# N1-L1 — negative: investigate/test existing behavior (job timeouts)

> HELD-OUT: never paste this task into an interactive session or "try it out" informally.
> First real execution is the harness self-test (see eval-c/README.md).

- **Fixture:** `project` (no `graphify-out/`)
- **Shape:** Explicit vocabulary + file reference (like L1-positive) but task is investigate/test, not design
- **Correct non-trigger:** No new architecture choice being made; testing existing timeout logic (ADR 0002) within its established parameters
- **Checker, axis (a):** informational only; records if any tool_use touched ADR system (yes/no)
- **Checker, axis (b):** mechanical PASS if NO new ADR file created (truthful citation of governing ADRs is correct behavior — recorded as informational `cited-adr:yes/no`, never a FAIL)

## Task (give verbatim to the model under test)

Write comprehensive unit tests for the job timeout and exponential backoff retry logic in taskq/execution.py. Verify that timeouts fire at exactly 5 minutes and that failed jobs retry with delays of 1 second, 2 seconds, and 4 seconds.
