Where this rule applies
This water is not yet drawn on the map. Its rules are captured and receipted; the geometry ledger records exactly why it is not drawn (an ambiguous name match or a gap in the source data), and it will never ship as a guess. Each rule above describes in the state's own words where it applies, and those written descriptions are the authoritative boundaries.
