## Code Review ### Test Results - Test suite run: `bundle exec rspec` - Results: 728 examples, **126 failures**, 7 pending - **CRITICAL: 126 test failures caused by authentication breaking existing tests** ### Root Cause Analysis The PR adds `before_action :require_login` to `ApplicationController` with `login_optional?` defaulting to `false`. This means ALL controllers now require authentication, but existing tests were not updated to log in first. ### Failure Categories 1. **Feature specs (67 failures)**: All feature tests redirect to `/login` because they don't authenticate first - spec/features/approvals_spec.rb - spec/features/dashboard_spec.rb - spec/features/debug_dashboard_spec.rb - spec/features/kanban_board_spec.rb - spec/features/multi_terminal_page_spec.rb - spec/features/proposals_spec.rb - spec/features/sessions_page_spec.rb - spec/features/terminal_page_spec.rb - spec/features/ticket_comments_spec.rb - spec/features/ticket_workflow_spec.rb 2. **Request specs (18 failures)**: All request specs now redirect (302) instead of returning content 3. **New authentication spec issues (2 failures)**: - spec/requests/sessions_spec.rb:29 - Uses `session` method incorrectly in request spec - spec/features/sessions_spec.rb:181 - Uses Selenium cookie access incompatible with Cuprite driver 4. **System specs (6 failures)**: Agent session tests also redirect to login ### Files Changed - app/controllers/application_controller.rb - Added require_login before_action - app/controllers/sessions_controller.rb - New controller (63 lines) - app/views/layouts/application.html.haml - Navigation changes - app/views/sessions/new.html.haml - New login view (55 lines) - config/routes.rb - Added login/logout routes - spec/features/sessions_spec.rb - New feature specs (209 lines) - spec/requests/sessions_spec.rb - New request specs (122 lines) ### Required Fixes **OPTION 1: Opt-in Authentication (RECOMMENDED)** Change the default to NOT require login, only require it on specific controllers: ```ruby before_action :require_login, if: :login_required? def login_required? false # Override in controllers that need auth end ``` **OR OPTION 2: Update All Existing Tests** Add `before { login_as(agent) }` helper or similar to all 100+ existing feature/request specs. **ALSO FIX:** 1. spec/requests/sessions_spec.rb:29 - Request specs cannot directly call `session[:key] = value` 2. spec/features/sessions_spec.rb:181 - Use driver-agnostic session check instead of Selenium-specific `manage.cookie` ### Security Notes - Session fixation protection with `reset_session` is good ✓ - Rate limiting on failed attempts is good ✓ - Password-type input field for API key is good ✓ ### Decision **FAIL - Breaking Changes + Spec Issues** This PR adds authentication that breaks 126 existing tests. Before this can be approved: 1. Choose opt-in approach OR update all existing tests to authenticate first 2. Fix the 2 broken tests in the new authentication specs 3. Verify the full test suite passes (0 failures)
