Missing prerequisites: security-easy-secret-redaction-logs

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. Minimize blast radius, make the result auditable, and explain the tradeoff you chose. 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.
