DottaandPaperclip 64895f187b fix(runner): clarify completion errors and restart test failures (#13682)
## Thinking Path

> - Paperclip manages work across persistent agent sessions.
> - The runner validates completion calls before accepting their
results.
> - Generic validation errors can leave the agent unable to repair a
rejected call.
> - Restart tests also exempted every later failure on an intentionally
interrupted run.
> - This change gives bounded schema feedback and limits the test
exemption to expected interruption outcomes.
> - Failures become easier to repair and diagnose without changing
authorization or task prompts.

## Linked Issues or Issue Description

Refs #13674 and #13676. Related environment and Agent Chat fixes landed
in #13677 and #13678. Those changes do not cover these diagnostics.

**What happened?**

A malformed completion call received a general field list without the
failed schema location. The everyday restart test hid later adapter
errors on an intentionally interrupted run until its deadline. A clean
pnpm install also broke the shutdown test because it resolved an
undeclared Playwright package.

**Expected behavior**

Return enough schema information to repair completion calls without
returning submitted values. Fail promptly on an unexpected recovery
error. Resolve the declared test package's CLI.

**Steps to reproduce**

Run the new completion-validation and everyday lifecycle regressions
against the parent commit. The new assertions fail there. Run the
shutdown test in a clean workspace installation.

**Paperclip version or commit**

Based on master c1f6c3310.

**Deployment mode**

Native runner and Runner E2E harness, local and Daytona.

## What Changed

- Add up to three schema locations and missing field names to rejected
completion-tool feedback. Limit the message to 512 bytes. Do not echo
input values or unknown input keys.
- Preserve generic errors for other or unauthorized tools.
- Exempt only expected cancellation, shutdown, and process-loss outcomes
in fault-injection tests. Apply the same rule while polling and grading.
- Fail promptly when persisted review timestamps prove the required
blocked-parent ordering was not exercised. Wait when separately fetched
snapshots lack that evidence. Keep the boundary requirement.
- Use the CLI export from the declared Playwright test dependency.
- Add red/green regressions and document the interruption rule.

## Verification

- 393 Runner E2E harness tests pass.
- 291 runner-core library tests pass.
- Harness typecheck and runner TypeScript build pass; Rust formatting
and git diff checks pass.
- The baseline completion regression and three lifecycle assertions
failed before the fix and pass after it.
- Fresh worker-setup rerun:
https://github.com/paperclipai/paperclip/actions/runs/35449301275 (7/8
passed). Mini completed the child review and both tasks, but did not
enter the blocked-parent-before-review ordering required by that case.
The new diagnostic identifies this unexercised boundary promptly; it
does not turn the case into a pass.
- Candidate Mini rerun:
https://github.com/paperclipai/paperclip/actions/runs/35449686308. The
recording has one rejected completion followed by success, compared with
12 validation errors in the baseline. The case still fails because it
does not hire the requested teammate, despite delivering a ZIP that
passes artifact checks. This is not a behavioral pass claim.
- Updated report:
https://pages.paperclip.ing/runner-e2e-operational-35444497313/investigation.html.
- All 55 PR checks are successful or skipped on 4d2c91869, including
repository typecheck, build, tests, native Runner checks, and Greptile
5/5. The reviewer withdrew the diagnostic finding after confirming the
conservative behavior avoids false rejection from non-atomic snapshots.
Local verification was limited to the affected harness and runner.

## Risks

Schema feedback must remain bounded and exclude submitted values.
Stricter fault grading can expose previously hidden failures. The
Daytona restart identity bug and remaining behavior failures are not
fixed here. Runtime authorization, completion validation, and production
prompts remain unchanged.

## Model Used

OpenAI GPT-6 via Codex, with repository inspection, code editing, and
test execution. The exact deployment identifier and context-window size
are not exposed in this session.
