visual-check

Run /visual-check with the render path, for example /visual-check tests/reference/disney_contact_sheet_post_compensation.png. It reads the image with multimodal capability and returns a short note on exposure, artifacts, and material fidelity.

Pass both paths to /visual-check, such as /visual-check test_results/optix_before.png test_results/optix_after.png. The output includes a comparison delta describing what changed, whether it improved, and any regressions.

The inspection covers fireflies, banding, NaN pixels appearing as magenta or black spikes, aliasing, and moire. It also checks material fidelity, such as whether metals look metallic and glass looks transparent.

No, this is a qualitative pass only and does not replace the numerical gates in the hardware verifier. When the image looks wrong but the numbers pass, escalate to gate-failure-reviewer.

Yes, the inspection note includes a spectral signature section covering visible dispersion, chromatic effects, and band-specific artifacts when applicable to the render.
