DottaandPaperclip b1efd65edc fix: continue interrupted task conversations with bounded retries (#13237)
## Thinking Path

> - Paperclip manages AI agents and their tasks.
> - A task can outlive a provider process or a server restart.
> - Legacy recovery treated unknown tool outcomes as a permanent
execution hold.
> - That hold could also reject a later user message.
> - A conversation turn can use prior history without replaying prior
tool calls.
> - This pull request lets supported conversation adapters continue
within the existing retry budget.
> - Users can send a new message after automatic attempts stop.

## Linked Issues or Issue Description

**What happened?**

A server restart could interrupt a local ACP run and leave its task
behind a permanent recovery hold. A later user message could be
cancelled before the provider answered. The immediate recovery path
could also create a successor outside the durable failure counter.

**Expected behavior**

Continue with a bounded new conversation turn. Preserve a compatible
provider session or use full task context when it is unavailable. Do not
replay recorded tools. When automatic attempts stop, allow a new user
request through the normal execution gates.

**Steps to reproduce**

1. Start a task with a local conversation adapter.
2. Restart the server while the provider is working.
3. Let the previous run become interrupted.
4. Send a follow-up message and observe the recovery hold on the old
behavior.

Related work: Refs #13075 for durable task recovery. Refs #12946 for
retry-limit and checkout-lock handling. This change routes conversation
recovery through the existing bounded scheduler.

## What Changed

- Mark supported local conversation failures for continuation. Keep
native-runner and non-conversation recovery rules.
- Carry an interruption notice into the next turn. Retain stopped ACP
session history even when a write outcome is unknown.
- Clear unavailable ACP sessions so the next bounded attempt can use
full task context.
- Route immediate failure recovery through the same durable scheduler as
process-loss recovery. Release only the predecessor checkout when its
retry takes ownership.
- Retire obsolete conversation holds using immutable run evidence, in
bounded batches with an activity record. Preserve outcome evidence and
do not wake historical tasks.
- Block actual admission and Resume while a predecessor process or
environment lease is still active. Keep the original interruption notice
after a rejected wake. Preserve the upstream blocked-wake waiting
contract: bounded retry planning can happen during cleanup, while
deferred messages and execution remain gated.
- Add subprocess and database regression tests. Update the execution
contract.
- Add the current thread-status field to the native recovery provider
fixture so its damaged-journal test reaches the intended boundary.
Tolerate an already-exited fixture process during test cleanup while
still asserting both processes terminate.

## Verification

- Workspace typecheck passed: `pnpm -r typecheck`.
- Build passed: `pnpm build`.
- Module boundaries passed: `pnpm check:module-boundaries`.
- Focused tests passed: 293 recovery/session/dispatch tests, 66 retry
and response-gate tests, and 37 native-session tests. Some suites
overlap.
- Tests cover interrupted writes, missing sessions, concurrent retries,
restart persistence, pending questions and approvals, execution gates,
and historical holds.
- Built the Rust test executables with `pnpm --filter
@paperclipai/paperclip-runner build:rust` for native-runner
verification.
- Full Vitest coverage verified locally using the repository’s general
and serialized shards, with focused reruns for failures and files not
reached after a shard stopped. The ownership-gate regression is fixed
and the complete affected server shard passes (1,390 tests). Local
parallel runs also hit temporary-directory, resource, and timing
failures; those suites pass with canonical temporary paths and
sequential reruns. No test timeouts were increased.
- Final merged-branch regression run: 577 tests pass across process
recovery, retry scheduling, liveness, durable chat, wake-queue
application/adapter, dispatch, continuation, native sessions, and task
chat. Earlier focused verification also passed 19 native control tests.
Token gates and whitespace validation pass.
- Browser verification passed all three ACP Stop/continue/pause
scenarios, including a rerun after merging the upstream waiting
behavior: `PAPERCLIP_E2E_PORT=3397 pnpm test:e2e
tests/e2e/acp-stop-continuation.spec.ts`. The interrupted-write case
verifies that follow-up completes without a repeated write.

- Final-head [CI run
34625037394](https://github.com/paperclipai/paperclip/actions/runs/34625037394)
passed on `06ac4bd9d150f8b209a96e5fd609c696958794a0`: all 31 reported
checks are green, including server/workspace suites, all browser shards,
native runner verification, build, typecheck, release dry run, and
aggregate gates. The two conditional Storybook checks were skipped.
Greptile reviewed this exact commit at 5/5; all review threads are
resolved.

## Risks

- A new model turn can choose to repeat an action. Paperclip does not
replay recorded tool calls and does not certify unknown action outcomes.
- Conversation adapters now stop after their retry budget instead of
requiring action reconciliation. Explicit Stop, pause, dependency,
approval, budget, and ownership gates remain in force.
- No schema migration or dependency changes. Historical holds are folded
without changing task status or waking work.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, repository tools, code
execution, and test execution. The session does not expose a more
specific model build ID or context-window size.
