- Normalize watcher paths to forward slashes (Windows events use
  backslashes; all sync maps are '/'-keyed), path.delimiter for
  PATH/TEXINPUTS, dirname() instead of '/'-substring splits, bridge log
  in os.tmpdir()
- Platform-aware TeX search paths (TeX Live / MiKTeX on Windows),
  terminal shell default (COMSPEC/powershell), native window frame off
  macOS
- electron-builder: NSIS target + win icon + GitHub publish provider
- GitHub Actions workflow builds the Windows installer on tag push
  (node-pty needs MSVC — cannot cross-compile from macOS) and attaches
  it to the release

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

- Write AGENTS.md (the cross-tool agent-instructions standard) at the
  project root alongside .claude/CLAUDE.md, generated from one guide;
  includes an Agent Setup section with the project-specific Codex MCP
  registration command. AGENTS.md is excluded from Overleaf sync.
- MCP server resolves the project directory from its own script location
  when cwd doesn't contain the state file, so clients that launch MCP
  servers from a global config (Codex) work without special setup
- Terminal: swallow the duplicate compositionend commit when switching
  input sources mid-composition (xterm finalizes on the keydown and then
  again on compositionend, sending pinyin text twice)
- Don't render our own colored overlay cursor — the native caret already
  marks our position; overlay cursors are collaborators-only (web parity)

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

The server broadcasts otUpdateApplied (with ops) to ALL clients including
the sender. Our bridge was treating its own echoed ops as remote ops and
re-applying them, causing text duplication (e.g. "simulatorimulator").

Rewrite OT handling to match Overleaf's ShareJS _onMessage pattern:
- ACK = no ops OR meta.source matches our publicId (own echo)
- REMOTE = ops from a different source
- ACK path calls onAck() without re-applying ops
- OtClient silently drops duplicate acks in synchronized state
- OtClient drops stale remote ops (version < current)
- Remove pendingEchos counter in favor of meta.source detection

Also: refresh MCP comment contexts on new-comment/delete-thread events,
add Overleaf reference repo to .gitignore.

- 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
