Get It Done

Mint an attachment download URL

GET/v1/attachments/{attachment_id}/download-url

Answers a short-lived presigned GET URL for the attachment's bytes (the SAME signer the in-app proxy and the MCP `get_task_details` tool use). An attachment from another organization (or an unknown id) answers 404 `resource_not_found`.
