Symbol Δ

A(Δ)=I(Δ)∧P(Δ)∧V(Δ)∧H(Δ),A(\Delta)=I(\Delta)\land P(\Delta)\land V(\Delta)\land H(\Delta),
Δ\Delta

What this part means

Δ is an argument of the function-like quantity on the left; its role is set by that function’s stated inputs.

The passage around this formula

This guide models acceptance as A(Δ)=I(Δ)∧P(Δ)∧V(Δ)∧H(Δ)A(\Delta)=I(\Delta)\land P(\Delta)\land V(\Delta)\land H(\Delta). where a proposed change Δ\Delta must satisfy intent I , policy P , executable verification V , and required human authorization H . Codex can contribute to all four. It should not be the sole authority for any of them.
