The site now ingests the sidecar's live WebSocket feed and persists it to its own MariaDB, and re-broadcasts curated events to browsers over SSE. - schema: shard_events (append-only notable-kind log, sha1 dedupe_key + INSERT IGNORE for idempotent reconnect backfill), shard_online (current players, upsert/refresh/remove), shard_economy (gold-supply series), shard_houses (per-house decay stage + derived is_idoc). - model/shardEvents + model/shardState: the .db.js/.model.js split; writes take camelCase event data, reads are shaped; online upsert uses COALESCE so a partial char.vitals refresh never blanks login fields. - utils/shardIngest: single dispatcher routing each kind to state writes and/or the event log, then the broadcaster. High-frequency kinds (char.vitals, economy.supply) update state only. A changed server.hello bootId clears the stale online roster. Deps are injected for unit testing. - utils/uoLinkSocket: the server's first outbound WS client (ws dep). Verifies the ws.hello protocol, backfills via /history + /economy on every (re)connect (dedupe handles overlap), reconnects with capped backoff, and mirrors connection state into uo_link_config. Self-guards: only connects when the integration is enabled with a token. - utils/shardBroadcast: SSE fan-out with public (safe kinds only) and admin (all) channels, keepalive pings, per-client cleanup. - server.js: start the ingest socket on boot (no-op until configured) and stop it + close SSE streams on graceful shutdown.
