+# Dev Plan: FR-2209 Project Admin Management
+
+## Spec Reference
+
+`.specs/FR-2209-project-admin-management/spec.md` (merged 2026-03-26, 4th review)
+
+## Epic
+
+**FR-2209** — WebUI 프로젝트 관리자 기능 (Project Admin Management)
+
+Related upstream spec PR (open): #6026 — FR-2314 "RBAC admin menu behavior" (FR-1692 epic). This dev plan absorbs FR-2314's UI requirements (3-tier menu, header selector, badge, switch confirm) into FR-2209 implementation.
+
+---
+
+## Backend Reality Check (verified against `lablup/backend.ai` HEAD)
+
+| Capability | Status | Notes |
+|---|---|---|
+| `myRoles` query (with permissions) | ✅ available since 26.3.0 | Local `data/schema.graphql` may need re-pull |
+| `projectRoles(projectId)` | ✅ 26.4.0 | Lists roles in a project scope |
+| `PROJECT_ADMIN_PAGE` element type | ✅ in `RBACElementType` enum | **Primary signal for "is project admin"** — preferred over role-name parsing |
+| `compute_session_nodes(scope_id: "project:<uuid>")` RBAC filtering | ✅ | |
+| `vfolder_nodes(scope_id: "project:<uuid>")` RBAC filtering | ✅ | |
+| `endpoint_list` / Serving RBAC | ❌ **gap** — still legacy `project: UUID` arg, no `endpoint_nodes` Relay node | PR-2b blocked or interim implementation |
+| `unassignUsersFromProjectV2` callable by project admin | ✅ 26.4.0 | Out of initial scope (no member mutations in v1) |
+| Project-member listing by UUID | ⚠️ `adminUsersV2` filters by project **name** only | Use `projectRoles → role.users` connection or name filter |
+
+**`scope_id` format**: `project:<uuid>` (verified in `models/rbac/__init__.py`).
+

+
+## WebUI Current State
+
+- `useCurrentUserRole()` exists (`react/src/hooks/backendai.tsx`) — returns string role
+- Admin pages exist as **superadmin global views**, no project scoping yet:
+  - `AdminComputeSessionListPage.tsx`, `AdminServingPage.tsx`, `AdminVFolderNodeListPage.tsx`
+- `useCurrentUserProjectRoles` / `useEffectiveAdminRole` — **do not exist**
+- `ProjectSelect.tsx` — no admin badge
+- `WebUISider.tsx` `hasAdminCategoryRole` — simple role-string check
+- `WebUIHeader.tsx` — project selector always visible
+

+## Sub-tasks
+
+### PR-0 — Schema sync + role detection hook (BLOCKING)
+
+- **Title**: `feat(FR-2209): add useCurrentUserProjectRoles hook with myRoles RBAC query`
+- **Scope**:
+  - Pull latest schema (`data/schema.graphql`) so `myRoles`/`projectRoles` are present; regenerate Relay artifacts.
+  - Create `react/src/hooks/useCurrentUserProjectRoles.ts`:
+    - `useLazyLoadQuery` against `myRoles`
+    - Returns `{ isSuperAdmin, domainAdminDomains: string[], projectAdminIds: string[], rawAssignments }`
+    - Detection: collect `scopeId` where `permissions[].scopeType === 'PROJECT' && permissions[].entityType === 'PROJECT_ADMIN_PAGE'`
+    - Fallback to role-name parsing (`role_project_<8-hex>_admin`) if `PROJECT_ADMIN_PAGE` permissions not present
+    - Graceful fallback when `myRoles` query is unsupported (older core)
+  - Create `useEffectiveAdminRole()` derived hook returning `'superadmin' | 'domainAdmin' | 'projectAdmin' | 'none'` (priority: super > domain > project)
+  - Unit tests covering super, domain, project, mixed, and no-role cases
+- **Files**: `react/src/hooks/useCurrentUserProjectRoles.ts` (new), `data/schema.graphql`
+- **Dependencies**: none (stack base)
+- **Acceptance**:
+  - Hook returns correct admin role for each test fixture
+  - `myRoles` query failure does not break general pages (returns `none`)
+  - `pnpm run relay && bash scripts/verify.sh` passes
+
+### PR-1a — 3-tier menu visibility + ProjectSelect badge
+
+- **Title**: `feat(FR-2209): add project-admin tier to admin menu and project selector`
+- **Scope**:
+  - `useWebUIMenuItems.tsx` add a `PROJECT_ADMIN_PAGE_KEYS` subset (Session, Serving, Data, Members)
+  - `WebUISider.tsx` `hasAdminCategoryRole = useEffectiveAdminRole() !== 'none'`
+  - `ProjectSelect.tsx` render "Project Admin" badge for projects in `projectAdminIds` (hidden if user is also superadmin/domainAdmin)
+- **Files**: `react/src/hooks/useWebUIMenuItems.tsx`, `react/src/components/MainLayout/WebUISider.tsx`, `react/src/components/ProjectSelect.tsx`
+- **Dependencies**: PR-0
+- **Acceptance** (FR-2314 spec):
+  - Project-admin-only user sees Admin menu category when current project has admin rights
+  - Domain admin / superadmin always see Admin menu
+  - Badge shows on admin projects for project-admin users only
+
+### PR-1b — Header selector + transition confirm
+
+- **Title**: `feat(FR-2209): control header project selector by admin role and confirm switch out of admin scope`
+- **Scope**:
+  - `WebUIHeader.tsx`: in admin mode, show project selector only for project admins; hide for domain/super admin
+  - On project change in admin mode, if target project not in `projectAdminIds`, show confirm dialog ("You don't have admin rights for this project. Switching will exit admin mode.")
+  - Accept → switch project + leave admin mode; cancel → restore selector
+- **Files**: `react/src/components/MainLayout/WebUIHeader.tsx`
+- **Dependencies**: PR-1a
+- **Acceptance** (FR-2314 spec): switch confirm flow + selector visibility per role
+
+### PR-2a — Admin Sessions project scope
+
+- **Title**: `feat(FR-2209): scope admin sessions by project for project admins`
+- **Scope**:
+  - `AdminComputeSessionListPage.tsx`: derive `scope_id` from `useEffectiveAdminRole` × `useCurrentProject`
+    - projectAdmin → `project:<uuid>`
+    - domainAdmin → domain-level filter (TBD per backend; may need TODO marker if no domain-scope arg)
+    - superadmin → no scope (current behavior)
+  - Owner column always visible; Agent column superadmin only (existing `hideAgents` rule)
+  - Do **not** change `SessionActionButtons.tsx` `isOwner` checks — spec confirms App launcher / terminal / SFTP / commit / rename remain owner-only
+- **Files**: `react/src/pages/AdminComputeSessionListPage.tsx`
+- **Dependencies**: PR-0
+- **Acceptance**: spec §스토리 1 acceptance criteria
+
+### PR-2b — Admin Serving project scope (⚠ backend gap)
+
+- **Title**: `feat(FR-2209): scope admin serving by project for project admins`
+- **Scope**:
+  - `AdminServingPage.tsx`: pass project filter
+  - **Path A (preferred)**: wait for backend `endpoint_list(scope_id)` or `endpoint_nodes` Relay node, then use it
+  - **Path B (interim)**: use legacy `endpoint_list(project=<uuid>)` arg with `TODO(needs-backend): FR-2313` marker for domain admin scope and full RBAC validation
+  - "Start Service" button hidden in admin mode (DN-4 confirmed)
+  - Modify/delete remain enabled (current `EndpointList` already has no owner gating for these)
+- **Files**: `react/src/pages/AdminServingPage.tsx`
+- **Dependencies**: PR-0; backend coordination
+- **Acceptance**: spec §스토리 2 acceptance criteria
+- **Risk**: backend gap; file backend follow-up issue
+
+### PR-2c — Admin VFolder + project folder creation
+
+- **Title**: `feat(FR-2209): scope admin vfolders by project and allow project folder creation in admin mode`
+- **Scope**:
+  - `AdminVFolderNodeListPage.tsx`: `scope_id: "project:<uuid>"` + `ownership_type === 'project'` filter
+  - Add `FolderCreateModal` integration: type locked to `project`, project locked to current project (DN-5)
+  - Permission management entry points (invite/remove users, change access level) preserved
+- **Files**: `react/src/pages/AdminVFolderNodeListPage.tsx`, related modal usage
+- **Dependencies**: PR-0
+- **Acceptance**: spec §스토리 3 acceptance criteria
+
+### PR-2d — Project Members read-only page
+
+- **Title**: `feat(FR-2209): add project members list page for project admins`
+- **Scope**:
+  - New page `react/src/pages/ProjectMemberListPage.tsx`
+  - Route `/admin-members` (or under existing menu key); add to admin menu for project/domain/super admins
+  - Query strategy: `projectRoles(projectId) → role.users` collection (preferred), with `adminUsersV2(filter: {project: {name}})` fallback
+  - Columns: name, email, project role (admin/member)
+  - **No CUD UI** (initial scope); spec §스토리 4
+- **Files**: new page, route entry, menu entry, i18n keys
+- **Dependencies**: PR-0
+- **Acceptance**: spec §스토리 4 acceptance criteria
+
+### PR-3 — E2E + i18n + final verification
+
+- **Title**: `test(FR-2209): add E2E coverage and finalize translations for project admin`
+- **Scope**:
+  - Playwright tests using project-admin account (`project-admin-for-default@lablup.com`) on test server `http://10.122.10.215:8090`:
+    - Login → Admin menu visible → each Admin page shows only `default` project data
+    - Project selector badge visible
+    - Switch to non-admin project → confirm dialog appears
+  - i18n keys for all new strings (badge, confirm dialog, page titles)
+  - `bash scripts/verify.sh` clean across stack
+  - Run `/fw:batch-review` against the stack
+- **Dependencies**: all prior PRs
+
+---
+
+## Open Questions & Risks
+
+1. **Schema sync procedure**: how is `data/schema.graphql` refreshed (make target / manual fetch)? Confirm before PR-0.
+2. **Serving backend gap**: file follow-up backend issue (or coordinate with backend team) — spec claims confirmed but schema disagrees.
+3. **`PROJECT_ADMIN_PAGE` permission grant**: verify at runtime that the `role_project_<id>_admin` actually carries this permission; if not, role-name fallback is the actual signal.
+4. **Domain admin scope arg**: which GraphQL arg (or RBAC scope string) does the WebUI pass for `domain:<name>` filtering on session/vfolder queries?
+5. **Project member query**: validate that `projectRoles → role.users` connection is reliable in production data.
+6. **PR #6026 disposition**: with FR-2314 absorbed here, decide whether to close #6026 or merge it as historical context (with PO).

+
+## Verification
+
+Test target (per user instruction):
+
+```
+E2E_WEBSERVER_ENDPOINT=http://10.122.10.215:8090
+E2E_USER_EMAIL=project-admin-for-default@lablup.com
+E2E_USER_PASSWORD="CWR0y4s5E9p#"
+```
+
+Account is **project admin of the `default` project**. Verifies PR-0 through PR-3 acceptance criteria end-to-end.
