Radiance reference bundle, scene corpus 4 (Metal campaign of 3 Nov 2026)

Converged Radiance references for the 106-scene architectural corpus (scene corpus version 4), both sky densities, 212 cases, exported with scripts/export_reference_bundle.py from the Metal release campaign validation/results/2026-11-03-architectural-v4-metal-0.3.0 (commit f65030f, Apple M4 Pro, Radiance 5.4a, six hours with twelve workers).

Per case: the converged full coefficients (mean of the 80,000-ambient-division, 12-bounce replicates), the last integrated-direct level, the mean one-bounce level, the stability verdicts and the sensor grid in model order. The references describe the scenes, not the engine, so any GPU backend can be judged against them without redoing Radiance:

unzip foton-references-corpus4-2026-11-03.zip
python scripts/validate_release_suite.py --backend vulkan --workers 2 \
    --reuse-references foton-references-corpus4-2026-11-03 --output <new dir>

Requires a checkout at 87f96a0 or later. The suite refuses the bundle for any other corpus version and records its provenance under reference_source in every report.

This is not a Foton release; it is validation data. SHA-256 of the zip: de4be5a59e4b694d0c9f8f5ef697649527e45dd231d9794b23ff7a9f8038417b
