- Settings modal on project list page for OpenAI, Anthropic, OpenRouter, Gemini, Semantic Scholar keys
- Keys stored in userData/api-keys.json, masked by default with show/hide toggle
- S2 API key passed to MCP server via .lattex-mcp.json to avoid rate limits

The resolve-thread socket event was only handled in ReviewPanel's
useEffect, but ReviewPanel is conditionally mounted (only when visible).
When Claude Code resolves a comment via MCP with the panel hidden, the
resolvedThreadIds store was never updated, so the editor highlight
persisted until the user opened the Review panel.

Fix: add a comments:event listener in App.tsx (always mounted) that
updates resolvedThreadIds for resolve/reopen/delete-thread events.

- Online users: click "N online" badge to see user names with cursor colors
- MCP get_online_users tool: main process tracks users in .lattex-online-users.json
- CLAUDE.md: show current user's Overleaf name (fetched from /user/settings)
- CLAUDE.md: mandatory first steps with MUST/NEVER language at top of file
- claude-workspace/ directory: untracked scratch space for Claude Code experiments
- chokidar + bridge skip claude-workspace/ to prevent syncing to Overleaf

- Fix .bib (and other non-active tab) edits disappearing: call otLeaveDoc
  on tab switch so bridge takes back OT ownership; release .bib pre-loads
  immediately after reading content for citation autocomplete
- Always update lastKnownContent in processDocChange for editor docs to
  prevent stale state accumulation
- Flush pending OT ops in OverleafDocSync.destroy() before tab switch
- Add three-way merge in replaceContent to preserve concurrent remote edits
- Wire MCP compile to UI: file-based signal between MCP server and Electron
  main process, with compile animation and PDF refresh in renderer
- Add CLSI flush before compile to prevent stale cached results
- Add OT error recovery: re-join doc and re-apply disk changes on otUpdateError
- Add bridge reconnect handling: reset OtClient on docRejoined for non-editor docs
- Add compile concurrency lock to prevent duplicate compiles
- removeEditorDoc compares disk vs server content to catch in-flight ops

setPdfPath with the same path didn't trigger re-render. Added pdfVersion
counter that increments on every setPdfPath call, used as dependency in
PdfViewer's renderPdf to force reload regardless of path equality.

- Zoom centers on mouse cursor position (scroll adjustment)
- Two-phase render: instant CSS transform + debounced canvas re-render
- No blank flash: old canvases kept until new render completes atomically
- No bounce-back: track renderedScale separately from renderScale
- Inner wrapper div for CSS transform (container stays as scroll viewport)

- synctex.gz CDN returns 503; use Overleaf web proxy URL with session cookie
- Normalize synctex paths (collapse /./ segments)
- Pass session cookie to all compile artifact downloads
- Smooth editor zoom: continuous delta, debounced remeasure
