Class: Matrix

ATT&CK Matrices define the structural layout and organization of tactics and techniques within each ATT&CK domain. The matrix arranges tactics as columns and techniques (with sub-techniques nested beneath parents) as rows, providing a comprehensive visual map of adversary behavior within a domain.

Each ATT&CK domain has exactly one Matrix object. The tactic_refs property contains an ordered list of x-mitre-tactic STIX IDs that defines the left-to-right display order of columns in the ATT&CK matrix. The matrix does not directly enumerate techniques — technique-to-tactic associations are captured via kill_chain_phases on the Technique objects.
