Complete. I've built the 13-week cash forecast and written the cash memo. Here's the summary:

**Covenant Status:** Week 5 breaches the $750K minimum, closing at $736K with a shortfall of $14K. Cash recovers to $816K in week 6.

**Key Findings:**
- Opening balance: $968K
- Closing balance week 13: $800K
- Net cash outflow: ($168K)
- Trough week: 5 (the only breach week)

**Files Created:**
- `output/cash13.json` — Script output with all calculated figures
- `output/cash13-note.md` — Cash memo with weekly forecast, covenant analysis, and levers to address the week 5 breach

The memo flags that vendor payments ($2.5M) and payroll ($464K) are the main drivers of the week 5 trough, and suggests accelerating collections and deferring vendor payments as options for the treasurer.
