    Interface TraceRetention

    What the trace ring buffer holds and what it has discarded.

    Returned with every listing so an empty result is readable: a filter that matched nothing and a match that aged out are otherwise identical.

    interface TraceRetention {
        evicted: number;
        max_traces: number;
        oldest_seq: number | null;
        retained: number;
        truncated: boolean;
    }
    Index
    evicted: number
    max_traces: number
    oldest_seq: number | null

    seq of the oldest trace still held; anything older is gone.

    retained: number
    truncated: boolean
