Can Travis CI matrix jobs be forced into a deterministic execution sequence?
Travis CI utilizes the matrix key in .travis.yml to execute parallel job variations. While these jobs are defined in a specific order within the configuration file, the scheduler prioritizes resource utilization, which often results in non-deterministic start times and execution sequences across different builds. This behavior introduces uncertainty when bui
