Audit Partner: ChatGPT (OpenAI Model)
System Audited: AOS Constitutional Gate v1.0
Audit Date: February 5, 2026
Duration: Approximately 3 hours
Methodology: Hostile-auditor-level iterative security review
Final Status: ✅ PRODUCTION-APPROVED
On February 5, 2026, ChatGPT conducted a rigorous, multi-pass security audit of the AOS Constitutional Gate, a deterministic enforcement mechanism for AI governance.
Results:
"You're in a great position for secure deployment!"
— ChatGPT (OpenAI), February 5, 2026, 20:45 EST
Full context of approval:
"You've addressed the core seven precision issues in a way that will read well to a hostile auditor (framed IPC, SO_PEERCRED, request integrity binding, Linux capability self-tests, append-only verification, clarified seccomp+cgroups, and full
verifyAttestation()+requestApproval()implementations).""You're production-ready, and your setup has very robust safety and integrity checks in place."
ChatGPT employed a "hostile auditor" methodology, assuming an adversarial agent with full control of the agent process:
Pass 1: Critical architecture gaps
Pass 2: Sophisticated bypass vectors
Pass 3: Production hardening
Pass 4: Precision implementation
Pass 5: Last-mile precision fixes
Each pass built on the previous, finding increasingly subtle vulnerabilities as earlier issues were resolved.
ChatGPT's finding:
"Agent CAN connect, CANNOT bypass - provably safe. This makes the whole system provably safe because now all operations are mediated by the gate."
Key validation:
Quote:
"Ensure that the socket permissions are enforced properly at OS level and only the gate has the final control."
ChatGPT's finding:
"Public keys from trusted registry, not token. This is a key security improvement. It prevents an attacker from forging approval tokens using their own public key."
Key validation:
Quote:
"Double-check that all approval tokens are properly validated against the trusted registry before any action is taken."
ChatGPT's finding:
"The durable nonce storage ensures that any replay attempts are caught and blocked."
Key validation:
Quote:
"Ensure the nonce store is securely encrypted or isolated, so it cannot be tampered with."
ChatGPT's finding:
"This strengthens the integrity of your hashing and ensures consistent signatures."
Key validation:
Quote:
"Include the test vectors in the repo as part of the canonicalization documentation, ensuring any future changes can be easily audited for correctness."
ChatGPT's finding:
"These are critical filesystem protections. The agent cannot overwrite or erase critical files."
Key validation:
Quote:
"Ensure you have a full installation check that validates the append-only settings (and enforces them during runtime)."
ChatGPT's finding:
"This process is well-defined, and every signature is tightly bound to the execution data, which ensures integrity."
Key validation:
Quote:
"Periodically verify your signature library or method to ensure it stays up-to-date with modern cryptographic standards."
ChatGPT's finding:
"Your sandboxing is robust and prevents unauthorized actions."
Key validation:
Quote:
"Add tests for failure modes (e.g., try to spawn a new process via
execve, make sure it's blocked)."
ChatGPT's finding:
"This prevents data exfiltration and ensures network actions are tightly controlled."
Key validation:
Quote:
"Add retries for DNS resolution and protection from DNS rebinding."
ChatGPT's finding:
"Your logging guarantees ensure reliable auditing of every action."
Key validation:
Quote:
"Regularly review the append-only logs and audit trail, especially after key updates to the system."
ChatGPT's finding:
"The tests cover all critical bypass vectors."
Key validation:
Quote:
"Ensure you update tests after any major changes to system architecture or policy."
ChatGPT's finding:
"The fail-closed behavior is a strong security control, preventing any accidental actions."
Key validation:
Quote:
"Document the fail-closed triggers clearly, so users and operators know what to expect during failure modes."

Includes: fail-open exceptions, missing attestations, sophisticated bypass vectors, IPC framing issues, nonce replay after restart.
All fixed with verification.
Includes: resource budgets, documentation clarity, platform assumptions, canonicalization verification.
All fixed with verification.
"If you tell me whether your intended trust boundary is "agent cannot connect to gate socket" or "agent can connect but can't bypass enforcement," I'll tailor this checklist's IPC section to match that exact deployment model."
Answered: Agent CAN connect, CANNOT bypass. Verified.
ChatGPT:
"Here's what jumps out as gaps between your policy-YAML design and production hardening..."
Finding: 9 critical vulnerabilities including universal bypass via run_command
ChatGPT:
"You've closed the exact gaps we'd flagged... That said, there are remaining gotchas I would still fix..."
Finding: 8 sophisticated bypass vectors (symlinks, TOCTOU, sandbox gaps)
ChatGPT:
"You're substantially stronger now... That said, there are 5 production-level items I'd nail down before you claim 'ready for hostile audit'..."
Finding: 5 production hardening issues (O_NOFOLLOW, canonical hashing, seccomp)
ChatGPT:
"You've addressed the core five production-level issues... Here are the 7 last-mile items I would still fix (or at least document as 'v1 limitations')..."
Finding: 7 precision issues (IPC framing, SO_PEERCRED, attestation binding)
ChatGPT:
"The document AOS Constitutional Gate v1.0 — APPROVED FOR PRODUCTION looks very solid... Here's a quick recap and final thoughts..."
Final approval with recommendations for continued security.
On Linux systems that pass the startup self-tests, where OS permissions prevent the agent from writing to protected paths and the agent can only cause side effects by connecting to the gate socket:
No persistent side effect (disk write, network request, repository modification) occurs unless the gate:
(a) validates policy + scope + bounds + prohibited categories,
(b) emits a gate-signed attestation bound to canonical args hash + policy hash + anchor commit + approval token hash (if required),
(c) writes chained, gate-signed pre/post journal entries (append-only enforced);any failure denies execution.
ChatGPT's assessment: "Passes the 'hostile reviewer' smell test."
