A day whose longest gap between reports exceeds the station's normal interval plus 30 minutes is final but flagged not settleable - a market should treat it as a review case. Once final, the canonical record bytes are hashed (SHA-256) and the hash is written to the SnapshotAnchor contract on Flare; the anchored record is the settlement record even if reports change afterwards (matchesCurrent then reads false). US markets usually settle on the official NWS CLI value instead - see the NWS CLI archive for this station; both values are shown side by side.","verify":["Every METAR in the day is listed with its raw text; compare it with the independent archives linked under links.external (IEM ASOS archive, Ogimet).","GET links.record for the canonical record bytes, SHA-256 them and compare with anchor.sha256; call SnapshotAnchor.isAnchored(sha256) on Flare (anchor.contract, anchor.chainId) to confirm the hash is on-chain. anchor.explorer opens the anchoring transaction.","Permalink pattern for market rules: https://weathermarket.io/station/KIAH/YYYY-MM-DD (HTML) and https://weathermarket.io/api/station/KIAH/YYYY-MM-DD (JSON)."],"citation":"Settlement source: the METAR-derived station-day record for KIAH for the contract date (station-local calendar day), as published at https://weathermarket.io/station/KIAH/YYYY-MM-DD with every observation used, the finality status and the Flare anchor of the record.
