Target time
24m
Incident logs accidentally included API keys from failed webhook requests. You are working inside a secure engineering review room, and the arena only clears when the result is safe, deterministic, and explainable.
Learning objective
Learn to apply credential detection, structured logging, redaction boundaries, and safe observability in a secure engineering review room while explaining the invariant, safety constraints, and hidden edge cases.
Mission order
Log entries include headers, bodies, stack traces, request IDs, and nested JSON payloads. Implement the direct solution first, then document the one edge case that can break it. Submit the solution plus enough reasoning to pass hidden edge cases.Visible checks
reproduces the reported failure
Expected: minimal failing case
adds a regression test
Expected: test fails before fix
Clear requirements
- Demonstrates credential detection, structured logging, redaction boundaries, and safe observability
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution

Test Results
Run the visible checks when your first pass is ready.
Clear Protocol
1Read the scenario and restate the expected output shape.
2Run visible checks before chasing hidden edge cases.
3Use Genie for one nudge if stuck, then explain the invariant.
4Submit only when the result is deterministic and safe.
