# ========================= Monthly Maintenance Orchestrator ===================================
# ==============================================================================================
# Uptime-triggered monthly maintenance — runs heavy tasks that need a stable, settled system.
# Fires only when BOTH gates pass:
# 1. Server uptime >= MONTHLY_UPTIME_THRESHOLD_DAYS days
# 2. Last run was >= MONTHLY_RUN_INTERVAL_DAYS days ago (or never run)
#
# ── WHY UPTIME-GATED ─────────────────────────────────────────────────────────────────────────
# A scheduled reboot resets uptime. Monthly tasks (ZFS scrub, SMART long test) need a
# stable, settled system — not one that just rebooted. Uptime-gating ensures maintenance
# only runs after the server has been healthy for a full month, never immediately post-boot.
# If uptime or interval gate is not met on the 15th, the run is skipped until next month.
#
# ── HOW TO CALL ──────────────────────────────────────────────────────────────────────────────
# Schedule: 0 0 15 * * (15th of each month at midnight)
# Silent exit 0 when either gate is not met. Only outputs when maintenance actually fires.
#
# ── STATE FILE ────────────────────────────────────────────────────────────────────────────────
# MONTHLY_LAST_RUN_FILE — /boot/config — survives reboots, available before array starts.
# Written after each run (pass or partial fail). Format: Unix timestamp.
# A reboot does NOT reset the last-run state — the interval gate survives independently
# of the uptime gate. Both must pass before maintenance fires again.
#
# ── CONFIGURATION (master.conf) ───────────────────────────────────────────────────────────────
# MONTHLY_MAINTENANCE_SCRIPTS — ordered list of scripts to run
# MONTHLY_UPTIME_THRESHOLD_DAYS — minimum uptime in days before maintenance fires
# MONTHLY_RUN_INTERVAL_DAYS — minimum days since last run before running again
# MONTHLY_LAST_RUN_FILE — state file path — /boot/config, survives reboots
#
# ── USAGE ─────────────────────────────────────────────────────────────────────────────────────
# monthly_maintenance.sh — normal run (uptime + interval gates enforced)
# monthly_maintenance.sh --dry-run — preview gate state and scripts without running
# monthly_maintenance.sh --status — show gate state, last run, and configured scripts
# monthly_maintenance.sh --force — bypass uptime + interval gates (manual override)
# monthly_maintenance.sh --log — verbose output
