The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The generated joint inventory matches block-group-level demographic distributions, reproduces observed spatial population patterns without systematic bias, and maintains consistent allocation quality across urban, suburban, and rural contexts.

C2weakest assumption

The deep contrastive learning model accurately quantifies true housing-household compatibility in a way that, when fed into the hierarchical optimization, produces allocations that preserve realistic joint distributions rather than merely satisfying aggregate constraints.

C3one line summary

A framework integrates synthetic population generation from ACS PUMS, deep contrastive learning for housing-household compatibility, and hierarchical optimization to produce a joint inventory that matches block-group demographics and spatial patterns in coastal North Carolina.
