The assumption register review is complete. I've written a register review to `output/register-note.md` that identifies:

**Key findings:**
- **2 stale reviews** (180+ days since last review): Inventory turns (293 days) owned by Tomas Herrera, and Line of credit interest rate (213 days) owned by Dana Whitfield
- **1 assumption with no owner**: Merit increase
- **1 unsourced change**: Average headcount increased from 23.00 to 23.75 FTE, with no source recorded—and this change feeds the headcount driver

**Changed values (5 total):** Active customers down to 44, Gross margin up to 26.6%, Average headcount up to 23.75, List price increase up to 4.5%, and Days sales outstanding up to 47.

The review and raw data are in the `output/` folder.
