<pre />

Plugin-neutral optimization evidence with an open kind and optional custom payload.

## Fields

### `id: Option<String>`

Relay-assigned contribution identifier. Producer values are replaced on ingestion.

### `sequence: Option<u64>`

Relay-assigned order within the LLM call. Producer values are replaced on ingestion.

### `producer: String`

Stable producer or plugin identity.

### `kind: String`

Intentionally open to third-party optimization kinds.

### `applied: bool`

Whether the optimization affected the executed call.

### `model_transition: Option<LlmOptimizationModelTransition>`

Optional shared model transition.

### `token_impact: Option<LlmOptimizationTokenImpact>`

Optional shared token evidence.

### `payload_schema: Option<DataSchema>`

Schema of `payload`; required whenever `payload` is present.

### `payload: Option<JsonValue>`

Application-owned; when present payload_schema is required.

### `extra: HashMap<String, JsonValue>`

Unknown top-level fields from future producers.
