- **int8 (dynamic)** — delta-1 against the fp32 build is 0.994 median over ten real images and 0.975 at worst — for reference, depth models report delta-1 near 0.95 against ground truth, so the quantization error sits well inside the model's own error.

- **int8 (dynamic) is not shipped**: measured in the units that matter for this model — fraction of pixels within 1.25x of the fp32 depth: median 0.9941 over 10 real images, worst 0.9748.
