# hooks/inbox-boundary-check.sh — Stop hook that soft-nudges the agent to
# process pending inbox/ handoffs before yielding. Blocks the stop ONCE (emits
# a block decision + reason) when inbox-status reports pending items; on the
# harness re-entry (stop_hook_active: true) it steps aside so an unprocessable
# item or a mid-task pause never wedges. Self-skips where there's no inbox/ or
# no inbox-status. The real inbox-status is copied into the test project so the
# hook runs against real code, not a stub.
