seeddsandv0lumehi 60625182c4 Harden GPU fence wake and pass scheduling (#158 , #213 )

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.

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)

rewriter.md

Function-matched cuts: same-name rules are one patch's implementations; Taiko Risshiden V DX's frame-limiter cut reaches the base game and later builds. nso_match.resolve groups rules by name: exactly one implementation must match (the log names it), a red line only when none or more than one does. Before, each implementation of a changed function logged a red line on every build it did not fit. Taiko's MATCH_CUTS has two implementations of the frame end under one name: 1.1.1's (main+0x443e8c, 364 bytes, cut at +288) and the base game's (v0 main 47d7baf6..., main+0x43e140, 172 bytes: 1.1.1 added the frame-skip branch; the same 20 bytes at +104 = main+0x43e1a8). In v0 N is likewise a global (GOT 0xa1be28, data 0x9ec55c, 1) set to 2 only by CPrivateBattleWindow / CPrivateBattleTutorialWindow, and the start tick is read after the update; nso_fnmap.py finds no exact match for 1.1.1's function in v0, found by disassembly. Checked through patch_nso.py: v0 main takes the cut at 0x43e1a8 (implementation 2, no red line); a 1.1.1 main copy with another build ID takes implementation 1, output byte-identical to the registered cut; 1.1.1 keeps its exact CUTS. A scan of the 42 distinct mains on the drives found this limiter only in Taiko. The base game has not been run. Docs: rewriter.md (same-name implementations, procedure step 2, Found on), the game note. Checked: test_nso_match.py (new test fails on the old matcher), all 19 tool test files, docs tests

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

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.
