Outcome (a). Original recordings/diffs retained. Each HEAD-on-Z still matches its original BASE-before still at zero threshold across all 1,296,000 pixels. See sheets, statistics and band-pixel-verification.json. HEAD was the real app at ace518f2a78ebd640e1d5b06a652bd9d5c42b047, using a fresh isolated database, synthetic RPC seed, fixed clock, Chromium 148.0.7778.96, 1440x900 dark, DPR1, reduced motion and two identical screenshots 500ms apart. No base checkout needed. R01 A-reopened-after-Z differs from original AFTER only at the same nine pixels; navigation history matters. R03 draft control differs only in its hero region (10,854 pixels, x472..1023 y316..373); original evidence is retained. No credentials or real user data included. All owned processes stopped; HEAD unchanged.
