DottaandPaperclip e40de0c9e8 perf(ci): refresh test weights and narrow graph dependencies (#18464)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Contributors need fast, reliable CI feedback.
> - Diff-aware CI selects test files and partitions them into runner
jobs.
> - Stale cost estimates put several slow suites on the same runner.
Broad imports also couple small tests to large modules.
> - This PR refreshes test costs, runs independent graph discovery in
parallel, and narrows three dependency boundaries.
> - Selection safeguards and CODEOWNER-only AWS routing stay in force.

## Linked Issues or Issue Description

Refs #18398. This follows the audit of [PR #18427's verification
run](https://github.com/paperclipai/paperclip/actions/runs/41169978784).

The audit found 403 selected general-server files without timing
weights. Three suites measured at 232s, 122s and 116s shared one shard
because each received a roughly 2s fallback weight. Local graph
discovery across four projects took 43.7s serially and 21.7s with two
workers. A reverse-order repeat took 37.7s serially and 22.6s with two
workers. Both comparisons produced identical selection results. This is
a local measurement, not a claim about production CI speed.

## What Changed

- Refresh general-server costs for 1,285 of 1,309 current files and
serialized costs for all 163 files from two successful protected-master
Cloud readiness runs. Retain prior costs for unmeasured files, including
dedicated chat and native-runner suites.
- Record passing server file costs, including collection, setup and
environment preparation. A weekly hosted workflow validates trusted
source runs and opens a timing-only PR. It tests shard coverage, pauses
while a refresh PR is open, and never merges automatically.
- Discover at most two project graphs concurrently in isolated,
heap-limited Node processes. Cache repeated inventory reads within one
selection. Worker errors and timeouts retain the full task plan.
- Fetch only the merge commit and parents for the selector. A real
shallow-clone regression proves the complete diff still includes more
than 300 files, renames and deletions.
- Share the identical log viewer and run details between both
AgentDetail pages. The viewer test imports the shared implementation and
runs each of its 13 distinct cases once.
- Extract the pure API error class while preserving the API client's
public exports. Import delivery work signals through their existing
narrow DB export.

## Verification

- PASS: `pnpm -r typecheck` and `pnpm build`.
- PASS: 284 CI selection, timing, shallow-diff, sharding and routing
tests.
- PASS: 74 further cache, routing and graph-proof tests.
- PASS: 94 targeted UI assertions across the viewer, run invocation, API
errors/client and progress helpers. All 76 assertions in the 12 server
suites made independently selectable also pass.
- PASS: `pnpm check:token-gates`, module-boundary checks, YAML parsing
and `git diff --check`.
- PASS: [Full PR CI and required `ci / verify`
aggregate](https://github.com/paperclipai/paperclip/actions/runs/41206683345),
including all 12 general-server shards, all nine serialized shards,
workspace groups, chat suites, Runner lanes and build checks.
- PASS: [GitHub hosted real-workspace selector and cache/routing
qualification](https://github.com/paperclipai/paperclip/actions/runs/41206683205).
- PASS: Both Greptile and Paperclip reviews are 5/5 with no actionable
findings or inline comments on `7dc65c51b8`. The PR has no merge
conflicts.
- PASS: The production refresh parser accepted all 107 structured
file-cost records from a real successful server CI job, including
setup/loading cost.
- Local `pnpm test:run` completed all six chat shards successfully. The
duplicate monolithic local run was stopped after the complete remote
suite passed; it was not completed locally.

The focused log-viewer command improved from 18.84s (26 duplicate
variant cases) to 8.49s (all 13 distinct behavior cases). The dependency
audit confirms 12 server files and the API-error test no longer need
conservative always-run retention. Repartitioning the audited PR with
the new costs changes the slowest shard from 810s to 591s of summed
historical test execution (1,124 of 1,142 files measured). This is a
workload simulation, not measured new CI wall time.

## Risks

- Two graph processes use more peak memory. Each has a 2 GiB heap limit
and a three-minute timeout. Any failure preserves the original task
plan. Real workspace qualification runs in GitHub CI.
- Historical logs contain test/hook costs only. New reporter records add
loading/setup costs after merge. The manifests identify measurement
coverage and source runs. These weights change placement, never
permission to skip tests.
- Runner load adds timing noise. The refresh uses medians and requires
at least 90% measurement coverage in each lane.
- GitHub may require approval to run checks on a PR created with
`GITHUB_TOKEN`. Refreshes remain reviewable and do not merge themselves.
- The shared viewer is a mechanical extraction. Both pages retain their
existing exports, and the behavior assertions remain covered. AWS runner
authorization is unchanged.

## Model Used

OpenAI Codex, GPT-6, with repository inspection, reasoning, code
execution and GitHub tools. The exact deployment ID and context-window
size were not exposed in this session.

DottaandPaperclip f52da40f08 fix: resume queued turns after maintenance (#17967)
Keep an accepted turn's starting input in task history, show its admission wait, and resume existing queued runs promptly when maintenance ends or expires.

Verified with behavioral red/green regressions, real PostgreSQL and process execution, browser/native Runner acceptance with a deterministic provider, workspace typecheck, production build, and current-head CI/review.

DottaandPaperclip 623f1dc289 fix(server): schedule secret-proposal expiry from committed changes (#17446)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents can propose secrets and bindings for approval.
> - Pending proposals already contain their expiry and encrypted value.
> - The server scans for expired proposals on every maintenance tick,
even when none exist.
> - Committed proposal changes and saved expiry times provide the
required triggers.
> - This PR uses those triggers and preserves scrubbing, approval
checks, and recovery.
> - Empty and completed proposal history no longer causes recurring
expiry queries.

## Linked Issues or Issue Description

Refs #17443. This is the second PR in the sleep migration stack and
targets its branch.

**What problem does this solve?**
The periodic proposal scan contacts PostgreSQL when no proposal needs
maintenance. That obstructs idle database behavior across tenant
instances.

**What is the proposed solution?**
Use transaction-aware notifications for creation and resolution.
Reconstruct the earliest pending expiry at startup. Run cleanup at that
deadline, or retry while reconciliation remains unfinished.

**Why is this useful?**
It removes an idle scan while retaining security checks and physical
ciphertext cleanup. No queue table or migration is required.

## What Changed

- Added intent notifications before secret/binding creation, approval,
terminal transitions, and linked interaction resolution. The existing
outer transaction owns settlement.
- Kept expiry selection, ciphertext scrubbing, dependent rejection, and
authorization in the secret-proposal service.
- Registered a startup and deadline worker in place of the aggregate
maintenance sweep. Empty/terminal states disarm; overdue batches and
failures retain retries.
- Reused shared scoped deadline dispatch for secret expiry. The service
owns company-filtered SQL and expiry policy. Custom-image expiry
continues to use `registerDeadlineWork`.
- Added real PostgreSQL producer, outer-transaction, concurrent-write,
expiry, restart, interaction resolution, and drain/resume tests. Updated
startup wiring fixtures and documented the supported writer/lifecycle
contract.

## Verification

- Landing reconciliation at `c10eb1bcf752b058713e05d3345e5cf38dd3fa72`:
160 tests pass across the complete secret-proposal, scoped deadline,
company batch, coordinator, startup, custom-image service and
custom-image worker suites; no cases skipped in the accepted runs.
Server typecheck passes. This integrates master after #17443 landed;
fresh remote CI and Ponytail review are required before merge.

Current head: `5bbe17ad9ebc4573b08ed1a9323644ef9608ca09`. This remains a
single-duty PR stacked on #17443.

- Integrated pinned master `8548173fc9efdc0fa07644fb92dcc0b6851a95e5`
with normal merges. Every branch passed generated-schema checks and its
target-branch migration-order gate. Existing SQL is unchanged; the 25
stack migrations follow master’s new migration.
- Duty-specific producer coverage, lifecycle tests, and earlier failure
records:
[2026-10-08-instance-sleep-and-scheduler-inventory.md](https://github.com/paperclipai/paperclip/blob/5bbe17ad9ebc4573b08ed1a9323644ef9608ca09/doc/plans/2026-10-08-instance-sleep-and-scheduler-inventory.md),
[2026-10-24-recurring-server-sleep-stack.md](https://github.com/paperclipai/paperclip/blob/5bbe17ad9ebc4573b08ed1a9323644ef9608ca09/doc/plans/2026-10-24-recurring-server-sleep-stack.md).
- Combined tip `51e6cbe67979b55b340ea9f0f434c5b5c682ccd6`: **355
startup/cancellation/recovery/dispatch/preservation tests**, **75
connection-management tests**, and production server typechecking pass.
These combined checks do not mean every intermediate PR independently
ran the full repository suite.
- Real master-to-stack database upgrade passes: **379 unchanged prior
migration receipts plus 25 new migrations**, with the gateway
responsibility fixture preserved.
- Owning-branch checks: 84 runner installation/settlement cases plus
runner typechecking and generated TypeScript/Rust profile agreement; 253
GitHub review workflow cases. Stop-attribution and held-worker readiness
regressions failed before their fixes.
- Failure accounting: the initial combined run passed 349 cases and
failed six idle assertions in a reused preservation database containing
old cancelled runs. Repeating the combined command with a fresh
preservation database passed. Earlier invalid project selection, merge
import/type errors, and the interrupted full local suite are not counted
as passing checks.
- **Latest-head CI and review remain required.** Prior CI findings
include GitHub idle observation, route teardown, attention cleanup,
touch-picker E2E, workspace health, and voice-cleanup timing; local
passes do not erase those failures. No full local repository-suite,
deployed sleep, fleet cost, or live Copilot qualification claim is made.

## Risks

- Notifications cover supported writers sharing the database signal
owner. Independent SQL writers and other process roots require a
separate ingress contract; startup recovery alone is not live replica
support.
- The shared coordinator and scoped worker also serve later stack
duties. Their defaults remain intact; existing voice, chat, native, and
startup consumers are included in integrated verification.
- Startup now checks overdue proposals immediately. During drain,
physical cleanup waits; approval still rejects expired proposals
synchronously.
- Each due company pass remains bounded to 100 rows. Failed scopes back
off from 30 seconds to five minutes; healthy overdue work keeps
draining. Self-generated write hints coalesce and do not erase a failed
sweep's backoff.
- Heartbeat-disabled behavior and Cloud sleep-safety gates remain
unchanged. This does not establish deployed suspension or external wake
coverage. Tool review and gateway token cleanup remain separate slices.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning and code execution. The exact
serving model identifier and context window were not exposed.

DottaandPaperclip 30b753f614 perf(budgets): scope accounting and deliver enforcement asynchronously (#17046)
## Thinking Path

> - Paperclip manages AI agents and their paid work.
> - Budgets must prevent new work and stop reported overruns.
> - Cost settlement also ran serial lifecycle reconciliation for every
eligible company agent.
> - That made request latency grow with unrelated idle agents and
delayed results on stop delivery.
> - This change separates atomic admission and accounting from durable
asynchronous enforcement.
> - Scoped live usage detects overruns without writing provisional
ledger charges.
> - The result is constant query scope for ordinary settlement and
recoverable stop delivery.

## Linked Issues or Issue Description

**What happened?**

Settlement and budget checks entered company-wide lifecycle
reconciliation. A company with 1,000 unrelated idle agents performed
1,001 accounting transactions for one ordinary cost evaluation. User
requests could also wait for provider termination. Running usage
checkpoints did not enforce reported monetary exposure.

**Expected behavior**

Keep the final reservation gate authoritative. Commit charges, scope
blocks, and enforcement intent before returning. Deliver stop requests
after commit. Read only applicable policies and execution scopes for
ordinary charges. Stop long-running work when supported reported or
priced usage establishes an overrun.

**Steps to reproduce**

1. Create a disposable company with one company budget and idle agents.
2. Evaluate a charge below the budget with 0, 17, and 1,000 unrelated
idle agents.
3. Compare query counts, company accounting transactions, and duration.
4. Use the controlled partial-usage and delayed-stop fixtures to check
enforcement and request responsiveness.

**Paperclip version or commit**

The measured baseline is `6c9b87d0922f1ebfc43e8b0c36889ac5ba7b9837` from
`master`.

Related public work: Refs #16976, #2006, #3539, #13763, #14296, #16853,
#13075. These cover the affected service charge, cancellation, and
accounting paths. This change removes their shared reconciliation
overhead.

## What Changed

- Batch applicable policy exposure under the existing company accounting
lock. Preserve exact fractional money and zero-reservation dispatch
fences.
- Commit a durable final budget dispatch claim before provider I/O.
Retain a separate final issue/run ownership transaction through
synchronous handoff, without holding the company accounting lock or
awaiting provider work. Preserve native recovery lease checks and
duplicate handoff fencing. Browser handoff rechecks current policy; it
reuses a consumed rate slot only for the identical policy generation.
- Separate ledger spend, live observed spend, and effective held
capacity. Use the maximum of reservation and live observation for each
unfinished operation.
- Deliver budget cancellation through the existing coordinator.
Revalidate generations and persist queued/running stop fences before
external termination. Bound stop concurrency to four.
- Apply agent holds only to the affected agent. Project budgets leave
other projects running. Project real company transitions in bounded
lifecycle batches.
- Replace periodic broad reconciliation with durable pending work,
startup repair, receipt replay, and concrete retry/window deadlines.
Retain drain and idle-safety checks.
- Enforce accepted cumulative usage checkpoints without provisional
charges. Final accounting atomically replaces live exposure and settles
reservations.
- Add operator-gated budget spans, regression coverage, map updates, and
a real-PostgreSQL comparison harness. No schema or first-party telemetry
change.

## Verification

- Full workspace `pnpm -r typecheck` passes on the final ownership fix,
rebased onto `bbcf5dfe98`. Production `pnpm build` passes on final head
`4c5f4de8b1`. Map, module-boundary, token, and Storybook catalog checks
pass.
- Focused real-PostgreSQL coverage includes the 292-case rebased
accounting/dispatch run, 63 browser cases, 52 run-control/cancellation
cases, 42 policy-generation cases, 77 lifecycle/commentary cases, and
the exact Muse confirmation regression. Native executor unit coverage
passes all 768 cases. Final ownership coverage passes: 74
adapter/use-case cases, nine public regression cases, and the additional
deleted-project race. These exercise competing ownership, budget changes
and charges between phases, zero/nonzero duplicate claims, rollback,
recovery contention, read-only capacity rechecks, and controlled HTTP
startup after commit. Another 74 pure/startup/tracing cases pass. The
complete CI matrix and both 5/5 reviews passed on `1ac9b58`; its
external security scan identified a stale-owner handoff race. The final
fix restores synchronous issue/run ownership fencing after the
accounting transaction commits. Final head `8e84f55ce8` has fresh
Greptile 5/5 with zero new comments, Paperclip review 5/5, and a passing
security scan. The complete latest-head [CI
matrix](https://github.com/paperclipai/paperclip/actions/runs/39535189808)
passes, including budget, browser, Runner, build, and canary jobs. The
unchanged Runner close fixture passed on its sole same-head job retry.
- Broad local `pnpm test:run` invocations were stopped before required
source updates (rebase and review fixes). They are not claimed as full
passes. Final full-suite coverage comes from the complete latest-head CI
matrix; local focused coverage and the incomplete broad invocations are
reported separately.
- Reproduce performance with `pnpm --filter @paperclipai/server exec tsx
../scripts/benchmark-budget-enforcement.ts
--baseline-ref=6c9b87d0922f1ebfc43e8b0c36889ac5ba7b9837`; repeat with
`--reverse`. The harness uses disposable real PostgreSQL, 20 warm
samples per variant/count, and records raw timings, SQL/lock counts,
agent reads, unchanged agent state, and query plans. Final
production-source measurement revision:
`eff713a4f72c7f4b7a4002a701cb481d4bfccd95`; the extended harness is
committed in `4c5f4de8b1`.

| Unrelated idle agents | Baseline median / p95 | New median / p95 |
Baseline SQL / locks | New SQL / locks | New agent reads |
| --- | ---: | ---: | ---: | ---: | ---: |
| 0 | 1.80 / 2.33 ms | 2.99 / 3.88 ms | 5 / 1 | 7 / 1 | 0 |
| 17 | 15.53 / 19.55 ms | 2.24 / 2.60 ms | 90 / 18 | 7 / 1 | 0 |
| 1,000 | 978.35 / 1,790.43 ms | 2.16 / 2.52 ms | 5,005 / 1,001 | 7 / 1
| 0 |

- These measurements use local PostgreSQL 18.1 and Node 26.4.0 arm64.
They isolate the cost-evaluation core and complete admission path,
without hosted-region or provider latency. Prior-revision reversed-order
controls also preserved the constant query counts; the final
measurements above use the final production source.
- Complete reserve → final ownership gate → immediate offline provider
result is measured separately, with one responsible agent and one active
operation at each unrelated-agent count. Admission p95 baseline/new: 0
agents **11.54 / 29.77 ms**; 17 agents **9.31 / 27.62 ms**; 1,000 agents
**24.51 / 74.05 ms**. Baseline admission was already scoped; the
stronger final fence adds bounded overhead. New counts stay constant at
53 Drizzle statements, three transactions, two company-accounting locks,
and five agent-reading statements bound to the responsible agent. Zero
unrelated-agent reads, exactly one provider callback per sample, and no
leftover runs or holds. All admission scenarios stay below 250 ms. No
external provider calls are included.
- The partial-usage/delayed-termination fixture passed 20/20: receipt
persistence p95 13 ms, receipt return to observed durable Stop fence p95
28 ms, complete receipt-start-to-fence p95 50 ms, unrelated database
request p95 1 ms while termination was blocked. After releasing the
controlled termination fixture, acknowledgement p95 was 14 ms. These are
separately measured phases; fixture acknowledgement is not live-provider
termination latency.
- Models and provider deadlines are unchanged. No deployment, live
inference, or staging acceptance is claimed. A quiet 30-minute follow-up
waits for the merged revision on staging, then repeats classifier and
controlled budget-stop acceptance in staging, recording hosted
bookkeeping, queue delay, and actual provider acknowledgement
separately.
- Development failures retained: finalizer notification regressions
(fixed; 27/27 affected cases passed), invalid browser admission fixture
assumptions (fixed; browser coverage now passes 63/63), and first-head
lifecycle/dispatch CI regressions (reproduced and repaired). A
prior-head Cases E2E test hit its unchanged announcement-dismiss handler
race while opening a filter; the same journey passed on `1ac9b58`. The
external security review then found a stale-owner race between
accounting commit and provider entry; final verification covers a
competing run in that gap while retaining provider I/O outside the
accounting lock. Early PostgreSQL startup attempts hit local semaphore
pressure; serial reruns succeeded. The final-head Runner lane had one
failure among 1,823 tests: the unchanged `timeout-attachment` fixture
failed at its first process close after 6.28 seconds. The sole same-head
job retry passed all 1,819 active tests (four skipped), including that
fixture in 1.85 seconds. Three isolated local probes could not run
correctly because the Rust fake-provider fixture binary was absent;
cleanup masked the original startup failure. CI builds that fixture
through its normal lane. These probes are inconclusive and are not
counted as passes.

## Risks

- This changes accounting, lifecycle, and cancellation ordering. Durable
generations, source/sequence checks, ownership leases, and company
locking remain required for correctness.
- Provider stop acknowledgement can be slow or fail. Stop intent remains
pending until existing termination proof succeeds; cancelled row status
alone does not acknowledge delivery.
- Mid-run limits depend on provider usage reports or supported price
calculations. Providers that report only at completion cannot provide
exact mid-call detection.
- Signals are process-local wake hints for the supported
single-active-writer model. Durable state and startup recovery remain
authoritative.
- There are no migrations, new queue tables, or cached balances. Repeat
the classifier and controlled budget-stop acceptance after normal
rollout.

## Model Used

OpenAI Codex, based on GPT-6, with reasoning, tool use, code execution,
and parallel coding agents. The host does not expose the exact backend
model revision or context-window size, so those values are not asserted.

Devin FoleyandPaperclip 4415665d67 fix(server): allow proved idle waits and verify historical cleanup (#16633)
## Thinking Path

> - Paperclip manages agents, task continuations, integrations, and
their execution resources.
> - Automatic idle sleep needs durable evidence that accepted work and
provider cleanup are settled.
> - Response-driven questions, passive board escalations, and completed
connection receipts currently look like unfinished work.
> - Legacy ephemeral leases and terminal image sessions need actual
deletion proof before their history can become idle.
> - This PR adds narrow evidence-based exceptions and read-only provider
verification while preserving queues, outcomes, and ownership fences.
> - Idle instances can sleep without losing responses, automatic
reconciliation, or cleanup obligations.

## Linked Issues or Issue Description

**What happened?**

Instances with no executable work can remain awake because pending human
responses, passive recovery records, outbound integration configuration,
or completed delivery history are counted as background work. Older
failed ephemeral leases and finished setup sessions also lack the
evidence needed to distinguish retained resources from deleted
allocations.

**Expected behavior**

Permit idle sleep only for proved response-driven waits and settled
history. Continue blocking real queued work, inbound integrations
without a wake contract, unfinished accounting/retries, retained
resources, and uncertain provider cleanup.

**Steps to reproduce**

Finish an issue's producing run, leave a pending question or
confirmation, and request an owned scheduled idle report. Separately
retain a processed connection receipt or a failed ephemeral lease whose
provider allocation has already been deleted. The old checks keep those
instances awake even after executable work has finished.

Related public groundwork: #15522, #15599, #15761, #15897, #15907, and
#16325. Searched existing public idle-sleep PRs; this addresses
additional blockers in the current predicates.

## What Changed

- Recognize supported response-driven waits and passive board recoveries
without changing task state, response audiences, or continuation
policies. Bind passive issue generation into routine-only alarms too.
Keep automatically polled merge-confirmation cards awake.
- Treat processed events, delivered intents, disabled drafts, and
outbound MCP configuration as history/configuration where proved safe.
Preserve pending deliveries, downstream wake requests, and inbound
GitHub bindings.
- Permit only pristine Slack setup drafts with a matching disabled
channel connection, no provisioning registration, and no prior provider
identity/activity. A saved slash-command name remains inert
configuration.
- Repair missed routine execution-issue status hooks in bounded
awake-only maintenance. Lock and re-read exact owners, apply existing
completion/transient-failure rules, and preserve normal continuation
after an issue resumes.
- Allow human-only connection setup to wait only when no reusable active
connection of its purpose exists; available access reblocks sleep for
reconciliation. The delivery worker shares this proof, releases its
local idle hold, and retains maintenance only while already awake.
Passive-only ticks pause before admission during an owned drain,
allowing slow backups to finish; new producer notifications still
reconcile and invalidate the backup.
- Add optional `environmentInspectLease` SDK discovery/dispatch and
read-only Daytona/fake-provider implementations. Old workers remain
conservative. Daytona status inspection uses a fresh provider GET
without reconnecting or poisoning unused-worker eligibility.
- Bind historical credential reads to an unrotated initial secret
version and its immutable resolved-value hash; reject ambiguous
histories and ambient Daytona credential/API-endpoint fallbacks before
querying provider state.
- Verify bounded rotating batches of historical resources on
already-awake Cloud instances, outside readiness. Store host-owned
deletion evidence bound to exact row identity/version and reject
concurrent ownership changes. Preserve failure outcomes, cleanup/export
intents, and run continuation authority.
- Preserve cancellation provenance, defer contended routine rows
individually, and cap actual inspection RPCs across caller timeouts and
worker exits. Add database, SDK, provider, configuration-scope, and race
regression coverage and update idle protocol documentation.

## Verification

- `pnpm -r typecheck` and `pnpm build` passed on `24fd1c0f5ec`; server
typecheck/build passed again after the final coordinator-only fix in
`60f23e6e4b6`.
- Final server regressions: 258 sleep-safety/connection cases and all 17
coordinator cases passed. Earlier focused checks also covered 331
combined idle/cleanup cases, 34 custom-image cases, 39
credential/cleanup cases, 39 connection-history cases, and 80 existing
routine cases. Counts overlap and are not additive.
- SDK: 153 passed. Daytona: 406 passed with 14 existing opt-in skips.
The provider implementation also typechecks against the locked SDK used
by the Cloud wrapper.
- Dependency boundaries were exercised with real child workers holding
provider inspection replies beyond caller timeouts, a real PostgreSQL
row lock delaying one routine owner, and real connection creation →
queue notification → worker hold release → resumption after access is
enabled without another notification. A controlled six-second backup
goes through the real coordinator, task drain, work signals, and
idle-safety generation checks; maintenance permits completion, while a
new committed transaction invalidates it.
- Full local `pnpm test:run` completed its general-server phase with
21,122 passing, 29 failing, and 109 skipped tests; later phases did not
run. That long run spanned source edits and is not a final-revision
pass. The affected Slack draft assertion passes on current source.
Restoring `/usr/sbin` for `lsof` produced 233 passing tests and two
Git-fixture failures across the other five files (3 existing skips).
Both remaining assertions pass with command-scoped
`init.defaultBranch=master`; this host defaults to main and leaves both
branches in their fixture. No source/global Git setting changed for that
comparison. Original failure logs are retained.
- A parallel typecheck/build attempt raced generated Runner outputs and
failed an import. Running the build sequentially passed with no source
change.
- Local database checks use the maintained test-constructor seam with
native PostgreSQL 16.14 because bundled PostgreSQL 18 is unreliable on
this host. No database assertions were skipped in the focused runs. An
interrupted combined run was superseded by the separate passing
coordinator and safety/connection runs; no owned test database processes
remain running.
- Apex reviewed final head `60f23e6e4b615a08591e19d86443a6c35c091ce1`:
**5/5**, zero unresolved threads. All current-head CI gates are green,
with expected policy skips. The branch is conflict-free and GitHub
reports a clean merge state.
- Current-head CI initially failed `plan-task-fixture.spec.ts:66` during
fixture deletion: the final company DELETE hit
`activity_log_company_id_companies_id_fk` after the feature assertions
completed. The deletion path is unchanged here; the final diff only
changes drain-gated passive maintenance. The preceding revision passed
this shard. Failure evidence is retained in [the original CI
job](https://github.com/paperclipai/paperclip/actions/runs/39006936642/job/117321244396);
the targeted retry passed on the unchanged commit ([retry
job](https://github.com/paperclipai/paperclip/actions/runs/39006936642/job/117322535013)).
This shows recovery, not that the underlying company-deletion race is
resolved.
- These checks do not claim staging/production deployment or live
provider cleanup proof. Provider tests simulate responses. Full Cloud
staging verification requires a compatible Core/private-plugin
composition after the Core revision is on master.

## Risks

Sleep eligibility changes require the existing owned drain, final
generation validation, local-work checks, and plugin drain. Unsupported
states fail closed. Queued agent input and routine execution remain
blocked. Outbound MCP exemptions exclude inbound GitHub grants; other
unsupported inbound integrations remain awake.

The inspection RPC is optional and requires a matching live worker
method. Its actual outstanding calls are capped at two across workers
even after the caller times out. Historical lease inspection requires
its recorded plugin/config; setup inspection requires an unchanged
recorded config fingerprint. Not-found under replacement account
credentials is not historical deletion proof: ambiguous/rotated secret
histories defer verification, and initial-version reads must match their
recorded value hashes. Missing provenance (including legacy image
sessions without a recorded config fingerprint), live/stopped resources,
provider authorization failures, and concurrent changes defer
verification. Routine repair replays existing
completion/transient-failure behavior and timestamps at reconciliation
time; it does not execute or discard deferred comments. No migration or
destructive provider operation is added. The new marker does not grant
run-resume authority. Full Cloud staging validation requires a
compatible Core/private-plugin composition; no production deployment is
included.

Nicky LeachandPaperclip d1463fb79e Preserve saved delivery deadlines across clock ticks (#16589)
## Thinking Path

> - Paperclip manages AI agent work and message delivery.
> - Delivery workers restore saved retry and maintenance deadlines.
> - The coordinator converts each future deadline to a delay and back.
> - A clock tick between those reads can move the deadline.
> - This pull request keeps the saved future timestamp.
> - A deterministic test covers the clock tick.

## Linked Issues or Issue Description

Refs #16503. This separate fix addresses an unrelated CI failure found
during its review.

**What happened?**

The unchanged delayed GitHub publication restart test intermittently
reports a wake deadline one millisecond after the saved timestamp. The
coordinator subtracts one clock reading from the deadline, then adds the
delay to a later reading.

**Expected behavior**

Keep a future saved deadline exactly. Preserve the current retry
behavior for expired deadlines during idle reconciliation.

**Steps to reproduce**

Register a task with a future `nextRunAt` timestamp. Advance
`Date.now()` by one millisecond on each read. The old coordinator
reports `nextWakeAt()` one millisecond after the saved timestamp. The
new unit test forces this sequence.

## What Changed

- Let the internal scheduler accept the existing absolute future
deadline.
- Keep relative retry and immediate wake scheduling unchanged.
- Add a deterministic advancing-clock regression. Keep the chat
integration assertion unchanged.

## Verification

- Based on `origin/master` at `c91f7a6e5f`.
- Coordinator suite and the unchanged delayed GitHub publication restart
case: 16 passed, 1346 unrelated cases skipped.
- The new regression fails against the original coordinator with the
exact one-millisecond offset.
- Server typecheck passed.
- On head `d2db3e15d6dfafd390bab59529474abebb19d09c`, all 55 hosted
checks passed, with 2 expected skips. This includes all server/chat
shards, Runner checks, build, canary dry run, security checks, and
end-to-end tests.
- Standard Greptile and Apex are both 5/5 on that exact head, with no
review threads. Apex completed after green CI; final CI verification
remains fully green and the branch is mergeable.
- `git diff --check` and the pre-push secret/PII scan passed.

## Risks

Low risk. The change keeps the saved future timestamp. Existing tests
cover retry, idle drain, preemption, and shutdown behavior. No schema or
API change is required.

## Model Used

OpenAI Codex, GPT-6, with reasoning, repository inspection, code
execution, and testing. The exact deployment model ID and context window
are not exposed in this session.

Devin FoleyandPaperclip 78b833c495 Dispatch routine and monitor work at saved deadlines (#16514)
## Thinking Path

> - Paperclip manages work that agents run for a company.
> - Routines and issue monitors store their next run time in the
database.
> - The app currently waits for the heartbeat interval to find that
work.
> - This can delay work after a workspace wakes before its saved
deadline.
> - This pull request uses the existing work coordinator to schedule
each known deadline.
> - It also parses each cron expression once, so sparse schedules do
less work on the event loop.
> - Agents can start due work sooner while the existing execution checks
stay in place.

## Linked Issues or Issue Description

**What happened?**

Routine and issue-monitor dispatch depends on the heartbeat scan
interval. A workspace can wake early and still wait for the next scan. A
sparse cron search also parses the same expression for every minute it
checks. In a local annual-schedule test, the deadline callback ran on
time but schedule calculation delayed the routine record by 13.6
seconds.

**Expected behavior**

Use a saved future deadline to request the existing dispatch scan.
Restore deadlines at startup and update them after a producer
transaction settles. Do not let future timers keep an idle workspace
active. Parse a cron expression once for each search.

**Steps to reproduce**

1. Set an active routine and an assigned issue monitor to the same
future deadline.
2. Choose a deadline between heartbeat scans. Use an annual routine
expression to exercise a sparse search.
3. Compare the saved deadline with the routine firing and agent start
times.

**Paperclip version or commit**

Source checkout based on c7ea5c0216.

Related public changes: #16215 reports routine deadlines for external
wake. #8034 caches time-zone formatters in the cron search. This change
reuses those contracts.

## What Changed

- Register separate routine and issue-monitor workers with the existing
delivery coordinator after startup housekeeping.
- Restore the earliest eligible future deadline from the database after
each scan.
- Notify the matching worker when routine or monitor writes settle,
including the native `set_task_monitor` tool. Keep the heartbeat
interval as a recovery scan for blocked or externally written work.
- Retain the scan-start cutoff so a deadline crossed during a slow scan
receives an immediate follow-up scan.
- Retain the coordinator gates for standby, idle drain, and shutdown.
Future timers do not count as active work. Bound expired deadline
retries during idle reconciliation so a paused worker cannot spin.
- Parse a cron expression once during a next-run search. Skip impossible
UTC dates before time-zone formatting. Preserve the existing calendar
and time-zone matching.
- Add clock, transaction, failure, SQL eligibility, and producer
notification tests. Document the scheduler behavior.

## Verification

- `pnpm -r typecheck`: passed.
- `pnpm build`: passed.
- Full CI, browser tests, and security scan: passed on final head
9fc857dcec. Greptile Apex is 5/5 with no
unresolved comments.
- Final focused startup, deadline, routine, SQL eligibility, native
monitor, cron, and coordinator tests: 159 passed across seven suites.
The crossed-deadline and native-notification regressions failed before
their fixes.
- CI caught the existing startup suppression assertion. It failed
locally before restoring the outer timer-dispatch guard; all 38 startup
tests now pass.
- A canceled-drain regression also failed before the fix. Future timers
keep their saved time; only expired deadlines use the bounded idle
retry. Server typecheck and build passed again.
- The idle-drain regression reproduced 22 checks in 20 ms before its
fix. After the fix, 43 coordinator and related worker tests passed.
Server typecheck and build passed again after the review fixes.
- The broad local `pnpm test:run` attempt reported existing
host-sensitive failures. Two Git fixture tests fail identically on
unchanged c7ea5c0 because the host default `main` leaves an extra branch
in an intended master-only remote. Both pass with a command-scoped
`init.defaultBranch=master` setting. No Git settings were changed on
disk.
- A diagnostics test also fails on both unchanged master and this branch
because its broad `private` substring assertion matches the canonical
macOS temporary source path in an error stack. A local Anthropic hire
assertion failed only in the broad run; all 70 tests in that file pass
on both source revisions when run separately. Its broad-run cause is not
determined. These failures remain recorded. The full exact-head CI
matrix passed; the broad local development attempt was then stopped.
- An earlier full run was interrupted after PostgreSQL reported host
shared-memory exhaustion. One retry was stopped when timing required the
UTC optimization. Acceptance then used an owned database on the existing
local PostgreSQL service. No shared services were stopped or reset.
- Local dispatch: routine record at +0.102 s, routine agent start at
+0.171 s, monitor agent start at +0.159 s. Both scripted agents
succeeded using real run-scoped API authentication. No model provider
was called. No duplicate runs occurred during the 70-second follow-up.
Platform: macOS, Node 25.6.1, isolated database on local PostgreSQL 16,
source checkout. The final run used a fresh database and a clean
checkout of 9fc857dcec.
- The first timing run exposed the repeated cron parsing described
above. A diagnostic run showed the timer fired 1 ms after the deadline
while the annual search blocked the event loop. Parsing once reduced
local dispatch to 5.9 seconds, which still missed the five-second test
target. The next change skips impossible UTC dates before formatting. A
second regression failed before that fix. The final timing result and
duplicate check passed.
- A separate acceptance setup failed because the direct local server had
no agent signing key. That owned fixture was removed. The retry uses an
ephemeral key in its isolated process environment.
- Owned fixtures were deleted, the local runtime exited normally, and
the disposable databases were dropped. Shared services remain running.
- No production deployment or npm publication is part of this PR.

## Risks

- Known deadlines now trigger a scan between heartbeat ticks. Existing
atomic claims, suppression checks, budgets, and execution rules still
decide whether work runs.
- Direct database writers rely on the heartbeat recovery scan. Overdue
blocked work also retains that recovery interval to avoid a tight retry
loop.
- This is not a hard real-time guarantee. Provider startup, queue load,
and other synchronous work can still delay agent execution.
- No database migration or API schema change. Revert this commit to
restore interval-only dispatch.

DottaandPaperclip ce024457f3 perf(server): wake email work from commits and deadlines (#15750)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Email connects agent tasks to durable incoming and outgoing
messages.
> - The email worker scans the database every second, even with no
inboxes.
> - These queries prevent idle database connections from closing.
> - This pull request wakes email work from committed writes and known
deadlines.
> - Empty email installations stop polling. Existing delivery and
catch-up guarantees remain.

## Linked Issues or Issue Description

Refs #15625. Related standby work: #15314.

**What existing behavior does this improve?**

The AgentMail background worker and its database traffic when idle.

**Current behavior**

Every instance queries active email endpoints each second. Active
inboxes also scan delivery queues each second even when no work is due.

**Proposed behavior**

Scan once at startup. Wake after endpoint and queue transactions settle.
Restore the next retry or catch-up deadline from existing rows. An
instance with no active inboxes has no recurring email queries or timer.

**Reason and benefit**

Thousands of empty instances should not keep their databases awake to
discover that email is still unconfigured.

## What Changed

- Use the shared transaction-aware coordinator for email work, including
changes made by separate service objects on the same database owner.
- Signal endpoint activation and control changes, incoming events, and
outgoing sends inside their transactions.
- Add an optional deadline to the coordinator. Email uses persisted
retry times, mailbox catch-up times, and socket reconnect times. Only
the first pending send in each conversation determines its send
deadline.
- Preserve startup recovery, lease fences, idempotency, standby
suppression, idle drain, and shutdown.
- Update the sleep inventory and add quiet-idle, commit, activation,
retry, and lifecycle tests.

## Verification

- Focused coordinator, email idle, and warm standby tests: 20 passed
locally.
- Database-backed email integration suite: 41 passed locally with real
PostgreSQL and a simulated AgentMail provider.
- After review, the updated delayed-reply regression passed separately:
1 selected test passed, 40 intentionally filtered out. It verifies no
scans before the first reply deadline and delivery of both replies in
order.
- `pnpm -r typecheck` and `pnpm build` passed locally.
- The local `pnpm test:run` was interrupted after its checkout was
removed externally. Completed local checks above are preserved. The
[final-commit hosted CI
matrix](https://github.com/paperclipai/paperclip/actions/runs/37997072212)
passed: 54 successful checks, 2 expected Storybook skips, no failures.
It includes the full general and serialized test matrix, runner checks,
browser tests, build, typecheck, and canary packaging.
- Greptile: 5/5 on `ec98f3b86ee476d75e0edf3366b357377ea09d69`, with no
actionable findings.

## Risks

- New email producers must register work inside their write transaction.
No new tables or migrations are required.
- Signals are local to one database owner and its dedicated pools.
Independent processes and direct SQL do not emit them. Startup recovers
existing work; configured inboxes also retain their recovery deadline.
- Active inboxes still catch up each minute. WebSocket mode still renews
its lease every 20 seconds. This change does not provide external waking
or make active sockets sleep.
- Provider calls were simulated in tests. No live email was sent.

DottaandPaperclip 835a022936 perf(server): wake delivery queues from transaction-aware work signals (#15625)
## Thinking Path

> - Paperclip manages AI-agent work and its delivery to users and
agents.
> - Five delivery queues scan the database even when empty.
> - Each queue already has durable rows; empty polling wastes idle
hosting capacity.
> - Producers can register intent inside their existing database
transaction.
> - Central transaction tracking can wake consumers after the outer
commit without extra caller wrappers.
> - A lost response needs reconciliation against PostgreSQL before an
empty queue is safe to leave idle.
> - This change uses one scheduler for outstanding work and lets
settled, empty queues go quiet.

## Linked Issues or Issue Description

Supersedes the closed #15614. Related idle-safety work: #15522 and
#15599.

**What existing behavior does this improve?**

Delivery scheduling for feedback exports, chat completions, connection
continuations, question answers, and tool-action receipts.

**Current behavior**

Feedback scans every five seconds. Four delivery queues scan on the
heartbeat interval, normally 30 seconds. Startup and some event paths
also scan them.

**Proposed behavior**

Each producer awaits one intent registration before its queue write. The
existing `createDb` transaction boundary tracks nested savepoints and
wakes the consumer after outer settlement. Startup scans restore durable
work. Pending rows, failures, and unresolved transactions retain retry
deadlines. Empty, settled queues have no timer or recurring scan.

**Reason and benefit**

Normal delivery starts after commit. Central tracking removes
caller-specific post-commit plumbing. PostgreSQL transaction status
resolves lost responses without new tables or a permanent uncertainty
latch.

**Breaking changes**

No API or schema changes. The notification scope is one DB owner and its
dedicated child pools. Direct SQL, separate roots, and other processes
require an explicit wake/recovery integration. This path requires
PostgreSQL 14+ transaction-information functions; embedded PostgreSQL
uses 18.

## What Changed

- Add one named-deadline scheduler and app-owned coordinator for five
existing queues.
- Instrument `createDb().transaction()` centrally, including nested
savepoints. Dedicated child connections share their owner's signal
scope.
- Register work before the five queue insert paths. The first
registration obtains the outer XID; unrelated transactions issue no
extra SQL. Tool receipt insertion gains a small transaction around its
existing insert.
- Query `pg_xact_status` only for rejected, tracked transactions. Probe
before scanning the queue. Retain the idle hold while PostgreSQL still
reports an in-progress transaction or the probe fails. Release it after
settlement and reconciliation.
- Remove unconditional delivery recovery scans and caller-specific
completion post-commit actions. Retain the existing task-scoped
completion activity fast path and durable claims.
- Coalesce wakes without postponing an earlier deadline. Retry
outstanding rows and failures; suppress dispatch during idle drain while
allowing transaction and queue reconciliation; suppress both during warm
standby. Cancel deadlines and await active delivery sweeps on shutdown.
- Serialize feedback flushes. Vote routes return after saving. Uploads
have a 30-second deadline and shutdown cancellation; unfinished exports
remain recoverable.
- Document the writer contract and update the dated sleep inventory.

## Verification

- Final head: `a4609956841107ad60c4cb50fe2acb05636b1363`.
- Passed: all final-head hosted checks, with 54 successes and two
intentional skips. The full test matrix, typecheck, build, canary, and
aggregate verification passed in [run
37940948440](https://github.com/paperclipai/paperclip/actions/runs/37940948440).
- Passed: Greptile 5/5 on the same head, with a successful check run and
zero unresolved review threads. The branch is mergeable.
- Passed locally after the final rebase: 50 coordinator, scheduler, and
startup tests; server typecheck; server build.
- Passed locally before the final import-only rebase: repo-wide
typecheck and build; 237 PostgreSQL producer/delivery and database
signal tests; feedback, native-question, and idle-safety regression
tests.
- Real PostgreSQL tests hold transactions open after an injected client
response loss, then commit or abort. They verify that an empty scan
cannot clear an in-progress transaction. Another test terminates a real
backend and verifies recovery without replay.
- Coordinator tests cover an hour with no empty-queue timers,
pending/error retries, worker replacement, concurrent writes,
earliest-deadline preservation, rollback during idle drain, committed
work during drain, standby, and shutdown.
- Local `pnpm test:run` was started and stopped after embedded
PostgreSQL startup failures appeared. It did not finish and is not
reported as a pass. Later local database reruns had skipped suites;
those skips are not claimed as verification. The earlier PostgreSQL
tests did execute and pass, and the final hosted full matrix passed.

## Risks

- One XID query is added per transaction that registers delivery work.
Nested transactions share that ID. Registration must be awaited before
writing; new enqueue paths must follow this contract.
- Work signals are local to a DB owner and its dedicated child pools.
Independent roots, direct SQL, or other processes are not observed.
Startup scans recover already committed rows, but do not fence late
transactions from a previous process. Cross-process ownership and
database failover require separate work.
- A database outage or genuinely unresolved transaction keeps an idle
hold until status can be reconciled. No timer clears uncertainty by
assumption.
- These changes remove five empty polling loops. They do not implement
whole-instance sleep, database teardown, or an external waker. The
earliest deadline covers only the registered queues.
- Waiting tool reviews retain their existing retry cadence until their
receipts can be delivered.
- Feedback vote responses no longer wait for the remote upload. Sharing
consent and the saved vote response are unchanged.
- Real hosting-provider sleep and cost savings have not been measured.
