feat(security): ADR-0056 D7 — app-declarable default profile (isDefault)#2070
Merged
Conversation
Add `isDefault` to PermissionSetSchema; the SecurityPlugin resolves the fallback permission set from an app-declared `isDefault` profile when no explicit fallbackPermissionSet is configured (else member_default — non-breaking). Foundation for SSO/JIT provisioning. Proven by showcase-default-profile (2/2): a signup governed by a custom default grants announcement but denies private_note (which member_default's wildcard would allow), proving the declared default is active.

…R-0056 D7) The new isDefault property on PermissionSetSchema is a governed-type property and must be classified for the spec-liveness gate. Marked live — the SecurityPlugin constructor reads it to resolve the fallback profile; proven by the showcase-default-profile dogfood test.
