    Type Alias TraceEvent

    One observation emitted by a TracedOption combinator.

    spanId - Groups all events from one chain together. Stable across re-wraps.

    seq - Monotonic 0-based position within the span.

    op - Which combinator fired.

    tag - The container type name (e.g. "Option") from Symbol.toStringTag.

    inTag - Variant entering the op ("Some" | "None" for Option).

    outTag - Variant leaving the op; absent for terminal ops.

    label - Optional caller-supplied code-path name.

    meta - Op-specific detail (e.g. { kept: boolean } for filter).
