+"""Tests for the terminal result cwd echo (feat/terminal-cwd-echo).
+
+When a command changes the session working directory, the tool result
+gains a "cwd" field so the model stops prefixing every command with
+'cd X && ' (60% of production terminal calls) and stops running pwd
+diagnostics after directory changes.
