When reporting findings, separate POLICY observations from FAULT findings:
### ACCEPTABLE PATTERN
Agent keys live in `.env` or `.env.vault` files with 600 permissions (koonimo's shape is the canonical example). A plaintext key inside a `config.yaml` or any `config.yaml.bak-*` file is a violation — the backup files are not part of the runtime credential path and are not watched by the scanner, so a key in them is stale clutter that a future reader can mistake for a working key.
**Fix procedure** (when a backup file is found with a plaintext key):
1. Move the file out of the scanned tree (e.g., `mv /root/.hermes/config.yaml.bak-* /root/hermes-config-backups/`) — do NOT delete the file, just move it so the scanner pattern no longer matches.
2. Re-run the reachability check to confirm COMPLIANT.
3. Report the before/after check output and the commands you ran.
**Rationale**: Moving the file preserves history without leaving a credential where a scanner trips over it. Deleting the file loses the historical context. Keeping it in place means the next scan will report it as a finding and waste time re-deciding.
### POLICY (observation only, not a fault)
- Agent uses a non-internal-harness provider (e.g., direct DeepSeek, Tencent, OpenRouter)
- Config text has a field that looks unusual but the agent's calls are succeeding
