seedds 4db4c69f0b Port Donkey Kong Country: Tropical Freeze 1.0.2

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

game-state.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)

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
packing.md	NSP script, compressed inputs and build artifacts
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.
