lattex.git/src/main/overleafSocket.ts, branch v0.3.2

Real-time comment sync, MCP server expansion, multi-tab terminal, UI fixes

2026-03-15T06:57:17+00:00

- Fix Socket.IO v0.9 ack parser to handle acks without data (6:::N format),
  fixing comment creation stuck at "sending"
- Rewrite comment sync to use local state updates from socket events
  (new-comment, resolve-thread, reopen-thread, delete-thread, edit-message,
  delete-message) instead of REST re-fetches — instant UI updates
- Optimistic updates for all comment actions (resolve, reopen, delete, reply, edit)
- Fetch threads + contexts on project connect so editor highlights are correct
  from startup, not only when review panel is opened
- Add comment context to store immediately after creation for instant highlight
- Rename MCP server from overleaf-comments to lattex, add 6 new tools:
  reopen_comment, delete_comment, get_chat_messages, send_chat_message,
  list_project_files, compile_latex — all auto-granted permissions
- Refactor terminal from fixed Terminal/Claude tabs to dynamic multi-tab with
  bottom tab bar and unlimited new terminal creation
- Fix chat panel layout overflow pushing other components

Fix Claude Code → Overleaf sync: remove hash from applyOtUpdate, fix OT bugs

2026-03-13T23:46:46+00:00

Root cause: SHA-1 hash sent with applyOtUpdate didn't match Overleaf's
server-side computation, causing "Invalid hash" error, disconnect, and
rollback of all synced changes.

- Remove hash field from applyOtUpdate to skip server-side hash check
- Switch applyOtUpdate from fire-and-forget to emitWithAck for reliable ack
- Fix getOldDoc bug: save base doc when changes start accumulating instead
  of incorrectly using current doc (caused wrong delete ops)
- Fix ack handler: only ack when no 'op' field (was acking remote ops too)
- Await fileSyncBridge.start() instead of fire-and-forget
- Add joinDoc retry logic for transient joinLeaveEpoch mismatch errors
- Clear pending ack callbacks on WebSocket close to prevent timeout errors
- Add otUpdateError logging for server-side rejections
- Add file-based bridge logging for debugging sync issues

  text via decodeURIComponent(escape()), matching Overleaf's client implementation
- Remove hacky byte-offset position remapping from index.ts
- Add pinch-to-zoom on PDF viewer

Add bidirectional file sync, OT system, comments, and real-time collaboration

- OT state machine, transform functions, and CM6 adapter for collaborative editing
- Comment system with highlights, tooltips, and review panel
- Project list, file tree management, and socket-based compilation
- 3-layer loop prevention (write guards, content equality, debounce)
