- the grass fade is a plane across the view, not a ring around the player: `0x6b2b80` texgens the camera-space position through `T(0,0,−52.5)·Ry(π/2)·S(1/17.5)`, so the fade coordinate is view-space depth, `u = (z_eye − 52.5)/17.5` — we measured `distance(eye, fragment)`, a sphere, which meets the ground as a circle centred on the player that slides as they walk and bites a piece out of every tuft it crosses, and that was the hard border; the ramp is `0x6b2320`'s quantised 64×8 table, `alpha = 4·(63 − col)`, read bilinearly as `(254 − 256·u)/255` and capped at `252/255` — plateau to 52.64 yd, zero at 69.86 yd, near grass 98.8 % opaque and never 100 — where we had a clean 1 → 0 line; the product `tex0.a × ramp` is what the 128/255 `detailDoodadAlpha` cutout tests (both stages MODULATE, `[0xc7b2fc]`, confirmed verbatim in all four apitrace captures), so the tuft eroding out at 61.11 yd is the reference's own behaviour and the "fix" that would have removed it never landed; the pass owns its render state — blend mode 2, ALPHAREF 128, cull off, depth-write on, the per-slot draw `0x6b2d60` binding nothing but the texture — where we passed the batch's authored blend and cull through, and the `clutter_state` probe counted the cost: of 322 detail batches, 2 author Opaque (no cutout, their margin drawn as a solid card) and 5 single-sided; the build gate measures the chunk's box against the frustum corner ray derived from the live projection (≈1.31× at 16:9, ≈1.45× at 21:9), not its centre plus a 24 yd margin that popped whole chunks in on relief (2004) - a `<Model>` widget's animation state is Lua-observable and lives in the engine: a private scene clock its own `OnUpdate` advances by `trunc(elapsed·1000)` ms on visible frames only (`0x76d7f0`), an arm with an anchor the sampler re-reads every frame (`0x7121a0`), `OnUpdateModel` at the top of every paint (`0x76d1a0`) and `OnAnimFinished` from the completion callback (`0x76cdc0`); the file's sequences and bounds are facts the host hands over, `SetModel` seeds Stand now or when they land (`0x70ebd0`) with a queued arm replaying after the seed, and the XML `scale=` on a model pane is the model's scale (`CSimpleModel::LoadXML` `0x76cac0`), which the loader had never read (2007); and the pane renders its M2 — every visible pane with a file gets a cell of one render-target atlas at its device size through one orthographic camera, the root at `1280·modelScale·layoutScale` FrameXML units per model unit, the tile's `AnimationPlayer` paused and seeked to the engine's play head, the light black, particles in their own unit (`768·√(a²+1)` per model unit, neither scale), composited as one premultiplied quad at the callback rank; two corrections off the bytes: `OnUpdateModel` fires only with a model installed (`[widget+0x318] ≠ 0`) and `OnAnimFinished` fires once per arm for a looping sequence too (`0x719370`); the loader now applies a `<Model>`'s `file=` at all, which every XML-declared pane had lacked; retired: the minimap ping's byte-measured sprite, since `MiniMapPing` and `WorldMapPing` draw their own file on the pane's clock (2013) - the stance feed fires `UPDATE_SHAPESHIFT_FORMS` only for a list change: the reference fires it at `0x4b28ff`/`0x4b2e43` from learn, unlearn and rank-replace alone, while ours fired on any change of the pushed view, and every fire runs the stock `ShapeshiftBar_Update`, which shows `ShapeshiftBarMiddle` unconditionally past two forms and `Show()`s an already-shown frame — no `OnShow`, no manage pass — so a stance switch or the category-47 cooldown arming and expiring left the middle strip drawn alone over a raised bottom-left bar; castability now rides `SPELL_UPDATE_USABLE` (`0x4b31c0`), active/texture/cooldown are pushed silently and repainted on `PLAYER_AURAS_CHANGED` and `SPELL_UPDATE_COOLDOWN`, the feed ordered before both handler sets so they read the fresh list (2009); and the loot-roll frame waits for its item template (B371): `GroupLootFrame_OnShow` paints once and nothing repaints it, and we fired `START_LOOT_ROLL` on the frame the packet arrived, against a snapshot whose name, texture and quality were still `None` — the reference's `0x61b310` ends in the item-template cache lookup `0x55ba30`, a hit firing the event there and a miss firing it from the arrival callback `0x61b460`, so the feed holds a fresh roll's event until the template answers, with two releases that are ours: a negative answer (a frame that never opens cannot even be passed on) and a 2 s deadline paid out of the roll's minute; `arg2` stays the wire's countdown, as `0x61b430` pushes it (2010) - the FPS journal ships to players: it had registered inside the dev-only `DevToolsPlugin` and been armed by an environment variable, so nothing we shipped could have written a row on the one GPU-bound frame in the corpus, a Steam Deck's at 94 % busy; `/console fpsJournal 1` — a CVar of our own, persisted like every CVar — opens `benilla-config/Diagnostics/fps-journal.csv` and appends one row a second, `0` closes it mid-run, and `WOW_FPS_JOURNAL=<path>` stays as the harness lever; eight GPU columns appended, `gpu_ms` then `gpu_opaque, gpu_static, gpu_transp, gpu_glow, gpu_post, gpu_ui, gpu_other`, read off bevy's `RenderDiagnosticsPlugin`, which times passes where the device offers `TIMESTAMP_QUERY_INSIDE_PASSES` (Vulkan and DX12) and leaves the cells empty on an Apple GPU, empty being the honest value; `static_gx`, the four `ffx_glow_*` passes and `ui_gamma_decode` open diagnostic spans so a city's own draw is named in the split; a fresh file opens with the adapter, backend, driver and `gpu_spans yes|no` line; and a probe's `/console` line, which skips the stock `ChatEdit_ParseText` and had landed in a parser arm that knew only `reloadUI`, now forwards to `ConsoleExec` and writes a CVar the way the typed line does (2008) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

//! The render-world half of the B1 retained pass (see `mod.rs`; decision 1429): extraction of
|
|
//! the published cell set, per-cell GPU assembly (texture-array classes + the item→layer
|
|
//! table), the pipeline family, and the draw node between the main opaque and transparent
|
|
//! passes.
|
|
//!
|
|
//! Assembly happens where each fact lives: the MAIN world bakes geometry (it owns the
|
|
//! submeshes) but cannot know texture dims/format (BLP images are `RENDER_WORLD`-only), so
|
|
//! classing into `texture_2d_array`s happens HERE, once each member's `GpuImage` is resident.
|
|
//! A cell whose textures aren't all loaded yet simply isn't drawn that frame (the entity path
|
|
//! streams batches in piecewise; cell-granular appearance is the same arrival class, mostly
|
|
//! under the load cover).
|
|
//!
|
|
//! **The arrays are ONE SHARED POOL, not per-cell (B3, decision 1432)** — `pool.rs` owns the
|
|
//! design note (the two driver taxes 1431's `sample` caught, and how dedup + drain-once +
|
|
//! sibling growth remove them structurally). Here, a re-bake costs a record table and a few
|
|
//! bind groups, never a texture.
