. Key changes: - IDE context merged into user request via prependToFirstTextPart() - State update deferred until after arena cancellation check - escapeClosingSystemReminderTags() hardens against tag injection including zero-width/control character variants - forceFullIdeContext reset on stream errors for correct resend - Context prompt updated to encourage active use of editor context Refs #3712 * fix(core): restore BaseLlmClient per-model cache clear on session reset resetChat only cleared GeminiClient's new perModelGeneratorCache but dropped the BaseLlmClient.clearPerModelGeneratorCache() call that was present before the refactoring. sideQuery.ts and sessionTitle.ts still route through BaseLlmClient with the fast model, so stale generators survived session reset. * refactor(core): remove duplicated per-model generator code from GeminiClient The per-model ContentGenerator resolution logic (resolveModelAcrossAuthTypes, createRetryAuthTypeForModel, createContentGeneratorForModel, perModelGeneratorCache) was inadvertently duplicated from BaseLlmClient into GeminiClient. This restores the original one-line delegation to BaseLlmClient.resolveForModel() and removes ~130 lines of redundant code to keep the PR focused on IDE context merging only. * fix(core): harden IDE context reminder escaping * fix(core): defer IDE context baseline update * fix(core): use shared escapeSystemReminderTags in tool scheduler Aligns the rule-activation envelope scrub with the IDE-context path — both now route through `escapeSystemReminderTags`, which neutralizes whitespace, zero-width, and control-character variants of `<system-reminder>` tag boundaries. The previous narrow regex only matched the literal `</system-reminder>` sequence, so a rule body containing `</system-reminder >`, `</ system-reminder>`, or `<​/system-reminder>` could still close the envelope mid-content. * docs(core): clarify request assembly order in IDE merge path Two adjacent comments described the pre-merge model: one called the system-reminder block "append" while the code prepends, and the tryCompressChat note still talked about "the previous context turn" which no longer exists once IDE context is merged into the user prompt. Rewrite both to match what the code actually does so future readers do not get a misleading mental model of prompt assembly or post-compression resend behavior. * docs(core): align scheduler scrub comment with shared helper The block-level comment still labeled the sanitization step as "closing-tag scrub", which described the old narrow regex. The shared escapeSystemReminderTags helper now neutralizes opening / self-closing / obfuscated variants too, so name the helper directly to keep the rationale and the call site in agreement. * test(core): cover escapeSystemReminderTags variants in scheduler The end-to-end scheduler scrub test only exercised a literal </system-reminder> body. Now that the rule-activation envelope routes through escapeSystemReminderTags, extend the integration coverage to the obfuscated closing-tag variants the helper was introduced to catch (whitespace before/after the slash, ZWSP / WJ / VS-16 inside the name) and to opening-tag injection. Each case asserts that the envelope still has exactly one </system-reminder> closer and that the raw obfuscated form (or unescaped opening tag) does not survive into the model-facing payload. Refactor the existing test's mock setup into a shared runSchedulerWithRule helper so the new it.each variants stay focused on the assertion shape. * fix(core): address remaining review feedback - Add debug log when IDE context parts are empty for diagnosability - Add safety comment in xml.ts explaining why no fast-path pre-check is used in getSystemReminderTagKind (zero-width obfuscation bypass)	2026-05-14 11:33:00 +08:00
ChiGao	3cc66f9ae5	ci(deps): bump docker/* actions to Node 24 majors (#4131) ... GitHub Actions deprecates the Node 20 runtime; older versions of every docker/* action run on Node 20 and emit the "Node.js 20 actions are deprecated" warning in every release / e2e / image-build run today. Each action shipped a "Node 24 as default runtime" major: - docker/setup-buildx-action v3 → v4 (2026-03-05) - docker/setup-qemu-action v3 → v4 - docker/metadata-action v5 → v6 - docker/login-action v3 → v4 - docker/build-push-action v6 → v7 None of our usages touch the deprecated inputs removed in the bumps — release.yml / e2e.yml call setup-buildx with no `with:` block, and build-and-publish-image.yml only passes the universally-supported `images` / `tags` / `registry` / `username` / `password` / `context` / `platforms` / `push` / `labels` / `build-args` inputs. ESM internal refactor of each action is transparent to consumers. Ratchet-pinned bumps use the v4.0.0 commit SHA `4d04d5d9486b7bd6fa91e7baf45bbb4f8b9deedd` (release.yml + e2e.yml). Other action references in build-and-publish-image.yml use `# ratchet:exclude` per existing convention, so version-string bumps suffice there. Verified runtime hosts (`actions/runner` v2.327.1+) are already in use on github-hosted runners as of 2026-03; no infra bump required.

顾盼	c512427f93	feat(core): strip inline media before chat compaction summary (#4101) ... * feat(core): strip inline media before chat compaction summary Compaction's side-query previously shipped historyToCompress verbatim. Two related issues degraded summary quality and accuracy: - Inline image / document bytes (from MCP tool results) leaked into the summary model's prompt where they could not be interpreted and merely inflated payload. - findCompressSplitPoint apportioned chars via JSON.stringify(content), so a single 1 MB base64 image looked like ~350K tokens and biased the split point. Real Qwen-VL token cost is at most a few thousand. This change adds a new compactionInputSlimming module that replaces inlineData / fileData parts with short [image: <mime>] / [document: <mime>] placeholders before the side-query, leaving live history unchanged. The same constant feeds estimateContentChars so the split-point algorithm sees the budget the summary model actually consumes downstream. Microcompact is also extended to clear stale inline images alongside old tool results. A previous draft of the design also externalized large pastes to a content-addressable on-disk cache, but it was withdrawn after surveying claude-code's 2026-03 to 2026-05 releases - upstream consensus is to keep user input visible to the model and amortize cost via prompt caching rather than externalize. See the Out-of-scope section of the design doc for the full rationale. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(core): recurse into functionResponse.parts when stripping media E2E exposed that `read_file` (and any tool that surfaces an image) wraps the result in `functionResponse.parts` via `coreToolScheduler.createFunctionResponsePart`. The slimming module only walked top-level `part.inlineData` / `part.fileData`, so the nested base64 bytes leaked into the compaction side-query payload. The previous design doc incorrectly claimed that no recursive walk was needed. Three changes: - `slimCompactionInput.transformPart` recurses into the nested `functionResponse.parts` array and replaces each entry via the same image/document placeholder logic. - `estimatePartChars` walks the nested array too, so the split-point algorithm doesn't fall back to `JSON.stringify` and over-count the base64 bytes. - `microcompactHistory` drops `functionResponse.parts` when clearing an old tool result; the previous spread of `...part.functionResponse` silently carried the original media through. New unit tests cover (a) nested image / document stripping, (b) the estimator no longer being skewed by nested base64. The previously failing E2E now PASSES: side-query payload contains zero `data:image/` occurrences, zero long base64 runs, and exactly one `[image: image/png]` placeholder. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(core): address review findings on compaction image stripping Addresses 8 valid findings from PR review: - [Critical] estimatePartTokens now handles `fileData` parts (both top-level and nested under functionResponse.parts). Without this, microcompact's `tokensSaved === 0` short-circuit silently discarded every fileData clear. - estimatePartTokens for binary parts now uses a fixed MEDIA_PART_TOKEN_ESTIMATE constant (1,600) instead of base64-length divided by 4. The old formula billed a 1 MB image as ~250K tokens rather than its actual ~1,280 visual tokens on Qwen-VL, inflating the saved-token metric by orders of magnitude. - mimeType values from MCP tool servers are now run through sanitizeMimeForPlaceholder before being embedded in `[image: …]` / `[document: …]` placeholders. An adversarial server could otherwise craft `image/png]\n\n[SYSTEM: …` and inject instructions into the summary side-query. - collectCompactablePartRefs now recognizes a third 'nested-media' kind: functionResponse parts from non-compactable tools (e.g. MCP screenshots whose names aren't in COMPACTABLE_TOOLS) that carry images on functionResponse.parts. The nested media is dropped while the tool's text output is preserved. Previously such media accumulated forever in live history. - keepRecent budgets are now per-kind (tool / media / nested-media). Setting `toolResultsNumToKeep: 1` keeps 1 of each kind rather than 1 entry total across the merged list — matches the natural reading of the setting name. - findCompressSplitPoint's `precomputedCharCounts` fallback path is now documented as test-only; production callers MUST pass the precomputed array. - The text-based branch of isAlreadyCleared is gone: with the new nested-media handling (drops `parts`) and existing media handling (replaces with `{ text: … }` that is no longer collected) it was unreachable. - OpenAI converter (createToolMessage) now passes text parts inside functionResponse.parts through as text content. The slimmer writes `{ text: '[image: image/png]' }` placeholders into the nested array; without this fix the converter dropped them when serializing to the OpenAI wire format, leaving the summary model with empty tool responses instead of the placeholder. Two findings deferred with rationale (see design doc Open Questions): MIN_COMPRESSION_FRACTION still uses pre-slim counts (acceptable — "user shared an image" is itself worth summarizing); SlimResult is not re-exported (round-3 simplify decided to keep core's public surface minimal). E2E re-verified end-to-end: side-query payload contains 0 data:image/ occurrences, 0 long base64 runs, and 1 `[image: image/png]` placeholder in the expected position. 185/185 collocated unit tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore(core): tidy compaction slimming after self-review Three small polishes from a follow-up code review pass: - `stripNestedMedia` no longer re-casts its return value: after destructuring `parts` out of the widened input type, TypeScript infers the original `FunctionResponse` shape without help. - `isAlreadyCleared` shed a 10-line comment block — the body is now one line, so one descriptive line above it is enough. - OpenAI converter's nested-part text check switched from `(part as { text?: unknown }).text` to `'text' in part && typeof part.text === 'string'`, dropping the cast and letting `in` narrow the type. No behavior change. 185/185 unit tests still pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(core): wire slim stats to debug log; split MicrocompactMeta tools vs media Addresses two follow-up review suggestions: - `slimCompactionInput` returned `stats.imagesStripped` and `stats.documentsStripped` but the orchestrator never consumed them. Now logged at debug level whenever non-zero so operators can confirm the slimming pipeline actually fires on image-heavy compactions. - `MicrocompactMeta.toolsCleared` lost meaning after the recent refactor: it had grown to count both tool-result clears AND inline-media / nested-media clears. Renamed: - `toolsCleared` → only `tool`-kind clears (compactable tool output) - `mediaCleared` → `media` + `nested-media` clears (new) - `toolsKept` / `mediaKept` mirror the split, replacing the prior `toolsKept` that was actually a combined count. The single non-test consumer (`client.ts` debug log) updated to use both fields. 185/185 unit tests pass.

tanzhenxin	f72a156e13	fix(anthropic): allow cache_control on tool_result blocks so the per-turn breakpoint advances (#4121) ... The Anthropic adapter places three cache_control breakpoints (system, last tool, last user message), but `addCacheControlToMessages` only attached the third when the last block of the last user message was a non-empty text block. After turn 1 of any agentic conversation, the last user message is a tool_result, so the breakpoint was silently dropped and the cacheable region collapsed back to system+tools. Per-turn history was never cached. Anthropic's docs explicitly list tool_result as a cacheable block type (https://docs.claude.com/en/docs/build-with-claude/prompt-caching). Accepting both text and tool_result keeps the breakpoint moving forward as the conversation grows.	2026-05-14 10:07:11 +08:00

John London	93c5ce162f	fix(search): make empty-query exit synchronous and normalize Windows Backspace (#3981) ... * fix(search): make empty-query exit synchronous and normalize Windows Backspace Two fixes to useSessionSearchInput that caused 'Backspace edits the query; emptying it returns to list mode' to fail on Windows: 1. Replaced the useEffect-based onExitToList mechanism with a ref-backed setSearchQuery that detects the non-empty → empty transition synchronously inside the state updater. The previous useEffect approach introduced a one-frame delay where the component rendered in search mode with an empty query before the effect fired, causing the 'Press / to search' hint to be absent on Windows. 2. Added isDeletionKey() helper that recognizes Backspace from both the key.name field ('backspace'/'delete') and the raw sequence bytes (\x7f DEL and \b BS), so Windows terminals that deliver Backspace without normalizing the key name are handled correctly. Generated by Mistral Vibe. Co-Authored-By: Mistral Vibe <vibe@mistral.ai> * fix(search): address review feedback on PR #3981 - Update onExitToList JSDoc: describe synchronous ref-backed detection instead of stale useEffect reference - Update test suite comments: replace useEffect references with ref-backed setter description - Add assertion that implicit entry (empty→non-empty via setSearchQuery) does NOT trigger onExitToList - Add tests for Backspace/Esc/Ctrl+U/Ctrl+L on already-empty query: must not trigger onExitToList * fix(search): address remaining review feedback on PR #3981 - Add isDeletionKey byte-fallback tests (\x7f DEL and \b BS) - Update setSearchQuery JSDoc to document synchronous onExitToList side-effect - Stabilize callback deps: read onExitToList via ref so setSearchQuery and handleSearchKey are not recreated on parent re-render - Clarify onExitToList JSDoc: fires before React re-renders, ref is current but state variable is stale - Add test for setSearchQuery('') direct-empty path (non-empty → empty) - Add test for setSearchQuery('') on already-empty query (no spurious exit) * test: stabilize flaky export format cycling test on Windows CI Increase wait from 50ms to 350ms after typing '/export md' to allow the useEffect in useExportCompletion to fire and set cyclingActiveRef before the Down keypress arrives. This matches the pattern used by other tests in this file that depend on useEffect timing. * fix(search): guard isDeletionKey byte fallback against ctrl/meta modifiers The byte fallback in isDeletionKey (key.sequence === '\x7f' / '\b') previously fired even when ctrl or meta modifiers were active. Ctrl+H delivers name:'h', ctrl:true, sequence:'\b' on many terminals and was incorrectly treated as Backspace, deleting the last query char. Add !key.ctrl && !key.meta guard so the byte fallback only activates when the terminal truly did not normalize the key name. Also add two tests: - Ctrl+H (BS byte with ctrl) must not be treated as deletion key - Meta+DEL byte must not be treated as deletion key --------- Co-authored-by: Mistral Vibe <vibe@mistral.ai>	2026-05-14 09:03:16 +08:00
ChiGao	d343e2c15e	feat(perf): progressive MCP availability — MCP no longer blocks first input (#3994) ... * feat(perf): progressive MCP availability — MCP no longer blocks first input Today `Config.initialize()` runs MCP discovery synchronously and the cli can't accept input until every configured MCP server finishes its discover handshake. One slow or hung server bottlenecks every user with MCP configured. Validated by the profiler instrumentation added in this PR (set `QWEN_CODE_PROFILE_STARTUP=1` to reproduce): | User scenario | Time to first prompt input | | ------------------------- | -------------------------- | | No MCP | ~480 ms | | 1 fast MCP | ~875 ms | | 2 fast + 1 slow MCP | **~7.1 s** | | 1 hung MCP server | **~10.5 s** | (Measured on macOS arm64 / Node 24.15, n=30/fixture, p50.) `Config.initialize()` now passes `{ skipDiscovery: true }` to `createToolRegistry` by default and kicks off MCP discovery in a fire-and-forget background path. As each server completes discover, the cli's `AppContainer` debounces `setTools()` calls into one-frame (16 ms) batches so the model sees the consolidated tool list shortly after each server settles. Rollback: `QWEN_CODE_LEGACY_MCP_BLOCKING=1`. - `packages/core/src/config/config.ts` — `Config.initialize` switches to `skipDiscovery: true` + new `startMcpDiscoveryInBackground()` (defensive against partially-stubbed `ToolRegistry` in tests). Adds `MCPServerConfig.discoveryTimeoutMs` (last positional ctor param — doesn't shift existing call sites). Tool-call timeout is untouched. - `packages/core/src/tools/tool-registry.ts` — new `getMcpClientManager()` getter so the background path can call the incremental discover directly without going through `discoverMcpTools` (which would wipe already-registered tools). - `packages/core/src/tools/mcp-client-manager.ts` — `discoverAllMcpToolsIncremental` now: emits `mcp-client-update` after IN_PROGRESS transition, wraps each per-server discover in a discovery-only timeout (stdio 30s, remote 5s), emits trailing `mcp-client-update` after COMPLETED so UI subscribers see the terminal state. - `packages/cli/src/ui/AppContainer.tsx` — new `useEffect` (gated on `isConfigInitialized`) subscribes to `mcp-client-update` and 16ms-batches `setTools()` calls. Same effect also defers `finalizeStartupProfile` until MCP settles (or 35s hard cap), so startup-perf profiles capture the full MCP timeline. Activated only by `QWEN_CODE_PROFILE_STARTUP=1`; when unset every profiler entry point short-circuits in a single null/flag check and returns. Heisenberg overhead measured at -1.12% Δp50 between profile-on vs profile-off (Welch p=0.092, n=30/config × 3 configs) — within statistical noise. - `packages/cli/src/utils/startupProfiler.ts` — extended with `events` array (multi-fire), `recordStartupEvent`, `setInteractiveMode`, `derivedPhases`, per-checkpoint heap snapshots, `MAX_EVENTS` cap, and `QWEN_CODE_PROFILE_STARTUP_OUTER` / NO_HEAP env opt-ins. + 7 new tests. - `packages/core/src/utils/startupEventSink.ts` (new) — minimal cross-package sink so `core` can emit profiler events without reverse-depending on `cli`. No-op when no sink registered. + 4 tests. - `packages/core/src/index.ts` — export `setStartupEventSink` / `recordStartupEvent` / type aliases. - `packages/cli/src/gemini.tsx` — registers the sink at `main()` entry, adds `first_paint` checkpoint after Ink render, calls `setInteractiveMode(true)` in the interactive branch. - `packages/core/src/config/config.ts` — emits `tool_registry_created`. - `packages/core/src/core/client.ts` — emits `gemini_tools_updated` at the end of `setTools()`. - `packages/core/src/tools/mcp-client-manager.ts` — emits `mcp_discovery_start`, `mcp_server_ready:<name>`, `mcp_first_tool_registered`, `mcp_all_servers_settled`. - `packages/cli/src/ui/AppContainer.tsx` — emits `config_initialize_start`, `config_initialize_end`, `input_enabled`. `Config.initialize()` now returns BEFORE MCP discovery completes. Things to check: - Any code path that assumed "after `config.initialize()`, all MCP tools exist in the registry" — these will see only built-in tools initially; new tools appear via `mcp-client-update` events. - `MCPDiscoveryState.COMPLETED` is now set asynchronously instead of synchronously after `initialize()` resolves. - Model requests issued before MCP settles see only built-in tools; subsequent requests see the full set as servers come online. - Tests that assert MCP tool count immediately after `config.initialize()` should wait for the `mcp-client-update` with COMPLETED discoveryState instead. - 313 impacted-area tests green (config / mcp-client-manager / client / startupProfiler 18 / startupEventSink 4). - `tsc --noEmit` clean for `packages/core` and `packages/cli`. - `eslint` clean on touched files. - Manual: `QWEN_CODE_PROFILE_STARTUP=1 SANDBOX=1` interactive run produces a JSON profile in `~/.qwen/startup-perf/` containing `first_paint`, `config_initialize_start/end`, `input_enabled`, MCP per-server events, and `gemini_tools_updated`.

Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(core): harden progressive MCP discovery against silent regressions Addresses review feedback on PR #3994: - Skip user-disabled servers in discoverAllMcpToolsIncremental. The new incremental path used to iterate Object.entries(servers) without consulting isMcpServerDisabled, so a server the user had explicitly turned off would still get connected and its tools registered. Mirrors the existing protection in discoverAllMcpTools. - Disconnect the underlying client when runWithDiscoveryTimeout fires. Without this, the inner discoverMcpToolsForServer kept running after the timeout rejected the outer promise — if discover() eventually succeeded it would register the late server's tools into the live toolRegistry (a silent registration vector, especially exploitable with a 0/negative discoveryTimeoutMs override). - Clamp discoveryTimeoutMs to [100ms, 300_000ms]. 0/negative/Infinity values previously passed through to setTimeout unvalidated and made the silent-registration bug above trivially reachable. - Classify the `tcp` (WebSocket) transport field as remote so hung WS handshakes use the 5s default instead of the 30s stdio default. - Defensive delete of serverDiscoveryPromises[name] in the per-server catch so a doomed/orphan entry can't briefly short-circuit a subsequent discoverMcpToolsForServer call. Adds focused tests for each fix. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(cli): restore runtime.json sidecar and harden non-interactive MCP visibility Addresses review feedback on PR #3994: - Restore writeRuntimeStatus + markRuntimeStatusEnabled in startInteractiveUI. The progressive-MCP diff inadvertently dropped the runtime.json sidecar write from the interactive entry point, leaving Config.refreshSessionId()'s session-swap refresh as dead code and silently breaking external integrations (terminal multiplexers, IDE integrations, status daemons) that map PID → sessionId via runtime.json. - Add Config.getFailedMcpServerNames() and surface a stderr warning in --prompt / stream-json / ACP entry points when one or more MCP servers failed during background discovery. Per-server errors are caught inside discoverAllMcpToolsIncremental and never reached a TTY otherwise, so a script using non-interactive mode with broken MCP config would silently run with only built-in tools — a regression vs the legacy synchronous path. - Pass the parsed `settings` object through to runNonInteractiveStreamJson. The new call site dropped the argument, falling back to createMinimalSettings() and losing any user-configured permission / approval / hook setup for stream-json sessions. Added regression assertion to gemini.test.tsx. - Move finalizeStartupProfile out of gemini.tsx's stream-json branch and into Session.ensureConfigInitialized so it runs AFTER config.initialize() / waitForMcpReady() in stream-json. Previously the profile was finalized before any MCP / config_initialize_* events were emitted, producing empty stream-json profiles. - Gate setStartupEventSink registration on isStartupProfilerEnabled() so core-side recordStartupEvent calls short-circuit at the first null-check when profiling is disabled, instead of going through an arrow wrapper and the profiler's own enabled gate. - Tighten the type-unsafe ToolRegistry cast in startMcpDiscoveryInBackground to preserve the typed return signature so a rename of getMcpClientManager would be flagged at this call site (kept the optional-chain guard for tests that stub ToolRegistry as a plain object). - Re-document first_paint as "render call returned" so consumers don't confuse Ink's synchronous render() return with literal pixel paint. Kept the checkpoint name for backward compatibility with collected profiles. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(cli): restore resize repaint and pin gemini_tools_lag capture in AppContainer Addresses review feedback on PR #3994: - Restore the terminal-resize useEffect that calls repaintStaticViewport() when terminalWidth changes. The progressive- MCP diff removed previousTerminalWidthRef + the repaint useCallback + the resize useEffect, so tmux pane resizes and fullscreen toggles leave the static region rendered at the old width — header content visibly tears until something else triggers refreshStatic. - Pin the gemini_tools_lag startup metric. The previous onMcpUpdate handler called finalizeOnce() synchronously when discovery reached COMPLETED, but the pending setTools() batch was still 16ms away. setTools() emits `gemini_tools_updated` — when finalize ran first the profile's `finalized` guard suppressed that event, so gemini_tools_lag came out undefined in interactive mode. New onMcpUpdate flushes setTools() NOW on COMPLETED and only finalizes after the flush resolves, guaranteeing the event lands. - Log setTools() batch-flush errors via debugLogger instead of silently swallowing them. GeminiClient.setTools() has no try/catch around warmAll() / getFunctionDeclarations() / getChat().setTools(); the previous `.catch(() => {})` would have hidden production tool-registration regressions completely. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(core): correct MCP failure visibility and incremental cleanup Addresses three review findings on PR #3994: - McpClient.discover() now flips the client status to DISCONNECTED before re-throwing. Previously, a server that connected successfully but whose discoverPrompts / discoverTools then rejected (or that returned no prompts and no tools) would remain CONNECTED in the global status registry. Config.getFailedMcpServerNames() filters by `status !== CONNECTED`, so such servers were silently omitted from the non-interactive failure banner and the Footer's MCP health pill kept counting them as healthy. - discoverAllMcpToolsIncremental no longer records `outcome: 'ready'` for servers whose connect/discover threw. The inner discoverMcpToolsForServerInternal catches errors without re-throwing (best-effort discovery semantics), so the try block resolved even for failures — only the runWithDiscoveryTimeout path reached the catch. Auth errors, server crashes, and missing-tools responses were therefore recorded as success in the startup profile. We now consult the actual server status (now correctly DISCONNECTED after the first fix) before emitting `ready`, and emit `outcome: 'failed'` otherwise. `mcp_first_tool_registered` is gated on the same check so a failed server can't pollute that user-facing metric. - discoverAllMcpToolsIncremental tears down enabled→disabled mid-session transitions. When a previously-connected server is disabled (e.g. via `/mcp disable foo` or by editing settings), the incremental path used to just `continue` past it, leaving its client, tools, health check, and global status entry in place. Now calls removeServer() for any already-known client we encounter in the disabled branch. Adds focused tests for each fix. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(core): clarify ToolRegistry cast comment in startMcpDiscoveryInBackground Addresses review feedback on PR #3994. The previous comment claimed the call site uses "no defensive cast" but the code still casts via `as ToolRegistry & { getMcpClientManager?: ... }`. Reword to explain the cast's actual purpose: it exists only because some tests stub ToolRegistry as a plain object, so we use optional chaining to avoid crashing the init path when those tests run. Also note that the inner shape now uses `ReturnType<ToolRegistry['getMcpClientManager']>` — a future rename of the production method still surfaces as a type error at this call site rather than silently falling through to the `if (!manager)` branch. Comment-only change; no behavior diff. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(core): close MCP timeout TOCTOU race and propagate disconnect status Addresses two critical findings on PR #3994 round 6: - runWithDiscoveryTimeout no longer uses fire-and-forget disconnect. The prior `void client.disconnect()` returned before `transport.close()` landed, leaving a window where an in-flight `discover()` could pump `tools/list` through the transport and synchronously register tools into the live registry BEFORE the close took effect. The earlier fix comment described this as a "remote-exploitable silent-tool-registration vector"; the await closes the timing window but doesn't help if tools already landed, so we also drop them with `removeMcpToolsByServer()` after the disconnect resolves. No-op when discover hadn't reached registration yet. - McpClient.disconnect() now writes DISCONNECTED to the global registry directly. Previously, `isDisconnecting = true` was set BEFORE the internal `updateStatus(DISCONNECTED)` call, and `updateStatus`'s guard (designed to suppress LATE writes from a stale `connect()` catch) silently swallowed the write. The global stayed CONNECTED forever for timeout-disconnected servers, so `Config.getFailedMcpServerNames()` (which filters `status !== CONNECTED`) omitted them from the non-interactive failure banner and the Footer's MCP health pill kept counting them as healthy. This invalidated the round-5 `getMCPServerStatus === CONNECTED` gate, which would always pass the "ready" check for timed-out servers. The guard stays in place for its original purpose; the legitimate disconnect→DISCONNECTED notification now bypasses it by writing the registry directly. Also adds the `config_initialize_start` / `_end` profiler checkpoints to `Session.ensureConfigInitialized()` so stream-json startup profiles include the same derived `config_initialize_dur` phase as the non-stream-json branch in gemini.tsx (round 6 [Suggestion]). Tests cover (a) the disconnect-and-cleanup path on timeout and (b) the intentional-disconnect global registry propagation regression.

Mirrors the non-interactive stderr warning, adjusted to debugLogger so it doesn't collide with Ink's rendered output. - acpAgent per-session: `QwenAgent.initializeConfig()` now emits the same `Warning: MCP server(s) failed to start` stderr line as the top-level `runAcpAgent` path. Previously per-session ACP configs with failed MCP servers silently fell back to built-in tools. - mcp-client-manager timeout handler: after disconnecting an intentionally timed-out server, also drop it from `this.clients` and stop any pending health-check timer. Without this the discovery `finally` block would arm a health-check that detected DISCONNECTED status and called `reconnectServer()` → `discoverMcpToolsForServer()` directly — bypassing `runWithDiscoveryTimeout` entirely and silently resurrecting the slow server. `startHealthCheck` also early-returns for unknown servers so the trailing finally-block call is a no-op. - startupEventSink: silent `catch {}` now logs via `debugLogger.error` so a corrupted sink doesn't silently drop every subsequent event. Quiet by default; visible under `QWEN_CODE_DEBUG=1`. Tests: - mcp-client-manager.test.ts: regression for the timeout → no-reconnect invariant (clients map purged + health-check timer absent). - acpAgent.test.ts: per-session newSession surfaces failures to stderr, and stays safe when Config lacks `getFailedMcpServerNames`. Declines (with reasoning in PR reply): - [Critical] AppContainer batch-flush useEffect untested → re-flag of the round-5 deferral that wenshao acknowledged at the time. Lower- layer invariants (this PR's mcp-client-manager + mcp-client tests) pin the dependent contracts. The component-test harness for timers + event emitters in this file is non-trivial and out of scope; tracked for a follow-up.

qqqys	15e6222546	fix(dashscope): use URL hostname check instead of regex to avoid ReDoS (#4112) ... CodeQL flagged a polynomial regular-expression alert on the unanchored /([\w-]+\.)?dashscope(-intl)?\.aliyuncs\.com/i pattern introduced in #3991 — repeated '-' in the baseUrl could trigger catastrophic backtracking. The unanchored regex was also too permissive: it would incidentally match the dashscope domain appearing anywhere in a URL path, not just in the hostname. Parse the baseUrl with the URL constructor and compare hostname suffixes instead. This eliminates the ReDoS surface entirely and is strictly tighter — only real dashscope[-intl].aliyuncs.com hostnames (and their subdomains) match.

Shaojin Wen	870bdf2a9d	feat(cli,sdk): qwen serve daemon (Stage 1) (#3889) ... * feat(cli): scaffold `qwen serve` HTTP daemon (Stage 1, #3803) Adds a `serve` subcommand that boots an Express 5 listener with bearer auth, host allowlist, and CORS modeled on `vscode-ide-companion/src/ ide-server.ts`. Ships only `/health` and `/capabilities` to begin with; session/prompt/event routes will land in follow-up PRs once the per- session ACP child-process bridge in `httpAcpBridge.ts` is wired. Defaults to 127.0.0.1 with auth disabled so local development needs no configuration. Binding beyond loopback (e.g. `--hostname 0.0.0.0`) refuses to start without a token (`--token` or `QWEN_SERVER_TOKEN`). Capabilities envelope versioned at v=1 with a `features` array — clients should gate UI off `features`, never off `mode`, so subsequent PRs can add capability tags without breaking older clients. Per design issue's Stage 1 scope (~700-1000 LOC). Adds ~430 LOC of implementation + tests in this scaffold; the remaining budget belongs to the route wiring + bridge implementation in follow-ups. * feat(cli): wire HttpAcpBridge + POST /session for `qwen serve` (#3803) Stage 1 follow-up to the scaffold. Implements the bridge between the HTTP daemon and the existing ACP child agent, plus the first session endpoint. `HttpAcpBridge.spawnOrAttach`: - Spawns `node $cliEntry --acp` per workspace via an injectable `ChannelFactory` (default uses `process.argv[1]`; tests use an in-memory `TransformStream` pair so they don't fork real processes). - Drives the ACP `initialize` + `newSession` handshake via the SDK's `ClientSideConnection`, with a 10s timeout that kills the channel. - Under `sessionScope: 'single'` (default), reuses the live session when the same canonical workspace cwd is requested again — backs the `attached: true` flag. - The `Client` impl on the bridge side proxies file reads/writes to local fs (daemon and agent share the host) and buffers `sessionUpdate` notifications for the SSE wiring in the next PR. `requestPermission` returns `cancelled` until the `/permission/:requestId` route lands. `POST /session`: - 400 on missing or relative `cwd`. - 200 with `{sessionId, workspaceCwd, attached}` on success. - 500 on bridge failure (the failing channel is killed, not leaked). `runQwenServe` constructs the bridge and ties `bridge.shutdown()` into the listener-close path so SIGINT/SIGTERM drain children before the socket closes. Tests (14 new, 0 regressions in the 4967-test baseline): - 9 bridge cases over an in-memory channel — fresh spawn, single-scope reuse, cross-workspace isolation, thread-scope independence, path canonicalization, relative-path rejection, init failure cleanup, init timeout, multi-channel shutdown. - 4 route cases for /session (missing/relative/200/500). - 1 lifecycle case asserting `runQwenServe.close()` calls `bridge.shutdown()` before closing the listener. Verified end-to-end: `qwen serve` boots, `POST /session` spawns a real `qwen --acp` child and returns the SDK-assigned `sessionId`, repeat calls under the same cwd return `attached: true`, `SIGTERM` reaps the child along with the listener. * feat(cli): wire POST /session/:id/prompt + /cancel for `qwen serve` (#3803) Stage 1 follow-up after the bridge scaffold. Adds the two routes a client needs to actually run a turn against the daemon. Bridge: - `sendPrompt(sessionId, req)` looks up the session, FIFO-queues the call against the per-session prompt queue, and forwards through the SDK `ClientSideConnection.prompt`. Concurrent calls observe ACP's "one active prompt per session" invariant — second waits for first. - A failed prompt does NOT poison the queue; the tail catches and keeps draining so the next caller still runs (the original caller still sees its own rejection). - `cancelSession(sessionId, req?)` bypasses the queue and forwards the ACP notification immediately. ACP semantics: the agent winds down the *currently active* prompt; queued work is unaffected. - Both methods throw `SessionNotFoundError` (a typed Error subclass) when the id is unknown so route handlers can map cleanly to 404 without brittle message matching. - Both methods overwrite the `sessionId` field in the request body with the routing id — a stale or spoofed body would otherwise be dispatched to the wrong agent process. Routes: - `POST /session/:id/prompt` → 200 with PromptResponse, 400 on missing/non-array prompt, 404 on unknown session, 500 on agent error. - `POST /session/:id/cancel` → 204 always (cancel is a notification), 404 on unknown session. Tests (14 new — 7 bridge + 7 route, 0 regressions in the 4981 baseline): - sendPrompt: success forwards & returns response · routing-id overrides body sessionId · concurrent prompts FIFO-serialize (verified via per-prompt start/end ordering with a release latch) · failed prompt doesn't block subsequent prompts · 404 for unknown id. - cancelSession: forwards with routing id · 404 for unknown id. - Routes: 200/400/404/500 paths for prompt; 204 with body or empty + 404 for cancel. Verified end-to-end against a real `qwen --acp` child: - POST /session/:id/prompt with `[{type:'text',text:'hi'}]` → 200 `{"stopReason":"end_turn"}` in ~3.4s. - POST /session/:id/cancel → 204. - POST /session/does-not-exist/prompt → 404 with the unknown id surfaced in the body. * feat(cli): wire SSE streaming for `qwen serve` events (#3803) Stage 1 follow-up that turns prompt into a real streaming experience. Replaces the in-memory `notifications: SessionNotification[]` buffer on each session with a per-session EventBus and exposes it through `GET /session/:id/events` as an `text/event-stream` SSE feed. EventBus (`packages/cli/src/serve/eventBus.ts`): - Monotonic per-session ids (`v: 1` schema). Each `publish` chains an id, returning the materialized BridgeEvent. - Bounded ring (default 1000) backs `Last-Event-ID` reconnect — a consumer that drops can resume from `lastEventId` and replay any still-buffered events before live events flow. - Per-subscriber bounded queue (default 256). When a slow consumer overruns its queue, the bus appends a synthetic `client_evicted` terminal frame and closes that subscription so it can't hold the daemon hostage. Other subscribers are unaffected. - `subscribe()` returns an AsyncIterable — registration is synchronous so events `publish`ed immediately after the subscribe land in the queue (a generator-style implementation deferred registration to first `next()` and raced with publishes). - AbortSignal-aware: aborting the signal closes the iterator promptly. Bridge (`httpAcpBridge.ts`): - `BridgeClient.sessionUpdate` now publishes onto the session's EventBus instead of pushing to a plain array — every ACP notification the agent emits becomes a stream event automatically. - New `subscribeEvents(sessionId, opts?)` returns the bus's AsyncIterable; throws `SessionNotFoundError` for unknown ids. - Shutdown closes every live event bus before killing channels so pending consumers unwind cleanly. Route (`server.ts`): - `GET /session/:id/events` sets the SSE content type, advertises a 3s reconnect hint, and writes a 15s heartbeat comment frame to keep proxy/NAT connections alive. - Forwards the `Last-Event-ID` header to the bus. - `req.on('close')` triggers an AbortController that propagates into the bridge subscription so disconnects don't leak subscribers. - 404 when the bridge can't find the session. Capabilities envelope: `STAGE1_FEATURES` now advertises `session_create`, `session_prompt`, `session_cancel`, `session_events` in addition to `health`/`capabilities` so clients can light up UI for the routes that have actually shipped. Tests (16 new, 0 regressions in the 4995 baseline): - 9 EventBus unit cases — id sequencing, live delivery, replay, replay+live splice, fan-out to N subscribers, eviction on overflow, abort-signal unsubscribe, bus.close() drains subscribers, ring-size eviction. - 4 bridge subscribe cases — 404, sessionUpdate→event publishing via real ACP fake-agent, shutdown closes live subscriptions. - 4 SSE route cases against a live HTTP listener — frame format, Last-Event-ID forwarding, 404, abort propagation on disconnect. Verified end-to-end against a real `qwen --acp` child: - Subscribed to `/session/$SID/events`, fired `POST /session/$SID/prompt` with text content. Captured 13 distinct `event: session_update` SSE frames in real time during the model's response — `available_ commands_update` metadata, 9 `agent_thought_chunk` frames carrying the model's chain-of-thought, 3 `agent_message_chunk` frames with the actual reply, and a final usage frame with token totals. - Frames carry monotonic ids 1..13, the daemon-side counter, and are valid SSE per the EventSource spec. * feat(cli): wire POST /permission/:requestId for `qwen serve` (#3803) Stage 1 follow-up that turns `BridgeClient.requestPermission` from a hardcoded `cancelled` placeholder into a real first-responder vote loop, and ships the HTTP route any attached client uses to cast the deciding vote. Bridge: - `requestPermission` generates a UUID requestId, registers a pending entry on a daemon-wide map (and the owning session's `pendingPermissionIds` set), publishes a `permission_request` event onto the session's EventBus (so SSE subscribers see it), and awaits the resolution. - New `respondToPermission(requestId, response)` resolves the pending promise with the supplied outcome. First call wins — subsequent calls return false. On success the bridge publishes a `permission_resolved` event so other attached clients can update their UI when the race is decided. - `cancelSession` and `shutdown` both resolve every still-pending permission for the affected session(s) as `{ outcome: { outcome: 'cancelled' } }` per the ACP spec requirement that a cancelled prompt MUST resolve outstanding requestPermission calls with cancelled. - New `pendingPermissionCount` getter exposes inflight count for inspection / tests. Route (`server.ts`): - `POST /permission/:requestId` validates the body's `outcome` is either `{ outcome: 'cancelled' }` or `{ outcome: 'selected', optionId: string }`, then forwards to `bridge.respondToPermission`. - 200 on accepted vote, 404 when the requestId is unknown or already resolved (Stage 1 doesn't differentiate), 400 on a malformed outcome. Capabilities envelope: STAGE1_FEATURES gains `permission_vote`. Tests (14 new — 9 bridge + 5 route, 0 regressions in the 5011 baseline): - Bridge: publishes permission_request with a generated requestId and waits; respondToPermission first-responder wins; publishes permission_resolved on vote; respondToPermission false for unknown requestId; cancelSession resolves outstanding as cancelled; shutdown resolves outstanding as cancelled. - Route: 200 on selected outcome; 200 on cancelled outcome; 404 on unknown requestId; 400 on malformed outcome; 400 on missing outcome. Verified end-to-end against a real `qwen --acp` child: - Subscribed to /session/$SID/events, sent a prompt asking the agent to write a file at /tmp/qwen-serve-permission-e2e-test.txt. - The agent triggered a permission_request via the bus, surfacing the three options Qwen Code presents (Allow Always / Allow / Reject) with their option ids. - POSTed `{outcome:{outcome:"selected",optionId:"proceed_once"}}` to /permission/$requestId — got HTTP 200. - Bus published the matching permission_resolved event. - Agent proceeded with the writeTextFile tool call; file was actually created on disk with the expected content. * feat(sdk): add DaemonClient for the qwen serve HTTP API (#3803) Stage 1 follow-up that proves the cross-mode protocol-isomorphism design assumption: an SDK client can drive the daemon's HTTP routes end-to-end without going through ProcessTransport's stdio + stream-json path. DaemonClient is a sibling of ProcessTransport, not a replacement. The two speak different protocols (ACP NDJSON over HTTP vs stream-json over stdio). Existing `query()` users keep getting subprocess-mode unchanged; applications that want daemon-mode (cross-client attach, shared MCP pool, network reachability, first-responder permissions) opt in by constructing a DaemonClient against a running `qwen serve`. API surface (`packages/sdk-typescript/src/daemon/`): - `new DaemonClient({ baseUrl, token?, fetch? })`. The `fetch` override is for tests; defaults to `globalThis.fetch`. Trailing slashes on `baseUrl` are stripped. - `health()`, `capabilities()` — discovery. - `createOrAttachSession({ workspaceCwd, modelServiceId? })` — `attached: true` on the response indicates a session was reused under sessionScope:single. - `prompt(sessionId, { prompt: ContentBlock[] })` — returns PromptResult with stopReason. - `cancel(sessionId)` — tolerates 204; throws on 404. - `subscribeEvents(sessionId, { lastEventId?, signal? })` — async iterator over parsed SSE frames; AbortSignal-aware. Native Node AbortController only — jsdom polyfills are incompatible with undici. - `respondToPermission(requestId, response)` — first-responder vote; returns true on 200, false on 404 (lost the race or unknown id), throws on 400/500. `DaemonHttpError` is thrown for any non-2xx (besides the 404 "already-resolved" case on permission votes); carries `status` and `body` so callers can branch on standard daemon HTTP semantics. `parseSseStream(body)` is the underlying SSE parser; exported separately so applications can consume daemon SSE outside the DaemonClient surface. Handles split-chunk frames, comment/retry directives, malformed JSON (skip), trailing frame without final newline. Wire types live SDK-side (no SDK→CLI dep); the capabilities envelope's `v` field signals breaking changes. Tests (26 new, 0 regressions in the 201 baseline): - 7 SSE parser cases — single frame, multiple frames, comments, chunked-split frame, malformed JSON skip, trailing frame on close, empty stream. - 19 DaemonClient cases — health success/error, capabilities, bearer auth presence/absence, createOrAttachSession success/400, prompt body shape + sessionId url-encoding, cancel 204/404, permission 200/400/404, subscribeEvents header forwarding + 404, baseUrl normalization. Verified end-to-end against a real `qwen serve` daemon driving a real `qwen --acp` child: - `client.capabilities()` returned `{v:1, mode:"http-bridge", features: [...7 tags]}`. - First `createOrAttachSession` returned `attached:false`; second returned `attached:true` with the same sessionId. - `client.prompt(...)` with text content yielded `{stopReason: "end_turn"}` while the parallel `subscribeEvents` iterator streamed 10 distinct frames during the same turn. - AbortController on the events iterator cleanly severed the SSE connection. * feat(cli,sdk): list workspace sessions + set session model (#3803) Closes the §04 Stage-1 routes table for `qwen serve` with the two remaining endpoints, plus matching SDK methods. `GET /workspace/:id/sessions` - `:id` is the URL-encoded canonical absolute workspace path (Express decodes path params automatically; clients pass `encodeURIComponent(cwd)`). - Returns `{ sessions: [{ sessionId, workspaceCwd }, ...] }` for live sessions whose canonical workspace matches. - Empty array (not 404) when the workspace is idle so picker UIs don't have to special-case "no sessions yet". - 400 when the decoded path isn't absolute. `POST /session/:id/model` - Body: `{ modelId: string, ... }`. The route's `:id` overrides any spoofed sessionId in the body. - Forwards to ACP's `unstable_setSessionModel` and publishes a `model_switched` event onto the session bus so cross-client UIs update. - 200 with the agent's response on success, 400 on missing/empty modelId, 404 on unknown session. - The SDK method is currently unstable; documented in the bridge comment in case the spec renames the method when it stabilizes. Bridge: - New `listWorkspaceSessions(workspaceCwd)` iterates `byId.values()` and filters by canonical workspace path; works for both `single` and `thread` session scopes. - New `setSessionModel(sessionId, req)` forwards through `connection.unstable_setSessionModel`, normalizes sessionId, publishes `model_switched`, throws SessionNotFoundError on unknown ids. `STAGE1_FEATURES` capabilities envelope grows to 9 tags, adding `session_list` and `session_set_model`. SDK (`DaemonClient`): - `listWorkspaceSessions(workspaceCwd)` URL-encodes the cwd and returns the parsed `sessions` array directly. - `setSessionModel(sessionId, modelId)` POSTs the body and returns the agent response (currently opaque per ACP unstable spec). - Wire types `DaemonSessionSummary` and `SetModelResult` exported from the SDK barrel. Tangential cleanup: `sendBridgeError` now extracts a useful message from non-Error values via a small `errorMessage` helper. JSON-RPC errors from the agent (`{code, message, data}`) used to surface as `"[object Object]"` in the 500 response body; they now show the inner `message` field. Caught while running the model-set e2e. Tests (17 new — 9 bridge + 7 route + 4 SDK, 0 regressions in the 5022 + 227 baselines): - Bridge listWorkspaceSessions: matching cwd returns the live sessions; canonicalizes the lookup; empty for relative paths. - Bridge setSessionModel: forwards modelId + overrides body sessionId; publishes model_switched event; 404 unknown session. - Route /workspace/:id/sessions: returns the bridge list; empty for idle workspace; 400 for relative path. - Route /session/:id/model: 200 success; 400 missing modelId; 400 empty modelId; 404 unknown session. - SDK listWorkspaceSessions: URL-encodes the cwd; throws on 400. - SDK setSessionModel: posts body; throws on 404. Verified end-to-end against a real `qwen serve`: - SDK reports 9 capability features, list returns the existing session, attached:true on repeat create, and `setSessionModel` rejects with HTTP 500 when the modelId isn't registered (with the daemon now surfacing "Internal error" instead of "[object Object]"). - 404 path through SDK on unknown sessionId works. * fix(cli,sdk): audit round 1 follow-ups for `qwen serve` (#3803) Self-review pass on PR #3889. Two real correctness bugs and an ergonomics gap, plus the test-coverage holes the audit surfaced. The loudest finding ("host allowlist no-op when bind=localhost") was a false positive — the conditional was misread; existing tests already prove the validator is active on `localhost` binds. Real fixes: - Bearer-auth timing-attack: `parts[1] !== token` short-circuits per byte, leaking which prefix is correct via response latency. Replace with SHA-256 of both sides + `crypto.timingSafeEqual` so comparison is constant-time regardless of token length. - Concurrent `spawnOrAttach` race in single-scope: two parallel callers for the same workspace both passed the `byWorkspace.get` check, both spawned, and one entry ended up orphaned in `byId` while the other won `byWorkspace`. Violates the "at most one session per workspace" invariant. Coalesce via an `inFlightSpawns` map: parallel callers attach to the in-flight promise and report `attached: true`. The slot is cleared on both success and rejection so a failed spawn doesn't poison the workspace forever. New test asserts ONE channel spawns under parallel calls and that retry works after rejection. - `Number.parseInt('1.5e10z', 10)` returns 1, so a malformed `Last-Event-ID` header silently passes through. Tighten `parseLastEventId` to `^\d+$` so anything not a pure decimal integer is dropped. New test exercises 'abc', '-1', '1.5e10z'. Ergonomics: - `LOOPBACK_BINDS` and `LOOPBACK_HOST_BINDS` now include `::1` and `[::1]`. IPv6 loopback users no longer have to set a token. Host-allowlist allows `[::1]:port` Host headers. Documentation: - `BridgeClient` doc-comment now states the Stage 1 trust model explicitly: agent runs as the same UID, the file-proxy methods are NOT a workspace-cwd sandbox, restricting them would be theatre. The audit flagged this as a "design gap" but the daemon-and-agent-on-same-host posture makes a sandbox here redundant — Stage 4+ remote-sandbox swaps the Client for a sandbox-aware variant. SDK fix: - `DaemonClient.failOnError` previously called `res.json()`, which consumes the body even on parse-failure; the subsequent `res.text()` returned empty. New impl reads once as text and attempts JSON-parse; raw text is the fallback. New test asserts a `text/plain` 502 surfaces the body verbatim. Test gap fills (audit-flagged): - Bridge: in-memory file-proxy tests for `BridgeClient.{read,write} TextFile` including line/limit slicing. - SSE route: `stream_error` synthetic frame on iterator throw mid-stream; numeric Last-Event-ID forwarded; malformed Last-Event-ID dropped. - DaemonClient: text/plain error body coerced to `body` field; `respondToPermission` 5xx throws; `subscribeEvents` null-body throws; `cancel`/`respondToPermission` URL-encode session/request ids that contain slashes. Verified end-to-end with a token-required daemon: right token → 200, wrong/missing/malformed → 401. All paths return uniform 401 messages so a side-channel can't distinguish between "no header", "bad scheme", and "wrong token". Test counts: cli serve **89** (was 81, +8), sdk daemon **35** (was 30, +5). Full suites still green. * fix(cli): audit round 2 follow-ups for `qwen serve` (#3803) Second self-review pass on PR #3889. Three real bugs (one correctness, one resource-cleanup, one cosmetic) plus consolidation of the loopback bindings into a single source of truth. Real fixes: - Shutdown could hang forever on a long-lived SSE consumer: `server.close` waits for every in-flight connection to drain, and a paused EventSource client never disconnects. Added a `SHUTDOWN_FORCE_CLOSE_MS` (5s) timer that calls `server.closeAllConnections()` to force-destroy stuck sockets, then resolves so `process.exit(0)` can run. New test asserts close completes well under 5.5s even when an SSE GET is in flight. - Signal-handler race during shutdown: round 1 detached the SIGINT/SIGTERM listeners *up front* in `handle.close()`. If a second SIGTERM arrived during the drain, no handler existed and Node's default termination ran, orphaning agent children. Switch to detaching at the *end* of the close path (in `finish()`): during the drain window the handler is still attached and the `if (shuttingDown) return` guard makes a second signal a no-op; after drain completes we can safely remove the listeners (this also fixes a test-suite MaxListenersExceededWarning that fired once we ran the runQwenServe tests >10 times in a single process). - SSE response had no `error` listener. When the underlying TCP socket died (RST, kill -9 on the client), the next `res.write` threw EPIPE and Express forwarded it to the default error handler, logging noisily. Added `res.on('error', cleanup)` so the failure is absorbed and triggers the same teardown path the `req.on('close')` handler uses. Validation: - `createHttpAcpBridge` now throws on invalid `sessionScope` (anything other than `'single'` or `'thread'`) and on `initializeTimeoutMs <= 0`. Misconfigured callers used to silently degrade to thread behavior; now they fail loudly. Cleanup: - The `LOOPBACK_BINDS` set was duplicated between `auth.ts` and `runQwenServe.ts` (round 1 missed this). Extracted into `packages/cli/src/serve/loopbackBinds.ts` with a single `isLoopbackBind(hostname)` helper. Both files now import; drift is impossible. - `res.flushHeaders?.()` lost the optional chaining. The method is on `http.ServerResponse` since Node 1.6; our `engines` floor is 20. Tests added: - bridge: `sessionScope` validation, `initializeTimeoutMs` validation. - server: shutdown force-close timeout, SIGINT/SIGTERM listener detach-after-drain. False positives from the round 2 audit (verified and dismissed): - "EventBus nextId overflow at 2^53" — theoretical only (would require ~9 quadrillion publishes per session). No code change. - "Subscribe-during-close race" — JS is single-threaded; the close() flag is set synchronously before the loop touches state. - "Queued prompts on shutdown" — by design; documented via the promptQueue tail comment. - "10MB body parser limit" — design choice for Stage 1's in-memory buffering model; revisit if ACP streaming lands in Stage 2. - "Unbounded body read in DaemonClient.failOnError" — daemon is local in Stage 1; the threat surface for adversarial-large error bodies is the same as the daemon's other unbounded buffers. Test counts: cli serve **93** (was 89, +4), full cli **5047** (no regressions), sdk **236** (no regressions). * docs(cli): audit rounds 3 + 4 follow-ups for `qwen serve` (#3803) Two more self-review passes on PR #3889. No correctness bugs surfaced this time — round 3 found a HIGH-severity Windows-path claim that turned out to be a false positive (`path.win32.isAbsolute('/foo/bar')` returns true; verified against Node 20). Round 4 confirmed every prior decision and surfaced one latent-but-not-currently-triggered concurrency note. Changes are pure documentation + a tiny optional-chain cleanup: - Drop `?.` on `server.closeAllConnections()` in runQwenServe.ts — the method exists since Node 18.2 and our `engines` floor is 20. The optional chain dated from before round 2's force-close timer landed; clean it up. - Help text for `qwen serve --port` now documents that port 0 means "OS-assigned ephemeral port" (which the implementation has always supported but never advertised). - `defaultSpawnChannelFactory` gains a comment near the spawn site documenting the FD-budget implication (~3 FDs per session, bump `ulimit -n` for many concurrent sessions) and the `stdio: ['pipe', 'pipe', 'inherit']` choice (child stderr lands in the daemon's stderr, interleaved across sessions). Both are Stage-1-accepted; Stage 2/4+ revisit each. - Comment on the bridge's `byWorkspace`/`byId` Maps documenting the known gap that a child crashing between requests leaves a garbage SessionEntry until daemon shutdown — surfaced as a per-prompt failure when the dead session is touched, not a hang. Stage 2's in-process bridge eliminates the spawned-child failure mode entirely so this gap goes away naturally. - `EventBus.subscribe` doc-comment now states explicitly that the returned iterator is NOT safe to drive from concurrent `.next()` callers — the underlying queue isn't atomic. Daemon usage is the sequential `for await ... of` inside the SSE route, so this is safe in production. Documented so a future fan-out consumer doesn't accidentally rely on undefined behavior. False positives verified and dismissed (round 3 + 4 combined): - `path.isAbsolute('/foo/bar')` Windows breakage — `path.win32. isAbsolute('/foo/bar')` is true; verified empirically. - "Windows drive divergence" causing duplicate sessions — different drives are different on-disk paths; sessions intentionally differ. - "parseSseStream early-break leaks reader" — `for await ... break` triggers `iterator.return()` which runs the generator's `finally` that calls `releaseLock`. Standard JS semantics. - "Promise executor sync-throw fragility in requestPermission" — sync throws inside `new Promise(executor)` reject the outer promise; functionally correct, just stylistic. - "Force-close timeout test elapsed assertion flakiness" — assertion is `< 5500ms` but the natural happy-path is sub-100ms. Generous headroom; not flake-prone in practice. - "fetch reference stale after polyfill" — `globalThis.fetch.bind` captures at construction; tests inject `opts.fetch` instead of polyfilling, which is the correct pattern. Test counts unchanged (cli serve **93**, sdk **236**); typecheck + lint clean. STAGE1_FEATURES still matches every implemented route 1:1, fakeBridge in tests implements every HttpAcpBridge method. * fix(cli): PR #3889 review round 1 — critical correctness (#3803) Addresses the four critical findings from the PR #3889 reviewer pass: 1. ACP `ReadTextFileRequest.line` is 1-based per spec, but the bridge's `BridgeClient.readTextFile` was treating it as a 0-based slice index. A client asking for `{line:1, limit:2}` ("first two lines") was getting lines 2-3 — a sign-off-by-one bug that breaks every editor / SDK client following the ACP schema. Convert to 0-based via `Math.max(0, line - 1)`. The existing slice test was asserting the wrong behavior; updated to expect the spec-correct result and added a second `line:3, limit:2` case to lock in the offset. 2. `modelServiceId` was accepted by the SDK + server `POST /session` path, forwarded into `bridge.spawnOrAttach`, and then silently dropped: `doSpawn` never wired it into the agent. Callers requesting a specific model got the agent's default and no indication anything was wrong. Now `doSpawn` issues `unstable_setSessionModel` immediately after `newSession`. If the agent rejects the model id, the half-initialized session is torn down and the spawn rejects so the caller can retry cleanly instead of inheriting silent drift. Three new bridge tests: happy path, omit-when-undefined, agent-rejection cleanup. 3. The CORS middleware used `cors({ origin: (o, cb) => cb(new CORSError(...), false) })` for browser-Origin requests. `cors` flows the Error into Express's error chain; without an explicit error handler that produces a 500 + HTML body, which is misleading for what is really a deterministic 403 denial. Replace with a tiny `RequestHandler` that checks `req.headers.origin` directly and returns `403 { error: 'Request denied by CORS policy' }` JSON. Drops the `cors` and `@types/cors` dependencies — there's no other consumer in the cli package. 4. The SSE `stream_error` synthetic frame hard-coded `id: 0`, which would regress the client's `Last-Event-ID` tracker and trigger duplicate replays on reconnect. The frame is terminal and daemon-emitted — it has no place in the per-session monotonic sequence. Refactor `formatSseFrame` to omit the `id:` line when the input event has no id field, and emit `stream_error` without one. Test updated to assert `frames[1].id === undefined` while the preceding `session_update` still carries its monotonic id. Tangential cleanup: `errorMessage` now formats the SSE error body (was `err.message` only — would have shown `[object Object]` for JSON-RPC errors mid-stream, mirroring the round-1 SDK fix). Test counts: cli serve **96** (was 93, +3 modelServiceId cases); existing readTextFile slice test rewritten in place. Full typecheck + lint + suite green. * fix(cli,sdk): PR #3889 review round 2 — SSE robustness + EventBus polish (#3803) Second batch of reviewer-flagged fixes for PR #3889. Addresses 7 robustness issues across the daemon's SSE pipeline + the bus + the SDK's stream parser. Daemon SSE (`server.ts`): - SSE writes now respect backpressure. `res.write` returns false when the kernel send buffer is full; the previous code ignored that and Node accumulated payloads in user-space memory unboundedly. A slow consumer on a chatty session could balloon daemon RSS. New `writeWithBackpressure` helper awaits `drain` (or `close`/`error`) before scheduling the next write — for both per-frame writes and heartbeats. - `parseLastEventId` rejects values > `Number.MAX_SAFE_INTEGER`. With the prior `^\d+$` regex a malicious 25-digit value would parse to a number that loses precision and confuses replay comparisons. EventBus (`eventBus.ts`): - `Last-Event-ID` replay events now `forcePush` past `maxQueued`. A client reconnecting with a 1000-event gap on a subscriber whose cap is 256 was silently losing entries 257-1000 — a sign-off-by- nothing breakage of the resume contract. Live publishes still go through the normal cap (slow live consumer must be evictable); historical replay is bypassed. - `onAbort` now disposes the subscription immediately instead of only closing the queue. An aborted-but-never-iterated subscriber used to linger in `bus.subs` until the consumer drove `next()` / `return()`. New tests cover both abort-after-subscribe and already-aborted-at-subscribe paths. - `BoundedAsyncQueue.next` now checks `buf.length > 0` before shifting instead of `buf.shift() !== undefined`. The bus never pushes `undefined` today but the queue is generic — the prior pattern would mis-handle a queue whose element type legitimately includes undefined. SDK SSE parser (`sse.ts`): - Now flushes the TextDecoder on stream close. Without the final `decoder.decode()`, an incomplete multi-byte UTF-8 sequence at the tail of the last chunk was silently dropped — corrupting any frame whose JSON ended mid-character. New test feeds a stream split mid-byte through "中" (3-byte UTF-8) and asserts the character round-trips. - Frame separators now accept both `\n\n` and `\r\n\r\n`. SSE spec allows CRLF, and intermediaries (corporate proxies, some Node http servers) sometimes normalize. Frame field splitter also accepts `\r?\n`. Two new tests cover pure CRLF + mixed-LF/CRLF. Test counts: cli serve **99** (was 96, +3 EventBus); sdk daemon-sse **10** (was 7, +3). Full typecheck + lint + suite green. * docs(cli,sdk): PR #3889 review round 3 — minor + docs (#3803) Last batch from the PR #3889 reviewer pass: mostly docs + a ReDoS-tooling-silencing rewrite + a yargs-key cleanup. - `commands/serve.ts` ServeArgs interface dropped the camelCase `httpBridge` mirror; the handler now reads `argv['http-bridge']` matching the declared option name. The dual surface relied on yargs's camelCase expansion behavior — fragile if yargs config ever changes. - `DaemonClient` constructor's `baseUrl.replace(/\/+$/, '')` (which is end-anchored and linear, but CodeQL's polynomial-regex detector flags any `\/+$` pattern on attacker-controlled input) swapped for a hand-rolled `stripTrailingSlashes` loop. Same behavior, no rule trigger. - `defaultSpawnChannelFactory`'s `cwd: workspaceCwd` flow into `spawn` is the second CodeQL finding ("uncontrolled data used in path expression"). It IS user-controlled, by design — that's the Stage 1 trust model. Added a `// lgtm[js/shell-command- constructed-from-input]` suppression with a comment explaining the model and pointing at issue #3803 §11 for the Stage 4+ remote- sandbox replacement. - Stale doc comment on `createServeApp` that still listed only `/health`, `/capabilities`, `POST /session` as shipped — now enumerates all 9 routes that match §04 of the design. - Stale doc comment on `HttpAcpBridge` saying "Stage 1 buffers them in-memory; SSE wiring lands in the next PR" — SSE wiring landed in commit 41aa95094. Replaced with a description of the actual flow through EventBus + SSE. No behavior change; tests + lint + typecheck still green. cli serve still **99**, sdk **38** (was 30 before this batch — daemon-sse +3, DaemonClient +5 from rounds 1+2). Full e2e against built daemon re-verified: CORS denial returns 403 JSON (was 500 HTML), bad `modelServiceId` now causes spawn to fail with HTTP 500 (was: silent default-model substitution), `POST /session` without modelServiceId unaffected. * fix(cli,sdk): self-audit round 5+ — close orphaned EventBus + DaemonEvent.id optional (#3803) Two more fixes from a final post-review-comment audit pass on PR #3889. Both are subtle correctness gaps that fell out of the round-1 critical fixes (modelServiceId apply + SSE id-less stream_error). - In `httpAcpBridge.ts:doSpawn`, when `unstable_setSessionModel` rejects after `newSession` succeeded, we tear down the entry from `byWorkspace` + `byId` (round 1 fix) but did NOT close the EventBus we'd just constructed for that entry. The agent could have published a session_update notification during init that queued in the (now unreachable) bus's ring buffer; without an explicit close the bus + buffer linger until the next GC cycle. Bounded leak (1 bus per failed spawn × 1000-event ring) but cleaner to close it. New regression test exercises the retry path after a model-rejection failure to lock in that we don't reuse the orphan and that subscribers on the fresh session see an empty iterator on immediate abort. - SDK `DaemonEvent.id` is now `id?: number` instead of `id: number`. The round-1 SSE fix made the daemon emit `stream_error` frames *without* an `id:` line so they don't pollute the per-session monotonic sequence. The SDK parser correctly returns `undefined` for the missing field, but the type still advertised `id: number` — TypeScript consumers persisting `lastSeenId = event.id` would accidentally store `undefined`. Made the field optional and added a doc comment instructing consumers to skip frames without an id. Plus one more false-positive verified and dismissed: - "writeWithBackpressure Promise double-settle race": the auditor flagged that `res.write(chunk, callback)` could fire its callback after the synchronous `ok=true` resolve. Verified harmless — Promise double-settle is a no-op, the callback only rejects on error (caught separately by `res.on('error', cleanup)`), and multiple parallel writes register independent listener sets that each remove their own pair after firing. Test counts: cli serve **100** (was 99, +1 retry-after-model-rejection regression). SDK unchanged at 239. Full typecheck + lint + suites green; flow re-verified end-to-end. * fix(cli,sdk): PR #3889 review round 4 — child-crash recovery + SSE/permission/SSE polish (#3803) Fourth and final batch of reviewer-flagged fixes for PR #3889. 14 inline threads addressed, plus 8 spam threads up for resolution. Critical correctness: - `eventBus.test.ts`'s ring-eviction test wrapped its assertion in a `void (async () => { … })()` IIFE that returned synchronously to vitest — the inner `expect` could fail without ever surfacing. Hoisted to a top-level `await` so the harness actually waits and a broken eviction would now fail loudly. - `runQwenServe.ts handle.close()` is now idempotent. Concurrent callers (test harness + signal handler firing simultaneously, explicit caller + finally-block fallback) used to each construct a new shutdown promise, arm a fresh force-close timer, and call `bridge.shutdown` redundantly. Cache a single `closePromise`; repeat calls return it. New test exercises 3 overlapping callers + a post-settle call → exactly one bridge.shutdown. - `POST /permission/:requestId` now rejects `outcome.selected` with an empty `optionId`. The string-typeof check passed `""` through; bridge would forward an opaque "unknown option" error from the agent. Tighten the validator + add a 400 test. - `denyBrowserOriginCors` now has explicit unit tests (3 cases: Origin-bearing GET → 403 JSON, no-Origin GET → 200, Origin-bearing POST → 403 + bridge untouched). The CSRF defense was previously implicit-only. Channel-exit recovery: - `AcpChannel` interface gains an `exited: Promise<void>` that resolves on either planned `kill()` or unexpected child crash. Bridge subscribes via `channel.exited.then(...)`: if the entry is still in `byId` when exit fires (i.e. unexpected crash), it cancels pending permissions, publishes a `session_died` event so SSE subscribers get notified, closes the bus, and removes the entry from `byWorkspace`/`byId`. Without this, a crashed child used to leave its `SessionEntry` stuck — under `sessionScope:'single'` (default) the whole workspace was unreachable until daemon restart. - `defaultSpawnChannelFactory` now wires `child.once('error', …)` in addition to `'exit'`. Without an `error` listener Node treats an async spawn failure (ENOMEM, EACCES, …) as an unhandled error and crashes the daemon. - Two new bridge tests: `crash()` simulates an unexpected exit → asserts `session_died` event + entry removed + retry spawns a fresh child; planned shutdown asserts the cleanup handler no-ops when the entry is already gone (no double-publish). SSE robustness: - SDK `parseSseStream` now calls `reader.cancel()` (not just `releaseLock`) in its `finally`. Early-break consumers were leaving the underlying HTTP body stream open; cancel propagates upstream so the connection drops promptly. New test asserts the underlying ReadableStream's `cancel()` runs. - SDK `parseSseStream` accepts `data:` (no space after colon) AND multiple `data:` lines per frame (joined by `\n` per spec). Two new tests cover both cases. - SDK `DaemonClient.subscribeEvents` now validates response Content-Type before delegating to the parser. A misconfigured proxy returning 200 + JSON was silently producing zero events; now throws `DaemonHttpError` with the actual mime type. - Daemon SSE route's initial `retry: 3000` write now `.catch(()=>{})`s. A socket that errors before the first write would have surfaced as an unhandled rejection. Documentation (deferred items now noted in code): - `EventBus.publish` ring shift is O(n) when full. Comment notes the deferral; circular-buffer refactor only if profiling flags it. - SSE heartbeat doesn't detect dead connections without TCP RST. Comment notes Stage 2 may add an explicit idle timeout. - `defaultSpawnChannelFactory` won't run a `.ts` entry directly — `npm run dev` users must build first. Comment in the spawn site. Test counts: cli serve **107** (was 100, +7), SDK daemon **42** (was 38, +4). Full typecheck + lint + suite green. * test(integration): qwen serve daemon — routes + streaming + recovery (#3803) Persists the e2e validation of every PR #3889 fix as vitest integration tests under `integration-tests/cli/`. Two files split by auth requirement: `qwen-serve-routes.test.ts` (18 cases, no LLM credential needed) - Bearer auth timing-safe compare: right token / wrong-same-length / wrong-shorter / missing / Basic-scheme. - CORS browser-Origin denial: GET-with-Origin → 403 JSON; no-Origin → 200. - Capabilities envelope: all 9 Stage 1 features advertised in order. - POST /session validation: relative cwd → 400; two parallel POSTs same workspace coalesce; bad modelServiceId tears down half-init. - POST /permission/:requestId validation: empty optionId → 400; missing optionId → 400; valid vote on unknown id → 404. - SDK SSE Content-Type guard: throws DaemonHttpError when upstream returns 200 + JSON. - Last-Event-ID strict parsing: malformed value accepted but ignored (`'1abc'` doesn't get parsed as 1). - Cancel idempotent + listWorkspaceSessions returns the live session. `qwen-serve-streaming.test.ts` (3 cases, gated by SKIP_LLM_TESTS) - Real `qwen --acp` child SIGKILL → daemon publishes `session_died`, removes the entry from `byWorkspace`/`byId`, next createOrAttachSession spawns fresh. Uses `pgrep -P` to locate the daemon's direct child by PID. - Two SSE subscribers + a tool requiring permission: both observe the same `permission_request` requestId; two concurrent POST votes resolve as exactly one 200 + one 404 (first-responder wins). - SSE reconnect with `Last-Event-ID: N` after consuming N frames yields events with `id > N` from the bus's replay ring. Both files spawn `node packages/cli/dist/index.js serve --port 0 --token …` per `beforeAll` and clean up in `afterAll`. Use the existing `@qwen-code/sdk` alias the integration-tests vitest config already wires to the built SDK bundle. Run with the existing `npm run test:integration:cli:sandbox:none` (or any of the integration-tests target). The streaming file is skip-able via `SKIP_LLM_TESTS=1` for environments without auth. Verified locally: 18/18 routes pass in ~6.8s; 3/3 streaming pass in ~23s against a real model. * fix(cli): PR #3889 review round 5 — claude-opus-4-7 audit (#3803) Seven new substantive findings from a `/qreview` pass on PR #3889. Six real bugs + one type-safety gap; all addressed. Critical correctness: - **EventBus replay overflow + eviction race**. Round 4's `forcePush` for `Last-Event-ID` replay bypassed the per-subscriber cap, but `BoundedAsyncQueue.push`'s cap check was `buf.length >= maxSize` — so the very next live publish saw the inflated buf, rejected, and triggered the `client_evicted` terminal frame. Concrete sequence the audit walked through: client reconnects after 300+ events, replay force-pushes 300 entries, next live event evicts them. Defeats the resume contract. Fix: track force-pushed items separately (`forcedInBuf` counter). `push()` cap is now on `(buf.length - forcedInBuf)`. `next()` decrements `forcedInBuf` as the consumer drains (force-pushed entries are FIFO at the front of `buf` since `forcePush` only runs at subscribe time, before any live `push`). Two new regression tests: (1) live publish after a >cap replay does NOT evict; (2) eviction triggers only after the LIVE backlog (excluding replay) hits the cap. Performance + UX: - **Eager express import on every `qwen` invocation**. The `serve` subcommand statically imported `../serve/index.js`, which transitively pulled express + body-parser + qs into cold-start path of every CLI invocation (interactive, mcp, channel, etc). ~50ms tax on the 99% of invocations that never run `serve`. Defer to dynamic `import()` inside the handler; types are still imported for the builder shape. - **Middleware order**: `express.json({limit:'10mb'})` ran BEFORE `bearerAuth`. Unauth POST got full JSON.parse before 401. Trivial DoS amp on non-loopback deployments. Reorder so auth + Host allowlist + CORS run first; body parser runs only for requests that pass the gate. - **`sendPrompt` no AbortSignal**. A stuck/dead child poisons the per-session FIFO; HTTP client disconnect didn't propagate so daemon CPU stayed tied up. `HttpAcpBridge.sendPrompt` now accepts `signal?: AbortSignal`. Route handler creates an AbortController and wires `req.on('close')` to abort it. On abort, bridge sends an ACP `cancel` notification; the agent winds down → prompt resolves with `stopReason: 'cancelled'` → next queued prompt can run. New test exercises real socket disconnect via `node:http` (jsdom AbortSignal isn't compatible with undici). Security: - **`--token` on argv leaks via `/proc/<pid>/cmdline`**. Default Linux permissions allow any local user to `ps auxww | grep 'qwen serve'` and read the bearer token. Daemon now warns to stderr when `--token` is used and recommends `QWEN_SERVER_TOKEN` (which uses `/proc/<pid>/environ`, owner-only). - **Token inherited by spawned `qwen --acp` child**. `env: process.env` in `defaultSpawnChannelFactory` passed `QWEN_SERVER_TOKEN` into the child. The agent runs user-supplied prompts with shell-tool access — leaving the token in env enables prompt-injection-into-self-call attacks. Strip `QWEN_SERVER_TOKEN` from the child's env before spawn. Robustness: - **`BridgeClient` publishes lacked try/catch on closed bus**. `BridgeClient.requestPermission` and `sessionUpdate` called `entry.events.publish(...)` directly. Shutdown closes the bus *before* killing the channel, so a late `sessionUpdate` from a not-yet-dead agent throws. For `requestPermission` the throw was particularly bad: `registerPending` had already mutated the daemon-wide map, so the throw left the registry inconsistent. Cleaner fix: make `EventBus.publish` a no-op on closed bus (returns undefined) instead of throwing. Removes the need for try/catch at every call site and keeps state consistent. Type safety: - **`STAGE1_FEATURES: readonly string[]`** widened the inferred tuple-of-literals back to `string[]`. A typo'd feature (`'sesion_set_model'`) compiled silent. Drop the annotation + add `as const`; export `Stage1Feature` literal-union for SDK-side `features.includes(...)` checks to narrow against. Test counts: cli serve **112** (was 105, +7); SDK unchanged at 243. Full typecheck + lint + suite green. * fix(cli): PR #3889 review round 6 — gpt-5.5 audit (#3803) Four new findings from a `/review` pass on PR #3889. Three real correctness bugs + one Stage 1 design-gap documentation. Critical: - **`[::1]` bind ENOTFOUND**. `LOOPBACK_BINDS` accepts `[::1]` for the auth gate, but `app.listen()` wants the unbracketed `::1`; `qwen serve --hostname [::1]` passed the gate and then crashed with ENOTFOUND. Strip brackets at bind-time, keep them for the printed URL. New test asserts the listener actually binds when the operator types `[::1]`. - **`sendPrompt` no transport-close detection**. The chained `entry.connection.prompt()` could hang indefinitely if the `qwen --acp` child wedged or the underlying stream broke mid-flight (the SDK's pending JSON-RPC promise never delivers a response). Because the per-session FIFO tail derives from that promise, a single stuck prompt poisoned every subsequent caller for the same session. Round 4's `channel.exited` is already wired to remove the entry, but the in-flight prompt itself wasn't racing it. Fix: race `entry.connection.prompt(...)` against `entry.channel.exited` inside `sendPrompt`; when the transport closes mid-flight, the prompt fast-fails with a descriptive error rather than hanging the queue. New test exercises this via a stuck fake agent + manual `crash()`. Real correctness: - **`spawnOrAttach` attach-path ignored modelServiceId**. Under `sessionScope:'single'` (default) a client requesting a specific model on attach got `attached:true` while continuing to use whatever model the shared session already had — a silent contract drift. Refactor the per-session `unstable_setSessionModel` call into a shared `applyModelServiceId(entry, modelId)` helper that runs both at create-time (existing path) AND on attach-with-model. Same helper publishes the `model_switched` event so cross-client UIs see the change. New tests cover apply-on-attach and the omit-modelServiceId-on-attach no-op case. Stage 1 design: - **`BridgeClient.{readTextFile, writeTextFile}` raw fs proxy**. The audit flagged that the bridge reimplements file I/O with `fs.{read,write}File` instead of delegating to core's filesystem service — divergence on BOM handling, non-UTF-8 encodings, original line endings. Wiring core's FileSystemService through the bridge is invasive (constructor dep, reaches into core's runtime), and Stage 2's in-process bridge eliminates the proxy entirely. Documented as a known gap with the exact user-visible scenarios; no behavior change in this PR. Test counts: cli serve **116** (was 112, +4); full cli **5070** (was 5066, +4); SDK unchanged at 243. Lint + typecheck green. * fix(cli): PR #3889 review round 7 — match CodeQL suppression to fired query (#3803) Single new CodeQL alert (#201) on `workspaceCwd → spawn({cwd})`. The round-3 suppression I added (`lgtm[js/shell-command-constructed-from- input]`) referenced the WRONG query id — the alert fires the `js/path-injection` query, not the shell-command one. The misnamed suppression also lived 30+ lines above the actual flagged spawn call, out of CodeQL's annotation scope. Move the suppression onto the line immediately preceding the spawn call and use the matching query id `js/path-injection`. The function-level comment block above still documents the Stage 1 trust model rationale (operator-controlled cwd is intentional; agent runs as same UID with shell-tool access; Stage 4+ remote sandbox replaces this factory entirely). Defense-in-depth note added: `workspaceCwd` is canonicalized via `path.resolve()` in `spawnOrAttach` before reaching this factory, and spawn's `cwd` doesn't pass through any shell. No behavior change. Test counts unchanged (cli serve 116, full cli 5070). * fix(cli): self-audit round 8 — concurrency + listener leak + IPv6 + CodeQL honesty (#3803) Multi-round audit pass on PR #3889 commits 5/6/7. Four findings, one real high-severity. High: - Attach-with-modelServiceId had no error recovery and no FIFO. If the agent rejected the new model on attach, `applyModelServiceId` threw, the route 500'd, and the existing session kept running the OLD model — caller sees a 500 with no easy way to detect the state. Worse, two simultaneous attaches with different modelServiceIds would race the `unstable_setSessionModel` calls with no serialization. Add a per-session `modelChangeQueue` (parallel to `promptQueue`); `applyModelServiceId` now chains through it. On failure publishes a `model_switch_failed` event to the bus so OTHER attached clients can see what happened (the failed-caller still gets the 500). Two new bridge tests cover rejection observability + concurrent FIFO. Medium: - `sendPrompt` was adding a `.then` listener to `entry.channel.exited` PER CALL, accumulating linearly with prompt count over a session's lifetime. ~hundreds of bytes per prompt; trivially observable on chatty long-running sessions. Cache a single `transportClosedReject` lazy-init promise on SessionEntry; every subsequent prompt's race uses the same promise. Low: - `[host]:port` IPv6 syntax in `--hostname` was being naively bracket-stripped to `host]:port`, which Node rejects with a cryptic ENOTFOUND at startup. Tighten the strip to only accept pure `[addr]` forms; reject the URL-with-port form upfront with a useful error pointing at `--port`. - `BoundedAsyncQueue.forcedInBuf` invariant comment was wrong: it claimed force-pushed items were always at the front of `buf`, but the eviction-frame path force-pushes at the BACK. The miscount that follows is functionally inert (`close()` blocks the next cap check), but the comment was actively misleading. Rewrote it to honestly describe both call paths and explain why the eviction-case miscount is harmless. CodeQL honesty: - Round 7's `// lgtm [js/path-injection]` comment doesn't actually suppress alerts — GitHub Code Scanning ignores inline `lgtm` annotations (LGTM.com retired 2021). Replaced the misleading `// lgtm` line with a NOTE block stating the constraint explicitly: suppression requires UI dismissal or `.github/codeql/codeql-config.yml`, both out of scope for a code-only PR. The function-level comment that explains the Stage 1 trust model rationale stays. Test counts: cli serve **119** (was 116, +3); full cli **5073** (was 5070, +3, no regressions). * fix(cli): self-audit round 9-10 — reject empty-bracket --hostname (#3803) Final fix from rounds 9-10 of the audit chain. One real concern + three nice-to-have test gaps that the code already handles correctly. - `--hostname '[]'` (empty brackets) used to slip past the bracket validator: `slice(1, -1)` produced `''`, which Node interprets as "bind to all interfaces". An operator typing `[]` clearly meant something specific, not wildcard. Reject the empty-inner case upfront with the same useful error as the `[host]:port` case. New test asserts the rejection. Round 10 ran a clean convergence pass and signed off: - Cross-cutting state invariants (byWorkspace, byId, inFlightSpawns, pendingPermissions, plus all per-entry queues and caches) — all mutations paired and async holes safe. - All test names match assertions. - Public type surface clean (DaemonEvent.id?, Stage1Feature CLI-only, DaemonClientOptions.fetch shape correct). - Production paths verified: non-executable child times out at 10s init, multiple-daemon EADDRINUSE rejects cleanly via `server.once('error', reject)`. - Three "missing test" notes (transportClosedReject cache sharing, full subscribe-publish-evict sequence, modelChangeQueue failure isolation) are diagnostic gaps — the code paths are correct and covered by adjacent tests. Test counts: cli serve **120** (was 119, +1 empty-bracket); SDK unchanged at 243. * docs(cli): note SSE single-line data emit vs multi-line parser (#3803) formatSseFrame emits the payload as a single `data:` line. The EventSource spec also allows a frame to span multiple `data:` lines (joined by `\n` on parse), and the SDK receive-side parser handles that variant — but we never emit it because the JSON payload has no embedded newlines after JSON.stringify. Document the in/out asymmetry so future readers don't mistake the absence of newline splitting for a bug. Closes review thread AMgP0. * fix(cli,sdk): close 11 #3889 review threads — race + leak + IPv6 + SSE Critical correctness: - setSessionModel now serializes through `entry.modelChangeQueue` so POST /session/:id/model can't race with the attach-with-different- modelServiceId path that already chains on the same queue. Without this two concurrent model changes interleave and the published `model_switched` event may not match the agent's actual model. - POST /session reaps the spawned child when the client disconnected during the 1-3s spawn window (`req.aborted && !session.attached`). Without this, every aborted request leaks one orphan child the daemon can't address by sessionId. Attached sessions skip the kill — another client legitimately owns them. - spawnOrAttach refuses dispatch once shutdown has started (`shuttingDown` flag set at the top of `shutdown()`). Late-arrivers on already-established HTTP connections that pass `server.close`'s rejection of NEW connections would otherwise spawn children the shutdown snapshot already missed. Late re-check inside `doSpawn` (after `connection.newSession` resolves) catches the in-flight case and tears down the half-built channel. - sendPrompt early-aborts pre-aborted callers before queuing — saves a queue trip and gives a clean trace for retry-after-abort flows. Defensive: - parseSseStream caps the unread buffer at 16 MiB. Without this, an upstream that returns non-SSE (misconfigured proxy, long-lived non-streaming body) feeds `buf` until the consumer OOMs. - parseSseStream now accepts an optional AbortSignal that is checked at each iteration, and DaemonClient.subscribeEvents forwards `opts.signal` into it. Post-200 aborts now actually stop iteration instead of buffering frames until the upstream closes. - DaemonClient.fetchTimeoutMs (30s default) wraps every short-poll method (health/capabilities/createOrAttachSession/listWorkspaceSessions/ setSessionModel/cancel/respondToPermission) with `AbortSignal.timeout`. Composes with caller-provided signals via `AbortSignal.any`. `prompt` is intentionally exempt (long-lived: model + tool turns can take minutes); `subscribeEvents` is exempt (long-lived SSE). - New `bridge.killSession(sessionId)` API mirrors the shutdown teardown for a single session — used by POST /session orphan-reap above and exposed for future routes that need targeted cleanup. Stale + cosmetic: - Bridge map header comment said "no path that removes a session... when its child process crashes between requests" — out of date since the `channel.exited` cleanup landed in an earlier audit round. Rewritten to describe the actual cleanup chain. - runQwenServe now wraps IPv6 hostname literals in brackets when building the URL (`http://[::1]:4170` not `http://::1:4170`). The bracket-stripping logic on `listenHostname` already handled `app.listen()` correctly; this fixes the printed/copy-paste URL. - Dead `mode: ServeMode` variable in serve.ts removed (the runQwenServe call hardcodes `mode: 'http-bridge'`); the warning condition is now inlined. Test plan: - `vitest run` cli/serve: 120/120 + 49/49 (httpAcpBridge) pass - `vitest run` sdk-typescript daemon: 42/42 pass - tsc --build packages/cli packages/sdk-typescript: clean - ESLint: clean * chore(lint): allow mime/lite in import/no-internal-modules (#3803) `packages/core/src/utils/fileUtils.ts` and its test import `mime/lite`, which is mime@4's documented public sub-export (a smaller bundle that omits the legacy mime DB) — not an internal module. The rule has been flagging these on PR CI runs even though main's CI happens to pass (likely stale-cache vs fresh-install timing). Add `mime/lite` to the allowlist so lint is consistent across main and PR runs. * fix(cli,sdk): close 14 review threads — env whitelist + races + Windows tests + structured errors (#3803) Critical correctness: - registerPending now resolves orphaned permissions as cancelled when the entry has been torn down between the agent's `requestPermission` decision and the bridge handler firing. Previously the permission would hang the agent forever (killSession's pendingPermissionIds iteration didn't include the just-orphaned id, shutdown's clear() dropped it without resolving). - Workspace key now goes through `realpathSync.native` (with a resolved-but-uncanonicalized fallback for non-existent paths) so case-insensitive filesystems (macOS APFS, Windows NTFS) don't silently degrade `sessionScope: 'single'` into "one session per spelling". Matches how `config.ts` / `settings.ts` / `sandbox.ts` resolve workspace paths. - killChild gets a hard 10s deadline after SIGKILL so a child stuck in uninterruptible sleep (D-state, e.g. NFS read on a dead server) can't block `bridge.shutdown()`'s `Promise.all` forever. `SHUTDOWN_FORCE_CLOSE_MS` in `runQwenServe` only covers `server.close()` — without this hard kill, daemon shutdown hangs. - setSessionModel now races the agent call against `transportClosedReject` and wraps in `withTimeout`, matching what `sendPrompt` and `applyModelServiceId` already do. Without the race, a wedged child blocks `POST /session/:id/model` forever. Also publishes a `model_switch_failed` SSE event on rejection so passive subscribers see the failure (matches `applyModelServiceId`). - shutdown() now awaits `inFlightSpawns` so the late-shutdown re-check inside `doSpawn` finishes its half-built channel teardown before `bridge.shutdown()` resolves. Without the await, `runQwenServe.close()` returns and `process.exit(0)` is queued before the orphan tears itself down, surfacing a stderr error AFTER the daemon claimed graceful shutdown. - sendPrompt re-checks `signal.aborted` immediately after `addEventListener` so a microsecond-window synchronous abort that fires between the early-exit check and listener registration still triggers the agent `cancel` notification. Security: - `defaultSpawnChannelFactory` now passes an *allowlisted* environment to the spawned `qwen --acp` child instead of `{ ...process.env }` with `QWEN_SERVER_TOKEN` deleted. The agent runs user-supplied prompts with shell-tool access; anything in its env (OPENAI/ ANTHROPIC/DASHSCOPE keys, AWS/GCP credentials, DB passwords, OAuth tokens) is reachable by prompt injection. Allowlist covers HOME/PATH/USER/LOGNAME/LANG/LC_*/TMPDIR/TEMP/TMP/NODE_PATH plus Windows essentials (SYSTEMROOT/USERPROFILE/APPDATA/...). The explicit `delete childEnv['QWEN_SERVER_TOKEN']` stays as defense-in-depth — anyone grepping for the token name finds the scrub explicitly named. Observability: - 5xx responses now carry structured `code` and `data` fields when the underlying error has them (JSON-RPC errors from the ACP SDK forward as `{code, message, data}`). Without this, every distinct failure (quota / rate-limit / auth / crash) collapses to the same opaque "Internal error" string at the client. - 5xx errors log to stderr (via `writeStderrLine`, not `console.error`, to keep the no-console lint rule happy). Stop-gap until structured access/error logging lands. - Eviction frame on EventBus subscriber overflow no longer consumes a `nextId` slot. The synthetic frame burning a sequence id meant healthy subscribers saw gaps (3 → 5) that the resume ring couldn't back-fill — silently broke the `BridgeEvent.id` "monotonic per- session" contract. `BridgeEvent.id` is now optional on the type to make the absence honest. Same pattern as `stream_error`. Cross-platform: - httpAcpBridge.test.ts now derives expected paths via `path.resolve(path.sep, 'work', 'a')` (factored out as `WS_A`/ `WS_B`/`SESS_A` constants) instead of hardcoded POSIX literals like `/work/a`. On Windows `path.resolve('/work/a')` returns `D:\work\a` so the literal expectation drifted; the bridge's internal canonicalization to that form was correct, the tests were wrong. Fixes 3 Windows CI matrices that have been red since the PR opened. Compatibility: - `DaemonClient.fetchWithTimeout` now feature-detects `AbortSignal.timeout` and `AbortSignal.any` with polyfills, so the SDK actually works on its declared minimum runtime (Node >=18.0.0). `AbortSignal.any` was added in Node 20.3 — without the fallback every non-streaming call throws on Node 18.0–20.2. Documentation: - `cancelSession` now explicitly documents that cancel only affects the currently active prompt; previously POST'd queued prompts continue to execute. Multi-prompt queueing is a daemon-introduced behavior (not in ACP spec), so the contract for queued prompts is ours to define and was previously implicit. - Removed misleading "still reliable on Node 20" comment around `req.aborted` and switched the orphan-cleanup signal to `res.writable` — the right "can we still send a response to this client?" check (`req.destroyed` is too eager: clients close their writable end after sending the body even though they're still listening for the response). * fix(cli): close 3 more review threads — case-insensitive Host, trim token, sliceLineRange (#3803) - hostAllowlist now lowercases the Host header before comparison. Per RFC 7230 §5.4 Host is case-insensitive; Express normalizes header *names* but not values, so a Docker proxy that capitalizes the hostname (`Host: Localhost:4170`) or a platform with case-preserving DNS (`HOST.docker.internal`) was getting 403 with an exact-match compare. - `runQwenServe` now `.trim()`s the token from both `--token` and `QWEN_SERVER_TOKEN`. Common gotcha: `export QWEN_SERVER_TOKEN=$(cat token.txt)` keeps the file's trailing `\n`, so the hashed-then- compared token never matches what well-behaved clients send. Every request returns the generic 401, no breadcrumb pointing at the whitespace, operators chase ghosts. - `BridgeClient.readTextFile` partial-read path no longer `content.split('\n')`s the entire file. New `sliceLineRange` walks `indexOf('\n', …)` forward only to the end-of-range boundary and returns a single substring. For a 100 MB file with `{line: 1, limit: 2}` this avoids a ~100 MB `String[]` allocation. * fix(sdk): close 2 #3889 polyfill leaks — abortTimeout + composeAbortSignals Two copilot review threads on commit 11567a43c's AbortSignal polyfill code: - `abortTimeout` polyfill scheduled `setTimeout` but never cleared it. Even after the awaited fetch resolved, the pending timer kept the event loop alive until it fired; on a heavily-used client the per-call timers accumulated. Fix: `.unref()` the handle (so a fast-resolving fetch doesn't pin the loop) AND clear it on the controller's `abort` event (so the composed-signal-aborted-first path also drops the timer). Defensive `typeof handle.unref` so the polyfill works in any runtime that returns a non-NodeJS Timeout shape. - `composeAbortSignals` polyfill added an `abort` listener to every input signal but never removed them. Long-lived caller signals (e.g. a session-scope cancel signal that lives for the whole SDK client) accumulated one listener per SDK call — slow leak that retained the closure + controller of every prior call. Fix: track per-input cleanups in an array, detach all on the first abort (whichever input fires) AND on the composed controller's own abort path (defense-in-depth for callers that abort the composed signal independently). Both leaks only fire on the polyfill path — runtimes with native `AbortSignal.timeout` / `AbortSignal.any` (Node 20.3+) take the early-return path and bypass the leak surface entirely. 29/29 DaemonClient.test.ts pass; tsc + ESLint clean. * fix(cli,sdk): close 13 deepseek review threads — error handling + race + log noise (#3803) Correctness: - `applyModelServiceId` now races against `transportClosedReject` like `setSessionModel` and `sendPrompt` already do, so a child crash during attach-with-different-model fails fast instead of waiting the full 10s `withTimeout`. - `POST /session` disconnect guard now handles the `attached` case: previously `!res.writable && session.attached` fell through to `res.json` and threw EPIPE through Express's default handler. - `POST /session/:id/prompt` now drops `AbortError` silently. When the HTTP client closes mid-prompt the bridge re-throws as `AbortError`; routing it through `sendBridgeError` produced a noisy 500 + stderr stack trace that under active use generated dozens of misleading log lines per second. - `POST /session/:id/prompt` now rejects empty arrays (`[]`) and non-object elements with a 400 instead of letting the ACP SDK surface 500s on degenerate input. - `readTextFile` rejects `limit <= 0` up front (previously `sliceLineRange` hit the `end < start` path with surprising results). - `inFlightSpawns` tracks ALL `doSpawn` promises now, not just single-scope ones. Under `thread` scope, `shutdown()` previously resolved before in-flight spawns finished their child cleanup, surfacing stderr noise after the daemon claimed graceful shutdown. Use a unique `${workspaceKey}#${randomUUID()}` key per thread-scope spawn so simultaneous spawns don't collide. Shutdown ordering: - The 5s force timer is now armed AFTER `bridge.shutdown()` resolves, so it only races `server.close()` (the listener drain) — not the bridge's own 10s `KILL_HARD_DEADLINE_MS` child cleanup. The earlier arrangement could resolve this promise while the bridge was still killing children, orphaning anything not yet at the deadline. Express error handling: - Final 4-arg error middleware catches `express.json()`'s `SyntaxError` on malformed bodies and returns JSON `400` instead of Express's default HTML page (which trips SDK clients that expect a JSON body on every response). - SSE `res.on('error')` handler now logs the error before cleanup, so operators get a breadcrumb for flaky-network triage instead of silent disconnect. Performance: - `ALLOWED_CHILD_ENV_KEYS` moved to module scope so the 22-element Set is allocated once at load instead of rebuilt on every `defaultSpawnChannelFactory` call. (Renamed from `ALLOWED_ENV_KEYS` for clarity.) Documentation: - `canonicalizeWorkspace` now explicitly notes the cross-module contract with `config.ts`/`settings.ts`/`sandbox.ts`. A shared utility was considered but deferred — the call sites use slightly different fallback policies and Stage 2 in-process collapses the bridge into core, removing the bridge-side path resolution entirely. Tests: - Two new DaemonClient tests exercise `fetchWithTimeout`'s AbortSignal.timeout / composeAbortSignals polyfill paths against a never-resolving fetch promise. Previously every test used `recordingFetch` with synchronous resolution, so those polyfills shipped untested — a logic error there would only surface when a real daemon became unresponsive. * docs(serve): close §08 Stage 1 doc gap — user guide + protocol reference + DaemonClient example (#3803) Stage 1 of issue #3803 §08 budgeted "Documentation + examples + e2e tests" as the closing 1d task. The e2e tests landed (22 cases under integration-tests/cli/), the docs did not. After merge, anyone who discovers `qwen serve` via `qwen --help` had nowhere in-repo to read about it — the only complete description lived on the PR page itself. This commit fills that gap with three complementary docs and a README mention: - `docs/users/qwen-serve.md` — operator-facing quickstart: 5-step curl walkthrough (start → /health → /capabilities → /session → /prompt → /events), CLI flag table, default-deployment threat model summary, and a pointer to the orchestrator-shaped multi-session future. - `docs/developers/qwen-serve-protocol.md` — full HTTP protocol reference: per-route request/response shapes, auth contract, error envelope, SSE frame format and event-type table, Last-Event-ID reconnect semantics, environment variables, source layout. - `docs/developers/examples/daemon-client-quickstart.md` — TypeScript end-to-end snippet with the SDK's DaemonClient: capabilities probe, spawn-or-attach, subscribe-before-prompt event handling, reconnect via Last-Event-ID, first-responder permission voting, shared-session collaboration between two clients, auth, cancel. - README.md — "Daemon mode" added to the 5-way usage list + a short section under Usage with three doc links. - `docs/users/_meta.ts` and `docs/developers/_meta.ts` — sidebar entries for the new pages. No code changes; no test changes. * docs(serve): close 8 deepseek doc-review findings (#3803) Inline doc review on the Stage 1 doc set caught real issues: - `qwen-serve-protocol.md`: `session_died` (and `client_evicted`, `stream_error`) now explicitly marked as terminal — SSE stream closes after the frame; subscribers should reconnect via POST /session for `session_died`. - `qwen-serve-protocol.md`: documented coalesced spawn failure path — when the underlying spawn fails, all coalesced callers receive the same error and the in-flight slot is cleared so a follow-up call can retry. - `qwen-serve-protocol.md`: clarified the `modelServiceId` (back-end provider, picked at session create) vs `modelId` (model within an already-bound service, picked via POST /session/:id/model) distinction, and explained why `/capabilities`'s `modelServices` array is always `[]` in Stage 1. - `qwen-serve-protocol.md`: typo "Re-races" → "Races" on the model switch description. - `qwen-serve.md`: reordered quickstart so SSE subscribe (now step 4) comes before the prompt POST (now step 5). Previously, step 4's blocking prompt resolved before step 5's `curl -N` was open, so readers following the steps verbatim never saw a streaming event. Also expanded the event-types paragraph to call out which frames are terminal. - `daemon-client-quickstart.md`: closed a TOCTOU race in the example — `sendPrompt` fired before the SSE handshake completed, so fast-starting agents could emit events into the ring before the iterator was actually pulling. Pass `lastEventId: 0` so the daemon's replay buffer covers the gap; comment in the example explains the rationale. - README.md: "Loopback bind has no auth" → "no auth by default" (since the user can opt into bearer auth on loopback by setting `QWEN_SERVER_TOKEN`). * fix(cli,sdk,docs): close 21 review threads — env regression + races + doc accuracy (#3803) CRITICAL regression fix: - Child env scrub flipped from allowlist back to denylist (just QWEN_SERVER_TOKEN). The earlier allowlist was overzealous: it dropped OPENAI_API_KEY / ANTHROPIC_API_KEY / GEMINI_API_KEY / QWEN_* / DASHSCOPE_API_KEY / custom modelProviders[].envKey, all of which the agent legitimately needs to authenticate to the LLM. Daemon-mode users with env-only auth would start the daemon, attach a session, then watch every prompt fail with auth errors. Threat- model rationale documented at the call site: prompt-injected shell tools can already read ~/.bashrc, ~/.aws/credentials, etc., so env passthrough isn't the security boundary; the user-as-trust-root is. QWEN_SERVER_TOKEN stays scrubbed to prevent agent → its own daemon escalation. Other code fixes: - doSpawn no longer tears down the session when create-time model switch fails. The session is still operational on the agent's default model; tearing it down left the caller with a 500 and no sessionId to retry against. The model_switch_failed SSE event is the visible signal; caller can retry via POST /session/:id/model once they have the sessionId. - doSpawn now uses applyModelServiceId for the create-time model switch (was raw conn.unstable_setSessionModel + withTimeout). The helper races against transportClosedReject too, so a child crash during model switch fails fast instead of consuming the full init timeout. - sendPrompt's abort handler now calls cancelPendingForSession before the ACP cancel notification (matching cancelSession). A client disconnecting mid-permission was leaving the agent stuck waiting on a vote that no SSE subscriber would ever cast. - shutdown() and killSession() now publish a terminal `session_died` SSE event before closing the bus. Previously the channel.exited handler's "byId.get(...) !== entry" guard short-circuited (entry already removed), so SSE subscribers couldn't tell daemon shutdown from a transient network error. - Express error middleware now special-cases `status: 413` (EntityTooLargeError from body-parser when a request exceeds the 10 MB JSON limit) and returns a JSON 413 instead of a misleading 500. - /health is now registered BEFORE bearerAuth middleware, so liveness probes work without credentials when the daemon was started with --token. CORS deny + Host allowlist still apply. - SSE writes serialize through a per-connection chain so the heartbeat interval can no longer interleave with the main event- write loop. Two concurrent res.write calls would otherwise bypass the backpressure guard and could interleave bytes between SSE frames on the wire. SDK: - abortTimeout / composeAbortSignals exported for direct unit testing. The existing test claimed to cover the polyfill paths via subscribeEvents, but subscribeEvents calls _fetch directly (not fetchWithTimeout), so composeAbortSignals never ran in the test. New tests exercise the helpers directly across native + polyfill runtimes. Doc accuracy fixes: - daemon-client-quickstart.md: createOrAttachSession({ cwd: ... }) → ({ workspaceCwd: ... }) (SDK type), client.sendPrompt → prompt, client.cancelSession → cancel. The example wouldn't typecheck. - qwen-serve.md: "binds one workspace" claim removed — a single daemon hosts sessions for any cwd the caller passes; the per-instance constraint is per-user / scale, not per-workspace. Auth verification example switched from /health to /capabilities (since /health is now exempt from bearer auth). - qwen-serve-protocol.md: env var was QWEN_E2E_LLM, real var is SKIP_LLM_TESTS (inverted polarity). Streaming test count was 4, actually 3. Added Stage 1 limitation notes for "no DELETE /session" and "no permission timeout". Added client-side ring-buffer gap detection guidance for Last-Event-ID reconnect. Test updates: - httpAcpBridge.test.ts: rewrote two tests for the new doSpawn-on-model-switch-fail contract (publish event, keep session). Updated shutdown-closes-subscriptions test to expect the new terminal `session_died` frame. - server.test.ts: switched bearer-auth rejection probes from /health to /capabilities (since /health is now exempt). Added a test that locks /health's exemption. * docs(serve): close 2 last review threads — prompt timeout limitation note (#3803) A05Yk (deepseek): document that `POST /session/:id/prompt` has no server-side timeout. The bridge only races against the agent child exiting + the caller's HTTP-disconnect AbortSignal; a wedged-but-alive agent blocks the per-session FIFO. Long-running prompts are legitimate (deep research / large-codebase analysis) so a default deadline is deliberately not set; Stage 2 will expose a configurable opt-in. Callers should set their own client-side timeout and disconnect / POST /session/:id/cancel on expiry. AyoUy (copilot): same env-allowlist concern as A09HB — already addressed by the allowlist→denylist revert in the previous commit (e74aa9919). No additional code change needed; the resolve here just acks that the upstream fix covers it. * fix(serve): close 3 copilot review threads — SSE envelope shape + integration test ordering (#3803) A8uSe / A8uSt — the SSE frame examples in qwen-serve.md and qwen-serve-protocol.md showed `data:` containing only the inner ACP payload (e.g. `{"sessionUpdate": ...}`). The daemon actually emits the full event envelope — `{id?, v, type, data, originatorClientId?}` — JSON-stringified on a single line. Readers copying the curl output and writing parsers against the documented shape would extract garbage or fail JSON-shape validation. Both docs now show the real envelope and call out the SSE-level `id:` / `event:` lines as EventSource convenience that duplicates fields already inside the JSON envelope. A8uSz — integration `qwen serve — bearer auth` tests probed `/health` for 401 assertions, but `/health` is now intentionally registered BEFORE the bearer middleware (per the A8dZT fix in the previous commit) so liveness probes work without credentials. Switched probes to `/capabilities`, plus added a `/health exempt` test that locks the exemption so a future middleware ordering change can't silently break liveness probes. Also: integration `bad modelServiceId tears down half-init session` asserted the OLD doSpawn-on-model-switch-fail behavior (throw + clear maps). Per #3889 review A05Ym the new behavior keeps the session operational on the agent's default model and surfaces the failure via the `model_switch_failed` SSE event. Test renamed to `bad modelServiceId keeps the session alive on the default model` and rewritten to assert the new contract. * fix(serve): close 3 copilot review threads — sync write throw, polyfill name, blockquote (#3803) A800o (server.ts:360): `res.write(chunk, cb)` callback isn't documented to receive an error argument in Node — errors come on the `'error'` event, which the surrounding code already wires up. The dead `(err) => if (err) reject(err)` branch was misleading. The real concern was that `res.write()` can throw synchronously when the socket is already destroyed (typical EPIPE shape), and the throw escaped the promise executor. Wrapped the `res.write` call in try/catch so that surfaces as a rejection on the returned promise instead of an unhandled exception. A8008 (DaemonClient.ts:375): `abortTimeout` polyfill called `new DOMException('TimeoutError')`, which sets the *message* to "TimeoutError" and leaves `name` at its default ("Error"). Native `AbortSignal.timeout()` aborts with `name === 'TimeoutError'` (per WHATWG), so callers doing `if (err.name === 'TimeoutError')` to distinguish timeout from user-abort would see the polyfill behave differently from the native runtime. Constructor signature is `new DOMException(message, name)` — fixed both args. A801J (qwen-serve-protocol.md:254): blockquote was broken — one line in the middle of the multi-line `>` block was missing the `>` prefix, which dropped the rest of the list out of the quote and rendered awkwardly. Added the missing `>`. * fix(cli,sdk): close 8 review threads — DoS cap + SDK plumbing + cleanup (#3803) Critical: - A9UEi — `EventBus` had no subscriber cap and evicted subscribers lingered in the `subs` Set until the consumer drove `next()`. An attacker opening thousands of SSE connections to one session would amplify each `publish()` (O(N) over subs) into a CPU/memory DoS, with each evicted-but-stalled connection's `BoundedAsyncQueue` pinned in memory forever. Two fixes: per-bus subscriber cap of 64 (refuses new subs at the limit by returning an empty iterable), AND `subs.delete(sub)` immediately when a subscriber is evicted so subsequent publishes don't pay the dead-sub iteration cost. Also set `server.maxConnections = 256` on the listener to bound socket descriptors against connections that never finish their headers. SDK: - A9UEv — `prompt()` now accepts an optional `AbortSignal`. Caller cancellation forwards through the underlying TCP close, which the daemon already translates into an ACP `cancel` notification. The bridge's `sendPrompt(sessionId, req, signal)` always supported it; only the SDK surface was missing the parameter. - A9UEn — `subscribeEvents` now applies `fetchTimeoutMs` to the CONNECT phase only (request → headers received). The SSE body itself stays uncapped (it's long-lived by design), but a daemon that's TCP-open but never returns headers no longer blocks callers indefinitely. Implementation: a setTimeout-driven AbortController composed with the caller's signal, cleared in `finally` once `_fetch` returns. - A9UEr — `respondToPermission` now drains the response body via `res.body?.cancel()` on both 200 and 404. undici keeps the underlying socket pinned waiting for an unconsumed body; long- running clients with frequent permission votes would exhaust the connection pool. Cleanup: - A9UNF — `MAX_BUF_BYTES` renamed to `MAX_BUF_CHARS` (the guard checks `buf.length`, which is UTF-16 code units, not bytes). The cap's job is "stop runaway non-SSE bodies", not exact accounting, so the proxy is intentional — but the name now matches the unit. Error message updated. - A9UNb / A9UNp — both integration tests' boot-timeout `setTimeout` is now stored and `clearTimeout`'d on success and on early exit. Without the clear the un-cancelled 10s timer outlived the spawn promise and could keep the vitest event loop alive past the test, manifesting as intermittent timeouts on slow CI. A9UEy was already addressed by the prior commit's `status === 413` branch in the Express error middleware (body-parser sets both `status: 413` and `type: 'entity.too.large'` on body-too-large errors); resolve only. * fix(cli,test): close 2 copilot review threads — case-insensitive bearer + Windows skip (#3803) A9sCe (auth.ts:88): bearer scheme parsing was case-sensitive (`parts[0] !== 'Bearer'`). Per RFC 7235 §2.1 / RFC 7230 §3.2.6 the auth scheme token is case-insensitive — `Bearer` / `bearer` / `BEARER` are all valid, and conformant clients may send any. The old code returned 401 on those. Switched to a regex-based split that also tolerates runs of whitespace between scheme and credentials, then `.toLowerCase()`s the scheme before comparing. The token value itself stays case-sensitive (it's user-defined opaque material). A9sCw (qwen-serve-streaming.test.ts): the streaming integration suite shells out to `pgrep` / `kill -KILL` to simulate child-process crashes for the `SIGKILL → session_died` test. Those binaries are POSIX-only — on Windows runners the suite would fail even when `SKIP_LLM_TESTS` is unset. Added `process.platform === 'win32'` to the SKIP gate. A Windows-equivalent (`taskkill /F /PID …`) needs different scaffolding; deferred. * fix(cli,sdk,docs): close 6 review threads — CodeQL regex, body cancel, env doc (#3803) A90nk (auth.ts:93): CodeQL flagged the new bearer-scheme regex `^(\S+)\s+(.+)$` as a polynomial-regex risk on user-controlled input — `\s+` and `.+` overlap on whitespace-heavy adversarial headers (the alert example: `'!\t' + '\t'.repeat(N)`). Replaced with a hand-rolled split (`indexOf(' ')` + manual whitespace skip) so there's no backtracking. Behavior unchanged: scheme is still case-insensitive, runs of whitespace between scheme and credentials still tolerated, scrubs `header.charCodeAt() === 0x20` explicitly so we don't accidentally consume tab/newline as scheme separator. A90oi / A96Q8 (qwen-serve.md:117): the threat-model bullet still claimed the spawned child runs with an "allowlisted environment" (HOME / PATH / USER / LOGNAME / LANG / etc), but the prior commit flipped the implementation to a denylist (only `QWEN_SERVER_TOKEN` scrubbed) so the agent could authenticate to LLM providers. Doc now matches code: explicit pass-through with a one-key scrub, plus the threat-model rationale (user-as-trust-root, env passthrough is not the boundary). A90ou (qwen-serve-protocol.md:300): `stream_error` example showed the inner ACP-style payload `{"error":"<message>"}` instead of the full envelope `{v, type, data:{error}}` that other SSE-frame examples in the same doc already use. Updated to match. A96RL (DaemonClient.ts:352): `subscribeEvents` threw on a 200 with the wrong content-type without consuming the response body first. On undici-backed `fetch` an unconsumed body keeps the underlying socket pinned waiting for the consumer; long-running clients hitting this path repeatedly would exhaust the connection pool. Same `await res.body?.cancel()` pattern as `respondToPermission`. A96RR (server.ts:167): prompt-element validation accepted any non-null object, but `typeof [] === 'object'`, so `prompt: [[]]` slipped past with a confusing 500 from the ACP SDK layer downstream. Added `!Array.isArray(item)` so the 400 actually catches array elements. * fix(cli,sdk,docs): close 10 review threads — DoS observability + race + tests (#3803) Code: - A-Ur8 (httpAcpBridge.ts:1319): SCRUBBED_CHILD_ENV_KEYS gets a prominent WARNING that the denylist-only design is correct ONLY because the agent has unrestricted shell-tool access. Any future sandbox-locked variant MUST switch back to allowlist or expand the denylist to cover provider/CI/cloud secret prefixes. - A-XfH (auth.ts:60): Host allowlist now accepts the no-port form (`localhost`, `127.0.0.1`, `[::1]`, `host.docker.internal`) when the bind port is 80. Per RFC 7230 §5.4 clients may legitimately omit the port suffix when it matches the URI scheme default. - A-UsJ (httpAcpBridge.ts:564): unify model-switch failure handling. The create-session path swallows the error to keep the session alive on its default model; the attach path now does the same (was: throwing a 500 with no sessionId, denying the caller any way to recover). Both paths surface failure via the `model_switch_failed` SSE event. - A-UsN (httpAcpBridge.ts:621): extracted the lazy-init `transportClosedReject` pattern into `getTransportClosedReject` helper. Three call sites (`applyModelServiceId`, `sendPrompt`, `setSessionModel`) collapsed to one, single-listener invariant documented at one place. - A-UsH (eventBus.ts:194): subscriber-cap rejection is now observable. EventBus.subscribe throws a typed `SubscriberLimitExceededError` (was: silent empty iterable). SSE route catches it, logs to stderr, and emits an SSE-shaped `stream_error` terminal frame so the rejected client sees a readable failure rather than a closed-with-no-frames stream. - A-UsO (server.ts:72): `/health` is now exempted from bearerAuth ONLY on loopback binds. On non-loopback the route is registered AFTER bearerAuth so probes must carry the token — otherwise an unauthenticated caller could probe arbitrary IP:port to confirm a `qwen serve` exists. Doc updated. Tests added: - A-UsP: new test sends an 11 MB body to verify the 413 path in the Express error middleware returns the actionable "Request body too large" JSON instead of a generic 500. - A-UsQ: new test for `DaemonClient.prompt(sessionId, req, signal)` AbortSignal forwarding through to fetch. - A-UsS: two new tests for `subscribeEvents` connect-timeout (never-resolving fetch aborts; fast-resolving fetch clears the timer so it doesn't leak as a dangling handle). - A-UsU: new test for `sendPrompt` abort path resolving pending permissions as cancelled — the bug being regressed: an HTTP client disconnecting mid-permission would leave the agent stuck waiting on a vote that no SSE subscriber would ever cast. Test contract updates: - `publishes model_switch_failed and surfaces the error when the agent rejects` rewritten for the new attach-path swallow contract: attach now returns the existing session with `attached: true` and the `model_switch_failed` event is the visible failure signal instead of a thrown error. * fix(serve): add missing v field on subscriber-limit stream_error frame (#3803) `tsc --build` (which CI runs as part of the lint job) caught what `tsc --noEmit` (the local typecheck script) missed: the new `stream_error` frame in `server.ts:344` was constructed without the `v` field, but `OmitId<BridgeEvent>` requires it. Local typecheck in the previous commit was clean; the build's stricter project graph reported `error TS2345` and broke both Lint and Test (Ubuntu) jobs. Set `v: 1` to match the existing `stream_error` construction in the SSE iterator-throw path in the same file. * docs(users): close 1 copilot review thread — GitHub canonical casing in nav (#3803) A_U2e: nav label "Github Actions" was inconsistent with the canonical "GitHub" casing used elsewhere in the repo (skills, README, etc.). Rename to "GitHub Actions" for consistent branding. Pre-existing entry in `docs/users/_meta.ts` adjacent to the `'qwen-serve'` line this PR added — flagged in the diff context. * fix(serve): close 4 deepseek review threads — closed-bus race + per-session stderr + entry override (#3803) BBb9H (correctness): `BridgeClient.requestPermission` could orphan a pending permission if the bus closed between `registerPending` and `entry.events.publish` (the shutdown path closes per-session buses BEFORE awaiting `channel.kill()`, so the agent can still issue `requestPermission` in that window). Pending was registered in the daemon-wide map but `publish()` returned `undefined` (closed bus) → no SSE subscriber ever saw the request → no client voted → agent's `requestPermission` hung forever, blocking the daemon's `Promise.all` over child kills. Now: check publish's return; if `undefined`, roll back the pending via a new `rollbackPending` callback that resolves it as `cancelled`. BBb8e (Critical observability): child stderr was `'inherit'` — all sessions' stderr interleaved on the daemon's stderr stream unattributed. Switched to `'pipe'` and forward each line with a `[serve pid=<n> cwd=<dir>]` prefix; operators can now `grep pid=12345` to pull one session's trace cleanly. Updated the now-stale doc comment that claimed inherit was current. BBb8- (deployability): `process.argv[1]` is brittle — fails on non-`qwen` launchers (bundled binaries, npx wrappers, `node -e`, `tsx`, container images that relocate the script). Added `QWEN_CLI_ENTRY` env override as the higher-priority resolution path. Improved the failure message to suggest the env var as the actionable fix. BBb82 (documented limitation): `withTimeout` REJECTS but doesn't ABORT the underlying ACP op. For `unstable_setSessionModel` this means a timed-out caller perceives failure while the agent may eventually complete the switch — drift between caller's perceived model and agent's actual model + contradictory SSE events. Documented as a Stage 1 limitation in the `withTimeout` JSDoc; acceptable because (1) ACP doesn't expose a cancel signal for `unstable_setSessionModel` yet so we couldn't abort even if we wanted to, (2) model switches complete in milliseconds in practice — a timeout means genuinely wedged, not just slow. Stage 2 will add abort plumbing once ACP exposes the hook. * ci(noop): re-trigger workflow for f8509dde5 (#3803) * fix(cli,sdk): close 8 review threads — sse abort + queue drain mode + perf + doc engine drift (#3803) Correctness: - BCcd6 (sse.ts:80): trailing flush at EOF used `splitFrames(buf)` which returned `[buf]` — a multi-byte split that completed multiple frame separators in the final `decoder.decode()` would merge the frames into one parse and silently drop events. Switched the EOF flush to `consumeFrames()` (same walker the main loop uses), then attempt one more `parseFrame` on any trailing fragment. Removed the now-unused `splitFrames` helper. - BCybH (sse.ts:67): `parseSseStream` only checked `signal.aborted` before each `reader.read()`, leaving the generator parked inside a pending `read()` if the upstream went idle right when the caller aborted — contradicting the docstring's "AbortSignal cleanup is prompt" claim. Added a one-shot abort listener that calls `reader.cancel()` (cleared in `finally`), so abort reliably terminates even on a stalled stream. - BCce_ / BCycT (eventBus.ts:391/253): subscribe documented "abort closes the iterator promptly" but `BoundedAsyncQueue.next()` drained any items already in `buf` before honoring `closed`. Aborted SSE subscribers could keep yielding hundreds of queued events to a closed socket. Added a `close({drain: false})` mode that truncates `buf` immediately, used by the abort path; the default drain-on-close behavior is preserved for the eviction path (which needs the synthetic `client_evicted` terminal frame to reach the consumer before the iterator unwinds). Performance: - BCcfe (auth.ts:72): `hostAllowlist` was allocating a fresh `Set` + 4 interpolated strings on every request. Cache once per resolved port (relevant because tests bind to ephemeral 0 and the port is only known after `listen()`); SSE heartbeats and high-frequency probes now skip the allocation. - BCcgJ (DaemonClient.ts:137): `fetchWithTimeout` used `AbortSignal.timeout()` — the timer fires regardless of whether the fetch resolved early. On a fast-resolving request with the default 30s timeout, the pending timer hangs around. Switched to `AbortController` + `setTimeout` + explicit `clearTimeout` in `finally`, so each timer is released the moment its fetch settles. Also `.unref()`s the timer so it doesn't pin the event loop on its own. Doc accuracy: - BCyc0 (DaemonClient.ts:468): the `abortTimeout` / `composeAbortSignals` JSDoc claimed Node 18-20.2 polyfill compatibility, but `engines.node` is `>=22.0.0` now. Reframed as a generic feature-detect for non-Node runtimes (browsers / edge workers) so future maintainers don't reason about the wrong floor. - BCydi (server.ts:368): "Always present in Node >= 20" → "on the supported Node versions (engines.node >=22)". CodeQL alert #207 (httpAcpBridge.ts:1342, `js/path-injection` on `cwd: workspaceCwd`) is the renumbered version of the already-accepted #201 — same trust-model rationale documented at the call site, same need for maintainer UI dismiss / config exclusion. * feat(serve): close 3 chiga0 audit items — ringSize 4000, --max-sessions, /health?deep=1 (#3803) Three "30-minute" items from chiga0's external architecture audit (2026-05-11). All actionable within Stage 1 scope; remaining items in chiga0's review (SaaS positioning, multi-token to Stage 1.5, acp-bridge package extraction, reference orchestrator) are larger scoping decisions deferred to Stage 1.5/2. DEFAULT_RING_SIZE 1000 → 4000 (Risk 4): - A single long turn can emit hundreds of frames (test plan reports 13 for a SHORT turn, real workloads can be 10× that). 1000 was exhausted by a moderate turn before a 5s reconnect window finished. 4000 gives ~30× headroom over a typical busy turn at the cost of a few hundred KB RAM/session. Updated user + protocol docs and the daemon-client-quickstart example. --max-sessions <n> (default 20) (Rec 3): - New `ServeOptions.maxSessions` + matching `BridgeOptions`. Bridge throws `SessionLimitExceededError` when `byId.size + inFlightSpawns.size >= max` BEFORE issuing a fresh spawn. Attaches to existing sessions (single scope) bypass the cap so an idle daemon's reconnects keep working at-capacity. `0` disables. Default of 20 sized below the design's N≈50 cliff (per-session ~30–50 MB RSS + FD pressure). HTTP route maps to 503 with `Retry-After: 5` and `code: session_limit_exceeded`. Tests cover: cap rejection under thread scope, attach-not-counted under single scope, `0` disables. Documented in CLI flags table + protocol Common-error section. /health?deep=1 (Risk 3): - Default `/health` stays cheap (no bridge access). With `?deep=1` the response includes `sessions` and `pendingPermissions` from the bridge — touches state so a wedged bridge surfaces as 503 `{status: "degraded"}` instead of "200 ok" on a zombie daemon (the `k8s rolling deploy will see healthy` failure mode chiga0 flagged). Loopback-vs-non-loopback bearer-exempt logic from the earlier A8dZT fix is preserved via a shared handler. Tests cover: cheap default, deep response shape, throwing-getter → 503. * fix(serve,sdk,docs): close 9 review threads — req.on('close') prompt-cancel bug + doc + types (#3803) Critical correctness: - BQAnZ (server.ts:225): `POST /session/:id/prompt` wired cancellation to `req.on('close')` — but Node's `IncomingMessage` fires that event when the request body has been fully consumed, even when the client is still listening for the response. Result: ordinary prompt calls were getting cancelled the moment their upload finished, returning `{stopReason: "cancelled"}` instead of completing. Switched to `res.on('close')` guarded by `!res.writableEnded` (the documented "client gave up before we could send the response" pattern, same as the POST /session disconnect-detection from earlier in the PR). Already addressed earlier — resolve as ack: - BQAna (httpAcpBridge.ts:767): no global session cap. Already shipped in commit 66ffd7cc6 — `--max-sessions` flag + bridge enforces with `SessionLimitExceededError` mapped to 503; both in-flight spawns and live sessions count against the cap. Doc fixes: - BDAOf (DaemonClient.ts:49): `fetchTimeoutMs` JSDoc said it applies to "every non-streaming method including prompt", but `prompt()` actually bypasses fetchWithTimeout (model+tool turns are minutes-scale, can't be 30s-capped). Doc now lists the short-lived methods explicitly and notes prompt's exemption. - BDAPY (qwen-serve-protocol.md:283): blockquote was broken — the `POST /session/:id/cancel` line was missing the leading `>` and a stray "- POST /session/:id/cancel." rendered orphaned outside the quote. Reformatted as a single coherent quote. Reviewer-tooling resilience: - BQAnf / BQAng (integration-tests/...:325/185): added explicit `DaemonSessionSummary` type to two `.find` / `.every` callbacks. Local typecheck infers the type fine via the SDK's source declarations; the reviewer's environment resolves `@qwen-code/sdk` against a possibly-stale `dist/index.d.ts` (per `integration-tests/tsconfig.json` `paths` mapping) and the `s` parameter widens to `any`. Annotation makes both envs happy. Reviewer-only artifacts (no code action): - BQAnb / BQAnc (integration-tests/...:26/30) — same SDK-dist staleness; the imports are correct and resolve fine when `packages/sdk-typescript` has been built. - BQAni (server.test.ts:8 supertest module not found) — Node 20 setup blocker the reviewer noted; resolves cleanly under Node >=22 (our declared engines floor) with `npm install`. * fix(serve,sdk,test): close 7 review threads — fetchTimeoutMs negative + bridge-error context + perm scope contract (#3803) Real fixes: - BQPRo (DaemonClient.ts:136): `fetchTimeoutMs` accepted any number, including negatives that would slip past the `Number.isFinite` check inside `fetchWithTimeout` and fire `setTimeout(-1)` → immediate abort, killing every request before it could complete. Coerce non-positive / non-finite to 0 (the documented disable sentinel) at the constructor so call-site math stays simple. - BQLdO (server.ts:725): `sendBridgeError` now accepts a `ctx` arg `{ route, sessionId }` folded into the stderr log line. Bare `ECONNRESET` / `ENOMEM` traces are no longer unattributable on a busy daemon — operators see `qwen serve: bridge error (POST /session/:id/prompt session=abc-123): ...`. All five route call sites pass context. - BQI-6 (qwen-serve-streaming.test.ts:123): `sseFrames` test helper forwards `opts.signal` into `parseSseStream` so post-connect abort terminates iteration immediately (the parser's own abort- -wired-to-reader.cancel landed earlier; this just plumbs through the test harness). Doc / contract: - BQNqL / BQNqM (httpAcpBridge.ts:692, server.ts:199): `cancelPendingForSession` cancelling all session permissions on client disconnect is intentional under the per-session FIFO + ACP spec — permissions are issued inline DURING an active prompt, the agent awaits them, so the only outstanding permissions at any moment belong to the prompt being cancelled. Cross-client caveat (B's vote 404s when A disconnects mid-A's-prompt) is the right behavior — a vote on a cancelled-prompt's permission wouldn't drive the agent forward. Documented the scope contract + multi-client caveat in `cancelPendingForSession` JSDoc. Already addressed (resolve as ack): - BQI-c (qwen-serve-protocol.md): blockquote was already reformatted in the previous round (`POST /session/:id/cancel` now sits inline on a single quoted line); copilot reviewed an older commit. - BQI-v (DaemonClient.ts): `fetchTimeoutMs` JSDoc was already updated last round to explicitly note `prompt()` is excluded; copilot reviewed the older shape. * fix(serve,test,docs): close 6 review threads — TEST_CLI_PATH + Stage 2 markers + SSE phantom-conn warning (#3803) Real fix: - BQpu6 / BQpvW (integration-tests/cli/...): both qwen-serve test files hardcoded `../../packages/cli/dist/index.js`, while the rest of the integration suite reads `process.env.TEST_CLI_PATH` (set by `globalSetup.ts` to the root `dist/cli.js` bundle). The difference made our tests sensitive to which build step (`build` vs `bundle`) ran last. Now read `TEST_CLI_PATH` first, fall back to per-package dist for direct vitest invocations that bypass globalSetup. Operator-facing doc: - BQsOD (server.ts:497 KNOWN GAP): added an operator warning to `docs/users/qwen-serve.md`'s threat-model section about phantom SSE connections behind NATs that swallow TCP RSTs (kernel keepalive ~2h Linux default → can accumulate to the 256-conn ceiling on `--hostname 0.0.0.0` deployments). Stage 2 will add application-level idle deadline; until then operators on such networks may want to lower `server.keepAliveTimeout` via reverse proxy. Stage 2 maintenance markers (no code change, just visible TODOs): - BQsOA (httpAcpBridge.ts:1247): added `FIXME(stage-2)` on the sync `realpathSync.native` call so the Stage 2 in-process refactor doesn't ship without removing this event-loop-blocking syscall. - BQsOB (server.ts:243): added a SECURITY NOTE on the `...(body as object)` passthrough explaining the spec-defined `_meta` forwarding contract + the rule that an explicit pick is required if any new bridge field starts being trusted by name. Pattern repeats on cancel/model — note covers all four sites. - BQsOF (httpAcpBridge.ts:1041): `FIXME(stage-2)` noting that `setSessionModel` reuses `initTimeoutMs` (default 10s) for the in-flight model swap — conceptually distinct from cold-start init, currently sharing only by coincidence; Stage 2 should split into `modelSwitchTimeoutMs` and remove the no-abort `withTimeout` race-condition once ACP exposes a cancel signal for `unstable_setSessionModel`. * fix(serve): close 4 review threads — unhandled rejection + maxSessions plumbing + 2 docs - httpAcpBridge.sendPrompt: attach .catch(() => {}) to the abort-listener cleanup chain. The chain is `racedPromise.finally (...)` and we never await it; if `racedPromise` rejects, the finally returns a rejected promise that surfaces as an unhandled rejection (Node's default behavior on unhandled rejection is process termination). The route's own catch handles the original rejection — only the cleanup chain needs the swallow. - httpAcpBridge.sendPrompt: FIXME(stage-2) for absolute prompt deadline — buggy agent ignoring cancel + alive channel = slow prompt-promise leak. - server.createServeApp: forward opts.maxSessions when constructing the default bridge. Direct callers (tests, embeds) were silently falling back to DEFAULT_MAX_SESSIONS (20); only the runQwenServe path piped the option through. - docs/users/qwen-serve.md: clarify Host allowlist is loopback-only; non-loopback binds rely on bearer + operator-managed front proxy. * docs(sdk): close 1 review thread — sse.ts MAX_BUF_CHARS docstring lead-line said "bytes" Doc lead-line claimed "Hard cap on accumulated unread bytes" while the implementation enforces the cap via `buf.length` (UTF-16 code units), which the rest of the same docstring already correctly explained. Fix the lead-line so a reader skimming the first sentence isn't misled. The runtime error message and constant name (MAX_BUF_CHARS) already say "code units" — only the docstring lead-line needed alignment. * fix(serve,sdk): close 5 review threads — disconnect/attach race + 3 spec fixes + 1 doc - httpAcpBridge: add SessionEntry.attachCount + new killSession({requireZeroAttaches:true}) opt to fix the BQ9tV race. When client A spawned (attached:false) but disconnected mid-spawn, A's disconnect-reaper (server.ts) could tear down a session that client B had just attached to. spawnOrAttach now bumps attachCount on each attached:true return, and killSession with the new opt bails when attachCount > 0. The check + the eager byId/byWorkspace deletes both run in killSession's synchronous prefix, so the guard is atomic across the await boundary. - server.ts disconnect-reap path now passes requireZeroAttaches:true. - loopbackBinds.ts: lowercase the operator-supplied hostname before Set lookup so --hostname Localhost / LOCALHOST aren't forced to require a token. Aligns boot-time detection with the runtime Host-header check (auth.ts already lowercases). - auth.ts bearer parsing: accept HTAB (0x09) in addition to SP between scheme and credentials per RFC 7230 §3.2.6 BWS. - sdk sse.ts parseFrame: guard against `null` / primitive JSON parses so the AsyncGenerator<DaemonEvent> contract isn't violated by a misbehaving proxy emitting `data: null`. Daemon itself never emits these — defense-in-depth only. - docs/developers/qwen-serve-protocol.md: document the modelServiceId-rejection-on-fresh-session corner case + tell subscribers to pass Last-Event-ID:0 to replay the spawn-time model_switch_failed event from the ring. - 3 new unit tests: BQ9tV positive + negative race paths, BQ9ze parseFrame null guard. * fix(serve): close 4 review threads — 2 critical (NaN cap, stderr buffer) + IPv6 zone-id + deep doc - httpAcpBridge maxSessions normalization (BRApy [Critical] gpt-5.5): NaN / negative values previously fell through `!Number.isFinite(...)` to `Infinity`, silently disabling the daemon's session cap (fail-OPEN on a typo). Now throw TypeError on NaN / negative; explicit 0 and Infinity remain valid "unlimited" sentinels. - httpAcpBridge stderr line buffer (BRAp3 [Critical] gpt-5.5): the per-spawn `buf` accumulating stderr until `\n` had no length cap; a child that wrote a huge line or never emitted a newline could grow daemon memory unboundedly per session. Cap at 64 KiB per line and force-flush with a `[truncated]` marker — keeps the prefix-attributed log line, bounds memory, no content drop. - runQwenServe.formatHostForUrl (BQ-6V copilot): RFC 6874 requires `%` in IPv6 zone IDs (e.g. `fe80::1%lo0`) to be percent-encoded as `%25` in URLs. Now encode on the raw-IPv6 path; already-bracketed input is the operator's responsibility. - /health?deep=1 (BQ-6F copilot): the 503 path is unreachable for the real bridge (counter getters are simple Map-size accessors that don't throw). Reframed in code + protocol doc as INFORMATIONAL observability ("capacity dashboards, not real liveness"); keep the try/catch as defense-in-depth for custom bridge impls. - 2 new unit tests: BRApy NaN/negative throws + 0/Infinity ok; BQ92B Localhost case-insensitive boot. * fix(sdk): close 1 review thread — sse parseFrame tighter shape guard (BREsR followup to BQ9ze) The previous parseFrame guard only rejected null/primitive JSON; arrays and shape-incomplete objects still cast through to DaemonEvent. Tighten to require: non-null non-array object with v === 1 and type: string. Now the generator's static AsyncGenerator<DaemonEvent> type is a genuine runtime guarantee instead of a structural hope. Daemon never emits malformed frames (formatSseFrame always serializes {v: 1, type: string, ...}); guard remains defense-in-depth against misbehaving proxies / alternate implementations. Existing test fixtures already conform to the shape so no other tests needed updating. * fix(sdk): close 1 review thread — fetchWithTimeout keeps timer alive through body consumption (BRN1o) Pre-fix: `fetchWithTimeout` cleared the timer in `finally` the moment the underlying `fetch` resolved. But `fetch` resolves at headers, not at body completion. A daemon or proxy that sent headers and then stalled mid-body left `await res.json()` (and `failOnError`'s `res.text()`) without any deadline — calls to `health()`, `capabilities()`, `createOrAttachSession()`, `listWorkspaceSessions()`, `setSessionModel()`, `cancel()`, `respondToPermission()` could hang indefinitely past `fetchTimeoutMs`. Refactor `fetchWithTimeout<T>` to take an optional `consume(res)` callback whose execution is included in the timer scope. The composed abort signal still flows through to fetch's body stream, so an in-progress `res.json()` rejects cleanly when the timer fires. All JSON-returning routes updated to pass the body-read code as the callback. SSE (subscribeEvents) + prompt are unchanged: they bypass fetchWithTimeout intentionally (long-lived). Regression test: response with a never-emitting body that errors via the composed AbortSignal — pre-fix would hang for 5s+, post-fix rejects within ~80ms (configured timeout). * fix(serve,sdk): close 8 review threads — coalescing race fix + --max-connections + 5 docs/cleanups - httpAcpBridge spawnOrAttach (BRSCi [Critical] DeepSeek): the BQ9tV attachCount fix was incomplete for the in-flight coalescing path. When two callers await the same doSpawn and the second has a modelServiceId, the attach-bump landed AFTER an extra await for applyModelServiceId — leaving a microtask window in which A's killSession sync-prefix would still see attachCount==0 and reap a session B was about to receive. Move the bump to the very first sync step after `await inFlight` (and same in the direct-attach branch) so the bump-before-killSession ordering holds even when the model-switch yields. Test added for the coalescing-race path. - commands/serve + serve/types + runQwenServe (BRQQb): add `--max-connections` flag (default 256), wired through ServeOptions and `server.maxConnections`. Operators with high-concurrency deployments can now tune the listener-level cap without waiting for Stage 2. - commands/serve (BRQQZ): wrap `new Promise<never>(() => {})` in a named `blockForever()` helper so a future maintainer doesn't read the bare expression as a never-resolving-promise bug. - auth.ts (BRQQd): rewrite the comment about HTAB BWS — clarify that the scheme→credentials separator is `1*SP` per RFC 9110 §11.6.2, and HTAB is only accepted in the BWS *after* the SP. `Bearer\t<token>` (pure HTAB) is intentionally rejected. - types.ts + qwen-serve-protocol.md (BRQQf): document `modelServices: []` is always empty in Stage 1 so SDK consumers don't build off it. - qwen-serve.md (BRQQl + BRQQm): add operator note about subscribing to /events BEFORE posting modelServiceId on attach (otherwise the model_switch_failed event is missed). Document the four-layer load cap stack near --max-sessions so operators can size the related knobs together. - sdk index (BRSCv): drop the historical `Daemon`-prefixed type aliases (`DaemonPromptRequest` / `DaemonSubscribeOptions`) for consistency with the other un-prefixed daemon-type exports. SDK is Stage-1-experimental with no shipping consumers. * fix(sdk): close 1 review thread — sse parseFrame must not drop frames whose first line is a comment/retry (BRgq-) Per the EventSource spec, comment lines (`:` prefix) and `retry:` are line-level fields, not frame-level. The previous early return at the top of `parseFrame` dropped the entire frame when its first line was a comment or retry directive — meaning an intermediary that prepends `: keep-alive` or `retry: 5000` to every frame would cause the embedded `data:` payload to be silently lost. Removed the `startsWith` guard. The line-level `data:` collection loop already produces an empty `dataLines` array for pure-comment / pure-retry frames, so the existing `if (dataLines.length === 0) return undefined` branch still skips them — without dropping real events that just happen to be preceded by a comment line. Existing test still pins the standalone-comment / standalone-retry behavior; new test pins the leading-comment + data-line case. * docs(sdk): close 1 review thread — sse MAX_BUF_CHARS comment was overpromising byte-equivalence (BRker) The previous wording suggested "one code unit ≈ one byte" for mostly-ASCII content, then qualified it with mixed BMP / supplementary caveats. Reviewer flagged that JS string.length isn't a reliable byte proxy in either direction — engine string representation (V8 Latin-1 path vs UTF-16) makes the actual memory cost vary in ways the comment didn't capture cleanly. Rewrote to state plainly: cap measures code units, not bytes; intent is "stop runaway non-SSE bodies", not exact memory accounting; byte-precise bounds belong at a front proxy. Threshold and code unchanged — only the comment. * fix(serve): close 7 review threads — atomic write, read-size cap, force-exit on 2nd signal, doc fixes - httpAcpBridge.writeTextFile (BSA0D): atomic write-then-rename via `<path>.<pid>.<ts>.tmp` + `fs.rename`. Closes the SIGKILL-mid-write truncation hole. Tmp file lives in the target's directory so the rename can't cross filesystem boundaries; cleaned up on rename failure. - httpAcpBridge.readTextFile (BSA0E): `fs.stat` pre-check rejects files past 100 MiB so a `{ line: 1, limit: 10 }` against a 500 MB log doesn't allocate 500 MB of RSS just to return 10 lines. - runQwenServe SIGINT/SIGTERM (BSA0K): second signal during drain forces `process.exit(1)` with a stderr message instead of silently no-oping. Standard daemon behavior — `^C^C` works. - commands/serve --hostname help text (BRqFe): now mentions the full loopback set (127.0.0.1, localhost, ::1, [::1]) so IPv6 users aren't misled into thinking ::1 needs a token. - runQwenServe boot-refusal error (BRqFy): same correction — error message now lists all loopback aliases the operator can rebind to. - httpAcpBridge withTimeout doc (BSA0C): explicit Stage 2 follow-up marker for the modelSwitchTimedOut / model_switch_late_success observability gap (already a known limitation). - server.errorPayload (BSA0G): documented the multi-tenant info-leak trade-off (Stage 1 single-user/small-team trust model accepts verbatim ACP error data) and pointed to a Stage 2 --redact-errors follow-up. - 2 new tests: writeTextFile leaves no tmp turd; readTextFile rejects 200 MiB sparse file via the size cap. * fix(sdk): close 1 review thread — sse parseFrame must validate optional `id` (BSP1-) The previous shape guard only validated `v === 1` and `type: string`, leaving `DaemonEvent.id: number | undefined` unchecked. A misbehaving proxy emitting `data: {"id":"1","v":1,"type":"x",...}` would survive the cast and break consumer resume logic — Last-Event-ID resume does numeric comparisons against the monotonic counter, and a string id silently corrupts that math. Reject the frame entirely when `id` is present but not a finite safe integer (`Number.isSafeInteger`). Negative integers and missing-id both still pass; the daemon never emits negative ids in practice but the guard's responsibility is the type-cast contract, not the daemon's id-allocation policy. New test covers: string id, float id, > MAX_SAFE_INTEGER id (all rejected); negative-id, no-id, plain integer (all pass). * docs(serve): Stage 1.5 markers from chiga0 follow-up architecture review (#3889 c4427773706) chiga0's follow-up review explicitly states "None of the findings here block Stage 1. That holds." All 6 findings are Stage 1.5 convergence work for when downstream consumers attach. None require code changes for this PR. Adding inline FIXME(stage-1.5) markers at the natural pivot points so the future refactor has clear breadcrumbs back to the audit comment, instead of Stage 1.5 implementers having to re-discover the convergence story: - types.ts STAGE1_FEATURES → finding 5 (capability registry + extMethod HTTP route). - eventBus.ts EventBus class → finding 2 (lift to packages/event-bus, multi-consumer subscribe). - httpAcpBridge.ts BridgeClient.requestPermission → finding 3 (PermissionMediator + policy plugin point; closes prior chiga0 Risk 2 too). - httpAcpBridge.ts BridgeOptions → findings 1 + 4 (split into AcpChannel + Transport packages; thread FileSystemService through BridgeOptions). No behavior change. Each marker links to the audit comment for traceability. * docs(serve): tighten Stage 1 scope framing + durability + Stage 1.5 must-haves (#3889 c4427875644) chiga0's third review walks three downstream-consumer scenarios (IM bot, mobile companion, IDE extension) against Stage 1's runtime guarantees. The bottom-line concern is framing: the PR body promises "real workloads" but the protocol surface is sized for demo / single-user / never-crashes. Reviewer offers two paths — tighten the framing or add 7 must-haves to Stage 1.5. Author classifies all 10 must-haves as Stage 1.5/2, none as Stage 1 changes. In-scope action for this PR (doc-only, no behavior change): - `docs/users/qwen-serve.md` "Status" block: explicit scope-honesty note — Stage 1 is sized for prototyping clients + local single-user/small-team. Production-grade multi-client / mobile / flaky-network workloads need Stage 1.5+ guarantees. - New "Durability model" section spelling out sessions-are-ephemeral (closes must-have 10): no resume on child crash / daemon restart, ring-overflow on long disconnects, writeTextFile atomic across crash but not across restart. - New "Stage 1.5+ runtime guarantees" section listing the 10 must-haves (blockers 1-3, reliability 4-7, ergonomics 8-10) with a link back to the audit comment for traceability. - `httpAcpBridge.ts` BridgeOptions.sessionScope: FIXME(stage-1.5) marker referencing must-have 1 (per-request override), since this is the most prominent client-facing lock-in risk. No code behavior changes — this is roadmap commentary surfaced into the artifacts where downstream integrators will look (user docs + code pivot points). * fix(serve): close 2 correctness findings from tanzhenxin review Two bugs surfaced in the CHANGES_REQUESTED review: Issue 1 — `--max-connections 0` silently bricks the daemon on Node 22: - Docs say "Set to 0 to disable" and the code did `server.maxConnections = opts.maxConnections ?? 256`, but on Node 22.15.0 setting `server.maxConnections = 0` makes the listener refuse EVERY connection (every fetch → SocketError other side closed). The operator following the documented disable path got a daemon that boots cleanly, logs "listening on …", and then silently rejects health/session/SSE. - Fix: treat 0 / Infinity / non-finite as "leave the property unset" (Node's default = unlimited at this layer). Reviewer verified the Node 22 quirk; verified locally that 100 still binds the cap, 0 and Infinity now both accept connections. Issue 2 — Orphan agent child when both coalesced spawnOrAttach callers disconnect: - The BQ9tV `attachCount` race guard is monotonic. Once B's `spawnOrAttach` bumps it (synchronously, before the route handler can see `!res.writable`), the spawn-owner A's disconnect-reaper sees attachCount > 0 and skips the reap — permanently. If B then also disconnects, neither A nor B's route handler does anything, and the agent child stays alive with no client knowing the id. - Fix: add `bridge.detachClient(sessionId)` that decrements attachCount and reaps iff (attachCount == 0 && subscriberCount == 0). Server's `POST /session` handler calls it on the `!res.writable && session.attached === true` branch (symmetric to the existing spawn-owner-disconnect reap). - Subscriber-count check prevents reaping when a third client C is already on SSE — `detachClient` only fires when the session has no live consumers at all. 2 new tests for issue 1 (max-connections 0 + Infinity still accept connections; 100 still binds as supplied). 2 new tests for issue 2 (detach reaps when alone; detach preserves when SSE subscriber exists). fakeBridge updated with the new method. * fix(serve): close 3 review threads — maxConnections NaN/negative validation + doc fix + close-contract honesty - runQwenServe maxConnections validation (BUF9-): NaN / negative values previously slipped through `cap > 0 && Number.isFinite(cap)` to "leave unset = unlimited", silently fail-OPEN on a CLI typo and weakening the DoS / FD-exhaustion guard. Now throw TypeError upfront (before `app.listen()`) so a malformed cap fails the `runQwenServe` promise instead of escaping as an uncaught exception from the listen callback. - types.ts maxConnections doc (BUb7C): comment said "Node treats 0 as unlimited" but the runtime fix treats 0 as a sentinel and leaves `server.maxConnections` unset (Node 22 quirk). Updated to match. - runQwenServe close()/force-timeout (BUb7h): the 100ms eager `setTimeout(() => finish(), 100)` after `closeAllConnections()` resolved the close promise WITHOUT waiting for `server.close()`'s callback — breaking the "fully closed" contract. Now: force-close just accelerates `server.close` by killing sockets; we still wait on the close callback. A secondary 2s deadline handles the pathological "server.close never fires" case (kernel-stuck socket) with a logged warning, so shutdown stays bounded. * docs(serve): close 8 review threads — code-comment clarity + 3 new Stage 1 known gaps 8 threads in a single Claude Opus 4.7 review pass — 4 duplicate existing chiga0 finding FIXME markers, 1 code-comment clarity, 3 real new doc-worthy Stage 1 known gaps. Code clarity (BUy4U): - The shutdown re-check at doSpawn (`if (shuttingDown) { kill; throw }`) is the LOAD-BEARING correctness contract, not a band-aid as the reviewer framed it. Updated comment to explain: shutdown() runs tear-down in parallel with awaiting `inFlightSpawns` (faster fan-out); the re-check catches spawns whose `newSession` returns AFTER the flag flipped. The alternative — await all inflight to settle BEFORE snapshotting byId — is cleaner to reason about but serializes shutdown by up to `initTimeoutMs` (10s) before any live session starts tearing down. Documented the trade-off. New Stage 1 known gaps in docs/users/qwen-serve.md threat model: - BUy4H (permission auth daemon-global): cross-session vote risk acceptable under Stage 1 single-user / small-team trust model; Stage 1.5 will scope to `POST /session/:id/permission/:requestId` + session-scoped pending map + per-client identity (closes must-have #3 from the downstream review). - BUy4L (10 MB body limit on /prompt): multimodal content past 10 MB hits a cliff; workaround via path reference; Stage 1.5 accepts chunked encoding. - BUy4e (CORS deny blocks `packages/webui`): document explicit deployment options (Electron/Tauri shell, same-origin reverse proxy); Stage 1.5 adds `--allow-origin <pattern>` for opt-in named frontends. Already-marked duplicates (BUy4O, BUy4P, BUy4X, BUy4b) — covered by existing `FIXME(stage-1.5, chiga0 finding N)` / `FIXME(stage-2)` markers from prior rounds. * fix(serve): close 1 review thread — catch --hostname localhost:4170 typo upfront (BU-sh) The previous code path for unbracketed `host:port` typos went: 1. Loopback check fails (`localhost:4170` doesn't match the loopback set after lowercase normalization). 2. Throw "Refusing to bind localhost:4170:0 without a bearer token" — misleading because the operator's real bug is the colon in the hostname, not the missing token. Alternative path if a token IS supplied: hostname flows through to `formatHostForUrl` which sees the `:` and treats as IPv6, wrapping to `[localhost:4170]:port` in the printed URL. Then `app.listen()` fails with ENOTFOUND. Triple-unhelpful failure mode. Fix: catch the typo BEFORE the loopback/token check. Unbracketed input with exactly one `:` is unambiguously the host:port shape — raw IPv6 literals always have ≥2 colons (shortest is `::`), and bracketed IPv6 is handled by its own form check below. Error message suggests the corrected form (`--hostname localhost --port 4170`). * docs(serve): two new Stage 1 scope boundaries (option A + option iii) from LaZzyMan reviews LaZzyMan's two-part review surfaced two structural framing concerns distinct from the chiga0 roadmap items. Neither requires code changes in this PR — they want explicit scope honesty in the user docs: 1. TUI super-client framing (option A from the review): TUI UI is strictly larger than the wire protocol. The ~15 Ink dialogs and `local-jsx` slash commands are local-only; mutating commands like `/approval-mode`, `/memory`, `/mcp`, `/agents`, `/tools`, `/auth`, `/init` change agent behavior but emit no wire event. Documenting remote clients as sharing the agent↔user conversation axis only, NOT the full TUI session state. Implementers told to re-fetch state on reconnect, not rely on incremental events. 2. N parallel sessions cost N× (option iii from the comment): the "1 daemon = 1 session" axiom means N concurrent sessions on one workspace = N daemons with zero resource sharing. Concrete cost table at N=5 (~1.5-2.5 GB RSS, 15 MCP processes, 5× OAuth refresh) so users hit the wall with eyes open. Won't-fix on the main-line Stage 1/1.5/2 roadmap; alternatives (#3803 §21 Path A/B, in-project sidecars) materially change the architecture in ways we won't commit to mid-Stage-1. Peer-agent comparison noted (Cursor / Continue / Claude Code / OpenCode / Gemini CLI all do single-process multi-session). Both choices are intentionally the less-ambitious option; the substantive alternative (option B for taxonomy, option i/ii for N:1) moves to #3803 if real-usage data ever justifies it. * docs(serve): clarify option-A across Mode 1 (headless) vs Mode 2 (TUI co-host) Previous wording treated "TUI is a super-client" as universal truth. But Stage 1's actual shipping configuration is HEADLESS — no TUI shell runs inside the daemon — and in that mode the slash commands listed (`/approval-mode`, `/memory`, `/mcp`, `/agents`, `/tools`, `/auth`, `/init`) simply don't exist. Session state is boot-time- frozen from settings + disk, with only `/model` mutable via HTTP. Restructured the section to split the consequences: - **Mode 1 (headless `qwen serve`, this PR)**: no TUI exists; session state is boot-time-frozen + `model_switched` over HTTP; remote clients see the FULL session state; no drift possible. - **Mode 2 (Stage 1.5 `qwen --serve` co-hosted TUI, future)**: TUI exists alongside remote clients; TUI slash commands mutate session state with no wire events; remote clients see a strict subset; drift possible — re-fetch state on reconnect. The original "super-client" framing applies cleanly only to Mode 2. Mode 1 has no asymmetry — same option-A choice, different consequences. * fix(serve,sdk): close 12 review threads — 6 critical bugs + 6 follow-ups Six critical correctness fixes from the latest review pass: - httpAcpBridge.readTextFile (BX8YO): reject non-regular files via `stats.isFile()`. Char devices / FIFOs / procfs entries report `size: 0` but stream unbounded data; the 100 MiB cap wasn't enough. New `describeStatKind()` helper for human-readable error message ("named pipe (FIFO)" / "character device" / etc.). - httpAcpBridge.writeTextFile (BX8Yp + BX9_h): temp filename now includes randomUUID + exclusive flag `wx`. PID + Date.now() alone collides under concurrent writes within the same ms (sessionScope: 'thread' or coalesced spawns on same workspace). Exclusive mode fails fast on any residual collision instead of silent overwrite. - httpAcpBridge.writeTextFile (BX8Yw): resolve via `fs.realpath` before write-then-rename so symlinks are preserved. Pre-fix rename replaced the symlink with a regular file, leaving the real target unchanged while the write appeared successful. Test added covering both regular targets and symlink targets. - server.parseLastEventId (BX9_I): log a stderr breadcrumb when rejecting a non-empty non-decimal Last-Event-ID header. Pre-fix, clients with a malformed resume header silently resumed from 0 and lost every event buffered during the disconnect with zero evidence in logs. - httpAcpBridge channel.exited (BX9_P): thread {exitCode, signalCode} from the spawn factory through `session_died` event payload. Operators triaging a crash can now read the cause from the SSE frame instead of grepping daemon stderr for the child's pid. - httpAcpBridge spawnOrAttach in-flight coalesce path (BX9_U): defensive re-check that `byId.get()` is still defined after attachCount++ — if a concurrent kill tore down the entry, throw `SessionNotFoundError` instead of returning `attached: true` with a zombie sessionId. Six follow-ups in the same diff: - httpAcpBridge attachCount comment (BVryk + BWGSL): outdated "monotonic, we never decrement" claim — detachClient() now decrements. Comment rewritten to state the actual invariant ("reflects clients whose response was written or is about to be"). - runQwenServe.close() contract (BV-qW): bridge.shutdown errors are now propagated through the close promise (was: silently caught + resolved success). onSignal exits 1 instead of 0 when teardown fails. Server.close error takes precedence; bridge error is the fallback. - sdk sse parseFrame id guard (BX8Y1): require id >= 1 (was: any safe integer including negative). The daemon's Last-Event-ID parser only accepts non-negative decimals and EventBus emits ids starting at 1; negative ids on the wire diverge from resume math. Existing test updated. - runQwenServe server error listener (BX9_i): swap `server.once('error', reject)` for a persistent `server.on('error', log)` after listening. Pre-fix, a post-boot error (EMFILE etc.) was unhandled and crashed the daemon. Tests: +2 for BX8YO (FIFO) and BX8Yw (symlink preserve). Test infrastructure updated for the new `channel.exited` Promise<ExitInfo | undefined> signature. * fix(serve,sdk): close 4 more review threads — frame-scan perf + publish contract + AbortError narrowing + cross-module doc - sse consumeFrames perf (BX9_a): short-circuit the LF path first. In the common LF-only case the CRLF scan was traversing the entire remaining buffer for nothing; now CRLF is only scanned when LF is absent or potentially appears later than a CRLF separator (mixed-encoding edge). - EventBus.publish contract (BX9_p): explicit JSDoc says publish NEVER THROWS (closed-bus returns undefined, subscriber-enqueue errors caught internally). Historical try/catch wrappers in httpAcpBridge.ts are defense-in-depth, not load-bearing; new callers should not add them. - canonicalizeWorkspace doc (BX9_q): elevate the cross-module contract from "undocumented" to explicit — config.ts / settings.ts / sandbox.ts / this file all canonicalize the same way for sessionScope: 'single' re-attach. A divergence silently forks sessions per spelling. The Stage 1.5 @qwen-code/acp-bridge lift (chiga0 finding 1) is the natural place to extract a shared primitive; until then, any change to those modules needs a matching change here. - POST /session/:id/prompt AbortError swallow (BX9_k): narrow the swallow to only fire when `abort.signal.aborted` is true. The previous blanket `err.name === 'AbortError'` would also silently drop AbortErrors raised internally by the bridge (e.g. child process aborting mid-prompt), leaving the client with no response and no log trace. * docs(serve): correct N:1 framing — qwen-code's ACP agent natively supports multi-session Maintainer feedback (verified against the code): the ACP agent in packages/cli/src/acp-integration/acpAgent.ts:194 has `private sessions: Map<string, Session>` — one `qwen --acp` child natively hosts multiple sessions, and yiliang114's VSCode plugin already uses this pattern. The earlier "qwen-code is the only entry treating no multi-session resource sharing as a feature" framing (from the LaZzyMan reply + docs) was wrong. Stage 1 bridge in this PR doesn't yet leverage that capability — it spawns one `qwen --acp` child per session for simplicity (easier debugging, no cross-session interference during initial stabilization). That's a bridge-side design choice, not an ACP limitation. Revised docs/users/qwen-serve.md: - "N parallel sessions cost N×" section now distinguishes Stage 1 bridge (current N× cost) from Stage 1.5 bridge (multi-session per child, ~1/5th the cost at N=5). Cost table extended with the Stage 1.5 column. No more "won't fix on main-line roadmap" framing — the fix is a bridge refactor that pairs naturally with chiga0 finding 1 (`@qwen-code/acp-bridge` package lift), NOT the #3803 §21 Path A/B/C intra-daemon multi-session workstream (qwen-code already does that at the agent layer). - Status block's "Scope honesty" note: removed the implicit permanent-cost framing; replaced with explicit "Stage 1 bridge pays N×; Stage 1.5 refactor closes the gap" pointer. - Peer-agent comparison rewritten: qwen-code's *agent* matches Cursor / Continue / Claude Code / OpenCode / Gemini CLI on single-process multi-session; the bridge is the artifact. `httpAcpBridge.ts:doSpawn`: inline `FIXME(stage-1.5)` marker explaining the refactor (keep one child per workspace, call `connection.newSession()` multiple times on the same channel), with the link to `acpAgent.ts:194` so a future maintainer doesn't re-derive the discovery. * feat(serve): Stage 1 bridge now multiplexes sessions on one qwen --acp child per workspace Per LaZzyMan / tanzhenxin reviews + maintainer feedback verified against `packages/cli/src/acp-integration/acpAgent.ts:194` (the agent's `private sessions: Map<string, Session>`): qwen-code's ACP agent natively supports multi-session in one child process. The Stage 1 bridge previously spawned one child per session for simplicity, paying N× memory / OAuth / file-cache cost. Now refactored to leverage the agent's existing multi-session capability — one `qwen --acp` child per workspace, N sessions share it via `connection.newSession({cwd, mcpServers})`. Cost at N=5 sessions on same workspace: - Before: 300-500 MB RSS (5 children), 5× OAuth refresh, 5× file cache, 5× CLAUDE.md parse, 5× cold start - After: 60-100 MB RSS (one child), one OAuth path, shared FileReadCache, parsed once, <200ms cold start after first session Architecture changes: - New `ChannelInfo` type holds the shared channel + connection + BridgeClient + the set of session ids multiplexing on it. - New `byWorkspaceChannel: Map<workspace, ChannelInfo>` + new `inFlightChannelSpawns` coalesce-map for concurrent channel creation. - New `getOrCreateChannel(workspaceKey)` helper: reuse existing channel or spawn one (with `initialize` happening exactly once per channel, not once per session). Coalesced via `inFlightChannelSpawns` so two parallel callers don't both spawn. - `doSpawn` now calls `getOrCreateChannel` + `connection.newSession` separately (was: spawn+initialize+newSession together per session). - `BridgeClient` updated: `resolveEntry(sessionId?)` dispatches by the sessionId ACP carries in each request — one BridgeClient now serves all sessions on its channel. `sessionUpdate`, `requestPermission`, etc. all pass `params.sessionId`. - `channel.exited` cleanup moved into `getOrCreateChannel` and now tears down ALL sessions on the channel (not one). Each session gets its own `session_died` event so SSE subscribers learn the bad news on their own stream. - `killSession` now removes session from `channelInfo.sessionIds` and kills the channel ONLY when its sessionIds set drops to zero. Other sessions on the same channel keep running. - `shutdown` tears down channels (the deduplicated set) and awaits both inFlightSpawns and inFlightChannelSpawns. Cross-workspace channel sharing intentionally NOT done — `acpAgent.ts: 601 (this.settings = loadSettings(cwd))` reloads settings on each newSession call with a different cwd, so different workspaces in one child would step on each other. One channel per workspace is the safe scope. MCP server children stay per-session for now (each session can have different mcpServers config). Stage 1.5 follow-up: refcount MCP children by (workspace, config-hash) so identical configs share. Tests: - Updated `spawns fresh per call under sessionScope:thread` → now expects `handles.length === 1` (channel reused) but `sessionCount === 2` (distinct sessions). - New: `Stage 1.5 multi-session: N sessions on same workspace share ONE channel` (5 sessions, 1 factoryCalls). - New: `Stage 1.5: killSession on one of N sessions does NOT kill the shared channel` (kill 2 of 3, channel still alive; kill 3rd, channel killed). - New: `Stage 1.5: channel.exited tears down ALL multiplexed sessions` (each gets its own session_died). - FakeAgent.newSession suffixes call-count so multiple newSession calls on the same channel return distinct ids (matches real ACP behavior). Docs: - `docs/users/qwen-serve.md` N:1 section rewritten — no longer "Stage 1 pays N×, Stage 1.5 fixes". Cost table reflects current shared-channel architecture; MCP refcount called out as the one remaining Stage 1.5 follow-up; "1 daemon = 1 session" framing removed from related sections. * fix(serve,sdk): close 12 review threads — 6 critical bugs + 6 follow-ups Critical fixes: - server.ts safeBody() helper (BZ9uv/va/vs/wD + Bd10m + Bd1zz): prototype-pollution sanitization at the body-spread boundary. `__proto__` / `constructor` / `prototype` keys are stripped and the result is an Object.create(null) target. Replaces 5 sites of copy-pasted `typeof req.body === 'object'...` preamble + makes the `...(body as object)` spread sites safe. - httpAcpBridge requestPermission (Bd1yh): per-request wall-clock deadline (default 5 min, configurable via `BridgeOptions.permissionResponseTimeoutMs`). Without this, an agent calling requestPermission with no SSE subscriber connected would hang the per-session FIFO forever. After deadline, resolve as cancelled + log stderr warning. - httpAcpBridge requestPermission (Bd1z5): per-session pending permissions cap (default 64, configurable via `BridgeOptions.maxPendingPermissionsPerSession`). New requests past the cap resolve as cancelled with stderr warning. Prevents a chatty agent from growing pendingPermissions unboundedly. - runQwenServe onSignal double-signal force-exit (Bd1y6): new `bridge.killAllSync()` + `AcpChannel.killSync()` method synchronously SIGKILLs every live qwen --acp child BEFORE `process.exit(1)`. Previously double-Ctrl+C bypassed the async bridge.shutdown() and left children running as orphans. - server.ts SSE subscriber-limit response (Bd1zJ): 429 + Retry-After instead of 200 + stream_error frame. EventSource treats 4xx as terminal (no auto-reconnect); the previous 200+close-stream triggered EventSource's reconnect loop, amplifying the load the limit existed to prevent. - doSpawn ghost sessionId guard (Bd1zc): re-check byId.has() after applyModelServiceId(). The model-switch yields and can race channel.exited; without this, caller got HTTP 200 with a sessionId that 404s on every subsequent request. Follow-ups in the same diff: - sse.ts consumeFrames CRLF scan comment (BcRh_): the comment claimed the CRLF scan was bounded to `[cursor, lf)`, but Node's `indexOf` has no upper bound. Rewrote to describe what the code actually does (scan full remainder; only USE the result if it falls before `lf`). - sse.ts SseFramingError export (Bd10T): typed error class for framing-level failures so SDK consumers can distinguish "upstream isn't SSE" from generic network errors via instanceof check. Re-exported from @qwen-code/sdk. - protocol doc /health auth (Bctum): document the loopback exemption — `/health` doesn't require Authorization on loopback binds even when a token is configured. Matches `createServeApp`'s registration order. Bd1xz (cross-session permission escalation) acknowledged as duplicate of BUy4H — already documented as a known Stage 1 gap under the single-user / small-team trust model; fix is Stage 1.5 must-have #3 (per-client identity + per-session permission scope). Tests: - New: prototype-pollution test verifies `__proto__` spread doesn't pollute `Object.prototype`. - All 70 server + 55 bridge + 16 daemon-sse + 60 DaemonClient tests pass (203 total). `killSync()` stubbed on every inline test channel fake; fake bridge has `killAllSync()`. * fix(sdk): close 2 review threads — consumeFrames CRLF scan now actually bounded (BeFHR + BeFId) Previous attempt at the BX9_a perf optimization left the CRLF scan running over the full remainder of `buf` on every loop iteration where an LF separator existed — only the LF-not-found fallback path was actually bounded. Comments claimed the CRLF scan was restricted to `[cursor, lf)` or "only fires when needed", but Node's `String.indexOf` doesn't accept an end index. Bound the scan via a `buf.slice(cursor, lf)` window before `indexOf` so the assertion is now true: in the common LF-only case we pay one full scan (for LF) plus one bounded scan over the matched frame's bytes (small). * fix(serve): close 3 review threads + Windows test skip — dangling symlink, no-sessionId throw - httpAcpBridge.writeTextFile BfFvO: dangling-symlink case. `fs.realpath` throws ENOENT for a symlink whose target doesn't exist, and the blanket catch silently fell back to writing through the symlink itself — `rename(tmp, params.path)` then replaced the symlink with a regular file, exactly the bug BX8Yw was supposed to fix. Use `fs.readlink` to disambiguate "truly non-existent" from "dangling symlink"; resolve the dangling target manually and write through to it so the symlink stays a symlink. Regression test added. - httpAcpBridge BridgeClient resolveEntry BfFut: defensive throw on no-sessionId ACP call against a multi-session channel. ACP today carries sessionId on every per-session call, but if a future no-sessionId call lands, silently dropping it on a multi-session channel would be invisible. - httpAcpBridge.test.ts BX8YO Windows skip: hard-skip via `process.platform === 'win32'`. Git-Bash etc. ship a `mkfifo` binary that degenerates on Windows (creates a regular file or silently no-ops), making the assertion match the wrong error shape. Linux + macOS coverage is sufficient for a platform- agnostic `!stats.isFile()` check. BfFvW (CRLF scan comment) was already addressed in 0a4146a02 — the reviewer's diff was against the pre-fix version. * fix(serve): close 6 review threads — 4 critical bugs + 2 doc updates Critical fixes: - httpAcpBridge.doSpawn newSession-failure cleanup (BkwQA): if `connection.newSession()` throws on a freshly-created channel whose sessionIds set is empty, tear the channel down rather than leaking the empty `qwen --acp` child in `byWorkspaceChannel` (invisible to `sessionCount` / `maxSessions`). Channels with other live sessions still survive — only the truly-empty case reaps. - httpAcpBridge.detachClient + killSession tombstone (BkwQP): detachClient no longer reaps live sessions. Scenario: A spawns (attached: false, hasn't opened SSE yet), B attaches (attachCount: 1), B disconnects → previous code reaped A's still-valid session. New behavior: * killSession({ requireZeroAttaches: true }) sets `entry.spawnOwnerWantedKill = true` when it bails on attachCount > 0 (instead of just returning). * detachClient ONLY decrements attachCount. It completes the deferred reap only when (spawnOwnerWantedKill && attachCount === 0 && subscriberCount === 0). * Both-disconnected case still works (reap completes via B's detachClient seeing the tombstone). Spawn-owner-alive case no longer reaps. Existing tanzhenxin-issue-2 test rewritten; new test pins the spawn-owner-alive case. - httpAcpBridge.writeTextFile mode preservation (BkwQW): stat the target before writing; if it exists, chmod the tmp file to the preserved mode (and chown owner/group — best-effort, EPERM ignored for non-root). Previously a 0600 secret/config edit would downgrade to umask-default 0644, exposing contents to other local users. - bridge.respondToPermission option-ID validation (BkwQI): new `InvalidPermissionOptionError` thrown when the voter's `optionId` isn't in the set of options the agent originally offered in the `permission_request` event. PendingPermission now carries `allowedOptionIds`. Server route catches the error → 400 (vs. 404 for unknown requestId). Prevents authenticated clients from forging hidden outcomes like `ProceedAlways*` when the prompt's `hideAlwaysAllow` policy intentionally suppressed them. Doc fixes: - httpAcpBridge top-of-file (BkdCg) + types.ts ServeMode (BkdC8): rewrite the "each session spawns its own qwen --acp child" framing to match the actual Stage 1.5 multi-session-per-channel architecture (one child per workspace, sessions multiplex via `connection.newSession()`). * fix(serve): close 4 review threads — close write-mode race + 2 missing tests + 1 doc - writeTextFile mode-bits race (Blehd): the BkwQW fix preserved mode via `chmod` AFTER `fs.writeFile`, leaving a brief window where a `0600` secret-edit was readable at the directory's umask default (commonly `0644`). Now pass `mode` to writeFile directly so the file is CREATED with the preserved mode atomically via the `open(O_CREAT, mode)` syscall. The post-write `chmod` remains as belt-and-suspenders against a tight operator umask (POSIX `mode & ~umask` could drop bits we wanted preserved). - httpAcpBridge.test.ts: new bridge-level test for the BkwQI `InvalidPermissionOptionError` path (Blehk). Forge a vote with an `optionId` not in the agent-offered set; assert the throw AND that the pending permission survives so a valid vote can still resolve it. - server.test.ts: new route-level test for the BkwQI 400 mapping (Blehl). Fake bridge throws `InvalidPermissionOptionError`; assert response is 400 with `code: 'invalid_option_id'`, `requestId`, and `optionId` in the body. - commands/serve --http-bridge help text (Bk59I): updated to reflect Stage 1.5 multi-session — "one `qwen --acp` child per workspace, with multiple sessions multiplexed via the agent's native `newSession()`" (was: "per-session child"). * fix(sdk): close 1 review thread — parseSseStream abort path catches body-read rejection (BlqF_) Some fetch impls (undici on abort) reject the in-flight `reader.read()` with an AbortError after `reader.cancel()` fires. Pre-fix that rejection bubbled to the consumer's `for await`, contradicting the "abort cancels cleanly" public contract — code that called `controller.abort()` to wind a subscription down saw an unexpected throw on the next iteration. Wrap `reader.read()` in try/catch: - if `signal?.aborted` is true → treat the rejection as clean completion (return from the generator) - otherwise re-throw, so real upstream failures (network drop, unexpected close, malformed body) still reach the consumer Two regression tests pin the guard's scope: signal-aborted mid-stream returns cleanly with the frames received so far; a non-abort `streamController.error(...)` still bubbles via `rejects.toThrow`. * fix(serve): close 1 review thread — eventBus eviction detaches abort listener (BmJT1) Pre-fix: `publish()`'s eviction path deleted the sub from `this.subs` but never invoked `dispose()`, leaving the AbortSignal abort-listener registered in `subscribe()` attached. Because the consumer is by definition stalled (that's what caused the overflow), `next()` / `return()` never fire to detach the listener through the iterator path. Closures over the queue + sub stayed live until the AbortSignal itself went out of scope. Under attack (thousands of opened-then-stalled SSE clients), this amplified into significant heap retention. Fix: store `dispose` on `InternalSub` and invoke `sub.dispose()` from the eviction path. The same closure used by the abort listener / the iterator's `next()`/`return()` cleanup now runs through the eviction path too — idempotent through `disposed` so a post-eviction abort or iterator-return is still safe. Regression test pins the post-eviction abort + publish path producing zero side effects. * fix(serve): close 1 review thread — restore double-Ctrl+C force-kill broken by multi-session refactor (BkUyD) The Bd1y6 design promised a second SIGINT/SIGTERM during graceful drain synchronously SIGKILLs every live agent child via `bridge.killAllSync()` before `process.exit(1)` — the operator- visible "kill it now" path for a wedged child ignoring SIGTERM. The Stage 1.5 multi-session refactor (commit 6a170ef8) inadvertently broke this. `shutdown()` snapshots `byWorkspaceChannel` then CLEARS the map BEFORE awaiting the per-child SIGTERM-grace kills (up to ~10s each). If the operator double-taps mid-window, `killAllSync()` snapshotted from the now-empty `byWorkspaceChannel.values()` and silently no-op'd — the for-loop iterated nothing, `process.exit(1)` fired, and any child still inside its SIGTERM grace window was left orphaned with dangling pipes. Exactly the scenario the force-kill path was added to handle. Fix: introduce a separate `liveChannels: Set<ChannelInfo>` as the source of truth for "channels with potentially-alive child processes". Added in `getOrCreateChannel` alongside `byWorkspaceChannel.set(...)`; removed only when `channel.exited` fires (the OS-level "really dead" signal). `killAllSync()` now iterates `liveChannels`, so a mid-shutdown second signal still sees every still-alive child regardless of where the graceful drain currently is. Other paths (`killSession` last-session reap, `channel.exited` crash handler) automatically remove via the same exit-handler hook. Regression test: - Builds two sessions on different workspaces - Replaces each channel's `kill()` with a never-resolving Promise (simulating stuck SIGTERM grace) - Calls `bridge.shutdown()` to enter mid-drain state - Yields twice so shutdown's sync prefix runs (clears byWorkspaceChannel, starts the never-resolving awaits) - Calls `bridge.killAllSync()` — pre-fix this saw an empty `byWorkspaceChannel` and the spy array would have been empty; post-fix both channels' `killSync` is invoked. (tanzhenxin's other observation — channels-package duplicate ACP bridge — is the same architectural concern as chiga0 finding 1+5, already tracked under existing FIXME(stage-1.5) markers. No code change in this commit for that.)	2026-05-13 14:47:47 +08:00
qqqys	fd53527aad	feat(cli): support batch deletion of sessions in /delete (#3733) ... * feat(cli): support batch deletion of sessions in /delete Closes #3706 Add multi-select mode to the session picker so /delete can remove multiple sessions at once. Space toggles a checkbox on the cursor item; Enter commits the checked set, falling back to single-select when nothing is checked. The current active session is rendered disabled with a "current — cannot delete" hint and is also stripped defensively before the service call. Core gains a `removeSessions(ids)` batch API that returns `{ removed, notFound, errors }` so the CLI can surface partial failures with a single toast. Co-Authored-By: Qwen-Coder <noreply@alibabacloud.com> * fix(cli): address /delete batch-delete review comments - useSessionPicker: when checked items are all hidden by the branch filter, do not silently fall through to single-deleting the cursor row (data-loss path); stay in multi-select mode instead. - SessionPicker footer: count only the checked-and-visible-and-committable rows so "N selected" matches what Enter would actually delete. - useDeleteCommand: partial-failure toast switches to type=error and surfaces failing session ids (truncated, capped at 3 with overflow) plus the first underlying error message, instead of just an aggregate count masquerading as info. - Docs: fix Tab→Space JSDoc / inline-comment drift across the picker surface (Space is the actual binding). Co-Authored-By: Qwen-Coder <noreply@qwenlm.com> * docs(cli): clarify disabledIds is multi-select-only on session picker Reviewer flagged that disabledIds is silently inert in single-select mode because both its visual dim and Space no-op gate on enableMultiSelect. Spell that out on both prop JSDocs and point future callers at filtering initialSessions for single-select use cases. Co-Authored-By: Qwen-Coder <noreply@alibabacloud.com> * fix(cli): address /delete batch-delete review feedback (round 2) - useSessionPicker: throw when enableMultiSelect is on without onConfirmMulti (footer would otherwise read "N selected" while Enter silently fell through to single-select on the cursor row) - useSessionPicker: single-select Enter fallback now respects disabledIdSet so a stray Enter on the dimmed active-session row no longer closes the dialog and bounces back with an error - useDeleteCommand: stop swallowing the outer catch — log + surface the underlying error message so on-call has something to grep - useDeleteCommand: full-failure branch now mirrors the partial- failure branch (failing ids + first error reason) instead of a generic "Failed to delete sessions." - useDeleteCommand: emit a "Deleting N session(s)..." progress toast before awaiting removeSessions so slow filesystems don't leave the user staring at a closed dialog - sessionService: JSDoc {@link removed}=false → {@link notFound} Tests: regression for the disabled-row single-select fallback, two invariant-throw tests for the picker, a pre-await progress toast test, and align the StandaloneSessionPicker branch-filter tests with main's Ctrl+B-only binding (plain 'B' silently entered search mode after the merge, masking the assertion). Co-Authored-By: Qwen-Coder <noreply@qwen.ai> * test(cli): drop wait-based multi-select picker tests, cover at hook level The Multi-select describe block in StandaloneSessionPicker.test.tsx was 7 ink-rendering tests that all relied on `await wait(N)` to sync with stdin events — the same flaky shape #3978 already purged from the search suite. CI flaked on them once and they're gone for good. Critical invariants are re-asserted at hook level in useSessionPicker.test.tsx (toggleChecked add/remove + no-op on disabled ids), which exercise pure state without keypress sim. Footer-rendering and keypress-driven flows are intentionally left to manual verification rather than carried as wait-based integration tests. Co-Authored-By: Qwen-Coder <noreply@qwen.ai> * test(cli): cover batch delete keyboard and failure paths * fix(cli): address /delete batch-delete review feedback (round 3) - useSessionPicker: Enter now commits *every* checked id (minus disabled), not just the filtered intersection. Filter is a navigation aid; gating the commit on it would silently drop checks the user explicitly made (check A-E, type a query matching only C-E, lose A and B). Order by sessionState.sessions so the receiver sees display order even for filter-hidden items. - SessionPicker: footer count switches from visibleCheckedCount to committableCheckedCount (all checkedIds minus disabled), so it can no longer say "0 selected" while Enter is about to delete three hidden checks. - useDeleteCommand: hoist sampleIds/overflow/firstError/reason above the three-way branch so partial- and full-failure paths can't drift out of sync on a future tweak. - useDeleteCommand: in-flight ref guard wrapped in try/finally drops re-entrant /delete invocations (closeDeleteDialog runs synchronously, so without this the user can re-open /delete and queue an overlapping batch). Guard releases on early return too, otherwise a "only current selected" rejection would lock out the rest of the session. - useDeleteCommand: surface "Current active session skipped." info toast when the picker forwarded the active session, otherwise the progress toast lies about the count. Tests: - useDeleteCommand: full-failure branch (removed=0), re-entrant drop, guard-released-on-early-return, stripped-current info toast - useSessionPicker: hook-level keypress suite covering Space toggle, Space-disabled no-op, Enter→onConfirmMulti, Enter→onSelect fallback, Enter-disabled no-op, Enter commits hidden checks, Enter refuses when every check is disabled.

Shaojin Wen	d07daa3e69	fix(cli): auto-restore prompt and preserve queue on cancel (#4023) ... * fix(cli): auto-restore prompt and preserve queue on cancel; align with Claude Code When a user pressed ESC immediately after submitting a prompt (before the model produced any meaningful output), qwen-code left the cancelled prompt stranded in the transcript and in cross-session ↑-history. Cancelling during tool execution also silently dropped any queued follow-up input. Mirror Claude Code's auto-restore-on-interrupt: - Drain the queue back into the input buffer on EVERY cancel path, including tool-execution cancels (replaces the unconditional clearQueue() that motivated #3204 with a non-destructive pop). - When the user cancels with no draft text, no queued input, and no meaningful pending/committed assistant content, truncate the user item and trailing INFO from history and pull the prompt text back into the input box for editing. - Add Logger.removeLastUserMessage so the disk-backed cross-session ↑-history (getPreviousUserMessages) is also cleaned on cancel. The "meaningful content" check matches Claude Code's messagesAfterAreOnlySynthetic: gemini text and tool runs are meaningful; info/error/warning/retry/notification/tool_use_summary/thoughts are synthetic. truncateToItem uses functional setState so it batches with the INFO addItem from cancelOngoingRequest in the same render pass — no flicker. Tests cover all five guard branches and the logger undo across normal, no-op, one-shot, MODEL_SWITCH-interleaved, disk-rotation, and uninitialized cases. * fix(core): clear lastLoggedUserEntry on logMessage write failure Without this, a transient writeFile error during a USER logMessage left the undo tracker pointing at the previous successful entry. A subsequent removeLastUserMessage (e.g., from auto-restore on cancel) would then silently delete an unrelated earlier row from disk-backed history. Add a regression test that mocks a writeFile rejection and asserts the tracker is null and the prior entry survives. Reported in PR review. * fix(cli, core): share Logger across AppContainer/useGeminiStream and serialize writes PR-review follow-up addressing two issues in the cancel-undo path. 1. Logger instance mismatch (Critical): `useGeminiStream` and `AppContainer` each called `useLogger()`, which instantiates a fresh `Logger` per call. `lastLoggedUserEntry` lives on the instance, so the undo invoked from `AppContainer` was always a no-op — the cancelled prompt still surfaced via cross-session `getPreviousUserMessages`. Move the `useLogger` ownership to `AppContainer` and pass the same instance into `useGeminiStream` via a new optional `logger` parameter. 2. Logger write ordering: Both `logMessage` and `removeLastUserMessage` do read → splice/append → writeFile without a lock. A fast cancel-then-resubmit could let `removeLast` clobber a just-appended new entry. Add a per-instance `serialize()` helper (a Promise-chained write queue) and route both mutating ops through it. Reset the queue on `close()`. New regression test fires removeLast and a fresh logMessage in parallel and asserts the resubmitted entry survives. 3. Stale React-state race in cancel guard (Suggestion): The auto-restore guard read `pendingGeminiHistoryItems` from React state, which can lag a stream chunk that just set `pendingHistoryItemRef.current`. Snapshot the pending item at the start of `cancelOngoingRequest` and pass it through the new `onCancelSubmit({ pendingItem })` info parameter. The guard combines it with the React-state items so any meaningful in-flight content blocks auto-restore even before re-render. New test covers the case where pendingHistoryItems is empty but info.pendingItem carries `gemini_content`. All touched-area suites pass: 64 cli AppContainer, 9 historyUtils, 85 useGeminiStream, 46 core logger. * fix(cli): unbreak build after import-merge regression and tighten cancel-handler test types The pre-commit eslint --fix on the previous commit collapsed the two consecutive `import { ... } from '@qwen-code/qwen-code-core'` blocks in useGeminiStream.ts into a single statement, but kept the `import type` modifier from the first block — silently turning every runtime symbol (SendMessageType, MessageSenderType, GitService, ApprovalMode, …) into type-only imports. tsc rejected with TS2206 + a wave of TS1361 errors that only surfaced on CI. Restore the two separate imports: pure-type symbols (Logger included) in `import type { ... }`, runtime symbols in plain `import { ... }`. Also: the AppContainer cancel-handler tests captured `onCancelSubmit` as `() => void`, but the hook signature now takes an optional info arg. Widen the captured-callback type so passing `{ pendingItem }` typechecks (TS2554 on line 1053). * fix(cli, core): tighten cancel-undo robustness from PR review batch 3 Four follow-ups from a /review pass on the auto-restore-on-cancel path. * logger.ts — only invalidate `lastLoggedUserEntry` when the failed write was itself a USER attempt. A failed non-USER write (MODEL_SWITCH on a transient disk error, etc.) doesn't change which row was the most recent user prompt, so the prior undo target is still valid. Without this, MODEL_SWITCH disk hiccups silently disabled cancel-undo. * useGeminiStream.ts — wrap `onCancelSubmit` in try/finally so a throw in AppContainer's cancel handler can't strand the stream in Responding (the UI would lock — Esc would no-op until process restart). `setIsResponding(false)` and `setShellInputFocused(false)` always run. * useGeminiStream.ts — also document the three-way coupling between the INFO `addItem` here and AppContainer's auto-restore guard: the guard reads `historyRef.current` which doesn't yet contain this INFO (React batches), and the guard's correctness depends on the items added here staying synthetic. * historyUtils.ts — make `isSyntheticHistoryItem` exhaustive over the 35-member `HistoryItemWithoutId` union. Every case is explicit; the default branch carries a `_exhaustive: never` so adding a new HistoryItem variant without classifying it triggers a compile-time error rather than silently disabling auto-restore. Runtime fallback is "meaningful" (safe — bail rather than wipe content). Tests: +1 logger case (non-USER failure preserves the USER tracker), +1 useGeminiStream case (throwing handler still flushes Responding). All touched suites pass: 47 logger, 9 historyUtils, 86 useGeminiStream, 64 AppContainer. * docs(core): clarify Logger writeQueue scope (log-history only, not checkpoints) Reword the comment above `writeQueue` and the `serialize()` JSDoc to state explicitly that the queue only serializes log-history mutations (`logMessage` / `removeLastUserMessage`). Checkpoint ops (saveCheckpoint / deleteCheckpoint / loadCheckpoint) touch separate files and intentionally don't share this queue, so the previous "every disk-mutating op chains here" wording overstated the guarantee. * fix(cli): flush buffered stream events before snapshotting pendingItem on cancel Stream content/thought events are throttled into a per-turn `bufferedEvents` array; only when `flushBufferedStreamEvents` runs do they reach `pendingHistoryItemRef.current`. Snapshotting BEFORE the flush meant cancels that fired inside the throttle window (60ms) saw a null `pendingItem` even when meaningful text was sitting in the buffer. AppContainer's auto-restore guard then read null, decided "model produced nothing", and called `truncateToItem` — which silently wiped the very content that the subsequent `addItem(pendingHistoryItemRef.current)` had just committed. Move the snapshot to AFTER the flush so it sees the same value as the addItem call directly below it. Regression test: yields a content event and cancels without advancing fake timers, asserts `info.pendingItem` carries the buffered "partial response" text rather than null. * fix(core): apply Logger.removeLastUserMessage in-memory removal synchronously AppContainer's `userMessages` effect calls `getPreviousUserMessages()` on the same render that history truncation fires (it depends on `historyManager.history`). The previous implementation only updated `this.logs` after `await fs.writeFile(...)` settled, so the effect read stale logs and ↑-history surfaced the cancelled prompt until some unrelated future history change re-ran the effect. Move the cache filter ahead of the serialize queue so consumers see the removal immediately. The async serialize op continues to read, splice, and write disk, then re-syncs `this.logs` from disk on success or rotation. Regression test fires removeLast without awaiting, then asserts the very next `getPreviousUserMessages()` returns [] (no cancelled prompt), and that the background promise still resolves to true. * docs(core, cli): clarify removeLastUserMessage contract; observability for cancel-undo * logger.ts — extend the JSDoc on `removeLastUserMessage` to spell out the two-phase semantics (sync optimistic in-memory removal + async serialized disk reconciliation), and explicitly document that the boolean return value reflects the *disk* outcome while the in-memory cache is updated unconditionally. Also explain why disk failures are NOT rolled back: rolling back would resurrect the cancelled prompt in ↑-history, which is worse UX than a temporary cache/disk divergence (which converges on next op or on `initialize()` of the next session). * AppContainer.tsx — wrap the fire-and-forget `logger.removeLastUserMessage()` in `.catch(debugLogger.debug)`. The Logger's internal try/catches mean the Promise should never reject today, but a future code-path change shouldn't surface as an UnhandledPromiseRejection — and a debug-level log is the right observability hook for "cancel succeeded in UI but disk-undo failed silently". * fix(core,cli): #4023 review wave — logger atomicity + observable undo failure 3 #4023 review threads addressed: - core/logger.ts: `removeLastUserMessage` now ROLLS BACK the optimistic in-memory removal when the disk read or write fails. Previously the JSDoc/return contract was violated: the method returned `false` on failure but `this.logs` already showed the entry removed — callers (AppContainer's `userMessages` effect) saw the inconsistency and the cancelled prompt vanished from ↑-history despite the disk still carrying it. The rollback re-inserts the target at its original index when no concurrent mutation took its place, and restores `lastLoggedUserEntry` so a follow-up retry has a target. Regression test pinned: spy on fs.writeFile to throw, assert `removed === false` AND getPreviousUserMessages() still surfaces the entry. - cli/AppContainer.tsx: `void logger?.removeLastUserMessage()` no longer silently swallows failures. Added `.catch` that routes through `debugLogger.debug` so a disk-write failure leaves a diagnostic trail; without it the cancelled prompt would resurrect next session via ↑-history with no observability into why. - cli/historyUtils.ts: `gemini_thought` / `gemini_thought_content` classification reaffirmed as SYNTHETIC with explicit JSDoc on WHY (Claude Code parity + auto-restore is most valuable in the cancel-during-thinking case which is exactly the case where thoughts have appeared but no committed `gemini_content`). Future readers won't re-litigate the classification by accident. Tests: 49/49 logger.test.ts pass; tsc + ESLint clean. * docs(core): align removeLastUserMessage JSDoc with rollback-on-failure behaviour The previous commit added a rollback path to `removeLastUserMessage` (re-insert the optimistically-removed entry and restore `lastLoggedUserEntry` when the disk read or write throws), but the JSDoc still said the in-memory removal is "intentionally NOT rolled back" — a copy-paste leftover from the earlier design that picked optimistic-and-diverge. Rewrite the failure-handling paragraph and `@returns` line to describe the rollback contract instead. No code change. * fix(cli, core): scope auto-restore to the cancelled turn + tighten typings/tests Three follow-ups from PR #4023 review batch 5. * cli — `CancelSubmitInfo` gains `lastTurnUserItem` carrying the user prompt text that THIS turn's `prepareQueryForGemini` added (or `null` for paths that don't push a user history item: Cron / Notification / slash `submit_prompt`). `cancelOngoingRequest` snapshots `lastTurnUserItemRef.current` and ships it through. The AppContainer auto-restore guard now requires `info.lastTurnUserItem` to be present AND match the candidate user item's text before truncating/rewinding — closing the case where an older user item happens to be followed by only-synthetic trailing content and the current cancelled turn never owned a user item to begin with. Two new regression tests pin both halves: cancel of a non-USER turn bails despite trailing-synthetic, and a deliberate text mismatch also bails. * cli — `.catch((err)` widened to `(err: unknown)` on the fire-and-forget `logger.removeLastUserMessage()` call. Belt-and- braces: `Promise.catch`'s lib typing is `(reason: any) =>` so this is not currently TS7006, but tightening keeps the codebase ready for `@typescript-eslint/no-implicit-any-catch`-style rules and matches the rest of the codebase's strict-error patterns. * core — Added a `removeLastUserMessage` regression test pinning the `_readLogFile` failure branch (mocks `fs.readFile` to throw Permission denied). The symmetric `writeFile` failure case was already covered; this closes the gap on the read leg. Tests: AppContainer 67/67 (+2), useGeminiStream 87/87, historyUtils 11/11, logger 50/50 (+1). Type-check and lint clean. * chore(cli): add debug observability for each auto-restore-on-cancel bail-out The cancel handler in AppContainer has seven independent guards that silently `return` when auto-restore is unsafe (buffer non-empty, queue non-empty, pending meaningful content, no last-turn user item, no user in history, trailing items not all synthetic, candidate-text mismatch). Until now, users reporting "I pressed ESC but my prompt didn't come back" had no way to know which guard tripped without a debugger. Log a specific `debugLogger.debug(...)` line at each bail-out and one on the success path. Debug level keeps production output silent; re-enableable by running with `DEBUG=1` (per existing convention in this file). No control-flow change. * docs(core): scope removeLastUserMessage's "false ⇒ observable in-memory" guarantee The previous JSDoc implied the guarantee held for every `false` return, but it only really holds on the disk read/write THROW path (where we roll back the optimistic in-memory removal). Two other `false`-paths behave differently: - Initial guards (logger uninitialized / no tracked entry): nothing was ever removed, nothing to restore — entry stays in whatever state it was already in. - Disk read succeeds but the tracked row is missing on disk (e.g. a concurrent rotation/clear): we adopt disk state into `this.logs`, so both sides agree the entry is gone — `false` is returned but the entry is NOT observable in-memory either. Rewrite the failure-handling paragraph and `@returns` line to spell out both branches explicitly. No code change. * fix(core): shift lastLoggedUserEntry on USER logMessage duplicate-skip When `_updateLogFile` detects another instance already wrote an identical (sessionId, messageId, timestamp, message) row and returns null, the previous logMessage code path left `lastLoggedUserEntry` pointing at the prior USER entry. A subsequent cancel/auto-restore would then call `removeLastUserMessage()` and silently delete the wrong row — typically an older prompt that the user did not intend to undo. The fix: when the duplicate skip happens on a USER attempt, advance `lastLoggedUserEntry` to the entry object we just tried to write. `_updateLogFile` mutates that object's `messageId` in-place to align with the disk row before the duplicate check, so the 5-tuple matches the row that's actually on disk and an undo correctly targets it. The natural race (`max+1` colliding with an existing `messageId`) is not reachable by sequential awaits — the snapshot used for the duplicate check is always max+1-strict. The regression test drives the contract directly by mocking `_updateLogFile` to resolve to null and asserting `lastLoggedUserEntry` shifts to the new entry. * fix(cli, core): strip orphan user entry from chat history on auto-restore The auto-restore branch was cleaning up two of the three places a cancelled prompt lives — the UI transcript via `truncateToItem` and the disk-backed ↑-history via `Logger.removeLastUserMessage`. The third — the in-memory chat history on `GeminiChat` — was left untouched. `sendMessageStream` appends the user content to `chat.history` BEFORE the stream generator runs and the abort path doesn't pop it. After a successful auto-restore the next request's wire payload still carried the cancelled prompt as a leading user turn alongside the new prompt, so the model saw context the user believed had been undone (and in some shapes the API would reject two consecutive user turns). Mirror the existing strip the Retry submit path uses (`GeminiClient.sendMessageStream` at the `Retry` branch): make `GeminiClient.stripOrphanedUserEntriesFromHistory` public and call it from the auto-restore success path, sitting next to the UI truncate and the disk-log undo. The method already pops trailing user entries and clears the `FileReadCache` (which can otherwise hold dangling `read_file` results from the stripped turn). End-to-end reproduction from the PR review: 1. Submit `what time is it?` → ESC during pre-token delay → auto-restore (UI rewound, buffer pre-filled). 2. Edit buffer to `what year is it?` → submit. 3. Pre-fix: outbound `messages` carried both prompts as consecutive user turns. Post-fix: only the new prompt. Test: extend the auto-restore-success AppContainer test with a mock `stripOrphanedUserEntriesFromHistory` spy and assert it fires. The non-restore branches don't install the spy (it's optionally chained at the call site). * fix(core, cli): tighten Logger.serialize signature + pin lastTurnUserItem and dup-skip identity contracts Three follow-ups from PR review batch: * core/logger.ts — `serialize()` was `this.writeQueue.then(op, op)`. The second callback was dead code: `writeQueue` is seeded with `Promise.resolve()` and reassigned through `.catch(() => undefined)`, so the queue tail can never reject. Worse, `then(op, op)` reads as "retry op on rejection" — wrong intent. Switch to `.then(() => op())` with a comment spelling out the no-reject invariant. * cli/useGeminiStream.test.tsx — add ownership-contract tests at the PRODUCER side of `info.lastTurnUserItem`. Until now only the AppContainer tests pinned the contract, and they fabricate the value, so a regression that drops `lastTurnUserItemRef.current = { text: trimmedQuery }` in `prepareQueryForGemini` would slip through. New tests: - normal `UserQuery` submit → cancel → assert `info.lastTurnUserItem === { text: 'what time is it?' }`. - `SendMessageType.Notification` submit → cancel → assert `info.lastTurnUserItem === null` (path doesn't push a user history item, the ref reset at the top of prepareQueryForGemini must keep it null). * core/logger.test.ts — strengthen the duplicate-skip regression. The previous test only checked the tracker advanced text; the important identity contract is that the recalculated 5-tuple matches the disk row, so a subsequent `removeLastUserMessage()` removes the duplicate-skipped row rather than the older USER. New test seeds disk with [first, second], stubs `_updateLogFile` for the second call to mimic the duplicate-skip branch (mutate newEntryObject's messageId+timestamp to align with the disk row, return null), then asserts removeLastUserMessage() leaves ['first'] on disk and removes 'second'. * fix(cli, core): close four cancel-auto-restore correctness gaps from PR review Four critical findings from gpt-5.5 /review pass: 1. **Retry skipped the lastTurnUserItem reset** (useGeminiStream.ts) `Retry` bypasses `prepareQueryForGemini`, which is where the `lastTurnUserItemRef.current = null` reset lived. A retry that followed a normal `UserQuery` carried the stale ownership snapshot into `onCancelSubmit`, and cancelling the retry before any meaningful output let `AppContainer` auto-restore truncate the original failed prompt. Move the reset (and the new content-seen reset, see #4) to the top of `submitQuery`, gated only on "this is a top-level submit" — covers Retry, Cron, Notification, and ordinary UserQuery alike. 2. **Text-only ownership matched dedup'd duplicates** (AppContainer.tsx, useGeminiStream.ts) `useHistoryManager.addItem` skips inserting a consecutive-duplicate user message while still returning a freshly generated id. The text-only ownership check would match the OLDER identical-text USER row, so a re-submitted same prompt + cancel would wrongly truncate the prior turn. Carry id+text in `CancelSubmitInfo.lastTurnUserItem` (using `addItem`'s return value) and require both id AND text to match before truncating. 3. **stripOrphan left IDE context state advanced** (client.ts) Other history-mutating paths (`setHistory`, `truncateHistory`) set `forceFullIdeContext = true` after mutating; the orphan-strip didn't, so a subsequent request could send a diff against a removed baseline. Gate cache-clear + IDE-context invalidation on an actual before/after length drop, so no-op strips don't churn state. 4. **Flush-then-thought race let auto-restore wipe committed content** (useGeminiStream.ts, AppContainer.tsx) `cancelOngoingRequest`'s pre-cancel flush can `addItem` a meaningful `gemini_content` (via handleContentEvent's split path) and then a later thought event overwrites `pendingHistoryItem` with a synthetic value. The AppContainer guard's React history snapshot is stale, so the trailing-only-synthetic check passes and the just-committed text gets truncated. Track a synchronous `turnSawContentEventRef` set in handleContentEvent, ship it through `CancelSubmitInfo`, and make the guard bail when set. Tests: - core/client.test.ts: stripOrphan only forces full IDE context on actual removal; existing retry tests updated to mock `getHistoryLength`. - cli/useGeminiStream.test.tsx: ownership uses { id, text }, Retry reset works after a prior UserQuery cancel, turnProducedMeaningfulContent flips true when content lands. - cli/AppContainer.test.tsx: guard bails on `turnProducedMeaningfulContent: true`, guard bails on id mismatch (catches addItem dedup case). cli 162/162 + core client 99/99 + core logger 51/51. * fix(cli): repaint static transcript after auto-restore truncate Reported by @tanzhenxin: auto-restore truncated React `history` state but the cancelled `> prompt` and `Request cancelled.` lines stayed printed in the terminal — Ink's `<Static>` region is append-only, so shrinking the underlying array doesn't unprint already-flushed lines. On the PR's golden path (type prompt → Enter → ESC) the user sees the prompt twice: once in scrollback, once pre-filled in the input buffer. Confirmed at multiple Enter-to-ESC delays, so it's not a timing fluke. Call `refreshStatic()` immediately after `truncateToItem(...)` in the auto-restore success path. `refreshStatic` writes the ANSI clear-terminal escape AND bumps the static remount key — the exact recipe `/clear` (`handleClearScreen`) already uses for the same reason. The targeted-repaint helper used for terminal resizes is intentionally NOT used here: it preserves scrollback, which would leave the cancelled prompt visible above the new viewport. Test: extend the existing auto-restore happy-path AppContainer test to assert `mockStdout.write` was called with `ansiEscapes.clearTerminal`. The other auto-restore-bail tests don't install the assertion so they naturally verify the negative case (no clear when guard rejects).	2026-05-13 12:08:16 +08:00
ChiGao	720ccaccb7	fix(core): normalize cumulative OpenAI stream deltas to suffixes (#3896) ... Some OpenAI-compatible upstreams (notably specific DashScope / 阿里云百炼 Coding Plan paths) send `delta.content` as accumulated full text instead of incremental suffixes. The Gemini stream pipeline appended every chunk verbatim, so the same content was concatenated repeatedly during streaming. Adds a per-stream `normalizeStreamingTextDelta` that detects cumulative-mode chunks (current chunk starts with previously emitted text) and emits only the suffix. Once cumulative mode is locked in, exact-repeat (≥64 chars) and prefix-overlap chunks are silenced. Normal incremental streams flow through unchanged. The fix applies to both `delta.content` and `delta.reasoning_content` / `delta.reasoning`, with separate state slots so a switch between text and reasoning channels does not cause false-positive suppression. A separate `emittedLength` counter tracks user-visible bytes so an incremental-then-cumulative hybrid stream slices the correct suffix even after the 1024-byte detection-window cap kicks in. Fixes #3279, #1184, #3838, #3806.	2026-05-13 12:05:42 +08:00
Edenman	533daac316	feat(cli): wrap markdown links in OSC 8 so wrapped URLs stay clickable (#4037) ... * feat(cli): wrap markdown links in OSC 8 so wrapped URLs stay clickable Long URLs the model emits inside `[label](url)` or as bare `https://...` get line-wrapped by the terminal, which prevents most emulators from detecting them as a single clickable region. OSC 8 hyperlinks decouple the link target from the visible label so the entire label remains one clickable target regardless of where it wraps. - Extract the existing OSC 8 helpers from AuthenticateStep into a shared packages/cli/src/ui/utils/osc8.ts util, plus a dependency-free capability detector that honors NO_COLOR / FORCE_COLOR=0 / CI / non-TTY stdout, with FORCE_HYPERLINK=1 and QWEN_DISABLE_HYPERLINKS=1 overrides for explicit opt-in / opt-out. - Wire InlineMarkdownRenderer to wrap markdown link labels and bare autolinks in an OSC 8 envelope when supported. Wrapping happens after the inline link token has been fully matched, so streamed partial chunks cannot split an envelope across flushes. - Fall back to the legacy `label (url)` rendering byte-for-byte when the host terminal does not advertise OSC 8 support. Closes #3954 * fix(cli): harden OSC 8 markdown wrapping after multi-round audit Address findings from a multi-round design and code audit of the OSC 8 hyperlink feature: Design fixes: - Keep the visible `(url)` suffix in supported terminals too — preserves copy-paste UX and lets users preview suspicious URLs before clicking. OSC 8 is now purely additive (byte-identical unsupported output, plus envelope on supported terminals). - Restrict OSC 8 wrapping to http/https/mailto/ftp/sftp/ssh schemes; javascript:/data:/file:/vbscript: fall through unwrapped so the user can read the target. Prompt-injection defense for LLM output. - Reject URLs with whitespace — every terminal treats whitespace in an OSC 8 target as truncation/rejection, which would turn the whole region into an un-clickable trap. - Block OSC 8 inside tmux/screen by default; require `FORCE_HYPERLINK=1` opt-in. The multiplexer hides the host terminal's capabilities, so emitting passthrough escapes on a host without OSC 8 prints garbage. - Version-gate `supportsHyperlinks()` (iTerm ≥3.1, vscode ≥1.72, WezTerm ≥20200620, VTE ≥0.50 with 0.50.0 segfault carve-out), block CI / TEAMCITY / win32 (modulo WT_SESSION/Kitty/Ghostty/DOMTERM), mirror `supports-hyperlinks` semantics. - Extend the link regex to allow one level of balanced parens in the URL group so `[wiki](https://en.wikipedia.org/wiki/Foo_(bar))` isn't truncated at the inner `)`. - Trim trailing sentence punctuation off the OSC 8 *target* for bare URLs (`.`, `,`, `;`, `:`, `!`, `?`, `'`, `"`, `` ` ``) and unbalanced trailing `)]}` so the clickable URL resolves to a real page. - Catch VTE 0.50.0 reported in packed form (`'5000'`) — the original string compare missed it and let the segfault through. Code fixes: - Consolidate `wrapForMultiplexer` with the pre-existing `packages/cli/src/utils/osc.ts` — no more duplicate helpers. - Drop the `supportsHyperlinks` memoization cache so runtime env changes (NO_COLOR / theme toggles) take effect immediately. - Extract `MD_LINK_PATTERN`, `MD_LINK_CAPTURE`, `shouldWrapMarkdownLink`, and `HYPERLINK_ENV_KEYS` into `osc8.ts` so the React and ANSI renderers stay in lockstep. - Hoist `supportsHyperlinks()` once per render (both renderers). - Apply the same OSC 8 treatment to `TableRenderer` so markdown links inside tables are clickable too. - Rewrite `trimTrailingUrlPunctuation` to O(n) by pre-counting opens. Tests cover: balanced parens in URL, dangerous-scheme rejection, whitespace-URL rejection, trailing-punctuation trimming, tmux blocking, version gating (iTerm/WezTerm/vscode/VTE incl. packed form), platform fallbacks, mid-stream chunk balance, byte-identical legacy fallback. * feat(cli): detect Alacritty / Konsole / Warp / JetBrains / mintty for OSC 8 Expand supportsHyperlinks() to recognize five more capable terminals that the original detector silently treated as unsupported: - Alacritty ≥ 0.11 via TERM=alacritty (the issue explicitly calls this one out) - Konsole ≥ 21.04 via KONSOLE_VERSION - WarpTerminal via TERM_PROGRAM=WarpTerminal - JetBrains JediTerm (IDE integrated terminals) via TERMINAL_EMULATOR - mintty (Git Bash on Windows, etc.) via TERM_PROGRAM=mintty Hyper stays auto-detection-off (FORCE_HYPERLINK=1 override) because plugin chains have a long history of breaking escape passthrough. Apple_Terminal stays off because it has no OSC 8 support at all. KONSOLE_VERSION and TERMINAL_EMULATOR added to HYPERLINK_ENV_KEYS so the test isolation list stays in sync. * chore(cli): polish OSC 8 detector after another audit round Address findings from the final multi-round audit pass: - Document `FORCE_HYPERLINK` and `QWEN_DISABLE_HYPERLINKS` in the user-facing env-vars table at docs/users/configuration/settings.md so the new opt-in / opt-out surface is discoverable without grepping source. - Detect Alacritty even when the alacritty terminfo entry isn't installed (a common Linux distro scenario where Alacritty falls back to TERM=xterm-256color). Fall back to ALACRITTY_LOG / ALACRITTY_WINDOW_ID / ALACRITTY_SOCKET — Alacritty sets at least one of these unconditionally since 0.12. - Trim a trailing `>` off the OSC 8 target so CommonMark autolinks (`<https://example.com>`) produce a clickable target that actually resolves instead of 404-ing because of the captured delimiter. - Add OSC 8 / hyperlink env isolation to TableRenderer.test.tsx so a developer running the suite from iTerm2 / WezTerm / Kitty can't leak escape bytes into table output. - Symmetric `isTTY` reset in osc8.test.ts `beforeEach` so the early describes (sanitizer, scheme, trim) don't inherit residual TTY state from a prior test. - Document the deliberate security property of keeping the visible `(url)` suffix in OSC 8 mode (user always reads the destination before clicking) in the SAFE_OSC8_SCHEMES comment. - Collapse the `wrapForMultiplexer` import + re-export to a single `export { wrapForMultiplexer }` after the local import. - Add ALACRITTY_* keys to HYPERLINK_ENV_KEYS so test isolation lists stay complete. Tests cover the new autolink `>` trim, the Alacritty env-var fallbacks, and NBSP / Unicode-whitespace URL rejection. * fix(cli): tighten OSC 8 gating per PR review Two fixes from chiga0's review on PR #4037: 1. Move the non-TTY check above `FORCE_HYPERLINK` so a user with `FORCE_HYPERLINK=1` in their shell profile still gets a clean pipe when they run `qwen | cat` or `qwen > out.txt`. The "non-TTY stdout must suppress escapes" acceptance criterion now holds even under forced enable. 2. Version-gate the Konsole detection at `>= 21.04`. KONSOLE_VERSION is set by every Konsole release including ones that pre-date OSC 8 support, so the existence check alone false-positives on Konsole 20.x. Parse the packed integer (21.04 → 210400) and let older releases fall through to the legacy fallback. Updates the docs row for FORCE_HYPERLINK to make the non-TTY caveat explicit. Splits the prior "FORCE_HYPERLINK + isTTY=false" test into two — one verifying force works on a TTY, one asserting it never escapes the non-TTY guard. Adds a Konsole < 21.04 regression test. * fix(cli): stop auto-detecting Warp Terminal as OSC 8 capable Warp's current rendering engine doesn't honor OSC 8 envelopes — the escape sequence is printed as visible garbage rather than recognized as a clickable hyperlink. Falling through to the legacy `label (url)` rendering avoids the regression on Warp. Users on a Warp build that ever ships OSC 8 support can opt in with `FORCE_HYPERLINK=1`; the case will be reinstated in the switch when Warp lands real support upstream. Test flipped from "enabled" to "not auto-detected, FORCE_HYPERLINK opts in" to lock the new behavior. * feat(cli): drop visible (url) suffix when OSC 8 wrapping is active In the originally shipped renderer, `[label](url)` was rendered as `label (url)` even when OSC 8 wrapped the region. With long URLs that's clutter for no benefit — capable terminals already expose the target via hover / status bar / right-click "copy link" without needing the URL in the visible stream. When `shouldWrapMarkdownLink(url, canHyperlink)` returns true, the React renderer and the ANSI table renderer now emit only the markdown label (link-colored), with the OSC 8 envelope pointing at the full URL. Empty labels (`[](url)`) fall back to using the URL as the visible label so the link stays discoverable. When the predicate returns false (unsupported terminal, unsafe scheme, whitespace URL) the legacy `label (url)` rendering is preserved byte-for-byte — the scheme allowlist still guarantees the user sees the destination before any click on a `javascript:` / `data:` / etc. link. Tests updated to assert label-only visible bytes in wrap mode and an empty-label fallback case added. Comment block in `osc8.ts` updated to reflect the new visibility contract. * fix(cli): strip C1 controls in OSC 8 sanitizer sanitizeForOsc() only removed C0 + DEL, so 8-bit ST (\x9c) and 8-bit OSC (\x9d) bytes could still survive inside an OSC 8 target. On terminals that honor C1 controls, those bytes act as the same sequence boundaries as their two-byte ESC counterparts, which defeats the escape-injection hardening this helper is meant to provide. Extend the regex to also strip \x80-\x9f and cover the case with a test. * fix(cli): harden OSC 8 link sanitization and tighten gating Three independent issues found while auditing the markdown OSC 8 path: 1. sanitizeForOsc() previously left Unicode bidi controls (U+200E/F, U+202A-E, U+2066-9) and line/paragraph separators (U+2028/9) intact. A model-emitted RLO in a link label visually reverses trailing bytes, spoofing the host the user thinks they're clicking — exactly the click-deception attack the scheme allowlist is meant to block, just moved from the URL into the visible label. Extend the regex to strip those bytes too. 2. The visible label rendered inside the OSC 8 envelope went straight to the terminal without sanitization, so even with (1) the spoof would still land. Wire sanitizeForOsc() over the linkText in both InlineMarkdownRenderer and TableRenderer's OSC 8 branches. The legacy `label (url)` branches stay untouched so today's unsupported-terminal output remains byte-identical. 3. AuthenticateStep emitted osc8Hyperlink(authUrl) unconditionally, leaking escape bytes into pipes / non-OSC-8 terminals — inconsistent with the suppression contract documented for the rest of the PR. Gate it on supportsHyperlinks() so it falls back to the bare URL. Test coverage added: - sanitizeForOsc bidi/line-separator strip - bidi spoof in the rendered markdown label - byte-equality fallback on unsupported terminals - TableRenderer markdown link → OSC 8 (positive, fallback, unsafe scheme, bidi-spoof) — the table renderer had zero OSC 8 coverage before this. * fix(cli): keep `(url)` visible when an OSC 8 label looks like a different URL Adversarial round-2 audit identified a label-as-URL deception attack: when the OSC 8 branch elides the `(url)` suffix and shows only the clickable label, a model-emitted `[https://google.com](https://attacker.com)` renders a "google.com" link that resolves to attacker.com. Pre-OSC-8 rendering kept `(url)` visible so the user could see the real target; hiding it makes the click-deception case land. Mitigation: a new `labelMayDeceive(label, url)` predicate. When the label contains a URL-shaped substring AND it doesn't equal the actual target, both renderers keep the legacy `(url)` suffix while still emitting the OSC 8 envelope — the link stays clickable, the user still sees where the click goes. Heuristic is permissive on purpose: false positives are harmless (redundant `(url)` on niche labels), false negatives let a real spoof through. Tests: positive (mismatched URL labels), negative (label == url, plain text labels), in both InlineMarkdownRenderer and TableRenderer. * fix(cli): catch bare-host label deception in OSC 8 wrapping Round-3 audit caught a false-negative in labelMayDeceive: the `://` substring check only flagged labels with a fully-qualified URL shape. The most natural markdown spoof — `[google.com](https://evil.com)` — uses a bare host as the label and slipped past, so the OSC 8 branch elided the `(url)` suffix and rendered a clickable "google.com" that resolved to evil.com. Add a third detection pattern: extract host-like tokens from the label (`name.tld` with an alphabetic 2+ char TLD), and flag the link when any of them doesn't equal the URL's parsed hostname. Plain labels like `docs` / `click here` don't match the regex, version strings like `1.2.3` are skipped (last segment is numeric), and `[google.com](https://google.com)` is honest rendering — none of these get flagged. ASCII-only matching means an IDN-homograph attack on a bare-host label (Cyrillic `о`) still escapes this layer; the fully-qualified form of the same attack is still caught by the existing `://` rule, which is the only form an LLM is realistically likely to emit. Tests cover: bare-host mismatch, punycode IDN target, same-host / different-path, label==target negative, plain-text labels, version strings. * fix(cli): handle mailto: target in labelMayDeceive Round-4 audit caught a false positive: `new URL('mailto:x@y').hostname` is empty, so targetHostname() returned undefined and the defensive `return true` branch fired any time a mailto label contained an email-shaped string. A perfectly honest `[support@example.com](mailto:support@example.com)` was being flagged as deceptive and getting a redundant `(url)` suffix on capable terminals. Special-case mailto: by pulling the domain from after the `@` in the URL pathname, matching what the user would compare against. A mismatched mailto (e.g. `[support@example.com](mailto:abuse@evil.com)`) still flags correctly. Also drop a dead `HOST_LIKE_RE.lastIndex = 0` reset — `.match()` doesn't consult lastIndex, so the line was a no-op. * fix(cli): catch IPv4-literal label deception in OSC 8 wrapping Round-5 audit found another bare-host bypass: a label like `[1.1.1.1](https://attacker.com)` (or any other dotted-quad such as `[192.168.1.1]` / `[8.8.8.8]`) escaped labelMayDeceive because the existing host regex anchors on a 2+ alphabetic TLD. The user would see a clickable "1.1.1.1" that resolves to attacker.com with no visible target. Add a separate dotted-quad pattern and combine it with the host-token list before comparing against the URL's hostname. False-positive surface is small (over-permissive on octet ranges is harmless — worst case is an extra `(url)` suffix on a label like `999.999.999.999`). Tests cover mismatched IPv4, IPv4 spelled inside surrounding text, and label-equals-target IPv4 (which must NOT flag). * fix(cli): sanitize URL when rendered as visible text in OSC 8 path Two PR review findings: 1. config-utils.ts dropped the `resolvePath(...)` call (and its import) that origin/main introduced in #4045 for tilde / relative `cwd` paths in channel configs. The auto-merge silently reverted it the same way it did `packages/channels/base/src/index.ts`. Restore main's content. 2. Anti-spoof sanitization was only applied to `linkText`, but the OSC 8 render path emits the URL as visible text in two places that bypassed it: - empty-label fallback `safeLabel || url` — `[](https://x/a‮evil)` would print the URL with RLO intact even though the OSC target was sanitized. - deceptive-label `(url)` suffix. Compute `safeUrl = sanitizeForOsc(url)` once in the OSC 8 branch and use it for both visible-URL renderings. The OSC target inside `osc8Open` keeps the raw URL (sanitization happens inside the helper anyway). Same fix mirrored in `TableRenderer.tsx`. The legacy `label (url)` branch on unsupported terminals stays untouched so its byte-identical-fallback contract holds. Test added: `[](https://example.com/a‮evil)` round-trips through the renderer with the RLO stripped from both the OSC target and the visible URL fallback.	2026-05-13 11:37:27 +08:00

ChiGao	51ee87539c	revert(deps): downgrade ink 7 → 6 to fix Static-remount TUI regression from #3860 (#4083) ... * revert(deps): downgrade ink 7.0.2 → 6.x to fix Static-remount regression from #3860 PR #3860 upgraded ink 6.2.3 → 7.0.2 with the claim of "no business code changes." In production this turns out to break the TUI: - After `/clear`, the next user message and AI response do not render to the static history area — only the dynamic spinner/input area is visible (#3860 + chore/upgrade-ink-7 branch reproduce this). - After Ctrl+O (TOGGLE_COMPACT_MODE), the screen is cleared and stays blank. - Any `refreshStatic()` call path (auth refresh, model change, render- mode switch, /clear, Ctrl+O) puts the UI into the same "muted" state. Root cause is an ink 7 regression: when `<Static>` is remounted by changing its `key` prop, the new instance's items are never written to stdout. A 30-line minimal repro (pure ink + Static + key++) confirms this independently of qwen-code. Closest upstream issue: vadimdemedes/ink#773 (useLayoutEffect-driven child stripping in <Static>). PR #905 ("Fix dangling staticNode reference") merged into ink 7 fixed the unmount-OOM path but not this remount path. No upstream issue yet matches the "remount loses content" case — we should file one and ship a re-upgrade once it is resolved. Scope of this revert (intentional partial revert of #3860): - ink ^7.0.2 → ^6.2.3 (cli + root hoist) - react / react-dom 19.2.4 pin → ^19.1.0 (cli direct, root overrides removed) - wrap-ansi ^10.0.0 → 9.0.2 (cli direct, root override restored) - react-devtools-core kept at ^6.1.5 (still ink-6 compatible — ink 6.8.0's peerOptional requires >=6.1.2; downgrading to 4.x would re-introduce a conflict) - @vitest/eslint-plugin pin "1.3.4" → "^1.3.4" - "@types/node" override removed (was only needed for ink 7's Node 22 type drift) What this revert keeps: - Node engines >=22 across root / cli / core / sdk / web-templates and the matching Dockerfile / .nvmrc / CI matrix work. PR #1876 followed up by adding Node 24 support to the matrix, and rolling those back would conflict with that work. The visible bug is the ink runtime regression, not the engine bump. - doctorChecks.ts MIN_NODE_MAJOR = 22 (matches engines). - The test gating that #3860 added for ink-7 input throttle (AuthDialog / AskUserQuestionDialog / InputPrompt). With ink 6 these tests would pass un-gated, but leaving the gate in place is harmless and a follow-up can un-gate them. Keeping this revert minimal. Verification (local, ink 6.8.0 single instance): - npm ls ink → single ink@6.8.0 - npm ls react → single react@19.2.4 (kept by vscode-ide-companion workspace pin; ink 6 is fine on 19.2) - npm run typecheck --workspace=packages/cli → clean - AppContainer.test.tsx 61/61 pass - MainContent.test.tsx 6/6 pass - clearCommand.test.ts 13/13 pass Re-upgrade path: once ink ships a fix for the Static-remount regression, redo this upgrade behind the feat/virtual-viewport-on-ink7 branch where the `<Static>` + clearTerminal combo is replaced by an overflowY=hidden self-managed viewport. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * ci(fix): keep wrap-ansi 10 + skip 1 ink-7-specific TableRenderer test The initial revert downgraded wrap-ansi to 9.0.2 (the pre-PR-#3860 state). After rebasing onto current main, PR #4050 (preserve table ANSI color across wrapped lines) brought in a new test ("does not preserve foreground after an explicit foreground reset") whose wrap point depends on ink 7's <Text> wrapping behavior. Two-part fix: 1. Restore wrap-ansi to 10 (cli direct dep). The wrap-ansi version is independent of the ink regression we're reverting — wrap-ansi 10 has no peer-dep tie to ink 7 — and #4050's TableRenderer code on main already assumes wrap-ansi 10. Keeping the wrap-ansi bump removes the root override for wrap-ansi (was forcing all transitives to 9.0.2) so cli's TableRenderer gets the wrap-ansi 10 it expects, while ink 6's transitive wrap-ansi naturally resolves to 9 (its own declared range) — no conflict. 2. Skip the one new test that asserts a specific wrap position. The other assertions in that test (foreground cleared, equal visible widths) still pass on ink 6 — only `expectWrappedContinuation` is ink-7-specific. The sibling test 'does not preserve foreground after an explicit reset' (using \\u001b[0m instead of \\u001b[39m) still passes unmodified on ink 6, so the ANSI-handling logic itself is verified end-to-end. The TODO marker references the re-upgrade path. Local verification: - TableRenderer.test.tsx: 54/54 pass + 1 skipped - AppContainer.test.tsx: 61/61 pass - MainContent.test.tsx: 6/6 pass - clearCommand.test.ts: 13/13 pass - npm run typecheck --workspace=packages/cli: clean - npm ls ink → single ink@6.8.0 - npm ls wrap-ansi → cli direct: 10.0.0; ink 6 transitive: 9.0.2 (no conflict, no override) Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> --------- Co-authored-by: 秦奇 <gary.gq@alibaba-inc.com> Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>	2026-05-12 17:11:17 +08:00

Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(cli): cover narrow-terminal rendering branches + tighten thresholds Address review feedback on #3968: - Composer: drop redundant `isStreaming &&` guard from `suppressBottomLoadingIndicator`; the trailing `=== StreamingState.Responding` already implies streaming, and the redundancy risked future drift if `isStreaming` were extended. - Composer.test: add four cases pinning the suppression contract — Responding @ 25/30 cols hides, @ 31 cols shows, and WaitingForConfirmation @ 25 cols still shows so confirmation prompts never disappear on narrow terminals. - TableRenderer: replace the content-agnostic 60-col floor with a column-aware threshold (`max(24, colCount * MIN_COLUMN_WIDTH + borderOverhead + SAFETY_MARGIN)`) so a 2-column table with short values renders horizontally on a ~30-col terminal instead of being forced into vertical mode. The existing `maxLineWidth` post-build check still catches actual overflow. - TableRenderer.test: add explicit horizontal-vs-vertical threshold cases (2 cols @ 60/30/20 and 5 cols @ 30) and bump the alignment tests to contentWidth=60 with `┌` guards so they fail loudly if the threshold ever pushes them back into vertical no-op mode.

Suppressing the full indicator still avoids layout breakage, but the affordance now stays visible. - TableRenderer: clarify that `borderOverhead` is reused by the horizontal-vs-vertical layout threshold so a future change to the border-width formula does not silently shift the threshold. - TableRenderer tests: add equality boundary cases at `ABSOLUTE_MIN_HORIZONTAL_TABLE_WIDTH` (24) and at the 5-column column-budget threshold (35), plus one-below cases, so a future `<` → `<=` regression on the strict comparator is caught. - Composer tests: assert the fallback string is rendered when (and only when) the full indicator is suppressed.

The repo already ships a translated `'Esc to cancel'` key in all 9 locales (used by QwenOAuthProgress and similar). Reuse it and move the parentheses outside the call so the surrounding `()` is layout-only, not translatable. * test(Composer): update esc-fallback assertions to match i18n key casing The cada422f8 fix switched the fallback from `t('(esc to cancel)')` to `({t('Esc to cancel')})` (using the existing translated key).

Matyokubov Umar	664208c420	feat(core): replace fdir crawler with git ls-files + ripgrep fallback (#3214) ... Replaces the fdir filesystem crawler with a three-tier strategy for `@` file mention autocomplete. Strategy: 1. `git ls-files --cached` + `git ls-files --others --exclude-standard` for git repos — reads from the git index, gitignore correctness delegated to git. 2. `ripgrep --files` for non-git directories when `rg` is available. 3. `fdir` as the original last-resort fallback. Additional improvements: - mtime-based change detection on `.git/index` skips re-crawl when nothing changed. - 5s refresh throttling avoids rebuilding the index on every keystroke. - Async chunked indexing yields to the event loop every 1000 entries to stay responsive on 200k+ file trees. - Background untracked-file merge with a 10s timeout. - `resolveGitDir()` correctly handles `.git` as a file (worktrees) including relative `gitdir:` pointers and walks up to parent repos. - POSIX-style path normalization on Windows. - Streaming `spawn()` with line-by-line `onLine` processing and an enforced `maxFiles` budget that terminates the child early, preventing the previous 20MB stdout buffer hazard on large repos. - `--exclude-standard` on the untracked listing so gitignored directories (e.g. `node_modules/`, `dist/`) are not enumerated.

Shaojin Wen	55893875b0	feat(cli): add tools.toolSearch.enabled setting for prefix-caching models (#4069) ... * feat(cli): add tools.toolSearch.enabled setting to disable ToolSearch for prefix-caching models ToolSearch (PR #3589) defers MCP tool loading to reduce prompt size, but breaks prefix-based KV caching for models like DeepSeek V4 where cached token pricing is 1/120 of uncached. Users reported cache hit rates dropping from ~98% to ~81% and 3x cost increases (discussion #4065). Add a `tools.toolSearch.enabled` setting (default: true) that disables ToolSearch by adding tool_search to the deny list, triggering the existing eager-reveal fallback in client.ts. All deferred tools are then included in the initial declaration list, restoring prompt prefix stability. Auto-disable ToolSearch for deepseek-v4-* models when the setting is not explicitly configured, since their extreme cache discount makes prefix stability far more valuable than the ~15K token savings from deferral. Users can override with `tools.toolSearch.enabled: true`. * fix: address PR review — expand model detection, add tests, regenerate schema - Remove ^ anchor from regex to handle provider-prefixed model names (e.g. openrouter/deepseek/deepseek-chat) - Expand auto-detection to all DeepSeek models with prefix caching: deepseek-v3, deepseek-v4-*, deepseek-chat - Add 6 tests covering: explicit disable, auto-detect for v3/v4/chat with provider prefix, non-deepseek skip, explicit enable override - Regenerate settings.schema.json for vscode-ide-companion	2026-05-12 12:04:26 +08:00

Direct `api.anthropic.com` users keep the SDK-default `x-api-key` (`apiKey`) auth and a truthful `QwenCode` User-Agent so usage isn't misattributed in Anthropic's logs/quotas, and so a stricter Anthropic backend doesn't 401 on a `Bearer`-shaped header. - Gate the `prompt-caching-scope-2026-01-05` beta on `enableCacheControl`. When the converter isn't attaching `cache_control` to the body the beta is dead weight and risks 4xx responses from anthropic-compatible backends that don't recognize it. Restores the `betas.length === 0` early-return for the all-disabled case. - Detect adaptive-thinking models with numeric major/minor compare instead of `[6-9]`. The character class missed `claude-haiku-4-6` entirely and would silently fall through to `budget_tokens` on `claude-opus-4-10` / `claude-opus-5-1` once those ship — tripping HTTP 400 with a shape the server no longer accepts. - Honor explicit `reasoning.budget_tokens` before the adaptive branch. Adaptive omits `budget_tokens` from the wire shape, so checking it second silently dropped a user-supplied escape-hatch budget on Claude 4.6+ models. - Add `scope: 'global'` on the tool `cache_control` entry so the largest, slowest-changing prefix actually participates in cross-session caching under the new beta — the system-only attachment was capturing maybe half the available hit-rate improvement. - Replace the misleading `as { type: 'ephemeral' }` cast on the system block (which erased `scope` from the type while leaving it on the wire) with a `AnthropicTextBlockParam` type that mirrors the existing `AnthropicToolParam` widening, so types match the runtime shape. * fix(core): keep enableCacheControl live in the converter Follow-up on PR #4020 review: `Config.setModel()` mutates `enableCacheControl` in place (it's in `MODEL_GENERATION_CONFIG_FIELDS`), but the converter captured it once at construction. On a hot flip the generator's per-request `prompt-caching-scope-2026-01-05` beta gate would sample the new value while the converter still emitted the old body-side `cache_control` — beta-header and body could disagree. - Thread the live `contentGeneratorConfig.enableCacheControl` into the converter via a per-call options override on both `convertGeminiRequestToAnthropic` and `convertGeminiToolsToAnthropic`, falling back to the constructor-time default when the caller doesn't pass one. The generator samples the value once per `buildRequest` and forwards it to both convert calls so the body and beta header always agree within a request, even across `setModel` flips. - Regression test: hot-flip `enableCacheControl` from `true` to `false` on a live generator, verify the 2nd request drops both the beta header AND the body-side `cache_control` in lockstep. - Tighten two existing beta-header tests that used `toContain` only on `interleaved-thinking` / `effort` — they now also assert `prompt-caching-scope-2026-01-05` is present (per-request keep-default and streaming paths), so accidental removal trips the test. - Add coverage for the two previously-uncovered branches of `isAnthropicNativeBaseUrl`: `*.anthropic.com` subdomains (Anthropic-native) and a malformed baseURL (URL parse failure → proxy fallthrough). Also add an `anthropic.com.evil.com` hostname-spoof case mirroring the existing DeepSeek spoof test. * refactor(core): consolidate anthropic generator shapes & document edge cases Follow-up on PR #4020 review: - Extract `AnthropicThinkingParam` type alias. The thinking union `{ type: 'enabled'; budget_tokens } | { type: 'adaptive' }` was repeated verbatim in three places: the `MessageCreateParamsWithThinking` field, the streaming-request intersection, and `buildThinkingConfig`'s return type. Once a third shape ships, forgetting one site would silently narrow a runtime value — single alias keeps them locked. - Compute `useProxyIdentity` once in the constructor and pass it into `buildHeaders`. Previously `useBearerAuth` and `useProxyIdentity` named the same predicate at two call sites; collapsing them clarifies that Bearer auth + `claude-cli` UA + `x-app: cli` are one bundle that should never be split. - Document that `modelSupportsAdaptiveThinking`'s regex is intentionally unanchored so reseller-prefixed names (`bedrock/claude-opus-4-7`, `vertex_ai/claude-sonnet-4-6@…`, `idealab:claude-opus-4-6`, …) keep matching. Tightening to `^claude-` would silently regress those. - Soften the `prompt-caching-scope` beta comment so it describes what the code enforces (gate on the `enableCacheControl` flag) rather than promising a stronger "only ship when cache_control is on the body" invariant — the converter still skips `cache_control` on niche shapes (e.g. no system text, no tools, last user block isn't text). The looser gate is intentional; Anthropic-native ignores unused betas. - Pin the wire shape for the `reasoning: undefined` + 4.6+ model corner. `resolveEffectiveEffort` returns undefined on `reasoning === undefined`, so `buildThinkingConfig` ships `{ type: 'adaptive' }` with no `output_config` and no `effort-2025-11-24` beta. If Anthropic ever starts requiring `output_config.effort` alongside adaptive, this test will fail at CI rather than at runtime as a server 400. * fix(core): gate cache-scope on Anthropic-native baseURL, mirror auth gate Follow-up on PR #4020 review: the `prompt-caching-scope-2026-01-05` beta header and the body-side `scope: 'global'` field together comprise an Anthropic-only wire-shape extension. Shipping them to non-Anthropic backends (DeepSeek, IdeaLab) leaned on "unknown betas are ignored" — true on Anthropic-native, but unverified for proxies and silently inconsistent with the auth/identity gate, which already uses `isAnthropicNativeBaseUrl` to bind Bearer / claude-cli / x-app to the proxy path only. - Add `useGlobalCacheScope` predicate on the generator. True iff `enableCacheControl !== false` AND the resolved baseURL is Anthropic-native. Plumbed per-request into both `convertGeminiRequestToAnthropic` and `convertGeminiToolsToAnthropic`; the same predicate also gates the `prompt-caching-scope-2026-01-05` beta in `buildPerRequestHeaders` so beta + scope field always travel together. - Converter emits `cache_control: { type: 'ephemeral' }` (per-session) when scope is off and `{ type: 'ephemeral', scope: 'global' }` when on. Non-Anthropic baseURLs go back to their pre-PR per-session caching shape; existing prompt caching keeps working with no new beta. - Document the intentional `scope: 'global'` omission on `addCacheControlToMessages`. The last user message changes every turn (live prompt + immediate tool_results), so cross-session reuse has effectively zero hit rate; cross-session caching is concentrated on system + tool prefixes only. Tests: - DeepSeek baseURL pins the proxy auth/identity path (`authToken` / claude-cli UA / `x-app: cli`). Documents the contract assumption that DeepSeek's anthropic-compatible endpoint accepts `Authorization: Bearer` — any future deviation surfaces here rather than at runtime for users. - Non-Anthropic baseURL strips the cache-scope beta AND `scope: 'global'` from the wire shape, while keeping per-session `cache_control: { type: 'ephemeral' }` on system / tools. - Hot-flip test extended to assert tool `cache_control` flips alongside system / user / beta header. - Converter-level tests for per-call `enableCacheControl` and `useGlobalCacheScope` overrides — both directions of the constructor default (true→false, false→true) and the scope-independent-of-source case (cache on, scope off → per-session shape). - baseConfig in the per-request anthropic-beta block now targets `api.anthropic.com` so cache-scope assertions remain meaningful; the proxy-baseURL behavior is covered separately. * docs(core): tighten useGlobalCacheScope JSDoc — baseUrl is NOT hot-mutated #4020 review: the JSDoc claimed `Config.setModel()` mutates both `enableCacheControl` AND `baseUrl` in place. Per the current Config implementation, only the qwen-oauth hot-update path mutates `enableCacheControl` in place; non-qwen-oauth providers go through the refresh path which recreates the ContentGenerator (so `baseUrl` is captured fresh at construct time, not mutated). Tightened the wording to reflect actual behavior + kept the read-both-each-request defense (cheap and avoids stale-cache surprises if the hot-update list ever expands). * fix(core)!: suppress env back-fill so proxy auth doesn't leak real Anthropic key #4020 review (tanzhenxin, severity high): the IdeaLab-proxy branch spread `{ authToken: <key> }` and omitted `apiKey` entirely. The Anthropic SDK constructor destructures with defaults (`apiKey = readEnv('ANTHROPIC_API_KEY') ?? null`), and destructuring defaults only fire for `undefined` — so an omitted `apiKey` lets `ANTHROPIC_API_KEY` back-fill it. The SDK's auth resolver then prefers `apiKey` over `authToken`, shipping `X-Api-Key` (not `Authorization: Bearer`) on the wire. Concrete impact: a user with `ANTHROPIC_API_KEY=sk-ant-…` exported (normal for anyone also running Claude Code in the same shell) configuring qwen-code with an IdeaLab proxy plus an IdeaLab token would leak their real Anthropic key as `X-Api-Key` to the third-party proxy endpoint. - Pass `apiKey: null` explicitly on the proxy branch and `authToken: null` on the Anthropic-native branch. Explicit `null` suppresses the destructuring default; the env back-fill no longer fires. - New helper `resolveEffectiveBaseUrl` mirrors the SDK's own destructuring order (config → `ANTHROPIC_BASE_URL` env → SDK default). `isAnthropicNativeBaseUrl` now consults the env too, so a user configuring the proxy purely through `ANTHROPIC_BASE_URL` (qwen-code `baseUrl` unset) gets the proxy identity bundle instead of silently shipping native auth + UA + cache-scope beta to the proxy. Tests: - ANTHROPIC_API_KEY env + proxy baseURL → ctor receives `apiKey: null` and `authToken: our-key`. Locks in the credential-leak fix. - ANTHROPIC_AUTH_TOKEN env + Anthropic-native baseURL → ctor receives `authToken: null` and `apiKey: our-key`. Symmetric guard for the inverse direction. - ANTHROPIC_BASE_URL env points to proxy, config.baseUrl unset → proxy identity bundle (claude-cli UA, x-app, Bearer auth) applies. - ANTHROPIC_BASE_URL unset → SDK default api.anthropic.com path keeps native identity (predicate doesn't misclassify the SDK default as a proxy). - config.baseUrl wins over ANTHROPIC_BASE_URL — mirrors the SDK's own resolution order. - Existing 7 identity tests updated from `toBeUndefined()` to `toBeNull()` to match the new explicit-suppression contract. * refactor(core): gate cache-scope beta on body presence, not just predicate #4020 review (Copilot): the comment promised "beta and body-side scope: 'global' field always ship together" but the gate was just `useGlobalCacheScope()`. In the degenerate case where the predicate is true but the request body has no system text AND no tools, the beta would still ship without any matching `cache_control.scope: 'global'` on the wire — overstating the contract and shipping dead weight. - New `hasGlobalCacheScopeOnWire(req)` scans the assembled request body (system block when shaped as `TextBlockParam[]`, tools array) for any `cache_control: { …, scope: 'global' }` entry. `buildPerRequestHeaders` gates the `prompt-caching-scope-2026-01-05` beta on this scan, so the beta and the body field share a single source of truth. No window between sampling the predicate and emitting the body where the two could diverge. - `useGlobalCacheScope()` is still sampled once per `buildRequest` and threaded into the converter to decide whether to ATTACH `scope: 'global'` to the body. The body-scan downstream then derives the beta from what actually landed. Tests: - New: empty systemInstruction + no tools + Anthropic-native + cache on → beta NOT shipped (degenerate body-scan case). - New: empty systemInstruction + non-empty tools → beta shipped (tool scope:'global' triggers the scan). - Existing per-request beta tests now include a `systemInstruction` so the body has the scope field; degenerate case is covered by the new dedicated test. Also tightened two stale comments (#3217834451, #3217834505) that claimed `Config.setModel()` mutates both `enableCacheControl` and `baseUrl` in place — only `enableCacheControl` is hot-mutated (qwen-oauth path); non-qwen-oauth providers recreate the generator on refresh, so `baseUrl` is captured fresh at construct time. Comments now describe the real in-place mutation and note the qwen-oauth boundary. * fix(core): trim config.baseUrl and document x-app in buildHeaders #4020 review (Copilot): two low-stakes follow-ups on 491a441f9. - `resolveEffectiveBaseUrl` trimmed `ANTHROPIC_BASE_URL` env but returned `contentGeneratorConfig.baseUrl` as-is. A copy-pasted baseURL with leading/trailing whitespace would trip `new URL(...)` in `isAnthropicNativeBaseUrl` and fall through the catch branch to the proxy identity bundle — meaning real api.anthropic.com would receive Bearer auth + claude-cli UA and 401.

tanzhenxin	8beb97eecf	feat(tools): keep ask_user_question always-visible to surface clarification UX (#4041) ... Previously ask_user_question was deferred behind ToolSearch (shouldDefer: true), so the model only saw it as a name in the deferred-tools section and had to discover it via tool_search before invoking. In practice the model rarely went through that discovery step and instead asked clarifying questions in plain prose, losing the structured multiple-choice UX the tool exists to provide. Flip shouldDefer to false so the schema lives in the initial tool list. Add a unit-test guard so a future refactor doesn't silently put it back behind ToolSearch.	2026-05-11 19:06:03 +08:00
tanzhenxin	d7a25682e6	refactor(core): route side-query LLM calls through runSideQuery chokepoint (#3775) ... * refactor(core): route side-query LLM calls through runSideQuery chokepoint Folds every one-shot side-query call site through a single `runSideQuery` entry point with `thinkingConfig.includeThoughts: false` and `fastModel` (falling back to main) as the default policy. Adds a text-mode sibling to the existing JSON-mode helper, plus a `BaseLlmClient.generateText` primitive that calls `ContentGenerator.generateContent` directly so side queries get neither user-memory wrapping nor the main-prompt fallback that `geminiClient.generateContent` applies. Migrated call sites: session title, recap, tool-use summary, /rename, follow-up suggestion (direct path), ACP rewrite, project /summary, arena approach summary, chat compression, web-fetch, insight analysis, subagent spec generation. Six call sites override the helper defaults explicitly (subagent gen, suggestion, ACP rewrite, /summary, compression, insight) where main-model quality or caller-supplied model matters. The /summary path additionally fixes a latent bug: text extraction previously did not strip thought parts, so on thinking models the saved `.qwen/PROJECT_SUMMARY.md` could leak `reasoning_content` into the file. The chokepoint now strips thought parts and the request itself goes out with thinking off. Best-effort cosmetic callers (recap, tool-use summary, kebab rename, suggestion) opt into `maxAttempts: 1` so transient outages don't burn seven retries on output the user will likely never see. `isInternalPromptId` recognises the `side-query:` prefix automatically so new call sites are filtered without per-site allowlist updates. Removes the `getAgentContentGenerator` workaround in `InProcessBackend` and the `getAgentSummaryGenerator` indirection in `ArenaManager` — arena approach summaries now run through the chokepoint against `fastModel`, giving every agent a neutral arbiter rather than a self-summary on its own model. * fix(core): guard isInternalPromptId against undefined prompt_id logToolCall calls isInternalPromptId(event.prompt_id), and tool-call events from useToolScheduler can carry an undefined prompt_id. The side-query refactor added promptId.startsWith(SIDE_QUERY_PROMPT_PREFIX) without a falsy guard, so the missing id crashed the logger and broke six useToolScheduler tests across all OS / Node matrix entries on CI. * fix(cli,core): polish runSideQuery callers from review feedback - Cap web-fetch, chat-compression, and ACP rewrite at maxAttempts: 1. These paths degrade gracefully on failure (tool error, NOOP fallback, null return), so 7 retries only delays the user-visible outcome. - /summary now carries the main session's system instruction so the summarizer keeps the coding-assistant role, project context, and user memory instead of summarizing the chat in isolation. - Add isInternalPromptId tests for the side-query: prefix so future callers minted via runSideQuery stay filtered out of recordings. * refactor(core): document runSideQuery defaults and surface promptId in errors - Add JSDoc on the model and config fields of SideQueryJsonOptions and SideQueryTextOptions so the fastModel-first defaulting and the thinkingConfig.includeThoughts: false default are visible at the API surface, not buried in resolveDefaultModel / applyThinkingDefault. - BaseLlmClient.generate{Json,Text} error wraps now include promptId in the message and pass { cause: error }, so a side-query failure identifies which call site failed and preserves the original stack. - Add tests covering maxAttempts forwarding (present + omitted) and rejection propagation for both JSON and text modes — the conditional spread is non-trivial and was previously unverified. * fix(core): preserve per-model provider routing in side queries BaseLlmClient was bound to the main session's ContentGenerator and only swapped the request `model` field, so side queries targeting a fast or alternate model inherited the main provider's baseUrl, credentials, and sampling settings — breaking cross-provider configurations. Move per-model generator/authType resolution out of GeminiClient and into BaseLlmClient as `resolveForModel`. Both generateJson and generateText now build a per-model ContentGenerator (with cache) when the request targets a non-main model and pass the resolved retry authType through to retryWithBackoff. GeminiClient.generateContent delegates to the same resolver so there is a single source of truth. Also pin the /forget destructive selector to the main model — the runSideQuery default moved to fast model in this branch, but /forget acts on the selection without confirmation, so a weaker fast model could silently delete the wrong managed-memory entries. * test(core): assert thinkingConfig/maxAttempts/model forwarding in compression The compression caller of runSideQuery sets thinkingConfig.includeThoughts=true and maxAttempts=1. A future refactor that silently drops either would degrade compression quality without test failure; this assertion locks the contract. * fix(cli): route dynamic localization through side query * refactor(core): remove unused memory governance review	2026-05-11 19:03:14 +08:00

The lockfile had no nested install under node_modules/ink/, so ink 7 was running with a transitive dep one major below its declared minimum. Dropping the global override lets ink resolve its own wrap-ansi 10 nested install (now visible in the lockfile under node_modules/ink/node_modules/wrap-ansi), while the cli package's own direct `wrap-ansi: 9.0.2` dependency keeps the cli code path (TableRenderer.tsx) on the version it has been tested against. The nested cliui override is preserved for yargs which still needs v7. Verified via `npm ls wrap-ansi`: - ink@7.0.2 -> wrap-ansi@10.0.0 (newly nested) - @qwen-code/qwen-code -> wrap-ansi@9.0.2 (unchanged) - yargs/cliui -> wrap-ansi@7.0.0 (unchanged) Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(InputPrompt): un-skip placeholder ID reuse after deletion Reviewer (tanzhenxin) flagged that the new it.skip on the 'should reuse placeholder ID after deletion' test was undisclosed in the PR description and removed coverage of real product behavior (freePlaceholderId / bracketed-paste backspace path) without a TODO(#NNNN) link. Their argument was sound: the skip rationale pointed at ink 7's input throttle, but this same file just bumped the wait helper from 50ms to 150ms specifically to give ink 7 frame time. Re-running the test under the bumped wait shows it passes reliably (5/5 runs in the full-file context, 9/10 alone), so the skip was masking the throttle-flake that the wait bump already addresses, not a real product bug. Drop the it.skip and the now-stale comment so coverage of the freePlaceholderId reuse logic is restored.

Match the 350ms initial render wait used immediately above to absorb the cold start. * Revert "test(InputPrompt): bump first prompt-suggestion test wait to 350ms" This reverts commit 6add83b62e. * test(InputPrompt): wait for followup suggestion debounce before pressing Enter Root cause of the failing prompt-suggestion tests on macOS and Windows CI is not flaky timing of the test post-Enter wait — it's the 300ms debounce inside createFollowupController.setSuggestion (shared core). The Enter handler reads followup.state.isVisible synchronously, so if the debounce timer has not fired before stdin.write('\\r'), the suggestion path is skipped and onSubmit never runs. No amount of post-Enter wait can recover from that — the keypress was already processed against stale state. The original wait(350) only left ~50ms margin over the 300ms debounce, which ink 7 / React 19.2 mount overhead consumed on slow Windows runners. Bump the initial wait to 700ms (named SUGGESTION_VISIBLE_WAIT_MS) to give the debounce timer + cold-start render a generous buffer. Apply to the two sibling tests too — without the wait their "does not accept" assertions pass trivially when suggestion is never visible, which is a false green that hides regressions in the actual reject path. * fix(deps): align cli wrap-ansi with ink 7 (9.0.2 -> ^10.0.0) Ink 7 ships its own wrap-ansi@10. CLI's direct dep was pinned to 9.0.2, causing two copies of wrap-ansi in node_modules and a potential drift in CJK width / ANSI handling between ink's internal text wrapping and our TableRenderer. Upgrading the CLI's direct dep to ^10.0.0 lets npm dedupe to a single wrap-ansi@10 used by both ink and TableRenderer. API surface is identical; the only documented behaviour change is that tabs are expanded to 8-column tab stops before wrapping, which TableRenderer doesn't feed in. TableRenderer test suite (43 tests) passes against wrap-ansi@10.

pomelo	7e11428545	refactor(cli): remove legacy qwen auth CLI subcommand, redirect to /auth TUI dialog (#3959) ... The `qwen auth` CLI subcommand (with subcommands like qwen-oauth, coding-plan, api-key, openrouter, status) has been superseded by the richer /auth TUI dialog introduced in the provider-first auth registry (#3864). Running `qwen auth` now prints a deprecation notice pointing users to the /auth TUI dialog (interactive), env vars (CI/headless), or /doctor (status check). Changes: - Replace auth.ts with a stub that prints a removal notice and exits - Delete handler.ts (734 lines), interactiveSelector.ts, and their tests (interactiveSelector.test.ts, openrouter.test.ts, status.test.ts) - Update /auth slash command to handle non-interactive/ACP modes gracefully - Enrich /doctor auth check with provider-aware diagnostics using findProviderByCredentials - Mark `auth` as a subcommand that handles its own exit in config.ts Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>	2026-05-11 16:44:09 +08:00
Shaojin Wen	84ecb5b8a3	feat(cli): add --json-schema for structured output in headless mode (#3598) ... * feat(cli): add --json-schema for structured output in headless mode Registers a synthetic `structured_output` tool whose parameter schema IS the user-supplied JSON Schema. In headless mode (`qwen -p`), the first successful call terminates the session and exposes the validated payload via the result message's `structured_result` field. Invalid schemas are rejected at CLI parse time via a new strict Ajv compile helper so they can't silently no-op at runtime. * fix(cli): honour "first structured_output call ends session" + reject non-object root schemas Two review fixes for the `--json-schema` feature: 1. `runNonInteractive` now breaks out of the tool-call loop as soon as the first successful `structured_output` invocation is captured, rather than continuing to execute any trailing tool calls the model emitted in the same turn. This restores the documented single-shot contract and prevents side-effecting tools from running after the final answer has already been accepted. 2. `resolveJsonSchemaArg` rejects schemas whose root `type` is anything other than "object" (or a type array including "object"). Function- calling APIs require tool arguments to be JSON objects, so a schema like `{"type": "array"}` would have registered an unusable synthetic tool the model could never satisfy. Absent `type` and `type: "object"` remain accepted. Adds tests for both paths and updates the existing Ajv-compile test to exercise that path without tripping the new root-type guard first. * fix(cli): also reject root anyOf/oneOf schemas whose branches can't accept objects Addresses a review follow-up: the previous root-object check only inspected the top-level `type` keyword, so a schema like `{"anyOf":[{"type":"array"},{"type":"string"}]}` slipped through even though none of its branches can ever validate the object-shaped arguments that function-calling APIs send. Replace the single `type` check with `schemaRootAcceptsObject`, which recursively walks root-level anyOf/oneOf branches and requires at least one to accept objects. Absent `type`, `type: "object"`, `type: ["object", ...]`, and mixed anyOf branches where one accepts object all still pass. `allOf` is left to Ajv's runtime behaviour — guessing intent across contradictory allOf branches at parse time is fragile. * fix(cli): propagate exitCode from --json-schema failure path + tests Address two PR-3598 review findings: 1. gemini.tsx unconditionally called process.exit(0) after runNonInteractive/runNonInteractiveStreamJson, clobbering the process.exitCode = 1 set by nonInteractiveCli.ts when the model emits plain text instead of the structured_output tool. Switch both call sites to process.exit(process.exitCode ?? 0) so CI can detect the failure via the exit code. 2. nonInteractiveCli.test.ts: strengthen the structured-output success path to assert registry.abortAll() is called and that the stdout result envelope carries the JSON-stringified args under `result` plus the raw object under `structured_result`. Add a retry-path test that mocks executeToolCall to return an error on the first structured_output call, then verifies sendMessageStream is called a second time so the model can retry rather than the session terminating early. * fix(cli): suppress non-structured tool calls when structured_output is in the same turn When --json-schema is active and the model emits a batch like [write_file(...), structured_output(...)], the previous implementation ran the leading side-effecting tool before accepting the structured result, violating the "structured_output is the terminal contract" guarantee. The trailing-only break also let an invalid first structured_output fall through to subsequent tools before the retry turn. Pre-scan the batch: if a structured_output request is present, execute ONLY the first one and skip everything else (leading and trailing). This is consistent with the existing terminal-path semantics — the suppressed tool_use blocks lack a matching tool_result, the same way max-turns / cancellation leave the stream. Adds a test covering the reverse-order [side_effect, structured_output] case alongside the existing trailing-suppression and retry tests. * fix(cli): tighten --json-schema root validation per review feedback Three small holes flagged in the latest pass: 1. `schemaRootAcceptsObject` returned early when a root `type` keyword was present, ignoring sibling `anyOf`/`oneOf`. JSON Schema applies keywords at the same level conjunctively, so e.g. `{type:"object", anyOf:[{type:"string"}]}` is unsatisfiable for any value but used to pass. Now both `type` AND any sibling `anyOf`/`oneOf` must independently admit object. 2. The FatalConfigError text said "Every branch of a root anyOf/oneOf must be satisfiable by an object", but the actual logic only requires *at least one* branch (and tests still accept `anyOf:[object, string]`). Reworded to "at least one branch" so the message matches the behaviour. 3. `compileStrict` used `typeof schema !== 'object'` to gate input, which lets arrays through (`typeof [] === 'object'`). The contract says "schema must be a JSON object", so add an `Array.isArray` check so array input gets the intended error rather than a less helpful Ajv compile message. Tests cover the new rejection paths and the array case. * fix(cli): handle root $ref and allOf in --json-schema accept-object check `schemaRootAcceptsObject` previously only inspected `type`, `anyOf`, and `oneOf` at the root, so a couple of unsatisfiable shapes still slipped through: 1. `{"$ref":"#/$defs/Foo","$defs":{"Foo":{"type":"array"}}}` would be accepted because we don't follow $refs, but registers a synthetic tool whose params resolve to "array" — the model can never produce a valid object. Now reject any root $ref unless the user adds a sibling `type:"object"` as an explicit anchor. 2. `allOf` was deferred to Ajv runtime, but allOf is conjunctive at the same level as `type` / `anyOf` / `oneOf`, so an entry like `{"allOf":[{"type":"object"},{"type":"string"}]}` is unsatisfiable for any value. Walk it like the others, requiring every branch to admit object. Tests cover the new $ref-rejected / $ref+anchor-accepted paths and the allOf reject/accept paths. * fix(cli): explicit exit code from runNonInteractive + pair suppressed tool calls Three review threads on the structured-output flow: 1. The break that ends the for-loop on a successful structured_output call sat *before* the responseParts.push and modelOverride capture. SyntheticOutputTool currently returns neither, so it was safe today — but anyone wiring extra signals into the synthetic tool later would see them silently dropped. Move the break after both captures so the contract is explicit, not implicit. 2. The failure path used to set process.exitCode = 1 and return void, relying on global mutable state across an async boundary. Any cleanup task between runNonInteractive and process.exit could silently turn the structured-output failure into exit 0. Switch runNonInteractive to Promise<number>, return 0 / 1 directly from each function-level exit, and have gemini.tsx use the captured return value. 3. The pre-scan from the prior commit suppresses sibling tool calls when structured_output is in the same turn. On the retry path — when structured_output fails validation — the next-turn payload has tool_result for structured_output but no entry for the suppressed siblings, leaving the prior assistant turn's tool_use blocks unpaired. Anthropic and OpenAI both reject that batch shape, so the retry would surface as an opaque provider error. Synthesize a "skipped" functionResponse for every suppressed call so every tool_use in the prior assistant message has a matching tool_result. Tests cover the new retry-pairing contract and update the existing plain-text-failure test to assert on the return value rather than process.exitCode. * fix: address Copilot follow-up review on --json-schema scaffolding Five small but real findings flagged on the latest pass: 1. core/src/index.ts re-exported `SyntheticOutputTool` via `export type`, but it's a runtime class — that erased it from the emitted JS and would break value imports. Split into a value `export { ... }` and a `export type { StructuredOutputParams }`. 2. The structured-output success path returned without flushing `localQueue` notifications or finalising one-shot monitors. If a background task had already emitted `task_started`, exiting here could drop its paired `task_notification` and leave SDK consumers with unpaired lifecycle events. Mirror the regular terminal path's `flushQueuedNotificationsToSdk` + `finalizeOneShotMonitors` calls before `emitResult`. 3. `schemaRootAcceptsObject` ignored the `not` keyword, so `{not:{type:"object"}}` (which forbids every object value) slipped through. Add a best-effort `not` check that rejects when `not.type` directly excludes object. Deeper negated patterns still fall through to Ajv at runtime. 4. `compileStrict`'s JSDoc claimed it errored on "Ajv versions we can't support", but the function doesn't actually check Ajv versions. Reword to "malformed or uses unsupported draft/features for our Ajv configuration" so the contract matches the implementation. 5. The pre-scan suppressed sibling tool calls but only synthesised tool_result events for them on the retry path — the success path left those tool_use blocks unpaired in the emitted JSONL/stream-json event log. Move the synthesis after the for loop so it runs for both the success break and the validation-failure fall-through; the event log is now consistent regardless of which path the run takes. Tests cover the new \`not\`-rejection paths, the success-path tool_result synthesis, and the existing retry-pairing test still passes against the restructured emit ordering. * fix(cli): tighten --json-schema parse-time gate per Copilot review Two more shapes that used to slip through: 1. `schemaRootAcceptsObject` defaulted to true when no narrowing keyword was present, so root-value constraints like `{const: 1}` or `{enum: [1, 2]}` registered an unsatisfiable structured_output contract — the model could never produce a value matching the tool's parameter schema, and the run would loop on validation failures until max-turns. Reject `const` whose literal isn't an object, and `enum` whose members include no object. 2. The yargs check rejected `--json-schema` with `-i` and with no prompt, but not with `--input-format stream-json`. Stream-json keeps the process open waiting for protocol messages, so "terminate on the first valid structured_output call" silently drops everything queued after that point. Refuse the combination at parse time so the contradiction surfaces immediately. Tests cover the new const/enum reject and accept paths. * fix(cli): handle empty/boolean subschemas + allow stdin-only prompt Three more shapes flagged on the latest review pass: 1. `schemaRootAcceptsObject` treated an empty root `anyOf`/`oneOf` as "no constraint" (skipped when length === 0), but per JSON Schema an empty union is unsatisfiable — no value can match a member of the empty set. Reject those at parse time so users get a clear parse error instead of an opaque runtime never-validates loop. 2. JSON Schema (draft-06+) allows boolean subschemas anywhere a schema is accepted: `true` matches every value, `false` matches nothing. The `anyOf`/`oneOf`/`allOf` walks were rejecting booleans via the typeof-object guard, which incorrectly rejected `{anyOf:[true]}` and `{allOf:[true,{type:"object"}]}` while letting `{anyOf:[false]}` slip through. Replace the per-branch object guard with a `variantAcceptsObject` helper that treats `true` as accepting and `false` as rejecting, then recurses on object subschemas. 3. The yargs `.check` rejected `--json-schema` when no `-p` / positional prompt was given, but the headless CLI also reads the prompt from stdin (`cat prompt.txt | qwen --json-schema '...'`) — a legit usage pattern that was being blocked. Drop the parse-time no-prompt rejection; the existing runtime "No input provided via stdin..." error in gemini.tsx still catches genuinely empty input. Tests cover the empty-union, all-`false`, mixed-boolean accept, and `false`-in-allOf reject paths. Live-verified against the bundled CLI: `echo "..." | qwen --json-schema '...'` now reaches the model call, and the four schema edge cases all surface the expected error text or proceed past parse time. * docs(core): note SyntheticOutputTool as the value-export exception The block comment above the lazy-load type re-exports said tool classes "are now lazy-loaded and are not exported as values from the package root", but `SyntheticOutputTool` was just promoted to a runtime export in 62038527c so the CLI's `--json-schema` flow can construct it from the package root. Document that exception inline so downstream consumers reading the comment don't get told the wrong story. * fix(cli): try every structured_output in a same-turn batch in order The pre-scan used to pick only the FIRST structured_output call from a turn and suppress everything else, even other structured_output calls. That created two avoidable failure modes: 1. `[structured_output(bad), structured_output(good)]` would attempt only the bad one, fail validation, and force a full retry turn. The model already produced a valid structured payload — we should try it before asking again. 2. The trailing structured_output's tool_result was synthesised with the "Skipped: structured_output was also requested in this turn..." message, which is misleading because that call WAS the structured output we should have tried. Filter `requestsToExecute` to ALL structured_output calls (in original order) when --json-schema is active, and let the existing loop break on the first success. Track an `executedCallIds` set, then synthesise tool_result + retry parts after the loop for every tool_use the model emitted that we never actually executed — covering both non-structured siblings (always suppressed) and any structured_output left over after the success break (only one terminal contract per turn). Reworded the synthesised "skipped" output to "this turn's structured_output contract took precedence" so it reads correctly regardless of whether the suppressed call was structured or not. Tests cover the multi-structured retry-free success path; the existing single-structured retry and trailing/leading suppression tests still pass against the updated emit ordering. * fix: address gpt-5.5 review on --json-schema (privacy + $ref + core-tools) Three findings, three changes: 1. Reject every root `$ref` in --json-schema, even with a sibling `type: "object"` anchor. Ajv applies `$ref` conjunctively with sibling keywords, so the previous "accept when type:object is present" carve-out was unsound: `{type:"object",$ref:"#/$defs/Foo", $defs:{Foo:{type:"array"}}}` parsed fine but no object value can satisfy both at runtime, leaving the model to loop until maxTurns. Updated docstring + test cases (replaced the accept-with-anchor case with a reject case for both anchored and well-formed $ref shapes — users wanting composition should inline at the root). 2. Redact `function_args` for structured_output in ToolCallEvent. The args ARE the user's structured payload (already emitted via stdout `result` / `structured_result`); recording them again as ordinary tool-call function_args duplicates that data into OTLP exports, QwenLogger, ui-telemetry, and the chat-recording UI event mirror — surfaces that can leak off-device. Replace with a stable `__redacted` placeholder so consumers still see the call happened (duration, success, decision metrics preserved) but the payload itself doesn't ride along. Two new uiTelemetry tests cover the redacted vs non-redacted paths. 3. Document and test that structured_output bypasses the --core-tools allowlist (same as agent / skill / exit_plan_mode / ask_user_question etc.). The synthetic tool only exists when --json-schema is set, so adding it to CORE_TOOLS would let `--core-tools read_file --json-schema X` silently drop the terminal contract and loop the model until maxTurns — bypass is intentional. Expanded the CORE_TOOLS docstring to enumerate the synthetic-tool exclusions and added a permission-manager test mirroring the pattern used for agent / skill / exit_plan_mode. * fix(cli): apply structured_output terminal handling to drain turns The synthetic structured_output tool is registered for the entire headless session, so it can be invoked from EITHER the main assistant-turn loop OR from a drain turn (queued cron-job / notification reply). The drain path (drainOneItem) was treating it like any other tool: execute, append the response back into itemMessages, keep going. The submitted args were never captured and no structured_result envelope was emitted, so a run that legitimately satisfied --json-schema mid-drain ended up failing the contract with "Model produced plain text..." anyway. Apply the same terminal handling to drain turns: - Hoist `structuredSubmission` to session scope so both paths write to one variable. - In `drainOneItem`, run the same pre-scan: when --json-schema is active and structured_output is in the batch, execute every structured_output in original order until one succeeds; suppress every non-structured sibling. Synthesise tool_results for any unexecuted tool_use the model emitted, mirroring the main path. - On capture, return early from drainOneItem so the drained item's inner while loop stops. - `drainLocalQueue` short-circuits when a captured submission is in flight, so subsequent queued items don't run. - The cron `checkCronDone` watches the same flag and stops the scheduler immediately on capture, releasing the surrounding `await new Promise(...)`. - The final holdback loop bails out on capture so monitor lifecycle doesn't extend past the structured submission. - After the holdback, before the existing failure / regular-success emit, emit the structured success envelope and return 0. Adds a focused unit test that drives the drain path end-to-end via a synchronously-fired monitor notification: main turn produces plain text, the drain reply calls structured_output, and the test asserts exit 0 + structured_result populated + no "Model produced plain text..." error. * fix(cli): address gpt-5.5 review follow-ups on --json-schema scaffolding Six review findings, six small fixes: 1. **Nested $ref incorrectly rejected.** `schemaRootAcceptsObject` recurses into anyOf/oneOf/allOf branches and used to apply the root-only $ref rejection at every level, blocking common composition shapes like `{anyOf:[{$ref:"#/$defs/Foo"},{type:"string"}]}`. Add an `isRoot=true` parameter; non-root recursion treats `$ref` as opaque and defers to Ajv at runtime. Tests cover nested refs in anyOf / oneOf / allOf. 2. **Inaccurate package-root export comment.** `core/src/index.ts` claimed `SyntheticOutputTool` was exported as a runtime value for the CLI's --json-schema flow, but the only construction is inside `Config.registerLazy` via a relative dynamic import — no value consumer reaches into `@qwen-code/qwen-code-core`. Revert to a type-only re-export so `SyntheticOutputTool` lines up with every other lazy-loaded tool class. 3. **Unused constructor parameter.** `SyntheticOutputTool` took `(_config: Config, schema)` but never read `_config`. Drop the parameter (and the corresponding pass-through at the registration call site) so readers don't wonder why a Config is being threaded through. 4. **Tool description claimed "exactly once".** The retry path explicitly tolerates multiple calls until one validates, so "Call this tool exactly once" is misleading to a model that tried twice. Reword to "Call this tool to deliver the final result; the first call with valid arguments ends the session" so the description matches the actual contract. 5. **Asymmetric shutdown on the structured-output success path.** The regular terminal path waits in a holdback loop until `hasUnfinalizedTasks()` is false; the structured-output path used to call `abortAll()` and flush immediately, dropping the matching `task_notification` for any agent whose natural handler hadn't yet enqueued it. Add a bounded holdback (capped at 500ms via STRUCTURED_SHUTDOWN_HOLDBACK_MS) — long enough for typical abort callbacks to enqueue, short enough that a hung agent can't block exit. 6. **gemini.tsx exit-code asymmetry.** `runNonInteractive` returns an explicit exit code, but `runNonInteractiveStreamJson` still reads `process.exitCode` after `runExitCleanup`. Currently safe because the yargs `.check` rejects --json-schema with stream-json input, but a future stream-json equivalent of structured output would need to plumb the exit code through the return value too. Document this in a comment so the constraint is visible at the call site. Plus: strengthen `synthesises tool_result for suppressed sibling calls when structured_output fails validation` to assert the failed structured_output's `functionResponse.response` carries the actual validation error string ("args invalid"), not the synthesised "Skipped:" prose — a regression that overwrote it would otherwise slip past the existing pairing assertion. * fix(cli): close --json-schema gaps surfaced in self-audit + review Five fixes layered onto the same robustness pass over the `--json-schema` flow: 1. **bare-mode registration** (`packages/core/src/config/config.ts`): `qwen --bare --json-schema X -p "..."` previously skipped the synthetic `structured_output` registration entirely (the registration block lives below the bare-mode early-return), so the model had no way to terminate and the run looped to `maxSessionTurns`. Register the synthetic tool inside the bare branch too. 2. **TTY interactive rejection** (`packages/cli/src/gemini.tsx`): `qwen --json-schema X` on a TTY with no `-p` and no piped stdin routes to `isInteractive=true` (priority-3 fallback) and would launch the TUI, where `structured_output` is just an inert tool that prints "accepted" and lets the chat continue. Parse-time gating can't catch this (stdin isn't probed yet at parse time), so reject at runtime before the UI launches; runs `runExitCleanup` first so MCP subprocesses get torn down. 3. **drain-turn structured-success flush** (`packages/cli/src/nonInteractiveCli.ts`): when a drain turn captures `structured_output`, `drainLocalQueue` returns early, leaving any items the drain didn't process in `localQueue`. The prior emit path then ran `registry.abortAll()` + `emitResult` without flushing — stream-json consumers saw `task_started` events without paired `task_notification`. Add the same 500ms holdback + `flushQueuedNotificationsToSdk` the main-turn structured-success path uses, so the two paths agree. 4. **ACP mutual-exclusion** (`packages/cli/src/config/config.ts`): `--acp` runs an independent `runAcpAgent` turn loop that doesn't honour the synthetic-tool terminal contract, so `--acp --json-schema X` would register the tool but never terminate. Add a yargs `.check` rejection covering both `--acp` and the deprecated `--experimental-acp` alias. 5. **max-turns + Skipped wording** (review comments #3198579251/#3198579389/#3198579567 from yiliang114): - `handleMaxTurnsExceededError` now appends a `--json-schema`- specific hint pointing at the common stuck-run causes (structured_output denied by `permissions.deny` / `--exclude-tools`, unsatisfiable schema, prompt didn't instruct the model). Without this, three different failures all surfaced as the same generic "increase maxSessionTurns" line. - The synthesised "Skipped:" tool_result for suppressed sibling calls drops the trailing "Re-issue this call in a separate turn if needed." sentence on the success path, where the session terminates immediately and no consumer (model or SDK) can act on the advice. Retry path keeps the sentence — the model is about to receive these parts and may legitimately re-issue. Tests cover each fix: bare-mode registration order, ACP / experimental- acp rejection (×2), `--json-schema` hint in both text and JSON max-turns output, and explicit Skipped-text assertions on the success and retry paths. * fix: address 9 self-qreview comments on --json-schema PR Folds the 9 Suggestion-level comments from the previous /qreview pass into code/test fixes. Each one is a real issue, but mostly defensive — none changes the user-visible happy path. **Refactors (F4/F5/F6 — code-quality)** - F4 `nonInteractiveCli.ts`: extract `SUPPRESSED_OUTPUT_SUCCESS` / `SUPPRESSED_OUTPUT_RETRY` module-level constants and a `suppressedOutputBody(structuredCaptured)` helper. Both the main-turn and drain-turn synthesis sites previously had a 4-way duplicated ternary; future wording changes can no longer drift between them. - F5 `nonInteractiveCli.ts`: extract `emitStructuredSuccess()` closure inside `runNonInteractive`. The "abortAll → bounded holdback → flush → finalize one-shot monitors → emitResult → return 0" terminal block is now defined once and called from both the main-turn and drain-turn success paths. `finalizeOneShotMonitors` is idempotent (`oneShotMonitorsFinalized` guard) so the unconditional invocation is safe even when the drain-turn already finalized monitors before reaching the helper. - F6 `core/config/config.ts`: extract `registerStructuredOutputIfRequested()` helper. The synthetic-tool registration block is no longer duplicated between the bare-mode early-return branch and the regular registration branch. **Tests (F7/F8/F9 — pin existing behaviour)** - F7 `nonInteractiveCli.test.ts`: new test "holds back for in-flight background tasks before emitting structured success" — flips `hasUnfinalizedTasks: true → false` mid-poll so the holdback `while` body actually executes; spies on `abortAll` and asserts ordering of `task_notification` (must precede the result envelope) and the bounded elapsed-time cap. None of the existing structured-output success tests entered this branch (they all pinned `hasUnfinalizedTasks: () => false`). - F8 `gemini.test.tsx`: new test "rejects --json-schema when running in interactive (TUI) mode" — pins the TUI guard at gemini.tsx:694, asserting the headless-only stderr message AND the exact ordering `writeStderrLine → runExitCleanup → process.exit(1)` so a future refactor can't swap any of those steps. - F9 `cli/config.test.ts`: pin the two previously-untested `--json-schema` mutual-exclusion branches: `-i`/`--prompt-interactive` and `--input-format stream-json`. The stream-json check is load-bearing — `gemini.tsx:768` explicitly relies on this rejection holding (the parse-time `process.exitCode ?? 0` plumbing in the stream-json branch is only safe because `--json-schema` can't reach it). **Behaviour fixes (F1/F2/F15 — privacy / security / correctness)** - F1 `core/core/geminiChat.ts`: redact `functionCall.args` for `structured_output` tool calls before passing them to `chatRecordingService.recordAssistantTurn`. Without this, the user's structured payload (already emitted on stdout via `result` / `structured_result`) was persisted verbatim to `<projectDir>/chats/<sessionId>.jsonl` and re-fed into model context on `--continue` / `--resume`, contradicting the privacy contract documented next to the existing `ToolCallEvent` redaction. Each validation-failure retry was also recorded. Now mirrors the same `__redacted` placeholder. Helper extracted as `redactStructuredOutputArgsForRecording` so it's unit-testable. - F2 `cli/config/config.ts`: `resolveJsonSchemaArg`'s `@path` reader now (a) `fs.statSync`s first to refuse non-regular files (FIFOs, character devices like `/dev/zero`, directories), (b) caps the schema file at 1 MiB so an attacker who can influence the path through a wrapping process can't OOM the run, and (c) on JSON parse failure for `@path` source emits a generic "content of <path> is not valid JSON" instead of echoing the SyntaxError — Node ≥18's SyntaxError embeds a ~10-char file-content prefix in its message, which would otherwise ride out on stderr through any wrapper that surfaces the error. Inline (non-`@path`) JSON keeps the SyntaxError detail because the user is the source. - F15 `core/tools/tool-registry.ts`: `registerTool` now also checks the lazy `factories` map for name collisions, not just the eager `tools` map. An MCP server registering a tool whose name shadows a built-in lazy factory (e.g. `structured_output`) now gets auto-qualified to `mcp__<server>__<name>`, instead of silently winning the resolution. The synthetic structured-output tool no longer needs renaming for the corner case to be safe. Targeted suite (13 changed-area test files): 883/886 pass — 3 pre-existing skips. Typecheck clean on both packages. * fix: address 3 deepseek-v4-pro qreview comments on --json-schema PR Three Suggestion-level comments from the latest /qreview pass. **N1 — `schemaRootAcceptsObject` skips `if/then/else`** (cli/config/config.ts): A schema like `{"if": true, "then": {"type": "string"}}` passed parse-time gating but is unsatisfiable for object-typed tool args at runtime — the model would loop until maxSessionTurns. Add a best-effort check for the two decidable shapes: - `if: true` → object MUST match `then`; if `then` excludes objects (boolean `false`, non-object `type`, etc.), reject at parse time. - `if: false` → object MUST match `else` (`true` if absent); same check. Object-schema `if` cases stay runtime-decidable and fall through to Ajv, matching the existing best-effort scope on `not`. 4 new test cases pin both reject and accept paths. **N2 — subagent registries register `structured_output` too** (core/config/config.ts, core/tools/agent/agent.ts, core/agents/backends/InProcessBackend.ts): `createApprovalModeOverride` and `buildSubagentContextOverride` rebuild the tool registry on a `Object.create(base)` config. `this.jsonSchema` propagates through the prototype chain, so `registerStructuredOutputIfRequested` was firing for every subagent registry rebuild — but only `runNonInteractive`'s main / drain loops detect a successful `structured_output` call as terminal. A subagent that called the tool would receive "Session will end now" and then keep running because its own loop has no terminator: wasted tokens, no structured payload on stdout. Add a `forSubAgent: true` option to `createToolRegistry` (alongside the existing `skipDiscovery`), and propagate it from both subagent rebuild sites. The structured-output registration helper short-circuits when the flag is set. Bare-mode init does NOT set the flag, preserving the F6 fix where `qwen --bare --json-schema X -p "..."` still gets the synthetic tool. New test asserts the registry rebuilt with `forSubAgent: true` registers READ_FILE / EDIT / SHELL but NOT STRUCTURED_OUTPUT. **N3 — TEXT-mode `structuredResult` not integration-tested** (nonInteractiveCli.test.ts): All 8 existing `--json-schema` tests pin `OutputFormat.JSON` or `STREAM_JSON`. TEXT (the default for `qwen -p ...`) has no integration coverage, so a regression in `BaseJsonOutputAdapter.buildResultMessage`'s `hasStructured ? JSON.stringify(structuredResult) : resultText` contract or in `JsonOutputAdapter.emitResult`'s text-mode `process.stdout.write(`${result}\n`)` path would only surface to plain `qwen -p` users. New test pins TEXT-mode behaviour: stdout is exactly `${JSON.stringify(structuredArgs)}\n` — no JSON envelope, no event log. Targeted suite (13 spec files): 945/948 pass — 3 pre-existing skips. Typecheck clean on both packages. * fix(cli): narrow `not` rejection in schemaRootAcceptsObject Address Critical review comment #3216123734. `schemaRootAcceptsObject`'s `not` handler previously rejected any schema whose `not.type` included `"object"`, regardless of what other constraints `not` had. That's a false positive for schemas where the extra constraints NARROW what `not` excludes: { "not": { "type": "object", "required": ["error"] } } excludes only objects with an `error` key — the value `{}` satisfies this schema fine, but the old check rejected it at parse time with "--json-schema root must accept object-typed values". Fix: only reject when `not` is exactly `{type: ...}` with no narrowing siblings (the unambiguous "every object is excluded" case). When other keywords are present (`required`, `properties`, `minProperties`, `enum`, etc.), defer to Ajv at runtime — same best-effort scope as the sibling `anyOf`/`oneOf`/`allOf` deep-content checks. 3 new test cases pin the fixed accept paths (`{not:{type:"object",required:[...]}}`, `{not:{type:"object",properties:...,required:[...]}}`, `{not:{type:"object",minProperties:1}}`). The existing reject test for bare `{not:{type:"object"}}` still passes. * refactor: dedupe structured_output handling per qreview C1/C2/C3 Three Suggestion-level review comments from the latest /qreview pass. **C1 — main-turn / drain-turn `structured_output` dispatch was duplicated ~120 lines** (`nonInteractiveCli.ts`) The two batch-handling sites had near-identical bodies (filter `structured_output` from the batch when `--json-schema` is active → iterate with `executeToolCall` → write to `structuredSubmission` on first valid call → synthesise tool_result events for suppressed siblings). The only meaningful difference was which `modelOverride` binding the loop wrote to (session-scoped `modelOverride` for the main turn vs per-drain-item `itemModelOverride`). Extracted `processToolCallBatch(batchRequests, setModelOverride)` defined inside `runNonInteractive`: - Closes over session-scoped state (`adapter`, `config`, `abortController`, `options`, `structuredSubmission`, `executeToolCall`, `handleToolError`, `suppressedOutputBody`, the progress-handler helpers). - Takes the `modelOverride` setter as the one call-site-specific parameter so the main turn binds to the session var and the drain binds to the per-item var. Main-turn body went from ~120 lines to a single call; drain-turn body likewise. Net file shrink ~80 lines, no behaviour change. All 42 existing structured-output tests still pass (including `stops executing remaining tool calls...`, `tries multiple structured_output calls in the same turn...`, `synthesises tool_result for suppressed sibling calls...`, `captures structured_output emitted from a drain-turn (queued notification)`). **C2 + C3 — `{__redacted: '…'}` placeholder duplicated in two files** (`telemetry/types.ts` + `core/geminiChat.ts`) The `ToolCallEvent` constructor (for telemetry surfaces — OTLP / QwenLogger / ui-telemetry / chat-recording UI event mirror) and `redactStructuredOutputArgsForRecording` (for the on-disk chat-recording JSONL) each had a verbatim copy of: { __redacted: 'structured_output payload (see stdout result)' } If the redaction wording (or the `__redacted` key, or the placeholder text) ever drifted between the two surfaces, the privacy contract would be subtly broken on one and not the other. Hoisted to `STRUCTURED_OUTPUT_REDACTED_ARGS` exported from `packages/core/src/tools/syntheticOutput.ts`, imported in both sites. The constant carries its rationale in a JSDoc block so future readers see both call sites at once. Targeted suite (13 spec files): 961/964 pass — 3 pre-existing skips. Typecheck clean on both packages. --------- Co-authored-by: wenshao <wenshao@U-K7F6PQY3-2157.local>	2026-05-11 14:21:55 +08:00
Shaojin Wen	e2f7661ef1	feat(cli): Ctrl+B promote keybind (#3831 PR-3 of 3) (#3969) ... * feat(cli): Ctrl+B promote keybind — wire UI to PR-2's promoteAbortController (#3831 PR-3 of 3) Final piece of the foreground → background promote feature. PR-1 (#3842) landed the `signal.reason` foundation; PR-2 (#3894) wired `shell.ts` to detect a `{ kind: 'background' }` abort, snapshot output, register a `BackgroundShellEntry`, and stash the promote `AbortController` on `TrackedExecutingToolCall`. This PR exposes the user-visible surface: pressing Ctrl+B during an in-flight foreground shell command transfers ownership to a background task the user can inspect via `/tasks` or stop via `task_stop`. ## Changes - `keyBindings.ts`: new `Command.PROMOTE_SHELL_TO_BACKGROUND` bound to `Ctrl+B`. JSDoc explains the no-shell-running no-op semantics. - `useReactToolScheduler.ts`: project `promoteAbortController` from the core's `ExecutingToolCall` through `TrackedExecutingToolCall` so the React layer (AppContainer keypress handler) can find it by callId without re-plumbing through the scheduler. - `AppContainer.tsx`: `handleGlobalKeypress` gains a `PROMOTE_SHELL_TO_BACKGROUND` branch that walks `pendingToolCallsRef.current` (the ref, not the destructured array — keeps the deps list stable so the handler isn't re-bound on every tool-call status update), finds the executing tool call with a defined `promoteAbortController`, calls `.abort({ kind: 'background' })`, and returns early. No-op when no foreground shell is executing — Ctrl+B then falls through to the input layer's existing cursor-left binding. - `keyboard-shortcuts.md`: documents Ctrl+B with explicit fall-through behavior so the conflict with the prompt-area cursor-left binding is intentional + understandable. ## Tests - `keyMatchers.test.ts` (+1): Ctrl+B positive / bare-b + meta+b + Ctrl+other negatives. - `AppContainer.test.tsx` (+2): - **Ctrl+B promotes** — pendingToolCalls includes an executing shell with a stubbed `AbortController` + spy; firing Ctrl+B asserts `abort({ kind: 'background' })` is called once. - **Ctrl+B no-op** — empty `pendingToolCalls` + Ctrl+B must NOT throw (pins the safety contract for the typing-mid-prompt case where the input layer's own Ctrl+B should still fire). - 37/37 keyMatchers + 58/58 AppContainer pass; tsc + ESLint clean. ## E2E (manual, PR description guidance) The unit / integration tests cover the keybind → abort wiring and the promote handler's downstream behavior (PR-2's tests). Real-PTY E2E is intentionally manual since headless test infrastructure doesn't drive a real shell child + Ctrl+B keystroke; documented in the PR description checklist. Closes the 3-PR sequence for #3831 (Phase D part b of #3634). * fix(cli): #3969 review wave — broadcast comment + debug log + redundancy 5 #3969 review threads addressed: - **AppContainer.tsx Ctrl+B handler**: documented the KeypressContext.broadcast caveat (after `return`, the same Ctrl+B is still dispatched to text-buffer cursor-left + DebugProfiler; visible cursor-left side effect is cosmetic) so future readers understand why the prompt cursor moves on a successful promote. Added `debugLogger.debug` calls on both branches (matched callId on success; streamingState + pendingToolCalls.length on no-op fall-through) so "Ctrl+B doesn't work" reports are debuggable. - **useReactToolScheduler.ts TrackedExecutingToolCall**: dropped the redundant `pid?` and `promoteAbortController?` declarations — both come through the `& ExecutingToolCall` intersection unchanged. Fixed the JSDoc that wrote `{ kind: 'background', shellId }`: callers don't generate `shellId` (it's optional on the abort-reason union and `handlePromotedForeground` produces it downstream). The corresponding executing branch in `toolCallsUpdateHandler` no longer projects pid / promoteAbortController explicitly — `...coreTc` already spreads them; the explicit-undefined clearing in the non-executing branch is also dropped (those fields aren't on coreTc when status !== 'executing', so `...coreTc` doesn't carry them). - **AppContainer.test.tsx**: replaced two `as unknown as Key` double-casts with direct `: Key` annotations on the literal — the object already conforms to the Key interface, double-cast was bypassing type safety needlessly. Tests: 37/37 keyMatchers + 58/58 AppContainer pass; tsc + ESLint clean. No behavior change beyond the new debug log lines. * fix(cli): #3969 wave — tool-name guard + non-shell test + defensive clear 3 #3969 review threads addressed; 1 deferred: - AppContainer.tsx: Ctrl+B `find()` predicate now also checks `tc.request.name === ToolNames.SHELL` before matching the executing tool call. Defense-in-depth — today only the shell tool wires `promoteAbortController`, but a future copy-paste / type confusion that adds the property to a non-shell tool would otherwise let Ctrl+B mistakenly fire `abort({kind:'background'})` on a tool whose service has no promote-handoff handler. - useReactToolScheduler.ts: re-added explicit `pid: undefined` and `promoteAbortController: undefined` to the non-executing return. Previously dropped on the assumption that `...coreTc` doesn't carry these fields when the status isn't `executing` — true today, but the explicit clearing is defense-in-depth against a future core change that adds either field to a non-executing status type (would surface as a stuck PID display or a Ctrl+B handler that matches a no-longer-executing tool call). - AppContainer.test.tsx: replaced the placeholder "no-op when no pending tool calls" framing on the empty-array case (it does exercise the `executing-status` predicate but NOT the tool-name guard) with TWO tests: 1. existing empty-array no-throw test (renamed for clarity) 2. NEW: executing non-shell tool with a hostile-shape `promoteAbortController` — asserts `abortSpy` is NOT called. This is the regression test for the new tool-name guard above. Tests: 61/61 AppContainer.test.tsx pass; tsc + ESLint clean. Deferred to follow-up (replied + tracked): - `debugLogger.debug` is file-only; success-path "agent unblocks + next message says 'promoted to bg_xxx'" is the user-visible signal. Adding a synthetic history item or stderr line for the gap between keypress and agent message conflicts with Ink rendering and is better as a focused UX PR. * test(cli): pin inheritance of pid + promoteAbortController via type assertions #3969 review: the earlier "redundant declaration" review removed the explicit `pid?: number` and `promoteAbortController?: AbortController` from `TrackedExecutingToolCall`, relying on the `& ExecutingToolCall` intersection to inherit them. Current review flags the type-safety regression: if core renames or removes either field, the React-side build won't catch it locally — Ctrl+B handler silently breaks at runtime. Compromise: keep the type minimal (no re-declaration noise the prior review flagged) but add compile-time `extends keyof ExecutingToolCall` assertions that fail loudly + locally if either field disappears. The assertions are evaluated at compile time and zero-cost at runtime; the dummy `const` pins them so they aren't dead code. 61/61 AppContainer tests pass; tsc clean.	2026-05-11 14:03:38 +08:00

Shaojin Wen	b949ae070c	feat(tools): defer low-frequency built-in tools to reduce initial prompt size (#4022) ... * feat(tools): defer low-frequency built-in tools to reduce initial prompt size Mark Monitor, SendMessage, Skill, TaskStop, TodoWrite, and WebFetch as shouldDefer=true so their full schemas are excluded from the initial function-declaration list. The model discovers them on demand via ToolSearch, aligning with Claude Code's deferral strategy for infrequently used tools. * fix(tools): don't defer TodoWrite/Skill — they're required by the system prompt TodoWrite is mandated as high-frequency by the core system prompt ("Use VERY frequently", "IMPORTANT: Always use the TODO_WRITE tool to plan and track tasks throughout the conversation"). Deferring it forces a ToolSearch round-trip before every required call, adding latency and hurting prompt compliance. SkillTool's full description carries the dynamically generated <available_skills> listing and the BLOCKING invocation rules ("invoke the relevant Skill tool BEFORE generating any other response"). The deferred-tool summary truncates this, so the model loses both the list of skills and the activation contract from the initial prompt. Keep Monitor / SendMessage / TaskStop / WebFetch deferred — those are genuinely infrequent and have no system-prompt requirement.	2026-05-11 11:40:13 +08:00

Gordon Lam	464e4cf343	feat(core): write runtime.json sidecar for active sessions (#3714) ... * feat(core): write runtime.json sidecar for active sessions Port kimi-cli PR #2082 part 1 to qwen-code. On interactive session start, atomically write a small JSON sidecar at <projectDir>/chats/<sessionId>.runtime.json recording the (pid, session_id, work_dir, hostname, started_at, qwen_version) tuple. External tools (terminal multiplexers, IDE integrations, status daemons) can map a running PID to its session id and work dir without parsing argv. Write is best-effort: a read-only filesystem must not block UI startup. OS process title (was #3713) and dynamic OSC tab title (kimi #2083) remain out of scope. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(core): refresh runtime.json on same-PID session swap Config.startNewSession() reassigns this.sessionId in the same process, which is reached by /clear, /reset, /new and /resume. Previously the old <oldId>.runtime.json was left behind, falsely claiming the still- live PID for a session no longer being served, and no new sidecar was written for the incoming session. Centralize the swap by clearing the old sidecar and writing a fresh one for the new session id from inside startNewSession itself, so all same-PID transitions are covered. The refresh runs as a fire-and- forget best-effort; failures must not block the session switch. Mirrors the post-merge Codex P1 fix on kimi-cli PR #2082 (the source of the runtime.json sidecar pattern this PR ports). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(core): only refresh runtime.json when this process owns it Mirrors kimi-cli PR #2082 commit e237951f (Codex P1 r3158754463): a short-lived non-interactive invocation (qwen --prompt, ACP, etc.) that runs `/clear` would otherwise call `Config.startNewSession()`, delete a concurrent shell's runtime.json sidecar (same outgoing session id), and never write a replacement — leaving the shell discoverable to nobody. Add a `runtimeStatusEnabled` flag on Config, flipped on by the interactive UI bootstrap immediately after the first successful sidecar write, and gate the swap-time refresh in `startNewSession()` on it. Non-interactive entry points never reach the bootstrap, so they won't touch sibling sidecars. Kimi later reverted the equivalent `write only from shell mode` guard (commit 7083975a) in favor of writing from every long-lived mode, but qwen's wire point is already interactive-only, so the narrower guard is the right shape here.
