libSceNKWebKitRequirements technical debt

Known export names; ABI prototypes unverified

• 83 pending exports in Export.cpp are present in the PS5-3.20_Libs inventory. Their prototypes and behavior are unverified. They use the no-parameter import-resolution convention and throw through NotImplemented_nid_no_patch; these declarations make no ABI or behavior claim.
• The 72 of them declared in Identified.hpp carry the zlib, libjpeg, libpsl, libxml2 and UndefinedBehaviorSanitizer names whose tools/nid_names.py hash equals the inventory NID; the names were taken from the identifiers of the zlib 1.3.1, libjpeg-turbo 3.0.4, libpsl 0.21.5 and libxml2 2.13.4 sources and from the two __ubsan_handle_cfi_check_fail handlers libkernel_sys exports. A name match does not show that the console function has that library's prototype or behavior. The other 11 hash to no identifier of those sources or of SQLite 3.46.1, ICU 76.1, HarfBuzz 10.0.1, cairo 1.18.2, pixman 0.42.2, FreeType 2.13.3, libpng 1.6.44, Expat 2.6.3, libxslt 1.1.42, libwebp 1.4.0, Brotli 1.1.0, WOFF2 1.0.2, curl 8.10.1, Little CMS 2.16, OpenJPEG 2.5.2 and Fontconfig 2.15.0.

SQLite adapters

• The 50 sqlite3_* exports in Sqlite.cpp assume the public SQLite C prototypes because their names hash to the inventory NIDs; the console prototypes are not confirmed. They call SQLite 3.54.1 built from 3rdparty/sqlite with SQLITE_THREADSAFE=1 and SQLITE_OMIT_LOAD_EXTENSION. The console library's version and compile options are unknown.
• sqlite3_open_v2 ignores the guest VFS name and uses the host default VFS. It maps file names through the guest path resolver, but passes :memory:, empty names and SQLITE_OPEN_MEMORY on a name that is not a file: URI unchanged. A file: URI opened with SQLITE_OPEN_URI passes unchanged only when its path is exactly :memory: or mode=memory is the last mode query parameter and the URI has no %; every other such URI throws through NotImplemented_nid_no_patch. A database that exists only inside app0.zar is refused. SQLite writes the database and its -wal, -shm and -journal files on the host directly; a read-write open records those paths so sceKernelSync flushes them, but SQLite's own sync calls are not routed through the guest file layer.
• sqlite3_open_v2 installs a host authorizer on every connection it opens that denies ATTACH DATABASE of any non-empty name, so a guest ATTACH or VACUUM INTO fails with SQLITE_AUTH instead of writing a host path that skips the guest path resolver; ATTACH '' and a plain VACUUM still work. The guest's own sqlite3_set_authorizer callback runs after it and cannot lift it. Resolving the guest path for those statements is not implemented.
• sqlite3_bind_blob and sqlite3_bind_text16 copy data given with a guest destructor and call that destructor before returning, instead of when SQLite releases the value.
• sqlite3_wal_hook returns the host's previous argument, such as the default autocheckpoint frame count, until a guest hook is installed.

Additional callable exports

• Additional callable exports - 32 entries present in both version-labelled images are import-resolution declarations only. Neither label independently authenticates retail firmware provenance. These NIDs are absent from the pinned public 3.20 catalogue. 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.
