Create expiring public review and direct-download URLs for one exact finished BitterClip render. The review URL is the practical human handoff; download_url remains the primitive for external services that ingest a public video URL (captioning/styling connectors like Submagic, Zapier steps, publishing tools). Pass exactly ONE target: episode_id when you have an Episode/derived-clip handle, OR render_id when you only have the ready render artifact; never pass both. A derived clip's comp_... handle goes in episode_id. This tool never starts or retries rendering: if render_not_ready, call render_create and wait for render_status to report ready, then retry with one target. Repeating the call for the same ready render is safe and does not enqueue or mutate a render; it only returns fresh expiring bearer URLs. A later render invalidates these links rather than silently showing a different cut. When a UI supplied expected_render_generation, pass it back so a stale card fails instead of sharing a newer Render. Pair download_url with title and dictionary when the receiving service wants context.
