The title's sce_sys/trophy2/trophyNN.ucp is read on first use with a
bounds-checked .ucp reader and a small JSON reader. tropconf.json gives
each trophy's grade, group, hidden and reward flags, platinum and
unlock condition, and tropmeta_<tag>.json its texts in the console
language, then en-US, then the file's default language. Contexts
remember their user and service label, so the queries find the file.
The trophy, group and game queries report these names, grades, groups
and counts, list every trophy and group, and give progressive trophies
their target. Unlocks are not recorded yet, so every trophy reports as
locked and nothing is written to the host. A missing file is ignored
and a malformed one is logged once; either way the queries keep their
placeholders. A JSON document that nests deeper than 64 levels or holds
more than 1048576 values counts as malformed, which keeps the parsed
values to about 140 MiB.
A progress value is {int32 type, 4 reserved bytes, uint64 value}, as
KytyPS5 lays it out, which makes the trophy details 1312 bytes and the
trophy data 32 bytes. Size checks for every query structure keep the
layout fixed, and the technical debt names its single public source.
On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_condattr_setpshared accepts only 0 and leaves the attribute
unchanged otherwise. pthread_condattr_getpshared reports 0 and returns
EINVAL for a null, uninitialized or destroyed attribute, also with a
null output. With an initialized attribute a null output crashes the
console; here it throws.

Measured on a PS5 (firmware 12.70): the getter reports 0, and of the
values 0, 1, 2 and -1 the setter accepts only 0 and checks the value
before the attribute. A null or uninitialized attribute, or a null
output, crashes the console; here it throws.

On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1,
pthread_spin_init, pthread_barrierattr_setpshared and
pthread_mutexattr_setpshared accept only PTHREAD_PROCESS_PRIVATE (0);
1, 2 and -1 return EINVAL and leave the attribute unchanged.

Shader registration and the shader ABI resolves run on the title's own
threads, which never bound a trace buffer, so their Shader.Register and
Shader.Resolve* scopes were missing from every trace and summary. Those
entry points now bind the calling thread as `title` with the 32,768-event
buffer the shader preparation threads use.

Color format 7 (COLOR_11_11_10, float) keeps its 10-bit component in the
low bits; with the reversed component order (COMP_SWAP 2) that is blue,
with red in the high 11 bits. Vulkan has no such layout, so the target was
refused at decode.
Render it the way 10_11_11 unorm targets are rendered: an R32_UINT
attachment, the reversed export mapping 0xc6, and a new
ColorExportPacking::Float11_11_10 that makes the pixel shader pack each
export with the format-43 image store conversion (toward zero, overflow to
the largest finite value, negatives to zero, NaN kept). Blending, partial
writes, 16-bit integer exports, DCC and the other component orders throw.

An ITIMER_REAL or alarm expiry while SIGALRM is blocked is marked on the
pending set of sigtimedwait instead of throwing, as kern_psignal leaves a
blocked signal pending. sigwait, sigwaitinfo and sigtimedwait take it,
repeated expiries merge into one pending signal, and unblocking it runs a
guest handler on the unblocking thread or, with the default disposition,
exits the process with status 142 as FreeBSD's default action does.
The expiry rechecks the mask after marking the signal, so an unblock that
races it does not leave SIGALRM pending while unblocked, and TakePending
clears the bit with the value it read so one signal is taken once.
