- Permission enum + GroupName enum + GROUP_PERMISSIONS mapping mirror
the F11 matrix in code (verifiable against the spec table in tests).
- @require_perm decorator: 401 on anonymous, 403 on missing permission,
passes through otherwise. Pure-function user_has() for unit-testing.
- AuthUser (Flask-Login wrapper) resolves the permission set from a
User's groups; load_user is the Flask-Login user_loader.
- bcrypt password hashing helpers (12 rounds by default, configurable).
- SOC opaque token (D-006): secrets.token_urlsafe(32), bcrypt-hashed at
rest, plain value returned once at creation and never re-displayable.
- Group-based RBAC from day one (D-003) — Keycloak OIDC in v2 maps onto
the same group model.
