# IRON-KIDS K2 R45 verification record

## Geometry and lineage

- Supplied assembled source regions: **81**
- Existing bilateral region pairs retained: **2**
- Missing-side mirrors generated: **54**
- Registered assembly-coordinate components: **135**
- Inspection zones: **11**
- Registered reference mesh: **839,781 triangles**
- Browser zone meshes: **14 files / 328,243 triangles total**
- Registered envelope: **506.3573 × 280.1900 × 1325.0000 mm**

## Component topology

- Winding-consistent registered components: **135 / 135**
- Watertight registered components: **0 / 135**
- Micro-fragments under 100 triangles: **5**
- Components whose axis-aligned extents fit within a 400 × 400 × 450 mm volume under at least one axis permutation: **135 / 135**

The bed-volume result is only a bounding-box screen. It is not a print orientation, support, wall, tolerance, slicing, or print-success result.

## Registration consistency

- Every registered component is generated from the assembled source scene, not from a centered local part file.
- The same pointwise eight-band K2 transform is used for every component and the full scene.
- Zone mesh triangle totals are derived from the same component set and sum to the recorded browser total.
- Material mapping is applied by complete component IDs; no triangle-centroid color slicing is used.

## Boundary

These checks establish digital file identity, lineage, shared coordinates, envelope, topology state, and browser packaging. They do not establish fit, comfort, cavity clearance, mobility, printability, strength, safe retention, emergency removal, electrical safety, or suitability for a child.
