A stray commit buried multiple levels deep cost me months

A developer spent months planning a major code migration only to discover deep in their work that hidden database commits buried multiple levels within function calls were breaking transaction atomicity. The issue stemmed from poor code organization where database operations and commits were obscured across abstraction layers, making it impossible to understand that methods were committing transactions when called from within transaction contexts. The author emphasizes that responsibility lies solely with the programmer for creating unclear abstractions that hide side effects, not with frameworks or business requirements.
