Tree sitter grammars generate a complete/concrete syntax tree with incremental updates, they necessarily have to be able to represent invalid source text (because users will type it!).

If you're using a tree-sitter grammar as the input to a compiler (which is not what its designed for) you need to write a pass to convert from CST to AST, as you normally would.

No, I specifically said "accept invalid syntax but not mark the parse trees as bad". Tree-sitter is supposed to accept invalid syntax, yes, but also tag the nodes as such. And at the time it seemed upstream didn't intend to fix the edge cases where it fails to do so, it just gave syntax trees that didn't match the grammar.
