Fix same-edge solution rejected by min_distance floor#24
Merged
Conversation
When both LRPs project within 5m of the same edge (excellent spatial match), relax the minimum path length to 0m in addition to the existing relaxed maximum. The 10m min_distance floor was rejecting correct same-edge solutions where the actual path cost was shorter than 10m (e.g., 4.6m on a 261m curved ramp). DNP quantization can significantly overestimate short distances, and close spatial match provides strong enough evidence to trust the result. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
