-         * @description The request body IS the raw gzip build context (context.tar.gz) — not JSON, not multipart — streamed to the platform-derived, id-namespaced location Kaniko reads via --context. The submitter is taken from the principal; a submission the caller does not own is reported as 404, so this endpoint cannot upload to or probe another user's submission. Only a pending_review submission accepts a context (409 otherwise); a wrong-format or oversize body is rejected with 400, and an upload that would push the caller past their per-user stored-context budget is refused with 403 before the excess is persisted. Returns 503 when the deployment's context store has no implemented upload transport.
