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).

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.

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.

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.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.

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

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

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

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

Self-review of phase 3 caught a data-corruption regression: nativeMeta always
supplies the run's spaceId, so the planner's 'create-without-spaceId' skip — which
had doubled as the only filter for non-page files — went dead. An ADDED
.obsidian/*.json, attachment, or dotfile (committed to the vault, no .gitignore)
would then be classified as a CREATE: a junk Docmost page, plus a gitmost_id
frontmatter written INTO the file, corrupting it.
Fix: isPageFile(path) — a .md file with NO dot-segment anywhere — and filter the
diff to page files at the very top of computePushActions, BEFORE any
classification, so non-page A/M/D/R are ignored (design §Адопция). 2 unit tests
pin it (.obsidian/json, attachment, dotfile, dot-segment, .md dotfile all ignored;
real pages still created). 614 engine tests green.
Also: refreshed stale docmost:meta comments to gitmost_id (review SUGGESTION), and
documented the deferred adoption frontmatter-preservation gap (review WARNING) in
page-file.ts + the design doc (do NOT roll native onto a real vault with Obsidian
properties until phase 4 round-trips them).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
PUSH now consumes the native-Obsidian format end-to-end:
- identity from the gitmost_id frontmatter (parsePageFile), not docmost:meta;
- title from the FILENAME, parentPageId from the enclosing folder's folder-note
(parentFolderFile is now FOLDER-NOTE aware: a child's parent is dir/dir.md, and
a folder-note's own parent is one level up), spaceId from the run (every vault
file belongs to the vault's space);
- CREATE derives title/parent/space from path + run and writes the assigned
pageId back as gitmost_id frontmatter (serializePageFile);
- UPDATE pushes the STRIPPED body (current + 3-way-merge base), so the frontmatter
never leaks into Docmost content; the loop-guard hashes the body.
The PURE delete-sensitive classifier (computePushActions/classifyRenameMoves) is
UNCHANGED — only the injected IO resolvers (metaAt, parent, create write-back)
switched source. nativeMeta always carries the run spaceId, so the legacy
'create-without-spaceId' skip no longer fires through runPush.
Tests rewritten to native fixtures + folder-note parent paths; the noop case is
now a child under a renamed parent folder (filename=title, so a path-only-noop
needs an ancestor rename). parentFolderFile tests cover leaf/folder-note/nested/
dotted. 612 engine tests green; engine rebuilt.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.

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.

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).
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 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.

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.

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).

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.
