- 01 Catalogues, Metadata and Discovery The three kinds of metadata a catalogue holds, why the technical layer is the only one that stays accurate for free, and what makes a catalogue get used rather than abandoned.
- 02 Column-Level Lineage What lineage answers that a dependency graph cannot, why column granularity changes the questions you can ask, and the parsing problem that makes it hard to capture correctly.
- 03 Data Classification and Sensitivity Labelling Why a sensitivity scheme is only as good as how labels propagate through joins, aggregates, embeddings and models, how the high-water-mark rule makes propagation mechanical, and the over-classification and inference failures that quietly turn labels into noise.
