### Unknown function info

- [Additional libSceEsvmEngine exports](../../../core/libs/prx/libSceEsvmEngine/Export.cpp) - the 13 name/NID pairs below are defined function exports in the pinned [13.60-labelled inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libsceesvmengine-c1d3867cc5.jsonl). Their signatures and behavior are unknown; parameterless `int` declarations are import placeholders, not verified ABI prototypes. Every call throws through `NotImplemented_nid_no_patch`. No media processing, decryption or output behavior is implemented. The inventory label is not an independent console measurement.

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/libSceEsvmEngine/Export.cpp) - 26 entries observed in a 3.20-labelled image and a later 13.60-labelled image are import-resolution declarations only. Neither image label authenticates a retail firmware version. 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. 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).

[Version-pinned selected ELF export records](https://gist.github.com/kyon-eth/752e1b1d4a6ac8a26c97e693527fefbd/a7bddd315c7740a7d065af9e80b0447fcd5b91be) list every NID below with its image label, decoded export module and library, raw qualified symbol, ELF function type, value and size for each inspected version-labelled module. The extract SHA-256 is `63256453dc9620091ce6af95f8b243b7da8f2ce76a585f4886f76aa6625b5b21`; its full-module sorted-function-NID digests and raw module-parameter words permit independent comparison. The extract is an analyst-produced metadata record, not independent authentication of the original images or proof of prototypes or behavior. The separately published 3.20 source catalog has a module file but none of these selected NIDs.
