* fix(kernel): implement APR ResolveFilepathsWithPrefixToIdsAndFileSizes
Resource streamers resolve relative paths against a shared prefix; without
this HLE every call returned NOT_FOUND and assets never got real ids/sizes.
* fix(remoteplay): stub Initialize and GetConnectionStatus as disconnected
Titles probe Remote Play during pad/network bring-up; unresolved imports
returned NOT_FOUND. Report initialized + disconnected so callers take the
normal offline path.
* fix(agc): accept Gen5 hull shaders that omit PGM_LO/HI in CreateShader
Type-5 headers can start with RSRC1/RSRC2; rejecting them left null handles
and Main Thread AVs. Scan the SH table and skip PGM patch when absent.

* fix(kernel): reject getdents on file fds and emit . / .. for empty dirs
Returning rax=0 for non-directory or empty listings looked like EOF and
let GTA treat the fd as a pointer (fiWriteAsyncDataWorker AV at 0xB1).
* fix(hle): enable GuestImageWriteTracker CPU sync on Windows
Windows previously hard-disabled the tracker, so CPU-written guest
planes never marked dirty and host textures stayed empty. Arm pages
with VirtualProtect, handle write AVs in VEH, and warm/test on
VirtualAlloc memory so protect cannot poison the CRT heap.
* fix(agc): skip CB metadata draws for EliminateFastClear/Fmask/DCC
CB_COLOR_CONTROL modes 2/5/6 are colour-buffer metadata ops; applying
the bound shader as a normal colour draw corrupts subsequent composites.
Decode MODE from bits [6:4] and return before translate.
* fix(agc): merge Prospero attrib-table formats onto IR vertex inputs
IR-discovered BufferLoadFormat often keeps a stale float sharp format;
patch DataFormat/offset from the AGC attrib table (semantic index),
allow offen fetches, and map quirks 113/121 through NarrowVk for host
vertex input.
* fix(audio): harden AudioOut2 stack out-buffer writes against canary smash
Titles that stack-allocate AudioOut2 outs next to the frame canary were
corrupted by oversized or mistyped HLE writes; keep ContextPush pacing.
* Revert "fix(memory): reserve only large regions (#608)"
This reverts commit 8f9456229a.
* fix(gpu): decode Gen5 R16 and RG32 render-target formats
* fix(audio): AudioOut2 host beds, deeper waveOut queue, AJM MP3
GTA V Enhanced routes intro/menu audio through AudioOut2 and FMOD's AJM
MP3 path. Wire PortCreate/PortSetAttributes/ContextPush to dual host
stereo streams, deepen WinMM queue to 128KiB, and decode AJM codec 0
with a stateful NLayer helper so menu music is not silent.
* fix(agc): map PS interpolants via SPI_PS_INPUT_CNTL semantics
Identity ATTR→param wiring ignored hardware remapping, so UI draws
got wrong (or empty) interpolants. Pack CNTL from matched PS/GS
semantics, thread it into Vulkan/Metal as Location/Flat, and fingerprint
it in the graphics shader cache key.
* fix(agc): rect-list/NGG strips, Index8 expand, and GE_INDX_OFFSET
NGG single-rect UI needs triangle-strip expansion; Prospero Index8 must
expand to host u16; glyphs need base vertex from GE_INDX_OFFSET. Skip
param-less rect-lists instead of inventing colour draws.
* fix(np): report GTA Story Mode addcont entitlements as owned
NpEntitlementAccess was returning an empty add-on list, so GTA V Enhanced offered Buy Story Mode. Publish the installed license labels and stub premium-event registration so offline sessions take the owned path.
* fix(cpu): prefer native workers for all guest entry stubs
Route thread entry, continuation, and main entry through RunGuestEntryStub so guest stubs are not invoked above CLR-managed frames (UnmanagedCallersOnly FailFast). Keep requireNativeWorker for tbb_thead; other paths prefer workers with calli fallback.
* fix(agc): implement Rewind/Jump writers and IT_REWIND waits
GTA Subrender AVs came from AcbJumpGetSize / DcbRewind returning NOT_FOUND as packet sizes. Add IT_REWIND and INDIRECT_BUFFER writers, patch SetRewindState into the GPU wait registry, and nest-parse 4-dword jumps.
* fix(gpu): use AddrLib ExactXor for Gen5 Standard256B (mode 1)
Mode 5 already had Standard4K ExactXor; mode 1 still used the generic StandardSwizzle block table, which mis-detiles Gen5 UI atlases.
* Revert "fix(cpu): prefer native workers for all guest entry stubs"
This reverts commit 31c4db0d3886dbc51cc6cbc1a4a5432d678ab113.
* fix(memory): commit-first large maps; reserve only on failure
Replace the #608 always-reserve-only exact-map path with allocate-first and lazy reserve fallback when a huge non-exec commit cannot be satisfied. Prime and widen GetPointer commit so the fallback path is safer for native walkers. Drops the need for a hard #608 revert.
* [Agc] Implement fused shader half exports
* fix(agc): accept optional hull state in CreatePrimState
Port the CreatePrimState hull-optional path from #583 so fused HS pipelines (GTA) are not rejected with INVALID_ARGUMENT. Geometry-derived CX/UC writes are unchanged; hull is traced only.
* fix(videoout): restore thread-safe VulkanHostBufferPool (#564)
The 6db095e wipe dropped CasualcoderDev's lock-ordering-safe pool. Concurrent Return/TryTake without the gate races after the first present and can hang the submit path.
* Revert "fix(agc): implement Rewind/Jump writers and IT_REWIND waits"
This reverts commit bec77bf083dd4037455721e6874023bd05fbdb79.
* test(memory): align lazy-commit expectations with commit-first policy
Fake hosts must reject Allocate so reserve-only paths still run, and GetPointer asserts the 32 MiB prime range including AlignUp spill.
* diag(gpu): log guest-queue backlog breakdown under backpressure
Rate-limit top work types and ordered debugName prefixes when the Vulkan guest work queue stalls, so North Yankton logs show acquire/label vs draw traffic instead of only VulkanOrderedGuestAction.
* perf(agc): coalesce acquire flushes and batch non-DMA label wakes
Flush pending ACQUIRE_MEM invalidation at draw/dispatch/dma/flip boundaries instead of before every packet, and complete release/write-data producers in the same ordered action so load paths enqueue far fewer VulkanOrderedGuestAction items.
* perf(gpu): wait for ordered-action fences and keep draining sync
On Windows/Linux, block briefly for queue-visibility fences instead of deferring the whole logical queue for the tick. Prefer ordered sync/flip heads under backlog pressure, and keep macOS non-blocking defer behavior.
* perf(gpu): raise sync-item ceiling above payload guest-work cap
Apply SHARPEMU_PENDING_GUEST_WORK_ITEMS mainly to compute/draw/image payload work, and allow a higher SHARPEMU_PENDING_GUEST_SYNC_ITEMS ceiling for zero-payload ordered actions and flip markers. Keep the byte budget as the RAM safety valve.
* fix(gta): stub Voice ports and implement sceKernelCheckReachability
Resolve North Yankton-path Voice Create/Delete/Connect/Disconnect/End NIDs and EnumerationThread reachability checks so leftover unresolved imports are not on the critical path.
* diag(gta): arm flip/present/wait probes after North Audio
Rate-limited load_progress TRACE for flip submit, ordered flip enqueue, present taken/not-taken, and GPU wait backlog so North Yankton freezes can be classified without full AGC tracing.
* fix(ampr): restore sequential offset=-1 reads for streamer packs
Re-wire PakDirectoryTracker into sceAmprAprCommandBufferReadFile (dropped in #216) so RAGE sequential pack reads no longer fail while the North Yankton UI keeps flipping. Also rate-limit CheckReachability miss paths for EnumerationThread diagnosis.
* fix(hle/videoout): Windows GuestImage opt-in and keep GTA intro without sync
Default the tracker off on Windows to avoid VirtualProtect thrash, gate AGC
texel-copy skips on Enabled so guest Bink planes keep shipping pixels, and
drain CPU-written images on the present thread when sync is opted in.
* fix(videoout): probe guest content when tracker off so UI can skip copies
Restores upload-known/texture-cache skips for Dead Cells menus, and uses a
sparse guest-memory fingerprint when GuestImageWriteTracker is disabled so
CPU-updated Bink planes still force texel copies for GTA intro.
* fix(audio): keep 128KiB host queue AudioOut2-only
Restore the default 32 KiB (~171 ms) PCM bed for classic AudioOut so
titles like Dreaming Sarah stay in sync; only AudioOut2 opens the deeper
queue needed for bursty FMOD Push on GTA.

* Kernel FS: default-deny unmapped guest paths (fixes absolute-path host escape)
ResolveGuestPath returned any unrecognized guest path verbatim as the host
path. Because absolute paths ("/etc/passwd", "C:\Windows\...") are already
fully qualified, they skipped the relative-path app0 fallback and were handed
straight to FileStream/File.Delete/etc., giving a malicious game arbitrary
host-file read/write/delete outside the sandbox.
Return string.Empty (deny) on fallthrough instead. Most callers already treat
a nonexistent host path as NOT_FOUND; open/truncate/rename get an explicit
empty-path guard so a denied path can't reach FileStream and throw an
ArgumentException their catch blocks don't cover.

* Kernel FS: contain built-in mounts (fixes Windows drive-letter injection)
The built-in mount branches (app0/temp0/download0/hostapp/devlog) combined
the mount-relative guest path onto the host root without re-checking
containment. NormalizeMountRelativePath clamps ./.. but splits only on
separators, so a drive-qualified token like "C:" survives as a segment and
Path.Combine then discards the mount root, yielding a raw host path such as
"C:\Windows\..." (arbitrary host read/write).
Route every built-in branch through a new CombineWithinMount helper that
re-resolves with Path.GetFullPath and verifies the result stays under the
mount root -- the same guard TryResolveRegisteredGuestMount already applied.
Denied paths return string.Empty, which callers treat as unresolved.
AprStreamingContractTests passed a raw Path.GetTempFileName() as the guest
path, relying on the now-removed absolute-path passthrough; updated it to
address the file through a registered mount.

* Kernel FS: reject reparse points inside mounts (fixes symlink escape)
Lexical containment (Path.GetFullPath + StartsWith) proves the textual
path stays under the mount root but does not follow symlinks/junctions.
A malicious game dump could plant a reparse point inside app0/temp0/etc.
pointing outside it, so a contained-looking path resolved onto the host
filesystem. Walk each existing component from the mount root to the
candidate and refuse any reparse point, in both the built-in and
registered-mount resolution paths. Mirrors AvPlayer's existing defense.

* Kernel FS: fail closed when path containment cannot be verified
The reparse-point and drive-letter containment guards call Path.GetFullPath
and File.GetAttributes on untrusted guest paths. Both throw on crafted
over-long or invalid-char input, and ResolveGuestPath runs outside the file
syscalls' try blocks, so such a path was a guest-triggerable crash rather
than a denial.
Wrap the GetFullPath calls in CombineWithinMount and the registered-mount
path, and widen the GetAttributes catch, to treat any access/format failure
as an escape (deny) instead of propagating. Also tighten the ".." fallback
check so a legitimate file named "..foo" is not falsely rejected, and hoist
the repeated Path.GetFullPath(mountRoot) into a local.
Adds a regression test asserting the resolver returns without throwing for
an over-long and a NUL-embedded path under a mount.

* Kernel FS: assert malformed paths resolve to empty, not just no-throw
The fail-closed regression test asserted only Assert.NotNull, which a
non-nullable string return can never violate via its value (only a throw,
which aborts the test earlier anyway). Tighten to Assert.Equal(string.Empty)
so it also locks in fail-CLOSED: a regression where a malformed path resolved
to a non-empty host path would now be caught.

* Kernel FS: route new AMPR batch tests through a registered mount
Merging main brought in three AprStreamingContractTests that pass raw
Path.GetTempFileName()/temp host paths as guest paths. The default-deny
resolver from this branch rejects absolute host paths, so MissingMidBatch
failed at index 0 instead of the intended index 1. Address the present
file through a registered mount (as ResolveStatAndReadFile already does)
so entries 0 and 2 resolve and the batch fails at the genuinely-missing
entry. The two all-missing tests were unaffected but share the fix's intent.

* Kernel FS: make a matched-mount denial terminal; fix Unix-only test asserts
A registered mount that claims a path by prefix but denies it (failed
containment or a reparse point inside the mount) now short-circuits in
ResolveGuestPath instead of falling through to the built-in mount branches.
The fall-through let an overlapping prefix (a registered "/app0" vs the
built-in SHARPEMU_APP0_DIR branch, which resolves against a cached root)
re-resolve a denied path and turn the denial back into a resolution -- the
reparse-point escape reappeared on Linux CI through exactly this path.
Also fix two tests that asserted Windows-specific behavior unconditionally:
a "C:\..." path is not absolute on Unix (it resolves contained under the
mount there), and that case is now pinned to Windows only.
