# Deploy the AIUI (Chat mode iframe) build to an Archipelago server.
#
# Usage:
#   ./scripts/setup-aiui-server.sh <host>
#   ./scripts/setup-aiui-server.sh archipelago@192.168.1.198
#   ./scripts/setup-aiui-server.sh archipelago@192.168.1.228
#
# What it does:
#   Rsyncs (or tar+scp, if rsync is unavailable on the target) a locally
#   built AIUI dist/ into /opt/archipelago/web-ui/aiui/ on the target node.
#
# What it no longer does (13-02-PLAN.md — closing a live production
# exposure): it used to also patch nginx to route /aiui/api/claude/ to a
# standalone Python proxy holding its own ANTHROPIC_API_KEY, with no session
# gate — anyone who could reach the node's web port could spend the owner's
# API budget. That proxy, its systemd unit, and this script's nginx-patch
# step are all deleted (see scripts/deploy-to-target.sh's "Removing legacy
# Claude API proxy sidecar" step). AIUI's Claude/Ollama calls now route
# through the Rust daemon (127.0.0.1:5678), which enforces the session
# cookie itself and reads the node's single key ledger. Set the key via
# `system.settings.set claude_api_key` (Settings > AIUI in neode-ui) — this
# script has nothing to do with the key anymore.
#
# Prerequisites:
#   - SSH key access to target server
#   - AIUI is built automatically (via scripts/build-aiui.sh) when its dist
#     is missing or stale — D-19 (2026-08-03): AIUI lives in-repo at aiui/
#     now, so there is no second checkout to build separately first.
