# BREP_reconstruction
`BREP_reconstruction` owns code that needs both the kernel-free
`BREP_RANSAC` recognizer and `BREP_kernel`: mesh/metadata conversion,
carrier-to-kernel conversion, hybrid analytic/faceted reconstruction, STEP
validation support, and the STL-to-STEP conversion pipeline.
The crate re-exports the `brep_ransac` public API. Integration-specific APIs are grouped
under:
- `brep` for kernel mesh/metadata conversion, analytic carrier conversion, and attaching
face metadata;
- `step_validation` for STEP validation reports, progress, and CSV output;
- `stl` for ASCII/binary STL parsing and welding;
- `stl_conversion` for recognition, hybrid/faceted fallback, and validated AP214 STEP
serialization.
It is a library-only package, versioned 0.2.1, released 2026-09-11. Its
`BREP_RANSAC` and `BREP_kernel` dependencies carry a registry `version` beside their
repository-relative `path`; the kernel dependency is pinned EXACTLY (`=0.5.0`), so the two
move in lockstep. It also depends on `serde` and `serde_json`. It publishes after
`BREP_RANSAC` and `BREP_kernel`, and before `BREP_render`.
