+# Launch-only Alacritty adapter for SwarmForge (macOS).
+# Alacritty has no AppleScript dictionary and no reliable per-window id,
+# so this follows the same "launch-only" contract as windows-terminal.sh:
+#   - terminal_backend_can_open_sessions -> yes, we CAN open a surface
+#   - terminal_backend_tracks_windows    -> no, we can't track/reopen it
+#
+# That means SwarmForge will open one Alacritty window per role and skip
+# the watchdog (no auto-reopen if you close a window). Closing the first
+# configured window still does the normal cleanup/shutdown, because that
+# path doesn't depend on window tracking.
