## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - The Paperclip Runner package manages live sessions and durable
command recovery
> - Capability live-session tests can fail when a turn-timeout rejection
has no handler
> - A resumed session can also stall when the durable control plane
rejects an indeterminate command result
> - These failures make valid tests fail or hide the turn that stalled
> - This pull request captures timeout rejections early and accepts
indeterminate recovered commands
> - The benefit is stable tests and clearer timeout failures after a
runner restart
## Linked Issues or Issue Description
**What happened?**
Capability live-session tests failed intermittently on loaded CI hosts.
A timer could reject a turn promise before the test attached its
assertion. A resumed session could also stall after a runner restart
because the durable control plane rejected the indeterminate command
status.
**Expected behavior**
The test must handle a timeout rejection at promise creation. The
durable control plane must accept an indeterminate recovered command and
allow the session to continue. A configured timeout must persist in the
checkpoint and identify the stalled turn.
**Steps to reproduce**
1. Run the capability live-session test file on a loaded host.
2. Create a turn promise with a timeout and delay before attaching its
assertion.
3. Resume a session after a runner restart with a journaled but
unconfirmed command.
4. Observe the unhandled rejection or the stalled resumed session.
**Paperclip version or commit**
Commit `ede642e57e22ea3fb0a73590fca8bcc994f1a47f` on `master`.
**Deployment mode**
Built from source.
**Installation method**
Built from source.
**Agent adapter(s) involved**
Not adapter-specific. The tests use the Paperclip Runner package.
**Database mode**
Not database-related.
**Additional context**
Pull request #12646 also updates durable recovery for indeterminate
command results. If it lands first, this pull request must retain the
compatible behavior without duplicate edits.
## What Changed
- Add a helper that captures a turn rejection before any await step.
- Update three live-session test sites to assert the captured rejection
value.
- Add a helper test that waits past the turn timeout before it asserts.
- Accept indeterminate as a terminal recovered-command status.
- Add tests for acceptance, duplicate absorption, and reload from
persisted state.
- Add an optional turnTimeoutMs value to resume and pin its checkpoint
behavior.
## Verification
- `npx vitest run src/live/live-session.test.ts` from
`packages/paperclip-runner`: 19 passed, 1 skipped.
- `npx vitest run src/control-plane/durable-prp-control-plane.test.ts`
from `packages/paperclip-runner`: 5 passed.
- The live-session file passed 10 of 10 runs with 30 competing workers
on a 32-core host.
- TypeScript reported five pre-existing errors in
`src/eval/workflow-harness.ts`.
- CI must run `pnpm --filter @paperclipai/paperclip-runner check:all`.
## Risks
The durable control plane now accepts one additional terminal recovery
status. The change affects only recovered command handling and
capability live-session tests. The main risk is overlap with pull
request #12646 if that pull request lands first.
## Model Used
OpenAI Codex, GPT-5, with tool use and code execution.
