Enum StepKind 

#[non_exhaustive]
pub enum StepKind {
    LlmCall,
    ToolCall,
    SummaryCheckpoint,
    OpsEvent,
    MemoryRecall,
}

Discriminator for the kind of side effect a Step represents.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LlmCall

LLM completion or chat call.

ToolCall

Tool invocation through ToolInvoker.

SummaryCheckpoint

Summarizer checkpoint — distinct from a top-level LlmCall so summarizer overhead does not pollute substantive-reasoning cost and latency attribution.

OpsEvent

Operational-layer event emitted by klieo-ops (supervisor state changes, gate decisions, governor denials, etc.). The input field of the corresponding Step carries the raw serde_json::Value payload from Episode::Ops.

MemoryRecall

A graphRAG recall performed during the run (from Episode::MemoryRecall). Step::input carries { "query", "k" }; Step::output carries { "returned_fact_ids": [...] }.
