Breakage analysis per dependency
OpenEden's assessment for RD-F-052 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Breakage analysis: (1) TBillPriceOracle failure/staleness: vault reverts after 7 days; operator outage = protocol pause, not fund loss. (2) KYC Manager failure: all deposits/redemptions revert immediately. (3) Chainlink CCIP Router unavailability: USDO cross-chain transfers halt; local balances remain intact, no fund loss. (4) BNY Mellon off-chain failure: NAV attestation stops; oracle staleness after 7 days; vault operational pause. (5) Chainlink PoR stale: unknown impact (on-chain consumption not confirmed). Yellow: major dependencies documented with impact; no prior failure event for any dependency, but no formal mitigations published for extended BNY/operator outage.
