Clause 5

# The methods dimension

Four method families and a reading rule. None of the families is a maturity level, and the public preview does not carry the descriptor wording.

A method is how the system does something. The four families cover rules and optimisation, symbolic reasoning, learned models and combinations. The pages set out what each family implies for the inventory, the evidence and the change record.
