-- Playbook: Full-Spectrum Incident Lifecycle (Zelfire SOC Terms)
-- Intent: Demonstrates 'signal', 'correlate', 'rollback', and 'postmortem'. Moves from the first sign of trouble to a full system recovery and automated lesson extraction.
-- Infrastructure: Zelfire XDR, Linux Configuration, Rosecoin, Slack, Jira.
-- Note: 'rollback' is the ultimate safety net for configuration-based attacks.

-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check OperationalLifecycleEnforcement
  
  -- Trigger Gate: Zelfire identifies a suspicious 'signal' (unauthorized /etc/passwd change)
  ⚠️ when signal_suspicious_config_change
    
    🔹 set target_node: String = event.hostname
    🔹 set change_hash: SHA256 = event.new_file_hash
    
    🚨 alert warning message "SIGNAL DETECTED: Unauthorized config change on {target_node}. Building the story..."

    -- ============================================================================
    -- 3. THE ANALYTICAL LAYER (correlate & story)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Correlate this signal with recent login events and network spikes
      🔹 set active_story: story = zelfire correlate signals for target_node within MAX_STORY_DWELL
      
      -- Action 2: Determine if the story represents a malicious exploit
      ⚠️ when active_story.classification == "MALICIOUS"
        
        🚨 alert critical message "STORY CONFIRMED: Unauthorized persistence attempt on {target_node}. Initiating containment."

        -- ============================================================================
        -- 4. THE KINETIC LAYER (contain & rollback)
        -- ============================================================================
        -- Action 3: Contain the host at the network layer
        ☁️ zelfire contain target_node
        
        -- Action 4: Rollback the configuration to the last 'Golden State'
        -- This effectively undoes the attacker's persistence mechanism.
        ☁️ linux rollback config "/etc/passwd" to "latest-valid-checkpoint"
        
        -- Action 5: Respond by resetting all associated admin credentials
        ☁️ iam user event.acting_user lock
        
        -- Action 6: Notify the IR Team
        📡 notify slack channel IR_CHANNEL message "🕵️‍♂️ *Zelfire Story Resolved* \n*Target:* `{target_node}` \n*Status:* `CONTAINED` \n*Action:* Rollback successful. Attacker persistence removed. Credential locked."

        -- ============================================================================
        -- 5. THE CLOSURE LAYER (closeout & postmortem)
        -- ============================================================================
        -- Action 7: Perform the Closeout
        ☁️ ticket closeout event.case_id resolution "Auto-Rollback and Containment"
        
        -- Action 8: Generate the Postmortem and extract lessons
        -- This automatically updates the 'zelfire' engine to watch for this specific pattern.
        🔹 set lesson_learned: Object = zelfire postmortem for active_story
        
        ☁️ zelfire automate lesson_learned.pattern_match -- "Immunizing" the fleet
