agent_coder	c1b2210a4e	fix(#370 ): thread trx into addPageWatchers (F7 self-deadlock) + restore contributors on commit-failure (F8) + assert the lock (F9) (review round 2) The round-1 F3 fix (wrapping the processor's find+save in a locked tx) itself introduced two regressions: F7 [CRITICAL] addPageWatchers ran WITHOUT trx inside the tx holding FOR UPDATE on pages[pageId]. The watcher insert's FK check takes FOR KEY SHARE on the same row, but on a DIFFERENT pool connection — a true self-deadlock (our tx connection sits idle-in-transaction awaiting the JS await, the insert connection blocks on the lock). Now passes trx (addPageWatchers already accepts it and routes it through insertMany), so the FK lock is taken on the connection that already holds FOR UPDATE — no self-conflict. F8 [WARNING] popContributors is a destructive Redis SPOP; the inner catch only restores on a throw INSIDE the callback. A COMMIT failure throws OUTSIDE it, rolling the snapshot back while the pop is gone → a retry writes an unattributed version. Now tracks the popped set and restores it in an outer catch (idempotent SADD), leaving BullMQ to retry with attribution intact. F9 [WARNING] The spec asserted saveHistory args with a loosened objectContaining that stopped verifying trx, and never pinned withLock/trx on findById or the trx on addPageWatchers — which is exactly why F7 slipped. Restored the exact saveHistory(trx) assertion and added findById({withLock,trx}) + addPageWatchers trx assertions (the latter would have caught F7), plus a commit-failure test.

fix(#370 ): thread trx into addPageWatchers (F7 self-deadlock) + restore contributors on commit-failure (F8) + assert the lock (F9) (review round 2)

The round-1 F3 fix (wrapping the processor's find+save in a locked tx) itself
introduced two regressions:

F7 [CRITICAL] addPageWatchers ran WITHOUT trx inside the tx holding FOR UPDATE on
pages[pageId]. The watcher insert's FK check takes FOR KEY SHARE on the same row,
but on a DIFFERENT pool connection — a true self-deadlock (our tx connection sits
idle-in-transaction awaiting the JS await, the insert connection blocks on the
lock). Now passes trx (addPageWatchers already accepts it and routes it through
insertMany), so the FK lock is taken on the connection that already holds FOR
UPDATE — no self-conflict.

F8 [WARNING] popContributors is a destructive Redis SPOP; the inner catch only
restores on a throw INSIDE the callback. A COMMIT failure throws OUTSIDE it,
rolling the snapshot back while the pop is gone → a retry writes an unattributed
version. Now tracks the popped set and restores it in an outer catch (idempotent
SADD), leaving BullMQ to retry with attribution intact.

F9 [WARNING] The spec asserted saveHistory args with a loosened objectContaining
that stopped verifying trx, and never pinned withLock/trx on findById or the trx
on addPageWatchers — which is exactly why F7 slipped. Restored the exact
saveHistory(trx) assertion and added findById({withLock,trx}) + addPageWatchers
trx assertions (the latter would have caught F7), plus a commit-failure test.

fix(#370 ): ES2021-safe spec, source-specific idle ceiling, processor lock, tested index mapping (review round 1)

F1 [BLOCKER] persistence-store.spec used Array.prototype.at(-1) (ES2022) but the
server targets ES2021, so server tsc failed (TS2550) and ts-jest could not
compile the suite — 22 core manual-save/idle/boundary tests silently did not run
in CI. Replaced with [length - 1] index access.

F2 [WARNING] The idle burst-reset used a hardcoded IDLE_MAX_WAIT_USER for both
tiers, but computeHistoryJob's ceiling is source-specific. On a continuously
agent-edited page the burst marker stayed stale for 5..10m, forcing delay=0 on
every store and writing one idle row per store — the exact per-store bloat the
debounce prevents. The reset now uses the same source-specific max-wait.

F3 [WARNING] The processor did an unlocked findPageLastHistory -> saveHistory,
which TOCTOU-races a concurrent manual-save (that runs under a page-row lock),
producing two page_history rows with identical content (one idle, one manual) and
defeating promote-not-dup. The snapshot decision is now wrapped in executeTx with
the same page-row lock, so the second writer observes the first's committed row
and the isDeepStrictEqual gate collapses the duplicate.

F4 [WARNING] The risky client filtered-index -> full-list mapping had no tests.
Extracted it to a pure resolvePrevSnapshotId(fullItems, id) helper (diff/restore
baseline against the true previous snapshot in the FULL list, never the previous
visible version) and unit-tested it; removed the now-vestigial index threading.

F5/F6 [low] Renamed the misleading ceiling test + fixed its comment; added a
CHANGELOG entry for the user-facing versioning feature.

feat(#370 ): page-history intentionality tiers — kind column + intentional/idle/boundary triggers (PR-1 core)

PR-1 'core' of #370: introduces page_history.kind ('manual'|'agent'|'idle'|
'boundary'; legacy null = autosave) and rebuilds the snapshot triggers around a
three-tier intentionality model. Draft durability (pages/ydoc hocuspocus
autosave) is unchanged; only the frequency and labelling of history points change.

- Migration 20260705T120000: page_history.kind nullable varchar(20), no default.
- Manual Save: one stateless 'save-version' path for human AND agent; kind is
  derived SERVER-SIDE from the signed context.actor (never the payload), readOnly
  connections rejected, the fresh ydoc runs through the existing store path (no
  REST race), then broadcasts version.saved.
- Idle-flush: trailing debounce (one BullMQ job per page, remove-then-readd) with
  IDLE_INTERVAL_USER=60m / AGENT=15m AND a max-wait ceiling
  (IDLE_MAX_WAIT_USER=10m / AGENT=5m) so a continuous editing session can't starve
  the autosnapshot (review round-1 WARNING).
- Boundary: generalized from the user→agent special-case to ANY lastUpdatedSource
  transition (user↔agent↔git), same isDeepStrictEqual gate — covers git-sync free.
- Removed the agent delay=0 fast path and the old HISTORY_FAST_* constants; the
  agent joins the common idle pipeline.
- Promote-not-dup: a manual save on unchanged content promotes the latest
  autosave's kind in place (or no-ops if already manual) instead of duplicating a
  heavy content row.
- Client: mod+S hotkey + menu button (hidden when readOnly), history-panel kind
  badges, dimmed autosaves, a 'versions only' filter (indices map to the full
  list so diff/restore still target the true previous snapshot), live refresh on
  version.saved.

Internal review: APPROVE-with-suggestions; the round-1 WARNING (idle starvation)
is fixed here via the max-wait ceiling, and the generalized-boundary + ceiling
behaviours are pinned with new tests (115 collab/repo specs green, server tsc 0).

Deferred to later PRs: shares.published_mode (PR-2), the save_page_version MCP
tool + role prompts (PR-3), actor='git' wiring into #359 (PR-4).
