Direction

iitx.direction

The two temporal directions of causal analysis.

Every quantity that exists on both temporal sides — repertoires, integrated information, purviews — is one function taking a :class:Direction, so cause and effect mirror each other structurally rather than by parallel code paths (docs/glossary.md, naming rule 1).

Direction

Bases: Enum

Temporal direction of a causal quantity.

CAUSE looks one step into the past (what states could have led here); EFFECT looks one step into the future (what states this leads to). A direction is static configuration — pass it as a Python value, never as a traced array.
