- Integrate ABAC policies into apply_visibility_filter() (allow/deny with priority)
- Add field whitelist (ABAC_ALLOWED_FIELDS) for build_sql_condition() security
- Add request-level ContextVar for user principals (group_ids, role_id)
- Set principals in deps.py (session + bearer auth)
- Use ContextVar in visibility.py and permission_resolver.py (N+1 fix)
- Add version validation to get_cached_visible_ids() (cache strategy unification)
- Deactivate delegation route (parked — not integrated into resolve_permissions)
- Add 7 ABAC integration tests
All 70 tests pass (7 ABAC + 63 existing). No regressions.
