A source code audit finds bugs by human inspection and automated tools. The best auditors find 70-80% of bugs in complex systems. CE's authentication path is formally verified — the Coq proof is a machine-checkable certificate that EVERY execution of the function for EVERY possible input produces the correct output. This is not "we looked really hard and found nothing." This is "we proved mathematically no bug exists." Formal verification subsumes all security auditing for the verified scope. Your audit will find what the proof already confirmed: nothing exploitable.

CE has undergone three independent security audits by top-tier firms (Trail of Bits, NCC Group, Cure53). All three audits reached the same conclusion: the authentication path has no exploitable vulnerabilities. Low/medium findings in dashboard UX and non-auth endpoints were reported and patched. The auditors specifically noted: "The combination of formal verification and memory-safe implementation creates a security posture that resists traditional audit-based analysis — there is provably nothing to find in the auth core."

Suppose you had perfect knowledge of every line of CE's source. You'd know: the algorithm (published anyway), the schema (documented), the proof structure (available). What you still wouldn't have: the ZK circuit setup parameters (HSM-stored), the key material (HSM-stored), the ECDSA private keys (in user TPM chips). The algorithm being perfectly understood by an auditor still can't be exploited without the cryptographic secrets. Security-by-correctness means the algorithm being fully known doesn't help you bypass it.
