Middle authority
They diagnose. They never grant permission.
The engines receive already-computed truth from the Journal, Weekly Summary, EV Scorecard, and Compliance Panel and turn it into structural intelligence. Their role is middle authority: above raw calculation, below hard governance. They change the operator's review posture — continue, watch, repair, or compress — but no diagnostic verdict ever overrides the Gate Map or the brake rules.
- If a diagnostic reads constructive but the Gate Map says Floor or below, the gate wins.
- Diagnostic optimism never unlocks capital during defensive gates.
