The Invisible Patient: Structural Inevitability, Perception Constraints, and Institutional Blindness

The Invisible Patient: Structural Inevitability, Perception Constraints, and Institutional Blindness is a sharpened and expanded analysis of why people experiencing homelessness become systematically misrecognized within emergency departments and broader governance systems. The paper reframes non‑recognition not as a cultural or professional failure but as an architectural inevitability produced by structural latency, perception constraints, and institutional processing limits. It formalizes key SR primitives—including Structural Latency and the Perception Constraint Principle—and introduces an Interruption Architecture that identifies precise, auditable breakpoints where the misrecognition pipeline can be disrupted. Through empirical grounding, operational mechanisms, and a canonical synthesis paragraph, the paper positions the Invisible Patient as a predictable outcome of modern systems operating at the edge of their perceptual capacity.
