      "summary": "Reviewed a small Criterion benchmark that measures `tracing::span!` creation in `span_no_fields.rs`. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",

      "summary": "Reviewed `benches/span_repeated.rs`, a Criterion benchmark that repeatedly creates a `tracing::Span` in a tight loop for span-recording performance measurement. I checked for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths; none are present in this file.",

      "summary": "Reviewed `src/dispatcher.rs`, which is a thin documentation-and-reexport module for `tracing_core::dispatcher` APIs such as `set_default`, `with_default`, `set_global_default`, and `get_default`.

      "summary": "`src/instrument.rs` implements `tracing` future instrumentation: it wraps futures in `Instrumented` and `WithDispatch` helpers that enter a span or set a dispatcher when polled or dropped.
