-- 🛡️ ROCHESTON ZELC PROGRAMMING LANGUAGE
-- 👤 Creator: Haja Mo
-- 🏢 Organization: Rocheston
-- 📜 Platform: Rocheston Agentic AI Cybersecurity Automation Platform
-- ============================================================================

-- Playbook: Forensic Preservation & Investigation (DFIR Keywords)
-- Intent: Demonstrates 'evidence_bag', 'chain_of_custody', 'triage', and 'notarize'. 
-- Automates the legal-grade collection of host and cloud artifacts.
-- Infrastructure: Forensic S3 Vault, Volatility Engine, Rosecoin, AINA.
-- Note: 'preserve' is the first action to prevent metadata tampering.

-- 1. CONFIGURATION GOVERNORS (Strongly Typed)
-- ============================================================================
⚙️ keep FORENSIC_VAULT: String = "s3://rocheston-forensic-storage/case-2026-03-11"
⚙️ keep CASE_ID: String = "INCIDENT-DFIR-7892"

-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check ForensicArtifactInvestigation
  
  -- Trigger Gate: A high-severity breach is confirmed on a sensitive VM
  ⚠️ when technical_breach_confirmed for "Payment-Processor-01"
    
    🔹 set target_host: String = event.hostname
    🔹 set investigator: String = "AINA-Forensics-Module"
    
    🚨 alert info message "DFIR: Commencing forensic triage and artifact acquisition for {CASE_ID}."

    -- ============================================================================
    -- 3. THE PRESERVATION LAYER (preserve, acquire, triage)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Create a secure 'evidence_bag' for this case
      -- Voice-friendly: "Forensics create evidence_bag..."
      🔹 set bag: evidence_bag = forensics create_bag for CASE_ID
      
      -- Action 2: Perform rapid 'triage' to identify 'host_artifacts'
      -- Collects volatile memory and current network connections first.
      ☁️ forensics preserve memory on target_host
      ☁️ forensics acquire host_artifacts ["MFT", "Registry", "Prefetch"] from target_host
      
      -- Action 3: Collect 'cloud_artifacts' for identity correlation
      ☁️ forensics acquire cloud_artifacts ["CloudTrail", "VPCFlowLogs"] from "us-east-1"
      
      -- Action 4: Sweep for 'email_artifacts' and 'browser_artifacts' to find the entry vector
      ☁️ forensics collect email_artifacts for "admin-user@rocheston.io" since "24h"

      -- ============================================================================
      -- 4. THE INTEGRITY LAYER (integrity_check, hash_verify, signed_evidence)
      -- ============================================================================
      -- Action 5: Generate an integrity 'hash' for every collected artifact
      -- Voice-friendly: "Forensics hash_verify..."
      🔹 set artifact_hash: hash = forensics hash_verify bag HASH_ALGO
      
      -- Action 6: Secure the 'chain_of_custody' by signing the metadata
      ☁️ forensics sign_evidence bag with "ROCHESTON-DFIR-KEY-001"
      
      -- Action 7: Verify the integrity of the 'evidence_bag' before final storage
      ⚠️ when forensics integrity_check bag == false
         🚨 alert critical message "FORENSIC FAIL: Integrity check failed for {CASE_ID}. Possible tampering."

      -- ============================================================================
      -- 5. THE NOTARIZATION LAYER (notarize, provenance, archive)
      -- ============================================================================
      -- Action 8: Notarize the evidence on Rosecoin
      -- This provides a timestamped, immutable record of 'provenance'.
      -- Voice-friendly: "Notarize evidence..."
      ⛓️ rosecoin notarize bag.metadata.hash with "Public-Auditor-Key"
      
      -- Action 9: Archive the 'evidence_bag' to the encrypted Forensic Vault
      ☁️ storage archive bag to FORENSIC_VAULT with "WORM-Policy"

      -- Action 10: Notify the Legal and Security leadership
      📡 notify slack channel "#dfir-evidence-log" message "⚖️ *Forensic Preservation Complete* \n*Case:* `{CASE_ID}` \n*Artifacts:* Host, Cloud, and Email. \n*Chain of Custody:* Verified and Signed. \n*Provenance:* Notarized on Rosecoin."
