How the roll-up gate works
This tool grades every domain's model against the six things a machine needs to check it, then rolls the portfolio up to its weakest domain. It reads 6 domains and rolls them into one verdict — the worst, never the average — then a gate that can only make it worse.
The 6 domains
A domain with 15 or more entity types whose closed-value-set or disjointness lever is not fully MODELED is forced to UNMODELED however high its coverage — at that size an undeclared value set or overlap is where the contradictions come from. One UNMODELED domain overrides the mean coverage, so the whole portfolio reads NO MODEL.
Why: Mean coverage across the six domains is 88% and two are fully MODELED — on the average this portfolio looks close. But three domains read UNMODELED: Billing and Fulfilment cross the entity-scale gate with a modeling lever still PARTIAL (at 83% and 92% coverage), and Inventory has an undeclared identity rule with the gate quiet. One UNMODELED domain forces NO MODEL, so the mean decides nothing.
No single domain is the crisis — the clustering is. The roll-up takes the worst, the gate escalates when trouble compounds, and it names the one thing to fix first. Grades a domain model you describe. A working aid, not legal, security, or compliance advice, and not an audit or a certification. It never scores or ranks people — MODEL HOLDS means these six things are written down, not that they are correct.
