Current observation state

No custody-backed current observation is packaged for this series. ARCANE exposes the method, boundary, and lag now; it will not draw an indicative series until the source record, retrieval receipt, and observation timestamp travel with it.

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.

Breaks the read
Transit 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.
