description	QA checklist for OpenVSP geometry work in open-air. Use when editing or reviewing src/openair/geometry/**, geometry.json, .vsp3/STL exports, packing, or anything touching the OpenVSP Python API.

Geometry QA

Read docs/guidebook/01-openvsp.md and execute its "Check your work" list.

Non-negotiables for this repo:

• OpenVSP setters fail silently: any new SetParmVal needs read-back coverage in build_openvsp_model's verification block, and errors must be drained via vsp.ErrorMgrSingleton.getInstance() (module-level error functions do not exist).
• Read-back proves values, never choices: a wrong rotation axis reads back "correctly" while the exported mesh is garbage (audit F14). The stage ok therefore requires readback.matches_spec, stl_bbox.ok, AND mesh_checks.ok (per-component extents, fin verticality, attachment, computed whole-model height — all measured from the exported STL).
• Always open threeview.png: it is rendered from the exported mesh, not the spec. If you change the builder, look at it before trusting any number.
• Set wing driver groups before planform parms; pin Sweep_Location to 0 for LE sweep; Update() before any read-back or export.
• MassProp Total_Mass is unitless volume-proxy unless densities were set — never quote it as kilograms.
• Packing: payload bay must clear the engine compartment front (L - 0.20 - engine_length - 0.05) and fuel volume must fit wing tanks + fuselage leftover (packing_report).
