Perfect! I've completed the FY2025 revenue bridge analysis for InterStationary. Here's what was generated:

## Summary

**Output files created:**
- `output/bridge.json` — Bridge calculations (all figures verified to reconcile to the cent)
- `output/bridge-note.md` — Commentary note ready for presentation

**Key findings:**

InterStationary's revenue remained essentially flat at $11.2M in FY2025, declining by just ($5K) or (0.04%) year-over-year. This masks significant customer-level movements:

- **Losses dominated**: Four customers churned for ($1.3M), led by Fenwick Legal ($686K) and Birchway Foods ($503K)
- **Upsells offset losses**: 23 customers expanded, generating $1.2M in growth, with Harbor Freight Partners (+$148K), Ember Analytics (+$136K), and Alder Logistics (+$126K) leading
- **New logos contributed**: Six new customers added $463K, including Thistle Gardens ($116K) and Verdant Landscaping ($95K)
- **Timing advances helped**: Three customers with $53K in timing adjustments provided additional support

The revenue bridge maintains the precise reconciliation required for financial reporting, with all figures traced to the source CSV and script output.
