Circuit breaker on price deviation
M^0'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 #
MinterRateModel enforces a hard cap of 40,000 bps (400%) on the minter rate — functions as a maximum-rate guard but is not a price-deviation circuit breaker. TTG governance can replace the rate model if problematic but 15-day epoch cycle creates bounded delay. No staleness-based circuit breaker applicable to governance-parameterized model.

Methodology #
Determine whether the protocol halts or reverts if the oracle-reported price deviates by more than X% from a reference within Y blocks.
