vertical-slice-gate

What problem does it solve?

This policy enforces bottom-up progression by ensuring vertical-slice completion checks are satisfied before higher-layer features are pursued, reducing risk of downstream churn.

Core Features & Use Cases

• Define slice boundaries and acceptance criteria to limit scope and ensure clear handoffs.
• Run mandatory checks (build, regression tests, smoke tests) and log outcomes to a progress document.
• Enforce a strict exit criteria before moving to the next layer, including documentation updates and evidence of validation.

Quick Start

Declare the slice boundary and acceptance criteria, implement only minimal cross-layer scope for that slice, run the mandatory checks, log progress, and then advance to the next layer.
