Struct SessionUsageTracker 

pub struct SessionUsageTracker {
    pub cumulative: UsageReport,
    pub turn_count: u64,
    pub last_turn: Option<UsageReport>,
}

Accumulated usage tracking for an entire session.

The session loop maintains one of these and calls record_turn after each turn completes. The platform can read the cumulative usage at any time.

Fields

cumulative: UsageReport

Cumulative usage across all turns.

turn_count: u64

Number of turns completed.

last_turn: Option<UsageReport>

Usage from the most recent turn (for per-turn billing).
