Breakage analysis per dependency

Compound V3 (Comet)'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 #

Stale positive price silently accepted (highest-impact failure). Zero price causes market halt (recoverable). Breakage analysis documented per dependency.

Detail #

Key finding: stale-but-positive price from Chainlink is accepted unconditionally with no staleness check. This can cause systematic mis-pricing of collateral leading to incorrect liquidation thresholds and bad debt risk. Zero price causes BadPrice() revert halting markets, which is recoverable via governance.
