Parallel builders were consuming reporting order, which can leave a worker waiting on a dependency while independent projects stay queued. Project-scoped builds must retain their selected project set, and reporting must remain stable regardless of worker scheduling.
The scheduling regression needs coverage of full, selected-project, and references-only builds with two workers. The larger execution-mode matrix repeats unrelated behavior and obscures that purpose.
