Design exercise: Automated Debugging & Remediation
Failure reproduction, hypothesis generation, telemetry, fault localization, minimal patches, validation, rollback, and learning. Implement designOutline() returning non-empty values for: reproduction, faultLocalization, patchVerification. Each value must name a concrete mechanism or decision.
The mechanism
Automated remediation should reproduce first, narrow the causal surface, make the smallest patch, verify the original failure and nearby behavior, then preserve evidence.
Expected evidence
A design outline with reproduction, faultLocalization, patchVerification plus an explicit failure mode or trade-off.

Hints when you need them
- Name the failure mode before selecting the mechanism.
