+## Implementation Status
+
+Implemented in the initial Views slice:
+
+- Core contract version `1`, stable module/navigation/route identifiers, custom
+  section/action descriptors, manifest validation, and platform API metadata
+- shell navigation, route-boundary, settings, administration, dashboard-widget,
+  embedded-capability, and organization-action filtering
+- `govoplan-views` definitions, immutable revisions, system/tenant/group/user
+  assignments, user selection, provenance, and stale-surface recovery
+- a system and tenant administration editor with unsaved-change protection,
+  publish/archive controls, assignment management, and server-enforced lockout
+  prevention
+- surface declarations for every currently installed module that contributes a
+  WebUI, including finer-grained shared administration and settings surfaces
+
+Still intentionally separate:
+
+- Policy-owned inherited ceilings and policy decision provenance
+- workflow-instance and workflow-step activation of pinned View revisions
+- read-only and layout-replacement projections beyond the version `1`
+  visible/hidden contract
+
