A correctly run ceremony for an unsound setup protocol

Every operational control works — diverse participants, verified contributions, published transcript, beacon — and the parameters are still unsound, because the setup protocol published an element it should not have. This has happened: a flaw in an early pairing-based construction's parameter generation allowed unlimited undetectable counterfeiting and went unnoticed for years. No amount of ceremony hygiene addresses it.

Mitigation

Have the setup construction itself reviewed as cryptography, separately from the ceremony's operation — see §03. Prefer constructions with multiple independent implementations and published security proofs over bespoke or modified parameter generation.
