Universal task completion, verification gate, and self-audit protocol. Use as the final gate before declaring any task complete, submitting a PR, or reporting completion to the user. Enforces the 5-Point Verification Gate (requirements traceability, static types, test suite execution, diff sanity, and negative boundary validation), assumption auditing, and strict evidence certification. Do not activate for pure read-only code exploration or exploratory brainstorming tasks where no code or state was modified (use project-analysis or answer directly), or for active in-progress failure diagnosis during implementation (use failure-recovery).
