Read-only production debugging for the Companions runtime on Railway and box.ascii.dev. Use when production box launches fail, a chat dies or stalls while waiting for input, turns sit queued or interrupted, a Companion appears to reply forever, /healthz is unhealthy, or an operator needs Railway deployment status, redacted runtime logs, provider Box inventory, or named read-only PostgreSQL runtime queries. Every script redacts credentials; the only mutation is a double-gated service restart.
