DanielLockyer shares a productive day: deduplicating CI workflows deleted 7,500 lines of code, fixing cache invalidation that was being blown away on almost every run, and right-sizing parallel processes made CI 40% cheaper and 15% faster. His run photo shows 16.42 km at 4'42" pace. An actionable CI hygiene playbook: dedupe workflows, fix caching, right-size parallelism.
