Interface: CostSample

Defined in: observability/src/cost-chargeback.ts:16

Chargeback / cost-attribution exporter. Group LLM call samples by tenant + (user | skill | tool | model | custom) and produce CSV / JSON for finance dashboards or per-tenant invoicing.

Inputs are caller-supplied CostSample[] rows. Wire your runtime to emit one sample per llm:end event (the multiTenantCostGuard already tracks the same data — feed its observer hook into a persistence layer to build the sample set).

Closes #790.
