# FE-RB-001 — Boot configuration failure

Trigger on `BOOT_CONFIG_FAILURE` after the single bounded refetch fails. Stop
product route mounting and show the safe support shell; the planned owner
triage target is five minutes. Escalate from the environment/config owner to
the release owner.

Close only after a clean-session boot mounts the product root, config
validation evidence passes, and repeated boot-error telemetry is absent.
