Recognises an unresolved many-to-many relationship

What it means

An N:M relationship left in the model. Its facts (dates, shares, roles) have nowhere to live, and they are usually requirements not yet captured.

How it is assessed

Flags the deficient case and passes the acceptable one. Deficient: Account N:M Party "is held by", with holder role and start date in nobody's attributes Acceptable: Account Holder associative entity with holder role and start date (`LOG-010`)
