+- **New** · Overview stats: request outcome mix (ok / incomplete / error / canceled), cache hit rate, streaming share and canceled requests; the account pool lists cooling accounts with reason, countdown and backoff level, plus the session-affinity hit rate.
+- **New** · Overview drill-down: click a model, account, provider or error kind, or drag a range on the traffic chart, to open the matching logs. Time windows add 30d and custom; stats auto-refresh every 30s and can be paused.
+- **New** · Usage page with sortable tables by model, account and provider (requests, success rate, p95, tokens, cache, credits). The traffic chart switches between requests, tokens and latency.
+- **New** · Live concurrency: an overview strip (in-flight vs. capacity, last 60s), per-account in-flight bars and a sidebar indicator.
