When shell commands inside the gateway get blocked with "Gateway would kill this command before it could complete", the guard heuristically flags the path. Even read-only scripts like `check_backlinks.sh` and `check_knowledge_index.sh` get blocked from subagent terminals.

Fallback order for knowledge / broken-link checks:

1. `~/.hermes/cron/output/check-backlinks-last.txt` — canonical nightly cron artifact. Format: `[ts] rc=N scanned_md=N total_links=N unique_targets=N broken=N`
2. `operations/audit/backlinks-report-YYYY-MM-DD.md` — full §1/§2/§3 v3 backlink bus section
3. `operations/logs/YYYY-MM-DD.md` — grep "check_backlinks\|broken_count" for narrative

Reporting: do NOT fabricate stdout. Cite the cache file + values used.
