Permits Checklist Feature Implementation Plan

Project Overview

Goal: Implement a comprehensive permits checklist system for loan files that allows users to:

  1. Extract permit requirements from permit certificate documents using AI
  2. Display a checklist of required permits in the loan file UI
  3. Upload documents to satisfy specific permit requirements
  4. Eventually have AI verify that uploaded documents cover the required permits
