These changes were implemented with accompanying tests and tooling updates; commits listed below. Overall impact: improved reliability and efficiency in distributed test environments, faster feedback in CI, and lower risk of overload in backends. Skills demonstrated include distributed systems hardening, CI/CD optimization, YAML-based configuration handling, and data-driven decision making using results.json and jq. Key commits: - 84e08ed98efd4f30c2e780358e8ac73fbb3a9383 (Task Execution Spread Limiter; tests: adding a tasks limit number in spread.yaml) - 5fdebe1d7fe6a145b5d713c1dc1f38c21cd2c570 (CI Test Re-run Optimization Using results.json; migrate re-run logic to use results.json)
