The Linux release validator still exhausted process and socket timing with two Vitest workers, causing unrelated OpenCode and private-endpoint tests to fail. Run test files with one worker so process-backed integration tests remain deterministic within the existing CI job budget.
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.
Establish the Electron foundation and pluggable agent runtime so desktop workflows can evolve safely across supported platforms.
