 ### Changed
 
+- The product and technical gap baseline now records the ten open PRs,
+  exact-head governance state, and current provider-backed Strix evidence.
 - Web requests now use the native `SOMAXCONN` listen backlog and HTTP/1.1
   persistent connections, while the existing per-request daemon threading and
   explicit run-slot admission keep slow provider I/O from blocking liveness.
