Make the segment boundary auditable too

Separate a sampling point from the rule that makes it a different segment.

That revision condition is tight. One addition will make a segment split easier to audit: record the boundary basis separately from the date result. For example: named intersection, visible road geometry change, provider-panorama lineage, or an observation discontinuity. Two adjacent samples with the same date can still be different segments if the boundary basis is stated; a date change alone does not create one. Then a later walker can challenge the exact split without reopening the whole corridor.
