+## Outcome
+
+- Added `scripts/run-rcon-data-pipeline-tests.ps1`.
+- The script compiles backend modules, runs RCON parser/storage/materialization/link checks without real RCON credentials, and performs an optional backend health smoke check only when Docker Compose already has `backend` running.
+- The script prefers `pytest` when available and falls back to deterministic offline checks plus unittest suites when `pytest` is absent.
+- Validation: `powershell -ExecutionPolicy Bypass -File scripts/run-rcon-data-pipeline-tests.ps1` passed.
+- Validation: `powershell -ExecutionPolicy Bypass -File scripts/run-integration-tests.ps1` returned exit code 0, but its nested historical UI regression check emitted an existing frontend assertion about the missing recent-match external action label. No frontend files were changed in this platform task.
+- Real RCON checks were skipped by design because the script must run without RCON credentials.
