# Extracts /tmp/network-source.tar.gz on a VPS and places everything correctly.
# Run as root on the target VPS.
#
# What it does:
#   1. Extracts source to /home/debros/src/
#   2. Installs CLI to /usr/local/bin/orama
#   3. If bin-linux/ is in the archive (pre-built), copies binaries to their locations:
#      - orama-node, gateway, identity, rqlite-mcp, olric-server → /home/debros/bin/
#      - coredns → /usr/local/bin/coredns
#      - caddy → /usr/bin/caddy
#
# Usage: sudo bash /home/debros/src/scripts/extract-deploy.sh
#   (or pipe via SSH: ssh root@host 'bash -s' < scripts/extract-deploy.sh)
