Root Operational Bottleneck
SaaS cost-takeout initiatives are tracked in a sheet next to an unused-seat export, so savings are reported when the initiative is marked done, not when seats are reclaimed.
Control Hazard & Audit Exposure
Takeout savings are reported from a tracker that never reclaimed the unused licenses, and the seat count the vendor bills does not change.

Seat-Takeout Engine that Records Savings Only After Unused Licenses Are Reclaimed
Seat-takeout engine that records savings only after unused licenses are deprovisioned and the vendor quantity equals the reclaimed count.
Continuous Assertion Rule
Takeout assertion: a cost-takeout saving cannot post unless unused licenses for that SKU are deprovisioned and the vendor quantity matches.
