## Goal Achievement

### Observable Truths

Plan 01 truths:

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Platform admin caller gets 200 on any tenant endpoint; non-admin gets 403 | VERIFIED | `rbac.py` raises `HTTP_403_FORBIDDEN` for non-`platform_admin`; 11 unit tests pass |
| 2 | Customer admin gets 200 on their own tenant endpoints; gets 403 on other tenants | VERIFIED | `require_tenant_admin` checks `UserTenantRole` membership; `test_tenant_admin_own_tenant` / `test_tenant_admin_no_membership` pass |
| 3 | Customer operator gets 403 on mutating endpoints; gets 200 on read-only endpoints | VERIFIED | `require_tenant_admin` always rejects operator; `require_tenant_member` allows operator on GET paths |
| 4 | Invite token with valid HMAC and unexpired timestamp validates successfully | VERIFIED | `test_token_roundtrip` passes; `hmac.compare_digest` + 48h TTL enforced in `invite_token.py` |
| 5 | Invite token with tampered signature or expired timestamp raises ValueError | VERIFIED | `test_token_tamper_rejected` and `test_token_expired_rejected` pass |
| 6 | Auth verify response returns role + tenant_ids instead of is_admin | VERIFIED | `AuthVerifyResponse` has `role`, `tenant_ids`, `active_tenant_id`; `is_admin` absent from `PortalUser` model |

Plan 02 truths:

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 7 | JWT token contains role, tenant_ids, and active_tenant_id after login | VERIFIED | `auth.ts` jwt callback sets `token.role`, `token.tenant_ids`, `token.active_tenant_id` (lines 72-74) |
| 8 | Customer operator navigating to /billing is silently redirected to /agents | VERIFIED | `proxy.ts` line 57: `if (role === "customer_operator")` redirects restricted paths to `/agents` |
| 9 | Customer operator does not see Billing, API Keys, or User Management in sidebar | VERIFIED | `nav.tsx` filters `navItems` by `allowedRoles` array via `useSession()` |
| 10 | Customer admin sees tenant dashboard after login | VERIFIED | `proxy.ts` landing page logic: `customer_admin` routes to `/dashboard` |
| 11 | Platform admin sees platform overview with tenant picker after login | VERIFIED | `proxy.ts` `case "platform_admin"` routes to `/dashboard`; `TenantSwitcher` rendered in layout |
| 12 | Multi-tenant user can switch active tenant without logging out | VERIFIED | `tenant-switcher.tsx` calls `update({ active_tenant_id: newTenantId })` (line 71); `auth.ts` jwt callback handles `trigger === "update"` |
| 13 | Impersonation shows a visible banner with exit button | VERIFIED | `impersonation-banner.tsx` 49 lines, amber banner with exit button; integrated in `layout.tsx` |
| 14 | Invite acceptance page accepts token, lets user set password, creates account | VERIFIED | `app/invite/[token]/page.tsx` (172 lines) outside `(dashboard)` group; POSTs to `/api/portal/invitations/accept` |
| 15 | User management page lists users for tenant with invite button | VERIFIED | `app/(dashboard)/users/page.tsx` (411 lines) with invite dialog and resend capability |
| 16 | Platform admin global user page shows all users across all tenants | VERIFIED | `app/(dashboard)/admin/users/page.tsx` (462 lines) with tenant/role filters |

Plan 03 truths:

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 17 | Every mutating portal API endpoint returns 403 for customer_operator | VERIFIED | 16 `Depends(require_tenant_admin)` / `Depends(require_platform_admin)` guards across `portal.py`, `billing.py`, `channels.py`, `llm_keys.py` |
| 18 | Customer operator gets 200 on POST agent test-message endpoint | VERIFIED | `POST /tenants/{tid}/agents/{aid}/test` uses `Depends(require_tenant_member)` (line 622 `portal.py`) |

**Score:** 18/18 truths verified

## Requirements Coverage

| Requirement | Description | Plans | Status | Evidence |
|-------------|-------------|-------|--------|---------|
| RBAC-01 | Platform admin role with full access to all tenants, agents, users, and platform settings | 01, 02, 03 | SATISFIED | `require_platform_admin` guards; platform_admin bypasses all tenant checks; 16 guarded endpoints |
| RBAC-02 | Customer admin role scoped to a single tenant with full control over agents, channels, billing, API keys, and user management | 01, 03 | SATISFIED | `require_tenant_admin` on all mutating tenant endpoints; cross-tenant 403 enforced |
| RBAC-03 | Customer operator role scoped to a single tenant with read-only access to agents, conversations, and usage dashboards | 01, 03 | SATISFIED | `require_tenant_member` on GET endpoints; `require_tenant_admin` blocks operator on mutations; operator CAN send test messages |
| RBAC-04 | Customer admin can invite users by email — invitee receives activation link to set password | 01, 02, 03 | SATISFIED | Full invitation system: HMAC tokens, SMTP email, `invitations_router`, invite acceptance page at `/invite/[token]` |
| RBAC-05 | Portal navigation, pages, and UI elements adapt based on user role | 02 | SATISFIED | Role-filtered nav, proxy redirects, impersonation banner, tenant switcher — all present and wired |
| RBAC-06 | API endpoints enforce role-based authorization — unauthorized actions return 403 | 01, 03 | SATISFIED | FastAPI `Depends()` guards on all 17+ endpoints; integration tests cover full role matrix |

All 6 requirements satisfied. No orphaned requirements.

## Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `packages/shared/shared/api/portal.py` | ~630 | Agent test-message returns stub echo response | Info | Documented decision: full orchestrator wiring deferred; endpoint has correct RBAC, stub response only |

No blocker or warning-level anti-patterns found. The test-message stub is a documented, intentional deferral — RBAC enforcement (the goal of this phase) is correct.

## Human Verification Required

The following items cannot be verified programmatically. All automated checks passed; these items require a running environment.

### 1. End-to-end Invitation Flow in Browser

**Test:** Start dev environment, create invitation as customer_admin, open invite URL in incognito, set password, log in as new user
**Expected:** Account created with correct role and tenant membership; JWT claims match; login succeeds
**Why human:** Full HTTP + DB + email path requires live services

### 2. Operator Path Redirect in Browser

**Test:** Log in as customer_operator, navigate to `/billing` directly
**Expected:** Silently redirected to `/agents` with no error page shown
**Why human:** Proxy behavior requires running Next.js server

### 3. Tenant Switcher Context Switch

**Test:** Log in as user with multiple tenant memberships, use tenant switcher dropdown
**Expected:** Active tenant changes instantly without page reload; TanStack Query refetches data for new tenant
**Why human:** Requires live JWT update flow and visible UI state change

### 4. Impersonation Banner Display

**Test:** Log in as platform_admin, impersonate a tenant via `/admin/impersonate`
**Expected:** Amber banner appears at top of viewport showing tenant name with visible "Exit" button; banner disappears after exit
**Why human:** Visual UI element, requires live session with `impersonating_tenant_id` JWT claim

### 5. Integration Tests Against Live DB

**Test:** `uv run pytest tests/integration/test_portal_rbac.py tests/integration/test_invite_flow.py -x -v`
**Expected:** All 56 integration tests pass (currently skipped in CI due to no DB)
**Why human:** Requires PostgreSQL with migration 006 applied

## Summary

Phase 4 goal is achieved. All three tiers of role-based access control exist and are wired:

- **DB layer:** Migration 006 adds `role` column to `portal_users` (TEXT+CHECK), `user_tenant_roles` table, and `portal_invitations` table. `is_admin` is gone.
- **Backend guards:** `require_platform_admin`, `require_tenant_admin`, `require_tenant_member` implemented with real 403 enforcement and platform_admin bypass logic. Guards wired to all 17+ API endpoints across 5 routers.
- **Invitation system:** HMAC-SHA256 tokens with 48h TTL, token hash stored (never raw token), SMTP email utility, full CRUD API (create/accept/resend/list), Celery task for async email dispatch.
- **Portal JWT:** Auth.js carries `role`, `tenant_ids`, `active_tenant_id` replacing `is_admin`. Tenant switcher updates JWT mid-session via `trigger: "update"`.
- **Portal routing:** Proxy silently redirects `customer_operator` from restricted paths. `/invite/[token]` is public (outside dashboard group).
- **Portal UI:** Nav hides items by role. Impersonation banner is present. User management pages exist for both tenant and platform scope.
- **Tests:** 27 unit tests pass. 56 integration tests written (require live DB to run — documented in summaries).

The one notable deferred item (test-message endpoint returns echo stub pending orchestrator integration) is a documented decision and does not block the RBAC goal.
