On launch the home page checks the latest GitHub release; when a newer
version exists a bottom-right card offers Download (streams the right
installer for the platform into ~/Downloads and opens it), Later, or
Skip this version (remembered). Unsigned app rules out silent
auto-update on macOS, so installation stays a manual replace.

The project list is now a persistent home tab; each opened project runs
in its own WebContentsView tab below a 38px tab strip (hidden when only
home is open). Background tabs stay fully live (sync, collab, terminals).

Main process: per-project singletons (socket, sync bridge, compilation
manager, MCP state, compile watcher) become per-tab ProjectSession
objects keyed by webContents.id; PTYs are scoped per webContents.
Hardened against races found in review: concurrent ot:connect dedupe,
teardown/reopen serialization on the shared sync dir, destroyed-window
guards on all bridge sends, real logout that closes project tabs.

Renderer: tabs strip in the home renderer (wt-* classes, distinct from
the editor's .tab-bar file tabs), project tabs boot from ?projectId= and
connect straight into the editor; Back closes the tab.

Workspace browser:
- The left panel gains a Project/Workspace toggle; the Workspace view
  browses the agent scratch space (claude-workspace/, never synced)
- Open/edit workspace text files in the editor with debounced auto-save
  (flushed on tab switch); binaries open with the system default app
- Import to Project copies a workspace file/folder into the project root
  where the sync bridge picks it up and creates it on Overleaf
  (collision-safe: falls back to a -imported suffix)
- New file/folder, rename, delete, reveal in Finder, drag-drop into the
  workspace, 5s auto-refresh while visible

OpenAlex search (MCP):
- New search_openalex tool: broad OpenAlex coverage with an explicit
  citation-authority policy — BibTeX is cross-checked against Semantic
  Scholar (by DOI, then by exact title, since OpenAlex DOIs can point at
  mirrors); entries not found on S2 are flagged "OpenAlex only" with
  instructions to verify via web search before citing
- Tool description, agent guide, permission allowlist, and README updated

Uses the Overleaf open-source code as golden reference throughout.

Project dashboard (official /tag + /project endpoints):
- Sidebar filters (all/yours/shared/archived/trashed) with the web
  client's exact filtering predicates
- Tags: create/edit/delete with the official preset palette, per-row
  chips, bulk add/remove, uncategorized view
- Archive/trash/restore/delete-forever/leave, rename, copy, zip download,
  multi-select bulk actions (parallelized)

Editor:
- Remote cursors rewritten as a layer() overlay ported from Overleaf's
  cursor-highlights — no more inline widgets disturbing line wrapping,
  cursor motion, or IME composition
- Autocomplete ported from Overleaf's completion system: official
  top-hundred snippet data, environment templates, package/class/bib
  style data (verbatim, AGPL), project-wide \ref and \cite completion,
  package commands via the official /project/:id/metadata endpoint,
  brace-aware apply behavior, official keymap precedence
- Fixed completion popup keybindings (Enter/arrows previously fell
  through to the default keymap) and dead Enter/Backspace handlers in
  latexClosing

File sync reliability:
- Two-tier compile-artifact detection: pure build noise is ignored,
  while pdf/docx/gz/bbl sync unless there is concrete local-compile
  evidence — agent-generated figure PDFs now sync (previously all PDFs
  were blanket-ignored)
- Local compile outputs are registered with the bridge so nested-root
  projects don't upload the root PDF as junk
- Upload retry with exponential backoff and permanent-failure parking,
  CSRF refresh with session validation and single-flight guard,
  periodic orphan rescan, sync status surfaced in the status bar
- Official textExtensions list (plus legacy extras) for doc-vs-file
  classification

- 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

- 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

- In-file search: Cmd+F opens CodeMirror search panel with themed styling
- Multi-file search: Cmd+Shift+F or toolbar button opens project-wide search
- PDF text search: Cmd+F on PDF or search button to find text in PDF
- SyncTeX forward search: Cmd+Enter jumps from editor cursor to PDF position

- Exclude CLAUDE.md from sync (move to .claude/ dotfile dir, clean up root copy)
- Add Ctrl+wheel font zoom for editor (capture phase, disable Electron built-in zoom)
- Load cached PDF on project connect (avoid recompile to see last PDF)
- Add synctex debug logging for PDF↔source navigation troubleshooting
- Fix .claude/ dir creation order (mkdir before write)

The root cause of server compile failures was that output.pdf was being
saved into the synced project directory, causing FileSyncBridge to upload
it back to Overleaf as a project file. CLSI then failed because it found
an existing output.pdf blocking its compilation output.

Changes:
- Save compile artifacts (PDF, synctex.gz) to .build/ subdirectory instead
  of the synced project root — .build is a dotfile dir ignored by chokidar
- Add pdf/pdfxref/stderr/stdout/chktex to FileSyncBridge ignore patterns
- Add rootResourcePath to compile request body (matches Overleaf web client)
- Implement PDF download with fallback via direct build ID URL construction
- Add server compile handler, compile dropdown menu, PDF save button
- Fix resolved comment highlight flash on startup (null initial state)
- Fix EPIPE crash on startup when stdout/stderr is closed
- Fix synctex inverse search to use relative paths via OT doc join
