-//   this module.
-// - A dependency on this module from sg/sg/lib/codeintel/lsif/protocol/reader
-//   for the conversion functionality, as it needs access to generated

-// There doesn't exist a reliable bijection between SCIP and LSIF.

-// This conversion is lossy because SCIP includes metadata that has no equivalent encoding in
