F4: a rename/move + body edit in one diff used to lose the edit (renamed pages
went only into renamesMoves, never updates). Now computePushActions also
emits an updates entry for renames, AND threads the OLD path via a new
UpdateAction.basePath so applyPushActions resolves the 3-way merge base from
the pre-rename file. Without it the base lookup at the new path returns null
and degrades to a 2-way merge that rolls back concurrent Docmost edits; with
it the edited block wins while a concurrent edit to another block survives.
A plain (status M) update carries no basePath and is byte-identical to before.
F5: test the CREATE path stripping conflict markers (autoMergeConflicts on).
F6: .env.example documents GIT_SYNC_REMOTE_TEMPLATE as deferred/inert scaffolding.

Bug #1 (push 503 starvation): an external receive-pack that briefly overlapped
a poll cycle immediately 503'd because the per-space single-writer lock was
held. Add a BOUNDED retry-acquire on the PUSH path only (SpaceLockService
.withSpaceLock acquireRetry: capped exponential backoff up to ~5s); a transient
overlap now waits and succeeds, a genuinely stuck cycle still 503s after the
bound. The poll cycle passes no retry (immediate skip). Push result stays
deterministic: the receive-pack only runs once the lock is held, so a 503 never
leaves a half-applied ref.
Bug #2 (concurrent-edit marker leak + silent same-block loss):
- Marker leak (a): the push UPDATE path stripped markers for the body sent to
Docmost but left raw <<<<<<</>>>>>>> committed on the published `main` vault
forever (autoMergeConflicts ON). Now the cleaned body is written back to the
vault file + recorded in writtenBack so runPush commits it on `main` and the
vault converges to clean bytes.
- Marker leak (b): pin merge.conflictStyle=merge in ensureRepo and teach
stripConflictMarkers/hasConflictMarkers about the diff3 `|||||||` base section
(drop the marker AND the stale base region) so diff3/zdiff3 conflicts can
never leak `|||||||` + base content into a page. Also scrub the 3-way merge
BASE markdown.
- Silent same-block loss: the block 3-way merge still resolves same-block
conflicts deterministically to git, but it is no longer silent: diff3Plan now
reports a conflict count (mergeXmlFragments3WayWithStats), gitSyncWriteBody
logs it, and the persistence boundary-snapshot now fires for git-sync writes
over a non-git-sync baseline so the human's pre-merge content is preserved in
page history (recoverable). Full both-preserved persisted-conflict UI remains
the deferred redesign.
Tests: space-lock bounded-retry (success/stuck/poll-immediate); push vault-clean
+ diff3 ||||||| strip; ensureRepo conflictStyle pin; diff3Plan/3-way conflict
counts; persistence git-sync boundary snapshot. Server tsc clean; git-sync
vitest + server collaboration/git-sync jest all green.

Red-team #13 (conflict markers reaching Docmost) is now a per-space policy
exposed as a UI toggle, instead of a hardcoded behavior. New boolean
`gitSync.autoMergeConflicts` (default FALSE), mirroring the existing per-space
`gitSync.enabled` flag end-to-end (jsonb space settings -> update-space DTO ->
space.service -> client types -> space settings form switch):
- OFF (default, safe): a page whose committed body still has unresolved git
conflict markers is NOT pushed — it is recorded as a per-page push FAILURE
("unresolved conflict markers — resolve in git first"). Recording a failure
(not a soft skip) deliberately HOLDS refs/docmost/last-pushed so the conflict
commit is never marked pushed and a later pull cannot clobber the user's
in-progress resolution; the page retries until the conflict is resolved in git.
- ON: the marker lines are stripped and both sides' content is pushed (the prior
behavior), so the conflict becomes visible/fixable inside Docmost.
The engine Settings carries `autoMergeConflicts`; runPush threads it into the
update AND create paths. The orchestrator's buildSettings reads the per-space
flag from jsonb (strict opt-in like `enabled`, default false).
Tests: redteam-push-cycle #13 rewritten (default -> not pushed + failure + refs
held; ON -> strip-and-push); space.service + edit-space-form + orchestrator
specs extended. git-sync vitest 618, server jest space+git-sync 163, client
edit-space-form 11, server/client tsc clean.

A 10-agent red-team pass on the two-way Docmost<->git sync surfaced 16 ranked
findings (9 others triaged out as already-defended). Wrote a reproduction test
per finding (each asserts the CORRECT behavior, so it fails on the bug), then
fixed the production code so every repro goes green. All confirmed bugs:
Round-trip data loss (markdown-converter.ts + docmost-schema.ts mirror):
- #1 editor-ext node types silently dropped on export — ported the 8 missing
canon nodes (footnoteReference/footnotesList/footnoteDefinition, htmlEmbed,
status, pageEmbed, transclusionSource/Reference) into the git-sync schema
mirror and added converter cases that emit their schema-matching HTML instead
of flattening unknown nodes to '' (this was the critical data-loss flagged in
review #1679: footnotes/htmlEmbed lost on sync). Snapshot surface updated.
- #2 top-level image lost width/height/align/attachmentId — now emits an HTML
<img> (like video/diagrams) when it carries layout attrs; bare images stay
. Image node parses width/height as strings so they re-import.
- #3 code block containing a ``` fence corrupted on round-trip — outer fence is
now widened to (longest-inner-backtick-run + 1).
- #16 deep nesting threw RangeError (page never synced) — added a depth guard
(MAX_NODE_DEPTH=400) so the converter never overflows the stack.
Push/layout/cycle (engine):
- #4 disambiguation ' ~slugId' suffix corrupted Docmost titles + order-dependent
layout — deterministic, order-independent sibling disambiguation; suffix is
stripped from a path-derived title ONLY when the new name is exactly the old
title plus the suffix (never a genuine retitle ending in ' ~token').
- #6 retry-adopt by (parent,title) clobbered the wrong duplicate-title sibling —
ambiguous (parent,title) is no longer adopted (falls back to fresh create).
- #12 a new child under a new parent was created at ROOT — creates are ordered
parent-before-child with an in-memory created-id map for parent resolution.
- #13 git conflict markers could reach Docmost — bodies are scanned and the
marker lines stripped (a '=======' line is only treated as a conflict
separator inside a <<<<<<< ... >>>>>>> block, so setext headings are safe).
- #15 a divergent `docmost` mirror was escalated by runPush but dropped by
runCycle — RunCycleResult now forwards divergentDocmost to the orchestrator.
Server (merge / lock / provenance):
- #9 3-way merge lost a human's block edit when git inserted an adjacent block —
finer-grained diff3 region merge (via lcs) preserves non-overlapping human
edits; genuine same-block conflicts still resolve git-wins.
- #10 single-writer race — module-static liveLocks closes the same-process TOCTOU
window, and a heartbeat refresh that cannot confirm the lock now aborts the
cycle at its next write checkpoint (cooperative AbortSignal threaded through
runCycle). Cross-process fencing tokens remain a follow-up.
- #14 sticky-agent provenance overrode an explicit actor='git-sync' write,
blinding the listener loop-guard — resolveSource now lets an explicit actor
win over the sticky-agent fallback (explicit agent still wins).
Verified: git-sync vitest 617 pass (+1 expected-fail), server unit jest 1541
pass, server tsc clean. A review pass over the fixes caught and corrected a
title-suffix over-strip, an inert abort signal, a document-wide conflict-marker
strip, and two leaf-atom content-holes.

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.

Closes the architecture item from the #119 review: drop the "vendored from
docmost-sync" framing and the CJS↔ESM `Function('import()')` bridge so the engine
is a normal first-class gitmost package.
Part 1 — vendoring markers removed (prose only, zero behavior change): reworded
"VENDORED into gitmost" / "vendored from docmost-sync" / "Engine LOGIC is
byte-identical" / "it's a port" comments across the engine. Behavior-bearing
strings are untouched: BOT_AUTHOR_NAME/EMAIL and the `Docmost-Sync-Source:`
provenance trailers (changing them would break git authorship + the loop-guard).
Part 2 — the package is now ESM (matching the sibling @docmost/mcp): `type: module`,
tsconfig Node16, `.js` extensions on relative imports, and a static
`import { marked }` replacing the `new Function('return import(...)')` /
`loadMarked` hack — the bridge is GONE from the package. The CommonJS NestJS
server loads the now-ESM engine via a new `git-sync.loader.ts` that mirrors the
existing `docmost-client.loader.ts` mcp loader exactly (Function-indirected
dynamic import + cached promise + retry-on-reject). The 4 server consumers
(orchestrator/datasource/vault-registry/git-http-backend) call `await loadGitSync()`
for value exports; types stay `import type` (erased). The converter-gate spec —
which needs the real converter — loads the package's TS source via a jest
moduleNameMapper + isolatedModules (documented in that spec); the other git-sync
specs mock the loader.
Verified: engine builds pure ESM (no Function/require leftover), vitest 614,
editor-ext build, server + client tsc, full server jest 1397/0. Live stand
smoke-test: server starts clean on the ESM engine (no ERR_REQUIRE_ESM), a real
sync cycle runs through the loader, and the basic e2e suite is 12/12 (clone via
git-http-backend, push, pull, delete, 3-way merge — all through the new loader).

Self-review of phase 3 caught a data-corruption regression: nativeMeta always
supplies the run's spaceId, so the planner's 'create-without-spaceId' skip — which
had doubled as the only filter for non-page files — went dead. An ADDED
.obsidian/*.json, attachment, or dotfile (committed to the vault, no .gitignore)
would then be classified as a CREATE: a junk Docmost page, plus a gitmost_id
frontmatter written INTO the file, corrupting it.
Fix: isPageFile(path) — a .md file with NO dot-segment anywhere — and filter the
diff to page files at the very top of computePushActions, BEFORE any
classification, so non-page A/M/D/R are ignored (design §Адопция). 2 unit tests
pin it (.obsidian/json, attachment, dotfile, dot-segment, .md dotfile all ignored;
real pages still created). 614 engine tests green.
Also: refreshed stale docmost:meta comments to gitmost_id (review SUGGESTION), and
documented the deferred adoption frontmatter-preservation gap (review WARNING) in
page-file.ts + the design doc (do NOT roll native onto a real vault with Obsidian
properties until phase 4 round-trips them).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

Follow-up to 4376c5a6, found by a real BROWSER e2e (the flow the in-diff fix
missed). When the layout reshuffle's two halves land in SEPARATE sync cycles, the
later cycle's diff has only the DELETE of the old path — the matching add was
already pushed — so in-diff D+A coalescing can't see it, and the live page was
still trashed.
Robust fix on the identity invariant the reviewer (and the user) called out: a
page EXISTS iff its pageId is in the vault, regardless of filename. runPush now
collects the pageIds present at ANY path in the current `main` tree and passes
them to computePushActions; a deleted file whose pageId is still tracked
elsewhere is a MOVE, never a deletion. (Built only when the diff has deletes.)
Adds apps/server/test/git-sync-browser-e2e.cjs — a Playwright test that drives the
REAL Docmost web UI: log in, create several untitled pages, type a title, sync,
assert NOTHING is trashed. Reproduced the data loss before this fix; 5/5 green and
stable after. Engine suite 600 green (+2 computePushActions cases:
pageId-still-present -> skip; pageId-gone -> real delete).

CRITICAL data-loss bug: creating pages in Docmost (which start UNTITLED) and then
typing a title could soft-delete OTHER pages. Untitled pages all serialize to the
`_` fallback filename; the layout disambiguates them (`_.md`, `_ ~slug.md`).
Retitling one frees the bare `_` and another untitled page's file relocates into
it. git's rename detection (`-M`) can't see the move (the tiny meta-only files are
too dissimilar), so `git diff` reports it as DELETE(old) + ADD/MODIFY(new). The
push took the DELETE literally and trashed a live page.
Root cause is that the push trusted git's path-level rename heuristic for page
IDENTITY. Identity is the pageId. Fix: before emitting any delete, coalesce by
pageId — a pageId that is BOTH deleted (pre-image) AND present on the surviving
side (current meta of an ADD or a MODIFY, since a relocation into an occupied path
shows as M) is one page that MOVED, classified as a rename/move and NEVER a delete.
Reproduced + verified on a live stand: 4 untitled pages + retitle one trashed a
different page before; after the fix, retitling one (and stress-retitling all)
trashes nothing. Engine suite 598 green; 3 new computePushActions cases (ghost
D+A move -> rename; real delete still deletes; unrelated D+A stay delete+update).

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.

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.
