Editorial rules are locale- and channel-aware executable policy
Machine-readable profiles govern interface language while explicit exceptions preserve local ownership.
Guidance
Load locale, channel, and lexicon profiles before writing; lint only deterministic rules and show rationale for judgment.
Do
- Give every error-level rule accepted and rejected fixtures
- Scope exceptions by reason, approver, and expiry
Do not
- Apply US-English conventions globally
- Use opaque AI voice scores as enforcement
Verification contract
