Tarot

The Tarot engine.

A standalone divination surface that doesn't need ephemeris or birth data. Tarot draws use a seedable PRNG so any draw is reproducible from its seed — useful for shareable readings, saved reports, and deterministic tests. Pairs with a 4-cycle biorhythm calculator and a lunar-phase tone descriptor.

  • Rider-Waite-Smith 1909 deck — all 78 cards, reproducible draws given a seed
  • Four spreads: single, three-card, nine-card, classic Celtic Cross
  • Yes / no / uncertain verdicts gated on card confidence
  • Biorhythm — physical (23d), emotional (28d), intellectual (33d), spiritual (53d)
  • Lunar phase tone descriptor — 8 named phases of the synodic month
  • All 78 cards ship with upright + reversed paragraphs; Major Arcana paraphrased from Waite-Smith, Minor Arcana engineer-authored from tradition (every card carries a content_origin tag)
