+Hey everyone, this week was mostly docs and leaderboard cleanup. We filled out the new Agent Traces docs, squashed a couple of docs-delivery bugs, and gave the leaderboard's benchmark pages and results browsing a real refresh.
+
+### 🔧 Improvements
+
+*   The docs now have a dedicated Agent Traces section: product overview, the timeline and exports, and how to read traces from the API.
+
+*   The leaderboard got a rebuilt `/results` index you can filter across benchmarks, cleaner benchmark pages, and a markdown version of each page that feeds its llms.txt.
+
+*   We added more benchmark entries, plus tooling to help us find new results worth listing.
+
+### 🐛 Bug Fixes
+
+*   Stale pages no longer leak into the llms.txt output.
+
+*   Dropped a markdown content-negotiation rewrite that was serving the wrong docs.
+
+*   Leaderboard row-note tooltips now sit above their container instead of getting clipped.
+
+### 🏡 Housekeeping
+
+*   Infra now meters browser-seconds, with the billing config to match.
