APR-Lite v8.2.0 — Agentic Coordination Layer: Phase 8 Complete

APR-Lite (AI Prior Review — Lite) is a substrate-layer governance engine protecting human decision-making from AI-influenced outputs in regulated industries. This record documents the completion of Phase 8 (v8.2.0), the agentic coordination layer. Phase 8.2 completes the 8.x line with the following capabilities confirmed operational and tested: Agentic coordination layer (Phase 8) — live Session governance with substrate evaluation Multi-tenant isolation with independent governance contexts Global governance layer with cross-tenant coalition drift aggregation Officer registry with role-based access control Freeze state management (global and tenant-scoped) Audit log with immutable event records 38 tests passing across all governance surfaces Architecture properties confirmed in Phase 8.2: Tenant isolation: hard boundary — same input, different governance contexts, independent outcomes. No data, sessions, or policies cross the boundary. Global layer: highest-precedence governance state. Can tighten tenant configurations, disable topology types, and freeze the entire platform. It can never loosen a tenant's existing constraints. Substrate evaluation: every agent output evaluated before delivery. All actor constraints satisfied before clearance. This release establishes the federation boundary that Phase 9 (cross-tenant reads under explicit policy) will extend.
