most of us just build pipelines to push data to the warehouse and call it a day. the real nightmare starts when you gotta prove to a regulator that your numbers havent been tampered w/ since they were first logged. instead of treating compliance like some
random task downstream chore, we need to bake lineage and immutability directly into the initial architecture. if you cant run
reconstruct_state(timestamp="2024-05-12")
w/o breaking everything, your setup is fundamentally broken. never wait until a request hits your desk to realize your data lacks point-in-time reconstruction capabilities.
if you can't prove the past, you don't actually own your datamore here:
