A parametric flood policy fires on a NOAA gauge.

Broker submits an AL3 Homeowner Application against a 1,840 sqft single-family at APN 044-238-021. The form arrives as a typed object with 142 populated fields, schema-validated against ACORD XML AL3 v2.7.0 — no OCR pass, no human re-keying.

TerraOS returns the Parcel + Property + Unit triad signed under schema v1: year built 1976, replacement cost basis $740,000 (Marshall & Swift class D rev 2026-Q1), roof age 4y, sub-meter:on. No address geocoding step — the parcel APN is the join key.

Base rate from ISO HO-3 2024 territory 412, multiplied through the wind-mitigation credits (FBC 1802.1.3.2), construction class (Frame ISO 1), and protection class (PC-3). Indicated annual premium: $2,140.27. Each factor is a row in the receipt, pinned to manual page and effective date.

Rider triggers when NOAA CO-OPS station 9410230 (La Jolla, X124 internal id) reports a 6-minute verified water level above 12.4 ft MLLW for 3 consecutive readings. Payout: $50,000 within 72 hours of trigger. The oracle is the public NOAA feed — not an adjuster.

Cession message in ACORD ReIM v2.34 routes $40,000 of the $50,000 parametric limit to treaty TR-2026-PFLOOD-CA at price 6.8% rate-on-line. Slip is signed by the lead market; following markets co-sign via FROST 3-of-5. Treaty effective 2026-01-01 to 2026-12-31.

Property sits in FEMA flood zone AE (BFE 11 ft). NFIP SFIP Dwelling Form covers indemnity to $250,000; the parametric rider sits as supplemental rapid-pay liquidity on top. The two policies are linked by the same TerraOS parcel id — one source of truth for both.

Effective 2026-05-07T17:22:14Z, the exact moment ISO 20022 pacs.008 cleared the wire. Declarations page is a 38-line JSON object signed Ed25519 by the carrier; coverage starts when settlement is witnessed, not when the agent fills a form.

Daemon polls NOAA CO-OPS at the published 6-minute cadence and writes one micro-receipt per reading. 87,600 reads/year at 0.00041 J each = 35.9 J/yr of standing watch. No claim arrives until the predicate fires; if it fires, the payout receipt is the claim form.
