# Numerology

`/numerology` is the pack page for the Pythagorean engine (`lib/numerology`). It is the first system in `ring-config.evolvement.systems` and the usual Life Path voter on the Knowledge Council.

This is **not** Destiny Matrix and **not** name-code. Those have their own pages. Numerology here means date reductions (and, when a full birth name is present, Expression / Soul Urge / Personality as part of the same Pythagorean family). Digital anthroponymics wraps the same letter tables as **labeled FIO layers** and votes separately.

## What the page shows

- Life Path from birth date, with reduction steps (`showMath`).
- Personal Day for the selected civil date.
- Universal Day (date only).
- Optional Expression when a full name exists.
- Ethics / education disclaimer from pack copy, not a prediction.

Cyrillic letter values live in `lib/numerology/alphabets.ts` (UK and RU positional tables). The intro deck uses the pack ANNA / АННА example: Latin ANNA reduces to 3, Ukrainian/Russian АННА to 5. Chaldean for Cyrillic is a **labeled transliteration** onto Latin 1-8 with compound preservation, documented in pack ethics text. It is not silent Latinization.

## Council vote

Ready numerology votes from **Personal Day** into `dayFamily` for topic `today_practice`, from **Personal Month** into `week_focus`, and from **Life Path** into `decision_style`. Confidence `numerologyReady` is `0.86` in `council-mappings.json` (exact date math, interpretive family overlay). Master numbers 11, 22, 33 keep their labels in the chart; family overlay maps 11 to reflect, 22 to build, 33 to care.

## Meanings

`evolvement.meanings.numerology.lifePath.{1-9,11,22,33}` and `numerology.day.{...}` plus `moon.{eight phases}`. UI translates keys; English `text` remains the fallback. UK/RU currently repeat English until review.

Tests: pack `lib/numerology/__tests__/cyrillic.test.ts` plus the composed engine suite. Gold vector used in this campaign: birth date `1990-08-18` for Life Path checks.

> **Warning**
> Do not describe Personal Day as chance, a spin, or fortune. It is a precomputed cycle digit from the civil date and the birth date.
