When no site code is found via Claude extraction or regex cascade,
the Lambda now checks the PO address against a cold-start cache of
verified-sites (normalized street + zip match). If still no match,
the PO is written to a new pending-site-review table for manual
verification against Payee Central.
The Claude extraction prompt now explicitly asks for site_code (the
Amazon facility code) and structured ship_to address fields (street,
city, state, zip). The site-extractor Lambda prefers these direct
fields when available, falling back to regex for older PO records.
Enable DynamoDB Streams on purchase-orders table and add a site-extractor
Lambda that extracts Amazon facility codes and addresses from PO ship-to
data, upserting them into a new verified-sites table. Includes a backfill
script for existing POs and upgrades existing Lambdas to arm64 + 60-day
log retention.
CDK stack with SES receipt rule, S3 bucket, email processor Lambda
(Claude-powered extraction), web UI Lambda with Function URL, and
DynamoDB for storage. Includes reprocessing script for missed emails.
