  "description": "task-2553+54 — ANU runtime event loop result. The loop interprets a durable-registry (callback_4tuple_index.jsonl) append/update as a progress event and immediately drives the next step: single-task next_action (+47), batch all-settled (+53), consolidated summary candidate, and a next-phase ANU-key dispatch CANDIDATE. The registry is the state source (read-only); schedule_history is audit only; a fixed-time gate / dead-man fallback is NEVER a progress trigger (FORBIDDEN_TRIGGER_SOURCE). All outputs are proposals — the loop has zero dispatch/merge/write authority.",
