- build_sln now trusts UnrealBuildTool's "Result: Succeeded" (and absence of
real compile errors) over MSBuild's exit code, which is non-zero for a side
project even when the UE game module built fine.
- Fixed double event-listener registration (async unlisten under StrictMode)
that duplicated every p4-log / p4-transfer / build-log line.
- Build overlay can be minimized to a small floating chip (spinner while
building, ✓/✗ when done), click to expand, × to dismiss.
