Replaces extraction prompt with domain-specific rules: trade
classification taxonomy (23 categories), site_code skip list,
zip padding, revision email type, and structured extraction for
fiscal_year, trade, and coupa_category.
Handler changes:
- New "revision" email type overwrites existing PO via put_item
- enrich_parsed() adds top-level state, ship_to_raw, data_source
- pad_zip() zero-pads short zip codes (e.g., "7001" → "07001")
- Removed invoice_total/invoice_count (Payee Central only)
Web UI: added revision badge, new detail fields (site code, state,
trade, fiscal year, coupa category, data source), line item table
now shows Qty/Unit/Price columns, list view shows Site and Trade.
CDK: fixed StreamViewType to match deployed table (NEW_IMAGE).
README: documented PO record schema and revision flow.
* Add CI/CD pipeline and fix stack name to kebab-case
CodePipeline V2 (po-ingest-pipeline) triggers CodeBuild on push
to main, running cdk deploy via buildspec.yml. Stack name changed
from PoIngestStack to po-ingest to match naming conventions.
* Add RETAIN policy to Secrets Manager secret
Prevents the Anthropic API key from being deleted if the stack
is ever removed. Matches the RETAIN policy on all other stateful
resources (DynamoDB tables, S3 bucket).
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.
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.
Pin existing CloudFormation stack name via stack_name property so
the live stack is not affected. Construct ID now follows the org
kebab-case standard.
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.
