+# veb integration tests
+
+These tests use `veb.Context` in memory. They do not start a `veb` server, bind
+a port, or depend on HTTP client/server timing.
+
+The coverage target is narrow: `x.async` can bound and propagate errors for a
+synthetic veb handler step without becoming part of `veb`'s runtime or server
+lifecycle.
