Use only the remaining finite timeout after the fast-event wait instead of
starting a second full wait for feedback. Preserve polling, CPU completion
ordering and the existing infinite-wait stage caps.
Add deterministic regressions against the production wait function across
all three fast-wake sites and the four fast-wake/wait-ledger combinations.

Profile 0100C1F0051B6000 (SDK 4.4.0, Retro Studios' engine, NVN): plays on the Mac from boot
through the menus and the intro cinematic into the first level at 60 fps. General changes:
- svc SetHeapSize: a request beyond the heap region returns ResultOutOfMemory, as Horizon
(the game binary-searches its heap size between 3 and 6 GB)
- shader_split.py: SNVN program records in Retro's RFRM forms (MaterialArchive.arc, the packs'
MTRL resources) and the LZSS-compressed startup material archive in main
- nvn_mtl.m: a texture in a CPU_UNCACHED pool starts with its storage at first use (title logo,
menu panels); transform feedback captures draws that rasterize too
- dmsh_build.py: transform feedback buffers holding several outputs (DK's fur simulation);
chain header regenerated
- hle_audren.c: the renderer event is the kernel event the audio service gives, not the SDK's
local one (the main thread was starved at the first level's load)
- hle_oe.c: oe::GetUserInactivityDetectionTimeExtensionMode
Profile 010057D006492000 (no virtual address memory: the 4 GB heap layout; tex_flush_upload and tex_dirty_upload for the textures Unreal writes from the CPU into uncached pools after creating them) and its note. Brought up on the Mac through the boot, the language notice, the title, the traveler selection and Ophilia's and H'aanit's openings (free play in the cathedral and in S'warkii) at 30 fps; battles, sound and the iPhone not yet tested.
General changes found on it:
- patch_nso.py: a jump table whose index is bounds-checked with a 64-bit cmp (main+0x1676f58), accepted only in the last pass so earlier rewrites are byte-identical.
- profile_guess.py: Unreal's 64 GB alias layout only with virtual address memory (this game sets a 3.08 GB heap instead).
- NVN: nvnTextureBuilderGetSparseTileLayout / nvnTextureGetSparseTileLayout (Unreal sizes a sparse texture's mip tail with it; unimplemented, it asked for 1.75 GB twice); sparse 2D textures without a packaged layout take the block height of their 64 KB tile (the world map's tiles were shuffled); every virtual pool gets an address range of its own until its first mapping decides between the alias (a whole-pool mapping, Mario's pool) and the sparse page table (Unreal's one-texture pools, mapped piece by piece: streamed textures were black and later mappings refused).
- Audio renderer: SdkMutexType is looked up only when the SDK uses it (SDK 3.5.1 takes LockMutex at +0x1f8).
README: the gallery entry (Mac screenshot of S'warkii, IPA ~3.6 GB, all 5,434 shaders built for iOS); AGENTS.md: seventy-one games.
Checked on the rebased tree: the tool tests (15 skipped), the docs tests, a Mac boot into the traveler selection; before the rebase the graphics tests (make run, exit 0).
Hoist block-linear row and slice addressing out of segment copies, and
index HLE, forced-takeover and missing-import names while retaining
existing duplicate precedence and stub identity.
Add byte-address differential tests and direct collision, duplicate,
growth and reuse checks. Correct the ASTC-tail and loader-serialization
comments and document independent CPU microbenchmarks. Keep TotK
prewarm data in a separate change.
Validation: 5,334 texture checks; symbol-index and NRO lifecycle tests;
AddressSanitizer/UBSan; documentation checks; Mac host build and changed
iOS source compilation. No new gameplay validation.

Integrate fast shared-event wakeups, per-segment publication, array-slice
pass merging, and independent compute dispatch hoisting from the PRs.
Serialize CPU completion effects before publishing completed fences and
validate recycled post records. Preserve submission order for early waits.
Guard scheduling against attachment aliases, first-draw and bindless
reads, indirect ranges, stencil writes, and explicit barriers. Add direct
Metal regression coverage and a gated CPU completion race test with TSAN.
Record final BotW and Metroid Dread gameplay validation with optimizations
on and off. BotW retains fewer render passes, but the measured 60 Hz M4
Pro runs do not establish a timing speedup. Keep the original higher-load
and iOS performance claims explicitly unverified.

Decode packaged byte 0 as separate block-height and block-depth nibbles,
including explicit zero dimensions, and size linear compressed textures
by pixel rows. Port the driver-derived rules from PR #201 and preserve
its attribution to digitalhivehub's PR #11 measurements.
Integrate the layout test with current main, correct its BC4 label, add
independently addressed CPU markers and packaged GPU mip coverage, and
record the mechanisms in the reference docs and symptom index.
Validation: 9 driver shapes, 189 CPU texture checks (also ASan/UBSan),
17 GPU deswizzle cases, 154 NVN checks, documentation checks, Mac host
build, and iOS compilation of 133 sources pass. No new gameplay or
iPhone runtime validation.

Take upload stamps before protection, initialize cached checks from those
stamps, and wait out pages another thread is unprotecting before retrying.
Publish page generations before advancing the clock again in both the fault
handler and batched host pre-write path. A shared stamp_page helper closes
the remaining batched publication race in the original PR.
Add deterministic publication regressions for both paths and document the
mechanism and the limits of the game-level evidence. The regressions fail
on main, and the batched case also fails with the original PR applied.
Validation: full graphics suite, Wonder Mac host build, all 133 iOS source
compile checks, and documentation tests pass. No fresh gameplay or iPhone
runtime validation.

Support PKZ v1 archives and advertise the translator's GPU-code range independently of SDK version. Register the 1.0.1 profile, shader tables, regression checks and Mac bring-up findings. Retain 30 fps; document the unshipped 60 fps experiment and outstanding iPhone validation.
The profile is the NSP script's provisional one with tex_flush_upload and tex_dirty_upload: RE Engine writes its UI textures (ASTC) into CPU-visible pools in place, as Monster Hunter Rise does, and without both keys the language screen's background and buttons were magenta (with tex_flush_upload alone they still were). 7,744 shaders from the PAK's SDF definitions and main; 7,739 build. The other 5 are compute shaders with atomics on a 3D image, which SPIRV-Cross indexes with an int3, as Octopath Traveler 0's 16; none was requested on the routes below. PR #138 (Nishikori-Yui) built them by flattening the coordinate in dmsh_build.py, a chain change that would rebuild every game's libraries, so it is left out until a run requests one (the game note). PR #138's profile is the same as this one (the same keys and shader tables).
Host fix: the memory line's "freed but alive" count only grew in most games (Animal Crossing: New Horizons 3,113 after 27,900 frames, Pokémon Sword 2,050, Super Smash Bros. Ultimate 1,279; Ghost Trick 125 to 146 buffers, 6.6 to 8.7 GB of zero-copy buffers, so GPU allocated read 9.9 to 11.7 GB against 2.2 GB resident). A temporary census of every host table that can hold a texture over a pool buffer found no holder: mtl_pool_del runs on the guest thread that finalizes the pool, whose implicit autorelease pool never drains, and adding the buffer to the weak table g_dead_pools left it autoreleased there. containsObject: / removeObject: on a weak NSHashTable do the same (a standalone test), and res_add / res_remove call them on guest threads too. mtl_pool_del, res_add_at and res_remove now have their own @autoreleasepool. Ghost Trick: 0 freed but alive, GPU allocated 1.7 GB instead of 8.3 GB 300 frames into the boot and 2.9 GB in Chapter 1, resident memory, frame times and pictures unchanged; Pokémon Sword: 8 to 0 at the title after 90 s, the same frame pacing.
On the Mac: the opening movies, the language screen, the first-boot notices, save creation, the Bonus Content notices and Chapter 1's opening in the junkyard (the Ghost World, the first trick), and a second boot that loads the save, at 60 fps (frame interval p99 about 17 to 19 ms), about 2.3 GB resident, no red line; the Wwise sound plays (a muted run with DM_AUDIO_DUMP). Checked: the tool tests (57, the docs check among them), t_nvn (124 checks), a boot of the rebased host. README (games gallery, a Mac picture of the junkyard), AGENTS.md's count (sixty-two: the gallery's cells), the game note, the games table, docs/reference/nvn-objects.md and the symptom index say so
