What were the conditions and hazards at this site? Signed.
Property condition, valuation-input and disclosure disputes turn on what the conditions and hazards at a site actually were on a date: was the drainage tested in the rain the inspector claims, was the flood exposure disclosed as it stood at settlement? Screenshots and after-the-fact letters do not survive scrutiny. This page returns one signed, independently re-verifiable record of the named public weather forecast and flood hazard sources for a property location, and every reading Dynamic Feed serves is archived, so what the sources said at time T stays re-checkable years later for inspection reports and climate-risk files.
A signed record of the site, right now.
Enter the property location, and optionally its coordinates for a precise hazard read. Dynamic Feed records the daily weather forecast from named public sources plus the modelled flood hazard for the nearest river cell, and returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you.

Property disputes are decided on records.
When a condition report, a valuation input or a disclosure statement is challenged, the question is what the weather and hazard exposure at the site actually were on the day, because that is what an inspection, a climate-risk file or a disclosure obligation rests on. A weather app screenshot or a hazard note typed up later is one party's own word. A contemporaneous record from an independent witness, signed at the moment, carrying its named source and observation time, and verifiable years later against a published key, is corroboration any party can test. Our records work for buyers, sellers, agents, valuers and inspectors alike: anyone can re-check them, and the archived reading for time T does not change when the dispute does.
Evidence, not a valuation ruling.
Dynamic Feed is a neutral witness, not a valuer, surveyor, insurer or adviser. This receipt is an advisory record of what public sources reported for the location at that moment. It does not value the property, does not rate its climate risk, and does not discharge any disclosure duty; the flood hazard layer is modelled river-discharge guidance, not a flood warning, and disclosure laws and contract terms vary by jurisdiction and product, so the interpretation stays with your people. It is one input beside the party's own records. Advisory evidence, tamper-evident not a certification or compliance ruling, zero personal data, and not legal advice.
