Signer composition and verifiability of the mint authority

A nominal mint-multisig threshold carries information only if signer independence and role assignment can be confirmed by an outside observer. Opaque role management around the minter set turns offboarding failures and unrevoked access into persistent issuance-attack vectors.

Tier	Reasoning	Evidence
Unclear	A nominal mint threshold cannot be relied upon without verified signer independence. Opaque role management turns offboarding failures and unrevoked minter access into persistent attack vectors.	Ronin's 5-of-9 was functionally controlled by Sky Mavis ($625M loss); Orbit Chain's 7-of-10 was defeated by a former CISO relaxing firewalls ($81.5M loss); Multichain's self-described MPC was administered by a single principal ($126M loss).
Clear	Clear documentation with named minter roles, on-chain verifiable access control, published multisig addresses, and verifiable signer composition allows an external observer to assess the actual concentration of issuance control.	MakerDAO governance multisigs, the Lido validator set, and Aave Stewards publish named roles and on-chain-verifiable access control.
