AgentTranscriptMaterializer

object AgentTranscriptMaterializer

Turns every agent transcript under dev_docs/agents/transcripts/ into a loadable Field document — a <out>/<name>/metadata.edn scene an editor/welcome can open, run and edit. This is how the transcript corpus becomes both the docs gallery workspace and the welcome "starting points": one source of truth (the yaml), documents derived at build time.

BoxCodeCompileGuard.kt

src/jvmMain/kotlin/afield/examples/BoxCodeCompileGuard.kt — read the source

BoxCodeCompileGuard

object BoxCodeCompileGuard

The landing guard that box code still compiles: each named transcript goes down the path DemoTranscriptExecSmokeTest classifies it for. COMPILE_ONLY transcripts (the ones that would open a window) build their graph and compile with evaluation skipped; EXECUTE transcripts are headless-safe and run, because a later box may need what an earlier one defines when evaluated; KOTLINJS transcripts compile through the Kotlin/JS path.

ClothSimulationExample.kt

src/jvmMain/kotlin/afield/examples/ClothSimulationExample.kt — read the source

ClothSimulationExample

object ClothSimulationExample

Demo of Cloth — the reusable grid-cloth builder over SimdVerlet's 4-slot distance constraints. All of the physics lives in Cloth now; what is left here is the part that is genuinely example-shaped: standing up a simulation, wrapping the frame loop so the grabbed particle gets a red crosshair, and the process-level "most recent simulation" handle that lets an interactive box call grabNearest without holding one.

Declaration	Summary
class InteractiveClothSimulation internal constructor(val cloth: Cloth, val frames: Sequence<List<FLine>>)	Interactive cloth simulation handle with externally callable grab controls.

DocumentToTranscript.kt

src/jvmMain/kotlin/afield/examples/DocumentToTranscript.kt — read the source

DocumentToTranscript

object DocumentToTranscript

Writes an OperationTranscript yaml from a saved Field document — the reverse of AgentTranscriptMaterializer. It is how a document built by hand, or a nightly demo under dev_docs/agents/demos/, becomes a transcript in dev_docs/agents/transcripts/ without anyone retyping its boxes: the document is what the boxes currently contain, so the transcript is generated from it, never paraphrased.

Declaration	Summary
class Result(val yaml: String, val boxes: Int, val omitted: List<String>, val notCarried: List<String>)	What one conversion produced. omitted are things the transcript leaves out on purpose and says so in its header; notCarried are values this writer cannot spell, which the round trip treats as failures.
fun main(args: Array<String>)
fun convert(document: File, name: String = document.name): Result	Load document in a fresh session and write its transcript.
fun roundTrip(document: File): List<String>	Convert document, rebuild the transcript's graph through the real apply path, and list every difference between the rebuilt boxes and the loaded ones. Empty means the transcript is the document.

The Kotlin→JS half of dev_docs/REMOTEJS_BOX_PARITY.md: a // {{ remoteAR }} box compiles against display, slider, checkbox and setTimeout (bound to the head's field.js globals), and an exception thrown inside the Kotlin stdlib maps, through the module's source map, to the editor line of the box's own code rather than to the generated JavaScript line (an inline stdlib function marks the line that called the user function it was expanded into).

Validates the expanded RemoteAR surface (math types + vec/clearAll + the dynamic-with-typed- completion stage) by compiling a sample that exercises it against the GENERATED compiler declarations — the real check that the binding model emits valid external Kotlin/JS for every new name and that they type-check together. Also asserts the dynamic (compiler) vs Stage (completion) split so stage.foo = x stays permissive while stage.add| gets completion.

Validates the Tone.js computer-music head profile (// {{ tone }}) by compiling a sample that exercises a broad slice of the surface against the GENERATED compiler external declarations — the real proof the ToneKotlinJs binding emits valid Kotlin/JS for every bound name and that they type-check together. Also asserts the marker routes to the tone profile and the parity/dynamic split invariants (afield.graphics.KotlinJsBinding) hold for the Tone surface.

KotlinToJsSpikeTest

object KotlinToJsSpikeTest

Proves the Kotlin->JS RemoteJS seam end to end, in-process from a Field JVM: 1. A self-contained Kotlin snippet that uses operator fun plus (the thing ASTA exists to fake in raw JS) compiles to a single plain-module JS string via KotlinToJsCompiler. 2. A deliberately broken snippet surfaces a structured compile diagnostic (line + message), i.e. errors are catchable at the Kotlin source before the browser ever runs anything. 3. If node is on PATH, the produced JS is actually executed and its output verified — proving the module is directly eval-able (which is what the head's global.eval(code) needs).

RectslBoxToolsSmokeTest

object RectslBoxToolsSmokeTest

Step-2 slice for box-authored AI tools: the RectSL studio tool set + the image-return and box-state-escape primitives. Drives the REAL box path — a box whose code declares a ki-var and calls registerRectslStudioTools() (unqualified, via the intro import) — then asserts, without a live model and without requiring a GPU: - rectsl.check compiles good source and reports diagnostics for bad source; - a {{ … }} escape compiled against the box's engine reads the box's live ki-var (the "escapes reference box state" requirement) — prewarmed off the runloop, then invoked; - the image-return primitive marshals correctly (base64 kept out of the JSON output); - rectsl.run fails gracefully (a structured tool error) when no renderer is in context — the GPU happy-path reuses the gallery-proven RectSLRenderRunner and runs in a live document.

OpenDlssNrLiveEditSmoke

object OpenDlssNrLiveEditSmoke

Live edits that used to need a box rerun. OpenDlssNrStudy.reload with a new varying between the stages rebuilds the source and the next frames draw with it; with the native library present, a pass added to a Fabricate post stack leaves that stack when it closes.

FnRewriteKotlinLiveBoxProbe.kt

src/jvmMain/kotlin/afield/examples/functions/FnRewriteKotlinLiveBoxProbe.kt — read the source

FnRewriteKotlinLiveBoxProbe

object FnRewriteKotlinLiveBoxProbe

Runs one rewriteKotlin spec inside a live box, headlessly, in seconds.

Declaration	Summary
fun verifiedNegativeCache()	Called only after the live compiler rejection, repair and invalidation assertions pass.
fun tick()	Called by the box body, once per entry.
fun main(args: Array<String>)
fun run(mode: String)	The two modes share this whole harness, and the only difference between them is which box's engine the @{...} snippet is compiled in. Mode is a parameter and not an environment variable because run_field_tests.py drives the entrypoint through a Field server it starts itself, so the caller's environment never reaches this JVM.

StackSLStudyGpuSmoke

object StackSLStudyGpuSmoke

Proof that a StackSL study's GPU frames are the program's frames: the same programs rendered by afield.lang.stacksl.study.StackSLGpuRasterizer on a live renderer and by the CPU reference. Exact arithmetic, smooth-transcendental tiers, and the 2D fBm palette have hard bounds; the 4D fbm4 hash comparison remains diagnostic because tiny differences in its warped coordinates can cross hash lattice boundaries. uv saturate must be bit-identical, which catches a flipped image.

const val LLM_ONLY_CALLS	Model calls the llm-only arm stops at: what frequent averaged per run at 1,200 renders.
fun heldOut(name: String, dim: Int): StackSLTarget?	Targets nothing was tuned on. The watchmaker's prompt was revised while looking at runs on the five built-in targets, so a result on those alone could be a prompt fitted to them; these were written afterwards and never looked at before the run that measured them.

fun curves(dirs: List<File>, out: File, side: Int = 128)	Resemblance over time, for a plot: every saved run in dirs (s<seed>-<target>-<arm>.json), every new best program it found, with the renders it took, that program's layout agreement at side px and its skill under the trial's one referee (LPIPS at 32 px over the whole picture, the same for every stage and arm), as CSV rows arm,target,seed,generation,renders,layout,skill,origin.

WfcGallery

object WfcGallery

Renders — and verifies — the figures behind [public/docs/wfc_examples.md].

Declaration	Summary
const val DEEP	Terrain IDs, in the order that makes them a chain: each may only touch its neighbours.
const val SHALLOW
const val SAND
const val GRASS
const val FOREST
const val TERRAIN_COUNT
val TERRAIN_COLORS	ARGB, opaque. Chosen so the five bands are unambiguous at one pixel per cell.
val TERRAIN_NAMES
fun terrainMap(w: Int, h: Int): IntArray	A quantised smooth elevation field: three overlapping bumps sliced into five bands.
fun terrainTile(terrain: Int, tileSide: Int): IntArray	One 8x8 tile per terrain: a flat base plus a fixed dither.
fun terrainPixelImg(w: Int, h: Int): Img	The terrain map at one pixel per cell — the source the overlapping model reads.
fun terrainTiledImg(w: Int, h: Int, tileSide: Int = 8): Img	The terrain map with each cell drawn as an 8x8 textured tile — the simple-tiled source.
val SKY
val SOIL
val STEM
val BLOSSOM
const val FLOWERS_SOIL_TOP	Row at which soil starts in flowersSource; everything above it is sky, stem or blossom.
fun flowersSource(w: Int = 26, h: Int = 18): IntArray	The overlapping model's source: sky over soil, with a few flowers rooted in the soil.
fun flowersImg(w: Int = 26, h: Int = 18): Img	flowersSource as an Img.
val CIRCUIT_SOCKETS	Socket per edge, in WFC_NORTH, WFC_EAST, WFC_SOUTH, WFC_WEST order; 1 = a trace leaves here.
val CIRCUIT_NAMES
fun circuitRules(): WfcRules	Rules from edge sockets: b may sit east of a exactly when a's east socket matches b's west socket. This is the original "simple tiled model", stated directly instead of inferred.
fun circuitTile(tile: Int, side: Int = 11): IntArray	11x11 tile art for the circuit set: a centre pad plus a trace out to each live socket.
fun circuitTileSet(side: Int = 11): PngTileSet	A PngTileSet assembled from hand-drawn art rather than sliced from a source image.
fun checkOutputSatisfiesRules(label: String, rules: WfcRules, grid: IntArray, w: Int, h: Int)	The invariant that matters: every adjacent pair in grid must be allowed by rules.
fun checkNotDegenerate(label: String, grid: IntArray, tileCount: Int, minDistinct: Int, maxShare: Double)	Guards the two failure modes that still look like a picture: one tile everywhere, or noise.
fun checkSymmetric(label: String, rules: WfcRules)	Adjacency must be a symmetric relation or the solver cannot enforce it. See WfcRules.findAsymmetry.
fun checkOutputUsesObservedPairsOnly(label: String, rules: WfcRules, grid: IntArray, w: Int, h: Int, maxInvented: Int = 0)	The stronger form of checkOutputSatisfiesRules: every adjacent pair must be a pair the sample actually contained, not merely one the widened table permits.
fun terrainPairs(terrain: IntArray, w: Int, h: Int): Set<Pair<Int, Int>>	The unordered set of terrain pairs that touch (east or south) in a terrain grid.
fun checkStructureReused(label: String, source: IntArray, sw: Int, sh: Int, output: IntArray, ow: Int, oh: Int)	The human-legible form of "it reused the source's structure": the output may only contain terrain edges the source contained.
fun coherence(grid: IntArray, w: Int, h: Int): Double	Fraction of 4-adjacent cell pairs that hold the same value — "how blobby is this".
fun floatingBlossoms(pixels: IntArray, w: Int, h: Int): Int	Which output pixels are blossoms whose pixel directly below is not a stem.
fun meanBranching(rules: WfcRules): Double	Mean number of tiles allowed per (direction, tile) — the model's branching factor.
val STRIPE_COLORS
fun diagonalStripeSource(w: Int, h: Int): IntArray	Diagonal stripes two cells wide — a source built so the neighborhood choice provably matters.
fun diagonalStripeImg(w: Int, h: Int, tileSide: Int = 8): Img	diagonalStripeSource drawn as flat 8x8 tiles.
fun antiDiagonalBreaks(grid: IntArray, w: Int, h: Int): Int	How many cells break "the anti-diagonal neighbour has the same tile" — 0 means clean stripes.
fun quantisedField(w: Int, h: Int, levels: Int): FloatArray	Quantised smooth field, the source both float paths learn from.
fun roughness(values: FloatArray, w: Int, h: Int): Pair<Double, Double>	Mean absolute difference between horizontally / vertically adjacent values.
