* Merge workorder-ingest pipeline into unified repo
Move PO lambdas under lambdas/po/, add WO pipeline under lambdas/wo/.
Two independent CloudFormation stacks in one CDK app. Fix WO stack
compliance: ARM64 architecture, 60-day log retention, aarch64 bundling,
RETAIN on Anthropic secret. Remove stale CodePipeline buildspec.
* Fix test_local.py import path and remove dead shared/models.py
test_local.py referenced the old lambdas/email_processor path. Updated
to lambdas/wo/email_processor. Removed shared/ directory entirely as
nothing imports from it.
* Escape HTML in both web UI dashboards to prevent XSS
Both Function URLs are public (auth_type=NONE) and render
email-derived content via f-strings. Attacker-crafted emails
could inject scripts. Added html.escape() on all interpolated
values in both PO and WO dashboards.
* Add pagination to WO web UI scan
get_work_orders() only fetched the first 1MB page from DynamoDB.
Loop on LastEvaluatedKey to match the PO web UI pattern.
* Fix esc(None) TypeError and javascript: scheme in PO web UI
Coerce supplier name through `or ""` before escaping to handle
nested None from DynamoDB. Add scheme allowlist on view_order_url
to block javascript:/data: hrefs from LLM-extracted URLs.
* Fix WO render_badge None guard, updated_at slice, and backfill path
Add null guard to WO render_badge matching the PO version. Use
`or ""` before slicing updated_at to handle explicit None values.
Fix backfill_sites.py sys.path to use new lambdas/po/site_extractor.
* Harden WO web UI and fix JS-context XSS in both dashboards
- Use json.dumps for onclick URLs to prevent JS string breakout
- Add .lower() to WO render_badge color lookup matching PO pattern
- Add pagination to get_comments query
- Cap get_work_orders to 500 results matching PO pattern
* Apply ruff formatting to web UI handlers
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).
