claude code agent 227 f3dbcec0fd refactor(git-sync): DRY the move+body emission; cover M-side ghost-move (F7,F8)
F8: extract emitMoveWithBody helper (renamesMoves + body update with
    basePath=oldPath) and call it at all three rename emission sites (ghost-move
    A, ghost-move M, R/C) — byte-identical behavior, single F4 rationale. Helper
    placed above computePushActions so the planner JSDoc stays attached.
F7: add an M-side ghost-move test (D+M same pageId) asserting the move and the
    body update carry basePath=oldPath — the previously-untested branch.

claude code agent 227 63f948df10 fix(git-sync): deliver body on rename+edit via honest 3-way merge; cover CREATE strip; fix env doc (F4-F6)
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.

claude code agent 227 b47751349f fix(git-sync): kill spurious marker-leaking conflict, concurrent-edit loss, flapping HEAD
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.

claude code agent 227 b7e5cb6970 fix(git-sync): push 503 starvation + concurrent-edit marker leak/silent loss
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.

claude code agent 227 906733b5c8 fix(git-sync): address PR #119 review #4 — symlink guard, dead-code cull, changelog + warnings/suggestions
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).

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

claude code agent 227 32e99c6e42 fix(editor,git-sync): parse details open as a boolean so open state survives render/round-trip

claude code agent 227 e48d7720e9 fix(git-sync): propagate nested details open; drop dead delete-cap wiring; cover lost-lock abort + lose-prone atom round-trips
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.

claude code agent 227 b5ce63a956 feat(git-sync): Obsidian-native callouts (> [!type]) instead of :::type
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.

claude code agent 227 abd6e3948b fix(git-sync): preserve subpages.recursive and details.open on round trip
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.

claude code agent 227 5125296bfa fix(git-sync): subpages round-trips (was {{SUBPAGES}} literal) + exhaustive all-node round-trip test
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.

claude code agent 227 a40a00d5c5 feat(git-sync): per-space toggle for conflict-marker handling on push (#13)
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.

claude code agent 227 d5079aa1d8 fix(git-sync): red-team hardening — 12 confirmed sync-breaking bugs + regression tests
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.

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

claude code agent 227 5da12e89f9 refactor(git-sync): internalize the engine — first-class ESM, no vendoring bridge (#119 review)
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).

claude code agent 227 f6d22a59a6 fix(git-sync): screen non-page files out of PUSH (CRITICAL — review)
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).

claude code agent 227 d255afa611 feat(git-sync): phase 3 — PUSH reads native gitmost_id + derives title/parent from path
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.

claude code agent 227 73c5c44301 feat(git-sync): phase 2b — PULL writes native gitmost_id frontmatter
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.

claude code agent 227 8c42c4f0d6 feat(git-sync): phase 2a — folder-note layout (parent -> Folder/Folder.md)
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.

claude code agent 227 071eae4e2a feat(git-sync): drop legacy docmost:meta back-compat (vaults wipe+rebuild)
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.

claude code agent 227 a91405632e feat(git-sync): native-Obsidian format — phase 1 = page-file (frontmatter gitmost_id)
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.

claude code agent 227 aa1ee64b7a feat(git-sync): thin-meta phase 1 — the .gitmost/index.json sidecar module
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.

claude code agent 227 40ca04eb08 fix(git-sync): never trash a page whose pageId still exists in the tree (cross-cycle move) + browser e2e
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).

claude code agent 227 c3dbee9fbf fix(git-sync): never trash a page that only MOVED (pageId-identity, not git rename heuristics) — data loss
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).

claude code agent 227 dc7a0ec9f5 refactor(git-sync): move the PULL->PUSH cycle into the engine as runCycle (PR #119 review, arch #1)
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.

claude code agent 227 fa89cba023 feat(git-sync): three-way body merge using the last-synced base (no edit loss)
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.

claude code agent 227 d06cf97ed6 test(git-sync): exhaustive converter coverage + fix 3 round-trip data-loss bugs
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).

claude code agent 227 70bd0dba4d feat(git-sync): vendor IO engine (pull/push/git/settings) with GitSyncClient seam (Phase A.3)
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).

claude code agent 227 b0cd4bd6cf feat(git-sync): CommonJS build + §13.1 editor-ext idempotency gate (Phase A.2)
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.

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.
