## 4. How to Run
### Optional JamesDSP integration check
`node perf/dsp.mjs --browser all` builds short local H.264/AAC test tones, exercises Standard and the lazy JamesDSP presets through the real app audio graph, compares the A/B-bypassed RMS to Standard, verifies one worklet heap and no extra media sources, tests the offline cached reload, and injects a failed WASM response to check Standard fallback. Its detailed measurements stay in ignored `perf/.tmp/dsp-results.json`.
`node perf/dsp.mjs --browser all` builds short local H.264/AAC test tones, exercises Standard and lazy JamesDSP presets through the real app graph, verifies A/B bypass routes directly to the unchanged Standard chain, measures generated-IR effects and the four-channel/spatial stages in an offline render, checks an arbitrary 32 kHz context, and tests stored-IR offline reload, one worklet heap, no new media sources, and corrupt-WASM fallback. The default install must omit the optional WASM; the harness then opts in through Settings and confirms completion. Detailed measurements stay in ignored `perf/.tmp/dsp-results.json`.
`node perf/settings-persist.mjs --browser all` also round-trips a disabled, custom JamesDSP preset through local storage and confirms the Standard selector remains selected.
