+# E2E Tests for Publication Authorisation (VIBE-247)
+
+## Overview
+Created comprehensive end-to-end tests to verify role-based and provenance-based authorization for publications based on sensitivity levels.
+
+**Test File:** `e2e-tests/tests/publication-authorisation.spec.ts`
+
+## Test Coverage
+
+### 1. Unauthenticated Users (PUBLIC access only)
+- ✅ Should only see PUBLIC publications
+- ✅ Should not see CLASSIFIED Civil and Family publications
+- ✅ Should redirect to sign-in or show 403 when trying to directly access CLASSIFIED publications
+
+### 2. CFT IDAM Authenticated Users (VERIFIED role with CFT provenance)
+- ✅ Should see PUBLIC, PRIVATE, and CLASSIFIED CFT publications
+- ✅ Should be able to access CLASSIFIED Civil and Family Daily Cause List
+- ✅ Should see PRIVATE publications
+- ✅ Should maintain access after navigation and page reload
+- ✅ Should lose access to CLASSIFIED publications after logout
+
+### 3. Provenance-based Filtering for CLASSIFIED Publications
+- ✅ CFT user should see CFT CLASSIFIED publications
+- ✅ Should verify CLASSIFIED publications match user provenance (no 403 errors)
+
+### 4. Edge Cases and Error Handling
+- ✅ Should handle missing sensitivity level (defaults to CLASSIFIED)
+- ✅ Should show appropriate error when accessing restricted publication directly
+- ✅ Should handle invalid locationId gracefully
+
+### 5. Accessibility Compliance
+- ✅ Authenticated summary page should be accessible
+- ✅ All publication links should have accessible text
+
+## Test Scenarios
+
+### Scenario 1: Unauthenticated User Journey
+```
+1. Navigate to /summary-of-publications?locationId=3
+2. Verify only PUBLIC publications are visible
+3. Verify CLASSIFIED publications are filtered out
+4. Try to directly access CLASSIFIED publication URL
+5. Verify 403/404 error or redirect to sign-in
+```
+
+### Scenario 2: CFT Verified User Journey
+```
+1. Login with CFT IDAM credentials
+2. Navigate to /summary-of-publications?locationId=3
+3. Verify CFT user sees more publications than public user
+4. Click on Civil and Family Daily Cause List (CLASSIFIED CFT)
+5. Verify access is granted (no 403 error)
+6. Navigate away and back
+7. Verify access persists
+8. Logout
+9. Verify access is revoked
+```
+
+### Scenario 3: Provenance Matching
+```
+1. Login as CFT user (provenance: "CFT")
+2. Navigate to summary page
+3. Verify CFT CLASSIFIED publications are visible
+4. Click on CFT publication
+5. Verify successful access (no error)
+6. Verify Crime CLASSIFIED publications are NOT visible (different provenance)
+```
+
+## Test Data Requirements
+
+### Location ID 3
+- Should have publications with different sensitivity levels:
+  - PUBLIC publications (visible to all)
+  - PRIVATE publications (visible to verified users)
+  - CLASSIFIED publications with CFT provenance (visible to CFT users only)
+
+### Test Accounts
+- **CFT_VALID_TEST_ACCOUNT**: CFT IDAM account with VERIFIED role and CFT provenance
+- **CFT_VALID_TEST_ACCOUNT_PASSWORD**: Password for CFT test account
+
+### Artefact IDs
+- Tests use actual artefactIds from the database
+- One specific test uses: `a4f06ae6-399f-4207-b676-54f35ad908ed` (from debug logs)
+
+## Running the Tests
+
+```bash
+# Run all E2E tests
+yarn test:e2e
+
+# Run only publication authorization tests
+yarn test:e2e publication-authorisation
+
+# Run with UI mode for debugging
+yarn test:e2e --ui publication-authorisation
+```
+
+## Environment Variables Required
+
+```bash
+# CFT IDAM credentials
+CFT_VALID_TEST_ACCOUNT=pip-cft-valid-test-account@hmcts.net
+CFT_VALID_TEST_ACCOUNT_PASSWORD=<password>
+
+# Enable CFT IDAM
+ENABLE_CFT_IDAM=true
+```
+
+## Test Results Expected
+
+### Before Fix (Security Bug):
+- ❌ CFT users would NOT see CLASSIFIED Civil and Family publications
+- ❌ Provenance mismatch (`"CFT"` vs `"CFT_IDAM"`)
+- ❌ Tests would fail
+
+### After Fix:
+- ✅ CFT users CAN see CLASSIFIED Civil and Family publications
+- ✅ Provenance matching works correctly (`"CFT"` === `"CFT"`)
+- ✅ All tests should pass
+
+## Integration with Existing Tests
+
+These new E2E tests complement the existing test suite:
+
+1. **Unit Tests** (`libs/publication/src/authorisation/*.test.ts`)
+   - Test individual functions
+   - Test access logic in isolation
+   - 72 tests covering all scenarios
+
+2. **E2E Tests** (this file)
+   - Test full user journey
+   - Test authentication flow integration
+   - Test actual publication filtering in UI
+   - ~20 tests covering real-world scenarios
+
+## Accessibility Considerations
+
+All E2E tests verify:
+- Publications are accessible to screen readers
+- Links have meaningful text
+- No accessibility violations for authenticated users
+- Error messages are clear and bilingual
+
+## Known Limitations
+
+1. Tests assume CFT IDAM is configured and available
+2. Tests require specific test data in database (locationId=3 with mixed sensitivity publications)
+3. Some tests check for flexible error handling (403/404/sign-in redirect) as implementation may vary
+
+## Future Enhancements
+
+Potential additions for comprehensive coverage:
+- [ ] E2E tests for CRIME IDAM users (when available)
+- [ ] E2E tests for Local/CTSC admin users (SSO)
+- [ ] E2E tests for System Admin users
+- [ ] Cross-provenance blocking tests (CFT user trying to access CRIME CLASSIFIED)
+- [ ] Performance tests for filtering large publication lists

+# VIBE-247: Authenticate Publications Based on Sensitivity Level - Technical Plan
+
+## Technical Approach
+
+This ticket implements role-based and provenance-based authorisation for publications (artefacts) based on their sensitivity level. The system already has the foundational pieces: sensitivity levels on artefacts, user provenance tracking, and role-based middleware. The implementation extends the existing authorisation middleware to handle publication-specific access rules.
+
+The approach uses a functional authorisation service that evaluates whether a user can access a publication based on: (1) their authentication status and role, (2) the publication's sensitivity level, and (3) provenance matching for classified lists. Access control is enforced through middleware that filters publications in list views and blocks unauthorized direct access. Local and CTSC admins receive special handling - they can view metadata and delete Private/Classified publications but cannot access the actual list data.
+
+A key architectural decision is to keep authorisation logic in a separate service module that can be tested independently and reused across page controllers, API endpoints, and admin functions. The existing artefact model already contains the required fields (sensitivity, provenance), but we need to add list type provenance lookups to validate classified access.
+
+## Implementation Details
+
+### Key Files/Modules to Create
+
+- `libs/publication/src/authorisation/service.ts` - Core authorisation logic
+  - `canAccessPublication(user, artefact, listType)` - Main authorisation function
+  - `canAccessPublicationData(user, artefact, listType)` - Check if user can see actual list data
+  - `canAccessPublicationMetadata(user, artefact)` - Check if user can see metadata only
+  - `filterAccessiblePublications(user, artefacts, listTypes)` - Filter list of publications
+
+- `libs/publication/src/authorisation/middleware.ts` - Express middleware
+  - `requirePublicationAccess()` - Middleware to protect individual publication routes
+  - `requirePublicationDataAccess()` - Middleware to ensure user can view actual data (not just metadata)
+
+- `libs/publication/src/authorisation/service.test.ts` - Comprehensive unit tests for authorisation logic
+
+### Files to Modify
+
+- `libs/publication/src/index.ts` - Export new authorisation functions
+- `libs/public-pages/src/pages/summary-of-publications/index.ts` - Filter publications by user access
+- `libs/public-pages/src/pages/publication/[id].ts` - Add authorisation check
+- `libs/list-types/civil-and-family-daily-cause-list/src/pages/index.ts` - Add authorisation check (and similar for other list type pages)
+- `libs/admin-pages/src/pages/remove-list-search-results/index.ts` - Show all publications to admins but indicate access restrictions
+- `libs/admin-pages/src/pages/remove-list-confirmation/index.ts` - Allow admins to delete regardless of sensitivity
+
+### Database Schema Changes
+
+**No schema changes required.** The existing schema already has:
+- `artefact.sensitivity` - Publication sensitivity level
+- `artefact.provenance` - Publication source system
+- `artefact.list_type_id` - Links to list type (which has provenance)
+- `user.user_provenance` - User authentication source
+- `user.role` - User role
+
+The list type provenance is already available through `mockListTypes` and will be used to validate classified access.
+
+### API Endpoints
+
+No new API endpoints needed. Authorization will be added to existing endpoints:
+- Page routes that display publications (GET handlers)
+- Admin routes for publication management
+
+## Error Handling & Edge Cases
+
+- **Unauthenticated users accessing Private/Classified** - Redirect to login with return URL
+- **Authenticated user without proper role** - Show 403 or redirect to appropriate dashboard
+- **Verified user accessing Classified without matching provenance** - Show 403 error page
+- **List type not found** - Treat as inaccessible (fail closed)
+- **User provenance doesn't match any list type provenance** - Block access to classified lists
+- **Local/CTSC admin attempting to view list data** - Show metadata only page or warning message
+- **System admin** - Full access to all publications regardless of sensitivity
+- **Public users** - Only see PUBLIC sensitivity publications
+- **Missing sensitivity field on artefact** - Treat as CLASSIFIED (most restrictive, fail closed)
+- **Malformed user session** - Redirect to login
+
+## Acceptance Criteria Mapping
+
+| AC | Implementation |
+|---|---|
+| AC1: Sensitivity level during upload | Already exists - artefact model has sensitivity field |
+| AC2: Public accessible to all | `canAccessPublication` returns true for PUBLIC for all users |
+| AC3: Private accessible to verified | `canAccessPublication` checks user.role is not undefined (authenticated/verified) |
+| AC4: Classified accessible with provenance match | `canAccessPublication` checks userProvenance matches listType.provenance |
+| AC5: Validation using user provenance | Authorization service uses UserProfile.provenance from session |
+| AC6: Parent-child relationship hierarchy | Implemented through USER_ROLES constants and role checking logic |
+| AC7: System admin full access | `canAccessPublication` returns true for SYSTEM_ADMIN role |
+| AC8: Verified user classified check | `canAccessPublication` checks provenance match for CLASSIFIED |
+| AC9: Local/CTSC admin metadata only | `canAccessPublicationData` returns false, separate metadata view implemented |
+| AC10: Public users only PUBLIC | `canAccessPublication` returns false for unauthenticated on PRIVATE/CLASSIFIED |
+
+## Open Questions
+
+1. Should we display a message to users explaining why they cannot see certain publications, or silently filter them from lists?
+   - **Recommendation**: Silent filtering in list views, explicit 403 page when directly accessing
+
+2. For Local/CTSC admins viewing metadata, what specific fields should they see? (e.g., list type, content date, display dates, but not case details)
+   - **Recommendation**: Show all artefact metadata (location, dates, sensitivity) but not the JSON payload
+
+3. Should B2C verified users have automatic access to all provenances for classified lists, or should we track their specific provenance?
+   - **Recommendation**: Based on permissions matrix, B2C users should have access to all classified lists (provenance check only applies to differentiate between B2C, CFT_IDAM, CRIME_IDAM users)
+
+4. How should we handle publications where the list type provenance doesn't match any known user provenance values?
+   - **Recommendation**: Fail closed - treat as inaccessible unless user is SYSTEM_ADMIN

+# Code Review: VIBE-247 - Authenticate Publications Based on Sensitivity Level
+
+## Summary
+
+This ticket implements role-based and provenance-based authorisation for publications based on their sensitivity levels (PUBLIC, PRIVATE, CLASSIFIED). The implementation includes a well-structured authorisation service module with comprehensive unit tests, middleware for protecting routes, and integration into existing publication pages.
+
+The core authorisation logic follows security best practices (fail-closed approach) and has excellent test coverage. However, there is a **critical security bug** where Local/CTSC admins can see PRIVATE and CLASSIFIED publications on public pages when they should only see PUBLIC publications.
+
+**Overall Assessment:** NEEDS CHANGES (Critical security bug must be fixed)
+
+---
+
+## 🚨 CRITICAL Issues
+
+### 1. Local/CTSC Admins Can See PRIVATE/CLASSIFIED on Public Pages (SECURITY BUG)
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/service.ts`
+**Lines:** 34-37
+
+**Problem:** The `canAccessPublication()` function incorrectly returns `true` for Local/CTSC admins on PRIVATE and CLASSIFIED publications:
+```typescript
+// Local and CTSC admins can access metadata but handled separately
+if (METADATA_ONLY_ROLES.includes(user.role as any)) {
+  return true; // They can access for metadata purposes
+}
+```
+
+This causes Local/CTSC admins to see PRIVATE and CLASSIFIED publications on the public `summary-of-publications` page (libs/public-pages/src/pages/summary-of-publications/index.ts:46), which uses `filterAccessiblePublications()`.
+
+**Impact:** **CRITICAL SECURITY VULNERABILITY** - Local/CTSC admins can see sensitive publications they should not have access to on public-facing pages. This violates AC9.
+
+**Correct Behavior:**
+- Local/CTSC admins should ONLY see PUBLIC publications on public pages (summary-of-publications)
+- Local/CTSC admins CAN see all publications in admin pages (remove-list-search-results) for deletion purposes
+- Admin pages use `requireRole` middleware and fetch publications directly, bypassing `canAccessPublication()`
+
+**Solution:** Remove lines 34-37 from `canAccessPublication()`. Admin pages don't rely on this function (they use `requireRole` + direct database queries), so removing these lines will:
+1. ✅ Fix public pages: Local/CTSC admins will only see PUBLIC
+2. ✅ Admin pages continue working: They bypass access checks entirely via `requireRole`
+3. ✅ Direct URL access to PRIVATE/CLASSIFIED will be properly blocked by `requirePublicationAccess()` middleware
+
+---
+
+### 2. Missing 403 Error Template
+**File:** Multiple locations (middleware.ts, list type pages)
+**Lines:**
+- `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/middleware.ts:34`
+- `/Users/kian.kwa/IdeaProjects/cath-service2/libs/list-types/civil-and-family-daily-cause-list/src/pages/index.ts:51`
+
+**Problem:** The code attempts to render `errors/403` template but this file does not exist in the codebase. Only `400.njk`, `404.njk`, and `500.njk` exist in `libs/web-core/src/views/errors/`.
+
+**Impact:** Runtime errors when unauthorised users attempt to access restricted publications. The application will fail to render the 403 error page, resulting in a broken user experience.
+
+**Solution:** Create `/Users/kian.kwa/IdeaProjects/cath-service2/libs/web-core/src/views/errors/403.njk` template following the same pattern as other error pages. Include both English and Welsh content. Example structure:
+
+```nunjucks
+{% extends "layouts/default.njk" %}
+
+{% block pageTitle %}{{ title }} - {{ serviceName }}{% endblock %}
+
+{% block content %}
+  <div class="govuk-grid-row">
+    <div class="govuk-grid-column-two-thirds">
+      <h1 class="govuk-heading-xl">{{ title }}</h1>
+      <p class="govuk-body">{{ message }}</p>
+    </div>
+  </div>
+{% endblock %}
+```
+
+---
+
+### 3. Type Safety Issue with Role/Provenance Checking
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/service.ts`
+**Lines:** 35, 41, 46, 75, 100
+
+**Problem:** Code uses `as any` type assertions when checking roles and provenance:
+```typescript
+if (METADATA_ONLY_ROLES.includes(user.role as any)) {
+if (VERIFIED_USER_PROVENANCES.includes(user.provenance as any)) {
+```
+
+**Impact:** Defeats TypeScript's type safety, potential runtime errors if user.role or user.provenance have unexpected values.
+
+**Solution:** Since `UserProfile.role` and `UserProfile.provenance` are optional strings, perform proper type guards:
+```typescript
+if (user.role && METADATA_ONLY_ROLES.includes(user.role as typeof METADATA_ONLY_ROLES[number])) {
+```
+
+Or better, define proper types for valid roles and provenance values and use them in UserProfile interface.
+
+---
+
+## ⚠️ HIGH PRIORITY Issues
+
+### 1. Duplicate Database Queries in Middleware
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/middleware.ts`
+**Lines:** 21-23
+
+**Problem:** The middleware fetches the artefact from the database to check permissions, then the page handler likely fetches it again. This is inefficient.
+
+**Impact:** Unnecessary database load, slower response times, potential for race conditions if data changes between checks.
+
+**Recommendation:** Consider attaching the fetched artefact to `req` so the handler can reuse it:
+```typescript
+// In middleware
+req.artefact = artefact; // Add to Request type augmentation
+
+// In handler
+const artefact = req.artefact || await prisma.artefact.findUnique(...);
+```
+
+---
+
+### 2. Missing Audit Logging for Access Denials
+**Files:** Middleware and service files
+
+**Problem:** When access is denied, there's no audit trail. Security-sensitive applications should log who attempted to access what and why they were denied.
+
+**Impact:** Cannot track potential security breaches, unauthorised access attempts, or debug permission issues.
+
+**Recommendation:** Add structured logging for access denials:
+```typescript
+if (!canAccessPublication(user, artefact, listType)) {
+  logger.warn('Publication access denied', {
+    userId: user?.id,
+    userRole: user?.role,
+    userProvenance: user?.provenance,
+    artefactId: publicationId,
+    sensitivity: artefact.sensitivity,
+    timestamp: new Date().toISOString()
+  });
+  return res.status(403).render("errors/403");
+}
+```
+
+---
+
+### 3. Error Information Leakage via Console.error
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/middleware.ts`
+**Lines:** 38, 85
+
+**Problem:** Using `console.error` to log errors may expose sensitive information in production logs and doesn't follow structured logging best practices.
+
+**Impact:** Potential information disclosure, poor log management, difficult to monitor in production.
+
+**Recommendation:** Use a proper logger with appropriate log levels:
+```typescript
+logger.error('Error checking publication access', {
+  error: error.message,
+  publicationId,
+  userId: req.user?.id
+});
+```
+
+---
+
+### 4. Hard-coded Error Message in Production
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/admin-pages/src/pages/remove-list-confirmation/index.ts`
+**Line:** 126
+
+**Problem:** Error message is hard-coded in English only within the code:
+```typescript
+text: "An error occurred while removing content. Please try again later."
+```
+
+**Impact:** Breaks Welsh language support, inconsistent with the rest of the application's i18n approach.
+
+**Recommendation:** Move this to the lang object (en.ts and cy.ts files).
+
+---
+
+## 💡 SUGGESTIONS
+
+### 1. Test Coverage Enhancement
+**Current:** Unit tests are comprehensive (58 tests for service, 14 for middleware), but no E2E tests added despite tasks.md claiming they were done.
+
+**Recommendation:** Add E2E tests to verify the full user journey:
+- Unauthenticated user trying to access PRIVATE publication
+- Verified user with matching provenance accessing CLASSIFIED
+- Local admin attempting to view PRIVATE list data
+- System admin accessing all publications
+- **Local/CTSC admin on summary-of-publications page (should only see PUBLIC)**
+
+---
+
+### 2. Performance Optimization - Caching List Types
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/publication/src/authorisation/service.ts`
+**Line:** 122
+
+**Problem:** `filterAccessiblePublications` iterates through all artefacts and performs a `find` on list types for each one.
+
+**Impact:** O(n*m) complexity, could be slow for large datasets.
+
+**Recommendation:** Convert listTypes array to a Map for O(1) lookups:
+```typescript
+const listTypeMap = new Map(listTypes.map(lt => [lt.id, lt]));
+return artefacts.filter((artefact) => {
+  const listType = listTypeMap.get(artefact.listTypeId);
+  return canAccessPublication(user, artefact, listType);
+});
+```
+
+---
+
+### 3. Consistent Error Handling Pattern
+**File:** `/Users/kian.kwa/IdeaProjects/cath-service2/libs/list-types/civil-and-family-daily-cause-list/src/pages/index.ts`
+**Lines:** 47-59
+
+**Problem:** Error handling for authorisation check is done inline with custom English/Welsh messages, while the middleware uses a separate approach.
+
+**Impact:** Inconsistent error messages, duplicate code.
+
+**Recommendation:** Standardise on using the middleware for all authorisation checks, or create a shared error message utility.
+
+---
+
+## ✅ Positive Feedback
+
+### 1. Excellent Test Coverage
+The authorisation service has comprehensive unit tests covering all sensitivity levels, user roles, and edge cases including:
+- All user role combinations
+- Provenance matching for CLASSIFIED publications
+- Missing data scenarios (fail-closed approach)
+- Edge cases like missing sensitivity fields
+
+This demonstrates good testing practices and gives confidence in the core logic.
+
+---
+
+### 2. Security-First Design
+The implementation follows security best practices:
+- Fail-closed approach (defaults to CLASSIFIED if sensitivity missing)
+- Explicit permission checks rather than blacklisting
+- Separation of "access" vs "data access" for metadata-only scenarios
+- Provenance matching for CLASSIFIED lists
+
+---
+
+### 3. Clean Separation of Concerns
+The architecture properly separates:
+- Business logic (service.ts)
+- HTTP handling (middleware.ts)
+- Pure functions for easy testing
+- Clear function naming that describes intent
+
+This makes the code maintainable and easy to understand.
+
+---
+
+### 4. Proper TypeScript Usage
+- Comprehensive type definitions
+- Type imports where appropriate
+- Minimal use of `any` (only in the noted issues)
+- Good interface definitions for test helpers
+
+---
+
+### 5. Welsh Language Support
+Error messages in middleware include both English and Welsh translations, maintaining consistency with the rest of the application.
+
+---
+
+## Test Coverage Assessment
+
+### Unit Tests: EXCELLENT (✅)
+- **Service tests:** 58 tests covering all functions and scenarios
+- **Middleware tests:** 14 tests covering happy paths and error conditions
+- **Edge cases:** Well covered (missing fields, null users, unknown list types)
+- **Coverage:** High coverage on business logic
+
+### Integration Tests: PARTIAL (⚠️)
+- Publication list filtering tested via unit tests
+- No tests for the complete flow from HTTP request to authorisation decision
+- No tests for session/authentication integration
+
+### E2E Tests: MISSING (❌)
+- Task list claims E2E tests were added but none found
+- No Playwright tests for different user roles accessing publications
+- No tests for the complete user journey
+- **Missing critical test:** Local/CTSC admin on summary page should only see PUBLIC
+
+### Accessibility Tests: NOT APPLICABLE
+- New error pages need a11y testing once 403.njk is created
+- Existing pages not modified so no new a11y concerns
+
+---

+
+## Overall Assessment
+
+**Status:** NEEDS CHANGES (Critical Security Bug)
+
+The core authorisation logic is well-designed, thoroughly tested, and follows security best practices. However, there is a **critical security vulnerability** in AC9 implementation:
+
+**Critical Issues:**
+1. **Security Bug:** Lines 34-37 in `canAccessPublication()` allow Local/CTSC admins to see PRIVATE and CLASSIFIED publications on the public summary-of-publications page
+2. Missing 403 error template will cause runtime errors
+3. Type safety compromised with `as any` usage
+
+The fix for issue #1 is straightforward: remove lines 34-37. Admin pages use `requireRole` middleware and don't rely on `canAccessPublication()`, so this change will not affect admin functionality.
+
+Once the security bug is fixed, the missing 403 template is created, and type safety issues are addressed, the implementation will be production-ready. The test coverage is excellent and demonstrates careful consideration of edge cases and security scenarios.
+
+**After fixes, this will satisfy all 10 acceptance criteria.**

+# VIBE-247: Authenticate Publications Based on Sensitivity Level
+
+## Problem Statement
+Every list published in CaTH is assigned a sensitivity level which indicates which user group the publication should be made available to. This ticket covers the authentication of publications based on the sensitivity level.
+
+## User Story
+**AS A** System
+**I WANT** to Authenticate publications assigned the 'Classified' sensitivity level in CaTH
+**SO THAT** these publication files are only available to CaTH Users with the required clearance levels
+
+## Acceptance Criteria
+
+1. Each uploaded publication file in CaTH must have an indicated sensitivity level indication during the uploading process such that each list type is linked to a specific sensitivity level
+
+2. **Public Sensitivity Level**: Where a Publication file is assigned the 'Public' sensitivity level, then the Publication file will be available to all users
+
+3. **Private Sensitivity Level**: Where a Publication file is assigned the 'Private' sensitivity level, then the Publication file will be available to only all verified users (e.g. Legal professionals and media)
+
+4. **Classified Sensitivity Level**: Where a Publication file is assigned the 'Classified' sensitivity level, then the Publication file will be available to only verified users who are in a group eligible to view that list (e.g. SJP press list available to Media)
+
+5. The validation logic for each sensitivity level will be inferred by using the user provenance stored against each user in the database to determine the accessibility of user groups when any file is published in CaTH
+
+6. The data classification level should be configured in the user table using a 'Parent Child relationship' as the Rule Hierarchy. This should follow the User Provenance - User Role - Sensitivity levelling
+
+7. System admin can see Public, Private, Classified
+
+8. If it is a verified user and list is classified, user provenance of the user will be compared with list type provenance
+
+9. For Local and CTSC admin, they should be able to delete and view metadata for private and classified publication but not able to see the actual list data (only can access list metadata for the classified list)
+
+10. Public users can only access Public Lists. They must not be allowed to view private and classified lists
+
+## Permissions Matrix
+
+| User Provenance | User Role | Accessible Sensitivity Levels |
+|----------------|-----------|-------------------------------|
+| B2C | Verified | Public, Private, Classified |
+| SSO | System Admin | Public, Private, Classified |
+| SSO | Local Admin, CTSC Admin | Public (metadata only for Private/Classified) |
+| CFT IdAM | Verified | Public, Private, Classified |
+| Crime IdAM | Verified | Public, Private, Classified |
+| Public | Public | Public |
+
+## Key Requirements
+
+### Access Control Rules
+- **System Admin (SSO)**: Full access to all sensitivity levels
+- **Verified Users (B2C, CFT IdAM, Crime IdAM)**: Access to Public, Private, and Classified lists (Classified requires matching provenance)
+- **Local Admin / CTSC Admin (SSO)**:
+  - Can view Public lists (full access)
+  - Can view metadata and delete Private/Classified lists
+  - Cannot view actual list data for Private/Classified
+- **Public Users**: Only Public lists
+
+### Classified List Logic
+- For Classified lists, verify user provenance matches the list type provenance
+- Only verified users with matching provenance can access the actual list data
