# Delivery review

The completed kit contains 19 named atoms and the exact 12-name shelf. Total geometry is 7,108 triangles; every atom is below its specified limit. The uncompressed GLB is 1,032,532 bytes and has no embedded images. The external shelf is 19,621,493 PNG bytes, approximately 154.3 MiB as conservative RGBA8 with mipmaps including optional Height images.

The source builder checks finite coordinates, non-zero face areas, closed component topology and identity root transforms. The strict exported-GLB audit finds no invalid attributes, degenerate triangles or duplicate primitives. Metric UV edge error is below 0.000005 m. The planter preserves four grass colour variants in COLOR_0. Browser inspection loads the actual exported GLB and external maps without reported JavaScript errors; see runtime_check.json for measured render counters. Software WebGL is not a target-device performance benchmark.

An independent Claude Sonnet visual review returned PASS after inspecting the user reference, kit/material sheets and browser wall-fit, planter and joint images. Remaining observations were optional presentation polish: dark bronze reads near-black under the neutral studio environment and dark glazing benefits from richer environment reflections. These do not alter the requested dimensions or material names. The earlier proposed changes to narrow the boards and shorten the reveal were rejected because they contradicted the user's 120 mm + 8 mm timber pitch and deep reveals in 350 mm walls.

The wall-fit check identified a sill bedding issue in generated panels. A 44 mm relief below the nominal opening now exposes the folded aluminium sill correctly; this installation allowance is explicit in kit.json and the preview generator. No generated wall is exported as an atom.

A Blender 5.2 glTF exporter issue whitened planter vertex colours on the multi-material mesh. The builder restores COLOR_0 from exact source vertex positions after export, asserts every match, and renders the corrected GLB after reimport. The exported-data validator checks that all four grass colour variants remain present.

Ready for assembler review. This delivery does not claim game integration, optical glass, collision meshes.
