Lattice documentation

Lattice is a local-first LaTeX and Markdown writing environment for macOS: a Tauri 2 (Rust) shell around a React 19 / TypeScript / Vite 8 frontend, with a bundled AI-agent sidecar (Synara) and Overleaf sync.

Start here

Read in this order if you are new:

  1. ../README.md — what the product is, how to install and run it.
  2. ../CONTRIBUTING.md — how to set up a dev environment and get a change merged.
  3. architecture.md — the processes and windows (Rust host, WKWebView workspace window, Node sidecar) and what crosses each boundary; the Rust command surface; the on-disk .research/ layout; the bundle and startup constraints; the design-system contract.
  4. codebase-map.md — "if you want to change X, start at Y"; how src/ is split into domain directories and what stays at its root; one line per Rust module; the files that matter; the known rough edges.
  5. Then whichever subsystem doc below matches what you are touching.

../CLAUDE.md is the always-loaded steering for AI coding agents: a few non-obvious gotchas plus pointers into these documents, starting with agent-validation.md. Where it disagrees with architecture.md, the longer document usually has the fuller story — but do not treat a path:line citation as a tiebreaker on its own. Line numbers in architecture.md and codebase-map.md are spot-checked pointers, not guarantees, and they drift with every commit; the durable anchors are file names, function names and constant names. When it matters, grep.

Index

Document What it covers Status
architecture.md Process boundaries, the Rust backend, the on-disk data model, performance/bundle constraints, the design-system contract, the pnpm check gate. Current
codebase-map.md Where to start for each feature area; directory inventory; domain decomposition of src/; the src-tauri/src/ modules; the files that matter; known rough edges. Current
design-system.md Typography, density, palette and spacing decisions — the reasoning behind the tokens that src/styles/tokens.test.ts enforces. Current
synara-runtime.md The bundled agent sidecar: how to work without building it, the runtime boundary, the tool catalog the model actually sees, staging and pruning, and the upstream-sync procedure for a pin change. Current. Its tool-count figures are dated measurements — re-run the commands it gives rather than quoting them.
synara-fork-ledger.md What each Synara pin brought into the fork, the fork's size against upstream, and how the embedded panels behave against the current pin. Current. Each pin change updates it; its fork-size figures are dated measurements.
project-history-architecture.md ADR 0001: why Project History is a merged semantic timeline over two stores (Lattice transactions in .research/history + agent turn checkpoints) rather than a third recovery format. Accepted, and matches the code (history schema v2, forward-only restores linked by undoOf).
markdown-structured-crdt-evaluation.md ADR 0002: evaluation of a native structured-Markdown CRDT (Y.XmlFragment) as a replacement for canonical Y.Text("content"). Decision: NO-GO. Historical. The prototype it evaluated (src/editor/markdown/markdown-structured-crdt-prototype.ts) was imported by nothing except its own test and has been deleted; the Y.Text model it compared against was removed with Lattice Shares.
performance.md How to measure (the pnpm perf:bench interaction benchmark CI gates on, the lattice-perf dev-app probe, the real-window lab), the React Compiler status and open directions. Current
performance-history.md Every dated performance investigation, oldest first: what was slow, what changed, and the before/after tables pnpm perf:evidence recomputes. Historical log. Its numbers are dated measurements; re-measure before quoting.
agent-validation.md For coding agents: proving a change, reading a failed check, the checkpoint/resume recipe, reading report evidence, and the review trigger. Current
driving-the-app.md Seeing the app run: the mock-backend page for UI work and screenshots, the website's demo, the browser-hosted real app, and the real-window measurement lab (scripts/perf-lab.mjs), with the latticetest isolation rules. Current
logging.md Where lattice.log lives, the one-line-per-operation wide events and their fields, reading them for a bug report, LATTICE_LOG for more detail, adding an event. Current
overleaf-protocol.md The Overleaf bridge: provenance ledger with pinned upstream commits, the license boundary, why the transport is Socket.IO 0.9, the protocol and data invariants, the opt-in cloud tests, and what a wire-level change has to come with. Current. Read it before touching src/overleaf/ or src-tauri/src/overleaf*.rs.
visual-editor-spec.md The clean-room behavioral specification of the visual Markdown editor, each requirement citing the Lattice test or format it came from, plus the design and status of Lattice's own engine (src/editor/markdown/engine/), which replaced the vendored Open Knowledge editor. Frozen. Kept as the clean-room record behind the Apache-2.0 relicense and no longer edited to track the code; its Derived from: citations resolve at commit c44f285a, and retired requirements are marked obsolete in place.
clean-room-provenance.md The record of the similarity (Dolos, copydetect) and provenance (ScanCode) scans run before the Apache-2.0 relicense: tools, settings, reference commit, scope, scores and the clean-room rules the rebuild followed. Current. Historical record of the scans that cleared the relicense.
adr/ Architecture decision records — dated reasoning, including decisions that have expired. Index at adr/README.md; adr/0003 archives the Overleaf stage baseline and its lapsed contribution freeze.
release-process.md How a release is cut: scripts/bump-version.mjs, the tag push, what .github/workflows/release.yml builds, signs and publishes, and why GitHub Releases is the changelog. macOS Apple Silicon only. Current

overleaf-integration-baseline.md was split. Its durable half — provenance, license boundary, protocol invariants, the upstream-reference procedure — is now overleaf-protocol.md. Its dated half — the Stage -1 framing, the f7515eca baseline, the test and lint snapshots, and a protected-file freeze that lapsed without ever being announced — is archived as adr/0003-overleaf-stage-baseline.md.

tldraw-integration-plan.md was removed: it was a pre-implementation plan for work that has since shipped (the whiteboard is src/editor/board/board-editor.tsx + src/editor/board/board-store.ts), and its central file reference, src/tldraw-yjs-bridge.ts, never existed. tldraw's licensing — the one part of it that was still live — is covered by ../THIRD_PARTY_NOTICES.md, which is more current than the plan was (the plan described SDK 4.x; the repo pins tldraw@5.2.5).
