#!/usr/bin/env bash
# restore-minikanren.sh — print recovery state for the miniKanren-on-SX loop.
#
# The loop runs as a Claude Code instance inside a tmux session named `minikanren`,
# operating in a git worktree at /root/rose-ash-loops/minikanren on branch
# loops/minikanren. This script shows you where things stand. To respawn, see the
# bottom of the output.
#
# Usage:
#   bash plans/restore-minikanren.sh           # status snapshot
#   bash plans/restore-minikanren.sh --print   # also cat the briefing
#

  fresh every iteration and picks up wherever the queue left off.
