# PAILot iOS Deploy Script
#
# Installs a personal (Pro-unlocked) PAILot build onto one or more iOS devices.
#
# ── Two transports ─────────────────────────────────────────────────────────
# 1. devicectl (default): `xcrun devicectl device install`. Reaches the device
#    over Apple's CoreDevice tunnel, but DISCOVERY is mDNS/Bonjour — so it only
#    works when the Mac and device share the local network (USB or same wifi).
#    It does NOT traverse Tailscale: a device on a remote network shows
#    "unavailable" and both its .ts.net name and tailnet IP are rejected.
#
# 2. --ota (fully remote): build + publish the IPA to the aibroker-ota hub, which
#    serves it over Tailscale (HTTPS via Tailscale Serve). Open the returned URL
#    in Safari on ANY device on the tailnet and tap Install. This is the path to
#    use when you are NOT on the local wifi. Requires `aibroker ota up` once.
#    (The device UDID must still be in the provisioning profile.)
#
# ── Usage ──────────────────────────────────────────────────────────────────
#   bash tools/deploy.sh              # Matthias' iPhone (default, local network)
#   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 id (local network)
#   bash tools/deploy.sh --ota        # remote install over Tailscale (prints URL)
#   bash tools/deploy.sh --build      # force a fresh Pro-unlocked build first
#   bash tools/deploy.sh --check      # list devices devicectl can currently reach
