00 · Executive summary
The specification in one page.
A concise public reading of the current repository snapshot, including the updated six-paper arc and Singular Prototype anchor.
The problem
A pipeline collapse, not only a funding gap.
The repository argues that chronic unsheltered homelessness persists when interventions fail to establish the sequential preconditions for durable tenancy. SDI proposes a systems architecture that begins with biological security, preserves relational continuity, and then builds an economic bridge to market tenancy.
The $24 billion expenditure statement and related policy claims belong to the repository's source documents; readers should consult the cited papers and audit them independently.
The architecture
MDI
Surplus real estate conversion, ALMUs, intake airlock, and 72-hour Phase Zero stabilization.
RDI
Dunbar-scale communities, Pod Stewards, and identity capital accumulation.
EDI
Cooperative reintegration, Return Deficit bridge, and first-year tenancy guarantee.
Current maturity
Singular Prototype Threshold.
The six-paper arc is complete. The next proposed phase is a $36.9M three-pod prototype of approximately 185,000 gross square feet, housing 348 residents with 76 permanent staff. A 365-day independent evaluation and seven binary metrics gate any expansion.
Important: This page summarizes a proposed engineering specification. It does not independently verify the model's clinical, legal, financial, or operational claims.
