| The Computed Column Chaos | Complex formulas everywhere | Formula documentation |
| The Cross-DB Dragon | Linked servers and remote queries | Spec-driven refactor |
| The Lost Knowledge | "Only Bob knows how this works" | Automated reverse engineering |
| The Validation Void | Did we migrate everything? ๐คท | Spec-generated test suite |
