// Package pipeline_test provides an out-of-process distributed integration test
// for the trace in-merge filter via the .so sampler plugin on two external data
// nodes with one external liaison. The suite is gated behind the `trace_pipeline`
// build tag and runs only via `make test-trace-pipeline` (it needs a CGO server +
// .so and is excluded from -race). This untagged file keeps the package
// compilable for the generic CI sweep, where it has no test files and is skipped.
