Build story
This is the one project where I wrote most of the code myself, because the model kept producing plausible SQL that was subtly wrong about lock behaviour. It was genuinely good at the rendering layer and genuinely bad at the parser. Next time I would split the prompt by subsystem rather than describing the whole tool at once.
About
Point it at two Postgres schemas and it renders the real difference, including the constraint and policy changes most diff tools skip.
