PRs that modify files under these paths cannot be approved by the agent — only a human can grant approval. Default is set in `harness/review.yaml` (`env.runner` and `env.sandbox`); an unset value is a misconfiguration (fail-closed). Set to an empty string to deliberately disable protected-path enforcement entirely. When set to a value that parses to no valid paths (e.g. stray or consecutive commas), the script aborts (fail-closed) as a likely misconfiguration. | See [`harness/review.yaml`](../harness/review.yaml) | Comma-separated path prefixes (e.g. `.github/,deploy/,manifests/`) |
 
 Override either variable by extending the harness file via a `base` reference and setting `env.runner` / `env.sandbox` in your custom harness YAML. `base` composition merges `env.runner`/`env.sandbox` per-key — child values override, everything else inherits from the base (ADR 0045, ADR 0055). Per ADR 0080 and ADR 0081, this harness-level override is the correct path; the CI workflow `env:` block is reserved for infrastructure plumbing, not agent behavior knobs like these.
