Exact-pixel and production-perf comparison of6c79d35c(+ only the A2 normal files, so no terrain mask is needed) againstc51b07efwith no pack: connected as +Acdream, visible window, one isolated config clone per variant, pinned clocks. Open field: the only differences are idle pose, mana digits and a passing flyer. Holtburg: same-binary-twice defines the dynamic mask (9.8%); in the static 90% both self-diffs have ZERO pixels with |d|>=8 while base+normals vs HEAD-off has 841/729 - all streaks inside the animated lifestone. Buildings, ground, trees, sky and UI are clean. Perf (uncapped Release, no automation observer, ACDREAM_FRAME_PROF=1): Holtburg CPU p50 4.7 -> 4.1 ms, Arwic 6.0 -> 5.2 ms, GPU unchanged, alloc/frame 574 KB -> 21 KB. No regression; F5b's '27.8 ms retail CPU' was the observer. Three false alarms recorded so nobody repeats them: the isolated gate settings lack fieldOfView (90 vs the real 86.33 -> a 0.952 zoom); the real %APPDATA% settings still selected acdream.atmospheric/low (pack ON); a minimized GLFW window is throttled and never settles. Tools: tools/vm0/capture-visible.ps1 (pre-campaign gate + -Exe/-Live/ -ConfigDir/-CharacterName/-PreCaptureCommand), tools/vm0/perf-run.sh, and -BuildingDetailTextures on run-offline-pixel-gate.ps1. Baseline patches under docs/research/evidence/vm0/. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
