Done! I've built the FY2025 revenue bridge for InterStationary and created the commentary note. Here's what happened:

**Summary:**
- FY2025 revenue was essentially flat at $11,238K vs. $11,243K in FY2024, down just ($5K) or (0.04%)
- The near-flat result masks significant churn: $1,288K in lost customers and $443K in declines were nearly offset by $1,211K in upsells and $463K from six new customers
- Key losses include Fenwick Legal ($686K) and Birchway Foods ($503K), while Harbor Freight Partners, Ember Analytics, and Alder Logistics drove upsell gains

**Files created:**
- `output/bridge.json` — detailed script output with all calculations
- `output/bridge-note.md` — one-page commentary with headline, bridge table, drivers, and data notes

The note follows the revenue-bridge output contract exactly: headline with totals and change, bridge table with all movements, driver bullets naming key customers, and data provenance with the file hash.
