Final review package: Ref1 surface reflection

The workspace is not a Git repository. Use the preserved shader baseline and the exact file list below as the complete change set.

Requirements

Read: D:/project/behind_glass/.superpowers/sdd/surface-reflection/task-1-brief.md.

Changed product and regression files

Pre-edit shader: D:/project/behind_glass/docs/qa-surface-reflection/baseline-mosaic.frag
Final shader: D:/project/behind_glass/src/shaders/mosaic.frag
New regression: D:/project/behind_glass/scripts/test-surface-reflection.mjs

The production shader differs from the baseline only in the final non-atlas reflection statement. Its SHA-256 is 5FB0AE93482AF46833B076EABFB0018E8BFEBA0A83BFD244DCD210371E450180.

Reports and review history

Implementer/TDD report: D:/project/behind_glass/docs/qa-surface-reflection/implementation-report.md
Controller browser QA: D:/project/behind_glass/docs/qa-surface-reflection/visual-verification.md
Task review packages/results are summarized in D:/project/behind_glass/.superpowers/sdd/surface-reflection/progress.md.

Task review required two test-only fix rounds. The final scoped review approved complete amplitude/output binding, constant-white mutation rejection, unchanged refraction expressions, complete effective atlas-source comparison, and earlier atlas-reflection mutation rejection. Production shader did not change during either fix.

Verification evidence

Focused command: node scripts/test-surface-reflection.mjs
Focused output: surface reflection source/math regression passed; constant-output and atlas-reflection mutations rejected
The implementation report records six existing scripts passing and npm.cmd run build exit 0 immediately after the production shader change.
Controller browser QA observed no new runtime errors; only the pre-existing X3595 warning remained.
Gloss 0 pane crop was pixel-identical before/after. Default final reflection widened the changed crop coverage from 12.80% to 15.81% relative to gloss 0; the final-vs-baseline mean absolute change was 0.3106/255 and concentrated around the shared top-right light.

Known limits

No GPU screenshot of the intermediate broad-reflection-only stage was captured.
Default-strength visual change is subtle; after-glass-only.png isolates it, while before-default.png and after-default.png are the primary same-condition result.
Real-device mobile performance, continuous-video flicker, touch, and gyro were not measured.
Existing Vite large-chunk advisory and shader X3595 warning remain.
