System v0.1 — space-claim model

Axis-aligned envelope claims with mass, generated by CadQuery from parameters/*.yaml. Not detailed parts — this stage locks layout, clearances, mass and CoG before any detail design.

Mass & centre of gravity (stowed)

CoG x (0.56 of length)

CoG z (height)

Rendered geometry (the gated assembly itself, not an illustration)

stowed isometric — Stowed — transport state, solar flat on roof

deployed isometric — Deployed — solar wings out at awning height 2 000 mm

stowed floor plan — Floor plan (roof + solar hidden) — colors keyed to the zone table below

deployed top — Deployed floor plan — wing envelopes flanking the container

Pipeline: cad/export_visual.py re-uses the exact claims() the tests gate, exports colored .glb → blender/render_station.py (Cycles CPU, headless) renders. Visuals are presentation of the source of truth, never a separate model (CLAUDE.md visual-lane rule).

Deployed state adds (18 solids)

claim	origin x,y,z (mm)	size (mm)	mass (kg)
solar_wing_left	0, -2400, 2000	12192 × 2400 × 35	448.0
solar_wing_right	0, 2438, 2000	12192 × 2400 × 35	448.0

Solar wings deploy as awnings at 2 000 mm — below the drone-launch cone band (an earlier roof-height layout was rejected by the launch-cone gate).

Independent validation (producer ≠ certifier)

The exported STEP files are re-imported by FreeCAD 1.1.3 (a different geometry kernel path) which re-derives solid counts and bounding boxes and writes a machine-readable receipt — verdict: PASSED, states checked: stowed, deployed, dock_cell, failures: 0.
