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).

The implementation spec docs/git-sync-plan.md was removed as completed, but ~44
code comments still cited it as "plan §N". Strip those citations (comments only),
keeping each comment grammatical. The vendored engine's own "SPEC §N" references
point at a different, still-present spec and are left untouched.

Fixes found by the live pull/push e2e:
- CRITICAL: driveCycle never checked out the 'docmost' branch before
applyPullActions, so Docmost content was written straight onto 'main',
clobbering local file edits before push could diff them. Now checkout
'docmost' before pull (applyPullActions commits there then checks out main +
merges) — mirrors the engine's pull main(). Round-trip now works both ways.
- add an unresolved-merge guard (SPEC §9): skip the cycle if the vault is
mid-merge instead of failing on checkout.
- SAFETY: enabledSpaces() is now STRICT opt-in — only spaces with
settings.gitSync.enabled===true; removed the all-spaces fallback that synced
every space (incl. a 92-page one) the moment GIT_SYNC_ENABLED flipped.
- SAFETY: per-cycle delete cap (GIT_SYNC_MAX_DELETES_PER_CYCLE, default 5):
dry-run the push, and if planned deletes exceed the cap, run the apply with
deletePage neutralized — phantom absence-deletions from a non-convergent vault
can't soft-delete real pages. Fails safe if the dry-run throws.
- fix manual trigger: TriggerGitSyncDto.spaceId needs @IsUUID or the global
whitelist ValidationPipe strips it (arrived undefined -> vault 'undefined').
Live-verified on an isolated flagged space: push (vault file edit -> Docmost
content, stamped lastUpdatedSource='git-sync') and pull (Docmost rename -> vault
file + meta) both work; an unrelated 92-page space stayed untouched throughout.
