 ## R1 — P2: Reject raw helper command names as legacy module selectors
 
+**Completed.** The legacy entry point now checks its three module selectors
+before delegating to the helper, retaining the single profile/module mapping
+there. Regression cases cover all three raw-command collisions and require
+usage status 2 with no Go invocation. The new regression failed before the fix;
+the complete focused scripts suite and shell syntax checks passed afterward
+with Go 1.26.8, including valid legacy and direct raw-command forwarding.
