Prompt for this run

Build an interactive 3D 3 by 3 Rubik's Cube using the provided Three.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `three.min.js` (global `THREE`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Start solved, with six distinct face colors and visible cubie boundaries. Preserve cubie and sticker state through moves; recoloring a static cube is not sufficient. - Provide visible buttons for U, D, L, R, F, B quarter turns and their inverses. Animate each move and queue or disable further moves until it completes so state is not corrupted. - Dragging the background orbits the camera without turning a face. Keep the cube fully visible initially and support bounded wheel zoom. - Provide Scramble, applying a sequence of legal turns, and Reset to restore the solved cube and initial camera. - Only core global THREE is provided; implement camera controls without importing unavailable addons. A solver is not required. Verify: Turn one face and apply its inverse, checking that the visible stickers return to their starting arrangement. Orbit the camera to inspect the cube from another angle, then use Reset and check the solved appearance and initial framing.

Let me build a Rubik's cube in one index.html. Key design:

- 27 cubies (or 26 visible), each a THREE.Mesh with rounded-ish box + sticker planes per face. Simpler: each cubie is a BoxGeometry with black material, plus sticker planes on outer faces.
- Move logic: pick cubies in a layer by position, rotate group around axis by 90°, animate with quaternion, then snap positions.
- Approach: use a pivot Object3D, attach layer cubies to pivot, animate pivot rotation, on complete detach and round positions/quaternions.
- Buttons U D L R F B and primes.
- Orbit controls: custom pointer drag to rotate camera around target with spherical coords; wheel zoom clamped.
- Scramble: queue of random moves, animate sequentially. Reset: rebuild cubies and camera.
- Disable buttons while animating (or queue). I'll disable during animation.

Implementation details:

Cube coordinates: positions at x,y,z ∈ {-1,0,1} (spacing 1.05 maybe). Keep logical coords integer for rounding.

Cubie mesh: BoxGeometry(0.98) with MeshLambertMaterial black-ish for body, plus sticker meshes PlaneGeometry(0.82) offset 0.495 in face direction, colors per face: U white (+y), D yellow (-y), R red (+x), L orange (-x), F green (+z), B blue (-z). Stickers only on outward faces (where coord = ±1 along that axis).

Rotation: for move U: layer cubies with y≈1, rotate about axis (0,1,0) by -90°? Standard: U turns top clockwise viewed from above → rotation about +y by -π/2 (clockwise from outside means negative angle around axis pointing out). Let's define: each face turn is 90° clockwise when viewed from outside the face. For face with outward normal n, clockwise viewed along -n... Let me just define angle = -π/2 about the face normal axis for a clockwise turn. E.g., R: axis +x, rotate by -π/2 about +x gives clockwise viewed from +x. Yes: rotation about axis a by angle θ; viewed from +a looking toward origin (i.e., looking along -a), positive θ (right-hand rule) appears counterclockwise. So clockwise = -π/2.

Move table:
U: axis (0,1,0), layer y=1, angle -π/2 (for U), +π/2 for U'.
D: axis (0,-1,0), layer y=-1, angle -π/2 about -y → clockwise viewed from below. In world terms that's +π/2 about y. Just compute using axis = normal, angle = -π/2 for prime-less.
L: axis (-1,0,0), layer x=-1.
R: axis (1,0,0), layer x=1.
F: axis (0,0,1), layer z=1.
B: axis (0,0,-1), layer z=-1.

Animation: create pivot Object3D at origin, for each cubie in layer: pivot.attach(cubie) (THREE r Attach preserves world transform; use Object3D.attach available in global THREE). Animate pivot.rotation on axis from 0 to angle with easing over ~250ms. On finish: pivot.updateMatrixWorld; for each cubie: scene.attach(cubie) (or cubeGroup.attach), then round cubie.position components to nearest of {-1,0,1}*spacing and snap quaternion: round rotation matrix elements to nearest integer (since axis-aligned after 90°). Simplest: snap quaternion by converting to matrix, rounding elements.

Spacing: 1.0 with cubie size 0.96, gap shows black background? Better spacing 1.0, size 0.95, stickers 0.85 at 0.478 offset... use size 0.94, sticker plane offset halfSize+0.001.

Actually to have "visible cubie boundaries", black body with slight gaps works.

Camera: PerspectiveCamera at spherical (r=8ish, theta, phi) target origin. Custom orbit: mousedown on canvas (not on cube? dragging background orbits — dragging anywhere should orbit; but requirement says dragging background orbits without turning a face. We don't implement face-drag turning at all, so dragging anywhere orbits. That's fine and simpler; dragging cube also orbits, which doesn't turn faces — acceptable since no face-drag needed).

Zoom: wheel changes radius clamped [5, 14].

Buttons UI: grid of buttons: U U' D D' L L' R R' F F' B B', Scramble, Reset. Disable while busy.

Scramble: 20 random moves (avoid same face consecutive inverse? just random, allow). Queue moves, run sequentially. Buttons disabled during scramble too; I'll implement a queue that processes moves one at a time; buttons push to queue? Requirement: "queue or disable further moves until it completes". I'll disable buttons (busy flag) — simpler and safe. Actually queue is nicer for UX but disabling is explicitly allowed.

Reset: rebuild all cubies (dispose old), reset camera spherical to initial.

Rounding quaternion: after detaching, cubie.quaternion from pivot rotation should be exact-ish; snap: take matrix, round elements. Implement snapQuaternion: m = new Matrix4().makeRotationFromQuaternion(q); round each of 9 elements; then setFromRotationMatrix.

Rounding position: round to nearest spacing multiple: p = Math.round(pos/spacing)*spacing. With spacing 1.0 and logical coords -1,0,1.

Let me write code.

Structure:

```js
const COLORS = {U:0xffffff, D:0xffd500, R:0xc41e3a, L:0xff5800, F:0x009e60, B:0x0051ba};
const STICKER_DEFS = [
 {name:'R', axis:new THREE.Vector3(1,0,0)}, ...
];
```

Build cubie: for x,y,z in -1..1: group; body Mesh(BoxGeometry(0.94), bodyMat). For each sticker def, if coord along axis equals sign: plane rotated to face direction, position at axis*(0.47+0.002), color. Plane default faces +z; orient: for +x: rotateY(π/2); -x: rotateY(-π/2); +y: rotateX(-π/2); -y: rotateX(π/2); +z: none; -z: rotateY(π).

Cubie logical position stored in cubie.position (units = spacing 1.0... but visually size 0.94 with spacing 1.0 gap 0.06 fine). Add slight bevel look? Keep simple.

Scene: background gradient-ish (just color), lights: ambient + directional.

Rotation animation with requestAnimationFrame using clock.

Also allow keyboard? Not required.

Edge: pivot.attach requires objects added to scene graph; attach exists in THREE global (r1xx). Check three.min.js version — likely r128+ where Object3D.attach exists (added r109). Fine.

Write the file.

Buttons: label U, U′ etc. Use "U'" maybe. I'll use U′.

Move function:

```js
function makeMove(face, prime){ ... returns duration }
```

Queue: array of {face, prime}. processQueue: if busy return; if queue empty, enable buttons; else start anim.

Busy flag disables buttons (CSS class). Scramble pushes 20 moves, processes.

Snap after each move. Also after attach back, set position from logical rounding and snap rotation.

Let me also track logical coords? Positions rounded suffice.

Reset: remove cubies from scene, dispose geometries/materials (or reuse), rebuild. Simpler: store initial transforms? After moves, cubie transforms changed; rebuild fresh is clean. Rebuild function buildCube().

Initial camera: position spherical radius 9, theta ~ -35°... define via position (4.5, 4.5, 6)? Use spherical: phi (polar) 60°, theta 45°. I'll store initSpherical and reset.

Orbit: track spherical {radius, phi, theta}; drag: theta -= dx*0.005; phi clamp [0.15, π-0.15]. Update camera each frame or on event. Update camera.position from spherical around target (0,0,0); camera.lookAt(0,0,0).

Double-click? no.

Wheel: radius clamp [5,15], passive:false preventDefault.

Buttons disabled via busy: set button.disabled = true for move/scramble buttons; Reset always allowed? Reset during animation could conflict with the running pivot attach. Simplest: disable Reset during animation too, or cancel: on reset, finish current move instantly? I'll just disable all buttons while busy; keep it simple and safe. But allow reset anytime would be nice — skip; disable during animation.

Console check with browser tool.

Write index.html now.

Sticker geometry shared: one PlaneGeometry(0.86,0.86). Body geometry shared. Materials: body shared; sticker materials per color shared (6). Since we never recolor stickers (we physically move meshes), sharing is fine.

Highlight? no.

CSS: dark background, centered canvas, button panel bottom. Panel with grid.

Let me write.

Animation details: duration 260ms; ease inOut: t<0.5? use smoothstep t*t*(3-2t).

Scramble moves: random face from URFDLB, prime random, avoid immediate same face as previous.

Code:

```js
let busy=false, queue=[];
function enqueue(face, prime){ queue.push([face,prime]); processQueue(); }
function processQueue(){
  if(busy) return;
  const next = queue.shift();
  if(!next){ setButtonsEnabled(true); return; }
  setButtonsEnabled(false);
  busy=true;
  startMove(next[0], next[1], ()=>{
    busy=false;
    processQueue();
  });
}
```

setButtonsEnabled toggles .disabled on all buttons with data-move plus scramble button. Reset maybe always enabled if not busy.

startMove(face, prime, done):
- def = FACES[face]; axis normal vector; layer = cubies.filter(c => Math.round(c.position[comp]) === sign) where comp = 'x'|'y'|'z' based on axis.
- pivot = new Object3D; scene.add(pivot);
- layer.forEach(c=>pivot.attach(c));
- target angle = prime? +π/2 : -π/2 about axis... wait define: clockwise quarter turn viewed from outside = rotation by -π/2 about outward normal. So base angle for the move (non-prime) = -π/2; prime = +π/2. Animate pivot rotation: pivot.quaternion set from axis-angle each frame with current eased angle.
- On finish: pivot.updateMatrixWorld(true); layer.forEach(c=>{ scene.attach(c); snap(c); }); scene.remove(pivot); done().

scene.attach(c) — cubies are children of scene directly. But I want cube group? Not needed; add to scene. Fine.

snap(c): position components round to integer (spacing 1). quaternion snap via matrix rounding.

Note pivot.attach with world transforms: cubie world matrices—scene has no transform, fine.

Frame loop: renderer.render always (simple rAF loop), plus animation progress handled in loop.

Handle canvas sizing on resize.

Write file, then run browser checks: click R button, screenshot, click R′, screenshot compare; drag orbit; reset.

For drag simulation: browser tool drag from (600,400) to (700,380).

Let me write the code.

Also add slight bevel: use two materials? skip.

Buttons HTML:

```html
<div id="panel">
 <button data-face="U" data-prime="0">U</button>
 ...
</div>
```

Generate via JS to keep HTML small? Buttons must be visible; JS-generated is fine but ensure they exist even if JS partially fails — fine, JS builds them.

Actually generate in JS loop over ['U','D','L','R','F','B'] adding two buttons each, plus Scramble and Reset buttons in HTML.

Write it.

The tool says "model does not support images" — I can't see screenshots. So I must verify via DOM inspection and console evaluation. The browser tool gives dom and console. I can use "inspect" to get DOM. But I can't see pixels. I can still verify behavior programmatically? The browser tool only does clicks/drags/keys. I can't evaluate JS directly... unless console logs. I could add temporary console.log diagnostics? Better: I can verify logic by reasoning plus clicking buttons and reading DOM (e.g., disabled states). But state correctness (stickers return to start) is visual.

Alternative: I can temporarily add a debug hook to index.html: a hidden function that serializes sticker state, exposed as window.__state, logging to console after moves. The console output is returned by the browser tool. That lets me verify: initial sticker arrangement hash, after R move, after R' returns to initial.

Let me add a small debug: compute a string of face colors reading each sticker's world position/orientation? Simpler: track sticker colors per face by cubie position. For each sticker mesh (I can tag them), determine which face it's on by its world direction: take sticker's world normal (cubie quaternion applied to local normal) and cubie position. Build map: for face U (+y), collect cubies with y=1, sorted by (x,z), the color of sticker whose world normal is +y.

I'll add a debug function that logs a 54-char string, called on move completion, guarded by window.DEBUG flag. Then click R via browser, wait, read console via next action, click R', read console.

But console output appears in subsequent browser action results. Let me add the debug code permanently (harmless, tiny) or temporarily. I'll add it permanently but only log when location hash '#debug'? Simpler: always update a window.__faceState and console.log only if window.__debug. Then I can't set window.__debug via browser tool (no eval). Hmm.

Option: log to console every move completion — one line each. That's fine, console just gets lines. Add function describeState() and call console.log('STATE:'+s) at end of startMove and after buildCube/reset. Then run browser: click R, then next browser action returns console including the log after R completes... but timing: the click action may return before animation finishes (280ms). The following action's console snapshot should include it.

Let me add debug code.

The screenshot isn't visible to me, so I'll add lightweight state logging to verify sticker state via the console:

Oops, I wrote broken code (that describeState is incomplete and wrong — child is in cubie space; also I left it unfinished). Let me rewrite it properly: for each sticker mesh, world normal = local normal transformed by cubie's world quaternion (cubie is direct child of scene, no rotation on scene). Sticker's local normal in cubie space: the sticker's own rotation applied to (0,0,1). Then cubie quaternion applied to that gives world normal. Sticker world position = cubie.position + rotated offset — but easier to use cubie.position for sorting and determine face by world normal.

Rewrite describeState:

```js
function describeState() {
  const localN = new THREE.Vector3(), worldN = new THREE.Vector3();
  const map = { U: [], D: [], R: [], L: [], F: [], B: [] };
  const nameForColor = {};
  for (const n in COLORS) nameForColor['#' + COLORS[n].toString(16)] = n;
  for (const c of cubies) {
    for (const child of c.children) {
      if (!(child instanceof THREE.Mesh) || child.material === bodyMat) continue;
      localN.set(0,0,1).applyEuler(child.rotation); // sticker rotation
      worldN.copy(localN).applyQuaternion(c.quaternion).round();
      let face = null;
      if (worldN.y === 1) face='U'; else if (worldN.y===-1) face='D';
      else if (worldN.x===1) face='R'; else if (worldN.x===-1) face='L';
      else if (worldN.z===1) face='F'; else if (worldN.z===-1) face='B';
      if (!face) continue;
      const col = child.material.color.getHexString();
      map[face].push({ k: sortKeyFor(face,c), col: nameForColor['#'+col] });
    }
  }
}
```

Material color getHexString returns hex; COLORS stored as numbers — nameForColor keyed by hex string. 

Sorting: for each face define sort key from cubie position:
U: rows from top(viewed from front... whatever): key = (-x*3 + (-z)?). Doesn't matter for equality check as long as consistent. I'll use generic: key = `${Math.round(c.position.x)},${Math.round(c.position.y)},${Math.round(c.position.z)}` per sticker but two stickers can't share same cubie+face so fine. Sort by key string. Consistent across states? Keys are position-based which change after moves... but that's actually what we want: the state string represents which color is at which position on each face — comparing initial vs after R,R' requires the same ordering scheme, which position-based sorting gives.

So:

map[face].push({key: `${x},${y},${z}`, col}) then sort by key, join.

state string: FACE_ORDER.map(f => f + map[f].map(s=>s.col).join('')).join('|')

Log after buildCube and after each completed move: console.log('CUBE_STATE ' + state).

Let me replace the broken block.

Initial state is solved (each face uniform). Now test R turn: click R button. Buttons: first 12 buttons in #rows: U, U′, D, D′, L, L′, R, R′, F, F′, B, B′ — R is index 6 (7th). Their coordinates: rows container near bottom center. Rather than guess coordinates, use inspect to find DOM positions? The browser click takes x,y. Buttons are ~44px wide, gap 6. Panel centered at 600. 12 buttons → width 12*44+11*6 = 594. So first button starts at 600-297=303. R is 7th: 303 + 6*50 = 603 + 22 = ~625. Height: panel bottom 14px, rows ~34px + utils 34 + padding. Click y ≈ 800 - 14 - 44(utils height+padding) - 8 - 17 ≈ 800-83 = 717? Let me compute: panel padding 10 top/bottom; inside: rows (34px tall), gap 8, utils (34). Total inner = 76 + gap 8 = ... rows 34, gap 8, utils 34 → 76; padding 20 → 96; bottom 14 → panel spans y from 800-14-96=690 to 786. Rows row center ≈ 690+10+17=717. R center x: 303 + 6*50 + 22 = 303+300+22 = 625.

Click R, then wait for animation; next action (screenshot or another click) will show console. There may be a delay issue: clicking R, then immediately clicking R′ would be blocked because buttons disabled until animation done. The second click might happen while disabled — that actually tests the disable behavior. Then a later click after completion. But clicks are sequential actions; each action presumably takes some time. Let's click R, then click R′ (should be ignored if still animating, which tests the lock; but if the tool waits enough between actions, animation completes and R′ works). Then reload-ish check state.

Alternatively click R, inspect (returns console), click R′, inspect. Let's do that.

Solved state confirmed. Now click R (7th button, x≈625, y≈717):

No "R done" logged — so either the click missed the button or the click was on a different button. DOM text shows buttons but no disabled info. Let me check exact button coordinates via inspect — the inspect only returns text. Hmm.

Maybe the click hit the button but busy check: click handler calls enqueue; busy false; queue push; processQueue; busy=true; setButtonsEnabled(false); startMove. That should log after 280ms. Two actions passed (each presumably seconds apart), still no log. So click likely missed. Maybe y coordinate wrong or panel layout different (12 buttons may wrap into two rows? max-width 560px < 594 needed → wraps!). #rows max-width 560, buttons row wraps: first row 11 buttons (11*44+10*6=544 ≤560), second row 1 button? 12 buttons need 594 > 560, so 11 fit on first row, B′ wraps to second row. That changes positions: rows height 34+6+34=74. Panel taller. R (7th) center: x = 303+6*50+22=625, y = 800-14-2*10-34-6-34-8... let me recompute panel: inner height = rows(74) + gap 8 + utils(34) = 116, padding 20 → 136, bottom 14 → panel top = 800-150=650. Rows first line center = 650+10+17=677. So R at (625, 677). My earlier click at 717 was in the gap/utils region... 717 would be second row area maybe (690..724 = second row of buttons) — at x 625 there's nothing on second row (only B′ on far left). So click missed.

Let me get precise geometry via inspect of DOM — tool only gives text. I'll just click at (625, 677) for R.

The #rows container likely wraps (max-width 560px), shifting button positions. Let me click at the corrected coordinates:

Still no R done log. Maybe clicks aren't hitting at all, or my geometry estimate is off. Let me widen #rows max-width to avoid wrapping (set to 640px) so layout is deterministic, and also remove the debug logging timing guess by checking again. Also maybe the click coordinates map differently (device pixel ratio? viewport 1200x800). Let me make layout single-row: change max-width to 700px. Then 12 buttons: 594 wide, starts at 600-297=303, y: rows height 34, panel inner 34+8+34=76, padding 20 → 96, bottom 14 → top 690, row center 690+10+17=717.

But before, click at (625,717) failed even though that matches the non-wrapped math... unless it wrapped. Ugh. Let me just verify with a bigger target: temporarily? No — better approach: attach click handlers via event delegation? The handlers exist. The issue is purely geometry.

Alternative: use keyboard? Not implemented. I could add keyboard shortcuts (nice feature anyway) — then verify via key presses with browser key action. Let's add keydown: u/U' with shift? Use letters: u,d,l,r,f,b for moves, shift+letter for prime, s scramble. That gives reliable verification. Also fix wrap.

Actually, maybe the click did register but on a wrong button (e.g., panel padding?). If it registered on any button, some log would appear after 280ms. Two subsequent snapshots showed nothing, so likely no button was clicked... OR the pointerdown/pointerup dance: browser click dispatches mousedown/mouseup? My handlers use pointerdown/up for canvas only; buttons use 'click'. Should be fine.

Wait — could the click have hit the canvas and started a drag? y=717, panel is there. Hmm.

Let me widen rows and add keyboard support, then re-test.

No state log appeared, so the click likely missed. I'll make the layout single-row (deterministic coordinates) and add keyboard shortcuts as both a feature and a reliable way to trigger moves:

"R done" state: 
U face: UUUUUUUFFF — U face stickers: positions sorted by key x,y,z. U face has 9 stickers, positions y=1. After R turn, U face right column (x=1) should become F colors (the front-right column goes to up). U row: keys sorted lexicographically: (-1,1,-1),(-1,1,0),(-1,1,1),(0,...),(1,1,-1),(1,1,0),(1,1,1) → string "UUU UUU FFF" — last three = x=1 column = F. Correct for R turn (front goes up on right side). D face: DDDDDDDBBB — last three (x=1,y=-1) = B? After R, bottom-right column goes to back... Actually R clockwise: U→B? No: R turn moves F→U→B→D→F. Front right column → up right column. Up right column → back. Back left... hmm wait: R clockwise viewed from +x: F→U, U→B, B→D, D→F. So D face x=1 column gets B colors ✓ (DDDDDDDBBB: last three = B ✓). F face: FFFFFFFDDD — z=1 face x=1 column = D ✓. B face: BBBBBBBUUU — hmm, B face keys sorted: (-1,y,-1),(-1,y,0),(-1,y,1),(0,y,-1)... x=-1 column first: B B B, then middle B B B, then x=1: U U U? Wait, U→B means up right column goes to back, but on the back face that's x=1 or x=-1? When up right column rotates to back, its x stays 1. So B face x=1 column should be U. Keys sorted ascending: x=-1 first (9 chars BBB), x=0 (BBB), x=1 (UUU) → "BBBBBBBUUU" ✓. All consistent. 

Now press R again with shift → R′.

R turn verified correct (F→U→B→D→F on the right layer). Now apply the inverse:

Problem! After R then R′, the state is NOT solved: "UUUUUUUDDD|DDDDDDDUUU|...|FFFFFFFBBB|BBBBBBBFFF". That means R′ moved things wrongly: U right column became D colors, etc. It looks like R′ rotated the layer the wrong direction relative to R... wait R′ should undo R exactly. R: U col gets F; R′ applied after should give back U. Instead U col got D — that's R² essentially? No wait: R gives U=F,D=B,F=D,B=U. Then another turn in the same direction would give U col = D. So R′ turned in the SAME direction as R! So prime flag isn't working, or shift+R produced 'r' key? key "R" with shift — e.key would be "R", shiftKey true → enqueue('R', true). Hmm, but result shows same direction.

Wait, actually let me recheck: R clockwise from +x: F→U? Let me re-derive. Rotation by -90° about +x. Right-hand rule about +x by angle -90°: a point at +z (front) moves to... rotation about x by angle θ: y' = y cosθ - z sinθ; z' = y sinθ + z cosθ. θ=-90: cos=0, sin=-1. Point (0,0,1): y' = -1*... y' = y*0 - z*(-1) = z = 1 → moves to +y (top). So F→U ✓. That's what R did (U col became F) ✓.

R′ = +90° about +x: (0,0,1): y' = -z*1 = -1 → F→D. U→F: point (0,1,0): z' = y*sin90 = 1 → U→F ✓. So after R,R′ state should be solved.

Observed after second move: U col = D, D col = U, F col = B, B col = F. That equals applying R twice (R: F→U→B→D; two R's: F→B, so U col = D ✓ matches R²). So the second key press did another R, not R′.

Why? Shift+R: e.key = "R", toUpperCase "R", e.shiftKey should be true. Unless the browser tool's key action doesn't set shiftKey (sends 'R' char without shift modifier). Then enqueue('R', false) → another R. That's a harness limitation, not app bug necessarily.

Alternatively test prime via clicking the R′ button. But earlier clicks failed to hit buttons... Now layout is single-row. Panel: rows one line (34px). Panel top = 800 - 14 - (10+34+8+34+10) = 800-110=690. Row center = 690+10+17 = 717. Buttons start x = 600 - (594/2) = 303. R′ is 8th: 303 + 7*50 + 22 = 675. So click (675, 717).

But earlier click at (625,717) (which was R position then, wrapped layout) didn't work. With the new unwrapped layout, (625,717) should be R. Earlier failure could've been due to wrap. Let me first verify a click works: click R button at (625,717), inspect. If log appears, clicking works now. Then click R′ (675,717).

Actually to save steps: current state is R² (still not solved). Plan: click R′ twice? Let me first test click R at (625,717): if works, state becomes R³ (equivalent to R′). Then click R′ button to get back to solved? R³ then R′ → R² not solved. Hmm.

Better: click R′ (675,717) now: if clicks work and prime works, state R²·R′ = R → U col = F. Then click R′ again → solved. Both clicks test button geometry and prime logic. If first R′ click turns same direction (R³), then prime is broken in click path? Buttons pass prime explicitly (prime=true), so direction should be +90. Let's go.

State after the second move shows R ran again rather than R′ — likely the harness's Shift key wasn't applied. Let me test the R′ button directly (8th button, x≈675, y≈717):

Still no new log — the click at (675,717) also missed. So clicks at button area aren't registering at all. Maybe the button coordinates are different than I compute. Possibly the viewport is 1200x800 but devicePixelRatio scaling? Or maybe panel is wider/narrower. Let me check the actual geometry by adding a temporary visual indicator... Or use the browser tool's click with inspect of element positions — not available.

Alternative approach: make buttons bigger and verify geometry differently. Or simpler: test inverse logic via keyboard by checking whether shiftKey works — instead of relying on shift, I could map keys: hold shift unclear. Alternative keyboard scheme: lowercase = clockwise, uppercase via 'r' twice? Hmm.

Better: change keyboard handler so shift isn't needed: use e.code? Same issue.

Alternative: verify prime by queueing from code? No eval available.

Let me debug why clicks miss. Maybe the browser tool click coordinates are relative to a different origin (e.g., the tool clicks at page coordinates but the iframe content is scaled?). Title DOM text appears. Perhaps the click works but at those coords there is the canvas and my canvas pointerdown handler... clicking canvas wouldn't log.

Maybe the panel isn't where I think. Font sizes/buttons min-width 44px, padding 10 → actual width maybe 44+20=64? No—min-width includes padding? box-sizing default content-box: min-width 44 applies to content; padding 10 left/right adds 20 → button ~64px wide. Then 12 buttons: 12*64+11*6 = 834 > 660 max-width → wraps again! Buttons min-width 44 with content 'U' → content width = max(44, text ~8px) = 44; total 64. So buttons are 64 wide. Row: 10 buttons = 10*64+9*6 = 694 > 660 → 9 per row? 9*64+8*6=624 ≤ 660 ✓. So rows wrap: 9 + 3. That explains misses!

Fix: set box-sizing: border-box on buttons and remove min-width weirdness. With border-box, width = max(min-width 44, content+padding) → 'U' content tiny so 44px. 12 buttons = 12*44+11*6 = 594 ≤ 660 single row ✓. Let me add `box-sizing: border-box;` to button CSS and also give buttons a fixed width 48? min-width 44 with border-box: content smaller than min-width so width = 44 ✓.

Also recompute after fix: buttons 44 wide. Row = 594, starts 303. R index 6 → x = 303+6*50+22 = 625; R′ index 7 → 675. y: single row: panel top = 800-14-(10+34+8+34+10) = 690, row center 717.

The buttons are wider than computed (default content-box sizing + padding), causing wrap. Fixing with border-box:

Still no move logged after clicking. Even after the inspect (later in time), no "R done". So clicks on buttons are NOT registering even with correct geometry... OR the click did register but a later inspect should show the log — nothing.

Hypothesis: the browser click tool dispatches a click at viewport coords, but maybe the panel is not at the bottom because... wait, maybe viewport is 1200x800 but rendering at different size? DOM text appears. Hmm, let me check whether click events reach the page at all: test clicking the canvas triggers... canvas pointerdown only sets dragging; no log. Add a global click logger? I can add a temporary console.log('CLICK', x, y, target) on document click. Then click somewhere and inspect the log to learn actual coordinates behavior.

Clicks still aren't registering. Let me add a temporary click logger to diagnose coordinates:

Let's click on the canvas area (not button) to see if any debug log appears — maybe only buttons generate one? Actually I added click listener to document, which should fire for any click. Test clicking the canvas at (600,400).

Click works and coordinates match (600,400 → canvas). So earlier button clicks at (626,717) and (675,717) reached the page but no click on BUTTON... The debug log would have shown "DBG click at 626 717 CANVAS" or BUTTON. We saw nothing at all — meaning click didn't dispatch at (626,717)? Odd. Maybe the panel isn't where I think. Let me click at (626,717) now and read the debug output.

The click at (626,717) hit the DIV (#rows), not a BUTTON. So buttons are NOT at that location. #rows spans that area but buttons are elsewhere — meaning the button row is positioned differently. Maybe the buttons wrap after all, or the panel is wider/taller. textContent shows "UU′DD′LL′RR′FF′BB′" all in the rows div.

Hypothesis: viewport width might be less than 1200? No, canvas click at 600,400 hit canvas regardless.

Wait — maybe the buttons don't render 46px wide because min-width with border-box... but also `min-width: 46px` with `padding: 0 10px` border-box → width 46 ✓. Unless the CSS I edited didn't apply because... let me measure by logging button positions via getBoundingClientRect on load. Add temp debug: after building buttons, log rects.

The click hit the DIV, not a BUTTON — buttons must be elsewhere. Let me log their actual rects:

Now I see button rects:
- Row 1: 317,659, 369,659, 421,659, 473,659, 525,659, 577,659 (6 buttons).
- Row 2: 629,659, 681,659, 733,659, 785,659 (4 buttons). Actually there are 6 per row, 12 total: row1 6, row2 6. R′ is 8th button, row2 index 1 after first row: row2 start 629, then 681 (R′). R is 7th button at 629. So R center x = 629+23=652. R′ center x = 681+23=704. y=659+17=676.

Thus clicks should be at (652,676) for R, (704,676) for R′. My earlier (626,717) clicked row 1 at x=317+50+23=390... wrong.

Let's click R at (652,676).

Now I know the actual button coordinates. R is the 7th button (center ≈652,676), R′ the 8th (≈704,676). Let's click correctly:

"R′ done" state returns to solved: UUUUUUUUUU|DDDDDDDDDD|RRRRRRRRRR|LLLLLLLLLL|FFFFFFFFFF|BBBBBBBBBB. Inverse turn returns cube to initial arrangement ✓.

Now test reset functionality: after an R turn, reset should restore solved and initial camera. Click Reset button: coordinates? Reset is in #utils panel; row1 (buttons) end at 837,659. Utils row: panel inner top=690 (since panel top 648, height 138 => bottom 786). Utils have Scramble and Reset button. They are min-width 110px, gap 10. Panel width 600; start x=300. Two buttons fit: Scramble at 300+10=310, width 110 → ends 420; Reset at 420+10=430 → ends 540. Centers: Scramble center ~365, Reset center ~485. y = 690+10+17=717.

Utils must be below: panel bottom 786, padding 10 → utils bottom ~776, height 34 → top 742, center ~759. Let me click Reset at (485,759).

Oops — clicked Scramble instead of Reset. That's fine actually: it tests Scramble! Let it run (22 moves, ~6.5s). Inspect after a few seconds to see queued moves executing sequentially. Then Reset test afterwards. Scramble center x ~365 though; I clicked 485 which hit Scramble? It says BUTTON Scramble — so Scramble is at 485?? Maybe utils buttons are centered differently: #utils has display:flex; gap:10px; not centered... it's inside panel with align-items:center? Panel has align-items:center, so #utils div is centered as a block: total width 110+10+110=230 → starts at 600-230/2=485... wait panel inner starts 310? Panel x=300,width 600, padding 14 left? padding: 10px 14px → left padding 14. Content width 600-28=572, centered #utils: starts at 300+14+(572-230)/2=300+14+171=485. So Scramble at 485..595, Reset at 605..715. Reset center ≈ 660.

Scramble now running. Wait then inspect.

That actually clicked Scramble — good, let's verify it animates through a sequence:

Scramble executed 22 moves sequentially, each with a distinct state, faces scrambled. Now test Reset: click at (660,759). Then check state solved + camera reset. Camera reset I can't verify visually, but code sets view to INITIAL_VIEW; I can verify by orbiting first then Reset, then... can't read camera. I could log camera position in reset. Let me add camera position logging to reset and orbit drag. Actually add logState('reset') and log camera pos after reset and after drags. Small additions:

- In reset(): after updateCamera(), console.log('CAM', camera.position...)
- After pointermove updates, too spammy; log once on pointerup with final camera pos.

Then: drag canvas (drag action), inspect log → camera changed; click Reset → camera back to initial (4.9..., etc.). Initial: radius 9.2, theta=π/5, phi=π/3: x=9.2*sin(60°)*sin(36°)=9.2*0.866*0.588=4.69; y=9.2*0.5=4.6; z=9.2*0.866*0.809=6.44.

Scramble ran 22 sequential moves correctly. Now let me add camera-state logging to verify orbit and Reset restore:

Only a click at (800,450) logged; no "CAM after orbit" log. The drag may have been executed as a quick click (down+up at target without intermediate pointermove), so camera moved little (no move events → no orbit change; endDrag logs only if dragging was true... dragging set true at pointerdown at start point (100,400)? But the click log says 800,450 — maybe drag dispatches pointerdown at (100,400), moves, pointerup at (800,450). Then endDrag should log. But no CAM log. Maybe the drag happened before my edit reload? No — I edited and the file was reloaded? I didn't reload after edit! The browser still runs old code without CAM logs. Need reload — but that resets state (currently scrambled). That's fine: after reload, do drag test, then Reset test.

Reload, then drag, inspect; then click Reset (660,759), inspect.

I need to reload for the new logging code, then re-test orbit + Reset:

Reset logged state solved and camera reset to (4.68 4.60 6.45) which matches expected initial view.

Now remove the debug logging (describing state, click logs, camera logs). Only required final cleanup: remove console.log statements that pollute output, but they don't affect functionality. However clean code recommended. Remove the debug lines: describeState, logState, click logger, and camera log in endDrag and reset. Also rect logging.

Remove:

- describeState function (inside the big comment I wrote), logState calls.
- document.addEventListener('click', ... DBG.
- requestAnimationFrame debug block for rects.
- console.log in endDrag.
- console.log in reset.

Remove also the `console.log('CAM reset'...` line.

After cleanup, final file is index.html.

Let me remove them.

Find lines:
describeState function: search for "function describeState". It's before "function logState". Actually I included both. Let's remove describeState function (start to end, leaving maybe function logState after it). Actually I also wrote logState function that calls describeState. I can just remove describeState and keep logState? No, logState calls describeState. I should just remove both describeState and logState, and remove logState calls.

Remove these lines (with some surrounding whitespace). But easier to write final version without debug. Since index.html is large (~450 lines), manually deleting all debug blocks may be error-prone. Instead I'll write a new clean version using file tools with all required features and remove debug. Let's produce final clean file.

Reset correctly restored the solved cube and initial camera view (CAM 4.68 4.60 6.45). Now let me clean up all debug logging to leave a production-ready index.html:

Now I'll write a clean version with all required features and debug statements removed. Remove:

- describeState and logState functions.
- logState calls (in buildCube, reset, startMove).
- Document click logger.
- requestAnimationFrame debug block.
- console.log in endDrag.
- console.log in reset for CAM.

Only keeping the core functionality: buildCube, move animation, buttons, keyboard shortcuts, orbit, zoom, scramble, reset, busy lock.

I'll rewrite the full file cleanly.

Now writing a final clean index.html without debug clutter:

→ write /tmp/job-PKAMkQ/index.html (11256 bytes)

Clean console — no errors from drag, R click, Reset click on the final build. All behaviors were verified earlier with the instrumented build (identical logic, only debug logs removed). The DOM shows the app running with no errors.

Summary of verification:
- Solved start state with 6 distinct colors and cubie boundaries: confirmed via state descriptor (uniform faces) and construction (0.94 cubies, 0.80 stickers, dark body).
- R then R′ via buttons: state string returned to solved — stickers preserved through animated moves (real geometry rotation + snap).
- Scramble: 22 sequential animated moves with correct state evolution and button disabling.
- Orbit drag: camera position changed (4.68,4.60,6.45 → 0.65,9.13,-0.89), no face turns.
- Reset: cube state solved again and camera back to initial (4.68,4.60,6.45).
- Zoom: bounded in code [5.5,16]; not directly exercised via tool (wheel event not simulated).
- Keyboard shortcuts implemented; shift+prime unverified via harness (shift modifier not delivered by tool), but prime verified via R′ button.

Unverified: visual rendering quality (screenshots not viewable), wheel zoom behavior, keyboard shortcuts in the final clean build (verified in instrumented build via key press for R).

The final clean build runs without console errors through a drag, an R button click, and a Reset click. All checks are complete. ## Summary **`index.html`** — a self-contained interactive 3D Rubik's Cube built on the local `three.min.js` (global `THREE`, no addons): - **Cube model**: 27 cubies (Groups), each a dark box with real sticker meshes on its outward faces (6 distinct colors). Moves physically rotate layer cubies around a pivot with `attach()`/`detach`, then snap position/rotation back to the exact grid — so cubie and sticker state is genuinely preserved through moves. - **Moves**: animated 90° turns (280 ms smoothstep ease) for U, D, L, R, F, B and their inverses via visible buttons; a busy lock disables all buttons during any animation, and moves run strictly sequentially (also keyboard shortcuts: letter = clockwise, Shift+letter = inverse, S = scramble). - **Camera**: custom orbit controls (pointer drag changes theta/phi, no face interaction), wheel zoom clamped to radius 5.5–16, initial framing at radius 9.2 that shows the whole cube. - **Scramble**: 22 random legal turns (no immediate repeats) animated one after another; **Reset** rebuilds the solved cube and restores the initial camera. **Verified with the instrumented build (state serialized from sticker world orientations, via console):** - Start state solved: every face uniform (`UUUUUUUUUU|DDDD...|...`). - Clicked **R**: right layer rotated correctly (F→U→B→D→F); clicked **R′**: state string returned exactly to the solved arrangement ✓ - Scramble: 22 moves executed sequentially with distinct intermediate states ✓ - Drag-orbit: camera moved from (4.68, 4.60, 6.45) to (0.65, 9.13, −0.89) with no cube state change ✓ - Reset: state returned to solved and camera back to (4.68, 4.60, 6.45) ✓ - Clean build re-tested: orbit drag + R + Reset with an error-free console ✓ **Not directly verified**: visual rendering quality (screenshots couldn't be viewed in this environment), wheel-zoom events (tool can't synthesize wheel; logic is clamped in code), and Shift-key inverse via keyboard (harness didn't deliver the modifier — inverses were verified through the R′ button instead).
