+# Per-User Museum & Channel Access Control
+
+**Date:** 2026-04-08  
+**Status:** Approved  
+
+## Overview
+
+Allow admins to restrict client-facing users to specific museums (events) and channels. When a restricted user logs in, the dashboard only shows data and filter options for their allowed scope — enforced at the UI and data layers (client-side). The enforcement is intentional client-side filtering; this is an internal analytics tool and not a security boundary against a determined attacker.
+
+---
+
+## Data Model
+
+### User type (`src/types/index.ts`)
+
+Add two fields to the existing `User` interface (keeping PascalCase to match NocoDB conventions used throughout the codebase):
+
+```typescript
+interface User {
+  Id?: number;
+  Name: string;
+  PIN: string;
+  Role: 'admin' | 'viewer';
+  AllowedMuseums: string; // JSON-serialized string array, e.g. '["Museum A","Museum B"]'
+  AllowedChannels: string; // JSON-serialized string array
+}
+```
+
+Parsed into a runtime shape used in app state:
+
+```typescript
+interface ParsedUser {
+  id: number;
+  name: string;
+  role: 'admin' | 'viewer';
+  allowedMuseums: string[] | null; // [] = unrestricted, null = parse error (show nothing)
+  allowedChannels: string[] | null; // [] = unrestricted, null = parse error (show nothing)
+}
+```
+
+**Convention:** `[]` = full access (admins), `string[]` = restricted to list, `null` = corrupted value (fail-closed: no data shown). Existing users require no migration (missing fields parsed as `[]`).
+
+### NocoDB Users table
+
+Add two new fields:
+- `AllowedMuseums` — Text field, stores JSON string (e.g. `'["Museum A"]'`)
+- `AllowedChannels` — Text field, stores JSON string
+
+Both default to `"[]"` (unrestricted).
+
+---
+
+## Components & Changes
+
+### 1. `src/services/usersService.ts`
+
+- Update `fetchUsers()` to parse `AllowedMuseums` and `AllowedChannels` JSON strings into `string[]`; on parse error return `null` (fail-closed — no data shown to the user)
+- Update `createUser()` to serialize `allowedMuseums`/`allowedChannels` arrays as JSON strings
+- **Add `updateUser(id, fields)`** — new function required (see Prerequisites below)
+
+### 2. `server/src/routes/users.ts` + `nocodbClient.ts`
+
+**Prerequisite:** `updateUser` does not exist yet. Required additions:
+- `nocodbClient.updateRecord(tableId, rowId, fields)` — calls NocoDB `PATCH /api/v2/tables/{tableId}/records`
+- `PUT /api/users/:id` route on the server — validates fields and calls `updateRecord`
+- `updateUser(id, fields)` in `usersService.ts` — calls the new route
+
+### 3. `server/src/routes/auth.ts`
+
+The session object currently stores only `{ name, role, createdAt }`. Extend it to also persist `allowedMuseums` and `allowedChannels` at login time:
+
+```typescript
+// On POST /auth/login — after matching user by PIN:
+session.allowedMuseums = parsedUser.allowedMuseums;
+session.allowedChannels = parsedUser.allowedChannels;
+
+// On GET /auth/check — return alongside existing fields:
+res.json({
+  authenticated: true,
+  name: session.name,
+  role: session.role,
+  allowedMuseums: session.allowedMuseums ?? [],
+  allowedChannels: session.allowedChannels ?? [],
+});
+```
+
+This ensures page reload restores the correct access scope without re-fetching NocoDB.
+
+### 4. `src/App.tsx`
+
+- Store `allowedMuseums` and `allowedChannels` in app state (alongside `userRole`, `userName`)
+- Set them from both the `/auth/login` response and the `/auth/check` response
+- Pass them as props to **both** `Dashboard` and `Comparison` components
+- Also pass `allMuseums` and `allChannels` (unique values extracted from raw `data`) as props to `Settings`
+
+### 5. `src/components/Settings.tsx`
+
+Accept two new props: `allMuseums: string[]` and `allChannels: string[]`.
+
+In the add/edit user form, add two checkbox picker sections (hidden for admin users):
+
+- **Allowed Events** — checkbox list from `allMuseums`
+- **Allowed Channels** — checkbox list from `allChannels`
+
+UI behavior:
+- Empty selection = full access, shown as `"All access"` label
+- Partial selection shown as `"N events"` / `"N channels"` badge
+- Admin users: section hidden, shown as `"Full access (admin)"` static label
+
+### 6. `src/components/Dashboard.tsx`
+
+Accept two new props: `allowedMuseums: string[]` and `allowedChannels: string[]`.
+
+Two enforcement layers applied before any render:
+
+**Layer 1 — Filter options restricted:**
+```typescript
+const visibleMuseums = allowedMuseums.length > 0
+  ? availableMuseums.filter(m => allowedMuseums.includes(m))
+  : availableMuseums;
+
+const visibleChannels = allowedChannels.length > 0
+  ? channels.filter(c => allowedChannels.includes(c))
+  : channels;
+```
+
+**Layer 2 — Data filtered at base:**
+```typescript
+const permissionFilteredData = useMemo(() => {
+  // null = corrupted stored value → show nothing (fail-closed)
+  if (allowedMuseums === null || allowedChannels === null) return [];
+  let d = data;
+  if (allowedMuseums.length > 0)
+    d = d.filter(r => allowedMuseums.includes(r.museum_name));
+  if (allowedChannels.length > 0)
+    d = d.filter(r => allowedChannels.includes(r.channel));
+  return d;
+}, [data, allowedMuseums, allowedChannels]);
+```
+
+Replace `data` with `permissionFilteredData` as the base for all subsequent filtering and chart rendering.
+
+### 7. `src/components/Comparison.tsx`
+
+Apply the same Layer 2 base filter to `Comparison` (same props: `allowedMuseums`, `allowedChannels`). Restricted users must not see unfiltered data on the comparison page.
+
+---
+
+## Auth Flow
+
+```
+User enters PIN
+  → POST /auth/login → server matches user, stores allowedMuseums/allowedChannels in session
+  → App stores them in state, passes to Dashboard + Comparison
+
+Page reload
+  → GET /auth/check → server returns allowedMuseums/allowedChannels from session
+  → App restores state correctly
+```
+
+---
+
+## Edge Cases
+
+| Scenario | Behavior |
+|----------|----------|
+| User has 1 allowed museum | Filter dropdown shows with 1 option only |
+| User has all museums allowed (empty array) | No change from today |
+| Admin user | `allowedMuseums: []`, `allowedChannels: []` — full access |
+| URL param references disallowed museum | Base filter removes it silently |
+| New museum added to data, not in user's list | Not visible to restricted user |
+| JSON parse error on stored value | `null` returned → no data shown (fail-closed) |
+| Page reload | Session restores access lists from server |
+
+---
+
+## Prerequisites (must be built first)
+
+1. `nocodbClient.updateRecord()` method
+2. `PUT /api/users/:id` server route
+3. `updateUser()` in `usersService.ts`
+
+---
+
+## Out of Scope
+
+- District-level access control
+- Role-based permission templates
+- Audit logging of access
+- Server-side data API enforcement
