Some checks are pending
Deploy / deploy (push) Waiting to run
Generate a per-person weekly summary PDF at Thursday close and store it
alongside the CSV reports, plus a client-side admin download that rolls
orders up into item -> total quantity for bulk ordering.
- shared/pdf.py: build_weekly_summary_pdf() via fpdf2 (pure-Python,
ARM64-safe; first non-boto3 layer dep). Per-person employee -> item ->
quantity, no pricing.
- aggregate_orders: write reports/{week}/weekly-summary-{week}.pdf
(application/pdf) and stamp weekly_summary_pdf_s3_key on the SUMMARY.
No new IAM (existing S3CrudPolicy). No email/Slack delivery.
- generate_form.py: "Download order list" admin button aggregates the
loaded week's orders into an item->qty CSV (no per-employee breakdown,
no prices) via a Blob download. Works for open weeks too.
- Tests: tests/test_pdf.py; aggregate happy-path now asserts 3 S3
uploads + the pdf key.
- README updated.
