Circuit breaker on price deviation

Pendle Finance's assessment for RD-F-057 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

No price-deviation circuit breaker in the Pendle oracle contract. Contract reverts on TwapDurationTooLarge (cardinality limit) but has no price-movement halt. Chaos Labs external PT Risk Oracle for Aave has a liquidity killswitch (LP concentration at 96%) but this is external to Pendle core. Manual pause via dev multisig is the only Pendle-side emergency mechanism.
