+# Phase 3b·3 — User Management (Gebruikers) — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Let an admin list users (role + status), create users, change roles, reset passwords, and deactivate/reactivate accounts — with server-side guards that make admin lockout impossible.
+
+**Architecture:** A new admin-gated `routes/admin-users.ts` router holds the user endpoints. `role` and `banned` are plain `user` columns, so set-role / deactivate / reactivate are direct Drizzle updates (version-proof, in-process testable); only create and reset-password go through `auth.api.*` (password hashing). A tables-style Gebruikers screen drives it via React Query.
+
+**Tech Stack:** Hono, better-auth (admin + bearer plugins), Drizzle (libsql/SQLite), zod (`@solelog/shared`), React + React Query + Vite (admin), Vitest + Testing Library.
+
+## Global Constraints
+
+- **No hard delete** — deactivation only (`banned`), so `work_sessions` history is never cascade-deleted.
+- **Lockout guards (server-side, 400 + Dutch message):** no self-deactivate (`"Je kunt jezelf niet deactiveren."`); no self-demote (`"Je kunt jezelf niet degraderen."`); last-active-admin invariant (`"Er moet minstens één actieve beheerder blijven."`).
+- **Password floor:** minimum 8 characters (zod `.min(8)`) on create + reset.
+- **Admin-gated:** every `/api/admin/users*` route is behind `adminGuard` → 401 (no session) / 403 (non-admin).
+- **No DB migration:** `role`, `banned`, `banReason`, `banExpires` already exist on `user`.
+- **Status mapping:** `status = banned ? 'inactive' : 'active'`; `role` defaults to `'worker'` when null.
+- **better-auth call shapes** (`auth.api.createUser({ body: { email, password, name, role } })`, `auth.api.setUserPassword({ body: { userId, newPassword }, headers } )`) must be verified against the installed types during implementation; the custom `'worker'` role needs the same local cast as `seed.ts`/`test/helpers.ts`.
+- **Code style:** oxfmt — 2-space, single quotes, semicolons, width 100, trailing-comma `all`. `npx oxfmt <files>` before each commit.
+
+---
+
+### Task 1: Foundation — `adminGuard` middleware + shared contracts
+
+Extract the admin gate so two routers can share it, and add the user contracts. No new behavior — verified by the existing admin suite + typecheck.
+
+**Files:**
+- Modify: `apps/api/src/lib/require-user.ts` (add `adminGuard`)
+- Modify: `apps/api/src/routes/admin.ts:16-21` (use `adminGuard`; drop now-unused imports)
+- Modify: `packages/shared/src/index.ts` (add contracts)
+
+**Interfaces:**
+- Produces: `adminGuard: MiddlewareHandler` (consumed by Tasks 2-5 + `admin.ts`); shared `UserStatus`, `AdminUser` (now with `status`), `CreateUserInput`, `SetRoleInput`, `SetPasswordInput` (consumed by Tasks 2-6).
+
+- [ ] **Step 1: Add `adminGuard` to `require-user.ts`**
+
+Append to `apps/api/src/lib/require-user.ts` (add `MiddlewareHandler` to the type import):
+
+```ts
+import type { Context, MiddlewareHandler } from 'hono';
+```
+
+```ts
+// Reusable gate for the whole /api/admin/* surface: 401 if unauthenticated, 403 if not an admin.
+export const adminGuard: MiddlewareHandler = async (c, next) => {
+  const u = await getSessionUser(c);
+  if (!u) return c.json({ error: 'Unauthorized' }, 401);
+  if (!isAdmin(u)) return c.json({ error: 'Forbidden' }, 403);
+  await next();
+};
+```
+
+- [ ] **Step 2: Use it in `admin.ts`**
+
+In `apps/api/src/routes/admin.ts`, replace the inline guard block:
+
+```ts
+// Gate the whole /api/admin/* surface to admins.
+adminRoutes.use('/api/admin/*', async (c, next) => {
+  const sessionUser = await getSessionUser(c);
+  if (!sessionUser) return c.json({ error: 'Unauthorized' }, 401);
+  if (!isAdmin(sessionUser)) return c.json({ error: 'Forbidden' }, 403);
+  await next();
+});
+```
+
+with:
+
+```ts
+// Gate the whole /api/admin/* surface to admins.
+adminRoutes.use('/api/admin/*', adminGuard);
+```
+
+Update the import in `admin.ts` from `import { getSessionUser, isAdmin } from '../lib/require-user';` to `import { adminGuard } from '../lib/require-user';` (neither `getSessionUser` nor `isAdmin` is used elsewhere in `admin.ts`).
+
+- [ ] **Step 3: Add the shared contracts**
+
+Append to `packages/shared/src/index.ts`:
+
+```ts
+export const UserStatus = z.enum(['active', 'inactive']);
+export type UserStatus = z.infer<typeof UserStatus>;
+
+export const CreateUserInput = z.object({
+  email: z.string().email(),
+  name: z.string().trim().min(1),
+  password: z.string().min(8),
+  role: Role,
+});
+export type CreateUserInput = z.infer<typeof CreateUserInput>;
+
+export const SetRoleInput = z.object({ role: Role });
+export type SetRoleInput = z.infer<typeof SetRoleInput>;
+
+export const SetPasswordInput = z.object({ password: z.string().min(8) });
+export type SetPasswordInput = z.infer<typeof SetPasswordInput>;
+```
+
+Then extend the existing `AdminUser` schema (it is currently `id/email/name/role/created_at` and is unused in app code) by adding a `status` field. Change:
+
+```ts
+export const AdminUser = z.object({
+  id: z.string(),
+  email: z.string().email(),
+  name: z.string(),
+  role: Role,
+  created_at: z.string(),
+});
+```
+
+to:
+
+```ts
+export const AdminUser = z.object({
+  id: z.string(),
+  email: z.string().email(),
+  name: z.string(),
+  role: Role,
+  status: UserStatus,
+  created_at: z.string(),
+});
+```
+
+- [ ] **Step 4: Verify nothing broke**
+
+Run: `yarn workspace @solelog/api test admin && yarn workspace @solelog/api typecheck`
+Expected: PASS — the existing `admin.test.ts` (gating + sessions) is green through the refactored guard; typecheck clean.
+
+- [ ] **Step 5: Format + commit**
+
+```bash
+npx oxfmt apps/api/src/lib/require-user.ts apps/api/src/routes/admin.ts packages/shared/src/index.ts
+git add apps/api/src/lib/require-user.ts apps/api/src/routes/admin.ts packages/shared/src/index.ts
+git commit -m "refactor(api): extract adminGuard + add user-management contracts"
+```
+
+---
+
+### Task 2: `admin-users.ts` router — list (moved + enriched) + create
+
+Create the new router with the enriched roster and user creation. Move `GET /api/admin/users` out of `admin.ts` in the same task so the path is never defined twice.
+
+**Files:**
+- Create: `apps/api/src/routes/admin-users.ts`
+- Modify: `apps/api/src/routes/admin.ts` (remove the old `GET /api/admin/users` block)
+- Modify: `apps/api/src/app.ts` (mount the new router)
+- Test: `apps/api/test/admin-users.test.ts` (new)
+
+**Interfaces:**
+- Consumes: `adminGuard` (Task 1); `CreateUserInput`, `AdminUser` (Task 1).
+- Produces: `adminUsersRoutes` (Hono) and the module-local `toListItem(row)` mapper + `GET`/`POST /api/admin/users` (consumed by Tasks 3-6).
+
+- [ ] **Step 1: Write the failing test**
+
+Create `apps/api/test/admin-users.test.ts`:
+
+```ts
+import { describe, it, expect } from 'vitest';
+import type { Hono } from 'hono';

+    });
+    expect(res.status).toBe(403);
+  });
+});
+```
+
+- [ ] **Step 2: Run it to verify it fails**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: FAIL — `/api/admin/users` is now unmounted (we remove it from `admin.ts` next) / new POST returns 404.
+
+- [ ] **Step 3: Create the router**
+
+Create `apps/api/src/routes/admin-users.ts`:
+
+```ts
+import { Hono } from 'hono';
+import { asc, eq } from 'drizzle-orm';
+import { CreateUserInput, type AdminUser, type Role } from '@solelog/shared';
+import { db } from '../db/client';
+import { session, user } from '../db/schema';
+import { auth } from '../auth';
+import { adminGuard } from '../lib/require-user';
+
+export const adminUsersRoutes = new Hono();
+
+adminUsersRoutes.use('/api/admin/users', adminGuard);
+adminUsersRoutes.use('/api/admin/users/*', adminGuard);
+
+type UserRow = typeof user.$inferSelect;
+
+// Map a user row to the public list shape.
+export function toListItem(row: UserRow): AdminUser {
+  return {
+    id: row.id,
+    email: row.email,
+    name: row.name,
+    role: (row.role ?? 'worker') as Role,
+    status: row.banned ? 'inactive' : 'active',
+    created_at: new Date(row.createdAt).toISOString(),
+  };
+}
+
+// Enriched roster (replaces the old id/name/email version from admin.ts).
+adminUsersRoutes.get('/api/admin/users', async (c) => {
+  const rows = await db.select().from(user).orderBy(asc(user.name));
+  return c.json(rows.map(toListItem));
+});
+
+// Create a user. role/password validated by zod; password hashing via better-auth.
+adminUsersRoutes.post('/api/admin/users', async (c) => {
+  const parsed = CreateUserInput.safeParse(await c.req.json().catch(() => null));
+  if (!parsed.success) return c.json({ error: 'Invalid input' }, 400);
+  const d = parsed.data;
+
+  // better-auth types role as its built-in set; our 'worker' role is valid at runtime (same cast as seed.ts).
+  const createUser = auth.api.createUser as (args: {
+    body: { email: string; password: string; name: string; role: 'worker' | 'admin' };
+  }) => Promise<unknown>;
+
+  try {
+    await createUser({ body: { email: d.email, password: d.password, name: d.name, role: d.role } });
+  } catch {
+    // Inputs are pre-validated, so the realistic failure is a duplicate email.
+    return c.json({ error: 'E-mailadres bestaat al.' }, 409);
+  }
+
+  const [row] = await db.select().from(user).where(eq(user.email, d.email));
+  return c.json(toListItem(row));
+});
+```
+
+- [ ] **Step 4: Remove the old roster from `admin.ts`**
+
+In `apps/api/src/routes/admin.ts`, delete the entire `GET /api/admin/users` handler (the block with the comment "Roster for the create-form worker picker…" through its closing `});`). Leave `baseSelect`, the session routes, report, and export untouched.
+
+- [ ] **Step 5: Mount the router**
+
+In `apps/api/src/app.ts`, import and mount it after `adminRoutes`:
+
+```ts
+import { adminUsersRoutes } from './routes/admin-users';
+```
+
+```ts
+  app.route('/', adminRoutes);
+  app.route('/', adminUsersRoutes);
+```
+
+- [ ] **Step 6: Run the test to verify it passes**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: PASS — all list + create cases green.
+
+- [ ] **Step 7: Full API suite (regression: pickers still work), typecheck, format, commit**
+
+```bash
+yarn workspace @solelog/api test
+yarn workspace @solelog/api typecheck
+npx oxfmt apps/api/src/routes/admin-users.ts apps/api/src/routes/admin.ts apps/api/src/app.ts apps/api/test/admin-users.test.ts

+git commit -m "feat(api): admin-users router with enriched roster + user creation"
+```
+

+
+### Task 3: Set role + self-demote / last-admin guards
+
+**Files:**
+- Modify: `apps/api/src/routes/admin-users.ts` (add the role route + guard helper)
+- Test: `apps/api/test/admin-users.test.ts` (add a `role` describe block)
+
+**Interfaces:**
+- Consumes: `toListItem` (Task 2); `SetRoleInput` (Task 1); `getSessionUser` (`../lib/require-user`).
+- Produces: `activeAdminsExcluding(id)` helper (consumed by Task 4).
+
+- [ ] **Step 1: Add the failing tests**
+
+Append to `apps/api/test/admin-users.test.ts`. First add this import at the top of the file (alongside the existing imports):
+
+```ts
+import { db } from '../src/db/client';
+import { user } from '../src/db/schema';
+import { eq } from 'drizzle-orm';
+```
+
+Then add:
+
+```ts
+async function userIdByEmail(email: string): Promise<string> {
+  const [row] = await db.select().from(user).where(eq(user.email, email));
+  return row.id;
+}
+
+describe('POST /api/admin/users/:id/role', () => {

+    const id = await userIdByEmail('role-target@example.com');
+
+    const up = await app.request(`/api/admin/users/${id}/role`, {

+
+    const down = await app.request(`/api/admin/users/${id}/role`, {

+
+  it('refuses demoting the last active admin', async () => {
+    const app = createApp();
+    const adminTok = await authToken(app, 'role-last-admin@example.com', 'admin');
+    // Promote a worker, then that worker is the only *other* admin; demote them while the caller
+    // is also admin — but to hit the last-admin path, demote the caller's only peer after demoting caller is blocked.
+    // Simplest: single admin scenario — create a second admin, demote them (ok), then try to demote remaining peer.
+    await authToken(app, 'role-peer@example.com', 'admin');
+    const peerId = await userIdByEmail('role-peer@example.com');
+    // Demote the peer: now caller is the only admin. Allowed (caller remains).
+    await app.request(`/api/admin/users/${peerId}/role`, {
+      method: 'POST',
+      headers: bearer(adminTok),
+      body: JSON.stringify({ role: 'worker' }),
+    });
+    // Re-promote peer, then demote caller-equivalent is blocked by self-guard; instead verify the
+    // invariant directly: ban the caller is self-blocked, so assert the helper via a constructed case.
+    // Here we assert: with only the caller as admin, demoting *any other* admin is impossible because none exist,
+    // so we validate the guard by promoting peer again and confirming a non-self demote still leaves >=1 admin (caller).
+    await app.request(`/api/admin/users/${peerId}/role`, {
+      method: 'POST',
+      headers: bearer(adminTok),
+      body: JSON.stringify({ role: 'admin' }),
+    });
+    const res = await app.request(`/api/admin/users/${peerId}/role`, {
+      method: 'POST',
+      headers: bearer(adminTok),
+      body: JSON.stringify({ role: 'worker' }),
+    });
+    // caller is still admin, so demoting the peer is allowed (>=1 admin remains).
+    expect(res.status).toBe(200);
+  });
+});
+```
+
+Note: because the acting admin always remains an admin, the *non-self* last-admin path returns 200; the genuine last-admin protection is exercised through the self-demote guard above and the deactivate tests in Task 4. The helper is still implemented and used so the invariant holds if the self-guard is ever bypassed.
+
+- [ ] **Step 2: Run it to verify it fails**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: FAIL — the role route returns 404.
+
+- [ ] **Step 3: Implement the role route + helper**
+
+In `apps/api/src/routes/admin-users.ts`, add `getSessionUser` to the require-user import:
+
+```ts
+import { adminGuard, getSessionUser } from '../lib/require-user';
+```
+
+Add `SetRoleInput` to the shared import:
+
+```ts
+import { CreateUserInput, SetRoleInput, type AdminUser, type Role } from '@solelog/shared';
+```
+
+Add the helper + route (after the create route):
+
+```ts
+// Count admins that are active (not banned), excluding one user id.
+export async function activeAdminsExcluding(excludeId: string): Promise<number> {
+  const admins = await db.select({ id: user.id, banned: user.banned }).from(user).where(eq(user.role, 'admin'));
+  return admins.filter((a) => !a.banned && a.id !== excludeId).length;
+}
+
+adminUsersRoutes.post('/api/admin/users/:id/role', async (c) => {
+  const id = c.req.param('id');
+  const parsed = SetRoleInput.safeParse(await c.req.json().catch(() => null));
+  if (!parsed.success) return c.json({ error: 'Invalid input' }, 400);
+  const newRole = parsed.data.role;
+
+  const caller = await getSessionUser(c);
+  const [target] = await db.select().from(user).where(eq(user.id, id));
+  if (!target) return c.json({ error: 'Gebruiker niet gevonden' }, 404);
+
+  if (id === caller?.id && newRole !== 'admin') {
+    return c.json({ error: 'Je kunt jezelf niet degraderen.' }, 400);
+  }
+  if (target.role === 'admin' && newRole !== 'admin') {
+    if ((await activeAdminsExcluding(id)) === 0) {
+      return c.json({ error: 'Er moet minstens één actieve beheerder blijven.' }, 400);
+    }
+  }
+
+  await db.update(user).set({ role: newRole }).where(eq(user.id, id));
+  const [updated] = await db.select().from(user).where(eq(user.id, id));
+  return c.json(toListItem(updated));
+});
+```
+
+Note `eq`/`user`/`db` are already imported (eq from Task-2 imports; `db`/`user` from Task 2). The Task-3 test file adds its own `eq`/`db`/`user` imports for the test helper.
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: PASS.

+- [ ] **Step 5: Typecheck, format, commit**
+
+```bash

+- [ ] **Step 2: Run it to verify it fails**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: FAIL — the password route returns 404.
+
+- [ ] **Step 3: Implement the password route**
+
+In `apps/api/src/routes/admin-users.ts`, add `SetPasswordInput` to the shared import:
+
+```ts
+import { CreateUserInput, SetPasswordInput, SetRoleInput, type AdminUser, type Role } from '@solelog/shared';
+```
+
+Add the route. **Verify** `auth.api.setUserPassword`'s exact shape against the installed types before finalizing; the expected shape is `{ body: { userId, newPassword }, headers }`:
+
+```ts
+adminUsersRoutes.post('/api/admin/users/:id/password', async (c) => {
+  const id = c.req.param('id');
+  const parsed = SetPasswordInput.safeParse(await c.req.json().catch(() => null));

+
+  const [target] = await db.select().from(user).where(eq(user.id, id));
+  if (!target) return c.json({ error: 'Gebruiker niet gevonden' }, 404);
+
+  try {
+    await auth.api.setUserPassword({
+      body: { userId: id, newPassword: parsed.data.password },
+      headers: c.req.raw.headers,
+    });
+  } catch {
+    return c.json({ error: 'Wachtwoord wijzigen mislukt.' }, 400);
+  }
+  return c.json({ success: true });
+});
+```
+
+- [ ] **Step 4: Run the test to verify it passes**
+
+Run: `yarn workspace @solelog/api test admin-users`
+Expected: PASS. If `setUserPassword` is unavailable/different in the installed better-auth, adjust to the correct admin method (verify via `node_modules/better-auth/dist/plugins/admin/admin.d.mts`) — the test asserts the behavior, not the call shape.
+

+  );
+}
+```
+
+- [ ] **Step 6: Wire nav + route**
+
+In `apps/admin/src/components/Sidebar.tsx`, add Gebruikers to `navItems` and remove the now-empty soon block. Replace:
+
+```tsx
+const navItems = [
+  { to: '/', label: 'Live' },
+  { to: '/handelingen', label: 'Handelingen' },
+  { to: '/sessies', label: 'Sessies' },
+  { to: '/rapporten', label: 'Rapporten' },
+] as const;
+
+// Sections planned for the final Phase 3b cycle — shown muted/disabled.
+const soonItems = ['Gebruikers'] as const;
+```
+
+with:
+
+```tsx
+const navItems = [
+  { to: '/', label: 'Live' },
+  { to: '/handelingen', label: 'Handelingen' },
+  { to: '/sessies', label: 'Sessies' },
+  { to: '/rapporten', label: 'Rapporten' },
+  { to: '/gebruikers', label: 'Gebruikers' },
+] as const;
+```
+
+Then delete the JSX block that renders `soonItems` (the `<div className="nav-soon">…</div>` containing the `soonItems.map(...)`), since `soonItems` no longer exists.
+
+In `apps/admin/src/App.tsx`, import and add the route:
+
+```tsx
+import Users from './screens/Users';
+```
+
+```tsx
+            <Route path="/rapporten" element={<Reports />} />
+            <Route path="/gebruikers" element={<Users />} />
+```
+
+- [ ] **Step 7: Add styles**
+
+Append to `apps/admin/src/styles.css`:
+
+```css
+.users-table {
+  width: 100%;
+  border-collapse: collapse;
+  margin-top: 1rem;
+}
+.users-table th,
+.users-table td {
+  text-align: left;
+  padding: 0.5rem 0.6rem;
+  border-bottom: 1px solid var(--border, #e4e4e7);
+  vertical-align: middle;
+}
+.users-actions {
+  display: flex;
+  flex-wrap: wrap;
+  gap: 0.4rem;
+}
+.users-reset {
+  display: inline-flex;
+  gap: 0.3rem;
+  align-items: center;
+}
+.pill {
+  display: inline-block;
+  padding: 0.1rem 0.5rem;
+  border-radius: 999px;
+  font-size: 0.75rem;
+  font-weight: 600;
+}
+.pill-admin {
+  background: #ede9fe;
+  color: #6d28d9;
+}
+.pill-worker {
+  background: #e0f2fe;
+  color: #0369a1;
+}
+.pill-active {
+  background: #dcfce7;
+  color: #15803d;
+}
+.pill-inactive {
+  background: #fee2e2;
+  color: #b91c1c;
+}
+.user-self-badge {
+  font-size: 0.7rem;
+  color: var(--muted, #71717a);
+  font-style: italic;
+}
+.user-form {
+  display: flex;
+  flex-wrap: wrap;
+  gap: 0.75rem;
+  align-items: flex-end;
+  padding: 1rem;
+  background: var(--surface, #f4f4f5);
+  border-radius: 0.5rem;
+  margin-bottom: 1rem;
+}
+.user-form label {
+  display: flex;
+  flex-direction: column;
+  gap: 0.25rem;
+  font-size: 0.8rem;
+}
+.user-form-actions {
+  display: flex;
+  gap: 0.5rem;
+}
+```
+
+- [ ] **Step 8: Run the screen test**
+
+Run: `yarn workspace @solelog/admin test Users`
+Expected: PASS — all four cases green.
+
+- [ ] **Step 9: Full admin suite, typecheck, build, format, commit**
+
+```bash
+yarn workspace @solelog/admin test
+yarn workspace @solelog/admin typecheck
+yarn workspace @solelog/admin build
+npx oxfmt apps/admin/src/api/users.ts apps/admin/src/components/UserForm.tsx apps/admin/src/screens/Users.tsx apps/admin/src/screens/Users.test.tsx apps/admin/src/components/Sidebar.tsx apps/admin/src/App.tsx
+git add apps/admin/src/api/users.ts apps/admin/src/components/UserForm.tsx apps/admin/src/screens/Users.tsx apps/admin/src/screens/Users.test.tsx apps/admin/src/components/Sidebar.tsx apps/admin/src/App.tsx apps/admin/src/styles.css
+git commit -m "feat(admin): Gebruikers screen (list, create, role, password, deactivate)"
+```
+
+---
+
+## Final verification (after all tasks)
+
+- [ ] `yarn workspace @solelog/api test` — all green (incl. `admin-users`, regression `admin`/`report`/`export`).
+- [ ] `yarn workspace @solelog/admin test` — all green (incl. `Users`).
+- [ ] `yarn workspace @solelog/api typecheck` && `yarn workspace @solelog/admin typecheck` — clean.
+- [ ] `yarn workspace @solelog/admin build` — succeeds.
+- [ ] `npx oxlint` — clean.
+- [ ] `git log --oneline` shows six task commits.
