Budget Rollup

Aggregate budgets from teams to departments to organization using UP propagation.
Access Control

Role-based permissions with inheritance through organizational hierarchy.
Configuration Audit

Generate audit reports showing where every value comes from.

Mode	Best For	Examples
INHERIT	Defaults & inheritance	SaaS, Feature Flags, Infrastructure
AGGREGATE	Aggregation & rollups	Budget Rollup, Access Control
MERGE	Layered configurations	Kubernetes, GitOps, Multi-Cloud
NONE	Local-only values	Audit (checking what's set locally)
