An endpoint's eventTypes allowlist matches on a name alone. A listener matches on the facts inside the payload — repo, kind, author, branch, channel — so one endpoint can carry a narrow subscription. A payload that does not normalize is ignored rather than run: too loose means waking a bot at 3am for somebody else's pull request. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The dispatch policy moves to WakeQueue unchanged — hold a busy bot's wake, serialize a room member's on the group queue, re-check busy inside that continuation, drop a wake whose bot/thread pairing is gone, and treat 'already working' as a race to retry rather than a failure to report. No connector test was edited; equivalence is the acceptance bar. drainConnectorResumes() stays a named function because main calls it from five places and the name says more at those call sites than wakes.drain(). WakeQueue takes its runtime as an explicit field rather than a constructor parameter property: the server runs under --experimental-strip-types, which strips the annotation without synthesizing the field.

Use the cardContinuation option name.
startTurn accepts cardContinuation, not connectorContinuation. The documented name will not typecheck if a future implementation follows this plan.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Pass wake.onFailure to the group continuation.
At Line 2280, runGroupMemberTurn receives no onDispatchError callback. It handles missing models and adapter dispatch failures internally, so Line 2284 does not catch them. The connector cards remain marked resumed: true without an error, and maybeResumeConnectors will not retry them.
Proposed fix
- await runGroupMemberTurn(current.group.id, wake.botId, 0, new Set(), wake.prompt);
+ await runGroupMemberTurn(current.group.id, wake.botId, 0, new Set(), wake.prompt, wake.onFailure);📝 Committable suggestion

Restrict message listeners to message events.
A Slack app_mention normalizes as kind: "mention", but a match.kind === "message" listener returns true for it. This wakes bots for mentions when the listener subscribes only to channel messages.
Return event.kind === "message" in this branch. Add a negative mention test for a message listener.

Allow updates to remove an existing listener.
A JSON update cannot send undefined. If listener is omitted, patch.listener ?? trigger.listener keeps the existing listener. The API therefore cannot remove listener filtering, and the later delete trigger.listener branch is unreachable for normal updates.
Accept an explicit removal value and distinguish an omitted field from a supplied removal value. Add an update test that clears a listener.

Use the sanitized listener context in the queued prompt.
The matched normalized event is discarded. eventPrompt still inserts raw event.payload, so a payload containing [/UNTRUSTED WEBHOOK EVENT DATA] can close the prompt boundary early. This bypasses buildEventContextBlock, including its marker stripping and field bounds.
Pass the matched NormalizedEvent to eventPrompt and use buildEventContextBlock for listener deliveries. Add an ingress test with a boundary marker in a pull-request title.

In plain language
A webhook used to be all-or-nothing. Point GitHub at a bot and every
event woke it — every PR on every repo, every comment, every push. That is not
a feature anyone would leave switched on, so in practice nobody did.
Now a webhook can carry a listener: "only a PR opened on this repo", "only
when CI fails on main", "only messages in this Slack channel containing this
word". Everything else is answered
202 ignored, with the reason recorded inthe delivery list, and no bot wakes. That is the difference between a feature
you would actually enable and one you would not.
The other half of this PR is plumbing you will not see. The harness has always
had exactly one way to wake a bot that had already finished — after you
complete a connection card — and it was hardwired to that one situation. It is
now a general queue, so the listener work above (and background executors
later) produce wakes instead of each re-implementing turn dispatch.
Connector resume must behave exactly as it did. That is the thing to look
at in review, and no connector test was edited to make it pass.
What changed
server/wakes.ts(new)WakeQueue— the dispatch policy lifted out ofdispatchConnectorResumeverbatim: hold a busy bot's wake rather than racing it, serialize a room member's on the group queue and re-check busy inside that continuation, drop a wake whose bot/thread pairing is gone, and treatalready workingas a race to retry rather than a failure to report. The runtime (startTurn,runGroupMemberTurn,groupQueues) is injected, the wayApprovalBusandCommsBusalready are.server/index.tspendingConnectorResumes/dispatchConnectorResumedeleted;maybeResumeConnectorsis now a wake producer.drainConnectorResumes()is kept as a named one-liner because main calls it from five places and the name reads better at those call sites thanwakes.drain().server/triggers.ts(new)normalizeWebhookEventturns a delivery into a flat event — GitHub (12 kinds across PRs, reviews, issues, pushes, CI) and Slack (message / mention).listenerMatchesdecides subscription.buildEventContextBlockwraps it in an untrusted boundary.server/webhooks.tsWebhookTriggergains an optional zod-validatedlistener, checked right after the existingeventTypesgate. A non-match is recorded asignoredwith a human-readable reason.Design notes worth a reviewer's eye
Being too loose is worse than being too tight. A payload that does not
normalize matches nothing, rather than falling through to a catch-all. A
GitHub
(event, action)pair with no mapped kind yieldsnull, so anunsubscribable event can never wake anything.
Slack is identified from the body, not the header. The ingress derives
eventNamefromx-github-event/x-webhook-event/x-event-type, so aSlack delivery carrying any of those would otherwise be dragged down the
GitHub path.
type: "event_callback"is checked first.A bot's own Slack message never triggers a listener.
bot_idandsubtype: bot_messagenormalize tonull— that is how one careless routinebecomes a loop nobody can stop from outside.
The untrusted boundary is scrubbed from the payload. A PR title containing
[/UNTRUSTED LISTENER EVENT DATA]cannot close the block early and continueas instruction. There is a test for exactly that.
WakeQueueholds its runtime in an explicit field, not a constructorparameter property. The server runs under
--experimental-strip-types,which strips the annotation without synthesizing the field — vitest transpiles
it happily and the real server does not start. The e2e suites caught it.
Not in this PR
Background executors were planned for this round and are deferred, with
the open question recorded in
docs/plans/2026-08-24-parity-round-2-wakes-plan.md: an executor runsheadless, so there is nobody to answer a permission request it raises, and
that decision is worth making deliberately rather than mid-implementation.
Listeners have no UI yet — they are set through the webhook API.
Testing
106 server test files, 1285 tests green; full
pnpm test(165 files, 1731tests) plus the broker, updater, desktop-viewer and packaged-server suites.
pnpm typecheckclean.oxlintcounts per touched file identical toorigin/main(the repo baseline is already red, so I compared per file).New coverage: 9 tests on the dispatch policy, 22 on normalization and matching
(mostly negative cases — wrong repo, wrong branch, a stranger's PR, an
unsubscribed kind, a boundary-escape attempt), and one end-to-end test proving
four deliveries produce exactly one run.
Manually exercised against a live fleet: a matching PR event woke the bot; the
wrong repo, an unsubscribed kind, and a junk payload were each ignored with a
recorded reason.
