+# @paperclipai/plugin-paperclip-ee-permissions
+
+Closed-source Paperclip EE plugin that hosts the advanced company access,
+grants, and authorization-policy UX.
+
+## Status
+
+Phase 5 implementation surface. The plugin registers a `companySettingsPage`
+slot at `/permissions`, activates a per-company EE mode stub, and renders the
+advanced authorization controls through typed plugin-SDK access and
+authorization clients.
+
+## Capabilities
+
+- `access.members.read` / `access.members.write`
+- `access.invites.read` / `access.invites.write`
+- `authorization.grants.read` / `authorization.grants.write`
+- `authorization.policies.read` / `authorization.policies.write`
+- `authorization.audit.read`
+- `companies.read`, `agents.read`, `issues.read`
+- `plugin.state.read`, `plugin.state.write`
+- `instance.settings.register`, `ui.page.register`
+
+The plugin never imports from `ui/src/api/access.ts` or any other host UI
+internal — all data flows through `ctx.access.*` and `ctx.authorization.*`.
+
+## Deterministic missing-state UX
+
+The page renders one of three states:
+
+| Condition                                  | UI                                                    |
+| ------------------------------------------ | ----------------------------------------------------- |
+| `companyId === null`                       | "No active company" card                              |
+| License inactive for company               | "Advanced permissions mode is not active" with Activate button |
+| License active, host returns capability or worker error | Inline warning card; rest of the page still renders |
+
+## Advanced surfaces
+
+When licensed, the company settings page exposes:
+
+- Agent visibility policy editing (`discoverable` / `private`).
+- Assignment policy editing with broad, scoped-to-agent, and clear grant modes.
+- Protected-agent approval requirement fields.
+- Permission preview and explanation panels that call the same core
+  authorization decision path used by enforcement.
+- Authorization audit filters for actor, resource, action, and decision.
+
+The license check is a per-company plugin-state stub today; later phases
+replace it with a core-owned `advanced_permissions_enabled` flag.
+
+## Scripts
+
+- `pnpm build` — bundle worker, manifest, and UI via esbuild
+- `pnpm test` — run vitest harness tests for the worker
+
+## Layout
+
+```
+src/
+  manifest.ts          # Slot + capability declarations
+  worker.ts            # getData / performAction handlers
+  ui/
+    index.tsx          # Re-exports the slot component
+    app.tsx            # EePermissionsCompanySettingsPage
