The stack cut

Which layers this engine leans on

The Sub-Brand Gate

Status: published before it is cleared

The full gate

Chartered, not launched · renamed from OceanTN

BlueTN

The chartered sub-brand for this engine. It has not launched.

No AI body anywhere publishes the conditions under which it will and will not launch something. Here is exactly what this sub-brand must clear.

A named full-time owner who is not the founder

A Milk line covering ≥60% of first-year cost

A Mountain charter

A coherence mechanism

An independence audit
