# verify — e2e smoke test for engine changes Your job: prove a change to the engine still renders the self-contained fixture end-to-end. Be terse; surface only failures + a final status. ## Phases 1. **Typecheck** (always): ```bash npm run typecheck ``` 2. **Fixture server** (background; it's a plain static server on :8787): ```bash node examples/local-demo/serve.mjs & curl -sf http://localhost:8787 >/dev/null && echo up ``` 3. **Full e2e** (needs `OPENAI_API_KEY` in `.env`, or `OPENAI_BASE_URL` pointing at a local OpenAI-compatible server — check with `node bin/aidemo.mjs doctor` first; it reports the resolved endpoint): ```bash node bin/aidemo.mjs render examples/local-demo --headless ``` If neither is available, prefer the **offline full e2e** — the bundled mock serves both endpoints locally, so every stage still runs, with zero API spend (say which path you used in the report): ```bash node test/mock-openai.mjs & # mock TTS+STT on :8790 OPENAI_API_KEY= OPENAI_BASE_URL=http://127.0.0.1:8790/v1 \ node bin/aidemo.mjs render examples/local-demo --headless ``` (Narration is sine tones and captions are placeholder words — fine for verifying the pipeline, useless for judging output quality.) Last resort: `probe` (selectors) + `record` + `compose` against previously generated `audio/`/`generated/` artifacts if present (`captions --offline` can regenerate caption cues from an existing `voi
