Summary by CodeRabbit

• Improvements
  • Repeated requests for an AI-generated deployment risk summary can return more quickly by reusing a recent result.
  • When deployment risk information changes, a new summary is generated to reflect the updated context.

The service now caches successful AI risk summaries for 15 minutes. Cache keys use the deployment ID and a hash of sanitized risk context. Tests cover cache reuse and cache misses when risk data changes.

Changes: AI risk summary cache

Layer / File(s)	Summary
Cache lifecycle and validation central/deployment/service/service_impl.go, central/deployment/service/service.go, central/deployment/service/risk_ai_summary_test.go	The service initializes a 15-minute cache and checks it before querying Lightspeed. Successful responses are cached. Tests verify reuse for identical requests and a new query when risk data changes. They also check that cache keys differ when the deployment ID or risk context changes.

Estimated code review effort: 3 (Moderate) | ~15 minutes

Full details: Description check

Explanation

The description states the purpose: a 15-minute timed cache for LLM risk summaries in the risk deployment service, keyed by deploymentID plus a hash to avoid collisions between deployments. However, the template's required sections are not completed. The 'Description' section still reads 'change me!' and contains the unfilled template comment. The 'User-facing documentation' checkboxes are unchecked, with no CHANGELOG or documentation PR decision. The 'Testing and quality' checkboxes are unchecked, including the production-readiness and feature-flag gate. The 'Automated testing' checkboxes are unchecked, though the summary shows new unit tests were added. The 'How I validated my change' section still reads 'change me!' and gives no validation steps. The core intent is clear, but the description is largely incomplete against the template.

Resolution

1. Replace the 'change me!' placeholder in the Description section with a detailed explanation of the change. Include the cache TTL, the key format, and the reason for the hash-based key. 2) Answer the user-facing documentation items. Check CHANGELOG.md or mark the update as not needed. Link a documentation PR or mark it as not needed. 3) Complete the testing and quality items. State whether the change is GA or gated by a feature flag. Note the CI inspection status. 4) Mark the automated testing items that apply. The summary shows unit tests were added to risk_ai_summary_test.go, so mark 'added unit tests'. 5) Replace the 'How I validated my change' placeholder with the validation performed, such as the new unit tests and any manual checks. Explain any skipped testing.
