.offering_entry(offering, availability) ⇒ Object

Registry offerings are always published (enabled) — the old store's disabled-lane filter has no SSOT equivalent.

end

.policy_permits?(offering) ⇒ Boolean

§9.5 fail-closed model policy — same semantics as ModelCatalog.policy_permits?: a nonempty effective whitelist requires a case-insensitive substring match; a blacklist match always denies. The SSOT registry publishes the full provider catalog (policy is applied at selection time via SettingsState); the display surfaces apply it here so a denied model never appears in the API surface (compliance-by-absence invariant).

Returns:

  • (Boolean)

.snapshot_offerings(filters) ⇒ Object

D14: offerings are projected from the NEW Registry snapshot — the old Concurrent::Map lane store is no longer populated at runtime on the SSOT branch. Display only; selection reads the AvailabilityFact itself, never these projections.
