Download batch results (alias)

Streams complete provider-native result rows as JSONL for a terminal batch owned by the authenticated workspace. Combines success and error files, converts inline outputs, and follows provider result pagination. Use a Phaseo API key. Downloads do not submit inference or add usage charges. Existing file endpoints remain available. Inline rows are limited to 8 MiB; interrupted downloads must be discarded and downloaded again. Limited to 10 download attempts per workspace per batch in a rolling 30-minute window, shared across API keys and aliases. Failed or cancelled upstream attempts count. A 429 response includes Retry-After in seconds.
