C3D-TBC613 · Connect TBC curb points (260613) done

DRAFT. Run A 1049-1076 (breaks at TBC END), Run B 1080-1089 (after GUTTER END TBC), plus 4 isolated ~3ft couplets as separate segments (1008/09, 1020/21, 1032/33, 1042/43) - a single chain would cut across the 35-71ft gaps. Layer SS-V-ROAD-CURB.

C# payload

// DRAFT: connect TBC (top back of curb) points into linework on 260613.
// Runs derived from point-number order + break codes (TBC END / GUTTER END TBC) and gap analysis:
//   Run A 1049-1076 (ends at 'TBC END'), Run B 1080-1089 (after 'GUTTER END TBC').
//   1008/1009, 1020/1021, 1032/1033, 1042/1043 are ~3' couplets separated by 35-71' gaps —
//   drawn as separate short segments, NOT chained (a single chain would cut across the gaps).
