Struct SessionTraceStep 

pub struct SessionTraceStep {
    pub trace_id: String,
    pub origin_function: String,
    pub status: String,
    pub memory_query: String,
    pub memory_context: String,
    pub method_params: Value,
    pub method_return_value: Option<Value>,
    pub error_message: String,
    pub session_feedback: String,
}

One agent-trace step persisted in a session — mirrors Python’s SessionAgentTraceEntry (no created_at; ordering is positional).

Library-internal type; kept snake_case to match Python’s persisted JSON shape so cross-SDK reads stay byte-equal. This is not an HTTP DTO — the wire-side camelCase rule (Decision 10) does not apply here.

Fields

trace_id: String

Server-generated UUID4 — returned by SessionManager::add_agent_trace_step.

origin_function: String

status: String

Free-form per Python validator; typically "success" / "error".

memory_query: String

memory_context: String

method_params: Value

Default {} — matches Python’s default_factory=dict.

method_return_value: Option<Value>

error_message: String

session_feedback: String

LLM-resolved feedback string — generation owned by SessionManager (LIB-01); callers in this task pass "" until LIB-01 lands.
