Function tripped 

pub fn tripped() -> bool

Whether the current boolean OR the current element has exceeded its escalation budget. Checked at loop boundaries in the arrangement AND inside the per-point retriangulation loop so the bail is timely and graceful. Once the per-element budget is blown, every subsequent boolean the element issues trips immediately (its COUNT resets per begin, but ELEM_COUNT does not), so the element’s remaining cuts bail to the #635 AABB fallback.
