Tweaks to the artifacts for ECS runner

 For `PROVISIONAL` and `SYSTEM` scoring, the runner writes progress to the phase review summation metadata through `POST /v6/marathon-match/internal/scoring-progress`. Review API exposes this as `reviewSummation.metadata.testProcess` (`provisional` or `system`), `reviewSummation.metadata.testProgress` (`0` to `1`), and `reviewSummation.metadata.testStatus` (`IN PROGRESS`, `SUCCESS`, or `FAILED`) when metadata is included in the response. In-progress summations keep a neutral placeholder score and must be rendered as unavailable based on `testStatus`; only `FAILED` progress uses the failed-score sentinel. SYSTEM timeout failures also include `reviewSummation.metadata.timed_out = true`.
 
+For generic runner artifacts, the public provisional/system `output.txt` includes testcase ordinal, runtime, runner/tester errors, and submitted-solution stderr, but excludes submitted-solution stdout and raw per-test scores. Per-test score details remain in the private internal `reviews.json` artifact and callback metadata.
+
 When more than one phase config matches the currently open challenge phases, the handler launches one scorer task per match. This is the supported way to run both `EXAMPLE` and `PROVISIONAL` scoring from the same Submission phase.

 The runner rejects output once generated public `output.txt` content or a public/private artifact archive would exceed `MM_RUNNER_MAX_OUTPUT_BYTES`. The default is `10000000` bytes. The trusted parent runner passes the resolved limit into the isolated tester child, so generated generic-runner output and uploaded artifact zips use the same cap.
 
+Generic runner public `output.txt` entries show testcase ordinal, runtime, runner/tester errors, and submitted-solution stderr. They intentionally omit submitted-solution stdout and raw per-test scores. The private internal artifact (`reviews.json` in the `*-internal` zip) carries the per-test `testScores` used for diagnostics and score verification.
