Additional callable exports

• Additional callable exports - 8 entries present in both version-labelled images are import-resolution declarations only. 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 or supplemental catalog.

Functional

• Registry store (libSceRegMgr) - entries are queried through an in-memory process-local store without persistence. Callable prototypes for sceRegMgrGetInt, sceRegMgrGetStr, and sceRegMgrGetBin derive from regmgr.h. Implemented getters return error codes for invalid parameters (0x80820001), missing keys (0x80820002), buffer sizing (0x80820004), and type mismatches (0x80820006) as unverified host implementation assumptions, as the cited regmgr.h does not establish error codes or validation behavior. Queries with non-positive keys 0 and -1 take the missing-key path without key-range validation, pinning the unverified host assumption that non-positive keys are not rejected as invalid parameters. Setters (sceRegMgrSetInt, sceRegMgrSetStr, sceRegMgrSetBin, sceRegMgrSetbin), reset (sceRegMgrResetVal), and zero-length getter paths remain unimplemented throwing NotImplemented_nid_no_patch until callable contracts and error codes are supported by evidence.
• Unverified registry APIs (libSceRegMgr) - export names and NIDs for initial-value getters, version queries, region queries and conversions, error checks, control/backup routines, and sceRegMgrNonSys* variants are present in the PS5 3.20 export inventory and NID database, but their callable contracts and runtime behavior remain unverified and retain NotImplemented_nid_no_patch.
