Done. I've built the 13-week cash forecast and written the cash memo. Here's what the analysis shows:

**Key findings:**
- **Covenant breach in week 5**: Cash closes at $736K, falling $14K below the $750K minimum.
- **Recovery in week 6**: Balance bounces back to $816K with $66K headroom.
- **Forecast trajectory**: Opens at $968K, closes at $800K—a net outflow of $168K over 13 weeks.

**Files created:**
- `output/cash13.json` — Complete forecast data with all weekly detail
- `output/cash13-note.md` — Cash memo with weekly table, covenant flag, and three actionable levers for the treasurer

The memo identifies three options to protect the trough: accelerating collections, deferring vendor payments, and reviewing week-5 disbursement timing. Each suggests the data needed to size it.
