 - PPSA07411 imports declared without parameters, signatures unknown, added without an implementation because the title fails to load without them: [sceSslCreateConnection, sceSslDeleteConnection, sceSslEnableVerifyOption, sceSslConnect, sceSslRead, sceSslWrite](../../core/libs/prx/libSceSsl/Export.cpp) (libSceSsl), [four sce::Json::Value members (setElementAccessFailureHandler, setSpecialFloatHandler, setTypeMismatchHandler, operator bool)](../../core/libs/prx/libSceJson2/Export.cpp) (libSceJson2), [sceConvertKeycodeGetCharacter](../../core/libs/prx/libSceConvertKeycode/Export.cpp) (libSceConvertKeycode) and [sceNpSessionSignalingGetGroupFromSessionId](../../core/libs/prx/libSceNpSessionSignaling/Export.cpp) (libSceNpSessionSignaling)
 - [Comparison-sampled R32 float and R16 unorm textures](../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) (libSceAgcDriver) whose surface a storage image holds are sampled from a D32_SFLOAT or D16_UNORM image that the GPU refills from the storage image whenever its version moves, because Vulkan compares only depth formats. Only surfaces of at least 1 MiB (`APS5_DEPTH_COPY_MIN_KIB`) that are not 3D take the copy; smaller ones stay CPU snapshots compared against guest memory. With copies of small surfaces, one title hit an intermittent boot-time crash that was not explained.
 - [Null vertex buffer V#](../../core/libs/prx/libSceAgcDriver/Graphics/include/VertexInput.hpp) (libSceAgcDriver) - a V# whose four dwords are all zero is bound to a zeroed vertex buffer of the attribute's size with stride 0, so every component of its attribute reads 0. This follows the V# fields in the [AMD RDNA2 ISA](https://gpuopen.com/download/rdna2-shader-instruction-set-architecture.pdf) (`NUM_RECORDS` 0, `DST_SEL` 0 selects 0), not measured on hardware.

 - [Descriptor pool recycling](../../core/libs/prx/libSceAgcDriver/Graphics/src/ShaderResources.cpp) avoids individually freed sets: [RADV 26.2.2](https://gitlab.freedesktop.org/mesa/mesa/-/blob/mesa-26.2.2/src/amd/vulkan/radv_descriptor_pool.c) initializes its free-set heap with 32 bytes beyond the backing allocation. An allocation-only RX 6600 test reproduces acceptance of a 4,128-byte set in a 4,096-byte pool; the path without individual frees rejects it. Pools reset after their last set is released. A cached set can retain unused slots in an exhausted pool until eviction; peak gameplay pool memory remains unmeasured.
 - [_fstatfs](../../core/libs/prx/libkernel/File/src/Stdio.cpp) (libkernel) fills the FreeBSD 11 `struct statfs` of the PS5 payload SDK with the host volume that holds the file: block size, transfer size, total, free and available blocks, maximum name length and the read-only, `nosuid` and `noexec` flags (on Windows only read-only, and `f_files` and `f_ffree` are 0, as NTFS has no fixed number of files). The filesystem type number and name, mount paths, owner, filesystem id and I/O counters are left 0 or empty, since they would describe a host mount, not a console one. Sockets and pipes return `EINVAL`, as FreeBSD's `getvnode` does; a Windows descriptor that is neither a file nor a pipe throws. Stremio Plus (PPSA74126) reads the free space before a download and only logs the other fields
 - [fstatvfs](../../core/libs/prx/libSceLibcInternal/FilesystemStatistics.cpp) (libSceLibcInternal) converts `_fstatfs` to the 88-byte `struct statvfs` as FreeBSD 9.2's `sfs2svfs` does (`f_bsize` from the transfer size, `f_frsize` from the block size, `f_favail` equal to `f_ffree`, `f_fsid` 0, `ST_RDONLY` and `ST_NOSUID` only). Differences: `f_namemax` is the `statfs` value, not `fpathconf(_PC_NAME_MAX)`; negative `f_bavail` and `f_ffree` wrap to unsigned without `EOVERFLOW`, as the same-width copy in FreeBSD does; inode counts are 0 on Windows, inherited from `_fstatfs`; a null output returns `EFAULT` after the descriptor is validated, where FreeBSD would fault. Layout and conversion are unverified against the PS5 library (PS5MC imports `fstatvfs` but was not run)
