3- **The invariants for these files are one folder up**, in
4  `crates/postjevsql-sidecar/CLAUDE.md`, which loads with this one.

7  word.
8- **A rename is recognised only in the one unambiguous case** (one column
9  gone, one new at the same position, same type and nullability). Widening
10  the heuristic risks renaming the wrong column under a view; a drop and an
11  add is refused safely instead.
