Function buildHistoryEntry

buildHistoryEntry(
    opts: {
        earlier: string;
        earlierMarker?: number | null;
        later: string;
        laterDate?: string | null;
        laterMarker?: number | null;
    },
): string
Build ONE History trajectory line preserving BOTH sources' citation markers: the earlier position (past) carries [^earlierMarker], the later/current one carries [^laterMarker], so no provenance is lost. Both values are real article data, not copyable example values. Pure.
Parameters
- opts: {
      earlier: string;
      earlierMarker?: number | null;
      later: string;
      laterDate?: string | null;
      laterMarker?: number | null;
  }
Returns string
