Objective: establish runtime text/extraction, embedding, and Gemini Live capability without making the provider canonical state.
Accepted evidence: real model calls over an ephemeral Hostinger container qualified text/extraction, gemini-embedding-2 at 768 dimensions, and gemini-3.1-flash-live-preview Live behavior. Errors and bounded retries were classified explicitly.
What later phases depended on: a pinned SDK contract, provider/model/dimension tagging, and the principle that provider state remains replaceable. Account limits were later captured in Phase 5. See docs/evidence/phase-3/2026-09-08-runtime-model-verification/.
