Complete! I've built the FY2025 revenue bridge for InterStationary and written the commentary note.

**Key findings:**
- Revenue essentially flat year-over-year: $11.2M → $11.2M, a decline of just ($5K)
- Major headwinds: Lost 4 customers totaling ($1.3M) in revenue, plus declines from 11 existing customers of ($443K)
- Key offset: 23 customers expanded by $1.2M in upsells, and 6 new customers added $463K
- Harbor Freight Partners was the strongest upsell at $148K; Fenwick Legal's loss of $686K was the biggest single drag

**Output files:**
- `output/bridge.json` — Detailed bridge data
- `output/bridge-note.md` — One-page executive summary with bridge table and drivers

The note summarizes why InterStationary held revenue flat despite significant customer churn, driven by strong upsell performance and new customer acquisition.
