The Windows crash report reads APS5_CRASH_STACK_BYTES through
EnvironmentNumber, which env_reference did not recognize, so the name had
no row in docs/dev/ENVIRONMENT.md and neither the reference check nor the
conventions check reported it. Recognize the reader as an integer reader
and add the row.
The Dinkumware std::filesystem in titles calls twelve low-level helpers
that libSceLibcInternal exports and this project did not: _Stat, _Lstat,
_File_size, _Last_write_time, _Make_dir, _Remove_dir, _Unlink, _Chmod,
_Current_get, _Open_dir, _Read_dir and _Close_dir. They now follow the
PS5 12.00 module on top of the guest stat, mkdir, rmdir, unlink, chmod,
getcwd and directory calls, with its results: file_type codes from the
mode, not_found for ENOENT, ENOTDIR, EINVAL and ENAMETOOLONG, mkdir's
1/0/-errno, -1 for a failed size, and directory reads that skip the dot
entries and report the type as unknown. As on the console, _Lstat
follows links like _Stat.
The two _Xfilesystem_error overloads are exported and still throw, as
the guest filesystem_error type is not provided yet.

A draw with DB_RENDER_CONTROL.DEPTH_COPY copies one sample of the
Z_32_FLOAT depth surface into color target 0. It now runs as a compute
pass that fetches that sample and stores it into the R32 float target,
when the draw covers the whole surface without depth or stencil tests.
With COPY_CENTROID the sample is the first one the draw covers, which is
sample 0 under the full sample mask the driver requires, as radeonsi
programs its per-sample DB to CB copies.

Nine of the twenty-one exports implement the no-device path: the lifecycle
pair accepts every call and keeps no state, the device queries answer the
empty list, the not-exists 0 and the device-not-found error, the map
requests answer device-not-found with their outputs untouched, and the
getdents family answers device-not-found on open and not-supported with
zero bytes on the read of a never-opened descriptor. The argument
validation of the register, unregister, unmap and getdents-close exports
is implemented and answers 0x80f40002; past it they keep their markers,
because no reference establishes their success path. The device-info
record and two prototypes follow SharpProspero, the rest shadPS4, each
pinned in the debt entry.
The libSceLibcInternal of a payload process on a PS5 (firmware 12.70) seeds
the additive feedback generator with a good_rand that reads its argument as an
int32, turns 0 into 123459876 and applies x = 16807 * (x % 127773) - 2836 * (x / 127773),
adding 0x7fffffff to a negative result. Its default state is the state after
srandom(1), not a precomputed table.
Replace the good_rand, build the default state by seeding it with 1 and add a
guest test that pins the first values of a fresh process, the values after each
measured seed and the saved state words of every measured initstate size.
PA_SU_SC_MODE_CNTL with POLY_MODE set to a point or line type was refused,
and every triangle was drawn filled. The state decode now takes the polygon
type of the faces that are not culled into State::polygonMode, ignores the
types when POLY_MODE is clear or the primitives are points or lines, and
keeps refusing front and back types that differ while both faces are drawn.
Points are drawn one pixel wide (PA_SU_POINT_SIZE 0x00080008 inside
PA_SU_POINT_MINMAX), the size VK_KHR_maintenance5 gives a point whose
shader does not write PointSize, and lines one pixel wide (PA_SU_LINE_CNTL).
The device enables fillModeNonSolid and maintenance5 when they are
available. The polygon mode joins the pipeline, library and draw keys and
the pipeline journal (format 5).

A store to the trimmed tail of a written buffer would be dropped instead
of failing as an alias of the render target, so only read-only buffers,
such as per-attribute vertex fetches, are trimmed.

shadPS4 declares sceNpSetGamePresenceOnline(req_id, online_id, presence)
and returns INVALID_ARGUMENT for request id 0 or a null online id. The
export took (user id, timeout), so a caller's arguments landed in the
wrong registers.
