## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Chat connectors store incoming messages and outgoing publications in
durable queues.
> - The app checks these queues every second, even when they are empty.
> - Empty scans keep the database active and hinder instance sleep.
> - This pull request wakes three queue workers after transactions
settle and at known retry or recovery deadlines.
> - Empty queues stop scheduling checks. Existing rows retain their
ordering, retry, and recovery rules.
## Linked Issues or Issue Description
**What existing behavior does this improve?**
Idle database activity from incoming chat deliveries, outgoing
publications, and Slack upload receipt recovery.
**Subsystem affected**
`server/` — chat delivery and background work scheduling.
**Current behavior**
The app's one-second chat timer scans the three queues together with
provider and action maintenance. Empty queues continue to query
PostgreSQL.
**Proposed behavior**
Register three independent workers with the existing delivery
coordinator. Producers announce work inside their database transactions.
Commit wakes the corresponding worker. Startup restores outstanding
work; persisted retries and stale claims supply the next deadline. An
empty queue has no recurring scan.
**Reason and benefit**
Remove avoidable queue reads without requiring a new table, an external
scheduler, or a persistent PostgreSQL listener.
**Breaking changes**
No schema or public API change. Work notifications are scoped to the
app's shared database owner. Direct SQL and independent database roots
do not send these notifications; startup still scans durable work.
**Additional context**
Refs #15625, #15750, and #15757 for the preceding sleep work. Related:
#15153 reduces chat query allocation while retaining polling. This PR
changes when the three queue workers run; it does not add query caching.
## What Changed
- Register independent incoming delivery, publication, and Slack receipt
workers on the shared scheduler.
- Add transaction work signals at queue writes, endpoint state changes,
and action transitions that unblock publications. Keep provider I/O
outside the added transactions.
- Restore deadlines from durable retry times, abandoned claims, and
publication lease expiry. Share publication and receipt eligibility
rules between dispatch and deadline queries. Respect incoming
conversation order and lifecycle dependencies.
- Exclude publications blocked by unresolved Slack tool sends. Wake them
when the tool receipt changes.
- Wake publication dispatch when an endpoint send finishes so free slots
refill. Preserve per-endpoint concurrency, conversation order, and
conservative handling of uncertain sends.
- Wake receipt recovery when a stale publication becomes
`delivery_unknown`, and wake queues when a provider connection recovers.
- Commit interaction publications with their callback tokens so dispatch
cannot see an incomplete card.
- Keep provider runtimes, other action outboxes, milestone and
wake-notice projection, Teams protocol maintenance, GitHub recovery, and
Slack session synchronization on their existing maintenance cadence.
This PR does not make the whole chat subsystem idle.
- Update the instance sleep inventory with this partial migration and
its remaining work.
## Verification
- All 1,225 PostgreSQL chat integration cases passed across the three
hosted chat shards. These cover retry and lease deadlines, blocked
followers, unresolved Slack sends, provider recovery, commit visibility,
and endpoint slot refill.
- 32 local app-wiring, queue-worker, and delivery-coordinator tests
passed after updating the wiring assertion for event-driven dispatch.
Fake timers cover an hour of idle time without queue scans.
- Related publication, interaction, receipt, and wake-notice tests
passed locally. The 13 interaction integration cases include atomic
rollback when callback-token storage fails.
- Local `pnpm typecheck`, `pnpm build`, and final server typecheck
passed. All hosted checks passed on the final commit, including build,
typecheck, test shards, release registry checks, and the canary dry run
(54 successful checks; two Storybook checks skipped for this backend
change).
- The last local PostgreSQL rerun was skipped because the embedded
database startup probe failed after five attempts. The hosted PostgreSQL
cases ran successfully; their skips only partition cases across shards.
- `git diff --check` passed. Greptile is 5/5 on the final commit with no
unresolved findings.
## Risks
- Every producer that makes queued work eligible must send a transaction
work signal. The tests exercise commit visibility, concurrent wakes,
worker failures, and restart recovery. Future direct SQL writers must
participate in this contract.
- The existing database work-signal layer reconciles uncertain
transaction outcomes. This PR adds no work-signal table or schema
migration.
- Provider and action maintenance still polls. Further changes are
required before an idle chat-enabled instance can sleep.
- Tests use real PostgreSQL with simulated provider responses; they do
not send messages through live provider accounts.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Heartbeat prepares, dispatches, and completes each agent run.
> - After the runtime-selection extraction, the main service still had
7,295 lines.
> - Provider dispatch and workspace finalization formed one large block
with shared cleanup rules.
> - This pull request moves that block into a typed runtime-execution
module.
> - The service now has 6,417 lines. Readers can follow admission and
outer cleanup without reading the provider execution details.
## Linked Issues or Issue Description
Follow-up to #15746. I searched open heartbeat PRs and issues. I found
no competing runtime-execution extraction.
**What existing behavior does this improve?**
The organization and test coverage of native and legacy heartbeat
execution.
**Current behavior**
The heartbeat service contains a 912-line block for provider dispatch,
usage capture, workspace finalization, and instruction cleanup.
**Proposed behavior**
Move that block to `server/src/services/heartbeat/runtime-execution.ts`.
Keep the atomic dispatch gate, admission, terminal run status, and outer
lease cleanup in the service. Preserve run behavior.
**Reason and benefit**
This gives runtime execution a named boundary and direct tests. It
removes 878 lines from the main service in one bounded change.
**Breaking changes**
None intended. There are no schema, API, or policy changes.
## What Changed
- Add `executeHeartbeatRuntime` for prepared native and legacy
execution, usage capture, workspace finalization, and
gateway/instruction cleanup.
- Return an explicit dispatch result. Update outer ownership state
through immediate callbacks, including before exceptions. Read
instruction state through live getters.
- Move the two internal recovery error classes with their existing
behavior. The caller imports the same classes for `instanceof` checks.
- Add 15 database-backed execution tests. Keep the existing heartbeat
regression suites.
- Repair the native Stop acceptance fixture: installed Codex now takes
precedence over `PATH`. A test-only loader pins the fake provider. An
isolated home and dummy key keep readiness offline. Add four loader
tests.
- Document the module boundary and fixture setup.
## Verification
- Passed: eight focused heartbeat suites (483 distinct tests, including
15 new execution tests). The boundary suite passed again after adding
the failed-restore retention case from review.
- Passed: `node --test
tests/e2e/fixtures/composer-stop-codex-loader.test.mjs` (four tests).
- Passed: `pnpm -r typecheck` and `pnpm build`.
- Passed: AST comparison of all 912 moved lines after the explicit
boundary substitutions. SQL template text, recovery class bodies, public
exports, and the rest of the executor match the baseline.
- Passed: browser Stop journeys for legacy process and native Paperclip
Runner (two tests). The native fixture log proves provider `turn/start`
before Stop and `turn/interrupt` after Stop.
- Passed: all three ACP continuation browser journeys (same-session
queued input, no replay of an interrupted write, and a new direction
after composer Stop). Five relevant browser journeys passed in total.
- Passed: the full CI test groups, including all server, chat,
workspace, serialized-server, runner, and browser shards.
- Local full-suite limitation: `pnpm test:run` first hit the macOS
shared-memory segment limit while starting embedded PostgreSQL. After
releasing only this task’s unused acceptance-server segments, the retry
progressed without reported failures. I stopped that duplicate run after
the full CI test groups passed.
- Passed: all 56 PR checks/statuses on
`8694c116e8d43ed8ac11bc4c58623ea3af34a675`. Greptile is 5/5 with no
unresolved review threads.
## Risks
- Cleanup depends on state written before an error. The module reports
dispatch, retention, and recovery ownership immediately. Tests cover
early returns and exceptional cleanup.
- Instruction callbacks can replace saved metadata during execution.
Live getters preserve those changes.
- Native acceptance uses a real server, database, browser, and Rust
runner with a deterministic provider. It does not verify a live provider
service.
## Model Used
OpenAI Codex, GPT-6 family, with reasoning and repository/tool access.
The exact serving model ID and context-window limit were not exposed in
this session.
