# Bundled-artifact model (v1.8.147+): the Linux CLI companion + the Claude skill
# bundle ship INSIDE this package's tarball (dist/linux/, skills/). We SYMLINK
# them onto PATH / into ~/.claude/skills. Self-contained since v1.9.116: no
# external helper CLI is required (the pre-1.9.116 script hard-required the
# retired `adompkg` tool, so `adom-wiki pkg install` failed and rolled back on
# any container without it — wiki discussion #117). No download, no
# version.json dependency: the binary is right here, SHA-fixed by the published
# tarball.
#
# What it does NOT do: install the Windows/macOS GUI. That runs on the user's
# laptop (the signed Windows installer is a wiki release download; AD
# auto-updates itself). The skills tell Claude how to get the GUI onto the
# laptop.
