Live cdb read on the PDB-paired retail client (owner's AMD GPU): m_caps.bCanDoSinglePassDetailing = 1, trysinglepass = 1, MaxSimultaneousTextures = 8, bTexOpDotProduct3 = 1, LandscapeDetailTextures = 0, EnvironmentDetailTextures = 1, landscape/object detail surfaces null, building/environment non-null, tiling 4 everywhere. So retail's detail combine on modern hardware is the texture-stage path in D3DPolyRender::SetSurface (stage0 alpha PREMODULATE, stage1 colour BLENDCURRENTALPHA): lerp(base*diffuse, detail.rgb, detail.a*diffuse.a) - a mild DARKENING (~-10% mid-tones with 0x06006D58), not the DSTCOLOR+INVSRCALPHA brightening that Campaign AR ported and that the 2026-08-21 findings doc + AR review both analysed. Those described the fallback for adapters without D3DTEXOPCAPS_PREMODULATE; the reviewer's guess that consumer drivers rarely advertised it was wrong. VM1 now carries the re-port (SRCALPHA+INVSRCALPHA, detail.rgb / detail.a*diffuseAlpha, neutral at a==0) together with the fade removal. No distance fade exists on either path. Scripts are read-only attaches with no breakpoints. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* Campaign VM slice VM2 - which detail-texturing path does retail run on this GPU?

* Read-only: attach, dump the capability + detail state, detach. No breakpoints.
