Task 1 fix round 2 review package

Review only the remaining atlas-exclusion finding from fix round 1.

Files

• Current regression: D:/project/behind_glass/scripts/test-surface-reflection.mjs
• Updated report: D:/project/behind_glass/docs/qa-surface-reflection/implementation-report.md
• Unchanged production shader: D:/project/behind_glass/src/shaders/mosaic.frag
• Preserved baseline: D:/project/behind_glass/docs/qa-surface-reflection/baseline-mosaic.frag

Evidence

• Production shader SHA-256 unchanged: 5FB0AE93482AF46833B076EABFB0018E8BFEBA0A83BFD244DCD210371E450180.
• Current test SHA-256: E4430C19827D0253C5E3EF073D702170C9552E3CAD09997D00D1C0405A66ED8A.
• Command: node scripts/test-surface-reflection.mjs
• Output: surface reflection source/math regression passed; constant-output and atlas-reflection mutations rejected

The test now compares the complete source segments executed while REGION_ATLAS is defined against the preserved baseline and applies a mutation that inserts gloss-dependent white mixing in an earlier atlas section. That mutation must be rejected.
