+## Scope
+
+This repository owns tenant lifecycle, tenant administration, tenant context resolution, and tenant settings over Core's shared scope storage.
+
+## Documentation Contract
+
+- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
+- Keep feature content here; `govoplan-docs` projects it without importing Tenancy internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.
+
+## Boundaries
+
+- Core owns shared scope storage; Access owns authentication and permission evaluation.
+- Preserve tenant isolation, ownership, and lifecycle recovery guarantees.

 `govoplan-tenancy` owns tenant lifecycle, tenant administration API route
-contributions, and the `tenancy.tenantResolver` capability during the GovOPlaN
+contributions, the `tenancy.tenantResolver` capability, and the tenant registry
-module split.
+and tenant settings WebUI panels during the GovOPlaN module split.
 
 `govoplan-access` no longer hard-depends on this module. Access can run in the
 single-scope compatibility mode used by the core/access baseline; installing
 tenancy adds explicit tenant management and resolver behavior. The shared scope
 storage table is core-owned as `core_scopes`; tenancy provides lifecycle and
 administration behavior over those rows rather than owning the table.
+
+The `@govoplan/tenancy-webui` package contributes `system-tenants` and
+`tenant-settings` through the shared `admin.sections` capability. The Access
+module owns the `/admin` shell but does not import these panels. Historical
+`access.admin.*` surface identifiers remain stable so existing saved Views keep
+working after the ownership move.
+
+The tenant registry and active-tenant settings follow the shared interface
+pattern contract documented in
+[`docs/INTERFACE_PATTERN_MIGRATION.md`](docs/INTERFACE_PATTERN_MIGRATION.md).
+Manifest-provided documentation topics back contextual help for tenant fields,
+governance limits, permission blockers, and lifecycle consequences.
+
+Core's `module_entitlements` tenant-setting key is reserved. Generic tenant
+updates preserve it even when replacing the remaining settings document;
+system and tenant module administrators change it through the Admin module's
+dedicated, revision-checked module policy APIs.

+# Tenancy Interface Pattern Migration
+
+This document records the bounded migration of Tenancy-owned WebUI surfaces to
+the GovOPlaN interface pattern language. Core owns the shared components and the
+Admin host; Tenancy owns the behavior and documentation described here.
+
+## Surface Inventory
+
+| Surface | Archetype | Consequence class | Contract |
+| --- | --- | --- | --- |
+| `tenancy.admin.system-tenants` | Administration directory and list-detail | Create, configure, suspend | Shared admin layout, DataGrid, stable row actions, adaptive create/edit dialog, lifecycle confirmation, contextual help |
+| Tenant details dialog | Read-only evidence/detail | None | Stable labels, effective governance provenance, retained object counts |
+| `tenancy.admin.tenant-settings` | Effective configuration | Configure | Shared admin layout, language selection, dirty-state guard, permission blocker, contextual help |
+
+## Consequence And Availability Rules
+
+- Creating a tenant establishes a new data and administration boundary and
+  provisions a protected initial owner.
+- Tenant slugs are immutable after creation.
+- System policy caps tenant governance overrides. A tenant can narrow an
+  allowance but cannot loosen a system denial.
+- Suspension retains tenant-owned records and audit evidence. The active
+  tenant cannot be suspended until the operator changes context.
+- Unavailable actions remain visible when they belong to the surface and state
+  the missing permission, inapplicable state, responsible actor, and
+  destination where applicable.
+- Dirty dialogs and settings use the shared unsaved-change guard. Consequential
+  suspension continues to use the shared destructive confirmation dialog.
+
+## State And Accessibility Evidence
+
+The panels use Core loading, error, success, empty, disabled-action, blocker,
+dialog, and status components. Row actions reserve a stable three-action area,
+retain translated accessible labels, and do not disappear for row-specific
+permission or lifecycle states. Dialog order follows identity, ownership,
+locale/status, description, and governed capabilities. Shared dialogs own focus
+containment and restoration, and the existing Admin shell provides responsive
+composition.
+
+Stable help references are contributed through the module manifest for the
+tenant registry, tenant settings, lifecycle actions, and individual fields.
+The WebUI structural test and backend documentation-contract test prevent those
+references and state explanations from silently regressing.
