- * 2. Interactive sessions open a TTY
- * 3. Input can be sent to the terminal
- * 4. Output is received from the terminal

 /**
  * @fileoverview Global test setup for Claudeman tests
  *
- * Provides:
- * - Session concurrency limiter (max 10 tmux/screen sessions)
- * - Tracked resource cleanup (only kills what tests create)
- * - Global beforeAll/afterAll hooks
+ * SAFETY: TmuxManager and ScreenManager have built-in test mode detection
+ * (via process.env.VITEST) that makes ALL shell commands no-ops.
+ * This means tests CANNOT kill, create, or interact with real tmux/screen
+ * sessions regardless of what the test code does.
  *
- * CRITICAL SAFETY GUARANTEES:
- * 1. Pre-existing screens/tmux sessions (captured at MODULE LOAD) are NEVER killed
- * 2. Current process screen ($CLAUDEMAN_SCREEN_NAME) is NEVER killed
- * 3. Only sessions explicitly registered via registerTestScreen()/registerTestTmuxSession() can be killed
- * 4. All session names must pass validation before being accepted
- *
- * This setup ONLY cleans up resources that the test suite itself creates.
- * It will NEVER kill Claude processes or sessions that weren't spawned by tests.
- * This makes it safe to run tests from within a Claudeman-managed session.
+ * This setup file only handles mock/timer cleanup between tests.

 /**
- * @fileoverview Integration test for tmux session recovery after server restart.
+ * @fileoverview Unit tests for tmux session recovery after server restart.
  *
- * Tests the full restart cycle:
- * 1. Create a WebServer with real tmux backend
- * 2. Create a session (tmux)
- * 3. Stop the server (without killing tmux sessions)
- * 4. Start a new server instance
- * 5. Verify session is recovered via reconcileSessions()
+ * Tests verify the test mode safety behavior of TmuxManager:
+ * - In test mode (VITEST=1), reconcileSessions never runs real tmux commands
+ * - All registered sessions are reported as alive
+ * - No real sessions are discovered
+ * - No state files are read/written
  *
- * Port: 3152
+ * SAFETY: No real tmux sessions are created, killed, or interacted with.
+ *
+ * Port: N/A (no server needed)
