The built in video capture removed: key 8, debugVideoCaptureStart, Stop and IsActive, debugRenderPost, the loop's render after every update while capturing; the FAQ shows recording frame by frame at an exact 60 fps with setEngineManualStep and engineStep, the snippet run in headless Chrome first

Bench: PixiJS and Phaser pinned to 8.22.0 and 3.90.0 with sha384 integrity, as three.js and CodeMirror already were, so a CDN change can not run new code on the site or shift the numbers

Medals unlocked before the first medalsInit are kept and saved by it (a later medalsInit with another save name starts from its own), the debug assert on an early unlock gone; Node 22.12 or later for the package's build and tests, as CI runs

Open lows, the rest: drawTextureWrapped keeps its tinted bake per image (bakeTintedImage into a context of its own) and honors TextureInfo.pixelated; the 2D editor's Save sets the baseline outside the write's catch, retires code made layers' records once gone, and judges a point or rectangle by its top in a shrink; docs for align2D, prefab export, timeScale, the engineStep example, Box2D's unused EngineObject fields and restart determinism

Open lows, plugins: a tween that throws stops no others (its step in tweenStep, the first error rethrown after the walk); parseGLTF takes typed arrays and Node Buffers; glTF accessors off alignment and sparse ones past their buffer named; getRotation from atan2 of the pitch's sine and cosine; getNearestClearNode walks the ring only, in the same order; ParticleEmitter3D's particleCall and particleCollide private; parseAtlas's return typed

Open lows, core: a release and press in one frame keep both, a non-repeat keydown of a held key is not a press; fullscreen's promise caught; Canvas2D honors TextureInfo.pixelated; tile layer shadows from solid cells only; the main canvas's alpha, filter and shadow reset each frame; mainCanvasSize set in place; NaN colors black in release; glDeleteTexture does its own cleanup

2D object collision through a grid once there are 64 solids or more (engineCollideGridMin): a mover gets the solids near it in list order, found again when a push moves it; the grid follows each solid after its physics and the other object after a collision callback; every contact resolves exactly as checking every pair, tests run scenes both ways and compare every value, callbacks that throw the other far away or destroy it included; 2000 movers about 1.3 s to 12 ms a frame in the vm

Examples: the raycaster walks on a phone; raycasting, hill glide, vibrate, nine slice, animation and parallax size from the view; the shorts that need tile padding set it themselves; the module and TypeScript examples match the starter again; htmlMenu finds its elements by id; four 3D shorts share one mesh; the 3D puzzle shows SOLVED once the last block lands; fillStyle written one way

JSDoc polish: first description lines without a closing period where the description ends there or a list follows, the Box2D joint getters and setters and Box2dObject's debug draw say what their values do, and the engine's own fields that reached the d.ts as any typed (render3D.uniforms, VoxelMap.chunksChanged and tiles, GLTFModel.nodeTree, Prefab3D.parts and partObjects, the Newgrounds lists)

Shader code after the engine's main in the 2D Shader, the 3D Shader and the post process, mainImage declared ahead, so a define in a game's code can not rewrite the engine's names (smoke checks with a define of d in 2D and C in 3D, which drew black before); the 3D discard moved to the end of main, after the normal map's derivatives and the emissive sample
