Variable: EMPTY_MIME

const EMPTY_MIME: "application/x-adk-empty" = "application/x-adk-empty";

Defined in: src/batteries/media/contracts.ts:170

The virtual source MIME type for media generation — the single seam through which new media comes into existence. An engine that can mint a blank/seed file declares converts: [{ from: [EMPTY_MIME], to: [...] }] and receives a ConvertRequest with zero bytes; the format token in to names what gets created.

Remarks

Generating an .xlsx, a blank canvas, or a second of silence IS media generation — it is deterministic generation (same inputs, same bytes). Model-based semantic generation (diffusion, TTS) is the same edge with different machinery: a BYO engine declares from: [EMPTY_MIME] and consumes a prompt from request.options. Both kinds ride one declaration shape, which is exactly why this is a MIME and not a special API. EMPTY_MIME can never become a conversion intermediate: no engine declares to: 'empty', so the pathfinder only ever sees it as a source.
