JWT access tokens freeze role/identity at login (access 1h, refresh 7d)
and validated tokens are cached for 30s. The Bearer and cookie auth paths
trusted claims.role and never re-checked the account, so demoting an admin,
or disabling/deleting an account, did not revoke access until the token
expired. The app-password path already re-read role/active from the DB;
only the JWT/cookie path had the gap.
Re-validate the caller against the live user record on the token path via
the already-cached get_user_flags (role / is_external / active), bounded by
USER_FLAGS_CACHE_TTL and invalidated eagerly on set_user_active /
change_user_role / delete_user_admin:
- middleware/user.rs: new resolve_live_role helper (+ pure decide_live_role
core) — returns the *current* role, rejects deleted (NotFound) and
deactivated accounts, and fails open on transient lookup errors (mirrors
require_internal_user). Login/refresh remain the canonical active gate.
- middleware/auth.rs: auth_middleware (Bearer + cookie) now populates
CurrentUser with the live role and rejects revoked accounts (Bearer ->
401 AccountInactive; cookie -> fall through to 401/login redirect).
require_admin emits an audit line on denial.
- middleware/admin.rs: require_admin / require_authenticated re-check the
live record, return the live role, and audit admin denials.
Downstream admin gates (dedup_handler, subject_group_handler, OCS) inherit
the live role automatically via CurrentUser / require_authenticated.
Tests: decide_live_role policy (active / demoted / deactivated / deleted /
transient fail-open) and AccountInactive -> 401.
