## Code Review - Re-Review with Latest Commit (fcd0f99) ### Test Results - Test suite run: `bundle exec rspec` - Results: **728 examples, 0 failures, 7 pending** ✅ ### Implementation Now Matches Ticket Requirements **ApplicationController** (`app/controllers/application_controller.rb:5-7`): ```ruby # Require authentication for all controllers by default # API controllers skip this via skip_before_action before_action :require_login ``` - ✅ Unconditional `before_action :require_login` (all controllers protected by default) - ✅ No `ENV['REQUIRE_AUTH']` check (removed) - ✅ No `requires_login?` opt-in method (removed) **SessionsController** (`app/controllers/sessions_controller.rb:4`): ```ruby skip_before_action :require_login, only: [:new, :create] ``` - ✅ Login page skips authentication **API Controllers**: - API controllers inherit from `ActionController::API` (not `ApplicationController`) - Use X-API-Key header authentication - ✅ Not affected by ApplicationController's `require_login` ### Security Review - ✅ Session fixation protection (reset_session after login) - ✅ Rate limiting (5 attempts/hour) - ✅ Password input type for API key field - ✅ Uses existing `Agent.authenticate_by_api_key` pattern - ✅ CSRF protection via Rails form_with ### Spec Coverage - ✅ `spec/features/sessions_spec.rb` (215 lines) - ✅ `spec/requests/sessions_spec.rb` (123 lines) - ✅ `spec/support/authentication_helper.rb` (41 lines) - ✅ All existing feature specs updated with `login_as(agent)` helper ### Decision **PASS** - Implementation matches ticket requirements exactly, all tests pass, comprehensive spec coverage, security best practices followed.
