Divinatory OS

A symbolic operating system for divinatory practice
2026
software / correspondence graph

A versioned correspondence graph as kernel, divinatory methods as programs that return addresses into it, and an append-only ledger of readings and outcomes as memory.

Symbol, address, ledger: three layers over one address space.
Symbol, address, ledger: three layers over one address space.

Three layers, one address space

  • kernel: correspondence graph, addresses, typed cited edges. Deterministic, model-free.
  • methods: divinatory programs. Question plus seed returns addresses. Replayable.
  • ledger: append-only draws, interpretations, outcomes. Never merged, never edited.

Status

The core is complete and every apparatus invariant holds with tests: 65 of them. A cast produces addresses from a recorded seed, the draw is fsynced before anything can interpret it, and replay re-derives it from the ledger alone.

Seeded so far: I Ching only: 72 symbols, 512 cited edges. Tarot and astrology are designed for and not yet loaded.

What reads from it

Order of the Meridian reads its spirit corpus from here in place: 68 spirits transcribed from Reginald Scot, The Discovery of Witchcraft (1665). Nothing is copied across, so no citation can drift from what it cites.
