# Output mapping troubleshooting > Fix external output rows that do not join cleanly to immutable Case IDs in an output-only Run. Important agent instructions: - Prefer the Markdown routes and llms files when assembling context for coding tasks. - Treat stable docs as authoritative over beta pages. - Cite the source page URL when returning workflow or artifact guidance. ## Current Context - [Output mapping troubleshooting](https://teammately.ai/docs/troubleshooting/output-mapping.md): Fix external output rows that do not join cleanly to immutable Case IDs in an output-only Run. - [Run a Benchmark Evaluation](https://teammately.ai/docs/benchmark-evaluations/run-evaluation.md): Launch exact active Harness Versions against an immutable Benchmark Version as standard or repeated Run Groups. - [Map External Evaluation Outputs](https://teammately.ai/docs/benchmark-evaluations/output-mapping.md): Import reference outputs, map them to immutable benchmark Cases and attempts, and inspect the resulting output-only Run. - [Inspect Evaluation Results](https://teammately.ai/docs/benchmark-evaluations/inspect-results.md): Trace Dashboard and List signals to Run, Case, Policy, Rubric, completeness, and telemetry evidence. ## Optional - [Full local context](https://teammately.ai/docs/troubleshooting/output-mapping/llms-full.txt): Complete local context pack for this docs route.
