discrepancy suppression information

Once a METR Regulation Center has been alerted to a discrepancy, it may wish to suppress further notices in one of two ways. If it still wants vehicles to gather data but for that data not to be submitted except on request, it can use discrepancy suppression info flow to prevent METR Discrepancy Handling Centers from issuing consolidated discrepancy reports (but the newly gathered information is still available through the detailed flow). Alternatively, the METR Regulation Center can revise the associated rule meta-data to inform vehicles that a discrepancy with the rule is already known and that discrepancy reports should not be provided for the rule. This mechanism uses the centralized and localized rule distribution services. Furthermore, the METR Regulation Center may wish to inform other METR Discrepancy Handling Centers to correspondingly suppress further notices of those suppressed discrepancies.
