 # ADR-0057: ERP-Grade Authorization Core — Business-Unit Partitioning, Scope-Depth Grants, and Hierarchy Rollup

 - Rollup is **additive only** (widens, never restricts) and respects tenant isolation. It powers both
   D1's `unit*` scopes and sharing-rule recipients (D6). Because it is pure pre-resolution, the choice
   of *which* tree drives visibility is an authoring/modelling decision, not a runtime-mechanism one.

 - The leaf joins the per-driver conformance case-sets, so a driver that compiles it is measured and one that refuses
   is recorded as refusing.
