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).

Resolve the code-review findings from comment #1571 on PR #119.
Engine (packages/git-sync):
- Idempotent CREATE on retry: before createPage, look the page up in the
live Docmost tree by (parentPageId, title) and ADOPT it instead of
duplicating when a prior cycle created it but failed to persist the
pageId back to disk. Only trust a COMPLETE tree for the lookup; fall
back to createPage otherwise. Covered by new tests incl. a complete=false
regression-lock.
- Route applyPullActions diagnostics through an injected logger instead of
bare console (thread log from the cycle).
- Add a timeout to the git execFile chokepoint (runRaw) so a hung git
subprocess cannot wedge a sync cycle.
- Translate remaining Russian code comments to English.
- Remove dead standalone-CLI code (parseArgs/PushParsedArgs,
parseSettings/envSchema, loadSettingsOrExit + config-errors.ts) and the
matching index exports/specs; keep the Settings type.
- Fix the dangling docs link in package.json.
- Add a schema-surface snapshot guard so any drift in the vendored
document schema is a loud, must-review CI failure (+ provenance header).
Server (apps/server):
- Add a configurable watchdog timeout to the spawned git http-backend so a
stalled push cannot hold the per-space lock forever
(GIT_SYNC_BACKEND_TIMEOUT_MS).
- Close the in-process TOCTOU window in SpaceLockService.withSpaceLock by
reserving the slot synchronously before acquire.
- Add tests: removePage git-sync provenance (both branches), ensureServable
force-push-protection git configs, and the phase-B+ datasource methods.
Docs / build:
- AGENTS.md: list git-sync as the fifth workspace package and note the
three schema mirrors; fix the dangling git-sync-plan.md backlog link.
- pnpm-lock.yaml: add the missing @docmost/git-sync workspace link so
pnpm install --frozen-lockfile (CI default) succeeds.

PUSH now consumes the native-Obsidian format end-to-end:
- identity from the gitmost_id frontmatter (parsePageFile), not docmost:meta;
- title from the FILENAME, parentPageId from the enclosing folder's folder-note
(parentFolderFile is now FOLDER-NOTE aware: a child's parent is dir/dir.md, and
a folder-note's own parent is one level up), spaceId from the run (every vault
file belongs to the vault's space);
- CREATE derives title/parent/space from path + run and writes the assigned
pageId back as gitmost_id frontmatter (serializePageFile);
- UPDATE pushes the STRIPPED body (current + 3-way-merge base), so the frontmatter
never leaks into Docmost content; the loop-guard hashes the body.
The PURE delete-sensitive classifier (computePushActions/classifyRenameMoves) is
UNCHANGED — only the injected IO resolvers (metaAt, parent, create write-back)
switched source. nativeMeta always carries the run spaceId, so the legacy
'create-without-spaceId' skip no longer fires through runPush.
Tests rewritten to native fixtures + folder-note parent paths; the noop case is
now a child under a renamed parent folder (filename=title, so a path-only-noop
needs an ancestor rename). parentFolderFile tests cover leaf/folder-note/nested/
dotted. 612 engine tests green; engine rebuilt.

Upgrades the 2-way body merge to a real diff3 three-way merge (review #5), so a
block ONLY the human changed is KEPT when git changed a DIFFERENT block — the
2-way merge would revert it to git's stale version.
Engine: the push update loop reads the last-synced pre-image
(`git.showFileAtRef(refs/docmost/last-pushed, path)`) and passes it as the
optional `baseMarkdown` to `client.importPageMarkdown` (the common ancestor).
Server: gitmost-datasource converts base+incoming, and writeBody runs a block-
level diff3 (new three-way-merge.ts `diff3Plan`): live-only change -> keep live,
git-only change -> take git, both-changed -> git wins (conflict policy), inserts/
deletes from either side preserved. Without a base (createPage) it falls back to
the 2-way merge. Crash-safety unchanged (docs built before the connection opens).
Tests: three-way-merge.spec.ts (14 — every diff3 case incl. the cross-block
preservation and conflict policy), yjs-body-merge 3-way (real Y.Docs: human's
block instance preserved while git's block is applied), plus an engine test that
the base is forwarded from showFileAtRef. Existing push assertions updated for the
new base arg. git-sync 589 pass; server merge/datasource/gate 62 pass; typecheck
clean.
