Adds a persisted Chat/Research mode selector, durable progress timeline, cancellation, navigation restoration, and a rendered/downloadable Markdown report experience.
Research state loads in parallel with thread state, and unsupported attachments are rejected instead of silently ignored.
Validation: 2 focused web tests, Biome, and diff checks.
## What changed
- Added a chat-shell-level file drag/drop target so the whole chat area, including the conversation area, shows the drop overlay and accepts files.
- Disabled the nested composer drop handler for the sidebar chat path to avoid duplicate drops or stuck overlay state.
- Kept the existing local input drop behavior available for other ChatInput usages like the home composer.
- Added attachment draft/shared types and validation in components/chat/attachments.ts.
- Added paperclip upload UI to Nova composer with file chips, size/status, remove, retry, and per-file Save / Chat only toggle.
- Wired uploads before send to /chat/attachments, then sends returned attachment references in chat message metadata.
- Preserved attachment metadata when loading threads and rendered attachment chips on user messages.
- Added attachment support from the home composer into the full chat view.
- Extended chat analytics with attachment counts.

- ensured responsiveness
Consolidate login routes, add animated tool context visualization on the hero panel, and polish loading states across onboarding, settings, and workspace bootstrap.
Nova mobile pass
- viewport: viewportFit cover for iOS safe-area-inset
- safe-area utilities (pb-safe, pt-safe, bottom-safe-5, scroll-fade-x) in globals.css
- chat FAB pinned above iPhone home indicator; chat sidebar widths responsive across sm/md/lg with min() clamps
- chat input CoT panel max-h capped via min(60dvh, 420px)
- header tab strip swapped from visible scrollbar to scroll-fade-x mask + snap-x
- nova empty state uses svh on mobile, dvh from sm up
Add-memory modal rebuilt for mobile
- mobile shell switched from fullscreen Dialog to vaul Drawer at 85svh with swipe-down dismissal and scaled background
- in-modal header removed; tabs moved to the bottom of the sheet for thumb reach
- four tab compactLabels: Note, Links, Files, Connections
- desktop tabs now render only when !isMobile (no DOM duplication)
- note/link content state lifted to parent so switching tabs preserves typed input
- NoteContent snapshots initialContent via lazy useState so the editor isn't reset on every keystroke
- shared Drawer base uses rounded-t-xl
- removed legacy pt-4 on tab content for mobile
Connections — replace expiresAt with sync-run health
- new useConnectionHealth hook reads the latest sync run and matches auth-failure patterns; backend errorKind field still needed (TODO)
- regex tightened so 401/403 require co-occurring auth/token/grant context; refresh_token requires expired/revoked/invalid/missing qualifier
- badge label changed Disconnected -> Needs reauth
- Reconnect button replaces the sync action when needsReauth, kicks off the same OAuth flow
- per-row reconnect tracking via mutation.variables instead of a single shared id (no race when multiple rows clicked)
- fallback toast when authLink is missing so the spinner can't get stuck
- sync history panel timeline capped at max-h-260 with internal scroll
- useSyncRuns no longer refetches on mount; cache (30s) actually applies, cutting N requests per modal open
