Scryway

A quiet place to study several contemplative practices side by side: tarot, the I Ching, runes, astrology, remote-viewing and Zener practice with honest scoring, meditation and dream work. Every session goes into a private journal.

The idea

Scryway grew out of KnowTarot. Its reading engine, journal and offline foundations became the first module of a broader platform, where each practice is a module with its own engine, texts and scoring, and all of them share one account and one journal.

What I built

Honest randomness. Casts and draws use the browser's cryptographic random source. The I Ching simulates the real odds of three coins or of yarrow stalks (changing yin 6.3%, changing yang 18.8%), and says which it is doing.
Perception practice that can't be gamed. Remote-viewing targets are assigned and kept on the server until the session is locked, results are compared with chance, and a ranked mode uses an Elo-style rating.
Real astronomy. Natal charts are calculated, not invented, by a separate service I wrote around the Swiss Ephemeris, published as open source under its AGPL licence. Every chart setting is stated and saved with the chart.
A private journal. Every session from every practice lands in one journal, with optional encryption of entries in the browser.
Texts. A library of sacred and classical texts, with the source and rights of each one listed.

I Ching casting page with three casting methods and their odds — The I Ching page states the probabilities each casting method uses.

Hard parts

Many practices, one product. A module structure lets each practice keep its own logic while sharing accounts, the journal, the design system and the test harness.
Licensing. The Swiss Ephemeris is dual-licensed. Running it as a separate open-source service keeps the AGPL obligations clear and the main app's code separate.
Pace with quality. About 130 commits in the first nine days, with unit tests and browser tests, including accessibility checks, from the start.

Natal chart form with birth date, time, place and chart settings — Natal charts work without an account; birth details stay in the browser unless the reader signs in.

Status
