The concern is new-user first-contact: see some GOOD summaries fast or they don't return. Reframed as curation/latency for ~3 videos, NOT a 429/throughput problem (3 fetches is nowhere near the wall). Phase 1 (report-and-stop) verifies whether the existing cap-3 onboarding burst even fires today, what it delivers, and — critically — how much transcript-cache overlap exists between users (drives the blend). Phase 2 levers: cached-transcript-first (instant, zero-fetch), likely-good selection (has-captions/good-length, not just newest), and optionally the stronger model for the burst's few summaries. Blend deferred to the maintainer post-Phase-1. Explicitly NOT bulk-fetch, NOT credentials (ADR-010/026 dead end), NOT a client extension.
