# End-to-end repro of #1718 against YOUR bb dev instance.
#
# Usage: BB_REPO=/abs/bb/worktree ./1718-repro.sh <project id> [idle|active]
#   idle   (default) Claude backgrounds `sleep 120`, replies "started", thread
#                    goes idle -> `bb thread stop` (release) -> new message.
#   active           Claude backgrounds `sleep 120` and keeps polling it, so the
#                    turn is still running -> `bb thread stop` (interrupt) -> new message.
#
# Needs: sqlite3 not required; jq, curl. Uses ./1718-bb.sh and ./1718-events.sh
# next to this script. Real claude-code usage (two tiny turns).
