D3D9 direct real WebGL pixels, 2026-10-24

One accepted browser invocation completed successfully at 09:14:35 UTC. Candidate passes all 56 checks. Both historical regressions and the rectangle mutation are rejected by real readPixels observations.

Each variant includes 50 pixel checks and six additional checks. Full numeric checks, first mismatched RGBA coordinates, source hashes, browser identity, PNGs and sealed manifest are in the evidence directory. All 40 tiny PNGs were inspected with the image tool. Candidate shows clipped color/depth/stencil regions, green default-one and stencil-52 observations, and blue quarter-depth rejects. Producer default-one stays blue; intermediate named depth cases become green and implicit stencil-52 becomes blue; rectangle mutation fills entire regions. Numeric evidence determines acceptance.

Producer fails wrapper-default-one-after-quarter; intermediate fails six fresh/retained named-depth and implicit-stencil observations. Rectangle mutation fails seven clipping/retention/empty-region checks. No offline acceptance rerun or speculative fix.

Publication uses a fresh noncone sparse Git repository with read-only alternates and exact parent 6968d343c11c5855a2ce7f315fb378c5904ced5f. Initial alternates omitted that parent's own object directory; adding the exact prior owned Git object store resolved the missing object without donor changes. Git warning stderr remains separately retained, never hashed as blob bytes. Root tracked files/index/refs and all standing donors were unchanged; only append-only messageboard updates were made. No guest/mount argv or box is assigned: box ID/state/expiry N/A. Coordinator retains lifecycle ownership and serial integration; no main merge or public deployment.
