Done. I've generated the forecast change note reconciling the Prior and Current FY2026 forecasts.

**Summary of the EBITDA bridge:**

- **Prior EBITDA: $452K → Current EBITDA: $303K, a decline of ($149K) or (32.9%)**

The three drivers of change:

1. **Active customers** dropped by 2 across all 12 months (46 to 44), driving the largest EBITDA decline of **($133K)**
2. **Headcount** increased by 0.75 FTE over 9 months, adding **($54K)** in opex costs
3. **Gross margin** improved 40 basis points across all 12 months, partially offsetting with **$39K** of upside

The walk reconciles perfectly to the total EBITDA change. The note is in `output/drivers-note.md` with all figures sourced from the script's computed values.
