Card t_11f2cf60. Live: plugin fired but logged unavailable=timeout partial_cards=0 on every resumed session (750 ms budget).

Changes

  • kanban_db.home_ids: per-process TTL(300s)/LRU(256) cache keyed (sid, path, inode); fail-open answers not cached. home_lineage() also returns the home's earliest started_at.
  • plugin home_ids delegates to the shared lineage helper (was exact-id).
  • Probe (lineage -> dedupe -> boards) on a daemon thread. In the gateway it starts at pre_gateway_dispatch from the in-process store (peek_session_id, no DB); pre_llm_call waits <= BUDGET_S.
  • Board filter: skip non-root boards whose kanban.db mtime < home start - 300s with empty WAL.
  • BUDGET_S 0.75 -> 1.5. Timeout log: stage=lineage|dedupe|boards partial_cards ms prewarmed; success log: per-stage ms + mtime_skipped.

Verified

  • tests/plugins/kanban_home_cards + tests/hermes_cli/test_kanban_home_lineage.py: 84 passed (nice -n 19, load ~88).
  • Live read-only run of branch code vs ~/.hermes (fresh process, load 77-79): session 20260922_181235 cards=14 ms=333 (lineage 1, dedupe 1, boards 302); 20260921_002254 cards=0 ms=1324 (boards 1317).

Known limits

  • mtime filter skipped 0/77 boards live: both lineages start Sep 19-21 and every board's kanban.db was rewritten ~12h ago. The filter is correct but inert for long-lived homes on this host; board fan-out is now the cost.
  • Scratch-profile gateway restart proof (card DONE test(models): make anthropic-messages warning test hermetic #4) not done here.

DEQUEUED by Apollo 07:2x PT: this PR breaks main's tests/plugins/test_kanban_home_facet.py::test_viewer_home_uses_session_lineage_not_exact_id (from #1014, home-session facet) — it failed in every merge group containing #988 (r-1012 group, r-1043 group), ejecting siblings and costing ~45 min per cycle. Reconcile kanban_home_index.py lineage lookup with the facet's session-lineage expectation, push, then re-enqueue via fleet-merge.sh. Card t_11f2cf60.

…lter, stage-attributed timeout (t_11f2cf60)

- kanban_db.home_ids: per-process TTL/LRU cache (keyed sid+path+inode);
  fail-open answers not cached. New home_lineage() also returns the
  home's earliest started_at.
- plugin: home_ids now delegates to the shared lineage helper.
- plugin: probe (lineage -> dedupe -> boards) runs on a daemon thread,
  started at pre_gateway_dispatch from the in-process session store
  (peek_session_id, no DB) so it overlaps auth/agent build; pre_llm_call
  waits at most BUDGET_S.
- boards whose kanban.db predates the home start (minus 300s slack) with
  an empty WAL are not opened; root always scanned.
- BUDGET_S 0.75 -> 1.5; timeout log names stage=lineage|dedupe|boards,
  ms, prewarmed; success log carries per-stage ms and mtime_skipped.

Tests: tests/plugins/kanban_home_cards + tests/hermes_cli/test_kanban_home_lineage.py
84 passed (nice -n 19, load ~88).
… boards on the turn (t_11f2cf60 r2)

Apollo ruling on Argus r1 (B1/B2/B3): the first turn no longer opens ~78
board DBs. hermes_cli/kanban_home_index.py keeps a single cross-board
index (<kanban_home>/kanban/home_index.db: board, task_id, session_id,
status, title, last_comment, last_activity, ev) maintained from
kanban_db.write_txn after every outer COMMIT -- the one boundary guarded
mutators and execution-lane writers share. Event-driven (per-board
task_events watermark, per-row ev so older snapshots never win), best
effort, never fails a board write. `hermes kanban home-index` backfills;
`--check` reports drift (exit 1) for the daily cron.

Plugin: lineage (cached home_ids) -> state.db dedupe -> ONE indexed read.
Missing/unbackfilled/unreadable index renders nothing with one log line;
boards are never scanned. Removed the mtime filter, pre_gateway_dispatch
prewarm and _BudgetExceeded. Budget back to 750 ms. Every first turn logs
one line incl. dedupe (history|state.db) and per-stage ms.

Verified: tests/plugins/kanban_home_cards + test_kanban_home_lineage +
test_kanban_home_index: 89 passed. Live read-only (scratch index built
from the 77 live boards, load 79-80, no head start): 8/8 sessions match
an independent raw-sqlite oracle, hook 18-130 ms.
Apollo and others added 2 commits September 25, 2026 07:31
…onverge event-less writers (t_11f2cf60 r3)

B1: lineage + dedupe run on background threads with STATE_WAIT_S=0.35;
past that the home is id + in-process parent_session_id + the lineage
persisted in the home index (homes table, written off the turn path after
home_ids resolves). Subset of truth: may under-count, never foreign.
Dedupe not answered in time -> inject. Log names lineage=state.db|index|
in-process and dedupe=clean|pending.

B2: sync_after_commit fingerprints the board's stamped (id, session_id,
status, title) set on every commit and diffs it against the index, so
delete_task / delete_archived_task (events deleted), transfer scrub,
swarm, and raw dashboard UPDATEs converge at their commit or the next
write_txn commit on that board. Test per path.

Verified: focused suite 99 passed; the 5 new sweep tests fail on r2's
index code; live read-only probe 4/4 vs oracle, cold-lineage session
rendered in 360 ms via in-process fallback.
…o staged state.db gate (t_15d21849) (#1036)

- BUDGET_S 0.75 -> 0.22; STATE_WAIT_S removed. Lineage, dedupe and a
  fallback-home index read start together; the turn wakes on each
  completion and at the ceiling takes exact > fallback cards, else skips.
- Wait sliced into 2 ms: the loaded Studio oversleeps a single 0.25 s
  timed wait by ~140 ms (measured 383-397 ms); sliced 251-265 ms.
- Tests: 77-board fleet fixture (warm, cold state.db, locked index,
  27 concurrent first turns), all under the 250 ms ceiling.

Bench on a copy of the live 77 boards under load: main p50 726/p95 1293 ms
(27/27 over 250); this head p50 21/p95 214, cold state.db p95 248 ms, 0 over.

…at (t_11f2cf60)

r1 added started_at to every lineage SELECT; a schema lacking it (the
#1014 dashboard facet fixture, older state.db) raised and home_ids failed
open to the exact id, breaking test_viewer_home_uses_session_lineage_not_exact_id.
Select started_at only when the column exists; start is None otherwise.

Verified: test_kanban_home_facet + home_lineage + home_index 47 passed,
kanban_home_cards 66 passed; new regression test fails without the fix.
