The per-request SELECT users WHERE uuid=? in require_role was the hidden tax behind every authed endpoint — it kept _execute at ~60% across the profile even after the page caches landed. Even /health (with its DB and Docker probes cached) was still 52% _execute from this one query. - dependencies.py: 10s TTL cache on get_user_by_uuid, well below JWT expiry. invalidate_user_cache(uuid) is called on password change, role change, and user delete. - api_get_config.py: 5s TTL cache on the admin branch's list_users() (previously fetched every /config call). Invalidated on user create/update/delete. - api_change_pass.py + api_manage_users.py: invalidation hooks on all user-mutating endpoints.
