ADR 005: Feature Toggle Pattern

Status

Accepted

Context

Platform products need optional features (SSO, alerting, ingress) without duplicating Compositions.

Decision

Use boolean feature toggles in the XRD schema and patch-based conditional resource creation via function-patch-and-transform. Future iterations may migrate to custom Composition Functions.

Consequences

• Single Composition supports multiple configurations.
• Patch-based toggles set replicas: 0 for disabled resources.
• Composition Functions enable true conditional creation in Phase 6.
