INS-01 — A flood damages a building; insurance changes who bears part of the loss
Event — BLDG_CLIM_FLOOD_DAMAGE: a 100-year flood (severity quantile 0.99, authored canon) strikes a Class-A office property (global_buildings_v3, engine10, seed 42).
Starting state — the building owner (a REIT) holds the property with an authored business-interruption insurance relationship; the insurer carries the BI book.
What changed — the flood damages the foundation and shuts the building: structural damage −$5,358,657 (ClimateHazardModel, koprisk-served), NOI loss −$168,402,475 (RealEstateIncomeModel, FEMA HAZUS-MH closure canon). The authored BI conservation pair then fires.
Who bears the consequence — BUILDING_OWNER_REIT +$6,550,000 (BI claim received) · INSURER_BUSINESS_INTERRUPTION −$6,550,000 (BI claim paid) · sum $0 exactly. Business-interruption recovery transfers this portion of the modeled loss from owner to insurer. The owner's +$6.55M is NOT a total event gain — the same receipt charges the owner the physical damage and NOI loss above.
Key numbers — transfer pair ±$6,550,000 (conservation-exact); damage −$5.36M; NOI −$168.4M.
Boundary — INSURER_PROPERTY and TENANT_CORPORATE rows are UNRESOLVED_INPUTS (named fields); the equipment-origin variant (elevator) remains an AUTHORING_GAP.
Evidence status — VERIFIED_EXISTING; rerun on freeze commit c3229eed7ed268d9677ce2a7333ecd4417e5fa42,
