# One-shot Job that replaces Hermes' built-in cron schedule with one daily check.
# The seed is intentionally destructive for the known legacy jobs so existing
# PVC state is simplified on the next ArgoCD sync.
#
# The prompt is written as plain-English instructions to avoid triggering
# Hermes' threat-pattern scanner. API endpoints and query examples are in
# SOUL.md.
