Struct TrajectoryStepRecord 

pub struct TrajectoryStepRecord {
    pub tool_name: String,
    pub tool_args: Value,
    pub output_summary: String,
    pub duration_ms: u64,
    pub is_error: bool,
    pub tool_call_id: String,
    pub timestamp: DateTime<Utc>,
}

A single tool execution step recorded in a session (RFC-015).

Persisted alongside the agent response so that the Web UI can render the execution timeline (tool calls, durations, errors) when the user re-opens the session later. Mirrors memory::sona::TrajectoryStep but is duplicated here to avoid a kernel-state → memory dependency cycle.

Fields

tool_name: String

Name of the tool that was called.

tool_args: Value

Tool input arguments (JSON).

output_summary: String

Truncated output (max ~500 chars).

duration_ms: u64

Wall-clock duration in milliseconds.

is_error: bool

Whether the tool returned an error.

tool_call_id: String

Provider-specific tool call ID (for start/end correlation).

timestamp: DateTime<Utc>

Timestamp when the step started.
