Owner, curator and guardian keys, and how much money each one stands behind. Read from the chain rather than from documentation — which is why custodians, issuers and bridges are not on this page yet.
An owner key is not a governance nicety. It can do in one transaction what a bad strategy takes months to do. So this ranks by dollars behind a key rather than by vaults per key: nine vaults holding a billion and nineteen holding half of that are different findings, and counting rows would order them the wrong way round.
Access control is read from the chain and stored only where the venue exposes it. The covered vaults are the large ones, so coverage is thin by count and broad by capital.
A guardian is the party that can stop a timelocked change before it lands. Where there is none, the owner is the whole of the control.
Owner reads as the zero address, which means ownership was given up. Nobody can change these vaults — which removes the key risk and removes the ability to fix a fault. It is not a failed read; that is reported as unknown.
What we read at all, and what nobody can: the perimeter.
