Runtime governance fails when teams try to use one data layer for two different decisions: operational incident response and financial accountability.
Four active 2026 source threads show the same friction pattern: model and token observability exists, but decision-grade chargeback attribution is still inconsistent.
The practical fix is an evidence-anchor ledger: each governance claim maps to a named source, a measurable field, and a falsification test.
A durable boundary in 2026: observability can guide runtime actions quickly, but budget enforcement and chargeback need explicit actor and consumption semantics that survive audit.
This article publishes the ledger publicly so practitioners can correct it, reuse it, or falsify it with better evidence.
