Document deviations from the OpenLR whitepaper - #29
Merged
Conversation
Audit of the decoder against openlr-whitepaper_v1.5 (Chapter G §12). Adds a 'Known Deviations' section to CLAUDE.md and a summary to README covering HERE-isms (last-LRP bearing in travel direction, ignored binary offsets, FRC0-4 only) and unimplemented spec features (multi-LRP consistency, PointAlongLine offset/SOR/ORI, BEARDIST bearing, partial FOW inference, unsupported location types). Also corrects the max_candidate_distance_m docstring: it gates the decode on at least one LRP having a close candidate, not each candidate. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
