-- Playbook: Secure Software Supply Chain (DevSecOps Keywords)
-- Intent: Demonstrates 'slsa', 'sbom', 'sigstore', and 'iac_scan'. 
-- Prevents "Dependency Confusion" and "Tainted Build" attacks.
-- Infrastructure: GitHub Actions/GitLab CI, Sigstore (Cosign), Trivy, Terraform.
-- Note: 'hermetic_build' ensures the environment has no external network access during compilation.

-- 1. CONFIGURATION GOVERNORS (Strongly Typed)
-- ============================================================================
⚙️ keep MIN_SLSA_LEVEL: Integer = 3
⚙️ keep ALLOWED_LICENSES: Array = ["MIT", "Apache-2.0", "BSD-3-Clause"]
⚙️ keep SCAN_ENGINE: String = "semgrep"

-- 2. THE ENTRY POINT (The Check Block)
-- ============================================================================
🔥 check SupplyChainIntegrityGate
  
  -- Trigger Gate: A new 'pull_request' is opened involving 'yaml' or 'tf' files
  ⚠️ when pipeline_commit_detected
    
    🔹 set artifact_id: String = event.commit_sha
    🔹 set iac_files: Array = event.changed_files where extension in ["tf", "yaml", "json"]
    
    🚨 alert info message "DEVSECOPS: Commencing Supply Chain validation for artifact {artifact_id}."

    -- ============================================================================
    -- 3. THE SCANNING ECOSYSTEM (sast, sca, iac_scan, secrets_scan)
    -- ============================================================================
    ⚡ do
      
      -- Action 1: Run Infrastructure as Code (IaC) scan on Terraform/Helm files
      -- Voice-friendly: "AINA scan IaC..."
      ☁️ terraform iac_scan using "checkov" on iac_files
      ☁️ helm kustomize scan using "tfsec"
      
      -- Action 2: Perform 'secrets_scan' and 'sast' (CodeQL/Semgrep)
      ☁️ codeql scan language "golang"
      ☁️ semgrep scan --config "p/security-audit"
      
      -- Action 3: Generate and scan the Software Bill of Materials (SBOM)
      -- Voice-friendly: "Syft generate SBOM..."
      🔹 set current_sbom: sbom = syft generate sbom for artifact_id
      ☁️ trivy sca scan current_sbom --severity "HIGH,CRITICAL"

      -- ============================================================================
      -- 4. THE INTEGRITY LAYER (slsa, sigstore, cosign, attestation)
      -- ============================================================================
      -- Action 4: Verify 'build_provenance' using Sigstore/Rekor
      -- This ensures the build happened in a trusted, 'hermetic_build' environment.
      🔹 set provenance: build_provenance = sigstore verify_provenance artifact_id
      
      -- Action 5: Check SLSA Level compliance
      ⚠️ when provenance.slsa_level < MIN_SLSA_LEVEL
         🚨 alert critical message "INTEGRITY FAIL: Artifact {artifact_id} only meets SLSA Level {provenance.slsa_level}."
         ✨ quality_gate block "Failed SLSA Compliance"
      🔴 end
      
      -- Action 6: Keyless signing of the SBOM using Cosign/Fulcio
      ☁️ cosign sign_blob current_sbom --keyless true --identity "build-bot@rocheston.io"

      -- ============================================================================
      -- 5. THE POLICY GATE (license_scan, quality_gate)
      -- ============================================================================
      -- Action 7: Run 'license_scan' to ensure legal compliance
      🔹 set license_report: Object = license_scan artifact_id
      
      ⚠️ when license_report.unapproved_found == true
         🚨 alert warning message "LICENSE ALERT: Prohibited licenses detected in dependencies."
         ✨ policy_gate fail "License Policy Violation"
      🔴 end

      -- Action 8: If all checks pass, provide the 'artifact_attestation'
      ☁️ in_toto create_link_metadata artifact_id status "VERIFIED"
      ☁️ sigstore attest_artifact artifact_id using "in-toto-layout-v1"

      -- Action 9: Notify the DevOps and Security Engineers
      📡 notify slack channel "#supply-chain-security" message "🏗️ *Pipeline Security Passed* \n*Artifact:* `{artifact_id}` \n*SLSA Level:* `{provenance.slsa_level}` \n*SBOM:* Signed & Attested. \n*Status:* Deployment APPROVED."
