Done. The 13-week cash forecast, covenant flag, and cash memo are ready:

**Key findings:**
- Cash opens at $968K and closes week 13 at $800K with a net outflow of ($168K).
- **Covenant breach in week 5**: balance drops to $736K, falling ($14K) below the $750K minimum.
- **Trough: week 5 (2026-02-02)** with only ($14K) headroom.
- **Recovery: week 6** when collections lift the balance to $816K.
- Week 13 closes with $50K headroom.

Both files are in `output/`:
- `cash13.json` – script output with all line-item detail
- `cash13-note.md` – the cash memo with the weekly table, covenant status, and actionable levers for the treasurer

The memo suggests four options to lift the trough: accelerate week 1–4 collections, defer week 5–6 vendor payments, review week 5 payroll timing, and defer discretionary capex.
