Missing Outputs
Use this when an Evaluation Run has no response for an intended Case. First identify whether the evidence came from managed Harness execution or an imported output-only Run.
Symptom
A managed Run is incomplete or has a failed or unevaluable Case attempt, or an imported output-only Run shows an unmatched Case row. An input-only Case by itself is not an error: managed execution is expected to generate its response.
Likely causes
- Managed execution failed, stopped, or could not evaluate the Case.
- The wrong saved Harness Version or execution settings were selected.
- An external output row has a missing, unknown, or duplicate immutable Case ID.
- The imported file omitted Cases that the output-only Run was intended to cover.
Diagnostic checks
- Open the Run and check its lifecycle, attempts, failed Cases, and selected Harness Version.
- Confirm that the Case belongs to the immutable Benchmark Version used by the Run.
- For imported outputs, compare external identifiers with the immutable Case IDs shown by the mapping surface.
- Confirm that the intended output column and candidate metadata were selected before import.
Fix
- For managed execution, correct the Harness or execution problem and start a new Run against the same Benchmark Version when that boundary is still intended.
- For imported outputs, correct the external rows and repeat mapping with immutable Case IDs.
- Keep managed and imported-output diagnoses separate; an imported response does not become a saved Harness Version.
- Change the current Dataset and create a new Snapshot only when Case membership itself is wrong—not merely because a Run response is missing.
Prevention
- Save the exact Harness Version before managed execution and review execution settings.
- Export or preserve immutable Case IDs through external generation.
- Validate several mapped rows before creating an output-only Run.
- Use Run Metadata to identify the candidate or external output set without pretending it is a Harness Version.

Source confidence
Code-backed: the Run modal and Run detail establish managed execution identity and status; the output-mapping modal and List surface establish imported output-only Runs and unmatched Case handling. Input-only Cases are valid inputs to managed execution.
