Done. I've built the 13-week cash forecast, flagged the covenant breach, and written the cash memo.

**Key findings:**
- Cash opens at $968K and closes week 13 at $800K, declining ($168K) over the horizon.
- Week 5 breaches the $750K covenant minimum, closing at $736K with ($14K) headroom—the trough of the forecast.
- Cash recovers to the minimum in week 6 and maintains headroom through week 13.

The memo flags four levers the treasurer can use to improve week 5: accelerating collections, deferring vendor payments, reducing capex in weeks 4 or 10, or increasing other receipts. Both the forecast data (cash13.json) and memo (cash13-note.md) are in output/.
