Existing TiVo CableCARD lost pairing after outage - need factory-team re-pairing

My existing Motorola/Arris CableCARD has worked in this TiVo Roamio for years. It stopped working during an Xfinity outage and has not recovered.

TiVo diagnostics show good RF signal and Signal Lock, VCTID is populated, OOB messages are incrementing, and Conditional Access shows Con: Yes, but Val: ?, indicating the card is no longer paired/validated.

Phone and chat support have been unable to resolve it. One rep discovered that Xfinity had a different Data ID stored than the TiVo currently displays. I provided the current Data ID, but Val remains ?.

The Xfinity CableCARD activation website also fails at account authentication and directs me back to the CableCARD support number.

This is an existing active CableCARD, not a request for a new card. Can this please be escalated to the team/factory team that can update the Host ID/Data ID pairing and send the validation signal?
