+Feature: Bug #1141 — session create persists for session list
   As a developer
   I want to verify that a session created via `agents session create`
   appears in a subsequent `agents session list`
-  So that the persistence bug is captured and will be caught by a regression test
+  So that the session CRUD lifecycle works end-to-end
 
-  The bug: `agents session create` succeeds (exit code 0) but the created
-  session does not appear when `agents session list` is invoked immediately
-  after. This test captures bug #1141 and intentionally keeps
-  `@tdd_expected_fail` so CI passes while the bug remains unfixed.
+  Fixed: The A2A facade handler now skips creation when a session_id is
+  already supplied in the params, preventing duplicate sessions (#1141).
 
   Scenario: Init then create should make list total increase from 0 to 1
     Given a CLI runner using the real session DI path
