Security-Council threshold reduction (RT)
Circle USYC's assessment for RD-F-182 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
T-09 v1.1 candidate (not yet in v1 production shortlist); Cat 6B batch-24. Signal analogous to a Security Council threshold-reduction applies to USYC via the Entitlements/RolesAuthorityProxy permission system. No multisig exists to have its threshold reduced - admin is already an EOA (worst-case baseline). Most recent relevant upgrades: Ethereum USYC proxy last upgraded 2025-12-09; RolesAuthorityProxy last upgraded 2025-11-20. No recent permission-weakening events (both 5+ months ago). No new threshold-reduction, timelock-removal, or signer-addition event observed. Structural note: monitoring architecture must extend to cover RolesAuthority permission-change events directly for this protocol type, as there is no SC multisig to track threshold changes on.

Methodology #
Detect in real-time whether the bridge/protocol Security Council multisig executes a threshold reduction (e.g. 3/5 → 2/5), timelock removal, or new-signer addition within ≤14 days of either of those events.
