# install.sh — host-install hook for the openclaw runtime.
#
# Why this exists
# ---------------
# openclaw's npm package (openclaw@2026.4.29 at time of writing) pins
# `engines.node >= 22.14.0`. The default Ubuntu 24.04 workspace AMI
# ships Node 18.19.1 from apt. When adapter.py:setup() runs
# `npm install --prefix ~/.local -g openclaw` against Node 18, npm
# either fails outright or surfaces a successful install whose
# postinstall scripts crash on first invocation — both end as
# `RuntimeError: Failed to install OpenClaw` from adapter.py:71, the
# molecule-runtime never binds port 8000, and the workspace flips to
# status=failed within ~2 minutes of provision.
#
# Diagnosed 2026-05-01 from /var/log/molecule-runtime.log on a failed
# provision:
#
#     RuntimeError: Failed to install OpenClaw: npm WARN EBADENGINE
#       package: 'openclaw@2026.4.29',
#       required: { node: '>=22.14.0' },
#       current: { node: 'v18.19.1', npm: '9.2.0' }
#
# What this does
# --------------
# Installs Node 22 LTS from nodesource into the system PATH. apt is
# the standard way to install Node on Ubuntu and matches openclaw's
# own README. The runtime user has passwordless sudo on the AMI, so
# we don't need to fall back to a user-local tarball install. Node 22
# is the LTS line that openclaw upstream targets.
#
# Idempotent — if Node ≥22 is already on PATH (e.g. AMI gets bumped
# in a future cycle and this hook becomes a no-op), early-exits 0
# without touching apt.
#
# Tracked: this is template-local "system deps" workaround. The
# durable fix is bumping the workspace AMI to ship Node 22 directly,
# which would also benefit gemini-cli and any future Node-based
# runtimes. Until then, this hook keeps openclaw provisioning green.
