 ## Constitution Alignment (Mandatory)
+*Refer to `.specify/memory/principles.md` for the canonical principle wording; list only the relevant numbers and compliance notes here.*
 List how this feature will comply with core principles:
 - Test‑First (P1): Failing unit tests in `tests/unit/test_<feature>.py` BEFORE implementation.
 - Explicit Configuration Boundaries (P2): New behavior exposed only via documented action inputs (list if any needed).
