scrupulous

This word carries a dual weight of precision and conscience. When used to describe a process, it evokes an image of microscopic attention where no single detail is overlooked, often implying a high level of professionalism or obsession with accuracy. When applied to character, it suggests a rigid internal moral compass. It describes a person who is not just honest, but actively anxious about the possibility of being dishonest or unfair, making it more intense than simply being truthful.
