# preflight.sh — design plugin dependency health check.
# Thin shell wrapper over `node cli/lib/preflight.mjs --plugin design`.
# Keeps the detection logic in one place (the .mjs lib) while exposing the
# bash-friendly modes (--shell-export, --warn-only) that init.md and the
# SessionStart hook need.
#
# Usage:
#   preflight.sh                    # text table (humans)
#   preflight.sh --json             # machine-readable envelope
#   preflight.sh --shell-export     # `export DEPS_OK=... DEPS_MISSING=...`
#   preflight.sh --quiet            # silent on success, one-liner on miss
#   preflight.sh --warn-only        # same as --quiet (SessionStart hook)
#
# Resolution (DDR-045): never compute paths from `dirname $0` inside a
# `bun --compile` standalone binary — that maps to /$bunfs/root.
#
# Resolution (DDR-061): in a MARKETPLACE install the plugin is copied alone into
# `cache/<marketplace>/<plugin>/<version>/` — there is NO sibling `$PKG_ROOT/cli/`.
# So: use the sibling `cli/lib` when it exists (running uncompiled from the repo
# or an npm package, where cli/ is present); otherwise reach the check through
# the on-PATH `maude` binary (a declared plugin dependency), which resolves the
# manifest from its own package root. Fixing a straggler — the relative-path
# crash (`Cannot find module …/cache/maude/cli/lib/preflight.mjs`) that the cache
# steps already avoid by calling on-PATH `maude`.
#
# Exit: 0 if all hard deps pass; 1 otherwise.
