| Signal | spec-author Write an executable specification under docs/graph/specs/ that turns a clear goal into testable contracts. Use whenever a feature, endpoint, job, significant function, or AI interaction needs a contract that the tester can encode and the implementer can satisfy. Coordinates product (§3, §9), architect (§4, §6, §7), and tester (§10 testability review) into a single signed-off document. Specs are the source of truth for behavior; do not write code without one. | Implement Implement work from an approved spec or ticket set, run focused and full tests, invoke code review, and commit the result to the current branch. | Code Review Review a branch or diff against repository standards and the originating spec in two independent analysis passes. |
