Why Directed Acyclic Graphs?

A DAG is a directed graph with no directed cycles. In legal reasoning, that means no circular support is structurally possible: every claim must be supported by evidence through explicit, one-way inferential links. This is not a stylistic choice — it is a logical constraint that makes incomplete reasoning immediately visible.

No circular logic — by design

DAGs enforce “A supports B” without letting B secretly support A. The moment a cycle is attempted the structure breaks — before the argument reaches a judge or examiner.

Complete element coverage

You cannot hide a missing element. Every legal requirement must have at least one incoming evidentiary arrow. Empty nodes are visible immediately, not at trial.

Stress-testable proof chains

Counter-inferences and attacks are mapped directly onto the weakest inferential links. You see exactly where your argument can be broken — and fix it first.
