# smoke-test.sh — sanity checks for the pi-devbox image
#
# Usage: ./scripts/smoke-test.sh <image>
#
# Verifies:
#   - pi binary present and (if EXPECTED_PI_VERSION set) matches CI's resolved version
#   - new v1.0.0 base additions (pandoc, graphviz, imagemagick, yq, tealdeer)
#   - tmux 0-indexing baked in /etc/tmux.conf (required for pi-studio variants)
#   - pi-toolkit cloned at /opt/pi-toolkit
#   - pi-extensions cloned at /opt/pi-extensions
#   - pi-fork + pi-observational-memory cloned with node_modules baked
#   - entrypoint deploys pi-toolkit keybindings symlink
#   - entrypoint deploys ≥4 extensions
#   - mempalace bridge symlink present
#   - settings.json bootstrapped
#   - pi-fork + pi-observational-memory registered via `pi install`
#   - image size within threshold
