What did the forecast say? Keep the record.
Delay claims, event cancellations, "we relied on the forecast" defences: they all turn on what the forecast actually said before the event, and forecasts are overwritten the moment they update. Dynamic Feed issues a signed, independently re-verifiable receipt of today's multi-model forecast for any location, and archives a daily snapshot for 20 major cities and ports in a permanent, append-only archive. When the dispute arrives, the record already exists.
Today's forecast, signed and kept.
Enter a city. Dynamic Feed records the 7-day multi-model forecast (ECMWF, GFS, ICON and GEM compared per day, with an honest confidence label from their spread) and returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you.

Forecasts vanish. Disputes don't.
A forecast is the only weather record that disappears by design: every update overwrites the last one, and six months later nobody can show what was predicted on the day a crew was stood down, an event was cancelled or a sailing was delayed. A screenshot proves little. A record signed at the moment, carrying its sources and model spread, and verifiable years later against a published key, is the version that survives scrutiny. Our records work against us just as well as they work for you: anyone can re-check them, including the other side.
A record of the forecast, not a promise about the weather.
Dynamic Feed is a neutral witness, not a forecaster and not an adjudicator. This receipt does not assert that the forecast was right, does not decide whether reliance on it was reasonable, and does not replace the official national forecast a contract may name. Advisory evidence, tamper-evident not tamper-proof, zero personal data, and not legal advice.
Every decision, with the forecast it relied on.
Ops software can mint a signed forecast receipt at every weather-based call automatically, keyless to try, self-serve to scale.
