This control plane turns raw BigQuery usage exports into one FinOps surface: bytes-scanned spikes, slot pressure, partition misses, reservation drift, attribution gaps, telemetry issues, and the remediation packets needed before forecast, chargeback, or optimization windows slip.
Contain the bytes-scanned spike, tune the partition misses, rebalance reservations, restore telemetry, and backfill labels before calling BigQuery query-cost posture healthy.
Every lane stays tied to owner, drift family, resource, scope, and the next concrete optimization move.
This is real query-cost and optimization proof, not generic cloud-cost copy.
