The Linux routing test still referenced the obsolete bin/opencode name. With intentional path-only Runtime selection, that stale fixture was no longer masked by automatic discovery; use the locked opencode-ai 1.18.9 bin/opencode.exe entrypoint on every platform.
Keep the approved 0.12.0 notes and bilingual feature matrices explicit that local OpenCode paths are not prevalidated and fail only at actual launch.
Full-suite resource contention could make asynchronous renderer assertions and short runtime timing tests fail even though focused runs passed. Limit Vitest to two workers and give the affected UI operations the existing three-second async window.
Also include the approved Linux ARM OpenCode startup note in both feature matrices and release-note languages, and record the successful isolated Linux x64 Host validation of the current-source Runtime activation path.
Update the desktop version, approved bilingual release notes, and synchronized English and Chinese feature matrices for the 0.12.0 candidate.
Release preparation now runs local tests, type checks, and lint without a local production build, then requires the main-branch CI build before tagging. The package matrix uses a native Windows arm64 runner and validates managed Python on every target without adding extra license files to the desktop package.
