# ============================= Sunday Morning Coffee Report ===================================
# ==============================================================================================
# Weekly monitoring orchestrator — runs all Sunday monitor scripts in sequence.
# Designed to be read over coffee Sunday morning while the system is fully caught up
# from the 2:30am maintenance window.
# Schedule: 0 7 * * 0 (7am Sunday — after weekly_sync_maintenance.sh finishes at ~3am)
#
# ── SCRIPTS (master.conf COFFEE_REPORT_SCRIPTS) ───────────────────────────────────────────────
#   Each script runs independently, logs to its own output, and notifies on findings.
#   All scripts receive --dry-run and --log flags from this orchestrator when set.
#
# ── HOST AWARENESS ────────────────────────────────────────────────────────────────────────────
#   detect_hosts() sets MY_ID — used in banner and summary.
#   HOST1 primary: runs all scripts. HOST2: limited to host-aware scripts only.
#
# ── USAGE ─────────────────────────────────────────────────────────────────────────────────────
#   sunday_morning_coffee_report.sh              — normal run
#   sunday_morning_coffee_report.sh --dry-run    — preview without any writes or notifications
#   sunday_morning_coffee_report.sh --log        — verbose per-script output
#   sunday_morning_coffee_report.sh --status     — show configured scripts and exit
