+# Test: Agent Availability and Status
+# Run with: bundle exec rails runner script/assignment_v2/test_agent_availability.rb
+#
+# Tests:
+# - Only online agents receive assignments
+# - Offline agents are excluded from assignment pool
+# - When agents go offline mid-assignment, remaining conversations go to online agents
+# - When agents come online, they become eligible for new assignments
+#
+# Key Implementation Details:
+# - inbox.available_agents filters by online status via OnlineStatusTracker
+# - OnlineStatusTracker.update_presence(account_id, 'User', user_id) marks agent as online
+# - OnlineStatusTracker.remove_presence(account_id, 'User', user_id) marks agent as offline
+# - Availability is checked for EACH conversation assignment (not cached for the batch)
+# - This ensures real-time status changes affect assignment within a single job run

+#
+# Key Design Decisions & Fixes:
+#
+# 1. Password Requirements:
+#    - Users require complex passwords: 'Password123!' (uppercase + special char)
+#
+# 2. Unique Naming:
+#    - All entities (inboxes, policies, agents) get unique names using SecureRandom.hex(4)
+#    - Prevents validation errors across multiple test runs
+#
+# 3. Conversation Creation:
+#    - Uses FactoryBot to handle complex associations automatically
+#    - ContactInbox requires source_id (cannot be blank)
+#    - FactoryBot factory handles: contact → contact_inbox → conversation chain
+#
+# 4. Policy Linking:
+#    - RateLimiter reads from inbox.auto_assignment_config (not policy directly)
+#    - link_policy_to_inbox syncs policy settings to inbox config
+#    - Must call inbox.reload after linking to pick up association
+#
+# 5. Redis Access:
+#    - Use Redis::Alfred.keys_count() instead of Redis::Alfred.redis.keys.count
+#    - Use Redis::Alfred.scan_each() instead of Redis::Alfred.redis.keys for cleanup
+#
+# 6. Assignment Job:
+#    - Must use keyword argument: perform_now(inbox_id: id)
+#    - Not positional: perform_now(id) will fail
