+## Non-negotiable interpretation
+
+Phase 8 automated checks proved prototype behavior, not production readiness or human comprehension. Participant testing, native linguistic review, CRM integration, consent, analytics approval, evidence approval, and several commercial decisions remain gates. A developer must not convert provisional copy into a public claim merely because it exists in a JSON file.

+The validator checks required artifacts, JSON syntax, locale key parity, route coverage, token references, issue ownership, and manifest integrity.
