# Multi-stage build: install + build native deps in stage 1, copy the
# resulting node_modules into a slim runtime image in stage 2. The
# node-gyp install hook auto-fired by npm needs python3/make/g++ to
# evaluate binding.gyp even when the prebuilt N-API binary is used.

# Run as root. The bind-mounted /data volume on Unraid (and most hosts) is
# owned by UID 99 ("nobody") with mode 0775, so the official image's
# unprivileged "node" user (UID 1000) cannot create life.db inside it and
# the container fails with SQLITE_CANTOPEN on boot. Root inside a single-
# purpose app container with no exposed shell is fine for this use case.

# lib/ holds the runtime modules (lib/user-model, lib/sync/plex,
# lib/sync/kavita, lib/calendar-sources, lib/graph-source, lib/dedup,
# lib/health-checker, lib/secret-box, lib/snapshot, lib/agent-tokens,
# lib/agent-endpoints, lib/drawer-dispatcher). server.js requires
# './lib/user-model' at boot, so dropping this directory in the
# runtime stage leaves the container unable to start with
# `Error: Cannot find module './lib/user-model'` (PHA-2001).
