seeddsandb1tdr3amer24 99d0aae38f Keep bindless reads through mixed handle phis; read misaligned buffer textures through an aligned copy (#168 )

Two general causes of FINAL FANTASY RESONANCE's missing fires, smoke and muzzle
flashes, found and first fixed by b1tdr3amer24 (GitHub issue #168).

- Translator (vendored BindlessElimination.cs, TryTableHandle): a texture read
  whose handle phi mixes c2 handle words with values that are not handles
  (undefined, or float values the compiler kept in the register on paths where
  the predicated read does not run) was removed and its result set to 0:
  58,122 reads in FINAL FANTASY RESONANCE, mostly Niagara particle vertex
  factories, whose meshes collapsed to a point. The read now takes the c2
  handle among the inputs, or reads each candidate and picks by the phi's run-
  time value; candidates read elsewhere as another texture shape are left out
  (a second sweep, ResourceManager.GetTextureTypes). Only phis that
  GenerateBindlessAccess refuses come here, so tex_dyn_slots arrays keep their
  path: the other 69,449 shaders' SPIR-V is unchanged. Several candidates are
  never used for an image store or atomic. dmsh_xlate's Log now reaches the
  notes as "translator: ..." and the build summary counts those apart.
- Host (nvn_mtl.m, tbuf_shadow): a texture buffer view at an offset that is
  not 16-byte aligned reads from the boundary below on an M4 Pro (t_tbuf_align:
  56 of 56 views wrong; the M6 measurement in the old comment does not hold).
  Such views are read through a per-submission aligned copy; aligned views are
  untouched. A workaround for the Metal limit, its gaps (GPU writes in the same
  submission, CPU_NO_ACCESS pools, image writes) recorded as open.

Translator rebuilt; lock and chain header updated. Checked: all FFR shaders
translated before and after; FFR on the Mac (fires and smoke column render,
steady; with the copy off they flicker); gfx, chain and docs tests.

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

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.
