* Add CI workflow and apply ruff formatting
* Disable cdk synth — email_processor uses pre-built package dir
The email_processor Lambda bundles deps into a gitignored package/
directory. cdk synth fails in CI without a build step to recreate it.
Disabling until packaging is standardized.
* Use CDK BundlingOptions for email_processor Lambda packaging
Replaces the pre-built gitignored package/ directory with CDK's
built-in bundling. Deps are now installed inside a Docker container
during cdk synth, so the build works identically locally and in CI.
Re-enables run-cdk-synth in the CI workflow.
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.
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.
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.
