 - [x] **Y4-03** — Added opt-in analytics backend. RPC endpoints: analytics.get-status, analytics.enable, analytics.disable, analytics.get-snapshot. Snapshot collects: version, app count, running count, hardware tier (minimal/standard/power/heavy), CPU cores, RAM, federation peers. No PIDs, no DIDs, no IPs. Opt-in stored in analytics-config.json. (Dashboard UI and relay-based aggregation deferred.)
 
-- [ ] **Y4-04** — Cross-chain support (Monero, Liquid). Add support for Monero full node and Liquid sidechain containers. Federation supports multi-chain status reporting. **Acceptance**: Can run Bitcoin + Monero + Liquid on same node.
