ChangesExec readiness diagnostics
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change preserves Brev readiness diagnostics and attempt counts, but it may currently persist unbounded child output in CI artifacts or logs, and the timeout test does not prove that the final failed probe is retained. The PR is mergeable with explicit owner follow-up to sanitize diagnostics and strengthen the assertion. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Sanitize readiness output before persisting or logging it.
lastResult contains raw stdout and stderr. The code writes the full object to brev-exec-readiness-failure.json and includes the same output in the thrown error. A Brev failure can expose child output in the artifact and CI logs. Redact and size-limit the diagnostic before both sinks, or persist a sanitized summary.
As per path instructions, test/e2e/README.md requires that “evidence should be secret-free, bounded” and says to “avoid exposing raw child output in logs.”

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Make the timeout test distinguish the final probe.
Every failed probe returns "ssh unavailable", so the test passes if waitForExec stores the first failure instead of the last one. The rejection assertion also checks only the generic timeout prefix. Return distinct stderr values for successive probes, then assert that the artifact and thrown error contain the final value and the recorded attempt count.
As per path instructions, tests must prefer “observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions.”

Summary
Retains the final failed
brev execresult and attempt count when a staging workspace never becomes remotely executable. The previous run created and later removed the workspace, but discarded every readiness stderr message, leaving only a timeout.Related Issue
