Four mechanical binding edits; the bound Python surface is unchanged (sigdiff compared the 7.9.3.1 dump against 8.0.1.1's in both directions and found no class, member or constructor arity moved), so the app needs no change. - NCollection_Utf8String is gone; NCollection_String is the same UTF-8 type. Python name kept, since the app imports it. - Standard_Failure lost its Standard_Transient RTTI when it moved to deriving std::exception; ExceptionType() replaced DynamicType()->Name() and returns the same class names the exception dispatch keys on. - FindKey gained a size_t overload beside the int one, so the plain member pointer is ambiguous; overload_cast picks the int form, which keeps the negative-index guard. - StdPrs moved from TKService to TKV3d, so CMakeLists links both. The byte-identity fixtures did NOT retire, contrary to the watchlist: all six round-trip to the same digests under the new kernel, as do the measurement, history and mesh-count blocks, so tests/data is untouched and the app's content-addressed BREP payloads stay valid. Gates: binding suite 83 passed, 138/138 symbols, sigdiff clean both directions, ASAN clean, app suite 1798 passed / 1 skipped (unchanged), sweep over 4486 parts with anchors_digest and every status unchanged, -m perf 16% faster on the 32-feature chain.

# OCCT builder image — a compiler appliance, not a base for the wheel.
|
|
#
|
|
# Wheel builds `docker run` this with the repo mounted (see ../Makefile); they
|
|
# never `FROM` it, so iterating on the binding never re-layers the kernel.
|
|
# Rebuild only when this file changes, and bump the image tag's -N when you do.
|
|
#
|
|
# The production host (4 cores) can never compile OCCT, which is the whole
|
|
# reason this exists: the kernel is compiled once here and shipped inside the
|
|
# wheel by `auditwheel repair`.
