Complete. I've generated the 13-week cash forecast with covenant flagging and the cash memo.

**Summary:**
- **Opening balance:** $968K
- **Week 13 closing:** $800K  
- **Trough:** Week 5 at $736K, a breach of ($14K) below the $750K minimum
- **Recovery:** Week 6
- **Net cash flow:** ($168K) over the horizon

The forecast shows a single-week covenant breach in week 5. Both recovery levers—accelerating collections and deferring vendor payments—must move by week 4 to clear the breach. The memo and detailed weekly table are in `output/cash13-note.md` with all figures sourced from the verified script output.
