📝 WalkthroughWalkthroughThe Inspect adapter now forwards configured model arguments, reads subprocess timeouts from ChangesInspect execution configuration
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change adds configurable evaluation timeouts, but a configured timeout can currently be passed in the wrong type and subprocess failures can be replaced by an unrelated runtime error. This can make benchmarks fail and obscure the root cause, so the PR is not merge-ready until these two execution-path issues are fixed.

Convert INSPECT_EVAL_TIMEOUT to a numeric timeout before calling subprocess.run.
When INSPECT_EVAL_TIMEOUT is set, env.get() returns a string. subprocess.run raises TypeError for a string timeout, and the existing handler does not catch it. Parse and validate the value before the call.

Re-raise subprocess failures after logging them.
When subprocess.run raises, result remains undefined. The later access raises UnboundLocalError and hides the original exception. Add raise after logging.exception(...).
