Package comment said "Stage-0 ... (ADR-011)" and User.Subject said "single-user allowlist (ADR-011)". Both stale: ADR-012 opened Stage 1 (multi-user, RLS-enforced isolation). Subject is now the user_identities lookup key (migration 004) resolving to a per-user UUID; an unknown subject hits the registration gate.
