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.

BoundaryA physical constraint on barge draft and transit capacity.
ExcludedWell understood and seasonal. Rarely a surprise.
Known errorThe registry records a hourly cadence and a worst-case lag of 0–2 h. A current reading is not shown until its source receipt is retained with the reviewed package.
FalsifierA reading that conflicts with the boundary above, or cannot be independently corroborated where corroboration is required, does not support a desk claim.
