## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Could not capture package-lock.json: source unavailable or larger than the capture limit. Open its source link to check setup.
> The intended package manager and version are not established by captured evidence.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.

- Full reference: get_artifact {"repo":"earendil-works/pi"}
- For a concrete task, call plan_repo_task with this repository, the task, and your actual checkout SHA when known. Compare returned analyzed_sha and evidence_gaps before relying on its file guidance.
- Follow the tool result's next_actions for more evidence. A missing result or unknown revision remains unverified.
