Version support

Apple format revisions, OpenARI package releases, C ABI, report schemas, policies, and trust-data generations have separate versions. The project does not assign Apple version numbers before the format defines them.

Future confirmed revisions can coexist in the engine. Detection selects an exact profile. Unknown versions and critical extensions cannot fall back to an older verifier. A supported profile may be disabled by policy after a security finding.

Consumers must check report-schema support and treat unknown decisions as unsupported. Cached results include the policy and trust-data context and must expire when that evidence becomes stale.

See the versioning contract.
