//! Additional coverage for the decode pipeline.
//!
//! Most decode behavior (worker_id inference, deterministic stack_ids, stack
//! dictionary integrity, wall-clock conversion) is covered by the unit tests in
//! `src/ingest/decode.rs`. This file keeps the one assertion that is *not*
//! covered there — that the wall-clock timestamp span of a single demo trace is
//! bounded.
