Cardology One-Line Meaning Interface

What it does

The One-Line Meaning Interface turns deterministic Cardology facts into a compact answer that can expand into number, suit, planet, position, profile, year, source, and provenance layers.

It keeps calculation and interpretation separate:

• the local Cardology CLI determines the facts
• the one-line interface formats and layers them
• downstream UI/RAG systems can consume the JSON contract

Why I built it

The larger product is a birthday-generated Blueprint Vault. It needs a small, reliable kernel that can answer questions like:

cardology line 1991-02-17 today
cardology ask 1991-02-17 "what should I focus on today?"
cardology ask 1991-02-17 "what is age 35 about?" --sources

The key idea: a single line should be useful immediately, but every claim should be expandable and auditable.

How it works

The prototype calls the Cardology source layer, loads the compiled birthday repository when available, and emits a structured JSON payload.

Core artifact:

scripts/cardology-one-line-interface.ts

Fixture output:

examples/cardology-rag-blueprint-engine/fixtures/1991-02-17/one-line-2026-05-17.json

CLI output

1991-02-17 · 8♦ The Money Powerhouse · age 35 on 2026-05-17 · Venus puts 8♠ The Truth Power + 5♦ The Money Wanderer in play: Power used with grace. A change in what you value, possibly through love or aesthetic taste shifting.

What shipped

• One-line output for a birthdate and target date.
• JSON output with deterministic facts and provenance.
• Layers for number, suit, planet, position, profile, year, and source context.
• A schema for downstream consumers.
• A fixture for 1991-02-17 with birth card 8♦ and PRC 5♣.

What I learned

The one-line interface is the right primitive. A dense product can still feel simple if the first response is compressed and the depth is available on demand.

Next version

Wrap the prototype in a friendlier command surface and connect it directly to the Blueprint Vault Command Center UI.
