# PAILot iOS Deploy Script
#
# Installs a personal (Pro-unlocked) PAILot build onto one or more iOS devices.
#
# ── Remote / "fully remote" targets ────────────────────────────────────────
# Installation uses `xcrun devicectl device install`, which reaches the device
# over Apple's CoreDevice tunnel — USB, local network, OR any routable network
# path where the device is paired (e.g. across Tailscale). There is NO special
# remote logic to add: once a device has been paired, `--device <id>` works
# whether it sits on your desk or across the world, as long as it is awake and
# reachable. That is exactly how the iPad here installs — it is a `localNetwork`
# device, never plugged in. (First-time discovery of a NEW device uses .local /
# mDNS, which does not cross networks, so a device must be paired at least once
# on the local network before it can be driven fully remotely.)
# Check reachability any time with:  bash tools/deploy.sh --check
#
# ── Usage ──────────────────────────────────────────────────────────────────
#   bash tools/deploy.sh              # Matthias' iPhone (default)
#   bash tools/deploy.sh -a           # Amelie's iPhone
#   bash tools/deploy.sh -i           # Matthias' iPad
#   bash tools/deploy.sh --all        # every known device (continues on failure)
#   bash tools/deploy.sh --device ID  # explicit CoreDevice identifier (any remote device)
#   bash tools/deploy.sh --build      # force a fresh Pro-unlocked build first
#   bash tools/deploy.sh --check      # list devices devicectl can currently reach
