In buildDeterministic rules run first and cost nothing. Titles, versions, casing, featuring conventions, explicit flags, language and script consistency, identifier validity — checked against a published catalogue rather than a reviewer's memory.
- A 112-rule catalogue drawn from the store style guides that actually reject releases

- Severity per rule, so a warning does not block what a failure should
- Deterministic checks run before anything expensive is called
