Enum QuotaCheckError 

pub enum QuotaCheckError {
    Quota(QuotaError),
    Sql(Error),
}

Wire-shape error for check_quota — separates the “the agent hit the limit” case from “the substrate read failed” so callers can surface the former as a QUOTA_EXCEEDED diagnostic and the latter as a 500-class internal error.

Variants

Quota(QuotaError)

The pending op would exceed one of the three limits.

Sql(Error)

The substrate read failed (DB error, missing migration, etc.).
