   "what_happened": "The Northern Liberty Market opened in 1875 as a public market and operated until 1963, when it closed due to supermarket pressure. After closure, the site hosted the National Historical Wax Museum from 1964 to 1975, after which the building was demolished in 1985. Today the location contains the CityVista condominiums with a Safeway supermarket and other ground\u2011floor businesses.",
   "why": "The record attributes the 1963 closure to competition from supermarkets, indicating anchor loss due to retail pressure. Subsequent demolition followed the wax museum\u2019s departure, reflecting reuse pressures rather than debt or environmental factors.",
   "where_it_stands": "The site is currently operating as a mixed\u2011use development (CityVista condos with Safeway retail), though the record does not name a present owner.",
   "for_a_planner": [
    "Precedent: conversion of a historic market to residential\u2011retail mixed use (CityVista).",
    "Policy tools: the site\u2019s strategy is listed as \"redevelop\" and new uses include housing and retail.",

    "Site size and parcel boundaries are not provided in the record.",

   "risks_and_unknowns": [
    "Missing current owner and legal entity controlling the site.",
    "No data on parcel size, exact boundaries, or subdivision layout.",
    "Absence of context\u2011layer information (flood risk, transit proximity, environmental constraints).",
