63// Module map — offset_shell is split into topic submodules (moves only).
64// This file stays the module root: shared imports, the `os_debug!` macro, the
65// public result/record types, and the `Carrier` type live here.
66//
67//   carriers.rs        — carrier construction, pair imprinting, fragment/skin
68//                        classification helpers
69//   smooth_sync.rs     — carrier bounds/extent sampling, adjacency/tangency
70//                        probes, smooth-boundary synchronization
71//   carrier_rebuild.rs — carrier trim rebuilds: hole-rim extension, fall-short
72//                        curved carriers, full-domain + reflex-rim rebuilds,
73//                        opening-wall seeds
74//   connectors.rs      — open-boundary tracing: sharp offset connectors,
75//                        duplicate-arc welds, opening-boundary cycle completion
76//   orientation.rs     — open-solid orientation, orphan-rim welds, face/shell
77//                        flip helpers
78//   rim_welds.rs       — rim-circle fitting, cap faces, ruled offset rim
79//                        welds, coplanar rim-pair annuli
80//   pipeline.rs        — the offset_shell entry points and the
81//                        offset_shell_impl assembly/validation pipeline
82//   tests.rs           — the `#[cfg(test)]` battery
