sceNpRegisterStateCallback and sceNpRegisterStateCallbackA stored nothing,
the unregister calls always succeeded and sceNpCheckCallback did nothing,
so a title that waits for its NP state callback never learned the user's
state. #1277 reports that Minecraft Preview (PPSA19639) needs the callback
(stop 2).
sceNpRegisterStateCallbackA now keeps up to 8 callbacks and returns the
slot plus 1. A null callback returns INVALID_ARGUMENT, a callback that is
already registered CALLBACK_ALREADY_REGISTERED and a ninth one
CALLBACK_MAX (0x8055001D). sceNpUnregisterStateCallbackA returns
INVALID_ARGUMENT for an id outside 1..8 and CALLBACK_NOT_REGISTERED for an
empty slot. The legacy sceNpRegisterStateCallback keeps one callback with
the same errors. The rules follow shadPS4
src/core/libraries/np/np_manager.cpp @15abf68c9b52 (RegisterStateCallbackA
and UnregisterStateCallbackAById L857-L901, the legacy pair L981-L1005,
ORBIS_NP_STATE_CALLBACK_MAX L36) and np_error.h L38.
Each registration is marked pending. sceNpCheckCallback takes the pending
registrations under the lock and calls them after releasing it, on the
calling thread, with SIGNED_OUT for the initial user 0x10000000. For the A
form this follows KytyPS5 src/libs/network.cpp @9e41d8320a27
(NpRegisterStateCallbackA L4021-L4034 marks the registration pending,
NpCheckCallback L3959-L3974 delivers it once). KytyPS5 never calls the
legacy callback (NpRegisterStateCallback and NpUnregisterStateCallback,
L4009-L4019, do nothing). The legacy callback is called as
(user, SIGNED_OUT, nullptr, userdata), as in shadPS4, which passes an NpId
only for SIGNED_IN (L823, L938-L940).
shadPS4 queues SIGNED_OUT from the user service login event instead
(DispatchPendingNpStateCallbacks L903-L962), and the same event calls the
reachability callback once with UNAVAILABLE (L922-L931, L959-L961). The
reachability callback is still not called here. These differences and the
unmeasured console behaviour are recorded in
docs/dev/debt/libSceNpManager.md.

On Windows every direct host import leaves the write watch, and a sampled
texture snapshot over it was compared with guest memory at every lookup:
its generation stays 0, so UnchangedSince never holds. ASTRO BOT
(PPSA21564) compared about 31 GB per 10 s at the title.
The lookup now keys such a snapshot by UntrackedHint, NewestStamp,
ForgetSerial and the recorder's newest write note, taken before the
snapshot is read or compared, as StorageTexture::compareUntracked does,
and skips the compare while the key is unchanged and no recorded work
writes the surface. The byte compare still decides after any mark.

ds_add_f32 and ds_add_rtn_f32 now follow the measured hardware: both
operands are flushed to a signed zero when bit 0 of the f32 denormal field
is clear and the result when bit 1 is clear, the sum is rounded to nearest
even, a NaN data operand is stored quieted, else a NaN old value is stored
quieted, and +inf + -inf stores 0xffc00000. Measured on gfx1010 and, in
#5492, on gfx1031.
The new MemoryInfo field is stored in the shader disk cache (field count
31, minimum record 79 bytes, FormatVersion 34). The parts that depend only
on the data operand are computed once, before the CAS loop.

Main's flatVolumeLineCompatible change also took format 34 with another layout, so entries of either would load as the other.

Move bounded vertex folding and empty-image feedback into separate topics. Keep the replay coverage proof, stage contracts, finite-reference tests and mapped cache regressions; version the stencil layout separately as format 34.

Preserve instance and triangle order with one dynamic-reference shader pipeline. Require bounded references, complete export coverage, replay-safe mask control and resources; refuse unsupported side effects and feedback.

The front-face VGPR was always +1.0 / -1.0, which is its form only while
FRONT_FACE_ALL_BITS is clear (current Mesa reads it with fgt 0 / fsign).
With the bit set, as Mesa 22.0 RADV programs it, a back face reads 0 and
a front face non-zero: ACO then tests it with v_cmp_lg_u32 0. Uncharted:
Legacy of Thieves Collection (PPSA05684) sets the bit and its two-sided
cloth shaders test v_cmp_lt_u32 0, so -1.0 (0xbf800000) made every back
face a front face: the insides of the menu skeleton's rags kept their
front normals and were lit white by the spot light behind them.
The pixel stage info now carries the bit (request version 26, cache and
draw keys), the decode reads SPI_BARYC_CNTL when FRONT_FACE is an active
input, and the translator turns the builtin into 0xffffffff / 0. The
exact front value is not measured (docs/dev/debt/shader.md).
AI-assisted: yes
On ds_ordered_count M0 holds the ordered wave ID, not a GDS address as
for ds_append: radeonsi and ACO pass the wave ID as the intrinsic's
pointer and keep the counter address in offset0. Reading M0 as the base
and size skipped the add whenever M0[15:0] was 0, so every wave got the
same range. The test now runs the ordered pass with M0 = 0 and M0 = 7.

ds_ordered_count adds the first active lane's value to a GDS counter and
returns the previous value, like ds_append adds the lane count. Waves are
not serialized in launch order: each still gets its own range. Ordered
swap and multi-dword counts stay refused. DISPATCH_DIRECT and
DISPATCH_INDIRECT accept ORDERED_APPEND_ENBL (bit 3) of the initiator.
Compute shaders of MXGP 26 (PPSA30839) use both.

A plan copied every control-flow condition with all its operands, though one
that depends on a vector register is never evaluated. Such conditions are
dropped, and the copied values live in one arena without use lists.
VGT_TF_PARAM.PARTITIONING 3 now compiles to Vulkan's fractional-even
spacing, which radeonsi programs as PART_FRAC_EVEN. Its factors are
bounded at 64 like integer partitioning; Vulkan raises the remaining
ones to at least 2, the D3D11 range for this mode.
