Acceptance-check finding (concurrency): the worktree lock in windev-worker-ci.ps1 guarded the build stage, but run-windev-ci.sh's bootstrap did git fetch + git checkout on the shared C:\build\mxaccessgw-ci clone BEFORE that lock was taken. Two concurrent runs therefore collided on .git/index.lock at the bootstrap stage (the second failed 'Another git process seems to be running', exit 1) instead of the second waiting — defeating the lock's purpose for manual/degraded-mode overlap or a future second runner. (The single Gitea runner serializes jobs, so CI pushes never actually overlapped; this is defense-in-depth being restored.) Fix: the bootstrap now acquires the same mkdir worktree lock around its fetch/ checkout and exports MXGW_CI_LOCK_HELD; windev-worker-ci.ps1 re-uses that lock (skips re-acquire/release) when the env is set, and still self-locks for a standalone/manual run. Now the second concurrent run waits at the bootstrap.
