v0.1.12
Patch release: Windows installer parser fix (PW #11).
Fixes:
installer/sparrow-engine-install.ps1+probe.ps1+probe_gpu_quality.ps1— prepend UTF-8 BOM so Windows PowerShell 5.1 (the default shell on Windows 10/11) reads the files as UTF-8 instead of Windows-1252. Previously the em-dash / right-arrow / section-sign characters mis-decoded into garbage tokens, producing parser errors before any code ran (PW077caf2).

Known issue (resolved post-release): this Release page has 6 of 8 CLI tarball assets; the Windows CPU CLI tarball (sparrow-engine-cpu-0.1.12-windows-x86_64.zip) failed to build due to an env-var-name collision between ilammy/msvc-dev-cmd@v1 (Platform=x64) and the YAML step (PLATFORM=windows-x86_64) on Windows + MSYS Git Bash — see OQ-2026-05-27-2. The bug is filed as RP-21 and fixed on sparrow-engine-dev HEAD (PW 17e81fc, verified GREEN via run 26547501057). The next vX.Y.Z tag-push will attach all 8 CLI tarballs cleanly.
