#+title: Infrastructure Lock-In and Switching Costs
#+filetags: :passepartout:economics:moats:lock-in:switching:

A hospital that runs Passepartout with HIPAA gate rules ($50K/yr) for five years has accumulated:

- A fact store with a decade of compliance decisions
- A proof forest of verified rules
- An empirical decision history tied to their specific deployment
- Customized gate rules encoding their specific workflows and approvals

Switching to a competitor means discarding all of it. The accumulated value grows as the fact store deepens. Annual revenue per enterprise grows from $250K in year one to $500K-$1M by year five as more domain packages are added.

This is the strongest residual moat. The evaluation harness (regression suite) is a close second — it grows with every deployment and cannot be ingested from public data.
