+The merging extension — not the SDK — decides the final file name and may nest its output. The
+version of `Microsoft.Testing.Extensions.TrxReport` currently referenced by the SDK names its output
+`merged-<runId>.trx`, where `runId` is derived from the inputs, and writes it into a `merged/`
+subdirectory of the supplied output directory. Because the merged report is nested, a non-recursive
+`*.trx` glob over the results directory picks up the per-module inputs but not the merged report, so
+it does not double-count tests. CI that wants the merged report must target the `merged/` subdirectory
+explicitly, for example with `merged/merged-*.trx`; a broad recursive glob would also pick up the
+per-module inputs and double-count tests.
