## 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.

## Validate this package

```bash
node qa/validate-phase9-package_v1.0.mjs
```

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