Blocking (review id 2514):
- [security] Forbid symlinks in vaults. ensureServable now sets
core.symlinks=false in each vault's local git config (a pushed symlink is
checked out as a plain file, never a real link), and the engine cycle wraps
every read/write/mkdir in an lstat/realpath guard (new path-guard.ts) that
refuses a path that is — or traverses — a symlink, or whose realpath escapes
the vault root. Prevents a writer from publishing /etc/passwd or the server
.env, or writing outside the vault. Adds unit tests (path-guard.test.ts) +
a read-guard integration test (cycle.test.ts) + real lstat/realpath in the
roundtrip integration test.
- [simplification] Delete dead lib/diff.ts + test/diff.test.ts and drop the
now-unused @fellow/prosemirror-recreate-transform dependency.
- [documentation] Add a CHANGELOG [Unreleased] → Added entry for git-sync.
Warnings:
- [test-coverage] Cover the CREATE-branch conflict-markers guard (a new .md with
markers and no gitmost_id is recorded as a create failure, never created).
Suggestions:
- [stability] Bound each `git config` in ensureServable with a timeout.
- [authz] Trigger endpoint resolves spaceId workspace-scoped and 404s a foreign
space before any vault directory is created.
- [stability] Attribute git-initiated moves to the service account
(lastUpdatedById), via an optional actor param on PageService.movePage.
- [documentation] Document the per-space autoMergeConflicts toggle in AGENTS.md.
- [test-coverage] Cover the unterminated `:::` callout fence fallback.
- [simplification] Move test-only roundtrip-helpers.ts out of src/ into test/.
Architecture:
- Move the Yjs/ProseMirror merge primitives (yjs-body-merge, three-way-merge,
lcs + specs) into collaboration/merge/, breaking the collaboration →
integrations/git-sync dependency cycle this PR introduced.
- Port the schema-surface drift gate to packages/mcp (the mcp schema mirror had
none); pins 52 entries.
Deferred (with rationale in the review thread): the incremental-pull perf
warning (correctness-neutral; needs a high-water-mark design + its own tests on
the data-loss-critical path) and the redis-sync rolling-deploy mixed-version
edge (the deficient behavior is in already-released old-instance code; the new
code is correct on both sides; impact is a transient rollout-window artifact).

Coder↔reviewer design loop (9 rounds, reviewer verdict: exhaustive) produced
92 specs; implemented +123 tests (465 -> 588 passing). The new round-trip
coverage exposed three genuine data-loss bugs in the Markdown<->ProseMirror
converter, all now FIXED (round-trip is lossless for these):
1. pageBreak was lost on export (no converter case -> rendered to "" and the
node vanished). Now emits <div data-type="pageBreak"></div>, which the schema
parses back -> round-trips.
2. A block image between blocks left an empty <p> artifact after import-hoisting,
producing a phantom blank-gap diff on every sync. markdownToProseMirror now
strips content-less paragraphs after generateJSON — with a schema-validity
guard that keeps the obligatory single empty paragraph in `content: "block+"`
containers (tableCell/tableHeader/blockquote/column/callout/doc), so empty
cells/quotes never become an invalid `content: []`.
3. The `code` mark combined with another mark was not byte-stable (emitted nested
HTML that the schema's `code` `excludes:"_"` collapsed on import). The
converter now emits code-only when `code` co-occurs, matching the editor.
New coverage spans media/diagram/details/columns/math/mention attribute
round-trips, converter emission branches, git error paths, and engine decision
branches. A dedicated test pins the empty-container schema validity (the review
catch on the bug-2 fix).

First step of docs/git-sync-plan.md. New workspace package @docmost/git-sync
vendoring the PURE parts from docmost-sync (HEAD b03eb35):
- lib: markdown-converter, markdown-document, canonicalize, docmost-schema,
node-ops, diff, and an extracted markdown-to-prosemirror (only the pure
marked->HTML->generateJSON path from upstream collaboration.ts; no websocket).
- engine (pure, no IO): reconcile, layout, sanitize, stabilize, loop-guard.
Ported the upstream pure-module + round-trip corpus tests (vitest): 314 pass,
3 expected upstream known-limitation fails. tsc clean. No server wiring yet.
docmost-schema inlines getStyleProperty (as packages/mcp does — @tiptap/core
3.20.4 doesn't export it). IO engine (pull/push/git/settings) deferred to later
Phase A/B steps; the editor-ext idempotency gate (plan §13.1) is the next step.
