# scripts/manage_sidecar.sh — ops helper for the BizPortal Python sidecar.
#
# Auto-loaded at login via com.ysterbaard.bizportal-sidecar.plist.
#
# Subcommands:
#   status   — print whether the sidecar is running and the /health JSON.
#   start    — load + boot the LaunchAgent (safe to re-run when already up).
#   stop     — kickstart -k to terminate; the agent will NOT be reloaded.
#   restart  — kickstart -k to terminate + re-launch.
#   logs     — tail the stdout/stderr logs.
#   doctor   — show what's wired up: plist path, working dir, /health,
#              who owns the port, and whether the Next.js sidecar URL env
#              is set.
#
# Used by:
#   - launchd (auto-start at login)
#   - humans debugging "bizportal search is stuck again"
#   - cron smoke checks
