feat(postcodes/CZ): 2,695 Česká pošta PSČ codes (#1039)#1512
Merged
Conversation
Adds the full Czech 5-digit PSČ (poštovní směrovací číslo / postal code) list joined with okres (district) and obec (municipality) data from the 1nfinity84/PSC-Okres-Obec-OkresCZ mirror. Why --- Closes the CZ gap on issue #1039. The previously-tracked soit-sk/czech_republic_post_codes_2007 source shipped only a Perl scraper for the 2007 stamps DB and required Česká pošta b2b TLS access (blocked from this harness). 1nfinity84's mirror is a static JSON join requiring no scraping. Coverage -------- - 2,695 codes / 100% state FK - 77 of 90 CSC CZ states covered (76 districts + Praha capital city) State FK strategy ----------------- Direct district-name match against CSC's 76 okres entries plus a single alias 'Praha' -> 'Praha, Hlavní město' (CSC iso2 '10', the capital city which is administered separately from the surrounding Praha-východ/Praha-západ districts). For PSCs whose source value is an array (multiple districts share the same PSC), picks the first as primary state. Locality -------- Each record carries a locality_name derived from the source's psc_to_obec list. Parenthetical fragments like '(část)' (part of) or '(Praha 10)' are stripped for readability. License ------- 1nfinity84/PSC-Okres-Obec-OkresCZ: no formal LICENSE file. Upstream chain: Česká pošta + ČSÚ open lookups -> rotten77's SQL dump -> 1nfinity84's static JSON join. Tier 5 per #1039 license-tier policy. Each row: source: "ceska-posta-via-1nfinity84" Validation ---------- - python3 -m py_compile passes - 100% regex match (^\d{3}\s?\d{2}$) - 100% state_id valid + state.country_id == 58 + 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>

Summary
Only ships a Perl scraper for the 2007 stamps DB; would need to run scraper + fetch from Česká pošta b2b (memory: TLS handshake fails)Source
1nfinity84/PSC-Okres-Obec-OkresCZ—mapping_data.json(4 MB)Why this source (not soit-sk)
The previously-tracked
soit-sk/czech_republic_post_codes_2007shipped only a Perl scraper requiring Česká pošta b2b TLS access (blocked from this harness per memory). 1nfinity84's mirror is a static JSON join — no scraping needed, refresh by upstream re-publish.State FK strategy
Direct district-name match against CSC's 76 okres entries plus a single alias:
'Praha'→'Praha, Hlavní město'(CSC iso210, the capital city which is administered separately from the surroundingPraha-východ/Praha-západdistricts)For PSCs whose source value is an array (multiple districts share the same PSC), picks the first as primary state.
