Break apart four large files that had grown unwieldy: wrap/occt_wrap.cpp (9738 lines) → 27 domain .cpp + occt_wrap_internal.h wrap/occt_wrap.h (998 lines) → 28 domain sub-headers + master include t/smoke-tests.lisp (4307 lines) → 33 domain-specific test files src/ffi/bindings.lisp (2389 lines) → 28 domain binding files Summary of changes: - Each .cpp file includes only its own sub-header for incremental builds - Parallel Makefile (make -j) reduces clean build to ~4.5s - Incremental builds take ~1.7s (single file + relink) vs 2s full rebuild - Added missing graphic3d_group_set_visible stub (was declared but never implemented) Build system: just wrap delegates to wrap/Makefile with -MMD dependency tracking for correct incremental rebuilds on header changes.
… null-pointer crash - Rename test to graphic-group-add-triangles-valid to avoid deftest shadowing the function being tested (invalid number of arguments). - Pass cffi:null-pointer instead of nil for optional normals parameter to satisfy CFFI :pointer type requirement. - Add free-graphic-group public API for explicit group resource cleanup. - Fix cleanup condition to check &key normals instead of bound norms.

transaction API
- ocaf-attributes: integer/real/string/name attribute set/get/has
- ocaf-naming: shape naming with evolution keywords (:primitive :generated
:modified :deleted :selected)

- Remove dead v3d_view_set_transparent_shading duplicate declarations from wrap/occt_wrap_visual.h (function was never implemented in C++) - Fix xcaf_get_layer_count to use GetLayers() per-shape instead of GetLayerLabels() (was returning all document layers, not per-shape) - Implement xcaf_get_layer_name C wrapper via XCAFDoc_LayerTool::GetLayers() - Implement xcaf-get-shape-layers core function (was stubbed as not-yet-implemented)
