#!/usr/bin/env bash
# Phase 7 PTY + lifecycle smoke — remaining audit gaps.
#
# Assertions:
#   A. `wg spawn-task .coordinator-0` (Claude adapter) runs cleanly
#      under a PTY — proves the TUI's PTY pane won't crash when
#      the user focuses a Claude coordinator (TUI's dispatch goes
#      through spawn-task → exec into claude-handler).
#   B. Daemon service-stop → service-start cycle: Claude coordinator
#      reacquires its lock and processes new messages after the
#      round-trip (proves no state file corruption).
#   C. `wg tui-pty` hardcodes `wg nex` (native only) — this is a
#      documented Phase-3-era limitation, NOT a Phase 7 regression.
#      Record it here so the gap is visible.
