# libharfbuzz technical debt

### Callable exports

- [Callable exports](../../../core/libs/prx/libharfbuzz/Export.cpp) - 35 callable NIDs match the [public 3.20 catalogue](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libharfbuzz.c) and the [selected export metadata](https://gist.github.com/kyon-eth/510aa3fcaf09cbe8b52048b44e4e67c0/b909f17c99ecd6323c085f70064548789062d57e) from an older `libharfbuzz` image and a later `libSceVshHarfBuzz` image (SHA-256 `25af97e02c1fa8d318ff3697eb8a79057ee9b8c5e5e4ec321f25114aceb05628`). The later image has a different module and library identity; matching NIDs do not establish forwarding or equivalent behavior. The version labels are not authenticated. Prototypes and behavior are unverified; these declarations throw through `NotImplemented_nid_no_patch` and implement no runtime functionality.
