🐛 Bug: aloha_run.py tries to start missing app_server.py, server never becomes ready

Environment

• OS: Windows 11 (desktop)
• Python: 3.14.2 (64‑bit)
• ShowUI‑Aloha: latest main branch (cloned from GitHub)
• Setup: followed README steps
  • python -m venv .venv
  • pip install -r requirements.txt
  • Recorded demo with Aloha.Screen.Recorder.exe
  • Parsed project with python Aloha_Learn/parser.py <project_name> to produce <project_name>_trace.json
  • Copied trace to Aloha_Act/trace_data/<trace_id>.json

---

Steps to Reproduce

1. Record a new project, e.g. fb_translation2, on Windows using Aloha.Screen.Recorder.exe.

2. Parse it:

   cd Aloha_Learn
   python parser.py fb_translation2

   This succeeds and creates:

   Aloha_Learn/projects/fb_translation2_trace.json
   

3. Copy fb_translation2_trace.json to:

   Aloha_Act/trace_data/fb_translation2_trace.json
   

4. Update Aloha_Act/prompt.json:

   {
     "trace": "fb_translation2_trace",
     "task": "Traduire en anglais tous mes articles Featurebase qui require translation"
   }

5. Run the actor:

   cd ..
   python Aloha_Act/scripts/aloha_run.py

---

Expected Behavior

• The server process should start successfully.
• The actor should load the specified trace (fb_translation2_trace) and begin executing actions on the desktop according to the task.

---

Actual Behavior

• CLI output shows the server starting but never becoming ready and then timing out, for example:

  [e2e] Launched server pid=20408 at http://127.0.0.1:7887
  ...
  Waiting for ready: 0
  ...
  [e2e] Server did not become ready in time. See logs/server_e2e.log
  

• In Aloha_Act/logs/server_e2e.log the server process fails immediately with:

  C:\Users\blorr\ShowUI-Aloha\.venv\Scripts\python.exe: can't open file 'C:\\Users\\blorr\\ShowUI-Aloha\\app_server.py': [Errno 2] No such file or directory
  

So the runner is trying to execute app_server.py at the repository root, but there is no such file in the current main branch (only Aloha_Act, Aloha_Learn, assets, etc.). The recorder and parser pipelines work, but the end‑to‑end Actor + Executor cannot run because the server entrypoint is missing or the path is outdated.

---

Notes / Questions for Maintainers

• Is app_server.py supposed to exist in the root of the repo in the current version?
• If the server entrypoint moved (e.g. into Aloha_Act), could you update aloha_run.py and the README to point to the correct path?
• A minimal working example of the current server start command would be very helpful (e.g. how you run it internally for the OSWorld benchmark).
