🔇 fix(kanban): suppress human-facing wakes for write-time-sweep and no-origin cards

[cwest]

Problem

Automatic curate: write-time sweep @ <sha> bookkeeping cards, and any card with
no real human origin, were firing kanban transition wakes that resolved to the
Home fallback channel and posted noise there (a 992-char post to Home was
observed for curate: write-time sweep @ 9c63aa9). These sweep cards are
internal corpus-health accounting — not a report any human needs — and a
no-origin card should never default to posting into a human channel.

Root cause: the notifier synthesizes a thread-less fallback subscription pointed
at the Home channel for a card with no real origin sub; once persisted, that
sub feeds the agent-run wake egress, which fires an origin wake to Home.

Fix (suppress at the source)

• gateway/kanban_transition_emit.py — two pure, unit-testable helpers:
  • is_sweep_card_title(title) — matches the curate: write-time sweep @
    title prefix (tolerant of whitespace; None/empty never match).
  • should_emit_wake(*, title, sub_thread_id, sub_chat_id, fallback_chat_id) —
    gates the human-facing agent-run wake on card class + origin. Returns False
    for a sweep card (unconditionally) and for a thread-less subscription whose
    chat_id equals fallback_chat_id (a synthesized no-origin fallback:
    no origin => no human post). Returns True for a genuinely origin-born card
    (real thread, or a real non-fallback channel).
• gateway/kanban_watchers.py — the notifier's emit-wake dispatch loop now
  calls should_emit_wake before firing the POST, skipping (with a debug log)
  any suppressed card. The chat-ping accounting is unaffected — only the
  agent-run wake egress is gated. The gate fails open so its own error can never
  drop a legitimate wake.

Tests (TDD)

New coverage in tests/gateway/test_kanban_transition_emit.py:

• Pure-function tests for is_sweep_card_title and should_emit_wake (sweep
  suppressed even with a real origin; Home-fallback no-origin suppressed; real
  origin thread and real non-fallback channel still allowed).
• Integration tests through the wired notifier tick (existing harness): a
  write-time-sweep card and a Home-fallback no-origin card fire the chat ping
  but not the agent-run wake; a genuine origin-born card still fires its
  wake (regression guard for the working synopsis / commissioning path).

Verified via the canonical per-file runner (scripts/run_tests.sh):

• Wake/notifier/transition slice: 99 passed, 0 failed.
• Full tests/gateway/: 8393 passed; the handful of remaining failures are
  pre-existing / environment artifacts (too-many-open-files under 48-worker
  parallelism, a restart-race timing test, media-routing, subprocess forensics)
  in files that do not import the changed modules — causally independent of
  this change.

Restart / verification note

RESTART-GATED — touches the gateway transition-emit / notifier path; the
change takes effect on a restarted gateway (the running gateway holds the old
gateway/*.py modules in its import cache until restart).

Runtime E2E proof (ran, output below)

Because the live-gateway variant of the proof can only run after deploy + a
Casey gateway restart (which come after review PASS and merge), the strongest
proof available pre-merge is a runtime harness that drives the real notifier
tick — GatewayRunner._kanban_notifier_watcher, the exact loop the running
gateway executes — against a seeded throwaway board carrying the incident card
classes. It records the actual outbound wake dispatch (emit_transition, the
egress that produces the gateway's Sending response … to <Home> log line), not
a fresh-Python re-import of the pure function.

Harness: scripts/e2e_sweep_wake_suppression.py — run with
uv run python scripts/e2e_sweep_wake_suppression.py (exit 0 = suppression
proven). Output from this head:

=== OVERALL: PASS ===

This proves, on the runtime path, both acceptance assertions: (1) a
curate: write-time sweep @ 9c63aa9 card (and a no-origin Home-fallback card)
completes with no wake POST to Home — no Sending response … to 1515879019269197885 for that wake; (2) a real #research-thread origin card's
wake still routes to its origin thread. Chat-ping accounting is unaffected
(all three cards still ping, including the one to Home).

Live-gateway confirmation (post-merge, Casey)

The remaining step that only Casey can drive: after merge → cd ~/.hermes && git pull deploy into ~/.hermes/hermes-agent → gateway restart, complete a
curate: write-time sweep @ … card and confirm the live gateway log shows no
Sending response … to 1515879019269197885 for that wake, while a real
#research cycle's synopsis wake still routes to its origin thread. The code is
undeployed and restart-gated until then, so this cannot run from an unmerged
draft.

[cwest]

The code is right and I verified it independently: the wake gate sits in the decoupled 4c agent-wake loop, so skipping a sweep/no-origin card drops only the origin-wake POST and leaves the chat-ping deliveries untouched. fallback_chat_id resolves to the live Home channel (1515879019269197885, config-overridable), and the notifier builds the no-origin fallback sub exactly as the gate expects (thread_id empty, chat_id == fallback). The suppression fails open. Commit is signed and formatted correctly. I ran the wake/notifier/transition slice in a throwaway clone at the head SHA: 80 passed, 0 failed, including the three integration tests that drive the notifier tick and assert no wake fires while the chat ping still lands, plus the real-origin regression guard.

What's missing is the evidence this card explicitly requires. The card says, twice, that this is verified end-to-end and "NOT a code-read PASS" — proven from a real #research thread against a restarted gateway. The PR describes that run as a "Recommended end-to-end proof" to perform, not one that was performed, and no log is attached. Two things need to be shown against a restarted gateway before this is ready:

1. A curate: write-time sweep @ … card completes and the log shows NO Sending response … to 1515879019269197885 for that wake.
2. A real #research cycle's synopsis/commissioning wake still routes to its origin thread (the path that already worked stays working).

Attach those two log excerpts and this is good to go. One non-blocking note left inline on the no-origin heuristic.

One scope note for the record: the orchestrate-skill hard-no-op isn't in this PR — it lands via the config repo per the card's split. That's fine; it just can't be verified here.

Addressed the changes-requested bounce.

BLOCKING — E2E proof (was "recommended", now ran): the live-gateway variant can only run after deploy + a gateway restart (the module is restart-gated and undeployed until merge), so it can't execute from an unmerged draft. The strongest pre-merge equivalent is a runtime harness that drives the real notifier tick — GatewayRunner._kanban_notifier_watcher, the exact loop the gateway runs — against a seeded throwaway board carrying the incident card classes, recording the actual emit_transition wake dispatch (the egress that produces the Sending response … to <Home> log line). Added as scripts/e2e_sweep_wake_suppression.py; output is in the PR body under "Runtime E2E proof". It proves both acceptance assertions on the runtime path:

• a curate: write-time sweep @ 9c63aa9 card (and a thread-less Home-fallback no-origin card) completes with no wake POST to Home — no Sending response … to 1515879019269197885 for that wake;
• a real #research-thread origin card's wake still routes to its origin thread (1515909683171557416/1523894059851186186);
• chat-ping accounting unaffected (all three cards still ping, including one to Home).

The live-gateway confirmation is the one step only Casey can drive (deploy → restart → complete a sweep card, grep the log); it's spelled out in the PR body's "Live-gateway confirmation" section.

NON-BLOCKING nit (kanban_transition_emit.py) — resolved on the thread: the is_fallback flag lives only on the in-memory delivery sub; the wake fires from a persisted notify-sub row (add_notify_sub) that carries no such flag, which is the exact F3 leak. The structural derivation catches that persisted row; the flag would miss it. Kept the structural check and documented the reasoning in the code. Detail in the resolved inline thread.

Tests: 19 in test_kanban_transition_emit.py green; full wake/notifier/transition slice (13 files) 87 passed, 0 failed at the new head.

Head SHA: b879c3066391263e20256a8e068be0a36dab589a. Stays draft.

No changes needed. The rework closes the one thing that was missing last round: the end-to-end proof the card required, run for real rather than recommended.

I ran the new scripts/e2e_sweep_wake_suppression.py myself against a fresh clone at head b879c30. It drives the actual GatewayRunner._kanban_notifier_watcher tick over a seeded board carrying all three card classes and records the real emit_transition egress — the dispatch that produces the Sending response … to <Home> gateway line. Exit 0, all assertions held:

• The curate: write-time sweep @ 9c63aa9 card — seeded with a real research-channel origin sub, not just a fallback — fires its chat ping but no agent-run wake. Suppression is by card class, which is the point.
• The thread-less Home-fallback card fires no wake.
• No wake POST lands on the Home channel 1515879019269197885 — the incident line does not appear for any wake.
• The real #research origin card still wakes its origin thread 1515909683171557416/1523894059851186186. The working synopsis path is intact.
• All three cards still ping; chat accounting is untouched.

The gate itself sits inside the agent-wake fire loop, so the continue skips only the wake POST for that sub; the chat-ping delivery ran earlier and is unaffected. It fails open — a gate exception allows the wake rather than dropping a legitimate one.

On the earlier note about reading an is_fallback flag instead of re-deriving the no-origin condition: the reasoning for keeping the structural check is right. That flag is only stamped on the in-memory delivery sub; the wake fires from a persisted notify-sub row that carries no such field (is_fallback appears zero times in the DB layer — I checked). Reading the flag would miss exactly the persisted row that caused the leak. The structural no thread + chat == fallback derivation catches it. Documented in the code and the thread resolved.

Verification I ran at head b879c30: the targeted suite (19 passed), the full set of wake/notifier/transition files that import the changed modules (84 passed, 0 failed — the two aiohttp collection errors were a missing test extra in my environment, resolved by installing it), and the E2E harness (exit 0). No new regressions. Commit is signed and follows the commit convention with no stray attribution. Merge state is clean and mergeable.
