# GPU Governor / Hero Integrity manual checklist

1. Open `/play/?build=f49access58` and enter the garage or North Berwick Free Drive.
2. Press `F8` or open **TUNING → GPU**.
3. Confirm a WebGL2 renderer before evaluating GPU tiers.
4. Confirm `heroIntegrityOk: true`, `heroMissingBatches: 0`, and matching required/rendered hero batch and instance counts.
5. Verify the factory-model report identifies 107 source primitives consolidated into six complete-material batches.
6. Compare quality, balanced, recovery, lean and protect. Buttercup’s complete body, glass, lamps and wheels must remain present in every tier.
7. Confirm the report distinguishes `gpuDrawBudgetFloor`, `gpuDrawBudgetStatus`, optional `gpuPassPlan`, and any pass skips.
8. Verify lower tiers reduce optional reflections, shadows, probes, bloom, FX or nonessential decoration before any required hero geometry.
9. Export the JSON report manually when filing a playtest issue.

For automated local QA only, append `?renderer-audit=1`; this exposes `window.REBORN_RENDERER_AUDIT` with mode forcing and fail-closed assertions. Nothing is uploaded automatically. Synthetic browser checks are not physical-device GPU, FPS, thermal, battery, memory or storefront certification.
