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

Upgrades the 2-way body merge to a real diff3 three-way merge (review #5), so a
block ONLY the human changed is KEPT when git changed a DIFFERENT block — the
2-way merge would revert it to git's stale version.
Engine: the push update loop reads the last-synced pre-image
(`git.showFileAtRef(refs/docmost/last-pushed, path)`) and passes it as the
optional `baseMarkdown` to `client.importPageMarkdown` (the common ancestor).
Server: gitmost-datasource converts base+incoming, and writeBody runs a block-
level diff3 (new three-way-merge.ts `diff3Plan`): live-only change -> keep live,
git-only change -> take git, both-changed -> git wins (conflict policy), inserts/
deletes from either side preserved. Without a base (createPage) it falls back to
the 2-way merge. Crash-safety unchanged (docs built before the connection opens).
Tests: three-way-merge.spec.ts (14 — every diff3 case incl. the cross-block
preservation and conflict policy), yjs-body-merge 3-way (real Y.Docs: human's
block instance preserved while git's block is applied), plus an engine test that
the base is forwarded from showFileAtRef. Existing push assertions updated for the
new base arg. git-sync 589 pass; server merge/datasource/gate 62 pass; typecheck
clean.

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).

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 ) 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.
