Enterprise workflow blueprint

1) Intake and scoping

Turn tickets into explicit acceptance criteria before agent execution.

2) Build and verify

Agent writes code, runs tests, and generates evidence for every change.

3) Human gate and release

Engineer approves risk checks, security gates, and deployment decisions.
