Branching that reads.

Amount threshold routes correctly — every time.

$12,500 exceeds $5k. The request routes to human approvers.

amount >= $5,000
Yes — Approval Lane
Requires Approvals
Finance Review
Manager Approval
Security Check
No — Auto-Approve
Auto-Approved

Requests under $5,000 skip human review.

Parallel approvals.

Finance + Manager + Security — simultaneously.
