**Verdict: PASS.** The concerns below are polish, and the bedding-pocket fix is already in progress, so none of them should block delivery.

1. **Bronze reads as near-black.** In `runtime_assembly.png` and `runtime_joints.png`, the frames, sills and linings look black. In `kit_sheet.png` they read as dark brown. The reference sheet shows a warmer, lighter bronze. The kit does meet "dark bronze", but a small lift in the bronze albedo or a warm rim would help. Optional.

2. **Wall-top material on the sills.**
   - In `runtime_assembly.png`, the timber and render show through at the sill lines on the upper windows and on the ground-floor window. This is the bedding-pocket issue you already know about.
   - Re-shoot the wall-fit once the 44mm fix lands, to confirm the sills sit clean.

3. **Glass has a flat, slightly blue-grey look.**
   - It is dark and has no interiors, as specified.
   - Reflection is faint in the runtime views and the glass looks matte. The kit sheet's lighter glass reads as frosted rather than reflective.
   - This is a render and lighting limit, not a kit defect. Don't change the geometry.

**Checked and fine:**
- **Window frames:** the hood look in the isolated kit-sheet thumbnails is expected. In the wall-fit the frames read correctly inside the reveals.
- **Larch:** the 120mm boards and 8mm gaps read right, and the scars are gone.
- **Planter:** the grass colour is preserved, and the concrete and its tie-holes look good.
- **Downpipe:** square, with a shoe and head that read clearly.
- **Coping and corner:** the joint reads cleanly.

I looked only at the six images you named. I didn't check the triangle counts or the files themselves.
