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.

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).

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.

Comprehensive-review follow-ups (APPROVE WITH SUGGESTIONS; no critical issues):
- poll interval is now actually configurable: replaced the hardcoded
@Interval('git-sync-poll', 15000) with a dynamic SchedulerRegistry interval
registered in onModuleInit from getGitSyncPollIntervalMs() (cleared in
onModuleDestroy); /status and the real cadence now share one config source.
Boots logging 'poll interval registered (Nms)'.
- loop-guard now ALWAYS applies: the lastUpdatedSource==='git-sync' skip was
nested inside the !spaceId/!workspaceId branch, so structural self-writes
(CREATE/MOVE/RESTORE/SOFT_DELETE, which carry spaceId+workspaceId) bypassed it
and re-triggered cycles. Fetch the page row once, guard unconditionally, then
resolve space/workspace.
- remove the dead PAGE_CONTENT_UPDATED subscription (it's a BullMQ job, never an
EventEmitter event; body edits arrive via PAGE_UPDATED).
- fix the stale datasource comment (PageService DOES stamp 'git-sync' now).
- env getters: parseInt radix 10 + NaN/<=0 fallback for poll/debounce (+ max
deletes), with 6 new environment.service.spec tests.
tsc clean; jest 723 pass; live cycle re-verified post-refactor (ran, push
applied, unflagged 92-page space untouched).
