Run this regex audit (Python/Node):

import re

gbp_addr = "123 Main St, Chicago, IL 60601"

lsa_addr = "123 Main Street, Chicago, IL 60601"

if re.sub(r'\s+', ' ', gbp_addr.strip()) != re.sub(r'\s+', ' ', lsa_addr.strip()):

print(" MISMATCH - Fix before appeal")

Common fails: "St." vs "Street", extra spaces, comma placement.
