Docstrings keep their usage and exit codes; table headers keep the column contract and the client addresses and lose the dates, the correction history and every path into another repository. A generated header changes in its generator's template, so each of the four generators still reproduces its output byte for byte, and no data row changed in any of the seven tables.

r"""Generate `crates/benilla-ui/src/messages/catalog.rs` from `reference/1.12-message-catalog.tsv`.

The table is the reference's message registry at `0xb4b498`, which `CGGameUI::DisplayError`
|
|
`0x496720` indexes by message id; this re-shapes it into a Rust static that ships with benilla.

It refuses rather than emits on a non-dense id range, a duplicate key or an unknown kind.
