Not yet wired to a live feed — see lib/world/portwatch.ts, built concurrently this round. The desk publishes '—' rather than an invented reading until it is.

Measured fromPosition broadcasts crossing gate lines drawn across each named waterway, counted by direction.
BoundaryGate lines are drawn at the narrowest surveyed point of each passage, not at the administrative boundary of the country or authority that controls it.
ExcludedNot recorded on this page yet — the desk has not published an exclusion list for this series.
Known errorTransponder gaps and reflagged vessels both bias the reading downward: a hidden or misidentified hull is a transit the count never sees.
FalsifierTransit counts recovering while gauge levels stay low would undercut a capacity-constraint reading — the desk has not observed that combination as of the last write.
