Any ComfyUI workflow runs as a job, from the inputs its catalog entry declares

A model's catalog entry now says what its workflow takes and makes:
comfyui.inputs, each a placeholder of its name with a type (text, int,
float, bool, choice, image, mask, audio, video, file), bounds, choices
and a default; and comfyui.output, which gains video, audio and files
beside pictures and meshes. POST /v1/workflows/runs with {model, inputs}
checks a request against them before a job is written — a required input
left out, an unknown one, a number out of bounds, a song sent as a
picture, another owner's file id are each refused with what was wrong —
and the job worker replays it to a replica, where the files go into
ComfyUI's input directory, the workflow is filled and run, and the first
file of the model's output kind is the job's result. /v1/models lists
each ComfyUI model's workflow, so a client can build its form.

A PNG result carries the licence in an iTXt chunk, as a GLB does in
asset.extras. A file whose server named no type is typed by its name
before its bytes, so a WAV is audio/wav, not audio/wave.

+
+### `name`
+
+`string`
+
+Name is the placeholder's, and the request's key.
+
+### `type`
+
+`string`
+
+Type is one of text, int, float, bool, choice, image, mask, audio,
+video, file. The last five are files, sent as base64, a data URL, or
+the id of a file uploaded to /v1/files, and put in ComfyUI's input
+directory; the placeholder gets the name they were given there.
+
+### `required`
+
+`bool`
+
+Required inputs must be in every request; the others take Default,
+or the workflow's own {{name|default}}.
+
+### `default`
