One concrete deliverable per stage. You sign off on each before the next one starts.
- Diagnose. A written scope and a fixed price. What we will build, what it will change and what it costs, on paper before you commit.

- Embed. Handover, documentation and training. Your team runs it, and you own the code, the prompts and the data.
