+## 目标

+Close the audited gap between classified feature routes and real browser/server execution.

+
+## 验收
+
+- SERVER_NATIVE performs a real bounded HTTP Blender background job and returns a mutated blend
+- F3 loads typed operator properties on demand
+- browser-equivalent routes invoke existing browser workflows
+- verification remains incremental and behavioral evidence stays explicit
+
+## 失败边界
+
+- missing provider, malformed envelope, hash mismatch, timeout, cancellation and context-only operators fail closed
+- failed turns remain pending and never publish false completion
