<CRITICAL_DIRECTIVE> Execute strict AppSec procedural audits and mandate ZERO-TOLERANCE for dummy authentication or authorization logic. </CRITICAL_DIRECTIVE>

<ENTERPRISE_STANDARDS>

1. ZERO Dummy Auth: You are strictly FORBIDDEN from using hardcoded roles (e.g., if user.role == 'admin') or dummy data. You MUST implement industrial-standard Policy-Based Access Control (PBAC), Attribute-Based Access Control (ABAC), or a robust RBAC system backed by actual database relations.
2. Industrial Cryptography: NEVER use mock hashes or plain-text passwords. You MUST integrate production-grade cryptography (e.g., Argon2id, bcrypt, or framework-native secure hashers) and fully implement JWT/Session validation.
3. Strict Schema Fidelity: DO NOT hallucinate User, Role, or Permission tables. You MUST use grep_search to verify the exact database schema or Prisma/TypeORM/SQL models before writing authorization logic. </ENTERPRISE_STANDARDS>

<PROCEDURAL_WORKFLOW>

1. Automated Scanning: Execute gitleaks detect or semgrep scan on your diffs before concluding the security audit. Do not rely solely on visual inspection. If tools are unavailable, explicitly note this in your report.
2. Secret Scanning & Git Hygiene: Ensure all credentials, tokens, and private keys are strictly referenced via environment variables. Run python3 scripts/git_hygiene_guard.py --check to ensure zero untracked secrets or dirty stashes.
3. Boundary Audit: If you added a new input vector (API endpoint, CLI argument), verify that a strict validation schema sits at the immediate boundary.
4. Execution Context: If modifying Dockerfiles or CI workflows, verify that execution privileges are explicitly dropped (USER nonroot).
5. Dependency Audit: Ensure all added packages or base images use strict version pinning (or sha256 digests).
6. Shell Isolation (Terminal-First Security): You are FORBIDDEN from executing global installs (npm i -g, sudo), modifying SSH keys, or running destructive recursive commands (rm -rf /). All shell execution MUST be isolated to the project workspace.
7. Verification & Audit Report: Run python3 scripts/verify.py --execute and output a <security_audit> block confirming these checks are complete. </PROCEDURAL_WORKFLOW>

<L9_STANDARDS>

• Zero Trust: Always sanitize and validate input payloads. Never trust client-side validation.
• Secrets Management: Never hardcode credentials. Always use environment variables or secret managers.
• OWASP Top 10: Protect against SQL Injection, XSS, CSRF, and IDOR by default. </L9_STANDARDS>
