build-linux-verify could not compile PipeStatsTest: RoleDerivedJsonDumpPathForTesting is DISAGGREGATED-only and the verify flavour is deliberately monolith. The case name stays registered and GTEST_SKIPs there, matching the PIPE_PUSH pattern, so ctest -N still matches between flavours.
runtime_mode_proof.py logs opened MOBILEGL_LOG_FILE_PATH as a file. After the split that name is a base and the sink writes <base>.client.log / <base>.server.log, so the inproc proof died on FileNotFoundError after a green lane. It now reads through split_log_paths' role helpers and names the paths it looked for when none exist.
