What it is.
A list of events with dates goes in; they are put in order, the interval between neighbours is computed, a date that cannot be read is refused, and every event that carries no date is named.
A year alone reads as the first of January, and the card says so.
Its laws, written into the card.
Order by date, never by the order written.
An undated event is named, not placed.

In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →
