📝 Walkthrough

Walkthrough

The muse submodule reference now points to commit eb6dddd5e05aec19ee1789708c60fda6fdad7a34. Project save and open dialogs now use [experimental] in relevant file-format labels. File extensions and supported formats remain unchanged.

🚥 Pre-merge checks | ✅ 2 | ❌ 3

❌ Failed checks (2 warnings, 1 inconclusive)

Check name	Status	Explanation	Resolution
Out of Scope Changes check	⚠️ Warning	The seven label changes from parentheses to brackets do not address the linked issue's .txt preset filter and appear unrelated.	Remove the unrelated format-label changes or document their required relationship to issue #8166.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Linked Issues check	❓ Inconclusive	The main fix is hidden in the updated muse submodule, so the provided diff does not confirm that Linux preset filters now include .txt.	Provide the submodule diff or test evidence showing that importing AU4 presets exposes .txt files in the native Linux file picker.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title identifies the primary change: a Linux native file picker fix.
Description check	✅ Passed	The description links issue #8166, records testing context, and completes the required checklist except the optional test item.
