"""Synthetic seed used on both commits. Run from either installed checkout while its
fresh T3 dev server runs with T3CODE_DEV_SEED=0. Then follow the UI steps below.

UI driver (T3 preview tools, Chromium 1280x800 CSS pixels):
1. Open checkout-A in IntelliJ IDEA Community 2025.2.4 on Linux/Xvfb 1920x1080.
2. Open the created Checkout-B thread. Set preferred editor to IntelliJ IDEA.
3. Hide thread details. Right-click Greeter.java L7:C16 in the replay response;
   choose Open in IntelliJ IDEA. Observe IDE project header and position status.
4. On head choose New Window and Trust Project when prompted.
5. Close B's IDE window and any externally opened file in A before the next case.
6. Open the thread terminal. Print src/Greeter.java:3:14, clear the prompt, and
   Ctrl-click the printed path. Observe project header and position status.
7. On head choose New Window. Check B at 3:14. Base retains A while displaying B.

The recording files show the T3 interaction followed by the concurrent IDE
recording. Paths are redacted. No app launch/navigation code was changed; only
the replay fixture text was replaced identically on both commits.
AI-assisted; verified with the tests and tools listed above.
