feat(postcodes/AX): 37 Åland Islands codes (#1039)#1514
Merged
Conversation
Adds Åland Islands' 37 postal codes from Posti.fi's PCF DAT (Åland-region records, FI200), shipping to AX.json under the separate CSC country code AX (Åland Islands, country_id=2). Why --- Closes the AX gap on issue #1039. Posti's PCF file carries Åland records under region FI200 / Ahvenanmaa. Companion FI importer skips these so they ship to AX as a separate country. Coverage -------- - 37 codes / 100% state FK - All 16 Åland municipalities covered State FK strategy ----------------- Direct municipality-name match against CSC's 16 AX states (Swedish form). One alias for Finnish->Swedish drift: 'Maarianhamina' -> 'Mariehamn' (the canonical Swedish form; Åland's only official language is Swedish). Source pipeline --------------- Same URL probe as FI importer (PCF_<YYYYMMDD>.dat, ~30-day-back HEAD probe, ISO-8859-1 fixed-width parse), filtered to FI200 region. License ------- Source: Posti.fi PCF (Tier 5 per #1039 license-tier policy). Each row: source: "posti-fi-pcf" Validation ---------- - python3 -m py_compile passes - 100% regex match (^(?:FI)*\d{5}$) - 100% state_id valid + state.country_id == 2 + state_code agrees - No auto-managed fields (id, created_at, updated_at, flag) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
