autonomous_room_image_apply

# autonomous_room_image_apply

Upload one autonomous room image in the Messenger app (pApp D00003). Requires change {action:"upload"}. Upload from this computer: target upload {kind:"local-file", filename, byteLength, sha256} returns one presigned PUT with its headers and the console room screen link; send the file, then call again with upload {kind:"complete", uploadId, parts:[{partNumber:1, etag}]}. The server never receives the file or downloads a link. Write: uploads to storage only; use the taskId in autonomous_room_create_apply (no roomId) or autonomous_room_image_replace_apply (same roomId). A lost receipt stays pending and is never resent; task_resume only observes, and prepared work needs the identical apply. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.

## Inputs

| Field | Required here | Contract |
| --- | --- | --- |
| `target` | Yes | object; upload: start with {kind:"local-file", filename, byteLength, sha256} for a JPEG, PNG or GIF under 10,000,000 bytes on this computer, send it with the returned PUT, then finish with {kind:"complete", uploadId, parts}. A Google Drive or other link must be downloaded to this computer first. Add roomId for an existing room; omit it for a new room. |
| `target.upload` | Yes | one of: `local-file`, `more-parts`, `complete`, `cancel` (by `kind`) |
| `target.upload.filename` | Yes | When `target.upload.kind` is `local-file`: string; min length 1; max length 240; pattern `^[^/\\:\x00-\x1f\x7f]+$`; The name of the file on this computer, with its extension. |
| `target.upload.byteLength` | Yes | When `target.upload.kind` is `local-file`: integer; greater than 0; The exact file size in bytes (for example from `wc -c < FILE` or `stat`). |
| `target.upload.sha256` | No | When `target.upload.kind` is `local-file`: string; pattern `^[0-9a-f]{64}$`; The SHA-256 of the file in lowercase hex (shasum -a 256 FILE). Required when the upload answers UPLOAD_CHECKSUM_REQUIRED. |
| `target.upload.uploadId` | Yes | When `target.upload.kind` is `more-parts`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `target.upload.fromPart` | Yes | When `target.upload.kind` is `more-parts`: integer; minimum 1; maximum 10000 |
| `target.upload.uploadId` | Yes | When `target.upload.kind` is `complete`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `target.upload.parts` | Yes | When `target.upload.kind` is `complete`: array; min items 1; max items 10000 |
| `target.upload.parts[].partNumber` | Yes | When `target.upload.kind` is `complete`: integer; minimum 1; maximum 10000 |
| `target.upload.parts[].etag` | Yes | When `target.upload.kind` is `complete`: string; min length 1; max length 200 |
| `target.upload.measured` | No | When `target.upload.kind` is `complete`: object; What the video measures on this computer, read with measureCommand. |
| `target.upload.measured.durationSeconds` | Yes | When `target.upload.kind` is `complete`: number; maximum 1000000; greater than 0; Video duration in seconds (ffprobe format.duration). |
| `target.upload.measured.frameRate` | Yes | When `target.upload.kind` is `complete`: number; maximum 1000; greater than 0; Frames per second (ffprobe avg_frame_rate, for example 30000/1001 = 29.97). |
| `target.upload.measured.width` | Yes | When `target.upload.kind` is `complete`: integer; maximum 100000; greater than 0 |
| `target.upload.measured.height` | Yes | When `target.upload.kind` is `complete`: integer; maximum 100000; greater than 0 |
| `target.upload.measured.frameRateMode` | No | When `target.upload.kind` is `complete`: `CFR`, `VFR`; Constant or variable frame rate, when the tool reports it. |
| `target.upload.measured.minFrameRate` | No | When `target.upload.kind` is `complete`: number; maximum 1000; greater than 0 |
| `target.upload.measured.maxFrameRate` | No | When `target.upload.kind` is `complete`: number; maximum 1000; greater than 0 |
| `target.upload.uploadId` | Yes | When `target.upload.kind` is `cancel`: string; pattern `^upl_[A-Za-z0-9_-]{22}$` |
| `target.roomId` | No | string; min length 1; max length 200; pattern `^[^/?#%\\\s]+$` |
| `change` | Yes | object |
| `change.action` | Yes | `upload` |
| `confirmToken` | No | string; pattern `^ct[a-f\d]{32}$`; The confirmToken from this tool's preview result. Omit it to preview; repeat the same input with it to execute. |
