Symbol gamma
What this part means
an explicit gate on the edge — a test, a validation check, or a human approval — that must pass before the transition is permitted.
Its job in the formula
gamma is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it
where each node v V is either a deterministic function or an invocation of some policy , and is an explicit gate on the edge — a test, a validation check, or a human approval — that must pass before the transition is permitted.
The passage around this formula
where each node v V is either a deterministic function or an invocation of some policy , and is an explicit gate on the edge — a test, a validation check, or a human approval — that must pass before the transition is permitted. That is the structural reason human approval is a first-class primitive in this pattern rather than a wrapper bolted around it from outside: approval is just one kind of , attached to one particular edge, rather than a blanket condition on the whole run.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
