Opt-in at build time (VOXELFORGE_PROFILE_LEGACY_TERMS=1; compiled out by default, ~2% when on). Per legacy sample: passage/support composer ~1.05 us vs primitive scan ~0.19 us, boundary band ~0.06 us, noise ~0.01 us. Resolved-passage constants are cached at field binding (arithmetic order unchanged); whole-view effect within noise. Per-tile hashes identical to L75 in all 24 compiler x worker x view comparisons; fast tier PASS; Linux UE host builds. R40 researcher notes attached.
