+The terms under which the founding cooperative's inner west_reach fabrication assets were sold. The founding expedition was financed by the liquidation of an established cooperative — a cooperative that was, by the records available, profitable and operational at the time of sale. The community's founding narrative describes the departure as a deliberate choice to pursue deep frontier opportunity. Whether the sale was entirely voluntary, or whether the inner west_reach business environment had become untenable for a cooperative of that type, is a question the founding generation's records could answer and the community does not invite outsiders to examine. The proceeds of the sale are documented; the reasons for the sale are the founding families' private knowledge.

 ## Calibration Note
 
 Wave_3 settlement at hop 15 with a marginal habitable world is explained by the metallic asteroid field that drew industrial settlers specifically for resource extraction rather than agricultural potential. The 300-year continuous operation and the community's economic position in the deep corridor trade network justify the settlement's persistence despite poor surface conditions.
