138/138 symbols across 53 modules. New: IFSelect, Interface, XSControl, IGESData, STEPControl, IGESControl, RWStl, Graphic3d, NCollection, StdPrs. **The full app suite passes against this wheel: 1797 passed, 1 skipped — the same result as the stock wheel**, run from the parity venv. Getting there needed six methods that no static analysis could have found: `inventory --check` only sees symbols reached through an import, so a method called on an instance is invisible to it. The suite found them in one pass, and one of them (gp_Vec.Reverse, which every outward-normal probe calls) accounted for 311 of the 255 failing tests on its own. The others: gp_Trsf.SetMirror over a plane and a point, Geom_Surface.D0, BRep_Builder.MakeFace from a triangulation, MakePipeShell.SetMode with a fixed binormal, and MakeFace from a surface plus tolerance. Open question **S5 is settled: no**. The wheel does not need OCCT's share/ resources. test_inc3_io.py asserts no CSF_* variable is set and then round-trips STEP and IGES, reading the declared units back off both — which is exactly the resource-less container the question was about. The XSTEP readers keep the GIL, amending the blanket "file readers and writers" line in design.md's GIL policy. STEP and IGES traffic in process-global Interface_Static state, the IGES reader is documented as not thread-safe, and the app already serialises imports behind a lock — so holding it costs nothing and removes a class of question. RWStl, which touches no global state, releases. XSControl_Reader and IGESData are registered although the app imports neither: they are the reader base both concrete readers inherit their transfer surface from, and the model-to-global-section chain the IGES unit probe walks.
