# Stop Spinifex development environment

# Note: Services are stopped using PID files, so data-dir is not required

# Accept optional data directory argument
DATA_DIR="${1:-$HOME/spinifex}"

# Always use the logs directory for PID files — start-dev.sh writes shell PIDs
# there, and Go services write PIDs to their own data dirs. This ensures
# consistent stop behavior for both single-node and multi-node setups.
