SECTION 04 // THRESHOLD REGISTRY[ER-PROP-01]

Operational Threshold Registry

Boundary Variance Detected · Review Point Prepared

Calculated outputs are continuously evaluated against deterministic operational boundaries. When an evaluated metric crosses a tolerance ceiling or floor, automated dispatch halts and routes to a defined human review point.

BOUNDARY RULE: PROP-THRESH-1STATUS: BREACHED
Emergency Repair Overrun Cap(+$2,350 vs target $1,500.00)
Rule: Variance (+$2,350) ≤ $1,500.00
TOLERANCE BREACH

Variance of +$2,350 exceeds the $1,500 threshold. Illustrative review point prepared.

Target: $1,500.00
BOUNDARY RULE: PROP-THRESH-2STATUS: PASSING
Portfolio Minimum Occupancy Floor(87.50% vs target 85.00%)
Rule: Occupancy (87.50%) ≥ 85.00%
WITHIN TOLERANCE

Occupancy at 87.50% satisfies the 85.00% portfolio target.

Target: 85.00%
