The SCE name moves from a libkernel_sys stub to libkernel. Kinds
MutexType::ErrorCheck (1) to MutexType::Adaptive (4) are the mutex
types FreeBSD 11 libthr's pthread_mutexattr_setkind_np stores, and are
set through scePthreadMutexattrSettype, which maps the same values onto
those types. Other kinds and a null or uninitialized attribute throw, as
their console answer is not known.
guest_kernel_sys_pthread_np_kind round-trips kinds 2, 3, 4 and 1
through pthread_mutexattr_gettype, checks that kind 1 makes a second
lock return EDEADLK and kind 2 lets it succeed, and checks the throws
for kinds 0, 5 and -1 (the type unchanged) and for a destroyed or null
attribute.
The POSIX name moves from a libkernel_sys stub to libkernel and stores the
type through its SCE twin scePthreadRwlockattrSettype, converting the
result as the other POSIX rwlock calls do.
guest_kernel_sys_pthread_np_rwlockattr checks types 0, 1 and 2 through
both names, a rwlock built from the attribute, and the throws for a
destroyed or null attribute.
Nothing runs in VR2D without a headset, so sceHmdInternalIsGameVr2d,
IsMiniAppVr2d, IsCommonDlgVr2d and IsCommonDlgMiniAppVr2d return false,
the answer the console gives to the same four queries in libSceHmd2.
sceHmdOpen never issues a handle without a headset, so the distortion
correction, wide-near correction and 2D VR command queries, and their
sceHmdDistortion* export aliases, answer as the other handle queries:
NOT_INITIALIZED before sceHmdInitialize and HANDLE_INVALID after it,
leaving the command buffer unwritten.
A fourth title reached the refusal on another GPU and OS (reported on the
PR), so the entry no longer names a count.

A private collect read from the allocation map makes no query, so it
can't see memory that code bypassing WindowsMappings changed inside a
recorded allocation. A page decommitted in place there is the case it
can't catch: GetWriteWatch still succeeds over it, so the collect
reports no writes where a query would have refused the range.
With APS5_VERIFY_DIRECT_COLLECT set, each such collect also queries its
span's regions, and Collect throws, naming the span and the switch, when
GetWriteWatch succeeded over memory that is no longer committed
private. ENVIRONMENT.md lists the switch.
windows_write_watch_verify_direct (the same test binary with
--verify-direct, the switch set) collects a recorded private allocation,
checks its write is still reported, decommits one page in place and
requires the next collect not to succeed. Without the check the collect
succeeds.

sceNpTssCreateNpTitleCtxA creates a context like sceNpTusCreateNpTitleCtxA,
and sceNpTssCreateNpTitleCtx checks its NpId and service label first, as
shadPS4 does; both share the TUS table, its 32-context limit and its
requests.
A handler's blocks are now holds kept apart from the mask sigprocmask sets, and released when the handler returns, so a sigprocmask(SIG_BLOCK) from another thread meanwhile survives even for a signal in the handler's sa_mask. sigprocmask reports the holds; SIG_UNBLOCK of a held signal releases its hold and SIG_SETMASK, which longjmp uses, releases them all, while sigsuspend's own restore keeps them.
