Cost Savings via Infracost Estimates — Definition of Success

KPI: Cost Savings via Infracost Estimates Target: ≥ 25% on pilot estates (partial)

What this number means: the pre-apply cost estimate from Infracost shows the delta between the planned infrastructure and the current state. Negative deltas = savings.

How it's computed: sum(fact_cost_estimate.delta_usd WHERE delta < 0) per period.

What's grounded: the pre-apply estimate (Infracost reads plan JSON, offline).

What's deferred: actual-spend reconciliation from AWS CUR (D-096 — needs live AWS billing). The placeholder view placeholder_live_cur_reconciliation.csv has the schema ready.
