# ── Hermes Master Startup ─────────────────────────────────────────────
# Brings up the entire system after a reboot.
# Called by launchd (ai.hermes.startup) or manually.
#
# Boot order:
#   1. Gitea         (homebrew launchd — already handles itself)
#   2. Ollama        (macOS app — already handles itself via login item)
#   3. Hermes Gateway (launchd — already handles itself)
#   4. Webhook listener (port 7777)
#   5. Timmy-loop tmux session (4-pane dashboard)
#   6. Hermes cron engine (runs inside gateway)
#
# This script ensures 4 and 5 are alive. 1-3 and 6 are handled by
# their own launchd plists / login items.
# ───────────────────────────────────────────────────────────────────────
