Open Engineering Specification

Reversing Chronic Unsheltered Homelessness

An uncompromising engineering specification that treats homelessness as a systems failure, not a resource deficiency. Three sequentially dependent layers of infrastructure: Material, Relational, and Economic Dignity.

The Three-Layer Dignity Stack

SDI is a sequentially dependent architecture. Each layer produces the preconditions required by the next. They cannot be deployed independently.

🏢

Material Dignity Infrastructure

Layer 1: Physical Stabilization

Converts surplus commercial real estate into biologically secure stabilization environments via master lease arrangements.

  • ✓ 72-hour biological stabilization
  • ✓ Shelter, nutrition, hygiene
  • ✓ Eliminates multi-year construction
👥

Relational Dignity Infrastructure

Layer 2: Social Architecture

Provides social architecture for identity restoration through Dunbar-scale cohorts and trained Pod Stewards.

  • ✓ Dunbar-scale cohorts (~7 residents)
  • ✓ Pod Steward 1:7 ratio
  • ✓ Preserves relational bonds
💼

Economic Dignity Infrastructure

Layer 3: Economic Reintegration

Establishes cooperative micro-economies to bridge the Return Deficit and enable sustained market-rate tenancy.

  • ✓ Cooperative reintegration
  • ✓ Tenancy Bridge Guarantee
  • ✓ 12-month housing support

Core Concepts

Auditable Infrastructure

Cryptographic, real-time sensor verification of physical unit activation. Eliminates the "Ghost Asset Problem" by requiring continuous verification of unit operational status.

The Return Deficit

The quantified economic penalty imposed by the external labor market upon transitioning residents. The cooperative micro-economy must bridge this deficit for success.

Falsifiability Mandate

SDI defines the exact mathematical conditions of its own failure. Rigid, pre-defined metrics establish hard failure states rather than shifting definitions.

Biological Absolute

Metabolic collapse and thermal exposure are biological absolutes, not political variables. Infrastructure must be engineered to an uncompromising standard.

Falsifiable Metrics

Every measurable claim within SDI specifies the metric, threshold, measurement method, and failure condition.

72-Hour Stabilization

≤ 72 hours

Failure: > 10% of intakes

Real-Time Verification

100%

Failure: Any unit unverifiable > 48h

Social Connection Retention

≥ baseline

Failure: Decline below baseline at 90 days

Cooperative Wage Ratio

≥ 0.85

Failure: Below 0.85 for 2 quarters

Two-Year Tenancy Rate

≥ 80%

Failure: Below 80% at 24 months

Deployment Timeline

≤ 180 days

Failure: Occupancy not achieved in 180 days

Governance & Contribution

Split-Authority Model

The project enforces strict separation between Systems Architecture (Research & Development) and Executive Operations (Capital Procurement, Media, and Pilot Implementation).

This structure protects the intellectual integrity of the research from political and financial pressures.
