opencode-devbox/scripts/smoke-test.sh

#!/usr/bin/env bash
# Smoke-test a freshly-built opencode-devbox image.
#
# Verifies:
#   - Core binaries are on PATH and runnable
#   - opencode itself starts and prints a version
#   - Entrypoint runs cleanly as non-root after UID adjustment
#   - Generated opencode.json has the expected shape
#   - MCP wrapper works (when mempalace is installed)
#
# Usage: ./scripts/smoke-test.sh <image> [--variant base|omos]
#
# Exit codes:
#   0  all checks passed
#   1  one or more checks failed
