SET_PREDICATION threw, and packets with the predicate header bit were
rejected. The executor now keeps the queue's predication: operations 3
and 4 read a 64- or 32-bit value and bit 8 selects whether predicated
packets run when it is non-zero or zero; operation 0 clears it. Before
a predicated packet runs while predication is active, queued labels are
recorded and the value is read, as for COND_EXEC; the packet is skipped
when the predicate fails.
Indirect buffers are inlined when a submission is copied, so a
predicated INDIRECT_BUFFER call keeps its header in front of the
inlined commands and records their end like a COND_EXEC range; the
block runs or is skipped on one evaluation, as on the command
processor. Query predication, a predicated COND_EXEC, predicated chains
and flips inside predicated command buffers throw.

clamp (and omod, ignored while f16 denormals are enabled) were refused or
dropped per op: v_{add,sub,subrev,mul,min,max}_f16, v_ldexp_f16,
v_frexp_mant_f16, v_cvt_norm_{i,u}16_f16, v_{max3,min3,med3,div_fixup}_f16.
They now share one clamp on the f16 bits (clampF16Bits).

The DQbtGaBKlaw import was a throwing stub (libcCyberUnknown17). It is
the NID of "strnlen_s", which C11 K.3.7.4.4 defines as strnlen that
returns 0 for a null pointer.
The removed stub comment from #358 described its call site as
float -> float, which contradicts the hash-verified name; #492 left the
stub untouched for that reason.
Guest modules a title opens with sceKernelLoadStartModule are looked up
through their own handle, so several modules may export the same name:
every Wwise plugin exports g_pAKPluginList. On Linux a duplicate now
fails only when the executable or a guest module imports it, as the
provider would be ambiguous. Windows keeps rejecting duplicates.

The device constructor printed "Vulkan features tessellationAvailable"
before it read VkPhysicalDeviceFeatures and set tessellationShader, so
the line reported 0 on every GPU, including ones that enable the
feature. The rect-list and tessellation paths already read the enabled
value; only the diagnostic was wrong, and it suggested that
tessellation was unavailable.
Print the line right after the feature is enabled. The mesh, depth
clip and unrestricted depth range values it also reports are set
earlier and do not change.

The NID patcher rebuilds .dynstr keeping only the DT_NEEDED and
DT_SONAME strings, so DT_RUNPATH kept a stale offset and the patched
libraries shipped with an empty runpath. A library could then load only
those sibling prx that the executable already loads itself:
libSceVideoOut.prx needs libSceKeyboard.prx, which a title that does
not import libSceKeyboard never loads, so it fails at startup.
The patcher now keeps DT_RPATH and DT_RUNPATH strings, and the prx
libraries are linked with a $ORIGIN runpath instead of the build
directory, so they find each other wherever they are copied.

A title passes a work memory block and app type 0x20000000, and turns
voice chat off when initialization fails. Initialization now records
the library as initialized and succeeds. A null or empty memory block,
another app type and a second initialization throw, as their error
codes are unknown.
