GET the record bytes, SHA-256 them, and call SnapshotAnchor.isAnchored(sha256) on Flare - the anchored record is the one to settle on

Flags are attached beside the anchored record and are not part of its bytes; the record's extremes are unchanged. A suspect extreme is usable but worth checking against the raw text (extremes.*.reasons); a bad report is physically impossible and excludingBad shows the extremes without it.

Settlement source: the METAR-derived station-day record for OPKC for the contract date (station-local calendar day), as published at https://weathermarket.io/station/OPKC/2026-10-18 with every observation used, the finality status and the Flare anchor of the record. The daily value is the extreme over the hourly and special METAR reports in that day; a short-lived peak between reports may be missed. If the record is not final and settleable by the resolution deadline, the market is flagged for review.
Station-day record: the daily extremes over every METAR observation (hourly plus special reports) received for the station's local calendar day - local midnight to local midnight, daylight saving applied. Temperatures are whole degrees Celsius as reported in METAR; a short-lived peak between reports can be missed. This is not a model or an aggregate - every value points at the report that produced it, and every report in the day is listed verbatim.
The settlement value is the daily maximum (or minimum) of this record once it is final: the local day has ended and the 3-hour correction hold has passed. 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).
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.
