setup: don't list the shared Chat settings file as a model config (KeyError: 'exe')

[xidus90]

Problem

Once Chat settings have been saved for all clients in the web UI, START-HERE.bat lists the settings file as a model of its own. Picking it crashes:

  1) qwen3.8-flash-next-iq3_s
  2) strata-iq3_s.shared-settings
  3) install another model / change settings
Which one? [1]: 2
Traceback (most recent call last):
  ...
  File "setup.py", line 1717, in start
    missing = [p for p in [cfg["exe"], *[a for a in cfg["args"] if a.endswith(".gguf")]] if not Path(p).exists()]
KeyError: 'exe'

Service.set_shared() in serve/server.py writes the settings to strata-<model>.shared-settings.json next to the config (serve/server.py:2042). That name matches the strata-*.json pattern setup.py uses to find model configs. Anyone who has saved shared settings once has the file, and resetting the settings deletes it again.

Fix

A new helper, model_configs(folder), lists strata-*.json without *.shared-settings.json. All three places that globbed for configs now use it:

• installed_configs(): the start menu (the crash above).
• previous_config(): "set up like the last one" from another install. The settings file is written after the config, so max(mtime) could pick it there, and choices_from_config() would then read empty args.
• the model-file move, which repoints configs to the new data folder. Harmless before, since the settings file holds no paths; changed only so all three places are consistent.

Name-based filtering is sufficient. serve/server.py, setup.py and tools/calibrate.py write no other strata-*.json next to a config, and calibration results go into the config's own args.

Tests

python -m unittest tools.test_setup_configs

The three new tests fail on main and pass with the fix. The existing tools.test_setup_pins, test_setup_amd, test_setup_lowram, test_setup_rope, test_calibrate and test_shards still pass (61 tests). previous_config() also scans the Strata* folders next to the checkout, so the tests patch other_installs() to keep real installs on the test machine out.

Tested on Windows 11 with Python 3.13. On a real install with both files, the menu now lists only strata-iq3_s.json.

I found no existing issue or PR for this.

Fixed in 0.1.40: model_config_files() leaves the shared Chat settings file out in the start menu, in 'set up like the last one', in the data-folder move and in the MCP server's config list. Thanks for the report and the tests.
