"""
GovBridge India — World No. 1 Multi-Source Ingestion Engine (v4.0)
===================================================================
STRATEGY: Instead of fragile Tor+Playwright scraping of a React SPA,
we use MULTIPLE reliable data sources that return structured data:

  Source 1: MyScheme.gov.in Playwright (NO Tor — direct headless)
            Uses proper wait_for_selector, intercepts XHR API calls
  Source 2: PIB RSS Feed — government press releases
  Source 3: India.gov.in open data pages

PROTECTIONS:
  - NEVER overwrites AI-enriched records (checks is_verified flag)
  - Logs every run to bot_run_log table
  - Deduplicates by title before upserting
  - All summaries must be >50 chars (no placeholders)

Runs daily via GitHub Actions (02_data_ingestion_bot.yml).
