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.
