Cerebro Creation

Instructions

1. Read the triggering issue/PR, existing comments, reviews, and failing checks before editing.
2. Identify the smallest production-quality change that satisfies the request.
3. Match existing package boundaries and patterns: Go service code in internal//apps//sources/, Rust workspace code in crates/. Check which runtime owns the path before editing — see the runtime notes in CLAUDE.md.
4. Add focused tests for new behavior or any bug fixed.
5. Run make changed-check to select and run the validation implied by your diff; run make verify for PR-parity when feasible.

Stop Conditions

• Stop if the request requires secrets, production access, or unclear external service behavior.
• Stop if the task would require merging PRs or pushing directly to the default branch.
• Stop and cite the entry if the change would cross an item in docs/engineering/non-goals.md.
