All RPCD scripts must use the 'luci.' prefix to match their JavaScript ubus object declarations. This fixes RPC errors like: - "RPC call to luci.cdn-cache/status failed with error -32000: Object not found" Renamed RPCD scripts: - cdn-cache → luci.cdn-cache - client-guardian → luci.client-guardian - crowdsec → luci.crowdsec-dashboard - netdata → luci.netdata-dashboard - netifyd-dashboard → luci.netifyd-dashboard - network-modes → luci.network-modes - system-hub → luci.system-hub - wireguard-dashboard → luci.wireguard-dashboard 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
