# libSceFsInternalForVsh technical debt

### Silent stubs

- [sceFsErriCtl and sceFsErriGetState](../../../core/libs/prx/libSceFsInternalForVsh/Export.cpp) return 0x8002002d without managing error reporting control or state.

The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified

### Additional callable exports

- [Additional callable exports](../../../core/libs/prx/libSceFsInternalForVsh/Export.cpp) - 163 entries present in both version-labelled images are import-resolution declarations only. None is listed in the pinned public 3.20 catalogue for this library. Neither label independently authenticates retail firmware provenance. Parameter lists, return types and behavior are unverified; parameterless `int` declarations are placeholders, not verified ABI contracts. Every entry throws through `NotImplemented_nid_no_patch`. Unidentified names use literal NID aliases. No runtime functionality is implemented. Data exports require separate layout and ownership analysis. Identified candidate names match their NIDs in the [public symbol database](https://github.com/zecoxao/sce_symbols/blob/2883963a0a514ba6e77407a08ef4730a65e88254/aerolib.csv) or [supplemental catalog](https://github.com/claimore22/ps5rs/blob/2304be5131221bae0dac24b9767cabffda33f747/data/nids.csv).
