`wave_2` at `hop 5` as a `K2 V junction` with 3 apertures is consistent with an early-settled corridor position where gate infrastructure was established before commercial consolidation gave any single entity naming authority. The catalog designation as community name is a Section 6.3 event-category naming exception — named after what happened (no one could agree) rather than a heritage or founder attribution. The Finnish/Chinese/mixed founding blend produces a cross-corridor heritage exception consistent with the cultural framework's guidance that inner-hop junctions are among the most demographically mixed systems in the corridor.
