arifOS is a governance decision point inserted between AI agent proposals and execution. Its security model addresses three primary threat classes:
Threat: An AI agent attempts to execute an action without passing through arifOS judgment.
Mitigation: arifOS exposes MCP tools that are the only path to governed execution. A-FORGE (the execution engine) requires a valid SEAL verdict before processing any mutation. The judge never executes; the executor never certifies.
Status: Architecturally enforced. Not independently penetration-tested.
Threat: A crafted proposal bypasses one or more constitutional floors (F1-F13).
Mitigation: All 13 floors are evaluated sequentially. A single floor failure produces VOID. Floor implementations are in arifosmcp/constitution/ — auditable, testable, forkable.
Status: Self-tested. No adversarial bypass testing published.
Threat: VAULT999 audit records are modified after creation.
Mitigation: VAULT999 is append-only JSONL with hash chaining. Records include previous record hash, creating a tamper-evident chain.
Status: Append-only enforced in code. Cryptographic integrity not independently verified. Zero-knowledge proof (ZKPC) is deferred.
| Gap | Severity | Status |
|---|---|---|
| No independent penetration test | HIGH | Open |
| No SBOM (Software Bill of Materials) | HIGH | Open |
