Source provenance
Every record carries a source_url + snapshot_id (sha256 hash of the scraped HTML at fetch time) + last_verified. 270 MB of raw HTML evidence stored. Verifiable, not vibes.
Native variant tracking
707 slots with 2–7 RTP variants the provider explicitly publishes (Play'n GO publishes 5 variants per slot, Yggdrasil publishes ranges). Most registries flatten this to a single number — we don't.
Weekly cron + meaningful diff
Mondays 06:00 UTC, all 15 providers re-scraped. Six trigger criteria detect material change (≥0.5% RTP shift, any new variant, ≥25 new slots, coverage status changes, etc.). Public changelog auto-fills. /rtp/changelog
