Runtime Lifecycle

Plan, start, and poll one bounded study. Callers name source and range; the scheduler owns tasks, grants, and budgets.

POST/v1/runtime-plansPlan one bounded study and return its forecast without starting anything. Accepts the same body as /v1/runtime-starts.

studio.local-runtime-plan.v1

Request Body

application/json
sourceSessionIdstringrequired

Registered source session to study.

sourceRevisionIdstringrequired

mode is "declared", "automatic", "mixed", "unknown", or "withheld". declared takes exactly one language, mixed at least two, withheld requires a reason.

targetLanguagestringrequired

Translation target, for example "en".

selectedLanguagePackIdstring | nullrequired

Language pack to apply, for example "ko-v3".

outputDepth"captions" | "evidence"required

How deep the study output goes.

optionsobjectoptional

Analysis options, validated by the host.

clientRequestIdstringoptional

Client-supplied request identifier.
