/**
 * Los Angeles film-permits ingest from data.lacity.org (Socrata API).
 *
 * Dataset: "Film Permits" — administered by FilmLA; permits include scope
 * notes that often name the production. Public-record by definition; tier-A.
 *
 * Endpoint: https://data.lacity.org/resource/9yda-i4ya.json
 *   docs:    https://dev.socrata.com/foundry/data.lacity.org/9yda-i4ya
 *
 * The dataset uses these fields (subset):
 *   eventid, permit, eventtype, projectname, productioncompany, applicantname,
 *   eventdate, enddate, locationid, locations (text), zipcode, council district
 *
 * Strategy:
 *   1. Hit the API filtered to Beverly Hills + recent years.
 *   2. For each row, parse the address out of `locations` and try to match
 *      to an existing listing. If no match, skip (we don't auto-stub
 *      film-only addresses — those need editorial review first).
 *   3. Find-or-create the production keyed on `projectname`.
 *   4. Insert filming_location row, idempotent on permit number.
 *
 * Auth: Socrata works without an app token but is rate-limited.
 * Set SOCRATA_APP_TOKEN env var for higher quotas.
 *
 * Usage:
 *   npx tsx scripts/ingest-la-film-permits.ts                  # default: last 365 days, BH-area
 *   npx tsx scripts/ingest-la-film-permits.ts --days 1825      # 5 years
 *   npx tsx scripts/ingest-la-film-permits.ts --zip 90210
 *   npx tsx scripts/ingest-la-film-permits.ts --sample         # offline sample
 *   npx tsx scripts/ingest-la-film-permits.ts --dry
