lstat of a Windows symbolic link threw, although symlink creates links
with relative targets on Windows and readlink reads them. Report such a
link as S_IFLNK with its own identity and times and the length of its
target as st_size, through the reparse reader readlink already used,
now shared from libkernel. Links with absolute targets, junctions and
other reparse points still throw, as for readlink.
The trace summary line keeps `trace_dropped` as before: true when any
thread lost a slice, any thread's totals table was full, or the gpu
track was full. When it is true, the line now also carries
`trace_dropped_threads`, one entry per affected thread name, so the reader
can tell which thread lost data and how much. Threads that share a
name, such as the shader prepare threads, share one entry: losses are
summed, the earliest fill is kept and totals_full is true if any is.
Each entry has `events_full_after_s`, the seconds from the first
present of the window to the start of the first lost slice. It is
absent for `gpu` and in every summary line (windowed frames/seconds
and APS5_TRACE_SUMMARY_EVERY) whenever the first lost slice starts
outside the line's span of presents, including a slice whose scope
began before the window opened or one lost after the last present.
`events_lost` is the number of slices not recorded and is absent when
0; in interval lines it counts the buffer's losses since it started.
`totals_full` is true when the thread's totals table overflowed, which
makes the summary numbers incomplete; a thread with only `events_lost`
has complete totals.
The Chrome trace gets a `trace buffer full` instant event on a thread
at the point where its buffer filled.
BUILD.md documents the new fields and the event.
`trace_dropped` is unchanged, and when nothing drops the default output
is byte-identical to before.

PPSA09030's Media/Plugins/psvr2.prx imports sceHmd2ReprojectionGetStatus
from libSceHmd2 and sceVrTracker2GetCoordinateSystem and
sceVrTracker2GetPlayAreaBoundaryGeometry from libSceVrTracker2, so the
title does not start with the plugin loaded (discussion #4680). Declare
the three as throwing exports, like the earlier PS VR2 imports of
PPSA29866. The names resolve from the NIDs 8GkaY2B7opM, Y-3JCiU9bbU
and SCph4ZbkqzU with tools/nid_names.py; no reference gives their
signatures.

Guest descriptors are host C runtime descriptors. Closing descriptor 0, 1
or 2 closed the host process's standard stream, and the runtime then gave
that number to the next file opened anywhere in the process, including
files libkernel opens itself, such as the APR reader's. The title's next
close of the same number closed that file mid-read.
close and sceKernelClose now fail with EBADF for descriptors 0 to 2 that
were open when libkernel loaded, and leave them open. A standard
descriptor that was not open at load can still be opened and closed by
the guest.
PPSA21703 calls sceKernelClose(0) repeatedly while loading asset
bundles, which made APR reads return 0 or a part of the requested bytes
and raised UCRT invalid parameter reports from close.

An index at or beyond the rack's voice count returned through
APS5_INVALID_ARG_EX, which throws and ends the process. Heretic + Hexen
(PPSA26525) creates a one-voice reverb rack, takes voice 0 and asks for
voice 1 at start-up, so it stopped at 1.5 s on
"sceNgs2RackGetVoiceHandle: invalid argument". Return 0x804A8305 and
leave the output handle untouched, after the existing null-output and
rack-handle checks. The value follows prosper's analysis of
libSceNgs2.native.sprx; shadPS4 lists 0x804A0302 for the PS4 library.
Neither is a PS5 measurement, recorded in the technical debt.
ngs2_voiceindex creates one-voice sampler, submixer, mastering and
reverb racks and a default sampler rack, and checks the error, the
untouched output, the null-output and invalid-rack codes and that the
last valid index still resolves afterwards. It aborts on main's library
with the throw above and passes with this change.
sceSslEnableVerifyOption, sceSslDisableVerifyOption, sceSslSetMinSslVersion,
sceSslSetAlpn and sceSslGetAlpnSelected kept throwing because their
signatures were unknown. SharpProspero, the source already used for the
other connection functions, declares them; the signatures follow it.
The options, minimum version and ALPN list are recorded on the connection
like the verification callback; nothing reads them until sceSslConnect has
a transport. sceSslGetAlpnSelected returns null because no handshake
completes. Unknown connections and terminated contexts throw.
The PPSA07411 functional debt entry moves to libSceJson2.md, now its first
linked library.

sceCoredumpGetThreadContextInfo takes (void* threadContextInfo,
size_t threadContextInfoSize) as in Orbital's IDA type database, and the
144-byte block of 18 64-bit registers follows SharpProspero. It answers
as sceCoredumpGetStopInfoCpu: the handler is never invoked here, so an
aligned 144-byte request returns NOT_IN_COREDUMP_HANDLER without reading
or writing the block, and null, unaligned or wrapping buffers and other
sizes throw, as the console validation order is unverified.

Plan runtime-indexed T# and S# columns read through a 64-bit pointer.
Preserve the console offset alignment, signed immediate and key bounds.
Track the descriptor dwords consumed by each table in its invocation.
Reject table reads when a writable buffer or storage image overlaps them.
Cover the overlapping-storage fault and isolated second-table behavior.
Materialize runtime-indexed image and sampler records into descriptor
tables while keeping descriptor selection in the shader. Report invalid
active entries through the existing deferred fault buffer.
Bind fragment tables in the fragment set when pipeline libraries split it,
and reserve a physical descriptor for empty tables. Reject unsupported
sampler, border, cube and anisotropic pairings per entry. Keep one column
per heap access shape, one T# shared by several image operations included
(milescoviello's #5550 case), and narrow it to the union of its keys'
domains when every key has one (SleglJan's key-domain changes). Plan
columns read at (key << n) & mask over their whole domain (tibzejoker's
fix). Read records in runs through SleglJan's bulk reader, and reject
entries whose surface has no mapped byte, as Tamalero proposed. Store
table columns in disk plans; update the runtime ABI and disk format. Bound
table-sized entries in the resource cache (65,536 table elements) and the
dispatch cache (256 MiB of captured words), evicting LRU.
Morrowind imports rtprio_thread, pthread_setconcurrency and pthread_getconcurrency and stops at start-up. Report every guest thread as normal priority and accept a set without applying it; store the concurrency level as a hint. Recorded in the libkernel debt.
The EUC-JP profile threw on every two-byte character. It now maps the rows
0xA1-0xFE through a 94x94 table taken from Microsoft code page 932 (JIS X 0208
plus NEC row 13 and the NEC-selected IBM rows), and encodes a code point to its
lowest cell. Unassigned cells answer UNASSIGNED_CODE, a bad trail byte
INVALID_ENCODE, and a cut pair SRC_BUFFER_END. Three-byte JIS X 0212 characters
still throw.
