- Static obstacles and routed paths are treated as single-layer geometry; automatic crossings are not supported.
- The danger-map implementation uses sampled obstacle-boundary points and a KD-tree, not a dense distance-transform grid.
- The visibility subsystem keeps a lazy static corner index for default `tangent_corner` guidance and only builds the exact corner-to-corner graph on demand for `exact_corner` queries.
- `use_tiered_strategy` can swap in a cheaper bend proxy on the first congestion iteration.
- Negotiated congestion now re-verifies every reached-target path at the end of each iteration against the final installed dynamic geometry, and it stops early if the conflict graph stalls for consecutive iterations.
- Final `RoutingResult` validity is determined by explicit post-route verification, not only by search-time pruning.
