 ### Timeout Resolution
 
-Two-layer: adapter default + role override.
+Timeout is an **adapter concern**, not a role concern. Roles define *what to do* (prompt + schema); adapters define *how to do it* (tool, model, timeout).
 
-1. Adapter instance carries its default timeout (set at creation or from default export)
-2. Role definition can override for specific scenarios
+When different roles need different timeouts, create separate adapter instances:
 
 ```ts
 import { cursorAdapter, createCursorAdapter } from "@uncaged/nerve-adapter-cursor";
 
-// cursorAdapter has built-in default (300s)
-// Or create with custom timeout:
-const longRunAdapter = createCursorAdapter({ model: "auto", timeout: 600 });
+const fastCursor = createCursorAdapter({ model: "auto", timeout: 60 });
+const slowCursor = createCursorAdapter({ model: "auto", timeout: 600 });
 
-// Role override — review is faster
-reviewer: { adapter: cursorAdapter, ..., timeout: "60s" }
-// coder uses adapter default (300s)
-coder: { adapter: cursorAdapter, ... }
+roles: {
+  reviewer: { adapter: fastCursor, prompt: reviewPrompt, meta: reviewSchema },
+  coder:    { adapter: slowCursor, prompt: coderPrompt,  meta: coderSchema },
+}
 ```
