Что это

Продолжение и замена #119 (закрыт в пользу этого PR: там 69 комментариев и 14 раундов ревью — полная история по ссылке). Ветка feat/git-sync-2 = голова feat/git-sync (e46e89b5, approved round 14) + свежий merge develop, которым уже поглощён #350.

Статус вливания: ЗАМОРОЖЕНО (#326, шаг 6b). Этот PR — площадка тестирования синка до стабилизации; мерж — только по явной команде мейнтейнера.

Краткое содержание предыдущих серий

Фича: нативный двусторонний синк страниц спейса ↔ git-папка Markdown. Движок pull/push/reconcile/stabilize + оркестратор (Redis leader-lock, per-space мьютекс), PageChangeListener с loop-guard, git smart-HTTP хост (git clone/push http://…/git/<spaceId>.git, Basic-auth + CASL, 404-не-403), per-space opt-in тоггл, провенанс git-sync, admin-trigger.
Эпопея #119: ~65 дефектов найдено и закрыто ДО вливания (12+ критичных data-loss/wedge: F4 rename+edit, echo-revert, cross-space move→Trash, S2 confused-deputy, id-wedge ×4, index.lock…), эскалация к человеку, анти-луп протокол («стенд ≠ jest», вывод тестов прикладывается).
Конвертер вынесен и консолидирован (#293 → #333): единый пакет @docmost/prosemirror-markdown + канонические форматы (решения №1–№9: inline-сноски ^[…], , Obsidian-callouts, $…$ , ==…==, комментарии-дискриминаторы медиа, ); #350 — класс «""≡absent». С шага 6a (#326) ветка живёт на пакете, собственной копии конвертера у синка больше нет — диф PR похудел с 305 до ~119 файлов.

Оговорки для тестирующих (важно)

Vault пишется в новом каноне. Легаси-vault'ы стендов при первом цикле будут переписаны stabilize-проходом — разовый большой дифф ожидаем, это миграция, не баг. Лучше стартовать с чистого vault либо пометить первый прогон как миграционный.
Маршрутизация багов: конвертер → fixtures-first PR в пакет на develop (в ветке чинить негде и НЕЛЬЗЯ — guardrail №2 #326), ветка забирает merge'ем; движок/оркестратор/http/UI → сюда.
Рассинхрон конвертеров как класс закрыт по построению: один пакет + attribute/serializer contract-тесты против editor-ext — дрейф схемы теперь красный CI, а не тихая потеря данных. Отдельно живёт md-слой editor-ext (экспорт/импорт/вставка) — синк его не использует, консолидация — #345/#347.
#350 уже здесь: merge чистый, alt-фикс в пакете; в гейте флипать было нечего (align-ассерт корректен — это канон-нормализация; alt-ассерта не было). На старых страницах с картинками без описания возможен разовый alt: ""→null дифф — ожидаем.
Регламент merge develop — guardrail №6 (#326): регенерация лока при конфликте + pnpm install --frozen-lockfile в чистом чекауте ДО push, вывод прикладывается (класс «merge ломает lock» стрелял дважды).

Известные хвосты движка (осознанно открыты, из финала #119)

D3-N2 (corrupt loose object → re-init), D2-D1 (fencing tokens / SIGKILL-лок до TTL), valid-but-nonexistent PARENT uuid wedge (4-й вариант id-класса), orphan .md при опустошении спейса (SPEC §8 — осознанный guard, решение мейнтейнера), инкрементальный pull (перф, «с бенчем, не вслепую»).

Верификация этой головы

merge develop → чистый (конфликтов 0, lock не тронут);
pnpm install --frozen-lockfile → Done (guardrail №6);
@docmost/git-sync vitest → 268/268;
гейт git-sync-converter-gate.spec.ts → 29/29 (на дереве с поглощённым #350).

Голова сдвинулась относительно approved e46e89b5 (merge-коммит) — нужен review-round на текущую голову.

feat(git-sync): vendor pure converter + engine into @docmost/git-sync (Phase A.1) 56ab17fbc2

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.

feat(git-sync): CommonJS build + §13.1 editor-ext idempotency gate (Phase A.2) b0cd4bd6cf

Make @docmost/git-sync natively consumable by the CommonJS server (and jest):
build to CommonJS (tsconfig module CommonJS, drop type:module, strip .js from
relative imports), and lazy-load the only ESM-only dep (marked) via the dynamic
Function('import()') trick (mirrors docmost-client.loader.ts) with a require()
fallback so vitest's evaluator works too. git-sync tests stay green (314 pass,
3 expected fail).

Add the §13.1 idempotency gate (apps/server .../git-sync-converter-gate.spec.ts):
13 editor-ext docs (paragraphs/headings, marks, links, bullet/ordered/task lists,
blockquote, callouts, code block, hr, table, nested mix) round-trip
content(editor-ext) -> convertProseMirrorToMarkdown -> markdownToProseMirror ->
TiptapTransformer.toYdoc/fromYdoc(tiptapExtensions) -> canonicalize and assert
docsCanonicallyEqual. All green => the vendored converter's docmost-schema is
schema-compatible with editor-ext (no node/mark/attr loss), which the plan §13.1
requires before Phase B. The one intrinsic markdown-image lossiness (width/height
/align can't ride plain ![](src)) is isolated in a KNOWN DIVERGENCE block, not
hidden. Server tsc clean.

feat(git-sync): vendor IO engine (pull/push/git/settings) with GitSyncClient seam (Phase A.3) 70bd0dba4d

Vendor the IO engine from docmost-sync into packages/git-sync/src/engine:
- git.ts (VaultGit, execFile shell-out — verbatim)
- pull.ts (readExisting, computePullActions, applyPullActions)
- push.ts (classifyRenameMoves, computePushActions, applyPushActions, runPush)
- settings.ts adapted (pure parseSettings + Settings type; no process.env binding
  — the server builds Settings from EnvironmentService later), config-errors.ts.
CLI main()/import.meta entrypoints dropped (server drives in-process).

Client seam: new engine/client.types.ts defines GitSyncClient; pull.ts/push.ts
now use Pick<GitSyncClient, ...> instead of the non-vendored DocmostClient. Engine
logic byte-identical except a zod4-compat fix in config-errors (zod4 dropped the
issue.received==='undefined' signal; match /received undefined/ on the message).

Ported the engine unit tests (compute/apply pull+push actions, classify-rename-
moves, run-push, settings, config-errors) incl. real-git temp-repo tests: 431
pass / 3 expected-fail (was 314/3). REST/CLI-coupled upstream tests skipped
(noted). CJS build clean. No apps/server wiring yet (next step).

feat(git-sync): native GitmostDataSource + 'git-sync' provenance (Phase A.4a) 5a4d9f84d7

Native data plane for git-sync (plan §3, §8.1):
- provenance: widen actor to 'user'|'agent'|'git-sync' (jwt-payload,
  auth-provenance decorator); PersistenceExtension resolves lastUpdatedSource
  with precedence agent > git-sync > user, debounced history (like a human edit,
  not the agent's immediate snapshot).
- GitmostDataSourceService implements @docmost/git-sync's GitSyncClient natively:
  reads via PageRepo/SpaceRepo (listSpaceTree complete:true, getPageJson), writes
  via PageService (create/removePage soft-delete/movePage with computed fractional
  position/update-rename/restore) + the writeBody linchpin through collab
  openDirectConnection('page.'+id, {actor:'git-sync'}) mirroring
  collaboration.handler withYdocConnection 'replace'. bind({workspaceId,userId})
  returns the context-bound client for the orchestrator.
- 10 unit/contract tests (mapping + soft-delete + move-position), tsc clean.

Known gap (closed in A.4b): PageService.create/update/movePage only branch on
actor==='agent'; git-sync provenance is already passed through so the row source
marker propagates once PageService honors 'git-sync'. Module/orchestrator/config
come next.

feat(git-sync): GitSyncModule orchestrator + config + listener (Phase A.4b/B) e2493cafa9

Control plane wiring (plan §5-§11):
- PageService create/update/movePage now honor provenance actor 'git-sync'
  (stamp lastUpdatedSource='git-sync'), closing the A.4a gap.
- EnvironmentService: GIT_SYNC_ENABLED / DATA_DIR / REMOTE_TEMPLATE /
  POLL_INTERVAL_MS / DEBOUNCE_MS / SERVICE_USER_ID (required-if-enabled) /
  SSH_KEY_PATH + validation.
- VaultRegistryService: per-space vault path + cached VaultGit.
- GitSyncOrchestrator: per-space Redis leader-lock (SET NX PX + CAS-Lua release,
  randomUUID instanceId) + in-process mutex; runOnce drives the vendored engine
  PULL (readExisting->computePullActions->applyPullActions) then PUSH (runPush)
  with the bound native GitSyncClient + VaultGit; @Interval poll-safety gated on
  GIT_SYNC_ENABLED; imports plain ScheduleModule (TelemetryModule owns forRoot).
- PageChangeListener: @OnEvent PAGE_* -> per-space debounce -> runOnce, with a
  best-effort lastUpdatedSource==='git-sync' loop-guard.
- GitSyncController: admin POST /api/git-sync/trigger + GET /status (ops/e2e).
- GitSyncModule registered in app.module. Enabled-space enumeration uses
  settings.gitSync.enabled, falling back to all live spaces until Phase C writes
  the flag (master gate = GIT_SYNC_ENABLED).

tsc clean; 713 tests/71 suites pass; dev server hot-reloaded the module (route
live, DI graph boots). Live pull/push round-trip verified next.

fix(git-sync): branch choreography + strict scoping + delete cap (Phase B hardening) 8373360a67

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.

feat(git-sync): per-space 'Enable Git sync' toggle (Phase C, §7.1) e0e01157c2

UI opt-in for git-sync, mirroring the existing sharing/comments settings pattern
(no new endpoint, no new mechanism; orchestrator read query untouched):
- UpdateSpaceDto.gitSyncEnabled?: boolean.
- SpaceRepo.updateGitSyncSettings: jsonb-merge into settings.gitSync.<key>
  (COALESCE || jsonb_build_object — never clobbers sibling sharing/comments);
  stored as a real jsonb boolean so the orchestrator's
  settings->'gitSync'->>'enabled' = 'true' matches.
- SpaceService.updateSpace handles the flag (audit diff) via the existing
  CASL-guarded space update path (Manage/Settings).
- client: Switch in edit-space-form (optimistic mutate + revert-on-error,
  readOnly-aware) + space types + 2 i18n keys.
- space.service.spec extended (calls updateGitSyncSettings; no-op when undefined).
tsc clean (server+client); jest src/core/space 4 pass.

feat(git-sync): client 'Git sync' provenance badge + git in runtime image (Phase D) 582e1976cc

- page-history history-item: a lastUpdatedSource==='git-sync' version renders a
  neutral gray 'Git sync' badge (git-merge icon), NOT the agent badge/deep-link
  (it is not an agent edit). +2 i18n keys.
- Dockerfile: install git in the installer (runtime) stage — VaultGit shells out
  to git, so assertGitAvailable() needs the binary at runtime.
Client tsc clean.

fix(git-sync): address review — configurable poll, always-on loop-guard, cleanup 593f181bbc

Comprehensive-review follow-ups (APPROVE WITH SUGGESTIONS; no critical issues):
- poll interval is now actually configurable: replaced the hardcoded
  @Interval('git-sync-poll', 15000) with a dynamic SchedulerRegistry interval
  registered in onModuleInit from getGitSyncPollIntervalMs() (cleared in
  onModuleDestroy); /status and the real cadence now share one config source.
  Boots logging 'poll interval registered (Nms)'.
- loop-guard now ALWAYS applies: the lastUpdatedSource==='git-sync' skip was
  nested inside the !spaceId/!workspaceId branch, so structural self-writes
  (CREATE/MOVE/RESTORE/SOFT_DELETE, which carry spaceId+workspaceId) bypassed it
  and re-triggered cycles. Fetch the page row once, guard unconditionally, then
  resolve space/workspace.
- remove the dead PAGE_CONTENT_UPDATED subscription (it's a BullMQ job, never an
  EventEmitter event; body edits arrive via PAGE_UPDATED).
- fix the stale datasource comment (PageService DOES stamp 'git-sync' now).
- env getters: parseInt radix 10 + NaN/<=0 fallback for poll/debounce (+ max
  deletes), with 6 new environment.service.spec tests.

tsc clean; jest 723 pass; live cycle re-verified post-refactor (ran, push
applied, unflagged 92-page space untouched).

test(git-sync): add reviewer-requested coverage across engine, server, client d9d1d54aaa

Implements the test cases called out in the PR #119 review threads
(code-review, test-strategy report, red-team) — TESTS ONLY, no production
code changes.

packages/git-sync (vitest):
- lib converter/markdown gaps: pageBreak data-loss (it.fails repro),
  subpages lossy round-trip, nested/fenced callouts, ol->taskList bridge,
  column.width number<->string drift, empty details.
- engine units: parentFolderFile, planReconciliation swap/chained move,
  buildVaultLayout last-resort-by-id, firstDivergence, applyPushActions /
  applyPullActions failure isolation.
- real temp-git integration: diffNameStatus -z rename+add/modify
  alignment, copy-line behavior, per-invocation committer identity (no
  leak into repo/global config).
- ENFORCED type-level GitSyncClient contract via vitest typecheck over a
  *.test-d.ts file (tsconfig.vitest.json; build tsconfig untouched).

apps/server (jest):
- orchestrator: delete-cap neutralization + fail-safe, Redis lock / mutex
  skip ladder + release-on-throw, merge guard, pull/push order, remote
  template substitution, poll lifecycle.
- page-change listener: loop-guard, debounce coalescing, id resolution,
  error swallowing.
- vault registry, controller authz (trigger + status), env
  validation/getters, page.service git-sync provenance stamping,
  persistence precedence (agent > git-sync > user) + no boundary snapshot,
  space.service audit-delta, space.repo jsonb-merge, converter-gate corpus
  extension (mention/math/details/marks).

apps/client (vitest + testing-library):
- history-item git-sync badge: render gating + non-clickable.
- edit-space-form toggle: initial state, optimistic payload, rollback on
  error, disabled states.

feat(git-sync): serve spaces over smart-HTTP (gitmost as a two-way git host) 04032ae677

Expose each git-sync-enabled space as a clonable/pushable git repo over HTTP,
so `git clone https://<user>:<pass>@<host>/git/<spaceId>.git` works and external
pushes flow back into Docmost pages — gitmost itself acts as the git host (no
external GitHub/Gitea, no SSH).

Transport: shell out to `git http-backend` (CGI; git is already in the runtime
image) which implements the full smart-HTTP protocol (info/refs, upload-pack,
receive-pack, protocol v2). A raw Fastify route `/git/*` (mounted at the root,
outside the `/api` prefix) bridges the request/response to the CGI; passthrough
content-type parsers for the git media types stream the raw body to stdin.

Reuse the existing engine: clients push the vault's `main` branch, whose commits
beyond `refs/docmost/last-pushed` the engine already reconciles into Docmost.

- http/git-http.service.ts — auth (HTTP Basic -> AuthService.verifyUserCredentials),
  self-resolved workspace (DomainMiddleware does not run for this raw route),
  per-space gating (global + per-space gitSync flags, 404 hides existence),
  CASL authz (Read=fetch, Manage=push), dispatch.
- http/git-http-backend.service.ts — spawn `git http-backend`, binary-safe CGI
  response parsing (Status/headers/body), stream to the socket.
- http/git-http.helpers.ts — pure path parse, service->kind mapping, gate decision
  (unit-tested); rejects literal and percent-encoded path traversal.
- orchestrator: extract reusable withSpaceLock (CAS-guarded lock heartbeat so a
  long push cannot let the lock expire mid-cycle) and add ingestExternalPush
  (receive-pack + Docmost cycle under one lock; 503 on contention).
- vault-registry: ensureServable() — ensureRepo + idempotent receive.denyCurrentBranch
  =updateInstead / denyNonFastForwards / http.receivepack / http.uploadpack.
- env: GIT_SYNC_HTTP_ENABLED (defaults to GIT_SYNC_ENABLED) + validation.
- main.ts: register the /git/* route and the git content-type parsers.

Tests: pure helpers, CGI parsing, and the GitHttpService handler (auth/gate/authz
+ workspace resolution). Server tsc + git-sync/env suites green.

test(git-sync): exhaustive converter coverage + fix 3 round-trip data-loss bugs d06cf97ed6

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).

fix(docker): ship packages/git-sync into the runtime image 02daccc453

The server requires @docmost/git-sync (main: ./build/index.js) at runtime, but
the installer stage copied only editor-ext and mcp — so the image built fine and
then crashed on startup with `Cannot find module '@docmost/git-sync'`. Copy the
package's freshly-built build/ + package.json, mirroring the mcp/editor-ext COPY
lines. (Addresses review finding #1 on PR #119.)

fix(git-sync): don't clobber pages with a live editing session; crash-safe body write 181a8330f3

Review finding #5: the git -> page body write (writeBody) did a full-body replace
(delete-all + re-insert) on the shared Yjs doc. Applied while a human is editing
the page, it discarded their in-flight changes; and TiptapTransformer.toYdoc ran
AFTER the fragment was cleared, so a conversion failure could leave the page with
an empty body.

Fixes:
- Active-session guard: CollaborationGateway.getActiveEditorCount(documentName)
  reports live human (websocket) editor sessions for a doc, excluding server-side
  direct connections. writeBody now throws ActiveEditSessionError when an editor
  is connected. The engine's push loop already isolates each importPageMarkdown in
  try/catch and does not advance the loop-guard on failure, so the write is simply
  retried on the next poll once the editor disconnects — never a clobber.
- Crash-safe conversion: build the replacement Yjs update BEFORE opening the
  connection / clearing the fragment, so a transform failure can never leave the
  body empty.

Also updates the server-side converter gate spec to the corrected round-trip
shape: the block-image hoist no longer leaves a leading empty paragraph (the
git-sync converter fix in 7d39c16b, now reaching the built package).

A true merge of git content into a live Yjs session is out of scope (it needs a
real 3-way text merge with no shared update lineage); deferring the write while a
page is being edited is the safe, owner-approved minimum.

chore(git-sync): stop committing build/ and node_modules; build in CI/Docker 98253cf614

Review finding #2: packages/git-sync/build/ (the COMPILED engine) and the
package's node_modules/ were committed. Prod executed the committed build/ while
CI/tests ran src/ and never rebuilt it — so a fix in src/ could pass tests while
stale compiled code shipped (a silent src/prod skew). The committed node_modules
were pnpm symlinks with a baked machine-local store path (/home/claude/...),
useless and misleading for everyone else.

- git rm --cached packages/git-sync/{build,node_modules} (42 + 31 files).
- .gitignore: ignore packages/*/node_modules/ and packages/git-sync/build/.
- Build the package where it is actually consumed: apps/server `pretest` now
  builds @docmost/git-sync (its suite imports the built build/index.js), and the
  CI Test workflow gains an explicit "Build git-sync" step. The Dockerfile builder
  already runs `pnpm build` (nx builds the package) and now COPYs the fresh build/.

Verified: wiped build/, rebuilt via `pnpm --filter @docmost/git-sync build`, then
the server converter gate (26/26, imports the rebuilt package) and the git-sync
suite (588 passed) both pass against the freshly-built, non-committed output.

NOTE: packages/mcp/ has the same committed-build/node_modules pattern (pre-existing,
out of this PR's scope) and should get the same treatment in a follow-up.

fix(git-sync): merge git body into the live doc block-by-block (no clobber) 3386bf2865

Supersedes the active-session "defer" guard with a real merge (review #5 —
"запись делать через мерж", not skip-while-editing).

writeBody no longer does delete-all + re-insert (which discarded a concurrent
editor's in-flight changes on every sync). It now diffs the live body against the
incoming git body at TOP-LEVEL BLOCK granularity (LCS over a canonical structural
serialization) and applies only the minimal inserts/deletes:
- a block a human is editing is left UNTOUCHED when git changed a DIFFERENT block;
- an unchanged resync is a complete 0-op write;
- Yjs CRDT-merges the minimal ops with concurrent edits.

New yjs-body-merge.ts (mergeXmlFragments + cloneXmlNode + diffBlocks) is pure-Yjs
and unit-tested with real Y.Docs (8 tests): identical->0 ops, edit-one-block keeps
the other block instances, append/delete keep neighbours, marks survive the
cross-doc clone. Crash-safety kept: the incoming doc is built before the
connection opens, so a transform failure can't empty the body.

Removed: the ActiveEditSessionError defer path and the now-unused
CollaborationGateway.getActiveEditorCount.

Honest limitation: this is a 2-way merge — for a block BOTH sides changed since the
last sync, git wins (no common ancestor to decide). A full 3-way merge would need
the last-synced base plumbed from the engine; the dominant cases (unchanged
resync, edits to different blocks) are now lossless.

feat(git-sync): three-way body merge using the last-synced base (no edit loss) fa89cba023

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.

chore(mcp): stop committing build/ and node_modules; build in CI/Docker 807ff1f5f5

Same hygiene fix as git-sync (review #2), applied to packages/mcp which had the
identical pre-existing problem: committed build/ (20 files) + node_modules (28,
pnpm symlinks with a baked /home/claude store path).

- git rm --cached packages/mcp/{build,node_modules}.
- .gitignore: add packages/mcp/build/ (packages/*/node_modules/ already covers it).
- Build where consumed: apps/server `pretest` and the CI Test workflow now build
  @docmost/mcp too. The Dockerfile builder already runs `pnpm build` (nx builds
  mcp) and already COPYs packages/mcp/build into the runtime image.

Verified: wiped build/, rebuilt via `pnpm --filter @docmost/mcp build`; the mcp
server suites (96 tests) pass against the freshly-built, non-committed output.

docs(git-sync): document GIT_SYNC_* env vars; fix stale/non-English comments (PR #119 review) 8fa32e8438

Addresses the documentation/convention warnings from the #119 review:
- .env.example: add the GIT-SYNC block (9 GIT_SYNC_* vars with defaults), noting
  GIT_SYNC_SERVICE_USER_ID is required when sync is enabled.
- yjs-body-merge.ts: translate the Russian review note in the docstring to
  English (comments-only-in-English rule).
- persistence.extension.ts: correct the stale "git-sync writes are full-body
  replaces" rationale — a git-sync write is now a block-level merge into the live
  doc, which is why it is debounced like a human edit rather than snapshotted.
- history-item.tsx: the GitSyncBadge version is created on the PUSH path (writing
  the git body back into the doc), not by the pull — fix the comment.
- edit-space-form.tsx: log the raw error in the git-sync toggle catch instead of
  swallowing it (AGENTS.md).

fix(git-sync): hold refs on suppressed deletes + stamp delete/restore provenance (PR #119 review) 177d8a31d4

Two stability warnings from the #119 review:

1. delete-cap no longer drops deletions forever. When planned deletes exceed
   GIT_SYNC_MAX_DELETES_PER_CYCLE the apply client's deletePage now THROWS
   instead of resolving to a no-op. A throw is recorded by the engine as a
   per-page failure, so `refs/docmost/last-pushed` is NOT advanced past the
   commit that dropped the files — the next cycle re-diffs from the un-advanced
   ref and re-plans the same deletes (a transient over-cap is retried, not
   silently dropped and then recreated by the next pull). Previously a resolving
   no-op let the engine count `deleted++` with no failure, advance the ref, and
   never replay the deletions.

2. git-sync soft-delete and restore now stamp provenance. deletePage routes
   GIT_SYNC_PROVENANCE through pageService.removePage, and restorePage stamps
   lastUpdatedSource='git-sync' on the restore update — so the page-change
   listener's loop-guard (skip when lastUpdatedSource==='git-sync') recognizes
   both as its own writes instead of scheduling a wasted echo cycle. Done via a
   backward-compatible optional `lastUpdatedSource` param on
   pageRepo.removePage/restorePage (omitted for ordinary user deletes/restores).

The debounce map value carried `workspaceId`, but the scheduled cycle closes over

Replace the entry struct with `Map<string, NodeJS.Timeout>` (the timer handle is
all the map tracks). No behavior change. (page-change.listener.spec is in the

refactor(git-sync): extract SpaceLockService from the orchestrator (PR #119 review, arch #2 ) 95bc9fe98d

The per-space single-writer lock — Redis CAS leader lock (SET NX PX, DEL-CAS and
PEXPIRE-CAS Lua), the in-process mutex, the per-process instanceId and the
heartbeat — lived inline in GitSyncOrchestrator. Extract it into a dedicated
@Injectable() SpaceLockService exposing one narrow surface, withSpaceLock(spaceId,
fn), so the lock is the orchestrator's only Redis-lock touch-point and is testable
in isolation. The orchestrator now injects SpaceLockService and both consumers
(runOnce, ingestExternalPush) go through spaceLock.withSpaceLock — behavior
unchanged (same sentinel returns, same 503-on-lock-held contract). Orchestrator
drops 591→472 lines.

Adds space-lock.service.spec.ts asserting the lock SEMANTICS against a fake Redis
(the test-coverage warning from the review): the SET NX/PX args, the DEL-CAS and
PEXPIRE-CAS Lua + ARGV[1]=instanceId, plus the lock-held / in-progress / throw-
still-releases paths. The orchestrator spec is unchanged in count and stays green
(it now builds the real SpaceLockService over its mock Redis).

test(git-sync): cover ingestExternalPush in the orchestrator spec (PR #119 review) 085a30575f

Closes the test-coverage warning that the smart-HTTP push ingest path was
unexercised. Adds 5 cases: receive-pack streams BEFORE the Docmost cycle; a
held lock throws GitSyncLockHeldError and runs neither the receive-pack nor the
cycle; a post-push cycle error is swallowed (the push is durable, poll retries)
while the lock is still released; a missing service user runs the receive-pack
but skips the immediate cycle; and a globally-disabled git-sync refuses without
touching the lock.

(The 503/Retry-After mapping in git-http.service is the sibling warning; its spec
is in the repo's pre-existing set of jest suites that can't load locally via the
react-dom/tiptap transform chain, so that case is left for CI.)

fix(git-sync): drop the .git suffix from git http-backend PATH_INFO (smart-HTTP 404) 969c00aaf1

The /git smart-HTTP host 404'd EVERY fetch and push: PATH_INFO was built as
`/<spaceId>.git/<subpath>`, so `git http-backend` resolved the repo at
`<GIT_PROJECT_ROOT>/<spaceId>.git` — which does not exist. The vault is a NON-bare
working repo (the engine needs a working tree) at `<dataDir>/<spaceId>`, so the
CGI repo path must be `<spaceId>` (git http-backend serves the `.git` inside).
The URL's conventional `.git` suffix is already stripped to `spaceId` by
parseGitPath; re-appending it for PATH_INFO was the bug.

Found by standing up a full e2e stand (real Postgres/Redis + server + a real git
clone/push over the /git remote): clone and push both 404'd until this fix, after
which a clone → edit → push round-trips the change all the way into the Docmost
page.

Also extracts the CGI-env construction into a pure, exported `buildGitBackendCgiEnv`
and adds unit tests (the env build was previously untested — the gap this bug hid
in): a regression guard pinning PATH_INFO to `/<spaceId>/<subpath>` (no `.git`),
plus method/query/content-type/remote-user forwarding and the conditional
GIT_PROTOCOL.

refactor(git-sync): move the PULL->PUSH cycle into the engine as runCycle (PR #119 review, arch #1 ) dc7a0ec9f5

The reconcile choreography (ensureRepo -> merge-check -> ensureBranch ->
checkout('docmost') -> pull -> push) was hand-rolled in the app orchestrator's
driveCycle, duplicating an order the vendored engine owns and could drift from on
upgrade — the failure mode is data clobber. Lift it into @docmost/git-sync as a
single entry point, `runCycle(deps)`. The orchestrator now calls runCycle and
keeps only the lock (its caller) and the gitmost-specific delete-cap POLICY,
injected as the `resolveApplyClient` hook (the engine does the dry-run, hands the
hook the planned delete count — Infinity if planning failed — and uses whatever
client it returns for the apply). driveCycle drops from ~150 lines to ~30.

Tests:
- engine test/cycle.test.ts: composition (merge-in-progress short-circuit;
  ensureRepo->ensureBranch->checkout staging order before the pull; the cap hook
  is consulted with the planned count; no dry-run when no hook).
- engine test/cycle-roundtrip.test.ts: runCycle against a REAL VaultGit in a temp
  repo with a faked Docmost client — a git-originated CREATE flows pull->push and
  the assigned pageId is written back; an unresolved merge short-circuits before
  any client call.
- orchestrator spec rewired to mock runCycle and assert the wiring + the
  resolveApplyClient cap policy (the engine-internal cycle-order/merge tests moved
  to the engine).

Validated end to end on a live stand (real Postgres/Redis + server): a git clone
-> edit -> push over the /git remote round-trips the change into the Docmost page
through the refactored cycle.

test(git-sync): add a live two-way smart-HTTP e2e suite e528988d71

A runnable end-to-end suite that drives a LIVE git-sync stand over the real /git
remote — the integration counterpart to the unit tests. 10 checks across the full
feature:
- the auth/authz gate: no creds -> 401, wrong password -> 401, unknown space ->
  404 (existence never revealed), valid creds on a sync space -> 200;
- fetch: git clone over HTTP returns the vault markdown;
- push: a git-side edit propagates into the Docmost page;
- Docmost -> git: a page created via the API materializes as a vault file;
- delete: `git rm` + push soft-deletes the Docmost page (Trash);
- 3-way merge: a new git edit is added without clobbering prior page content.

Parameterized via env (SERVER/SPACE_ID/EMAIL/PASSWORD/DB_CONTAINER) and isolates
its own test page. It boots nothing — see the header for the stand prerequisites
(GIT_SYNC_ENABLED + a per-space gitSync flag + a service user). This is the suite
that caught the smart-HTTP PATH_INFO 404 bug.

test(git-sync): add advanced e2e suite — authz, protocol hardening, concurrency, data-loss guard 9baaf1ea58

Output of a generate→critique subagent pass on "what the feature's tests do NOT
cover", implemented + verified against the live stand (20/20). Complements the
basic two-way suite. Covers:

- protocol shape: unknown service subpath -> 400; unknown content-type -> 415
  (global allowlist); PUT/DELETE on pack endpoints -> 400;
- path-traversal: `..%2f..`, `%2e%2e%2f`, bare `.git` space-id -> 400/404, no
  escape, never a file leak;
- authz boundaries: a gitSync-DISABLED space -> 404 (existence hidden) and flips
  to 200 when enabled; a READER member can fetch (200) but is FORBIDDEN to push
  (403); a NON-member of an enabled space gets 403 (NOT 404 — the critic caught a
  wrong generator assumption here; pinned as a contract);
- concurrency: a push while the per-space Redis lock is held -> 503 + Retry-After,
  and the receive-pack does NOT mutate the vault;
- idempotency: repeated no-op cycles never churn `main` / `refs/docmost/last-pushed`;
- data-loss guard (PR #119): deleting MORE than GIT_SYNC_MAX_DELETES_PER_CYCLE is
  HELD — none trashed AND last-pushed does not advance past the delete commit
  (retry-safe, not silently dropped).

Auto-creates/tears down its fixtures (reader/non-member users, a 2nd space) and
resets the vault cache on exit so re-runs and the basic suite stay green. Needs
the vault dir + Redis container reachable (see header). A structural rename/move
case was intentionally left to the engine unit suite (git rename-similarity on
meta-only fixture pages is a fixture artifact, not a feature bug).

test(git-sync): basic e2e operates on a dedicated page + cleans up (no real-page pollution) ea1f8da906

The push / 3-way-merge cases edited the FIRST real `.md` in the vault, leaving
`E2E-PUSH-*` / `E2E-MERGE-*` marker headings accumulating in a real page, and the
Docmost->git case left its created page in the Trash. Now the suite creates a
dedicated `E2E-SyncTarget-*` page and targets only that, and a teardown
hard-deletes every `E2E-*` fixture page and converges the vault on exit — so runs
never mutate real content and leave the stand clean.

fix(git-sync): never trash a page that only MOVED (pageId-identity, not git rename heuristics) — data loss c3dbee9fbf

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).

fix(git-sync): never trash a page whose pageId still exists in the tree (cross-cycle move) + browser e2e 40ca04eb08

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).

space (+ its vault) on exit. Set SPACE_ID explicitly to opt into an existing

pages left behind, the real space untouched.

docs(git-sync): design for thin meta + third-party-editor support 53febfd5b9

All service metadata moves into a single `.gitmost/index.json` sidecar; the `.md`
files become clean markdown (Obsidian & any editor work directly). The page tree
mirrors the folder structure (folder = parent page; the parent's body lives in
`<Folder>/index.md`); collisions disambiguate by a `~<slugId>` filename suffix
with identity tracked by pageId in the index (safe renames, never delete+create —
backed by 5133bb34). Bare files/folders from a third-party editor are adopted into
pages. Includes the migration path off the current `docmost:meta`-in-file format
and a phased plan (each phase gated by engine unit tests + the browser e2e +
isolated shell e2e). Agreed with the owner 2026-06-24.

Pure read/write/lookup for the vault sidecar index that will hold page identity

clean markdown. parseVaultIndex is tolerant (missing/garbage/bad entries degrade

docs(git-sync): thin-meta design — identity must travel with the file (B/C) + link-sync phase 5d4eb8ede2

Captures the design discussion: a path-keyed sidecar is NOT a safe source of
truth (a git-undetected rename loses the page), so the id must travel WITH the
file — either as a slugId suffix in the filename (B) or a minimal YAML frontmatter
`id:` (C); both robust, B/C is the open UX decision (author leans C for clean
names). The sidecar may remain an optional path->id cache. Adds phase 6 — link
sync between notes: Docmost links are by pageId (survive rename), vault markdown
links are by path (rewrite on rename, Obsidian-style); independent of B/C and the
format phases.

feat(git-sync): native-Obsidian format — phase 1 = page-file (frontmatter gitmost_id) a91405632e

Pivot the thin-meta design to "the vault IS a native Obsidian vault": clean
markdown + a minimal YAML frontmatter `gitmost_id:` (the durable pageId, travels
with the file so identity survives any move); folders mirror the page tree with
the parent's body as a folder-note `<Folder>/<Folder>.md` (LostPaul Folder Notes
convention); links as `[[wikilinks]]` (basename-resolved → reparent never breaks a
link, only retitle does); collisions disambiguated Obsidian-style; `.obsidian/`
and non-page files left untouched (no .gitignore). Verified the conventions
against the Obsidian/Folder-Notes docs.

Replaces the abandoned `.gitmost/index.json` sidecar (path-keyed → fragile to
git-undetected renames; the in-file id is self-sufficient): removes vault-index.ts.
Adds lib/page-file.ts — parsePageFile/serializePageFile (frontmatter id + clean
body) with a LEGACY `docmost:meta` fallback for migration. 6 unit tests; engine
suite green. Not yet wired into pull/push — no behavior change. Design doc

feat(git-sync): phase 2a — folder-note layout (parent -> Folder/Folder.md) 8c42c4f0d6

Native-Obsidian structure: a page WITH children now lives at its folder-note
<name>/<name>.md (LostPaul Folder Notes convention) with its children alongside;
a leaf stays <name>.md. Folder-notes claim their canonical path before a
same-named child, so the child (a leaf) is the one disambiguated, never the
folder-note — a folder X/ always contains its own note X.

Format-agnostic and safe in isolation: only the destination PATH changes, the
file content/serialization is untouched, so an existing parent relocates via the
move-by-id path (no delete). The frontmatter format flip (pull+push) is next.

6 new layout unit tests (leaf / parent / nested / child-named-as-parent /
twin-parents / childless). 611 engine tests green.

feat(git-sync): phase 2b — PULL writes native gitmost_id frontmatter 73c5c44301

PULL now serializes each page as the native-Obsidian format (serializePageFile:
a minimal gitmost_id frontmatter + the fixpoint markdown body) instead of the
heavy docmost:meta envelope. title/parent/space are derived (filename / folder /
repo), so only the pageId is persisted. readExisting recovers identity from the
gitmost_id frontmatter (parsePageFile) instead of docmost:meta.

Extracted stabilizePageBody() (the export->import->export fixpoint, no meta) so
the native writer and the legacy serializer share the same deterministic body —
re-pulls of an unchanged page stay byte-identical (loop-guard).

Tests: read-existing fixtures rewritten to gitmost_id; apply-pull asserts the
written text is native frontmatter and carries NO docmost:meta (regression
guard). 611 engine tests green.

NOTE: PUSH still reads docmost:meta — the end-to-end cycle is intentionally NOT
runnable until phase 3 (PUSH reads frontmatter + derives title/parent from path)
lands; no vault is wiped/deployed until then.

feat(git-sync): phase 3 — PUSH reads native gitmost_id + derives title/parent from path d255afa611

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.

docs(git-sync): mark thin-meta phases 2 + 3 done in the plan 6baad935f9

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

fix(git-sync): screen non-page files out of PUSH (CRITICAL — review) f6d22a59a6

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).

fix(git-sync): git-http stream error handlers + close test gaps (#119 review) 2e83c9cebf

Addresses the stability + test-coverage warnings from the #119 review:

- git-http-backend.service.ts: add `'error'` handlers to child.stdout/stderr. An
  EventEmitter 'error' with no listener (e.g. EPIPE when the client aborts
  mid-response) is rethrown by Node as an uncaught exception and crashes the
  process; now swallowed + logged (never echoed to the client).
- TEST INFRA: a jest setupFile shims `navigator`/`MessageChannel` for the `node`
  testEnvironment. react-dom@18 reads `navigator` at module-init (pulled in via
  @docmost/editor-ext -> @tiptap/react), so every spec transitively importing the
  conversion engine — including git-http.service.spec.ts — previously FAILED TO
  LOAD ("navigator is not defined") and ran ZERO tests. With the shim those specs
  now run (git-sync integration: 11 suites / 133 tests green).
- git-http.service.spec.ts: cover the 503 lock-held push path — `ingestExternalPush`
  rejecting `GitSyncLockHeldError` -> 503 + Retry-After + "git-sync busy, retry",
  no double header write (+ the already-headers-sent no-rewrite path).
- git-http-backend.service.spec.ts: unit-test run() — child 'error'/'close' before
  headers -> 500; normal CGI parse+stream; stdout/stderr 'error' (EPIPE) swallowed;
  synchronous spawn throw -> 500.
- page-change.listener.ts: implement OnModuleDestroy to clearTimeout all pending
  debounce timers on shutdown (+ test).
- .env.example: vaults are non-bare working repos, not "bare repos".

test(git-sync): add missing DTO/User imports for the rebased git-sync provenance spec block 3a91e0eca9

The rebase folded develop's agent-provenance PageService spec and the git-sync
provenance spec into one file; the appended git-sync block needs CreatePageDto /
UpdatePageDto / User imports that develop's spec (which used inline `as any`) did
not have. Server tsc + the suite (158 tests, both provenance blocks) green.

refactor(git-sync): internalize the engine — first-class ESM, no vendoring bridge (#119 review) 5da12e89f9

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).

chore(mcp): drop build/ + node_modules leftovers after rebase 52959de2f3

These files (build/lib/footnote-analyze.js, build/lib/footnote-lex.js from the
merged footnote work, and the y-prosemirror node_modules symlink) survived the
rebase because this branch's earlier "stop committing build/ and node_modules"
commit predated them. They are gitignored (packages/mcp/build/) and generated /
symlinked, so untrack them to keep the branch consistent with that decision.

fix(git-sync): address PR #119 review (#1571 ) 28d2560dfd

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.

fix(git-sync): red-team hardening — 12 confirmed sync-breaking bugs + regression tests d5079aa1d8

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
  ![](src). 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.

docs(git-sync): document GIT_SYNC_BACKEND_TIMEOUT_MS, drop dead consts, fix dangling plan refs 81c0226be7

Address the non-red-team documentation/cleanup items from review #1679:
- Document the GIT_SYNC_BACKEND_TIMEOUT_MS watchdog (git http-backend) in
  .env.example and add it to the environment validation schema — it was used
  (getGitSyncBackendTimeoutMs, default 120000) but undocumented/unvalidated.
- Remove the dead GIT_SYNC_DEBOUNCE_MS_DEFAULT / GIT_SYNC_POLL_INTERVAL_MS_DEFAULT
  exports (never imported; environment.service is the single source of defaults).
- Redirect the dangling `plan §X.Y` comment references to issue #194 (the
  git-sync spec moved there when docs/git-sync-plan.md was deleted by this PR).

feat(git-sync): per-space toggle for conflict-marker handling on push (#13 ) a40a00d5c5

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.

fix(git-sync): don't run a Docmost cycle on receive-pack info/refs (fixes deterministic push 503) 452a752264

A git push is a two-request exchange: GET info/refs?service=git-receive-pack
(ref advertisement) then POST git-receive-pack (the pack). The git-HTTP host
classified BOTH as serviceKind 'write' and routed both through
ingestExternalPush, which takes the per-space lock and runs a FULL Docmost
reconcile cycle. So the read-only info/refs advertisement held the lock while a
cycle ran, and the client's immediately-following POST git-receive-pack collided
with that still-running cycle and got 503 — deterministically, every push (and
Obsidian Git's "scan" failed for the same reason, since it probes push
capability via the same receive-pack info/refs).

Fix: only the actual pack-receiving write (POST git-receive-pack) runs under the
lock + cycle. Everything else streams the http-backend directly with no lock and
no cycle — a fetch/clone (read) AND the write-AUTHORIZED but read-only
info/refs?service=git-receive-pack advertisement. Authz is unchanged (the gate
still requires write permission for receive-pack refs); only the side effect of
running a cycle on a read-only request is removed.

Verified end-to-end on a live stand: clone, then `git push` of a new file lands
the page in Docmost (was 503 on every push before). Regression test added.

fix(git-sync): subpages round-trips (was {{SUBPAGES}} literal) + exhaustive all-node round-trip test 5125296bfa

subpages exported to the literal `{{SUBPAGES}}`, which has no markdown/HTML
inverse, so on re-import it came back as a plain paragraph holding the visible
text "{{SUBPAGES}}" — the embed rendered as that literal string on the page
after a sync (round-trip data loss, seen live). It now emits the schema-matching
`<div data-type="subpages">` like every other embed node, so the schema's
parseHTML rebuilds the subpages node. Also dropped the leaf-atom content-hole
in the subpages renderHTML.

New committed regression coverage:
- packages/git-sync/test/roundtrip-all-nodes.test.ts — exhaustive serialize ->
  deserialize round trip for ALL 40 node/mark types; each asserts the node/mark
  survives and no `{{...}}` literal leaks. This is the test that caught subpages.
- §13.1 gate (git-sync-converter-gate.spec.ts): subpages added to the green
  corpus (round-trips through the REAL server schema).
- Corrected two PR-authored tests that asserted the old {{SUBPAGES}} loss as
  "by design" — they now assert the fixed round trip.

Also folds in review #1679 coverage-gap tests (no prod change): orchestrator
pollTick/enabledSpaces, datasource 3-way merge dispatch, page.repo
last_updated_source provenance SQL.

git-sync vitest 659 (+1 expected-fail), server tsc clean, server specs green.

fix(git-sync): preserve subpages.recursive and details.open on round trip abd6e3948b

Found proactively by deepening the round-trip test from node-TYPE survival to
ATTRIBUTE fidelity (distinctive attr values per node). Two real losses (the
other 3 candidates — mathInline/mathBlock/pageEmbed — were verified to be
correct; the probe had used wrong attr names):

- subpages `recursive`: the converter emitted a bare div and the schema mirror
  didn't model the attr, so a recursive subpages reverted to non-recursive on a
  round trip. Now emits `data-recursive="true"` and the mirror parses it back
  (matching @docmost/editor-ext).
- details `open`: the `open` (collapsed/expanded) state lives on the details
  node, but the converter emitted the `<details>` wrapper from the summary case
  without it, so the state was dropped. The wrapper now carries `open`.

The round-trip test now also asserts attribute fidelity (12 cases) so these are
locked. Schema-surface snapshot updated for the new subpages attr.

git-sync vitest 671 (+1 expected-fail), §13.1 gate 27.

feat(git-sync): remove the per-cycle delete cap; deletes apply + are logged every cycle e777ebcf4f

The delete cap (GIT_SYNC_MAX_DELETES_PER_CYCLE, default 5) was a defense-in-depth
guard that SUPPRESSED a cycle's deletions when the planned count exceeded the
limit. In practice it was a crutch over engine correctness that also blocked
legitimate deletes: deleting a folder with many child pages is a normal action,
and git-sync deletes are SOFT (Trash, reversible), so a blocking limit has little
upside and real downside. There is also no user-facing surface to "confirm" a
large delete from a background sync — the only channel is the operator log.

So: drop the cap entirely. Deletes apply unconditionally; every cycle already
logs its full push plan, per-action `delete: <pageId>` lines, and completion
counts through the engine `log`, so what was deleted (and what was skipped) is
always recorded. Engine correctness (the reconcile/layout/round-trip tests) is
what prevents phantom deletions — not a blocking cap.

Removed: orchestrator `resolveApplyClient` cap hook + `maxDeletes`,
`getGitSyncMaxDeletesPerCycle`, the `GIT_SYNC_MAX_DELETES_PER_CYCLE` env/validation/.env.example,
and the cap tests. (The engine's generic optional `resolveApplyClient` hook is
left as an unused extension point.)

server tsc clean, git-sync + environment jest 174.

feat(git-sync): Obsidian-native callouts (> [!type]) instead of :::type b5ce63a956

Callouts now export as Obsidian's blockquote-callout syntax — `> [!type]` opener
plus a `>`-prefixed body — so they render as real callouts when the vault is
opened in Obsidian, instead of `:::type` (Docusaurus-style) which Obsidian shows
as a plain blockquote.

- Export (markdown-converter `case "callout"`): `> [!type]` + each body line
  blockquote-prefixed (a blank line becomes a bare `>` so the callout is not
  split). Nested callouts naturally become `> > [!type]`.
- Import (preprocessCallouts): a new branch recognizes `> [!type]` openers and
  the contiguous `>`-prefixed body, strips one blockquote level and recurses (so
  nested callouts work), emitting the same callout div the `:::` path produces.
  The legacy `:::type` parser is KEPT so existing vaults keep importing. A plain
  blockquote (no `[!type]`) stays a blockquote.

Tests: 4 converter golden tests updated to the new `> [!type]` output; 4 new
import tests (simple, nested, round-trip, plain-blockquote-untouched). The §13.1
gate still round-trips callout losslessly through the real server schema.
git-sync vitest 675 (+1 expected-fail), gate 27.

fix(git-sync): idempotent first-block reconciliation — stop start-of-doc content duplicating every sync cycle 2594828758

The block-level body merge keyed each block by its full attribute set,
including the per-block UniqueID the editor stamps on every heading/paragraph.
A body arriving from git is parsed from clean markdown and carries no block
ids, so a live block (id present) never matched the same block coming from git
(no id). The three-way merge's LCS could not anchor on it, and an incoming
block with no matching anchor — content inserted at the TOP of the page — was
re-added on every push/pull cycle: a non-convergent, unbounded duplication loop.

Exclude the volatile 'id' attribute from the block comparison key
(serializeXmlNode) so blocks compare by content across the git round-trip.
The merge keeps the live block INSTANCE (and its id, and any in-flight edit)
for an anchor — picks are by index, not key — so identity is preserved while
reconciliation becomes idempotent. Mirrors canonicalize.ts, which already
strips the regenerated block id from the round-trip idempotency comparison.

Adds a RED-before-fix repro modelling the live-id vs git-no-id asymmetry and
asserting no block growth across cycles.

fix(git-sync): converge git-ingest with open editor sessions — stop silent revert/data-loss on live pages 9e69d917ee

A git push to a page with an OPEN editor was silently reverted: the git
commit landed and the DB body updated, but the page in the browser stayed
on the old content and the editor's next autosave overwrote the git change.

Root cause (distributed, not in the merge): writeBody applied the body
merge via collabGateway.openDirectConnection on whichever instance/process
runs git-sync (the api/worker). When an editor is connected to a DIFFERENT
collab instance/process, that opens a SEPARATE, detached Y.Doc. The merge
landed in the detached doc + DB, but the live editor's Y.Doc never received
the Yjs update; its debounced autosave then persisted its STALE state over
the DB, reverting the git change (and, for concurrent edits to different
paragraphs, losing the git side). In one process the bug is invisible
because the direct connection already shares the editor's doc.

Fix: route the body write through the existing custom-event channel (the
same mechanism comment-marks and updatePageContent use) so the merge runs
on the instance that OWNS the live doc. Its update is then broadcast to
every connection (Document.handleUpdate) and the editor's CRDT converges on
the merged result. New CollaborationGateway.writePageBody dispatches to a
new gitSyncWriteBody handler (builds incoming/base docs before opening the
connection — crash-safe — then 3-way/2-way merges into the live fragment);
without redis it runs locally on the single (owning) instance. writeBody
now just forwards the converted ProseMirror bodies + service userId.

Evidence:
- git-ingest-convergence.spec.ts: deterministic two-Y.Doc repro. PATH B
  (undelivered update) asserts the LOSS (the bug); PATH A (update delivered,
  as the owner-routed write does) asserts the git change SURVIVES and that
  concurrent edits to different paragraphs both survive.
- collaboration.handler.git-sync.spec.ts: exercises the real gitSyncWriteBody
  against a shared doc wired to a connected "editor" doc (models the
  owning-instance broadcast) — editor converges, concurrent edit preserved,
  crash-safe on transform failure.
- gitmost-datasource.service.spec.ts: writeBody now routes via writePageBody
  (RED before this change — it called openDirectConnection).

Honest scope: the failure is cross-instance; full multi-instance convergence
needs a live Hocuspocus + redis and is not provable in a unit test, so the
convergence invariant is captured at the Yjs update-exchange level.

fix(git-sync): propagate remote custom-event handler errors instead of 30s timeout daf6c9ea16

When a git-sync body write (gitSyncWriteBody) is routed to the collab instance
that owns the doc, the handler runs remotely inside handleRedisMessage and CAN
throw (markdown->ProseMirror transform). Previously the throw was uncaught: the
customEventComplete reply was never published, so the origin's writePageBody
promise only rejected after customEventTTL (~30s) as a generic 'TIMEOUT', and an
unhandledRejection escaped the async messageBuffer listener on the owning
instance.

Now the owner wraps handleEventLocally in try/catch and, on throw, publishes a
customEventComplete carrying an `error` field on the same correlation channel.
The origin's pendingReplies holds {resolve, reject} and rejects promptly with the
real Error. The TTL TIMEOUT remains as the fallback for a genuinely lost reply.
The no-throw and local (same-instance) paths are unchanged.

fix(git-sync): make reconcile import truly idempotent — stop runaway whole-body duplication 857a0064f7

The live Yjs document materializes the editor-schema default `indent: 0` on
every paragraph/heading (and on the paragraph inside every list item, callout,
and table cell), but a body re-imported from git — parsed from clean markdown —
carries no indent attribute. So every live block's merge key differed from the
same block coming back from git: the three-way merge could anchor on nothing,
and the trailing unit that git's export already contained (but the merge could
not match against the byte-identical live tail) was re-appended on every
reconcile cycle. Each grown export then diverged from the last-pushed base by one
more unit — a self-sustaining, unbounded whole-body duplication loop with no
client connected.

The prior fix (0c7b73f7) excluded the volatile block `id` from the key, which
was necessary but not sufficient: `indent: 0` is a CONTENT attribute the editor
stamps as a default, so it was never stripped. Normalize editor-materialized
schema defaults (`indent: 0`) out of the block key — only the default value, so a
genuine `indent: 2` still diffs and lands — so a live block compares equal to its
git-round-tripped twin and the resync is a true no-op.

Regression test (yjs-body-merge.idempotency.spec.ts) encodes the invariant on a
body of byte-identical units (heading + paragraph + callout + table with empty
cells): a live fragment carrying indent:0 + ids merged against the git-derived
fragment (neither) with a stale-by-one base applies 0 ops and does not grow — RED
before, GREEN after.

fix(git-sync): normalize merge key against schema defaults — cover all node/mark default-attr duplication triggers (image, link, highlight, …) 42e618ec7f

The point-fix (7a7b840e) excluded only `indent: 0` via a hardcoded one-attribute
denylist (`DEFAULT_KEY_ATTRS`) applied solely to ELEMENT attributes. The same
divergence recurs for every attribute whose editor-ext (server) schema default the
LIVE Yjs doc materializes (`TiptapTransformer.toYdoc(tiptapExtensions)`) but the
git round-trip does not: the engine's `markdownToProseMirror` emits those attrs as
explicit `null` (verified live: link mark `internal: null`, heading/paragraph
`indent: null`), which `y-prosemirror` then drops — so the same block keys
differently on the two sides, the three-way merge anchors on nothing, and the body
is re-appended every reconcile cycle (unbounded, no client connected). The denylist
also could not reach MARK attributes at all (marks are serialized raw in the
XmlText delta), so the link mark's `internal` mismatch survived.

Replace the denylist with a normalization derived from the ACTUAL ProseMirror
schema (`getSchema(tiptapExtensions)`, memoized): in `serializeXmlNode`, drop any
ELEMENT attribute whose value equals its node's schema default (or is
null/undefined), and normalize each XmlText delta op's MARK attributes the same way
against `schema.marks[name].spec.attrs`. The volatile block `id` stays excluded and
genuine non-default values (a real `indent: 2`, `align: "left"`, `link.href`,
highlight color) stay in the key. This is general — it covers indent, image.align,
link.internal, highlight.colorName, youtube/pdf and any future node/mark — not
another per-attribute denylist. Schema build is wrapped so a degenerate test stub
(`tiptapExtensions: []`) degrades to dropping only null/undefined.

Tests: new `yjs-body-merge.schema-defaults.spec.ts` models image/link/highlight
both hand-built and through the REAL `TiptapTransformer.toYdoc` materialization
(live defaults vs engine-style explicit nulls, base stale-by-one) — RED before
(4 ops / growth), GREEN after (0 ops). Existing idempotency + open-editor
convergence suites still pass (261 server collab+git-sync tests, tsc clean).

fix(git-sync): propagate nested details open; drop dead delete-cap wiring; cover lost-lock abort + lose-prone atom round-trips e48d7720e9

Addresses review 1863 (delta) on PR #119.

MUST-FIX:
- detailsToHtml (the raw-HTML path used for a details nested inside
  columns/spanned cells) now emits `<details${open}>`, mirroring the
  top-level case, so `open` no longer silently drops every round trip.
- Remove the dead `resolveApplyClient` delete-cap hook from the engine
  `runCycle`: the orchestrator stopped passing it, so the hook + its
  dry-run pass were inert. Deletes are soft (Trash) + always logged and
  engine convergence is the guard, so no cap is re-added — just the dead
  wiring removed.

TEST COVERAGE:
- space-lock: heartbeat refresh CAS-miss (eval -> 0) and Redis-error
  (eval throws) both abort the in-flight fn's signal.
- cycle: a pre-aborted signal (and an abort during the pull read) throws
  before the push apply / first destructive phase.
- converter: htmlEmbed source VALUE + height survive; encode/decode
  UTF-8 symmetry and '' -> ''; footnote definition body + ref/def id
  match; transclusionReference both ids survive; fix the bad
  transclusionSource fixture (wrong `pageId` attr + empty content ->
  schema `id` + a block child); nested details `open` parity test.
- orchestrator: autoMergeConflicts:true reaches engine settings; default
  false on a missing settings row.

test(git-sync): mock db.transaction in movePage provenance specs eefe17600c

After rebasing onto develop, movePage runs its cycle-check + UPDATE inside
executeTx(this.db) (develop #207 advisory-lock/atomic cycle-guard). The
git-sync provenance specs still passed a bare `{}` db, so executeTx hit
`db.transaction is not a function`. Reuse the same trxStub Proxy + transaction
mock the develop movePage specs use so both the advisory-lock `sql.execute(trx)`
and updatePage resolve. Production movePage keeps BOTH develop's lock/cycle
guard AND git-sync's provenance stamping; this only updates the test harness.

fix(git-sync): unwedge per-page conflicts, preserve callout types, flush collab on disconnect fe4adf23a0

Addresses QA findings on PR #119 (issues #235/#236).

SYNC-WEDGE (HIGH): one same-line conflict on one page froze sync for the
WHOLE space in both directions forever. The pull's docmost->main merge left
the vault mid-merge, so every later cycle's isMergeInProgress() check returned
skipped:"merge-in-progress" and skipped the entire space with no recovery.
- pull.ts now COMMITS a conflicting merge with markers in place (commitMerge):
  cleanly-merged pages land, the conflicted page carries its markers on main and
  is isolated by the existing push-side conflict-marker skip (markers never reach
  Docmost), and the next cycle is no longer wedged. conflictedPaths is surfaced.
- cycle.ts now RECOVERS a vault left mid-merge by a prior/pre-fix cycle: it
  aborts the stale merge (merge --abort, hard-reset fallback) and continues,
  instead of skipping the space forever.
- git.ts: listUnmergedPaths / commitMerge / abortMerge / resetHardToHead.

CALLOUT TYPE FIDELITY: git-sync's CALLOUT_TYPES was missing "note" and "default"
(editor-canonical types), so [!note]/[!default] callouts flattened to [!info] on
every round-trip. Aligned the list with @docmost/editor-ext getValidCalloutType.

LOSS-ON-FAST-CLOSE: editing a page then closing the tab inside the collab
debounce window (~3-18s) lost the edit, because with unloadImmediately:false
Hocuspocus does not flush the debounced onStoreDocument on the last-client
disconnect. PersistenceExtension.onDisconnect now flushes the pending store
(debouncer.executeNow) on the last disconnect only, with no redundant write.

DUPLICATION re-verify (#1): the schema-default merge-key normalization is intact;
faithful toYdoc-based reproduction shows callout + rich content resync with 0 ops
and no growth/strip across cycles -> the re-report was leftover vault data, not a
live regression. Locked with a callout regression spec.

Tests: git-sync 688 pass (incl. real-VaultGit wedge-recovery integration); server
git-sync+collaboration 285 pass; new callout merge/fidelity + onDisconnect-flush
specs. tsc --noEmit clean.

fix(git-sync): address PR #119 review — close 403/404 space-existence leak + warnings/tests/arch 7179f8a5b2

Security (must-fix):
- /git smart-HTTP gate: an authenticated NON-member of a git-sync space now gets
  404 (not 403), so the 403<->404 difference can no longer be used to brute-force
  which spaces exist / have git-sync enabled. 403 is reserved for a MEMBER who
  lacks the required role (existence already known). New gate input
  userIsSpaceMember; decision-table + service specs extended.

Config (must-fix):
- Remove the dead GIT_SYNC_SSH_KEY_PATH knob (getter + validation field + two
  .env.example lines) — it had zero consumers and advertised a nonexistent push
  capability.

Stability/docs (warnings):
- Wire the lost-lock AbortSignal into runReceivePack -> git http-backend so the
  receive-pack child is killed if the per-space lock lapses mid-write.
- Raise the divergent-`docmost` (invariant §5) push refusal from info -> warn and
  surface divergentDocmost in the run status (/status).
- Comment the stale read-after-debounced-collab-write updatedAt in
  importPageMarkdown (deferred §10 loop-guard must not trust it).
- Fix the Dockerfile comment: the loader uses require.resolve + dynamic import(),
  it deliberately does NOT require('@docmost/git-sync').
- Merge the two near-identical space toggle handlers into one parameterized
  handler; add the 2 missing en-US i18n keys for the auto-merge switch (ru-RU not
  maintained for these git-sync strings, mirrored).

Tests:
- isGitSyncHttpEnabled() default-branch (unset -> isGitSyncEnabled fallback).
- agentSourceFields 'git-sync' case (source stamped, chat key omitted).
- editor-ext name-level schema contract (vendored mirror superset of editor-ext
  node/mark types) + the new shared resolver + non-member 404 gate cases.

Architecture:
- Extract resolveRequestWorkspace shared by DomainMiddleware + GitHttpService
  (the two real self-hosted/cloud copies; McpService has no cloud branch).
- Document the in-process setInterval multi-replica limitation + BullMQ/fencing
  future direction (deferred, not implemented).

fix(git-sync): address PR #119 review #2 — throttle /git Basic auth, fix mcp schema drift + warnings/tests 22e3fcdeba

Must-fix:
- Throttle the raw /git HTTP-Basic path: it bypasses Nest/ThrottlerGuard, so
  verifyUserCredentials (bcrypt) ran unthrottled. Wrap it in the SAME
  FailedLoginLimiter the /mcp path uses (5/60s; per-IP, per-IP+email, global
  per-email keys; atomic tryReserve BEFORE bcrypt; success resets, non-credential
  errors release). The (threshold+1)-th attempt now gets 429 pre-bcrypt. Sweep
  timer + onModuleDestroy mirror McpService.
- Fix the mcp schema mirror drift: packages/mcp details `open` attr now reads via
  hasAttribute (matches editor-ext canon + git-sync copy); getAttribute dropped a
  bare `<details open>` state. (build/ is gitignored — rebuilt locally.)

Tests added:
- /git brute-force throttle: pre-bcrypt 429 on the 6th failure; success resets;
  non-credential error releases the budget.
- git-http-backend lost-lock AbortSignal: already-aborted -> no spawn + 500;
  live abort mid-request -> SIGTERM + response closed.
- orchestrator divergentDocmost -> WARN + flag surfaced in status (+ clean case).
- pollTick re-entrancy guard skips an overlapping tick.
- datasource NotFound early-throws (getPageJson/move/rename) + updatedAt:undefined
  stale-read branch (importPageMarkdown/createPage).

Suggestions:
- space.repo updateGitSyncSettings: parameterize the jsonb key (`${prefKey}::text`)
  instead of sql.raw (latent-injection footgun); value stays sql.lit. Spec updated.
- pollTick re-entrancy guard (private `polling` flag).
- page-change.listener docstring: honest about the move/rename/delete over-skip
  (loop-guard keys only on lastUpdatedSource) -> ~poll-interval latency, not loss.
- AGENTS.md: document the root /git smart-HTTP route + GitSyncModule.
- Remove redundant redteam-provenance.spec.ts (covered e2e in
  persistence.extension.spec.ts:145).
- Extract the duplicated SIGTERM->SIGKILL+finish block (watchdog + abort) into
  terminateChild; centralize watchdog-timer teardown in done().

Architecture (deferred, documented): mcp schema header now carries the three-copy
keep-in-sync + schema-core note; the editor-ext contract test documents that the
mcp copy and attribute-behaviour drift (details `open`) are not mechanically
covered yet.

refactor(git-sync): address PR #119 review #3 — honest gitRemote scaffolding comments, env example, shared ESM bridge f020739bfd

1. gitRemote is NOT yet consumed (the vendored engine has no remote-push path,
   SPEC §7). Corrected the buildSettings docstring (it wrongly called gitRemote
   "load-bearing") and marked the env -> validation -> getter -> buildSettings
   chain as inert SCAFFOLDING for the deferred remote-push feature at all three
   sites. Kept the wiring (harmless; removing only churns).

2. .env.example: document that GIT_SYNC_REMOTE_TEMPLATE substitutes the literal
   "{spaceId}" per-space (with the example), so an operator doesn't point every
   space at one remote.

3. Extracted the copy-pasted CJS->ESM dynamic-import bridge
   (`new Function('s','return import(s)')`) into one shared
   common/helpers/esm-import.ts; git-sync.loader, docmost-client.loader and
   mcp.service now import it and keep their own typed loadX() wrappers.

Deferred (notes only, not implemented):
- lcs.ts + three-way-merge.ts could move into packages/git-sync, but that engine
  is vendored (manual re-sync) — added a one-line note at three-way-merge.ts to
  revisit once the re-sync story is settled.
- schema-core single source + BullMQ/fencing remain documented from prior rounds.

fix(git-sync): address PR #119 review #4 — symlink guard, dead-code cull, changelog + warnings/suggestions 906733b5c8

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).

fix(git-sync): push 503 starvation + concurrent-edit marker leak/silent loss b7e5cb6970

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.

fix(git-sync): kill spurious marker-leaking conflict, concurrent-edit loss, flapping HEAD b47751349f

Three more git-sync QA defects from the 2nd live pass on PR #119, plus a
callout-fidelity nit:

1. SPURIOUS conflict leaked raw markers into canonical main (root cause). On an
   ordinary round-trip the only difference between the docmost mirror (normalize-
   on-write) and a user's raw push is trailing/empty-line normalization, which made
   git's line-based docmost->main merge CONFLICT, and the wedge fix then committed
   the file WITH literal <<<<<<< / ======= / >>>>>>> markers onto main (git and the
   DB silently diverged for cycles). Fix: on a conflict, normalize trailing/empty
   lines on BOTH sides (showStage :2:/:3:) before comparing — a trailing-only diff
   is recognized as spurious and resolved to the clean normalized form. A GENUINE
   same-block conflict is auto-resolved to OURS (git wins, mirroring the live-doc
   3-way rule); the docmost side stays on the `docmost` branch + page history. Raw
   markers NEVER reach main again.

2. Concurrent UI<->git edit silently lost the UI side. The git->Docmost 3-way merge
   ran against a live Y.Doc that hadn't yet received the user's debounced in-flight
   edit, so git clean-applied (no conflict detected) and the edit vanished even on a
   different block. Fix: flush the pending debounced store before the merge so the
   in-flight edit is drained into the live doc first — a different-block edit is
   merged, a same-block one is detected and pinned to history (recoverable).

3. Smart-HTTP HEAD flapped to the read-only `docmost` mirror (~1/4 of clones). The
   engine transiently checks out `docmost` mid-pull and the host advertises whatever
   HEAD resolves to. Fix: VaultGit.pinHeadToMain(); the cycle restores HEAD->main in
   a finally; and the upload-pack ref advertisement is served HEAD-pinned under the
   per-space lock so it can never observe a mid-cycle HEAD.

4. (callout) clampCalloutType now mirrors the editor's GITHUB_ALERT_TYPE_MAP for
   non-schema aliases (tip->success, caution->danger, important->info) instead of
   flatly collapsing to info. The editor schema genuinely supports only the six
   banner types, so unknown types still fall back to info (by design).

Tests: deterministic real-git trailing-blank round-trip (no conflict, no markers,
in sync over 2 cycles) + genuine-conflict no-marker-leak; HEAD advertisement
stability; pre/post-flush concurrent-edit survival; serveReadAdvertisement lock
pin; widened callout-alias coverage. Engine vitest + server tsc + collaboration /
git-http / orchestrator specs all green.

test(git-sync): cover null-edge conflict resolution in applyPullActions (F1) 32cb9eb1e3

The genuine-conflict branch in applyPullActions resolves to `ours ?? theirs`,
but the two stages where a side is ABSENT had NO test — the existing conflict
tests only fed stages where both ours and theirs are non-null. This is the
data-preservation core on the published `main`: a regression (dropping the
`?? theirs`, or wrongly writing on both-null) would silently lose a surviving
Docmost edit or resurrect a both-deleted page.

Adds four tests:
- apply-pull-actions.test.ts (fake-git, controlled stages): modify/delete
  (ours=null, theirs!=null -> keep THEIRS) and delete/delete (both null ->
  write nothing, deletion staged by commitMerge's `git add -A`).
- pull-conflict-normalize.test.ts (real-git 3-way): modify/delete built by
  deleting on main + modifying on docmost (stage 2 absent -> theirs kept,
  committed clean, no markers); delete/delete built via a rename/rename(1to2)
  on the shared base file, which records the original path as both-deleted
  (stages 2 AND 3 absent -> nothing written, deletion committed off main).

Production logic at pull.ts:487-497 held — pure test-coverage fix.

test(git-sync): accurate null-edge docstring + fill round placeholder (F2/F3) fbaaa84419

F2: the real-git modify/delete null-edge test docstring overclaimed it
caught loss of the `?? theirs` fallback end-to-end. git itself leaves
theirs in the working tree (stage 3) so commitMerge's `git add -A` would
stage it even with the bug — the assertions pass on broken logic. Reword
to state it verifies the clean-merge happy path; the real F1 regression
guard lives in the fake-fs apply-pull-actions.test.ts.

F3: fill the `round-?` placeholder with `round-2` in both new blocks to
match the file convention (header: 'QA #119 round-2').

Comment-only; no production or test-logic changes.

fix(git-sync): deliver body on rename+edit via honest 3-way merge; cover CREATE strip; fix env doc (F4-F6) 63f948df10

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.

    placed above computePushActions so the planner JSDoc stays attached.

fix(git-sync): round-trip the spoiler mark and image caption 7abce93543

After merging develop, git-sync's markdown converter still predated two
editor features and silently dropped them on every sync:

- Spoiler mark (#259): had no schema entry, so `<span data-spoiler>` from
  the canonical lossless form re-parsed as plain text and the mark was
  lost. Register a Spoiler mark mirroring @docmost/editor-ext + the MCP
  schema, and emit `<span data-spoiler="true">…</span>` on PM->MD.
- Image caption (#221): the converter assumed no caption attribute existed
  (the branch was dead). The image schema now carries a plain-text caption
  (data-caption); register it and route a captioned image through the raw
  <img> form (same lossless convention as the other Docmost image attrs).
  Caption-less images keep the lighter `![](src)` form.

Both survive PM->MD->PM unchanged; raw `<span data-spoiler>` / `<img
data-caption>` in incoming markdown parse back. New round-trip tests in
markdown-roundtrip-spoiler-caption.test.ts; schema-surface snapshot updated.

fix(git-sync): strip cosmetic ~<slugId> disambiguation suffix from ingested title 123e981808

Two sibling pages that share a title collide on one vault filename, so the
layout appends a cosmetic ` ~<slugId>` suffix (engine disambiguate()). That
suffix is a local filesystem artifact and must never become the page's real
Docmost title, but on ingest the filename-derived title carried it back into
the DB on some paths (observed: intermittent same-title collision left a page
permanently titled "Title ~<slugId>"). Strip it in renamePage() — the single
choke point every git-sync title write funnels through — but only when the
trailing token equals THIS page's own slugId, so a genuine user title that
legitimately ends in ` ~token` is never corrupted (slugId is a random nanoid).

Repro: create two pages with the same title; ~1 in 4 the second page's title
is permanently polluted. After fix: 0/6.

fix(git-sync): don't trash a page on cross-space move (move-to-space data loss) c7e034cab9

A page moved to another space with git-sync enabled was sent to Trash and
vanished from BOTH vaults. The source space's push phase sees the moved-away
page's file gone from its vault and calls deletePage -> soft-delete, even though
the page still lives in the destination space.

Thread the reconciling spaceId into the bind context and, in deletePage, skip the
soft-delete when the page's CURRENT space differs from the space being reconciled
(a move-out): only the vault file is dropped, the page is preserved. Genuine
in-space deletions are unaffected (space matches).

test(git-sync): fix #119 review F1-F4 (bind assert, cross-move + strip tests, comment) fcc9ae0c24

F1: git-sync.orchestrator.spec bind assertion now includes spaceId ('space-1'),
matching driveCycle's dataSource.bind({workspaceId,userId,spaceId}).
F2: add 4 non-vacuous tests for the cross-space move data-loss guard in deletePage
(CTX_SPACE with spaceId): move-out skips removePage (returns skipped:'moved-to-other-space');
same-space / not-found / already-deleted all still call removePage.
F3: add 2 tests for the ~<slugId> title-strip guard in renamePage (own slugId stripped;
a foreign ~<slugId> tail left intact).
F4: reword the gitmost-datasource 'single choke point' comment — the strip covers the
rename/update path, not every git-sync title write (createPage's filename-derived title
does not funnel through here).

fix(git-sync): make body ingest idempotent to stop idle churn + silent edit-revert (GS-EDIT-REVERT) f2d12fd2cd

On a git-sync space, a page's web edit was silently reverted within ~1 poll,
and idle spaces showed dozens of 'update' actions per cycle with no real change.

Root cause: the vault->Docmost body ingest (importPageMarkdown) is re-run every
poll for pages the upstream change-detection mis-flags as changed (the
markdown<->ProseMirror round-trip is not byte-stable: JSON key order / default
attrs differ though the content is identical). Each call re-imports the SAME body
into the live collab doc -- a no-op at idle, but it CLOBBERS a concurrent human
edit still in the debounced (not-yet-flushed) Yjs doc.

Fix: skip the ingest when it is genuinely a no-op --
  1) baseMarkdown byte-identical to the current file (vault unchanged), or
  2) the parsed incoming body is canonically-JSON-equal (key-order-insensitive)
     to the page's current Docmost content.
A real git-side change is neither, so legitimate git->Docmost ingests still apply.

Verified: idle churn 38 update/cycle -> 0; web edit on an affected page 0/3 -> 3/3
persisted; genuine git-side edit still ingests. Found by autonomous QA
(web-test-orchestrator) + independent verifier.

fix(git-sync): review #4404 batch — sanitize-title echo, per-space gate, move-echo, merge-agreement, fence-aware conflict scan, e2e asserts c838fdeebe

Addresses reviewer comment #4404 (critical + blocking):

- Critical #2: renamePage skips the echo where the incoming title equals
  sanitizeTitle(current title) — a Docmost title with FS-hostile chars (: / " |,
  newlines, double-space, >120) was pulled to a sanitized stem then written back,
  permanently corrupting the real title. (datasource)
- Blocking #3: runOnce enforces per-space settings.gitSync.enabled (the event
  path bypassed opt-in; any edited space would git-init + export). (orchestrator)
- Blocking #6: movePage no-ops the position-less same-parent echo that clobbered
  the user's chosen sibling order. (datasource)
- Blocking #9: hasConflictMarkers is fence-aware — '<<<<<<< HEAD' inside a code
  block (git-tutorial page) no longer trips the all-or-nothing gate that froze
  the whole space's refs. (push.ts)
- Blocking #11: three-way tryMergeRegion short-circuits when live==target (diff3
  agreement) instead of logging a false 'same-block conflict resolved to git' —
  the echo noise that masked real data-loss signals. (three-way-merge)
- Blocking #12/#13: e2e-advanced — drop the delete-cap block (no such feature;
  failed with a scary '(data loss!)'); non-member assert now expects 404 (existence
  not leaked), not 403.

Verified on stand: sanitized-title rename preserves DB title (vault file
sanitized); non-enabled space creates no vault; fenced conflict markers ingest
without jamming; build clean.

fix(git-sync): forward gzip encoding (#4 ) + catch read-advertise reject after hijack (#5 ); fix Export 500 on pages with inline comments f9cd3e6318

- Review #4: forward HTTP_CONTENT_ENCODING to git http-backend so it inflates
  gzip'd RPC bodies — a non-trivial `git pull` no longer fails with
  `fatal: expected 'packfile'`. (git-http-backend + git-http.service)
- Review #5: the read-advertisement branch runs under the space lock AFTER
  reply.hijack(); a reject there (e.g. Redis down) previously left the socket
  open forever, hanging every clone/fetch. Mirror the push branch: catch, 500 if
  unwritten, always end the socket. (git-http.service)
- GS-EXPORT-500 (QA): a page with an inline comment mark returned HTTP 500 on
  Export/copy-as-markdown. The Comment mark's renderHTML took the imperative
  document.createElement branch server-side (the DOM shim used by generateHTML
  defines window/document), returning a live node with no content hole that
  crashed prosemirror-model's DOMSerializer under happy-dom. Gate the imperative
  branch on a real browser (navigator.userAgent contains 'Mozilla'); the server
  now uses the static DOMOutputSpec form. Verified: export 200 (was 500).

fix(git-sync): round-trip paragraph/heading text alignment (review #10 ) bb5bb52244

Aligned paragraphs were exported as <div align="…"> which had NO matching
import parse rule — the div was unwrapped and the alignment lost on every
round trip. Emit a styled <p style="text-align:…"> instead, and give the
textAlign global attribute (docmost-schema) an explicit parseHTML that reads
element.style.textAlign (and legacy align=) plus a renderHTML that writes the
style. Now heading/paragraph alignment survives Docmost->git->Docmost.

Verified on stand: a textAlign=center paragraph exports as
<p style="text-align:center">, and after a git-side edit + re-import the
paragraph still has textAlign=center in the DB (was null before).

chore(git-sync): remove dead Settings REST fields, warn on inert REMOTE_TEMPLATE, fix stale docstrings (review) 91d674fea6

Dead code / doc-vs-code cleanup from review #4404:
- Drop the unused Settings.docmostApiUrl/Email/Password fields (the native
  in-process datasource never reads them; the engine only used docmostSpaceId).
  Removed from the type, buildSettings, and the 4 engine test suites that
  fabricated them.
- Warn ONCE at startup when GIT_SYNC_REMOTE_TEMPLATE is set — remote push is
  deferred (SPEC §7) so the value is currently inert; the operator now gets a
  log line instead of a silent no-op.
- Correct stale docstrings that claimed live-destructive code was 'FAKES only /
  NEXT increment / no live wiring' (applyPushActions runs LIVE via
  runCycle->orchestrator); that importPageMarkdown receives a 'self-contained
  file (meta+body)' (it receives the stripped body); and that the Yjs body merge
  is '2-way' (3-way runs end-to-end when the base is present).

No behavior change (except the new warning); build + git-sync smoke verified.

fix(git-sync): a git-revert of a page delete restores the page (review warning) 67fa0d1a28

A git-side revert of a delete commit re-adds the page's .md; the push classifier
saw an add carrying a known pageId and emitted an UPDATE, writing the body to the
still-trashed page. It stayed in Trash and the next pull re-deleted the file, so
the revert was silently nullified (permanent vault<->Docmost divergence). In
importPageMarkdown, if the target page is soft-deleted, restorePage() it first
(restorePage was already in the client seam but never called), then apply the
body — so a git revert actually brings the page back.

Verified on stand: git rm -> page trashed; git revert -> deleted_at cleared
(page restored).

fix(git-sync): honor a git-side page clear instead of diverging (review warning) edc5dae103

Clearing a page's body in git advanced the vault ref past the empty commit, but
the persistence store-side empty-guard rejected the empty write (reloading the
non-empty DB content) — so Docmost kept the old body while the vault held the
empty one, a permanent silent vault<->Docmost divergence that never re-detects.
A git-sync write is authoritative and its content IS the vault file, so an empty
incoming doc there is a DELIBERATE clear (no transient-glitch empties for a
file-sourced write). Allow it (lastUpdatedSource==='git-sync'), mirroring the
#251 intentional-clear allowance for the user-signalled source.

Verified on stand: a git-side body clear takes the page body 28 -> 0 (page not
trashed); previously it stayed 28 (diverged).

fix(git-sync): render tables as HTML inside columns (#7 ) and for multi-block cells (#8 ) 539512c4c8

Two table round-trip losses from review #4404:
- #7: a table inside a column was emitted as a GFM pipe table INSIDE the raw-HTML
  <div data-type="column"> wrapper. marked does not parse markdown inside a raw
  HTML block, so on re-import the table became literal "| a | b |" text.
- #8: a table cell holding block content (a list, code block, multiple paragraphs)
  only used the HTML <table> form when a cell had colspan/rowspan; otherwise the
  GFM pipe path flattened the cell's blocks onto one line and lost the structure.

Extract a shared tableToHtml() helper and use the HTML <table> form when: a cell
is merged (existing), a cell is multi-block (#8), OR the table is rendered in a
raw-HTML context — blockToHtml's table case now routes through tableToHtml (#7).

Verified on stand: a table-in-column exports as <table> inside data-type=column;
a cell with a bullet list exports as <table> with <ul><li>, and a git-side edit
+ re-import keeps the bulletList + both items in the DB content (was flattened).

test(collab): mechanical attribute-level schema contract (#293 ) 320b200ac8

The existing name-level contract (packages/git-sync schema-editor-ext-contract)
only compares node/mark TYPE NAMES, so a new attribute added to an existing node
upstream slips through and is silently dropped on every git-sync round trip -- a
repeatedly-hit data-loss class (image caption #221, paragraph align #10).

This closes the attribute gap by comparing the RESOLVED ProseMirror Schema
objects (getSchema has already merged all addGlobalAttributes spreads into
concrete per-node attrs) of the server's canonical tiptapExtensions vs the
git-sync mirror, asserting equal attribute-key sets per shared node/mark modulo
a committed, self-checking allowlist of the 6 understood divergences. A forgotten
attribute now fails CI loudly instead of losing data. Comparing resolved schemas
(not raw extension configs) is what makes this stable rather than the fragile
config-shape compare the name-level test deferred.

fix(git-sync): close #119 blockers — dead edit-revert guard, cross-space guard, red suite (F5/S2/G1/A1/F7) 5d45f5a85e

F5 (HIGH data-loss): guard #2 (GS-EDIT-REVERT) called a local key-sorting equality that
never matched a real page (block ids + materialized defaults differ), so the guard was
dead and a web edit on a git-sync space was silently reverted within one poll cycle. Use
the package's authoritative docsCanonicallyEqual (strips block id + normalizes
KNOWN_DEFAULTS), wired through the git-sync loader like sanitizeTitle; delete the dead
local canonicalize/canonicalJsonEqual.
S2 (security): importPageMarkdown targeted a page by the vault-file id without a spaceId
check (deletePage had one) — a space-A vault file carrying space-B's page id could
resurrect/overwrite/clear B's page. Mirror deletePage's guard: skip when the loaded page
lives in a different space than ctx.spaceId.
G1 (jest green): add sanitizeTitle + docsCanonicallyEqual to the loadGitSync mock; update
the converter-gate + package golden expectations to the genuinely-fixed output (paragraph
textAlign now round-trips, multi-block table cells emit HTML tables); fix the orchestrator
spec's stale mock so the per-space enabled gate (added later) is satisfied.
A1: the converter dropped heading textAlign on export (bare '## text'); emit a styled
<hN> when aligned, symmetric to paragraphs — round-trips losslessly (level + align), no
churn for unaligned headings.
F7 (docs): reword the false 'single choke point' title-strip comment; correct push.ts
docstrings that still described the removed standalone-CLI/daemon model.

Adds regression tests: the F5 acceptance test (canonically-equal content with real uuids
=> writePageBody NOT called), the S2 cross-space import guard, and the A1 heading
round-trip.

fix(git-sync): complete A1 heading alignment — green suite + nested path (on 5d45f5a8) 67dca8c10e

QA follow-up on 5d45f5a8: that commit taught the converter to export heading
textAlign (<hN style>) but left the converter-gate heading test still asserting
the OLD dropped behavior (expects a bare '## text'), so jest was RED — the G1
green-suite gate was not actually met. Two gaps closed:

1. Flip the heading KNOWN-DIVERGENCE gate test to assert the round trip now
   PRESERVES alignment (exported as <h2 style="text-align:center"> and recovered
   on import), matching the shipped converter behavior. Suite is green again.

2. blockToHtml (the nested-container path: heading/paragraph inside a
   column/table/callout) still emitted bare <hN>/<p>, dropping textAlign for
   nested blocks. Carry the style there too, symmetric with the processNode path.

Also add #7 (table inside a column) and #8 (multi-block table cell) to the
lossless round-trip CORPUS so both survive export->import through the real
editor-ext schema (columns widthMode pre-authored at its normalize fixpoint).

Verified: server jest 193 suites / 2142 tests green, git-sync vitest 704 green,
no type errors.

fix(git-sync): a malformed non-UUID gitmost_id no longer wedges a space's sync (C9-D1) f36a2def73

A vault file with a broken/hand-edited `gitmost_id` frontmatter (e.g.
`gitmost_id: [unclosed` or a non-uuid token) fed that value into a Postgres
`uuid` predicate (page update/delete), throwing 22P02 "invalid input syntax for
type uuid". The push apply recorded it as a per-cycle failure that never cleared —
refs never advance when failures>0, so the WHOLE space's sync looped on the same
failure indefinitely and no further legitimate change synced (found via web-test).

Wrap the id-scoped write ops (import/delete/move/rename/restore) at the bind()
seam: swallow exactly the 22P02 as an inert no-op so the cycle succeeds and the
rest of the space keeps syncing; re-throw anything else. pageId is the only
user-influenced uuid in these ops, so a 22P02 there unambiguously means it.

Verified on the stand: pushing a non-UUID gitmost_id now logs a skip warn and the
space stays at 0 failures (was 1 failure/cycle forever); a concurrent legit edit
to another page still syncs. Unit tests: import/delete swallow 22P02, non-22P02
re-throws. Full server suite green (2145).

fix(git-sync): a git edit that drops the gitmost_id frontmatter is no longer lost (C10-D1) cec50c3ce4

If a git-side edit rewrote a page file WITHOUT its `gitmost_id` frontmatter (e.g.
a tool that regenerates the whole file), the push planner's M (modify) branch found
no pageId in the current meta and SKIPPED the file — then the next Docmost->git push
overwrote it with the DB content, silently reverting the edit (data loss, found via
web-test).

Mirror the D (delete) branch: recover the identity from the PRE-IMAGE meta (the
last-pushed version at the same path, which still carried the id) before skipping,
and apply the body edit as an update. The pushed-back re-serialize restores the
frontmatter next cycle, so the file self-heals. Only when the pre-image ALSO lacks
an id (a never-tracked page) is it genuinely skipped.

Verified on the stand: editing a synced page's file with the frontmatter removed now
applies the edit (was reverted). Unit test: a modified file with no current pageId
recovers it from the pre-image -> update. git-sync suite green (705).

fix(git-sync): coerce malformed parentPageId to root in createPage/movePage (#119 F1) 5b835fc185

A non-UUID gitmost_id on a parent folder-note, used as parentPageId for a
git-sync createPage (or as a movePage destination), wedged the entire space:
the throw landed in `failures`, and push only advances refs when
failures.length === 0, so the space re-attempted forever.

createPage was the only user-influenced-uuid op left unguarded. The throw is a
NotFoundException, not a 22P02 error: PageRepo.findById falls back to a slugId
lookup for non-UUID input, finds no row, and PageService.create raises
NotFoundException — so skipIfMalformedId (22P02-only) would NOT have caught it.
Coerce-to-root is the correct fix: a non-UUID parentPageId is rewritten to root
(undefined/null) so the page is created/moved at the space root instead of
wedging. No data loss (page still created) and no duplication (push.ts writes
the assigned id back to frontmatter, so the next sync matches by id, and the
retry-adopt map re-parents once the vault id is fixed).

Applied to both createPage and movePage (the move destination is reachable via
two paths, one 22P02-swallowed-but-mislogged and one NotFound-wedging). The
child pageId stays guarded by skipIfMalformedId.

F2: softened the skipIfMalformedId comment (parentPageId is a second
user-influenced uuid in create/move) and made the swallow log op-generic.

fix(git-sync): a valid-but-nonexistent gitmost_id no longer wedges a space's sync (N1-D1) e6a861bdaf

A vault file whose `gitmost_id` is a WELL-FORMED UUID that matches no page (a stale
id from a restored-from-backup file, or a copied/foreign id) fell through
importPageMarkdown to writeBody() on a non-existent page, throwing "Page … not
found". The push apply recorded that as a per-cycle failure that never cleared —
refs never advance, so the whole space's sync looped on the failure indefinitely
(observed live: a leftover orphan file kept a space stuck at "1 failure" every ~5s).
Same user-visible impact as C9-D1, but the id is a valid uuid so the 22P02 guard
does not catch it.

Add the missing `currentPage == null` branch in importPageMarkdown: skip the
unknown id as an inert no-op so the cycle succeeds and the rest of the space keeps
syncing. Verified on the stand: pushing a valid-but-nonexistent gitmost_id now stays
at 0 failures (was 1/cycle forever), logs a skip warn, and a concurrent legit edit
still syncs. Unit test added; server suite green (2146).

NOTE (separate design follow-up, not this commit): the reconcile still cleans the
orphan file (it maps to no live page). ADOPTING such a file as a fresh page (the
restore-from-backup use case, preserving the git-authored content) needs the title
from the filename, which lives in the engine classifier, not this method.

fix(git-sync): correct stale S2-gate comment + drop vestigial currentPage narrowing (#119 F1) 8f7da77939

The N1-D1 fix added an early `return {}` when `currentPage == null` in
importPageMarkdown. `currentPage` is a const, never reassigned, so from that
guard onward it is provably non-null — which made the cross-space (S2) gate's
comment false ("a not-found page still proceeds as before": a not-found page
now returns early above) and left dead null-handling around it.

- Rewrite the S2-gate comment: the null case is handled by the N1-D1 guard
  above; here currentPage is guaranteed non-null. Confused-deputy / cross-space /
  mirror-deletePage explanation kept intact.
- Drop the dead `currentPage &&` conjunct from the S2 condition (always true).
- Collapse downstream vestigial `currentPage?.` / `currentPage!` / the
  `currentPage ? … : undefined` ternary to plain `currentPage.` — all
  behavior-preserving (currentPage non-null after the guard). The unrelated
  `page ? … : undefined` ternary (fresh findById that can be null) is untouched.

No runtime behavior change. jest gitmost-datasource.service.spec.ts: 34 passed.

fix(git-sync): self-heal a stale .git lock that wedged a space forever (D3-N3) f0778cb85a

An interrupted git operation (a hard crash / OOM-kill / abrupt container stop mid
`git add`/`commit`/`checkout`) leaves a `.git/index.lock` (or a ref `*.lock`).
Git then refuses EVERY subsequent operation ("Unable to create '…/index.lock':
File exists"), so every poll cycle failed and the space's sync wedged INDEFINITELY
with no self-heal — the whole space stopped syncing until a human ran `rm` on the
lock (found via web-test restart/corruption charter, reproduced deterministically).

The daemon holds the per-space Redis lock and is the vault's ONLY writer, so any
`*.lock` reaching a fresh cycle is necessarily stale (no live git process holds it).
Add `VaultGit.clearStaleGitLocks()` and call it in the cycle preflight, right after
ensureRepo and before the mid-merge recovery — clearing index/HEAD/config/packed-refs/
MERGE_HEAD/ORIG_HEAD and the engine's ref locks (best-effort, missing = no-op).

Verified on the stand: a planted stale index.lock is now cleared and the space
recovers (edit reaches the vault, 0 "File exists" errors) — was wedged forever.
Unit test (real temp repo: index.lock blocks git add -> clear -> git add works);
git-sync suite green (707).

fix(git-sync): self-heal a missing 'main' branch that wedged a space (D3-N1) d218b3a39e

Ref-store damage (a deleted refs/heads/main, an interrupted ref update) can leave an
existing vault repo without a 'main' branch. The cycle's ensureBranch('docmost','main')
+ checkout then throw every poll ("pathspec 'main' did not match"), wedging the space
forever with no self-heal — ensureRepo only creates branches on a FRESH git init
(found via web-test corruption charter, reproduced deterministically).

Add VaultGit.ensureMainBranch() and call it in the cycle preflight (after
clearStaleGitLocks, before the branch setup): if 'main' is missing, re-create it from
the 'docmost' mirror branch (they track each other) else from HEAD. Same
wedge-forever family as D3-N3.

Verified on the stand: deleting refs/heads/main now self-heals (main restored, the
edit reaches the vault, 0 pathspec errors) — was wedged forever. Unit test (real temp
repo: delete main -> ensureMainBranch restores it from docmost). git-sync suite green (708).

fix(git-sync): gate stale-lock removal by mtime + cover preflight self-heals (#119 F1-F4) 3f7d96e09d

clearStaleGitLocks() removed a hardcoded list of 9 git lock files
UNCONDITIONALLY — despite its name it never checked staleness. In a
multi-replica TTL-lapse window (a documented engine limitation), replica B's
preflight could rm a LIVE index.lock held by replica A mid `git add`/`commit`,
turning a safe fail-fast ("index.lock: File exists") into concurrent
index/ref writes and corruption.

F1: gate each removal by file age. A live git op is bounded by
GIT_EXEC_TIMEOUT_MS (120s), after which git is killed and the lock's mtime
freezes — so a lock older than 3× that (STALE_LOCK_MIN_AGE_MS = 360s) provably
has no live holder and is a genuine crash-leftover. Fresh locks (mtime within
the window) are preserved; missing locks are a no-op. Strictly safer than the
prior unconditional rm (the gate can only prevent removals, never add them).

F4: move clearStaleGitLocks (doc + body) below isMergeInProgress so the
mid-merge jsdoc re-attaches to its real owner; soften the doc (it clears a
fixed list of the engine's own index/ref locks, not "any *.lock").

F2: cycle.test.ts pins the preflight order
ensureRepo < clearStaleGitLocks < ensureMainBranch < ensureBranch (a refactor
that moved clearStaleGitLocks before ensureRepo — deleting ensureRepo's own
transient lock — would now fail the test).

F3: git.test.ts covers ensureMainBranch's HEAD-fallback branch (both main and
docmost gone → main recreated from HEAD) and the no-commit no-op.

Also: the D3-N3 test now backdates the planted lock's mtime so it is stale (and
still removed), plus a new test asserts a FRESH lock is PRESERVED (the
corruption-safety property — this would fail against the old code). cycle.ts's
preflight comment softened to match the mtime gating.

git-sync vitest: 711 passed | 1 expected-fail (+4 new tests). tsc clean.

Merge develop into feat/git-sync to make #119 mergeable 7d9cf99f6c

Brings the git-sync epic up to current develop (79 commits) so it can land —
prerequisite for the #293 converter unification, which restructures git-sync.

Conflict resolutions:
- translation.json (en+ru): union of #119's git-sync keys and develop's agent
  keys; restored a ru-RU key develop had dropped so en/ru stay in parity.
- history-item.tsx: keep develop's AgentAvatarStack (the #300/#319/#320 avatar
  rework) AND #119's GitSyncBadge provenance branch; drop the superseded
  AiAgentBadge (and its now-unused component/test). Test updated to match.
- collaboration.handler.ts: keep #119's flushPendingStore (QA #119 pre-merge
  flush) AND develop's generic withYdocConnection<T> (the #315 closure-capture
  version) — git-sync callers pass sync void fns which <T=void> handles.
- comment.ts (editor-ext): take develop's isNodeRuntime SSR guard; it subsumes
  #119's isInteractiveBrowser/GS-EXPORT-500 fix (any Node render → static spec).

Build policy: honor #119's approved design — packages/{mcp,git-sync}/build are
gitignored and built in CI/Docker (Dockerfile pnpm build + COPY both), so
develop's committed build/ copies are removed from the index (no more src/build
drift). NOTE: after this merges, rebuild git-sync in any working checkout.

Verified: editor-ext 249/249, collaboration jest 204/204, page-history 13/13,
schema-attribute-contract + converter-gate 32/32; editor-ext/mcp/git-sync tsc
clean. The two residual apps/server tsc lines are the worktree node_modules
symlink resolving @docmost/git-sync to a stale sibling checkout, not a merge
defect (jest green).

Merge develop into feat/git-sync — unify converter on the branch (#293/#326 step 6a) e90624a51c

Per maintainer directive (#119 comment): land the canonical converter on the
git-sync branch so sync is tested on the real format, NOT a dead legacy copy.
#119 itself stays FROZEN (не вливается) — this only merges develop in.

Resolutions (all git-sync converter conflicts → develop; engine kept as-is):
- Dropped the branch's legacy `packages/git-sync/src/lib/*` converter — the
  converter now lives solely in `@docmost/prosemirror-markdown` (#293); the
  engine (pull/push/stabilize/index) only switches its imports to the package
  (no logic change, verified by diff).
- Removed the branch's orphaned converter tests + fixtures under
  `packages/git-sync/test/` (their coverage moved to the package's own test
  suite on develop); git-sync/test now holds engine tests only.
- .gitignore / Dockerfile / test.yml / AGENTS.md: unioned — build/ ignored for
  every package; Dockerfile COPYs both prosemirror-markdown/build (mcp+git-sync
  runtime) and git-sync/build (git-sync's runtime consumer lands on this branch);
  CI builds prosemirror-markdown before git-sync/mcp.
- pnpm-lock.yaml regenerated for the merged workspace.

Branch adaptations to canon (server-side tests only — converter untouched, per
the guardrail that converter fixes go to the package on develop, fixtures-first):
- git-sync-converter-gate.spec.ts: heading textAlign and image width/height now
  round-trip via the canon trailing-comment forms (#9 `<!--attrs {...}-->`, #4
  `<!--img {...}-->`) instead of the old HTML-tag forms — expectations flipped to
  the real canon output. RESIDUAL: canon #4 does not yet carry image `align`
  (documented as a known divergence; fix belongs in the package on develop).
- schema-attribute-contract.spec.ts: the schema mirror moved from
  `@docmost/git-sync/lib/docmost-schema` to `@docmost/prosemirror-markdown`;
  import + jest source-mapper updated.

Verified: prosemirror-markdown/git-sync/mcp build clean; git-sync corpus green;
server `tsc --noEmit` 0; gate + schema-attribute-contract specs 32/32.

test(git-sync): correct the image align gate note — align round-trips, no residual 4f64fae0fe

Earlier this gate framed image `align` as a 'residual gap' (align dropped, fix
owed in develop). That was a false diagnosis. align round-trips correctly:
`center` is the schema default (emitter omits it, importer restores it), and the
`toBeUndefined()` here reads the CANONICAL form where canonicalize normalizes the
`center` default away symmetrically — not a loss. The real round-trip instability
in this family was the empty-string-vs-absent class (image.alt `absent -> ""`),
fixed parse-side in the converter package on develop (PR #350); this branch
absorbs it via the next develop merge. Comment/title only — assertions unchanged.

Merge branch 'develop' of https://gitea.vvzvlad.xyz/vvzvlad/gitmost into wt119-git-sync 8893069500

fix(git-sync): resolve develop-merge artifacts F1 (lockfile) + F2 (stale mcp schema test) a2e63e7ea3

Domerge of current develop (with #341/#349) into feat/git-sync left two CI blockers:

- F1: `pnpm-lock.yaml` — the auto-merge dropped `@docmost/git-sync` from the
  `apps/server` importer (present in apps/server/package.json), so
  `pnpm install --frozen-lockfile` failed (CI + Docker red at install).
  Regenerated with `pnpm install --lockfile-only --fix-lockfile`; faithful frozen
  install now EXIT 0.
- F2: removed `packages/mcp/test/unit/schema-surface.test.mjs` — a branch-only
  ORPHAN. develop deleted it when mcp moved onto `@docmost/prosemirror-markdown`
  (mcp's docmost-schema.ts now RE-EXPORTS the package schema); its inline
  reference was stale (missing the package's image `caption`). Coverage lives in
  `packages/prosemirror-markdown/test/schema-surface-snapshot.test.ts` on develop.
  mcp node --test now 480/480.

Verified (merged head): frozen install 0, editor-ext/pm-markdown/git-sync/mcp
build 0, server tsc 0, mcp 480/480, gate + schema-attribute-contract 32/32.

fix(lock): commit the regenerated pnpm-lock.yaml (#119 F1 recurrence) e46e89b58c

The prior F1 fix regenerated the lock in the working tree but a multi-pathspec
`git add` (that also named an already-`git rm`'d file) aborted before staging
pnpm-lock.yaml, so only the F2 deletion landed in a2e63e7e — the pushed lock was
still missing `@docmost/git-sync` in the apps/server importer and CI/Docker were
red at `pnpm install --frozen-lockfile`. Root cause (per reviewer): develop's
apps/server does NOT depend on git-sync (it lives only on this branch), so every
develop merge auto-resolves the lock's apps/server importer to the develop
version and silently drops git-sync — the lock must be regenerated and committed
AFTER each merge. This commits the regenerated lock (git-sync back in the
apps/server importer).

Merge-verify: голова = одобренный round-14 #119 (e46e89b5) ⊕ свежий merge develop (5336f06d, поглощает #350). Сверил, что одобренный контент сохранён и develop вобран чисто.

Сверено (по коду):

Нет дрейфа конвертера: packages/prosemirror-markdown/src == develop (пустой дифф) — #350 (стабилизация «пустая строка ≡ отсутствие») вобран корректно.

Объективка зелёная (мой прогон, CI-условия, чистое дерево, реальные сборки): frozen install 0; сборка editor-ext/prosemirror-markdown/git-sync/mcp 0; пакетные тесты — prosemirror-markdown 682 (вкл. #350), git-sync 268, mcp node --test 480/0; server tsc 0; адаптированные git-sync-спеки (converter-gate + schema-attribute-contract) 32/32.

🐛 BUG (engine → this PR) — silent data loss: a freshly git-added `.md` with an unknown `gitmost_id` is DELETED from the vault + remote

Route: engine — @docmost/git-sync push classifier / reconcile (not the converter package).
Severity: HIGH (silent loss of user-authored git content; no failure, no wedge).
Confidence: high, deterministic ≥2× (valid-but-nonexistent UUID, and a non-UUID token).

Repro (RU)

В git-репозиторий git-sync-пространства закоммитить новый файл WT-ghost.md с фронтматтером gitmost_id: 019f2500-dead-7000-8000-000000000009 (корректный по формату UUID, но НЕ соответствует ни одной странице; либо не-UUID токен [unclosed) и телом.
git push origin HEAD:main. Подождать ~2 цикла (~16с).
git fetch — файл исчез: движок его удалил и запушил удаление.

Expected

Файл с неизвестным/несуществующим gitmost_id — это НЕ страница, удалённая в Docmost (её никогда не было). Его нельзя молча удалять. Ожидается: пропустить (skip + лог) или адоптировать как новую страницу — контент git-автора сохраняется.

Actual

push plan counts: 0 create, 0 update, 1 delete, 0 rename/move, 0 skipped
  delete: 019f2500-dead-7000-8000-000000000009
push complete: ... 1 deleted, 0 failure(s)

Импорт корректно скипается (guard «no page with that id» — регрессия #119 НЕ произошла, спейс не виснет ✅). Но push-классификатор видит файл с id, которого нет среди live-страниц Docmost, и классифицирует его как delete → удаляет файл из vault и пушит удаление в remote. Контент потерян молча.

Root cause

Push absence-delete не различает: (a) файл, id которого БЫЛ в refs/docmost/last-pushed (реально синхронизированная страница, удалённая в Docmost → удалять корректно) vs (b) СВЕЖЕ добавленный файл с мусорным/чужим id, которого в last-pushed никогда не было (→ удалять нельзя, это ADD). Классификатор удаляет по факту «id есть в vault, нет в live», без проверки, что id ранее синхронизировался.

Suggested fix

Absence-delete должен срабатывать только для id, присутствовавшего в last-pushed (ранее синхронизированного). Файл, чей id впервые появляется в рабочем дереве (нет в last-pushed) и не матчит live-страницу → skip/adopt, не delete. (Это добивает 4-й вариант id-класса из хвостов #119, но со стороны own id и с симптомом «тихое удаление файла», а не wedge.)

Найдено полным веб-прогоном (charter P3). Проверено детерминированно на чистом сиде.

🐛 BUGS (converter → `@docmost/prosemirror-markdown`, fixtures-first) — round-trip fidelity gaps found in the canonical converter

Route per guardrail #2: these are in the shared converter package (md↔pm), not the branch. Found via full web-test (charter P6), each verified deterministically by calling the built converter directly (markdownToProseMirror/convertProseMirrorToMarkdown).

P6-B [MED] — inline HTML comment in running prose is SWALLOWED (content deleted, adjacent text joined)

markdownToProseMirror('pre<!--SECRET-->post')  →  paragraph text "prepost"   (comment gone)
'a<!--x-->b<!--y-->c'  →  "abc"

The converter uses HTML comments as canonical data carriers (, , ), so a literal comment is silently erased and the tokens on either side are merged with no boundary. For a vault whose value prop is lossless round-trip, a literal comment should survive (or at least not merge adjacent content). Deterministic 3×.

P6-A [MED] — Obsidian titled callout `> [!info] Title` drops the title on import

'> [!info] This Is A Title\n> body'  →  callout(type:info) with body "body"; "This Is A Title" GONE

> [!type] title is valid Obsidian syntax; the title text is silently lost (Docmost's callout node has no title slot, canonical emit is bare > [!info]). Since the feature advertises Obsidian-native callouts, dropping the title is data loss for an Obsidian author. Suggest folding the title into the callout body (e.g. a leading bold paragraph) rather than discarding. Systematic, 6+×.

P6-H [LOW] — highlight `==a == b==` mis-tokenized, non-round-trip

'==a == b=='  →  re-exports as '==a ==b\=\='   (content changed)

==x = y = z== (equals not adjacent to ==) is fine. Ambiguous adjacent-== authoring, but it changes content on round trip. LOW. 2×.

P6-img [LOW / likely unsupported] — standalone `` block (no `![]()` prefix) dropped entirely

The engine only ever emits  as a suffix to an ![]() image, so a bare hand-authored  isn't a produced canon form. Reporting for completeness; probably wontfix.

Not bugs (disconfirmed, for the record): code-block literal markers stay literal ✅; in-body >[!warning]-looking text does NOT false-trigger a callout ✅; unicode/emoji/CJK/RTL/8k-line intact ✅; the converter is a fixpoint on its own canonical output (idempotent, churn=0) for every construct ✅ — these gaps are all first-pass PARSE loss on hand-authored input, not oscillation.

I'll mirror local fixtures-first fixes for the clear ones (P6-B, P6-A) in my working copy to keep the test loop converging; final fix belongs in a package PR on develop per the routing rule.

D-P3-1 follow-up — fix analysis (I explored two local fixes; BOTH have edge cases → the correct fix needs a page-existence check)

I tried to fix this locally (my working copy only, not pushed) and want to save the maintainer time by documenting what does and doesn't work. The root is the pull's absence-reconcile (planReconciliation in engine/reconcile.ts): a tracked file whose pageId is absent from live is deleted. "Absent from live" has FOUR causes — only one should be preserved:

cause	correct action
page deleted → Trash (soft-delete)	delete the vault file ✅
page hard/permanently deleted	delete the file (or leave orphan)
page moved to another space	delete the source file ✅
ghost: file with an id that was NEVER a page	KEEP (this is D-P3-1)

Attempt 1 — gate on "id was in refs/docmost/last-pushed" (previously synced): genuine deletes work, ghost survives ONE cycle — but once the ghost file is committed to the vault it enters last-pushed, so the next cycle sees it as "previously synced" and deletes it. ❌ (ghost-pollution)

Attempt 2 — gate on "id is in Trash" (listTrash): ghost never enters Trash, so it's correctly preserved forever; genuine trash-deletes work. BUT a cross-space move leaves the moved page live in space B (not in A's Trash) → A's source file is no longer absence-deleted → orphan .md in A. ❌ (move-cleanup regression, same class as the known orphan-on-empty tail)

Conclusion — the correct signal is "does this pageId correspond to ANY real page row (any space, any state)?": ghost → no row → keep; deleted/moved/trashed → row exists → delete the source file. This needs a bulk existence check (e.g. a new client method pageIdsExist(ids) → Set = SELECT id FROM pages WHERE id = ANY($ids) incl. deleted, any space), gating only the small candidate-delete set. That's a clean but non-trivial change in the data-loss-critical reconcile path, in the same id-class family as the already-tracked open tails — so I'm leaving it to the maintainer rather than shipping a half-correct guard. Both of my attempts are reverted; the bug report above stands. Happy to implement pageIdsExist + the gate if you want it.
