I reviewed the register and wrote the note. Of 20 assumptions, 4 are flagged. The script's counts reconciled.

**Flagged**
- **A-09 Inventory turns** (Tomas Herrera): stale review, last reviewed 2025-03-14.
- **A-13 Line of credit interest rate** (Dana Whitfield): stale review, last reviewed 2025-06-02.
- **A-16 Merit increase**: no owner.
- **A-04 Average headcount**: the value moved from 23.00 to 23.75 in the Current version with no source. It feeds the Headcount driver, so it is the one that matters most for opex.

A further 4 assumptions changed value and have sources: A-01, A-03, A-07 and A-08. They are listed in the note but not flagged.

**The review date is 2026-01-01.** The skill dates reviews against that default unless told otherwise, and you didn't give another date. Today is 2026-10-03, so the real staleness picture is worse than this note shows. Many more assumptions would be past the 180-day threshold. If you want it dated to today, I can re-run with `--as-of 2026-10-03`.
