Builds n3xd-ocp end to end and publishes 7.9.3.1.dev1 to the Gitea registry, where it installs anonymously and passes its suite. - occt/Dockerfile: OCCT 7.9.3 compiled once into a manylinux_2_28 builder image (base digest + tarball sha256 pinned), Draw/VTK/Tk/Xlib/OpenGL off, FreeType on, -O2 without fast-math or march=native. A final layer asserts TKService/TKV3d exist with no libGL/libX11 DT_NEEDED, which is what lets the app image drop libgl1/libx11-6. Mounted into, never built FROM. - scikit-build-core + nanobind STABLE_ABI -> one cp312-abi3 extension that registers every OCP.* submodule via PyImport_AddModule, so `import OCP.TopoDS` needs no shim and cls.__module__ is right. Version <occt>.N is asserted against the OCCT found, keeping occt_version() truthful. - occt_handle.h: type caster for opencascade::handle<T> over OCCT's intrusive refcount. Wrappers are non-owning instances holding exactly one handle in their keep-alive list, reusing an existing wrapper so identity survives a round trip. Transient constructors go through ocp_new (never nb::init<>, which would let OCCT delete nanobind's storage); the caster refuses a refcount-0 object rather than corrupt the heap. Verified under ASAN with no memory-safety errors, plus an RSS bound over 50k create/destroy cycles. - Sub-shapes are returned by value everywhere, making the TShape lifetime class that segfaulted a process-global face memo unrepresentable. - Standard_Failure derives RuntimeError, with ~20 concrete types dispatched on the dynamic OCCT type (cad_pool marshals failures home by type name). - Inc 0 surface: gp subset, TopAbs, TopoDS (+ downcasts), TopExp, TopLoc, TopTools, BRep, BinTools, Poly, Standard. 34 of the app's 139 symbols. - n3xd_ocp: additive APIs kept out of the OCP namespace so parity testing stays meaningful. bintools (shape <-> bytes, GIL-free, byte-identical) and _debug. Two findings worth the record, both verified against the stock wheel rather than assumed: upstream binds __hash__ but leaves __eq__ at identity, which is exactly what geom_memo.py's hash-bucket + IsSame scan is built around, so we match it instead of "fixing" it; and BinTools can release the GIL after all, by slurping the file-like object instead of bridging a streambuf that would call back into Python. Gate: BREP round-trips are byte-identical to cadquery-ocp-novtk across six fixtures (the generator asserts stock idempotency first). That matters beyond IPC — derive.py content-addresses BREP payloads by sha256 and stores the ref.
