The AI drafts the appetite. Jordan Lee, the underwriter, approves or changes every draft. The EPL (employment practices liability) cover asked for is the policy line these drafts price.

Write 96.0% confidence that the underwriter agrees

Retail is an eligible class, with 31 FTE and no reported EPL claims or planned layoffs. No referral triggers or document issues are reported.
