Signatories with models on the register

Signing the Code and publishing a training-data summary are different acts. This is where the two can be compared.

Signatories this register does not yet track

These companies signed the Code but have no model on the register, so it says nothing about whether they have published a training-data summary. That is a gap in coverage, not a finding about them — and stating it is the difference between a sample and a reference.
