GET/api/v1/traces/{traceId}/attachments/{attachmentId}

Get a trace attachment

Returns one span attachment. `?projectId` is REQUIRED (400 MISSING_PROJECT_ID) and the lookup is scoped to project + trace + attachment id (404 NOT_FOUND otherwise). By default the stored bytes are returned with the row's mime_type so the trace UI can render them directly; only the safe-inline set (bitmap images, audio, video, PDF) is served `Content-Disposition: inline` — anything else is forced to `application/octet-stream` as a download, with `X-Content-Type-Options: nosniff` and a `default-src 'none'; sandbox` CSP. Attachments held in object storage answer 302 to their storage URL instead. Add `?json=1` to get the attachment metadata plus the inline base64 payload as JSON.
