<pre />

Close-time accounting attached to the normalized LLM response.

## Fields

Wire schema version.

### `calculation_version: String`

Arithmetic implementation version.

### `status: LlmOptimizationSummaryStatus`

Whether all accounting inputs were available.

### `limitations: Vec<String>`

Machine-readable reasons for partial accounting.

### `baseline_model: Option<LlmOptimizationModel>`

Counterfactual model used for baseline pricing.

### `effective_model: Option<LlmOptimizationModel>`

Model that actually served the terminal response.

### `effective_usage: Option<Usage>`

Usage observed on the effective response.

### `baseline_usage: Option<Usage>`

Counterfactual usage derived from observed usage plus explicit savings.

### `tokens_saved: LlmOptimizationTokens`

Explicit aggregate token reductions, retained independently from pricing.

### `baseline_cost: Option<CostEstimate>`

Estimated cost for baseline model/usage.

### `actual_cost: Option<CostEstimate>`

Provider-reported or Relay-estimated actual cost.

### `estimated_cost_saved: Option<f64>`

Baseline cost minus actual cost when both share a currency.

### `currency: Option<String>`

Currency for `estimated_cost_saved`.

### `contributions: Vec<LlmOptimizationContribution>`

Ordered, bounded source evidence used by the calculation.
