Root Operational Bottleneck
Cardholder lists are updated from an HR status-change export, so cancellations wait on someone comparing the active-card file to terminations.
Control Hazard & Audit Exposure
Departed employees keep charging on corporate cards for weeks because the issuer file was not cut when HRIS status changed.

HRIS Deprovisioning Hook & Automated Card Cancellation Service
HRIS termination webhook that cancels issuer cards and blocks authorizations the moment employment status is inactive.
Continuous Assertion Rule
Deprovision assertion: an employment termination must cancel every card assigned to that worker before the next authorization window, or the card is frozen and queued.
