Kalshi NHIGH / NLOW settlement station whitelist.

Kalshi’s NHIGH (daily high temperature) and NLOW (daily low temperature) markets settle against the NWS CLI report for a SPECIFIC station — NOT the airport you’d assume. Common surprises:

• NYC settles against KNYC (Central Park), NOT KLGA or KJFK.
• Chicago settles against KMDW (Midway), NOT KORD (O’Hare).
• DC settles against KDCA (Reagan National), NOT KIAD or KBWI.

Citations are URLs to the Kalshi contract specification pages where the issuer documents the settlement station. These are committed to the repo so the v0.14.1 parity gate cannot regress on station identity.

This is parity-critical. A wrong station mapping silently settles research against the wrong data; the model “works” but acts on garbage. The contract test in this module asserts no entry resolves to {KLGA, KJFK, KORD, KIAD, KBWI} — the most common wrong answers.

City ticker → (settlement station ICAO, citation URL). The 20-city Kalshi NHIGH/NLOW universe, verified against the live Kalshi series API (GET /trade-api/v2/series?category=Climate and Weather + per-series settlement_sources). The v0.1.0 scope doc listed 21 cities, four of which (DTW/CVG/BNA/SLC) never had live markets — every series probe 404s — and it missed NOLA/OKC/SATX, which do. The citation URL is the live Kalshi contract page; if the issuer renames the city ticker the citation URL still resolves and the test stays green.

The remaining cities (Honolulu, Anchorage, etc.) defer to future international expansion.

The known-WRONG stations that must NEVER appear in KALSHI_SETTLEMENT_STATIONS values. Contract test test_no_wrong_stations enforces this.
