>
> Investigate whether short, successful spans can be filtered across Causeway,
> HTTP and JDBC instrumentation without orphaning useful descendants or losing
> failure context.
> - Compare JVM processor/exporter, Collector and backend/UI approaches.
> - Build an isolated proof-of-concept covering Boot-managed and
> Java-agent-managed tracing.
> - Verify ancestry preservation, error retention, asynchronous/remote
> descendants and late or incomplete traces.
> - Assess bounded buffering, failure handling, overhead and measurable
> span/byte savings.
> - Deliver reproducible evidence and a go, conditional-go or no-go
> recommendation, identifying prerequisites for any subsequent production
> implementation.
> Distinguish individual-span pruning from whole-trace sampling and UI-only
> collapsing.
> This investigation must not enable production filtering or introduce
> supported duration-threshold configuration.
