seeddsandAleksandr Svidchenkov 796d592aa8 Test and document NVN prewarm key normalization

Exercise historical manifest rows through the production warmer, shader loader,
pipeline builders and draw-time cache. Check normal and merged passes on both
MTLDevice and Metal 4, with GPU pixels compared against the original descriptors.
The regression fails on the PR base and when the merged-pass guard is removed.

Document the shared normalization rule and keep game measurements in their notes.

audio.md

Subsystem references and a symptom index: the failure catalogue of docs/agents/03-bringup.md and the per-title material of docs/agents/04-graphics.md (section 1's container list, section 6 and its "Seen in <game>" subsections) move into docs/reference/, one heading per mechanism: rewriter.md, memory.md, threads.md, services.md, movies.md, audio.md, frame-rate.md, nvn-objects.md, rendering.md (with the Vulkan and OpenGL layers), shaders.md and game-state.md, indexed by docs/reference/README.md. Each entry gives the symptom, the cause, the fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md) and any check, caveat or later change; one mechanism met on several games is one entry. docs/agents/symptoms.md lists every entry's symptom (an assertion, a [RED] line, an abort or crash site, a visible result) with a link to it, 350 lines, generated from the Symptom bullets. 03 keeps the loop and reading the log, and its Failure catalogue section now points to the references, the index and where a new finding goes; 04 keeps sections 1-5 and 7 (the container list is shaders.md's Containers by engine), and section 6 says where each kind of finding is. Facts in the old sections about one game only were checked against that game's note, where they already were. Statements the code no longer matches are marked as history beside the current value (movie output slots: MD_NOUT 64, MD_NOUT_AAC 32, MD_NOUT_VIDEO 16; APP_POOL is the profile key app_pool; Engage's layout is 5 / 4.375 GB; inline uniform updates are deferred by default; scaled copies are drawn), and Tears of the Kingdom joins the node-area entry's build list (issue #70 ). The game notes, docs/agents/README.md, 02 and 05 link to the exact entries, and so do the comments in nvn_mtl.m (nvnTextureCompare) and hle_audio.c (the RemoteIO buffer) and the provisional-profile note in profile_guess.py. 03 goes from 29,600 to 470 words, 04 from 34,400 to 3,500. Checked: every backticked span, module address, issue / PR number and 16-digit hash of AGENTS.md, development.md, dm/games/README.md and docs/agents/01-05 at 6a06877 (4,600 items) still appears in the repository's Markdown (the same five file patterns as before appear as the full names they stood for), every relative link and heading anchor in the repository's Markdown resolves, and the tool tests pass (the four that need capstone or lz4 in the T7 venv)

OCTOPATH TRAVELER II (0100A3501946E000, update 1.1.1 = v131072, Unreal Engine 4.27 on SDK 12.3.2): game profile, inline Unreal shaders in version 11 paks, and five general host fixes. Plays on the iPhone (IPA 5.9 GB, user; that IPA predates the geometry and allocator changes below). On the Mac: the boot, the title, a new game, the traveler selection, Hikari's opening into his first battle (won) and the scene after it, and Castti's opening (the flashback, the ship, free play on the deck), at 60 fps (frame time p50 16.7 ms, p95 about 17 ms) with CRIWARE sound, about 2.8 GB resident. Shaders: the project ships no shader code archives (bShareMaterialShaderCode off), so each material's shaders are inline in its .uexp and the global ones in Engine/GlobalShaderCache-SF_GLSL_SWITCH.bin, each an entry of FShaderMapResourceCode (an LZ4 block, its raw size, its frequency): uepak.py inline_shaders sends a version 11 pak with cooked packages and no .ushaderbytecode to shader_split.py's inline reader (ue_legacy_jobs; Zlib and LZ4 pak blocks decoded in Python, Pak.read), ue_inline_shaders finds each LZ4 block by its first literals (LSLG), and profile_guess.py / the NSP script tell the two kinds apart; 13,980 shaders in 13 s. Profile: Unreal's FMallocBinned3 cut with an OBS_UE_MALLOC gate as DRAGON QUEST VII Reimagined's (GCreateMalloc main+0xbecbf0, a 20-slot vtable, hle_uemalloc.c), a 2 GB engine region (game_args) with the node-area cut on this SDK 12.3.2 build (sdk_patches.py, sdk+0x346190 / +0x34622c), fps_target 60 through t.MaxFPS / rhi.SyncInterval (hle_fpslock.c; the same route at 30 and 60 fps reaches the same scenes at the same times), pad_layout full (the battle menu picks weapons with the D-pad), a prewarm list of 843 lines. General fixes: (1) a shader may bind 96 resources instead of 64 (NVN_REFL_MAXB: the traveler selection's 3D map shader binds 66, and the map was black); (2) the parallel precompile look-ahead (pso_predict_rest) restores the scissor, which state_op keeps in R, not S: with pipelines built on demand the picture went bright green and white from Castti's flashback and Hikari's battlefield on (bisected with simultaneous runs; DM_NVN_PREDICT=0 turns the look-ahead off); (3) a geometry draw above the 256 MiB capture scratch bound is drawn in runs instead of skipped (nvn_geometry.inc geo_split: one instance at a time, then runs of at most 4,096 list primitives whose index range fits 64 MB, one read of the indices, one GPU wait), the index compaction after the geometry kernel runs as count / offset / write dispatches instead of one thread (each frame drawing Unreal's 129,032-triangle point light shadow took about 300 ms with it), and scratch arenas above 32 MB are released after 600 idle submissions (arena_new takes the smallest that fits); (4) MapMemory takes a thread stack from the host's Unreal heap (dm_ue_heap_owns: a range outside the guest block the host maps read-write, vm_region_64): with cae5ec2's stricter source check every Unreal game on the host heap aborted in MapAliasStack at nnMain (checked: this game and Pikmin 4 boot); (5) the host Makefile rebuilds on a change to dm/gfx/nvn/*.inc. Scripted input takes partly tilted sticks (L<x>/<y>): the traveler selection opens a card only while its quill cursor rests on a traveler, and full-tilt presses swept past them. Open: 2 of 87 Mac boots crashed at the title in the game's CRI cue sheet loader (main+0x1d8054, a record copied while one of its TArrays held count 1 and no data); the writer is not found yet (the game note). Checked: 57 tool tests, the gfx run list (t_geometry 95 checks) and the docs check pass; the NSP script packs the IPA from the NSPs (Mac and iOS). README (games gallery, a Mac picture of Hikari's first battle), the game note, the games table, docs/reference shaders / memory, docs/agents/04 and the symptom index say so

README.md

Subsystem references

How the host meets each part of a Switch game, and every failure met so far, one entry per mechanism: symptom, cause, fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md). Start from the symptom index when you have a log line or a visible result; the workflows that lead here are in docs/agents.

File	Covers
rewriter.md	The NSO rewriter `patch_nso.py`: jump tables, exclusive windows, patch area reach, cuts and observation gates, functions without unwind entries, stack and system registers, relocations
memory.md	Guest layout, heap and application pool, virtual address memory and the alias region (the SDK's node area), engine allocators, mapping SVCs, running out of memory
threads.md	Thread creation and cores, address arbitration, yields and spin waits, events
services.md	SDK calls and system services: sm connections, names that changed between SDKs, file system and saves, add-on content, input, keyboard and applets, display and operation mode, accounts and network, settings and fonts, C library and time, modules
movies.md	The SDK's movie library: decoder lifecycle, output slots, native-texture output, demuxers and codecs, game movie players
audio.md	The audio renderer and its command lists by SDK, AudioOut and devices, codecs, timing
frame-rate.md	The host's frame step, engine frame limiters, present intervals and display rates, CPU cost
nvn-objects.md	NVN object sizes, memory pools, command memory, queues and syncs, CPU-written textures, NVN entry points
rendering.md	The replay on Metal: textures, passes and clears, blend / depth / stencil, vertex input, uniforms and ordering, conditional rendering; the Vulkan and OpenGL layers
shaders.md	Shader containers by engine, control sections and code, translation, bindings and handles, shaders compiled at run time, pipelines and caches
game-state.md	Saves, scripted state, and game behaviour that looks like a host bug but is not

A new general finding goes into the file and section it belongs to, in the same form, with a line in the symptom index; a fact about one game goes into that game's note.
