Policy Agent for MCP Architecture

Enhanced compliance and security standards checking for smart contracts.

ARCHITECTURAL NOTE - LAYER 6 + LAYER 7 INTEGRATION:
====================================================
This agent implements both Layer 6 (Policy/Compliance) and Layer 7 (Audit Readiness)
of MIESC's defense-in-depth architecture as an integrated component.

Design Rationale:
- Audit readiness assessment requires access to all compliance data
- Trail of Bits checklist scoring reuses Layer 6 vulnerability classification
- Tight coupling enables efficient cross-standard correlation
- Single audit trail for all compliance and audit evidence (MCP Context Bus)

Layer Separation:
- Layer 6 (Policy/Compliance): Lines 201-1299
  * ISO 27001, NIST SSDF, OWASP SC Top 10, SCSVS, CCSS
  * SWC Registry, DASP Top 10, ConsenSys Best Practices
  * EU MiCA, DORA, DeFi Risk Assessment

- Layer 7 (Audit Readiness): Lines 850-954, 1391-1402, 1545-1563
  * Trail of Bits Audit Checklist (_audit_checklist_score)
  * Audit readiness assessment (_assess_audit_readiness)
  * Audit report generation (audit_assessment section)

Supported Standards:
- ISO/IEC 27001:2022 (Information Security) [Layer 6]
- NIST SSDF (Secure Software Development Framework) [Layer 6]
- OWASP SC Top 10 (Smart Contract Top 10) [Layer 6]
- OWASP SCSVS (Smart Contract Security Verification Standard) [Layer 6]
- CCSS v9.0 (CryptoCurrency Security Standard) [Layer 6]
- SWC Registry (Smart Contract Weakness Classification) [Layer 6]
- DASP Top 10 (Decentralized Application Security Project) [Layer 6]
- EEA DeFi Risk Assessment Guidelines [Layer 6]
- EU MiCA (Markets in Crypto-Assets Regulation) [Layer 6]
- DORA (Digital Operational Resilience Act) [Layer 6]
- Trail of Bits Audit Checklist [Layer 7 - Audit Readiness]
- ConsenSys Best Practices [Layer 6]

Publishes compliance reports and standards mapping to Context Bus.

    # LAYER 7: AUDIT READINESS
    # ========================================
    # The following methods implement Layer 7 (Audit Readiness) functionality
    # integrated within PolicyAgent for efficiency and data reuse.
    #
    # Design Decision: Layer 7 is intentionally NOT separated into a standalone
    # AuditAgent because:
    # 1. Audit checklist scoring requires access to all compliance data from Layer 6
    # 2. Trail of Bits checklist reuses vulnerability classifications from Layer 6
    # 3. Prevents duplication of compliance evidence and audit trail
    # 4. Maintains single source of truth for all regulatory reporting
    #
    # Layer 7 Methods:
    # - _audit_checklist_score() [lines 850-954]: Trail of Bits checklist
    # - _assess_audit_readiness() [lines 1545-1563]: Final audit readiness
    # - audit_assessment section in _generate_compliance_report() [lines 1391-1402]
