DottaandPaperclip e3fb4bc73a fix(native): recover saved listener startup failures (#19479)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Native recovery must preserve saved work and respect current task
authority.
> - A closed local API listener can stop startup before a provider
starts.
> - #19462 gives new failures a bounded bootstrap retry.
> - Older saved failures still have a generic terminal code and a
recovery hold.
> - This pull request verifies the old producer outcome and uses the
existing safe replacement path.
> - Eligible tasks continue once. Unknown provider outcomes and user
holds remain blocked.

## Linked Issues or Issue Description

Refs: #19462

**What happened?**

A restart can leave an old listener startup failure in
`terminal_failure` with `native_session_interrupted`. Startup recovery
does not claim it after #19462. A completed file recovery can also
retain its no-replay hold.

**Expected behavior**

Continue automatically when durable records prove that no provider
started, the source stopped, and the current files were saved. Keep the
existing attempt budget and normal admission checks.

**Steps to reproduce**

1. Close the actual API listener after a fresh native coordinator claim.
2. Persist the old executor's generic failure. Save the workspace and
confirm source termination.
3. Restart recovery. The baseline schedules no successor. The repair
schedules one successor after all receipts pass.

**Paperclip version or commit**

Baseline: `0252421d5c`. Old failure producer: `2f35eb1080`.

**Deployment mode**

Built from source. Local macOS arm64, Node 26.4.0, real embedded
PostgreSQL, independent filesystem execution. No external AI service is
used by the controlled acceptance.

## What Changed

- Recognize the exact saved local-listener guard through one proof
predicate shared by discovery and the locked transaction.
- Require a fresh first attempt, matching execution bindings, no prior
provider lineage, no provider events or tool calls, no checkpoint or
admission receipt, and no cancellation.
- Reuse current snapshot, exact stop, source block, attempt budget, and
successor idempotency checks.
- Wait for completed source file-recovery receipts. Retire only that
same source's verified preservation hold in the successor transaction.
- Bound discovery to 100 candidates per pass, keep completed history
quiet, and wake through existing transactional producer notifications.
- Retain retries after transient database and final ownership-proof
errors; advance the bounded cursor and force a rescan so a failing page
cannot hide later work.
- Let only the replacement duty discharge a proved-empty notification
during drain through its existing read-only readiness check, once per
notification generation. Keep real work and concurrent changes
outstanding without running replacement during drain.
- Wake replacement at canonical local-stop proof writes and the existing
dispatch eligibility boundary; these hints grant no new execution
authority.
- Add database regressions, scheduler quietness checks, real controller
handoff coverage, and an opt-in controlled Runner continuation.

## Verification

Final production head: `0df41b2fef2644195d1224d36984af3827da3e3b`.

Local environment: macOS arm64, Node 26.4.0, TypeScript 7.0.2, Vitest
5.0.3, frozen-lockfile dependencies. Tests execute freshly;
`--fsModuleCache` reuses only content-validated module transforms.

- Native safe replacement: 62/62 PASS on isolated PostgreSQL 17 (63.18
seconds), including clean per-suite database disposal. All 62 assertions
also passed on embedded PostgreSQL 18 beta, but its Darwin cleanup hook
timed out; that invocation is not counted as a pass. Docker's disk was
full, so the disposable PostgreSQL 17 data used a size-limited RAM
mount, with no host mounts. The owned container was removed afterward.
- Actual stopped-process producer suite: 31/31 PASS. A real exited child
produces the stop receipt, and its replacement notification settles only
after the outer transaction commits.
- Workspace and separate-process drain regressions: 33/33 PASS (75.90
seconds).
- Shared coordinator and execution-control lifecycle checks: 39/39 PASS
(16.43 seconds). Pending work, concurrent changes, cold startup,
shutdown, and passive drain boundaries remain covered.
- Actual suppressed Cloud routine/drain workflow: PASS (34.64 seconds),
using the unchanged test and timeouts. Its matching local RED reproduced
CI's 462-query, zero-pending-query, one-idle-hold timeout after an
admitted write committed during drain (69.46 seconds).
- Actual historical controller handoff: PASS (48.40 seconds). A separate
controller loads the original executor from `2f35eb1080`, writes its
generic listener failure, and exits. Recovery at the final head admits
exactly one successor. The real Rust Runner and controlled Codex process
complete governed `paperclip_finish`; attempt two commits and the saved
file remains intact. Only the child loads the old artifact, and both
isolated artifacts are restored afterward. Rust source subtree
`77961b70f177ec3c38d11abcaec92fd3d0e96ec0` matches the built binary. No
external AI service is used.
- Seven corrected existing fixtures pass: transactional stop-proof calls
(5 cases) and notification inventory (2 cases). Their earlier CI
failures exposed fixture calls outside the documented transaction and an
outdated expected queue set.
- Server typecheck: PASS.

Red/green proofs also cover the original saved failure on baseline
`0252421d5c` (zero successors instead of one), held-history quietness,
bounded forward scanning through 100 parked rows and concurrent wakes,
real snapshot/cleanup producer notifications, actual issue-row lock
timeout, and task/history eligibility notifications. An obsolete
prior-run question can be skipped to request another proof check; actual
skip while the task is paused or the source owns provider tool activity
schedules no successor.

The failed-page regression starts with 25 persistent verifier errors and
a healthy candidate 26. Baseline RED repeats the first page. Repair
GREEN advances the healthy candidate, revisits the original failures
after their fault clears, creates all 26 successors exactly once, and
becomes quiet.

Greptile is SUCCESS, 5/5 on the exact final head (2026-11-06 17:09:21
UTC). Final-head CI is GREEN: 56 successful checks, three intentional
skips, one neutral result, and no pending or failing checks. [Attempt
two and
results](https://github.com/paperclipai/paperclip/actions/runs/42258352876/attempts/2)
include passing build, typecheck, Rust, native server, package, browser
E2E, serialized server, general server/chat tests, and final
verification. Five jobs in the first attempt were interrupted together
at 17:13:12 UTC; the native-server log records an explicit runner
shutdown signal. The single infrastructure retry reran only those five
jobs and dependent verification, preserving the 49 successful checks on
the unchanged head. No timeout was weakened, and setup failures or
interrupted invocations are not counted as passes.

Focused commands from the repository root:

```sh
./server/node_modules/.bin/vitest run --project @paperclipai/server server/src/services/remote-workspaces.integration.test.ts server/src/services/native-runtime/native-runner-restart-preparation.integration.test.ts -t 'native safe-replacement decision|reconciles the drained remote backend' --fsModuleCache --reporter=dot
./server/node_modules/.bin/vitest run --project @paperclipai/server server/src/__tests__/execution-control-work.test.ts server/src/__tests__/delivery-work-coordinator.test.ts -t 'execution-control lifecycle|work coordinator' --fsModuleCache --reporter=dot
node node_modules/typescript/bin/tsc -p server/tsconfig.json --noEmit --pretty false
```

The historical acceptance sets `PAPERCLIP_TEST_HISTORICAL_LISTENER=1`
and uses an original-executor child artifact with a `try/finally`
restore. Normal regressions require no Rust binary.

## Risks

- Compatibility is deliberately limited to positively proved fresh
remote startup failures. Other old ambiguous failures remain held.
- Existing provider work, a changed task block, incomplete preservation,
or revoked authority must prevent execution. Normal retry admission
remains in control.
- This PR does not deploy the change or mutate a hosted task. Hosted
recovery still requires the repaired revision and all current proof
gates.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, tool use, and code
execution. The exact backend model identifier and context window are not
exposed in this session.

DottaandPaperclip 505e1a5582 feat(cases): add persistent workflows with same-task agent handoffs (#16959)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - An agent workflow needs persistent facts and a safe way to transfer
work.
> - Creating a task for each phase splits the objective, discussion,
workspace, and review policy.
> - A case can retain the facts while one primary task moves between
agents.
> - Transfers must survive process failure and preserve private access,
budgets, and completion gates.
> - This pull request adds durable case handoffs, native case tools, and
read-only case pages.
> - Prompts describe the workflow. Existing task controls decide when
work can run and finish.

## Linked Issues or Issue Description

**Problem or motivation**

Prompt-driven agent teams need a persistent record that can move through
triage, implementation, verification, and correction. Ordinary
reassignment does not provide a durable instruction, safe release
barrier, or recoverable delivery receipt for an agent handing off its
own running task.

**Proposed solution**

Extend standalone cases with one primary task, a descriptive phase,
retained access sources, and a handoff ledger. Apply assignments after
source execution and workspace settlement. Deliver each transfer through
the existing durable wake queue. Provide `create_case`, `read_case`,
`update_case`, and `handoff_case` in the native runner. Creation
requires kickoff and explicit workflow text. An explicit handoff to
`done` closes the case when normal task completion is accepted.

**Alternatives considered**

Do not add a workflow engine, filesystem queue, configured state graph,
or one task per phase. The workflow document combines transition prose
with an optional Mermaid `stateDiagram-v2` map. The server does not
execute the diagram. The Pipelines experiment removed on master stays
removed.

**Roadmap alignment**

This extends Agent Reviews and Approvals, Enforced Outcomes, Bounded Run
Recovery, and Activity Log attribution. Existing approval, review,
budget, privacy, workspace, and responsible-user rules remain
authoritative.

Related work: [ordinary handoff wake
recovery](https://github.com/paperclipai/paperclip/pull/15019). This
feature adds a separate persisted case-handoff receipt and release
barrier.

## What Changed

- Add case routing fields, retained access sources, durable handoff
history, delivery leases, and replay-safe migrations.
- Keep the same primary task across agent phases. Preserve each
returning agent's own session and the task's workspace.
- Fence outgoing mutations, wait for provider and workspace release, and
recover delivery without duplicate task comments or runs. Recheck
current assignment permissions as the original caller before applying a
delayed transfer. Scope a run Stop to that run’s own handoff intents, so
repeated old Stop requests preserve newer work. Cancelling terminal
intent without a source run also requires fenced current task ownership,
including native retries and preparation with an old checkout. For Cloud
callers, revalidate current stack membership with an uncached Cloud RPC
and derive owner elevation from the current managed setting.
- Keep case reads, documents, assets, Audit, and live events inside
retained task/project permissions.
- Add native case creation/read/update/handoff tools. Store required
workflow text and initial documents on the first task. Page oversized
case facts and referenced document bodies through the dedicated tool
with bounded UTF-8 JSON, current routing versions, snapshot conflicts,
and current source authorization on every page.
- Add read-only case lists and detail pages, task-style list controls,
compact dotted field tables, linked handoff tasks, and case filters in
Audit.
- Add native/legacy integration tests, migration/restart tests, browser
coverage, and bounded live receipt fixtures. Extend the trusted sandbox
condition to cover the new subscription fixture profile.
- Hide obsolete paused-agent warnings on completed or cancelled task
threads.
- Synchronize the company-switch settings test with React effects after
a CI failure. Preserve its security assertions and production remount
behavior.

## Verification

The branch directly includes master `9ef434fe79`. The required `ci /
verify` and `ci / e2e` gates pass on head `765fccd67c`. [Current-head
CI](https://github.com/paperclipai/paperclip/actions/runs/39464348614)
passes typecheck, build, tests, and all eight browser shards. Security
checks pass. [Greptile gives this exact head
5/5](https://github.com/paperclipai/paperclip/pull/16959#issuecomment-6291156549),
with no unresolved review threads. The optional Paperclip Review check
remains queued because its assigned agent is paused. It is not a
required branch check. No check result was overridden.

Local workspace typecheck and build pass after the master merge, along
with database migration checks, token gates, map checks, Storybook
catalog checks, and the Copilot profile identity check. Standard builds
refresh Runner vendor output. Focused checks pass 2,008
API/paging/context tests and 7 strict case protocol tests. The final
commit changes one test fixture only; its ten tests, UI typecheck, and
token gates pass. No production source changed in that commit.

On current head `765fccd67c`, all **194 critical workflow tests**
executed and passed with no skipped tests in those files:

- 38 Stop/ownership tests, including board completion intent, native
retries, stale Stop, and preparation with an old checkout.
- 2 actual legacy process/HTTP handoff tests, including scratch failure,
a closed-stdio child that continues writing, and recovery through a
fresh worker after the process group stops.
- 5 migration tests, including SQL column metadata, preserved null
authority context, and all six prior-numbering receipts.
- 3 process-settlement and 5 scratch tests.
- 88 handoff-service, 18 heartbeat handoff, and 21 native case-tool
integration tests.
- 7 bounded case/document-read projection tests and 7 strict
protocol-contract tests.

The current CI checkout was `fed65d49`, merging `765fccd67c` into master
`9ef434fe79`. Its new document regressions reconstruct exact
Unicode/escaped bodies and revisions through real native authority and
authenticated HTTP with generic API tools disabled. They cover
case-owned, primary-task, and linked-task documents; routing on every
page; stale document snapshots; access loss and unlinking;
unrelated/foreign/private sources; system documents; and quarantined
content. Active-task document tools retain their existing behavior.
These are current-head test results from the first CI attempt; the
browser-only retry did not rerun these suites.

The full `64fdd3403f` CI failed one separate settings test: after a
company switch, it observed an unsettled API-key draft. The production
component and test were unchanged from prior green source. Production
switches remount both keyed settings layers; the test directly reused an
unkeyed view and used a timer tick instead of waiting for React effects.
The final commit replaces that fixture synchronization with React `act`.
The exact secret-clearing assertions and all timeouts remain unchanged.
The original assertion failure remains recorded; no unchanged retry was
used. The narrow unchanged baseline and fixed fixture each pass 10
tests.

The upstream result-paging merge preserves case capture namespaces and
current asset privacy. Its API integration suite executed 39 of 41 tests
successfully, with two skipped; the optional assigned-result PRP
integration test was skipped. Neither skipped suite is counted in the
194 critical tests or as live provider proof.

All 361 upstream migration entries and SQL bodies remain unchanged. Six
case migrations follow master as 0363–0368 with identical SQL hashes.
Official Drizzle generators produced the combined metadata and five
retained snapshots. Generation reports no schema changes, and the
snapshot drift test passes. The earlier `ce361ae5d0` CI passed on
attempt 1, including its then-current 179 critical tests. Fresh review
later identified unusable document references with generic API tools
disabled; the bounded document reads and ten additional authenticated
HTTP tests address that finding.

The full local `pnpm test:run` attempt was cancelled after this Mac
exhausted PostgreSQL semaphore capacity; it is **not** counted as a
pass. Later database attempts also stopped before assertions or skipped,
including one sandbox socket denial. Two original stale-Stop regressions
did reproduce the bug against the old source. A REST serialization
assertion passed after two preserved database-startup failures. No test
timeout was increased. All 194 assertions listed above executed and
passed in current-head CI. The complete 385-file, 3,963-test UI shard
also passed after the fixture repair.

A configured-provider receipt workflow passed 13 backend checks across
triage → implementation → verification → correction → done, using one
task and four work runs. The saved receipt is revision 2 with total 6
USD; case and task both closed. The original canonical attempt remains
failed because its browser assertion confused the terminal destination
with completed-task tooltips. The corrected full browser verifier passed
on the same retained database and original runs, with no additional
provider calls. The last clean-build browser readback is on
`6a86c54a53`; later changes affect recovery, authorization, bounded
reads, and settlement. Accounted work cost is a $1.010574 rate-card
estimate; provider billing and setup-probe usage are unavailable.

Copilot profile 49 passed the unchanged seven-fixture private protocol
pack (46/46 checks, no retries) and the product file-edit canary after
master's completion-replay change. All 60 bound implementation hashes
remain unchanged on the current source. Historical profile-47/48
identities and results remain intact. See the [profile-49 compatibility
record](https://github.com/paperclipai/paperclip/blob/codex/persistent-case-handoffs/doc/plans/2026-10-20-copilot-completion-recovery-compatibility-v49.json).
This is bounded compatibility evidence, not a fresh full matrix,
installed-package product test, or Daytona rollout.

Preserved CI failures and retries:

- On `20662930ac`, Slack managed setup failed a five-second success
assertion after reload. Its test/application path was unchanged from a
prior green head. One unchanged-source retry passed all 25 tests in that
shard; no source or timeout changed.
- On `9402b4f17a`, two CI workers received shutdown signals at 15:24:19
UTC. Neither log had an assertion failure before interruption. One
unchanged-source retry of each passed all Runner static checks and all
32 tests in browser shard 6; both aggregates passed. The next head,
`7b4374edaf`, passed all CI without retries.
- On `295f289b5a`, serialized shard 9 timed out during its first
device-login test, then the next test found an active login lease.
Direct login/test paths were unchanged from a prior green head. Cold
import plus a timed-out async body using the next test's mutable
actor/store is the supported fixture-race explanation; no request trace
proves that sequence. The original failure remains recorded. One
unchanged-source retry passed all 294 tests in 19 files, including all
41 device-login tests. No login source or timeout changed. The
subsequent `ce361ae5d0` CI passed without retries.
- On `64fdd3403f`, one company-switch settings assertion observed an
unsettled draft. The final test-only commit uses React `act` without
changing assertions, timeouts, or production code. On `765fccd67c`, all
ten settings tests and the complete 385-file, 3,963-test UI shard
passed.
- On `765fccd67c`, browser shard 3 completed the split-handoff
assertions, then cleanup received HTTP 500 from run cancellation after a
one-second PostgreSQL row-lock timeout. The extra chat run was reporting
completed work while teardown began. Cleanup stopped before restoring a
global experiment flag, causing a later assertion to fail. Relevant
production and test paths are unchanged from an earlier green commit.
Stop's lock order is consistent, and no nested self-lock was found; the
exact PostgreSQL blocker was not recorded. One unchanged-shard retry
passed. The original failure, trace, and downstream flag failure remain
recorded. No Stop implementation, cleanup assertion, or timeout changed.
The retry supports intermittent cleanup contention; it does not identify
the original blocking transaction.


## Risks

- Local process transfers require host-owned PID/group absence. Missing
or uncertain termination evidence keeps delivery pending, independently
of scratch setup.
- Handoff admission and task cancellation share execution ownership. New
regression tests cover temporary holds, late source writes, and
uncertain provider termination.
- Retained private sources use an intersection of existing permissions.
This intentionally fails closed when a source is missing or an existing
task cannot preserve that boundary.
- Migrations add tables and indexes. They preserve master history and
can replay over prior feature installs. Migration 0368 adds nullable
internal authorization provenance with no default or authority backfill.
Historical transfers still awaiting release without this context fail
closed; an operator must cancel them and request a new handoff.
- Delayed Cloud handoffs depend on the current Cloud membership RPC. An
unavailable, ambiguous, expired, or mismatched response holds the
handoff for retry; it does not reuse cached authority or grant access.
- Bounded reads reload and reauthorize the selected projection per page.
Underlying work grows with the data size and number of pages. Changed
data or routing requires restarting from offset zero without the old
snapshot.
- Phase names and workflow diagrams remain advisory. They do not satisfy
review or approval gates.
- This is a large, cross-cutting PR. The maintainer requested one PR for
the whole feature; the commits separate data, runtime, UI, and
qualification work.

## Model Used

OpenAI Codex, GPT-6 family, with tool use, code execution, and delegated
code review. The exact deployment model ID and context-window size were
not exposed in the session. Live fixture agents used the explicitly
configured provider model recorded in their test evidence.
