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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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

build/ is gitignored and compiled in CI/Docker; a few files leaked back into
the tree while replaying commits onto develop. Remove them so the package keeps
a single source of truth (src/).
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.

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.

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).

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.

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".

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).

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.

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.

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.

Per owner: test data, no migration. parsePageFile no longer reads the old
docmost:meta block — a file without a gitmost_id frontmatter is simply un-tracked
(adopt). Vaults are a cache: rm -rf on the transition, rebuilt native from
Docmost. Simplifies the format work (no fallback). Doc updated.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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
rewritten to the native-Obsidian format.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Pure read/write/lookup for the vault sidecar index that will hold page identity
(pageId) + collision token (slugId) keyed by file path, so the .md files can be
clean markdown. parseVaultIndex is tolerant (missing/garbage/bad entries degrade
to empty/skipped — never crashes a cycle); serializeVaultIndex is deterministic
(sorted keys -> stable diffs, no churn). Lookups (pageIdAt, pathForPageId reverse,
trackedPageIds) + mutations (set/remove/move). NOT wired into pull/push yet — no
behavior change. 5 unit tests; engine suite green.

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.

The shell e2e suites defaulted to the General space and created/edited pages
there, polluting real content (and, when several enabled spaces raised poll
contention, flaking on 503s). Now each suite creates its OWN throwaway,
git-sync-enabled space at setup, runs everything against it, and deletes the
space (+ its vault) on exit. Set SPACE_ID explicitly to opt into an existing
space. Also gives the basic suite the 503-retry push helper the advanced one
already had. Verified isolated: basic 12/12, advanced 23/23, no spaces/users/
pages left behind, the real space untouched.

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).

Reproduces the browser bug at the API level: create several untitled pages (all
collapse to the `_` fallback name), retitle one, sync — assert NO page is
trashed and all survive. Caught the data-loss bug fixed in 4376c5a6.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
CRITICAL data-loss bug: creating pages in Docmost (which start UNTITLED) and then
typing a title could soft-delete OTHER pages. Untitled pages all serialize to the
`_` fallback filename; the layout disambiguates them (`_.md`, `_ ~slug.md`).
Retitling one frees the bare `_` and another untitled page's file relocates into
it. git's rename detection (`-M`) can't see the move (the tiny meta-only files are
too dissimilar), so `git diff` reports it as DELETE(old) + ADD/MODIFY(new). The
push took the DELETE literally and trashed a live page.
Root cause is that the push trusted git's path-level rename heuristic for page
IDENTITY. Identity is the pageId. Fix: before emitting any delete, coalesce by
pageId — a pageId that is BOTH deleted (pre-image) AND present on the surviving
side (current meta of an ADD or a MODIFY, since a relocation into an occupied path
shows as M) is one page that MOVED, classified as a rename/move and NEVER a delete.
Reproduced + verified on a live stand: 4 untitled pages + retitle one trashed a
different page before; after the fix, retitling one (and stress-retitling all)
trashes nothing. Engine suite 598 green; 3 new computePushActions cases (ghost
D+A move -> rename; real delete still deletes; unrelated D+A stay delete+update).

The 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.

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).

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.

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.

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.

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.)

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).

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

The debounce map value carried `workspaceId`, but the scheduled cycle closes over
the `workspaceId` argument directly — the field was written and never read.
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
repo's pre-existing set of jest suites that can't load locally via the
react-dom/tiptap transform chain — unaffected by this change; tsc clean.)

The two-way block diff (yjs-body-merge.diffBlocks) and the three-way merge

traceback. No behavior change — merge specs unchanged and green.

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).

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).

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.

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.

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.

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.

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.

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.)
