Feature Verification

Systematic 4-phase process for verifying new features work correctly across all layers: database, code deployment, runtime execution, and end-to-end functionality.

When to Use

• After implementing new features
• When features "should work" but don't behave as expected
• When verifying complex integrations
• After deployments to production
• When debugging deployment-related issues

Core Methodology

Follow these 4 phases in order. Each phase builds on the previous one.

Phase 1: Root Cause Investigation

Gather evidence from all layers before forming hypotheses.
