### [THREAT_MODEL]
adversaries:
  - type: "APT"
    mitigations:
      - "Capability-based auth → No lateral movement."
      - "Idris2 dependent type proofs → No exploit primitives in verified core."
      - "ECHIDNA proof verification in CI → Immediate detection of proof regression."
      - "Transparency logs → Immediate detection of supply chain tampering."
  - type: "Supply Chain Attack"
    mitigations:
      - "All computation in Idris2 → Bindings cannot reimplement logic."
      - "Architecture enforcement workflow → Blocks unsafe reimplementations."
      - "Hypatia neurosymbolic scan → Detects unsafe patterns in bindings."
      - "SHA-pinned GitHub Actions → No action injection."
  - type: "Ransomware"
    mitigations:
      - "Consent-Aware HTTP → No bulk exfiltration."
      - "SDP (CAdRE Router) → Resource isolation."
      - "Immutable logs → Instant rollback."
  - type: "Quantum Adversary"
    mitigations:
      - "Kyber1024 + Dilithium5 → PQ-resistant crypto."
      - "SPHINCS+ fallback → Crypto agility."
      - "GitBot-Fleet → Automated key rotation."
