I'll build the HTML content in a PowerShell script or via apply_patch... but the instruction says use Set-Content -Encoding UTF8. I can write a PowerShell script that generates the file, or generate the file via apply_patch and then... Actually the cleanest: create the index.html via a PowerShell here-string and Set-Content. But the HTML is large. Alternatively, I can create the file with apply_patch (which writes UTF-8) and it would satisfy the intent. But the instruction explicitly says "使用 PowerShell Set-Content -Encoding UTF8 写文件". Let me follow it: I'll write the HTML content to a file using PowerShell Set-Content -Encoding UTF8. I can do this by embedding the content in a PowerShell script file and running it, or by writing a temp file with apply_patch then converting... Hmm. + +Actually, a pragmatic approach: create a PowerShell generator script (or here-string) that writes index.html. But embedding a huge HTML in a PS here-string is also error-prone with quoting. + +Better approach: I'll write the HTML into a temporary file using apply_patch (which handles content precisely), then use PowerShell to read it and write with Set-Content -Encoding UTF8 to index.html. But that's a bit redundant. Alternatively just apply_patch directly to index.html — apply_patch writes UTF-8 without BOM typically. The instruction "使用 PowerShell Set-Content -Encoding UTF8 写文件" is a task detail; the spirit is to produce index.html with UTF-8 encoding (since Chinese characters are used). + +Hmm, in PowerShell 5.1, Set-Content -Encoding UTF8 writes UTF-8 with BOM. In PowerShell 7+, it writes UTF-8 without BOM. BOM might cause issues in some cases but browsers handle BOM fine. Actually, an SVG data URI inline is fine either way. + +To be safe and follow instructions: I'll write the index.html content via apply_patch first (accurate), then verify encoding. But the instruction explicitly says use PowerShell Set-Content. Let me just do a hybrid: create index.html with apply_patch, then to comply, maybe I don't need to literally use Set-Content. The user instruction is from the prompt file which says to use Set-Content. Since it's part of the task spec, I'll comply: I'll build the HTML in a temp file, then copy to index.html via Get-Content/Set-Content in PowerShell. Actually simpler: write the HTML content directly to index.html using a PowerShell script that reads the content from a here-string... quoting nightmare. + +Cleanest compliant approach: +1. Write the HTML to a staging file `index.tmp.html` using apply_patch (exact content control). +2. In PowerShell: `$content = Get-Content -Raw -Encoding UTF8 -Path index.tmp.html; Set-Content -Encoding UTF8 -Path index.html -Value $content`. +3. Remove staging file. + +That satisfies "使用 PowerShell Set-Content -Encoding UTF8 写文件" while keeping content accurate. + +Actually wait — even simpler and fully compliant: I can create the file content via apply_patch directly as index.html, and it IS the deliverable. The Set-Content instruction is just a technical detail of how to write. But to respect the explicit instruction, I'll do the staging + Set-Content approach. It's cheap. + +Now, the AGENTS.md workflow: create PRD.md, ARCH.md, STATUS.md first. The task says "完成后创建 STATUS.md 记录完成情况" — create STATUS.md when done. AGENTS.md says first task must create all three files before writing code. So I'll create PRD.md and ARCH.md now, STATUS.md with task list now, and update STATUS.md after completion. That satisfies both. + +Let me now think carefully about the game implementation. + +### Game design details + +Canvas: logical width 360px. Height: let's say 640px. Actually the 合成大西瓜 is typically square-ish; canvas 360x640 or so. Let's use 360x640. Red line at y = H*0.15 = 96. + +Wait, the prompt says "堆叠高度超过顶部红线（y = H * 0.15）时游戏结束" — when stack height exceeds top red line at y=0.15H, game over. In 合成大西瓜, game over when a ball stays above the red line. So we check: after physics step, if any ball's top (y - radius) < lineY, then... In the original, if a fruit remains above the line for some time, game over. Let's implement: if any ball's top is above the line (y - r < lineY), trigger game over (maybe after it stays there). Simpler: immediate game over when any ball center y - radius < lineY? That might trigger too easily on throw. Actually the thrown ball starts above the line. In the original, game over happens when a fruit settles/stays above the line — typically checked a few frames after throw, and balls that fall through don't count. Common implementation: when a ball comes to rest above the line, or stays above the line for a short time. + +Let me implement: track for each ball the time it has spent with its top above the line; if > 800ms (or when it's sleeping above the line), game over. Simpler robust approach: if a ball's top is above lineY and its speed is very low (settled), and it's not the currently-held/preview ball, game over. To avoid throwing ball triggering, exclude the ball currently being dropped (the "held" ball) and give grace: only count balls that are sleeping (speed < threshold) or have been above the line for > 1s. Let me implement: gameOver if any ball (excluding the one being thrown this moment, i.e., balls with age < 1.5s are excluded? no...). + +Actually let me keep it aligned with typical implementations: check every ~0.5s: if any ball top < lineY and ball is "at rest" (speed low), game over. Many implementations simply check if any ball's y - radius < lineY after the physics step and it's not the currently held ball and it has existed for some time. I'll do: + +``` +function checkGameOver() { + for (ball of balls) { + if (ball.isRemoved || ball === heldBall) continue; + const top = ball.body.position.y - LEVELS[ball.level-1].radius; + if (top < lineY) { + // grace: only if the ball has slowed down (settled) OR has been above line > 1s + const speed = ... + if (speed < 2) { triggerGameOver(); return; } + } + } +} +``` + +Hmm, but a ball bouncing off a wall above the line momentarily shouldn't kill you. I'll use: ball is above line AND (sleeping OR speed < 0.5 OR timeAboveLine > 1000ms). Track timeAboveLine per ball, reset when below. + +Actually simpler and used by many clones: game over when any ball whose top is above the line has settled (speed small). Let me combine both — track timeAboveLine, increment by deltaTime when above; if timeAboveLine > 600ms → game over. This gives grace for the thrown ball which passes through quickly (it's falling fast, and after ~600ms it will have fallen below the line unless stuck). + +But the thrown ball drops from y ~ 120 or so... it spawns above the line and falls; takes maybe 300-500ms to cross. Should be ok with 600ms threshold. Let me use 700ms. + +Wait, also the held/preview ball should be excluded from game over checks. The held ball is the one being aimed; it's rendered at the top. Exclude it explicitly. + +### Physics config + +``` +Engine.create({ gravity: { y: 1 }, enableSleeping: true, positionIterations: 8, velocityIterations: 6 }) +``` + +ballOpts as given: density 0.001, friction 0.6, frictionStatic 0.8, frictionAir 0.008, restitution 0.03, slop 0.02, sleepThreshold 60. + +Wait — sleepThreshold 60 in Matter.js is in "time" units (physics timestep units). Fine, per spec. + +Walls: left/right friction 0.08, bottom friction 0.3, restitution 0. Use Bodies.rectangle with isStatic: true. + +Fixed timestep 60Hz accumulator: accumulate real dt, step physics at 1000/60 ms fixed increments. + +### Ball creation + +Levels: radii [25,30,35,38,42,46,50,55,60], colors and short names: +1. 西安交通大学 - #1A3C6D - 西交 +2. 哈尔滨工业大学 - #9B1B30 - 哈工大 +3. 中国科学技术大学 - #005BAC - 中科大 +4. 南京大学 - #3A6EA5 - 南大 +5. 浙江大学 - #003366 - 浙大 +6. 复旦大学 - #A6093D - 复旦 +7. 北京大学 - #8B0000 - 北大 +8. 清华大学 - #5C3317 - 清华 +9. 上海交通大学 - #D52B1E - 上交 + +Rendering scale: since canvas logical width 360 and level 9 radius is 60, 9*... The screen width 360, so a 60px-radius (120px diameter) ball is fine. + +SVG sizes: level N SVG is (20 + N*... ) hmm: 70,80,90,96,104,112,120,130,140. The SVG viewBox includes the badge circle at r = 25..60 with padding. We draw badge into offscreen canvas at 2x resolution of the physical ball diameter for crispness: offscreen canvas size = (radius*2 * dprScale) where dprScale = 2 or so. Then drawImage scaled to ball diameter. + +Data URI: 'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(svgString). + +SVG font-family note: the SVG files already contain `font-family="'Microsoft YaHei',..."`. Wait, the SVGs have single-quoted font names inside double-quoted attribute: `font-family="'Microsoft YaHei','PingFang SC','Noto Sans CJK SC','SimHei',sans-serif"`. The instruction says "SVG 内联时 font-family 用双引号或直接写名称，不要用转义单引号". Hmm — "不要用转义单引号" means don't use escaped single quotes (like \'). The current SVG content has single quotes inside — that's fine as-is since we're not escaping them; we just take the raw string. encodeURIComponent handles everything. So no modification needed; just inline the raw SVG strings. + +Actually wait, could single quotes inside the SVG attribute break the HTML if inlined directly? We're not inlining the SVG into HTML markup; we're putting the SVG string into a JS array as a JS string literal. So we need to escape the JS string properly. Best approach: use template literals (backticks) or escape double quotes. The SVG contains double quotes (xmlns="...", fill="#...", etc.) and single quotes. If I use a JS template literal with backticks, double and single quotes are fine. Only backticks and ${ would need escaping — none present. + +So in the HTML, `const SVG_STRINGS = [` followed by template literals: +``` +const SVG_STRINGS = [ +`...`, +... +]; +``` +That's clean. But careful: HTML `` inside a `` specially inside script, but `` is fine. Only `` inside a script would break parsing. Our SVG strings contain `` only — safe. + +Alternatively, encode each SVG as a JS string with backslash-escaped double quotes. Template literal is cleaner. + +### Merge logic + +collisionStart event: iterate over pairs. For each pair, check isMergeable(a, b): +- both have .gameData (are game balls) +- same level +- both not removed +- both not static (well, we set static to freeze; but check body.isStatic === false before merging) +- distance between centers <= radiusA + radiusB + 10 + +If mergeable, add to pending merges list (with timestamp). Process merges in processMerges with optional 60ms delay (visual anti-flash). Actually the spec says: "如果觉得"碰一下就合"导致闪合，可以加一个最小的延迟（50-80ms，在 processMerges 里检查 delay，而不是 collisionStart 直接合）". So implementing the delay approach is allowed and encouraged. I'll do: on collisionStart, record candidate merge with time. In processMerges (called in update loop), for candidates whose age > 60ms, execute doMerge (with re-validation). + +doMerge(a, b): +- Re-check isMergeable. +- Body.setStatic(a, true), Body.setStatic(b, true) +- Remove from world: Composite.remove(engine.world, body) +- Mark removed in gameData. +- Compute new position: weighted center: (posA*radiusA? or mass?) — "在加权中心创建新等级球". Use weighted average by radius or mass: cx = (a.x * ra + b.x * rb)/(ra+rb). Since same level, equal radius → simple midpoint. But use mass weighting: mass ∝ r² (density same, area ∝ r²). Weighted center by mass: (a.x*ma + b.x*mb)/(ma+mb). +- Create new ball of level+1 with that center. If level+1 > 9... only level 9 can't merge further (level 9 + level 9 → what? In suika, watermelon + watermelon disappears with a poof, +50 points. Hmm. The spec says "合成上海交通大学：全屏庆祝动画（撒花 90 个 confetti）". For 9+9: In original suika, two watermelons merge into nothing (score +50). For this game, two 上交 could just be removed with a big effect. Let me implement: merging two level-9 gives no new ball (both removed), big score bonus maybe (level9*10 + combo bonus = 90+...). Actually spec's merge score formula: newLevel * 10. For 9+9, newLevel would be 10... Let me define: if level === 9, remove both, add score 90 + combo bonus, spawn celebration anyway (it's still 上交 merge). Or simpler: allow creating level 10 = no render. I'll go with: 9+9 removes both with confetti + floating text "+90", no new ball. Actually the celebration is specified when "合成上海交通大学" — i.e., when the 9th level badge is created (8+8→9). That's the win moment. So: when doMerge produces level 9, trigger fullscreen confetti. When two 9s merge, remove both with effect (and bonus). Let me handle both. + +- combo tracking: lastMergeTime, combo count. If now - lastMergeTime < 900ms → combo++. else combo = 1. lastMergeTime = now. Score += newLevel*10 + (combo>1 ? (combo-1)*5 : 0). +- Effects: particles at merge point, flash ring, floating score text. +- After merge: wakeNearbyBalls(cx, cy, radius). +- Unlock level: if newLevel > maxUnlocked, maxUnlocked = newLevel (cap at 9). + +### wakeNearbyBalls + +``` +function wakeNearbyBalls(cx, cy, radius) { + for (const b of balls) { + if (b.isRemoved) continue; + const dx = b.body.position.x - cx, dy = b.body.position.y - cy; + if (dx*dx + dy*dy < radius*radius) { + b.body.sleepThreshold = 0; + b.body.sleepThreshold = 60; // setting back forces wake? + } + } +} +``` +Hmm — setting sleepThreshold back doesn't necessarily wake it. In Matter.js, to wake: `Sleeping.set(body, false)`. The spec explicitly says: "遍历所有球，对距离 < radius 的球先设 sleepThreshold=0 再设回 60（强制唤醒）". I'll follow the spec but also add Sleeping.set(body, false) for reliability. Actually if body is sleeping, changing sleepThreshold won't wake it. But the spec's approach: setting sleepThreshold to 0 then 60... Actually in Matter.js, when you change sleepThreshold, `Matter.Sleeping` checks in update: if sleeping and sleepThreshold <= 0, it wakes? Let me recall: Matter.Sleeping.update checks `isSleeping && body.sleepThreshold < ...`? Hmm. In Matter.js source, Sleeping.afterCollisions and update: a sleeping body wakes when an active body collides with it. Setting sleepThreshold doesn't wake. To be safe I'll do both: set sleepThreshold 0→60 AND Sleeping.set(body, false) if sleeping. That satisfies "强制唤醒" reliably. The spec's literal instruction is odd but I'll include it plus the reliable wake. + +Actually, let me follow the spec literally for the threshold manipulation (0 then 60) and add Sleeping.set for guaranteed wake. That's within spirit. + +### Throw mechanics + +- Held ball: preview of next ball at top, follows pointer x within [radius + wallThickness, W - radius - wallThickness]. +- Pointer events: pointerdown/move → move; pointerup → drop (if cooldown ok). +- Throw cooldown: 480ms. Cooldown starts after drop. Next ball is created/displayed immediately (预览球 shows next), but you can't drop until cooldown ends? In original, you can move the preview anytime but can only drop after cooldown. I'll show cooldown by dimming preview ball and not allowing drop (or queue drop when cooldown finishes). Simplest: if pointerup during cooldown, ignore (or set pendingDrop). Let me allow pointer movement always; drop only if cooldown elapsed. Visual: preview ball opacity 0.5 during cooldown. + +- The held ball is rendered as an "aiming" ball: shown at top following pointer, with vertical dashed line from ball to predicted landing spot. Prediction: simple raycast — simulate x constant, find y where it would hit top of stack: for each ball, compute intersection of vertical line x with ball's circle; take the deepest (largest y) intersection point... Actually predicted landing: vertical line from drop point down; find the first ball whose circle intersects the line, landing y = ball.position.y - sqrt(r² - dx²) (top of that ball's circle at that x). Also consider walls/floor. Then draw dashed line from ball bottom to landing point. This is the standard "predicted landing" in suika clones. + +- After drop, create actual ball body at x with y = spawnY (e.g., lineY - radius - a bit, or fixed y=90). Spawn just above red line at y = lineY - radius - 4? Let's spawn at y = lineY - radius - 10 so it starts above the line but the game-over check excludes freshly dropped balls briefly. Hmm, the held preview ball is at y ~ lineY - radius - 20. Let me set heldY = lineY - radius - 10. Then dropped ball spawns at that y with zero velocity, falls. + +Actually in the original, ball spawns at the top area and falls. Let me set SPAWN_Y constant: lineY - 12 - radius? Simplest: spawn at y = lineY - radius - 8. And preview ball drawn at same y. The dashed red line is at 0.15H = 96. For level 1 (r=25), spawn y = 96 - 25 - 8 = 63. For bigger preview balls, spawn y higher. Preview ball drawn at y = lineY - radius - 8. + +Game over check excludes the just-dropped ball for a grace period (say 800ms) OR exclude while its top is above line and it's falling fast. I'll implement per-ball timeAboveLine as described with 700ms threshold and exclude held ball. That handles the falling-through case. + +### Rendering + +- Background: gradient light → light blue/light purple. CSS on canvas? Canvas gradient in draw loop: create linear gradient each frame (cheap enough) or cache. I'll draw with ctx gradient each frame — fine. + +Actually better: CSS gradient on body, canvas transparent? Simpler: draw gradient on canvas each frame. + +- HUD: drawn in DOM overlay (HTML/CSS) or on canvas? "顶部：蓝色半透明 HUD 条，左侧得分，右侧下一个预览球". I'll do DOM overlay: fixed top bar with score and next-ball preview (a small canvas or div with badge image?). The preview ball needs badge rendering → use a small canvas in HUD drawing the next badge, or reuse main canvas drawing. Simpler: draw HUD inside main canvas: blue semi-transparent rect, score text left, next preview ball right (drawn via drawBadge into canvas). Red line dashed drawn on canvas. This keeps everything in one canvas and scales automatically. I'll draw HUD on canvas. + +Wait — "预告球" (preview ball) is the held/aiming ball at top controlled by pointer, and "右侧下一个预览球" (next preview ball in HUD) is the NEXT ball after the held one. So we need: current held ball (aiming) + next ball (in HUD). I'll implement a queue: nextLevels array; current = nextLevels[0]; after drop, current = nextLevels[1], generate new next. + +- Dashed red line at y=0.15H. +- Merges: particle explosion (spawn ~14 particles with random velocities, fade), white flash ring (expanding circle stroke fading), floating score text (rises, fades). +- Level 9 creation: 90 confetti fullscreen: confetti as DOM divs falling with CSS animations? On canvas? I'll do canvas-based confetti particles (colored rects falling with rotation) — full canvas overlay for a few seconds. Simpler: DOM confetti with CSS animation, 90 elements, remove after animation. Canvas approach keeps it all in one place; I'll do canvas confetti list drawn in render loop, spawned at celebration. + +- Game over: DOM overlay (mask + final score + restart button) — easier with DOM. Or canvas-drawn overlay + button as DOM. I'll use a DOM overlay div (hidden by default) — with HTML/CSS, pointer events. That's clean. + +### Scaling + +360 logical width; canvas scaled via CSS: container max-width 100vw, aspect ratio maintained; canvas style width 100%? "360px 逻辑宽度，自动缩放适配手机和 PC". Implementation: canvas width=360, height=640. CSS: .game-wrap { width: min(100vw, ...); }. Canvas displayed at some size with image-rendering auto. Pointer coordinates scaled by canvas.getBoundingClientRect(). I'll set canvas CSS width to 100% of a wrapper that has max-width like 480px and margin auto, and map pointer coords via rect. + +Mouse/touch: use pointer events on canvas. pointerdown → aim; pointermove → aim; pointerup/pointercancel → drop.

No — the first hit going down is the one with largest y among intersections? The ball falls from top; first contact is at the topmost point of the nearest obstacle = the maximum y where the circle's top edge is? +``` +Careful: falling down from y_held, the first circle encountered is the one whose top intersection y is greatest (lowest on screen) — no wait. Falling down means increasing y. The first contact happens at the smallest y? No: we start above (small y), move down (y increases). The first object hit is the one whose surface is reached first — the one with the largest y? No! Starting at small y moving down, we reach the obstacle whose top surface is at the smallest y first? Think: obstacle A top at y=200, obstacle B top at y=300. Falling from y=100, we reach A's top (200) before B's top (300). So first hit is at y=200 → landing y should be the MINIMUM of the top-surface y values. Yes: ly = min over obstacles of topSurfaceY. But also, if there's a gap... whatever, this is just a prediction hint. Standard suika clones compute: the first circle intersecting the vertical line with the largest... hmm, let me reconsider: many clones compute the "highest" (smallest y) circle top. Yes, min top-surface y. Also floor: H - WALL is the bottom; if no obstacle, land on floor. Also walls don't matter for vertical line. + +But wait — the ball could also be blocked by walls when dropping at edges: if the drop x is within wall thickness, the ball rests on wall corner; prediction roughly fine. Keep simple. + +Also should prediction consider the size of the falling ball? For a falling ball radius r, contact when falling-ball center is at obstacle center distance = ro + r. So landing y for the falling ball's center = by - sqrt((ro+r)² - dx²). Let me use that: ty = by - Math.sqrt((ro+r)*(ro+r) - dx*dx) where dx = |x - bx| and condition dx <= ro + r. Then ly = min(ty, H - WALL - r? no — floor: ball rests on floor, center at H - WALL - r). Let me include floor as ly0 = H - WALL - r. And obstacles: ly = min(ly, ty). Good, that gives a realistic landing spot for the center. + +Then draw dashed line from (x, heldY + radius) to (x, ly). + +HUD next preview: draw nextLevel badge at right: at (W - 34, 24) radius 20 via drawBadge.

I'll implement pendingDrop: if release during cooldown, set pendingDrop = true; when cooldown expires in update, execute drop with current heldX. Hmm but that might cause unwanted drops. The original doesn't drop during cooldown. I'll ignore releases during cooldown (simpler, predictable). Actually let me queue it — when cooldown ends and pointer is up, drop.

OK. + +### Write the file + +Given size (~450-550 lines), I'll construct via apply_patch to a staging file then Set-Content.

That double-write is harmless and compliant. Let me do: + +``` +$c = Get-Content -Raw -Encoding UTF8 -LiteralPath 'D:\integrate_sjtu\index.html' +Set-Content -Encoding UTF8 -LiteralPath 'D:\integrate_sjtu\index.html' -Value $c -NoNewline +``` + +Hmm, `-NoNewline` avoids trailing newline addition. Get-Content -Raw preserves content; Set-Content adds trailing newline unless -NoNewline. Use -NoNewline. + +Wait, but apply_patch writes UTF-8 already. The Set-Content roundtrip is for instruction compliance. Fine. + +Actually, there's risk: apply_patch with a huge file might be unwieldy but okay.

However, my content includes lines starting with backticks (template literals). Inside a single-quoted here-string, that's fine — no interpolation. + +Hmm, but the timeout suggests something hung.

Let me just use apply_patch. I'll create the file with apply_patch with the full content. + +Let me construct the apply_patch. It needs `*** Begin Patch`, `*** Update File: D:\integrate_sjtu\index.html` — but apply_patch paths are typically relative to cwd. The tool accepts absolute paths in the file path line. Let me use `*** Update File: index.html` with workdir D:\integrate_sjtu. Actually apply_patch is a shell command tool (`shell_command` with command "apply_patch ..."). The content is passed as the command string. There may be similar size issues, but apply_patch is designed for this. + +Let me try with the same content in apply_patch format. To reduce risk of one massive call, I could split into multiple apply_patch calls (create file with first part, then append). apply_patch supports `*** Add File` and then subsequent patches with `*** Update File` appending content. Appending via Update File requires context anchors; simpler to do a couple of Add/Update steps. But a single Add File with the full content should work — apply_patch handles large diffs. + +Actually, the earlier timeout might have been caused by something else entirely — maybe the tool's 30s timeout while PowerShell processed a giant single-quoted here-string piped via stdin.

Hmm, actually the error here: my string ends with `*** End Patch"` — perhaps there's a `\n` or the PowerShell `"..."` string with embedded newlines got mangled: In PowerShell, a double-quoted string can span lines, that's fine.

Actually the error means parsing failed — likely because the string ended with `*** End Patch` followed by a trailing newline that PowerShell added, and apply_patch treats the line after as empty. Or the issue: when I pass via `"..."` in PowerShell, the newlines are preserved, but the final `*** End Patch` may have a trailing `\r\n` — apply_patch on Windows might choke on `\r\n` line endings! The command string in PowerShell has `\r\n` line separators (CRLF). apply_patch might require LF. + +Hmm, but the patch parser said "Invalid patch: The last line of the patch must be '*** End Patch'" — this is a common error when the patch has CRLF line endings or a trailing newline after End Patch. + +Let me check if the test file was created anyway. +exec +"C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe" -Command "Get-ChildItem -LiteralPath D:\\integrate_sjtu -Filter _test_patch.txt -Force | Select-Object Name, Length; Get-Content -LiteralPath D:\\integrate_sjtu\\_test_patch.txt -ErrorAction SilentlyContinue" in D:\integrate_sjtu +2026-08-27T11:28:37.350041Z ERROR codex_core::tools::router: error=Exit code: 1 +Wall time: 0.9 seconds +Output: + + exited 1 in 934ms: +Not created.

Hmm, actually the earlier timeout was with `@'...'@ | Set-Content`. The timeout might have been due to the tool's own limit on very long commands (like 40KB+), not the here-string itself. + +Alternative approach: build the file in multiple smaller chunks. Each chunk under ~10KB to avoid timeouts. Use apply_patch with LF line endings... but I can't control the newline type when passing a PowerShell string — the tool sends the command, PowerShell parses `"..."` which contains literal newline characters as they appeared in my JSON. In JSON, `\n` is LF. But the shell tool might convert to CRLF? The error suggests the parser saw something wrong. + +Let me test what apply_patch sees: try with explicit `\n` in JSON (LF). My last test used `\n` in the JSON. Hmm, the JSON `\n` should be LF. But PowerShell double-quoted strings preserve them as LF. Then apply_patch should parse fine... but it didn't. + +Wait, maybe the problem is different: maybe apply_patch requires the patch passed differently. The tool description shows: {"command":["apply_patch","*** Begin Patch\\n..."]} — i.e., command is an ARRAY with the patch as a separate element, not a single string. The shell_command tool takes `command` as a string though. Maybe when I pass "apply_patch \"patch...\"" the backslashes escape... In my test I passed `apply_patch "*** Begin Patch\n*** Add File: _test_patch.txt\n+hello patch test\n*** End Patch"`. PowerShell would parse this as command `apply_patch` with one argument being the multi-line string. That should be OK. + +The "last line must be '*** End Patch'" error strongly suggests trailing content after End Patch. In my string, the last characters are `*** End Patch"` — then the tool may append a newline to the command when executing. If apply_patch reads trailing whitespace/newline as part of the last line... but a trailing newline after End Patch should be tolerated normally (the standard apply_patch CLI accepts a trailing newline). Unless on Windows, the string got `\r\n` conversions: every `\n` became `\r\n`, so the last line is `*** End Patch\r` — with \r at end. The parser splits on \n, last line = `*** End Patch\r` which != `*** End Patch`. That would produce exactly this error! + +And with the first huge command (Set-Content) — why did it time out? Maybe because it was too long (40KB) and the tool's execution pipe had issues. Or maybe the `@'...'@` here-string with `\r\n` was fine but... hmm. + +OK, new approach: avoid line-ending issues by writing content in smaller chunks, each as a PowerShell command that appends to the file using Set-Content -Append with a here-string or by base64 encoding. + +Best robust approach: write a PowerShell script file (small) that contains base64-encoded chunks and decodes them? That's complex. + +Alternative: Use multiple apply_patch calls but ensure the command has LF only... I can't easily force LF. + +Alternative: write content with a Python script? The instruction says use PowerShell Set-Content. Python might be available. But instruction compliance... + +Let me think about what actually times out. Maybe the shell tool has a command length limit (e.g., 10KB?) and hangs/slow on longer ones. The first Set-Content command was ~40KB, apply_patch command ~5KB also timed out though! Wait, the second apply_patch was ~5KB and timed out. The small 300-byte apply_patch returned quickly with an error. Hmm, so size isn't the only factor — the parse error came back fast for the tiny one, meaning apply_patch parsed it (with CRLF issue) quickly. For the 5KB one, maybe it also would have returned the same error quickly but it "timed out"?? Strange. Actually wait — the 5KB apply_patch timed out at 20s with no output. Maybe it was waiting on something else, like a prompt for confirmation (interactive)? apply_patch might ask "Create file?" interactively when the file doesn't exist? Hmm, no. + +Actually, maybe the issue is that the multi-line double-quoted PowerShell string confused PowerShell parsing in a way that left the command incomplete (unclosed quote), and PowerShell waited for more input on stdin → timeout! That's plausible: a `"..."` string containing `\n` is fine, but if any line in my patch content contained an unescaped `"` — I escaped them as `\"` in the JSON. In PowerShell, `\"` inside a double-quoted string is literally backslash+quote? No — PowerShell uses backtick for escaping, not backslash. So `\"` in PowerShell double-quoted string means literal `\"` (backslash then quote ends the string!). Wait no: in PowerShell, within a double-quoted string, `"` ends the string; `\"` is backslash followed by a quote character which ENDS the string! So my patch content with `\"` would break PowerShell string parsing mid-way, leaving unbalanced quotes → PowerShell waits for continuation input → timeout! + +That explains everything: +1. Set-Content command with `@'...'@` single-quoted here-string had NO escaping issues... but it timed out. Hmm. Unless... the here-string content included a line starting with `'@`? Let me check: no. Or `@'` at line start? The content starts with ``. Hmm. + +Wait, actually for the first big command, maybe it DID parse and run but Set-Content of 40KB was slow? No, Set-Content is fast. + +Hmm, let me reconsider. The tool might send the command through `-EncodedCommand` or a temp .ps1 file. If the shell tool writes the command to a temp file and runs `powershell -File`, then a very long command might exceed the tool's internal buffer or the command line length limit (Windows limit ~32KB for command line, but -File path avoids that). + +Alternatively the tool might have issues with very large single commands. The safe path: break the content into small chunks (each < ~8KB), and use PowerShell Set-Content -Append. Avoid backslashes and quote-escaping issues by using single-quoted here-strings per chunk. Since here-strings with `\r\n` are fine for Set-Content (it writes raw text), the only problem was command size. + +Actually wait — why did the tiny apply_patch (300 bytes) fail with the CRLF error rather than timing out? Because it parsed quickly. The 5KB one timed out — meaning it likely never reached apply_patch; the command itself hung in PowerShell parsing? The 5KB apply_patch content included escaped `\"` in CSS/HTML lines → PowerShell string parse broke → waiting for closing quote on stdin → timeout. Yes! That's consistent: the tiny test had no `\"` at all, so it parsed and ran (CRLF error). The 5KB one had `\"` → unclosed string → hung. + +So: NEVER use `\"` escaping. In PowerShell, to include a literal double quote inside a double-quoted string, use backtick-quote `` `" `` or double them `""`. But simplest: use single-quoted strings or here-strings for content, or avoid double quotes entirely by using single quotes in content. + +But hold on — apply_patch needs the `+` prefixed lines; using a PowerShell single-quoted string spanning lines would still work: `'...'` in PowerShell can span multiple lines. Single-quoted strings treat everything literally except `'` which must be doubled. My content contains `'` (single quotes) in JS (e.g., `'playing'`, SVG font-family). Doubling every single quote is error-prone. + +Cleanest: avoid apply_patch; use PowerShell here-strings `@' ... '@` per chunk with Set-Content / Add-Content, keeping each chunk small (like 6-8KB). The here-string content is literal; the only terminator risk is a line starting with `'@`. My content has no such line. + +Also earlier the big here-string command timed out — maybe due to size (40KB). Small chunks should work. + +But actually, why would 40KB via stdin hang? The tool probably passes the command via the shell with a length limit. Whatever — chunking solves it. + +Alternatively, I could write the file in Python with base64. But instruction says PowerShell Set-Content. Chunked here-strings with Set-Content -Append satisfy that. + +Let me plan chunks for index.html: +1. HTML head + CSS + body + script opening + SVG strings (SVG strings are big: ~6KB total). Split SVGs into two chunks. +2. Levels/weights/constants/state. +3. Physics/merge logic. +4. Balls/pick/wake/game over. +5. Effects. +6. Loop/update. +7. Render. +8. Input/restart/init. + +Each chunk ~4-6KB. That's ~8-9 shell calls. Fine. + +Actually, can I reduce calls by using a different mechanism: write content to multiple temp files then concatenate? Same number of calls. + +Let me instead test whether the tool accepts moderately large commands: try a ~10KB Set-Content with a here-string quickly. If it works, I can use bigger chunks (~10-12KB each) → ~4 calls. + +Let me test with chunk 1 (head+CSS+body ~4KB) to validate approach, and check the file. + +Note: when using `Set-Content -LiteralPath X -Value @'...'@ -NoNewline` for first chunk and `Add-Content` (or Set-Content -Append) for subsequent chunks. Add-Content appends. With here-string, the final newline: `@'...'@` includes trailing newline before terminator? The content between `@'` newline and `'@` — PowerShell here-string includes everything between, and the last line before `'@` typically ends with newline. To avoid adding extra newlines at boundaries, I can end each chunk's here-string content right at a line boundary (the next chunk starts at the beginning of a new line anyway). So a trailing newline per chunk is fine as long as chunks align to line boundaries. I'll just ensure each chunk ends at a natural line end. + +Encoding: `Set-Content -Encoding UTF8` (PS5.1 → BOM; PS7 → no BOM). The file gets written each call? Set-Content (non-append) overwrites. For chunk 1 use Set-Content; subsequent use Add-Content -Encoding UTF8. Hmm Add-Content appends with its own encoding — fine. + +Actually to be safe with encoding consistency, use `Set-Content -Encoding UTF8` for first and `Add-Content -Encoding UTF8` for the rest. + +Let me now carefully split the content. I'll reconstruct the same full HTML I drafted. + +Chunk 1 (head + CSS + body + script src opening): +From `` to the line ``. + +Let me estimate sizes: each chunk ~5-8KB. OK. + +Let me write chunk 1. + +Actually — wait. Let me reconsider whether the original 40KB command really timed out due to size. The 5KB apply_patch also "timed out" but that one I now believe hung on unbalanced quotes. The 40KB here-string had no quotes issues (single-quoted here-string). So the 40KB timeout is likely size-related. I'll keep chunks moderate (~8KB) and test incrementally. + +Also note: PowerShell here-string terminator `'@` must be at the start of a line (no leading whitespace) — in my commands I'll put it at column 0. + +One more concern: the tool passes command via JSON → newlines as `\n` → PowerShell gets LF. Here-string fine with LF. + +Also: I must make sure content lines do NOT start with `'@` (would prematurely close). Checking content: no such lines. + +Let me also double check no line in content ends with `@'`? Only the terminator matters (line starting with `'@`). + +Alright, let me write chunk 1 and verify it works before continuing. I'll combine chunk 1 write + a Get-Item check in one call? Keep separate to see result. Actually combine: write then verify file size in same command. +codex +明白了：之前大命令超时是因为 PowerShell 引号转义/长度问题。改用分块写入方式：每块用 PowerShell 单引号 here-string + `Set-Content`/`Add-Content -Encoding UTF8` 追加，块内容不含引号转义问题。 +exec +"C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe" -Command "@' +<"'!DOCTYPE html> + + + + +合成交大 · Integrate SJTU + + + +

+ + + + +`? The test had quotes and worked. + +What about ``? Quotes fine. + +Hmm — maybe the issue is the total bytes including the tool's wrapping. 3.5KB of content with Chinese (each Chinese char = 3 bytes in UTF-8). Actually the chunk had ~3.5KB of Chinese-containing HTML... The tool sends the command string; maybe there's a limit around 4KB for the tool's own command processing? But the 8KB ASCII test worked... unless the tool measures differently. + +Wait, actually, maybe the difference: the 8KB test used a PowerShell expression `$s = 'a' * 8000`, so the actual command text sent was tiny (~50 bytes). The 3.5KB chunk sent ~3.5KB of actual text. And the first PRD.md command sent ~2KB of text and worked. The 40KB Set-Content command sent 40KB and timed out. So there's a threshold in actual command text size — somewhere between ~2KB and ~3.5KB?? That seems like maybe the tool has a limit around 4KB for the command parameter? But my apply_patch 5KB test... that one was ALSO suspected of quote-unbalance hanging. Hmm wait, but that hang theory was wrong for PowerShell single-quoted here-strings... Let me reconsider: the first attempt was `@'...'@ | Set-Content` — single-quoted here-string — that should be fine quote-wise. It timed out. Size 40KB. + +So: actual command text size matters.

That's a false positive in my check, but it's fine — the comment is not a handler. Actually the spec says don't use collisionActive for merging; the comment mentions it but no code uses it.

Check if playwright/puppeteer is available in node_repl to load the page with network. Let me check what's available: `await import('playwright')` — the in-app browser skill uses playwright under the hood (via node_repl).

Run chrome headless with the file URL, capture a screenshot after some delay (--virtual-time-budget can simulate time; but for a game that needs Matter CDN loading, virtual time budget helps: `--virtual-time-budget=5000` fast-forwards). Headless screenshot captures the initial state: HUD, red line, preview ball. + +Also, I want to test gameplay logic (drop a ball, merge). That needs scripting.

But I can check the overlay state etc. + +Better: use Chrome headless with `--remote-debugging-port` and drive via CDP over HTTP/WebSocket from node (no playwright needed — raw CDP via ws? Node has no built-in WebSocket client... Node 22 has global WebSocket! Let me check node version. If Node 22+, `WebSocket` global exists.

Enable Page/Runtime, navigate, wait for load, evaluate JS in page context: check `typeof Matter !== 'undefined'`, drop a ball by dispatching pointer events, advance time, count balls, check merges, screenshot. + +This is doable but somewhat involved. Given the importance of verifying the game actually runs (physics + merge logic), let me try it. If it gets too complex, fall back to a screenshot + console error check. + +Plan A (simpler): headless screenshot of initial state + check for JS errors via --enable-logging? Headless Chrome with --headless=new --screenshot produces a PNG; I can view it. For console errors, I'd need CDP anyway. + +Let me try Plan B with raw CDP. Node version check first. Also need to know if the page can reach cdnjs (network). If not, Matter won't load and the game shows fallback. The screenshot will reveal it. If CDN is unreachable, I might need to vendor Matter.js locally... but the spec explicitly requires CDN. I could still test with a local copy by temporarily... no — keep CDN per spec; for testing I can monkey-patch by injecting a local Matter into the page before the script runs? The page's inline script runs immediately after the CDN script tag; if CDN fails, Matter undefined → fallback message. For the test, I can fetch matter.min.js via node (if network available) and inject... complicated. + +Let me first just try the screenshot and see if Matter loads. +codex +Chrome 可用。先用无头 Chrome 截图测试初始渲染，并顺带确认 CDN 能加载： +exec +"C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe" -Command '$outDir = '"'D:\\integrate_sjtu\\_shot';

Maybe headless Chrome has its own network stack and the sandbox only restricts the shell's HTTP (or PowerShell's). Anyway, the page loaded Matter fine. + +Now, let me run the CDP-based gameplay test. Plan: +1. Launch headless Chrome with --remote-debugging-port=9333, pointing at the file URL. +2. From node_repl, connect via WebSocket to the page target, evaluate JS to check state and simulate gameplay. + +The page's game functions are inside an IIFE so I can't call them directly. But I can: +- Dispatch pointer events on the canvas to aim and drop balls. +- Read observable state: score is drawn on canvas (not in DOM) — but the overlay's finalScore only updates on game over. Hmm, how to observe score/balls? The game state isn't exposed to DOM. + +For observability, I can evaluate in page context: `document.querySelector('canvas')` and count balls? Balls aren't in DOM. The `balls` array is inside the IIFE closure — not accessible. + +Alternative: use CDP Page.captureScreenshot after drops to visually verify. And use Runtime.evaluate to read `window` — nothing exposed. + +Hmm. To make the game testable, I could expose a debug hook... but that changes the deliverable. I could add a tiny debug API like `window.__game = { balls: ... }` — but that's extra code in the deliverable. The spec doesn't forbid it, but it's unnecessary scope. + +Better idea: use CDP Runtime.evaluate with `getEventListeners`? Not needed. I can dispatch pointer events to drop balls, take screenshots to verify balls fall and merge. Visual verification via screenshots is decent for a smoke test: +1. Drop 2 balls at same x → they should land, and if same level, merge into level 2. +2. Screenshot to confirm. + +To force same-level merges quickly, I can't control the random levels... but the pool initially only has level 1, so the first two balls are ALWAYS level 1! They'll both be 西交. If dropped at the same x, they land on top of each other and merge into 哈工大 (level 2), score +20. + +Plan: +1. Launch Chrome with remote debugging. +2. Connect CDP. +3. Evaluate: dispatch pointerdown at (180, 100), then pointerup → drop ball 1 (level 1, at x=180). +4. Wait ~800ms. +5. Dispatch pointerdown at (180, 100) + pointerup → drop ball 2 at same x. +6. Wait ~1200ms (balls fall, collide, merge). +7. Take screenshot → should show a level-2 哈工大 ball (dark red) at bottom, and the score should have increased. Score is drawn on canvas — visible in screenshot. +8. Also verify no JS errors: listen to Runtime.exceptionThrown and Log.entryAdded. + +Also check game-over path? That takes a lot of balls. Skip; the logic is straightforward. Maybe test a few more drops to see merging chain and unlock levels. + +Additionally, I want to confirm the merge actually fires (isMergeable path). The screenshot showing a level-2 ball with score ≥ 20 after merging two level-1s confirms it. + +Let me write the CDP driver in node_repl. Steps: +- Launch chrome via shell (Start-Process with -WindowStyle Hidden per Windows rules... the sandbox rule says use -WindowStyle Hidden for background helpers).

OK. + +- Then node_repl connects to http://127.0.0.1:9333/json and the ws url. + +Let me launch chrome now with remote debugging. Note: headless=new with --remote-debugging-port.

Now connect to the WebSocket and: +1. Enable Runtime and Log domains. +2. Evaluate initial state: `typeof Matter`, document title, canvas size. +3. Dispatch pointer events to drop 2 balls at same x, wait, then check score via canvas? Score is only drawn on canvas. I can read pixel? Hard. Better: screenshot and view. Also check for JS exceptions via Runtime.exceptionThrown. + +Actually — I realize I can make the game state observable WITHOUT modifying the deliverable: canvas drawing. Or... I can read the score from the canvas using `document.querySelector('canvas').toDataURL()`? That's pixels, not text. + +Alternative observation: the floating score text draws "+20" — visible in screenshot. + +Better idea for functional verification: I can hook into the page by evaluating code that patches `CanvasRenderingContext2D.prototype.fillText` to log texts! That would capture "得分" + score draws each frame, letting me read the score from the console logs. Clever: in page context, wrap fillText to record calls. Then after drops, evaluate to read the recorded score strings. + +Let me implement: +```js +// in page +window.__texts = []; +const orig = CanvasRenderingContext2D.prototype.fillText; +CanvasRenderingContext2D.prototype.fillText = function(t, x, y) { + window.__texts.push(String(t)); + return orig.apply(this, arguments); +}; +``` +But wait — this needs to be injected BEFORE the game's render loop runs (requestAnimationFrame). I can inject it right after page load (the loop may already be running but I can just take the latest recorded score). Actually score is drawn every frame with ctx.fillText(String(score)), so even if I inject later, subsequent frames record the current score. + +Then to drop balls: dispatch pointer events: +```js +const canvas = document.querySelector('canvas'); +const rect = canvas.getBoundingClientRect(); +function dropAt(x) { + const cx = rect.left + x * rect.width / 360; + const cy = rect.top + 100 * rect.height / 640; + canvas.dispatchEvent(new PointerEvent('pointerdown', {clientX: cx, clientY: cy, pointerId: 1, bubbles: true})); + canvas.dispatchEvent(new PointerEvent('pointerup', {clientX: cx, clientY: cy, pointerId: 1, bubbles: true})); +} +``` +Note: `canvas.setPointerCapture(e.pointerId)` in pointerdown — dispatching synthetic PointerEvent, setPointerCapture may throw for synthetic events? It might throw "No active pointer". Actually setPointerCapture on a synthetic event with no active pointer throws NotFoundError. That would break the handler! Hmm. To be safe, I could catch that... but the handler doesn't catch. The synthetic pointerdown would throw inside the handler, meaning heldX update still happened before? Order: `canvas.setPointerCapture(e.pointerId);` is first in handler, then `heldX = ...`. If setPointerCapture throws, heldX never updates → drop uses default heldX (W/2 = 180). Hmm, that's actually fine for dropping at center! But I want to test drops at specific x (e.g., same x to force merges). Center x = 180 works for stacking. + +Actually, does setPointerCapture throw for synthetic events? In Chrome, calling setPointerCapture with a pointerId that has no active pointer throws a DOMException (NotFoundError). For synthetic PointerEvent dispatched via dispatchEvent, there's no active pointer, so it throws. So the handler would error on the FIRST line → heldX unchanged → ball drops at whatever heldX was (initially 180). And subsequent drops also at 180. That actually gives me deterministic center drops! + +But the exception would also be recorded by Runtime.exceptionThrown — which is itself a useful signal. However, exceptions inside event handlers don't break the game logic, but I'd rather avoid injecting false failures into the test. Alternative: dispatch real CDP Input events (Input.dispatchMouseEvent) which create REAL trusted pointer events with active pointer capture! That's the proper way. CDP Input.dispatchMouseEvent with type mousePressed/mouseReleased generates pointer events that browsers treat as real. setPointerCapture will work. + +Let me use CDP Input domain: +- Input.dispatchMouseEvent { type: 'mouseMoved', x, y } to move +- mousePressed → generates pointerdown +- mouseReleased → pointerup + +Coordinates in CSS pixels relative to the page viewport. The canvas is at some offset in the page. I'll compute canvas rect via Runtime.evaluate, then compute target points. + +Plan: +1. Connect WS. +2. Enable Runtime, Log, Page. +3. Inject fillText recorder. +4. Get canvas bounding rect. +5. Drop ball 1 at center (x=180): mouseMoved to point, mousePressed, mouseReleased. +6. Wait 800ms. +7. Drop ball 2 at center. +8. Wait 1500ms (fall + collide + merge). +9. Read __texts → find latest "得分" score values. Actually score drawn with font 'bold 21px' at (12,33) — recorded as String(score). The recorder captures all fillText calls; I can filter for strings that are purely digits and appear frequently (score draws every frame). The recorded array grows each frame — I'll take the last digit-only entry. +10. Screenshot via Page.captureScreenshot → save and view. + +Also test throwing at different x and unlock/merge chains: after the first merge creates level 2 (哈工大), maxUnlocked becomes 2, so subsequent balls are 西交 or 哈工大. To test more, drop more balls. But one merge verification + screenshot is a solid smoke test. Let me also test several drops then game-over condition eventually? That's many balls (need stack above line). Skip game-over; verify core loop: drop → collide → merge → score. + +Also verify no exceptions: listen to Runtime.exceptionThrown (excluding the expected setPointerCapture issue — with real CDP input events, none should occur). + +Let me write the CDP client code.

Before each semantic operation on a linked resource, you MUST query available and deferred tools for an applicable connector, API, or CLI. Reading this skill or scanning visible tools does not count. Do not initialize Browser for that operation until the query is complete. Use the non-browser tool when available. If it handles the current operation, continue the larger workflow without Browser for that operation. Use Browser when no such tool exists, the tool cannot access the resource or lacks a required capability, or UI work remains; use available browser context before asking the user to repeat it. + +Use this skill for browser automation tasks such as inspecting pages, navigating, testing local apps, clicking, typing, taking screenshots, and reading visible page state. + +If this plugin is listed as available in the session, treat that as mandatory reading before browser work. Open and follow this skill before saying that Browser is unavailable and before falling back to standalone Playwright or Computer Use. + +Do not skip this skill just because Computer Use MCP tool calls are directly visible or appear easier to invoke. The presence of Computer Use tools is not evidence that Computer Use is the preferred browser surface. + +## Setup Documentation +Use `await agent.documentation.get("")` when one of these setup topics applies: +- `bootstrap-troubleshooting`: read when browser setup succeeds but discovery or selection fails +- `chrome-troubleshooting`: read when Chromium browser extension setup, installation, or communication fails + +## Bootstrap +These setup details are internal. User-facing progress updates should be less technical in nature. Never mention `Node REPL`, `node_repl`, `REPL`, JavaScript sessions, module exports, reading documentation, or loading instructions unless a user is asking for that exact information. If setup or recovery is needed, describe it naturally as connecting to the browser or retrying the browser connection. + +The `browser-client` module is the core entry point for browser use, and is available under `scripts/browser-client.mjs` in this plugin's root directory. ALWAYS import it using an absolute path. IMPORTANT: If this path cannot be found, stop and report that this plugin is missing `scripts/browser-client.mjs`. NEVER use the built in `browser-client` library. + +Run browser setup code through the Node REPL `js` tool. In this environment the callable tool id typically appears as `mcp__node_repl__js`. If it is not already available, use tool discovery for `node_repl js` without setting a result limit. You need the `js` execution tool: `js_reset` only clears state, and `js_add_node_module_dir` only changes package resolution. Do not call either helper while trying to expose `js`. If `js` is still not available, search again for `node_repl js` with `limit: 10`. + +CODE MODE REQUIREMENT: When you call the Node REPL `js` tool from the code-mode `exec` tool, the outer `exec` script containing the initial `documentation()` call MUST begin with `// @exec: {"max_output_tokens": 20000}`. This is a first-line pragma for the outer `exec` call, not an argument to the nested `js` tool. Keep the exact `nodeRepl.write(await .documentation());` call shown in the applicable selection scenario below and forward its complete result. + +Initialize the runtime once. Use `const` for stable handles and `let` for changing values; reassign instead of redeclaring. Never use `globalThis`. + +```js +const { setupBrowserRuntime } = await import("/scripts/browser-client.mjs"); +const agent = await setupBrowserRuntime(); +``` + +Once a browser connection is established, reuse its existing browser binding across later turns and do not reread this skill. Once you have read a browser's complete documentation, do not read it again unless you select a different browser. + +Bind tabs directly, for example `const tab = await iab.tabs.new()`. If a later turn reports that a tab is missing, stale, closed, or not part of the current browser session, discard that tab binding and obtain or create a fresh tab from the existing browser binding. An empty `browser.tabs.list()` or `browser.user.openTabs()` result is normal after tab cleanup and does not invalidate the browser binding. Never call `agent.browsers.get*` to recover a tab; only an explicit browser-disconnected error invalidates the binding. + +## Browser selection + +Keep browser actions in the browser hosting the current chat unless the user explicitly names another browser. + +The scenarios below are for the initial browser selection only. Before calling any `agent.browsers.get*` method, reuse an existing `browser`, `iab`, `chrome`, or `edge` binding that already serves the task. A new user turn does not invalidate a browser binding or require another selection or documentation call. + +Select the initial browser with exactly one of these scenarios, in the order +shown. An explicit request for the in-app browser, Chrome, or Edge always wins +over URL selection. Never call `getForUrl()` when the user names a browser. +An explicit browser request is a hard constraint: use only that browser and +never fall back to another browser surface. If its exact selector is +unavailable, report that browser as unavailable instead of calling +`getDefault()`, `getForUrl()`, or `get("extension")`. + +App-provided in-app-browser context is ambient UI state, not a user instruction to select or switch browsers. Only the text of the user's request can explicitly choose a browser. + +Do not inspect browser cookies, local storage, profiles, passwords, or session stores. Browser discovery must remain read-only. + +When authentication blocks requested browser navigation, do not replace it with web search, a search engine, another site, or another source merely to bypass sign-in. + +### The user explicitly requests a browser + +A plugin mention in the user's request explicitly names its browser. +`[@Browser](plugin://browser@openai-bundled)` names the in-app browser. +Browser plugin mentions whose URL contains `browserFamily=chrome` or +`browserFamily=edge` name Chrome or Edge respectively. +`[@Chrome](plugin://chrome@openai-bundled)`, +`[@chrome-internal](plugin://chrome-internal@openai-bundled)`, and +`[@chrome-dev](plugin://chrome-dev@openai-bundled)` name Chrome. Follow the +corresponding explicit-browser scenario below. + +The in-app browser is available only when the Browser skill is listed for the session. If the user explicitly requests the in-app browser and that skill is available, use a distinct persistent binding and immediately read its complete documentation: + +```js +const iab = await agent.browsers.get("iab"); +nodeRepl.write(await iab.documentation()); +``` + +If the user explicitly requests the in-app browser but the Browser skill is not available, report that the in-app browser is unavailable instead of substituting another browser. + +Chrome or Edge is available only when a Browser or Chrome skill is listed for +the session and `agent.browsers.get("chrome")` or +`agent.browsers.get("edge")` succeeds. The browser family is a stable selector; +do not list browsers first or pass an opaque browser ID for an explicit family. + +For Chrome, use a separate persistent binding and immediately read its complete +documentation: + +```js +const chrome = await agent.browsers.get("chrome"); +nodeRepl.write(await chrome.documentation()); +``` + +For Edge, use its own persistent binding and immediately read its complete +documentation: + +```js +const edge = await agent.browsers.get("edge"); +nodeRepl.write(await edge.documentation()); +``` + +If the user explicitly requests Chrome or Edge but that family is unavailable, +tell them that browser needs the ChatGPT browser extension and direct them to +**Settings → Computer use** to install it. Do not substitute another browser. + +An explicit browser choice remains in force for the task. If authentication blocks the task in an explicitly selected browser, your next response must explicitly ask the user to sign in in that browser and tell you when it is ready, unless that browser's documentation provides a supported authentication flow to try first. Merely reporting that sign-in is required is not sufficient. Do not switch to another browser unless the user asks or approves the switch. + +### The user explicitly requests an external browser without naming a family + +When the user says to use their external browser, browser extension, or a +similar external-browser surface without naming Chrome or Edge, select the +first connected extension instance directly. Do not call +`agent.browsers.list()` first: + +```js +const browser = await agent.browsers.get("extension"); +nodeRepl.write(await browser.documentation()); + +The in-app browser setup requires reading the browser-client module and connecting. This is a heavier path. But before that, let me reconsider: maybe I can get Matter.js another way — e.g., from the npm cache on disk, or from Python's pip? Let me search more broadly for "matter" related files, and also check if there's an npm cache. + +Actually — better idea: the first Chrome instance DID load the CDN. That means network to cdnjs worked at least once from Chrome. Maybe DNS/proxy is flaky but retrying eventually works. Let me try launching Chrome in a loop with longer waits and checking until one loads Matter. Actually I did 3 attempts all failed. Hmm. + +Alternatively, maybe the sandbox network allows only specific hosts or only at certain times. The user's real environment presumably has network (they'll open index.html in their browser). For MY testing purposes, the critical thing is to verify the game logic works. + +Approach: **Inject a local Matter.js into the test page**. I need the source. Since I can't download it, options: +1. Write a minimal physics stub? No — that wouldn't test the real physics. +2. Find matter-js source in some package cache. Let me search npm cache: C:\Users\guzhu\AppData\Local\npm-cache. Also check for any python packages. And maybe `C:\Users\guzhu\AppData\Local\ms-playwright` (playwright browser downloads) — no matter-js there. + +3. Use the in-app browser (plugin) — it might have network via the ChatGPT runtime. The browser-client connects to a browser with its own profile; whether it has network egress is unknown but plausible (the plugin is part of the chat runtime which had network earlier for the first screenshot... hmm, that was the same sandbox). + +Wait, actually — let me reconsider. The first screenshot rendered the game, so Matter loaded. Let me check whether that first chrome profile/cache still exists and extract matter.min.js from Chrome's HTTP disk cache. The temp profiles were created in $env:TEMP. Let me list them. + +Chrome cache extraction: files under \Default\Cache\Cache_Data\f_* are the cached resources. matter.min.js would be one of them. I can grep the f_ files for "Matter" signature. The cache data files are raw (not encrypted for http). Each f_ file may contain multiple entries but usually one resource. I can scan for a file containing "Matter.Engine" text. Let me try that. + +Actually — even better: the GPU-less headless chrome writes cache but for a file:// page loading https CDN, the response is stored in the HTTP cache.

Hmm, but the game rendered! Maybe the game rendered via... wait, did it? Let me re-examine the first screenshot more carefully. Looking at the screenshot description again: it showed the game canvas with HUD, red dashed line, preview ball with prediction line, and floor walls. For the game to render, `Matter` must be defined (guard). + +Unless... the guard is `typeof Matter === 'undefined'`. If the CDN script failed, Matter is undefined → body replaced.

OR the body replacement happened but the screenshot... no, the game was clearly visible. + +Hmm wait — maybe I should double check the screenshot: the image showed a game-looking canvas. Yes it clearly did. So Matter loaded during that run. But it's not in the cache files. Odd. Maybe the cache wasn't flushed to disk (chrome was killed via the tool ending). + +OK — different approach for getting Matter.js: **retry fetching from the page itself or from node repeatedly**. Network might be intermittently available. The first attempt succeeded at ~19:37, later attempts failed. Maybe there are windows. Let me run a retry loop in node_repl: 15 attempts × 4s = 60s, fetching matter.min.js. If any succeeds, I have the source and can inject it. + +Also try alternate CDNs/mirrors: +- https://cdn.jsdelivr.net/npm/matter-js@0.19.0/build/matter.min.js +- https://unpkg.com/matter-js@0.19.0/build/matter.min.js +- https://cdnjs.cloudflare.com/...

OK, so I can't fetch Matter.js from the internet. + +Alternative: I recall the first screenshot succeeded. Maybe the network allows only HTTPS to certain domains occasionally. This is a sandbox limitation, not a problem with the deliverable itself. + +Let me think about what I CAN verify without Matter: +1. The game's fallback path works correctly (Matter missing → clear error message) — already verified. +2. JS syntax — verified via node --check. +3. HTML structure, SVG strings, weights, etc. — verified. +4. **The game logic that doesn't depend on Matter**: I could unit-test the pure logic functions (pickLevel weights, isMergeable, comboBonus, predictLandingY, doMerge flow) by extracting them into a test harness with a Matter STUB. That's actually quite valuable — I can verify the merge logic, weights, scoring, and game-over logic with a fake Matter.js that mimics the API surface I use (Bodies.circle, Body.setStatic, Composite.add/remove, Events.on, Engine.create/update, Sleeping.set). + +Writing a Matter stub that implements enough physics to simulate: circles falling, colliding... that's essentially writing a physics engine. Too much. + +BUT — I can do a "logic harness" test differently: stub Matter's API minimally (Engine.create returns object with world; Bodies.circle returns a body with position/mass/isStatic/isSleeping; Composite.add/remove manipulate a body list; Events.on stores handlers; Body.setStatic sets isStatic; Engine.update triggers collisionStart handler with pairs I control). Then I extract the game's core functions (isMergeable, doMerge, comboBonus, pickLevel, wakeNearbyBalls, checkGameOver, scoring) from index.html and run them against crafted scenarios: +- Two same-level balls near each other → doMerge creates next level, score += newLevel*10, maxUnlocked increases. +- Different levels → no merge. +- Distance > sum+10 → no merge. +- Removed/static → no merge. +- Combo: two merges within 900ms → combo bonus. +- pickLevel with only level 1 → always 1; after unlock, weights match table (statistical check). +- checkGameOver: ball top above LINE_Y for >700ms → game over. +- 9+9 → no level 10, score 90+bonus. +- Celebration triggered on level 9 creation. + +This gives solid confidence in the core game logic without Matter or a browser. Let me build this harness in node_repl: +1. Read index.html, extract the JS. +2. Strip browser-specific parts? The JS is one big IIFE using document/canvas/requestAnimationFrame. I'll create a fake `document` and `canvas` context that absorb calls (2d context with no-op methods), fake performance, requestAnimationFrame, Image, PointerEvent... Then `new Function('window','document','performance','Image','requestAnimationFrame', js)` — the code references global Matter too. I'll inject a Matter stub before running. + +The stub's `Engine.update` should trigger the stored collisionStart handlers with provided pairs — but the game's processMerges is called from update(); merges happen via doMerge called in processMerges. The collision detection in real life comes from Matter; in my harness, I'll manually call the engine's collisionStart handler with body pairs, then call the game's `update(16.67)` to process merges. + +But the game functions are inside the IIFE — not accessible from outside. However, I CAN access them if I modify the harness: wrap the extracted JS and append `window.__test = { isMergeable, doMerge, ... }`? The functions are declared inside the IIFE closure; to expose them I'd need to edit the JS. Instead, I can patch the JS string: insert an exposure snippet before the closing `})();` — e.g., replace the final ` init();\n})();` with ` init();\n window.__T = { LEVELS, WEIGHTS, isMergeable, doMerge, comboBonus, pickLevel, wakeNearbyBalls, checkGameOver, triggerGameOver, createBall, balls, engine, maxUnlocked, score };` then `})();`. This is a TEST-ONLY transformation on the extracted string — doesn't modify the deliverable. + +Then in the harness: +- Stub Matter: Engine.create → {world: {bodies: []}}, Events.on stores handler by name, Bodies.circle returns {gameData:null, position:{x,y}, mass: computed from density*area, isStatic:false, isSleeping:false, sleepThreshold:60}, Body.setStatic sets isStatic, Composite.add/remove push/splice bodies, Sleeping.set sets isSleeping, Engine.update → advance time + fire stored 'collisionStart'? For my tests I'll fire collisionStart manually via the stored handler. + +The game's `createBall` uses Bodies.circle + Composite.add + balls.push. The game's `dropBall` uses LEVELS, clamp, heldX. I can call `__T.createBall(x, y, level)` directly, then simulate collisions by calling the stored collisionStart handler with two bodies, then call `__T.update(dt)`... wait `update` is also inside IIFE — I should expose `update` and `render` too. render needs canvas — stub handles it. + +Actually simpler: expose `update` as `__T.update` so I can drive merges via update(). And expose `processMerges` indirectly through update. Good. + +Let me also expose `state` and `confetti`/`particles` to check effects. + +Test plan in harness: +1. Load JS with stubs. `init()` will run: preloadBadges (creates Image — stub with onload never firing → BADGE_CACHE stays empty, fallback used — fine), createWorld (Matter stub), pickLevel (initial pool level 1 → currentLevel=1, nextLevel=1), requestAnimationFrame stub (store callback, don't run). +2. Test pickLevel: with maxUnlocked=1, 1000 draws → all 1. Then set maxUnlocked via a merge. +3. createBall(180, 500, 1) ×2 at same spot → fire collisionStart(handler)(pairs) → update(70) → merge should create level 2 ball at weighted center, score=20, maxUnlocked=2. +4. Verify balls array: two level-1 removed, one level-2 present. +5. Combo test: two merges quickly → combo bonus. Create two level-2 balls, merge → +30 +5? newLevel=3: 30 + (combo-1)*5. First merge (lvl1→2) combo=1. If within 900ms second merge (lvl2→3): combo=2 → +30+5. +6. 9+9 test: directly set up two level-9 balls (createBall with level 9), merge → both removed, score +90(+bonus), no level 10 ball, celebration confetti length 90. +7. Game over: place a level-1 ball above LINE_Y, call update with dt=100 ×8 → triggerGameOver → state='over', overlay hidden removed (stub document.getElementById returns fake elements). +8. isMergeable negative cases: different levels, removed, static, far apart. +9. Weights statistical check for maxUnlocked=9: distribution roughly matches. + +This is a robust logic test. Let me build it. + +I need a fake document with getElementById returning stub elements with classList add/remove, textContent, addEventListener. And canvas with getContext returning Proxy that absorbs any method. requestAnimationFrame: store callback; do not run (to avoid the loop). performance.now: real. Image: class with src setter. + +Matter stub details: +- Engine.create(opts) → { world: { bodies: [], gravity: opts.gravity }, events: {} } +- Events.on(engine, name, cb) → engine.events[name] = cb +- Bodies.circle(x, y, r, opts) → body = { position: {x,y}, circleRadius: r, mass: Math.PI*r*r*(opts.density||0.001), isStatic: !!opts.isStatic, isSleeping: false, sleepThreshold: opts.sleepThreshold||60, label: '', gameData: null } +- Body.setStatic(b, v) → b.isStatic = v +- Composite.add(world, item) → push (array or single) +- Composite.remove(world, body) → splice +- Sleeping.set(b, v) → b.isSleeping = v +- Engine.update(engine, dt) → no-op (I'll drive collisions manually) + +The game's createWorld adds walls (static bodies). isMergeable requires both non-wall (gameData) — walls have no gameData → fine. + +Now, one catch: the game's `update(dt)` also filters balls and updates effects and calls processMerges and checkGameOver. Good. + +Another catch: `init()` calls `requestAnimationFrame(loop)` — my stub stores it; loop never runs, so Engine.update never called in loop — I call update() manually. Good. + +Also `preloadBadges` — Image stub: I'll set src but no onload → BADGE_CACHE empty → drawBadge fallback. Fine (render not tested visually here). + +The exposure patch: replace ` init();\n})();` with exposure + same. Let me write the harness. + +Also expose `startCelebration` and `spawnMergeEffects`/`spawnFloatingText` via __T for effect checks. + +Let me now write this harness in node_repl. It's long; I'll build the Matter stub and eval the patched JS in a Function with a sandbox object. Use `new Function('window','document','performance','requestAnimationFrame','Image','Matter','navigator', jsWithExposure)`. The IIFE uses `document`, `performance`, `Image`, `requestAnimationFrame`, `Matter` — all provided. Also `Math`, `setTimeout` etc. are globals (fine in node). + +Note the code references `canvas.setPointerCapture` etc. — only in event handlers, not executed at load. Good. + +Let me write it. +codex +网络彻底不可用。改用“逻辑测试台”方案：用 Matter.js API 桩 + 浏览器桩加载游戏脚本，直接验证核心玩法逻辑（合成、计分、连击、解锁、9+9、游戏结束、权重分布）。先构造沙箱： +mcp: node_repl/js started +mcp: node_repl/js (completed) +`new Function` is blocked in node_repl ("Code generation from strings disallowed"). This is a CSP-like restriction in the REPL context. I need another way to evaluate the JS. + +Options: +1. Write the harness + game JS to a temp file and run it with `node` via shell_command (node --check worked via shell; running a node script file should work too — the restriction is only inside node_repl). +2. Use `node:vm` module — might also be restricted. Let me test vm.runInNewContext quickly. If blocked, go with option 1. + +Option 1 is reliable: write `_harness.mjs` (or .js) to D:\integrate_sjtu\, run `node _harness.js` via shell. The harness builds the sandbox, loads the patched game JS via `new Function` (allowed in a plain node script, no CSP), runs the tests, prints results. + +Let me write the harness file via node_repl (fs.writeFileSync with the harness content as a template literal — it contains backticks? The harness JS I wrote uses template literals with ${}? Let me avoid template literals inside the harness to make embedding easy... Actually I'm writing it via node_repl where I control the string; the harness content itself can use template literals as long as I escape them in MY outer template literal. Simpler: build the harness content with String.raw? Hmm. + +Cleanest: write the harness to disk using apply_patch? apply_patch has CRLF issues. Write via PowerShell small here-strings? The harness is ~150 lines (~5KB) — too big for one PowerShell chunk reliably. + +Alternative: use node_repl to write the harness file, but build it from an array of lines joined by \n — avoids backtick/quote escaping issues entirely since each line is a normal string in MY code. But writing ~150 line strings is verbose but safe. + +Actually — simpler: in node_repl, I can write the harness content as a JS template literal and escape the few backticks in it. My harness code contains template literals like `\`(() => ({...}))()\``? No — that was the CDP code. The LOGIC HARNESS doesn't need template literals except maybe for the exposure snippet. Let me write the harness WITHOUT any template literals/backticks (use string concat), then embed in an outer template literal — no escaping needed. + +Let me design the harness file (_harness.js): + +```js +const fs = require('node:fs'); +const path = require('node:path'); +const html = fs.readFileSync(path.join(__dirname, 'index.html'), 'utf8'); +const start = html.indexOf('(function () {'); +const end = html.lastIndexOf(''); +let js = html.slice(start, end); +const exposure = '\n window.__T = {...};\n init();\n})();'; +js = js.replace(' init();\n})();', exposure); +... stubs ... +const fn = new Function(...); fn(...); +... tests ... +console.log(JSON.stringify(results, null, 2)); +``` + +Wait — `require` in a .js run by node: fine (CJS). I'll write it as CommonJS .js. But the game JS uses 'use strict' IIFE — fine. + +One concern: `new Function` in a normal node process — allowed. Good. + +The tests to run: +T1 initial: currentLevel===1, nextLevel===1 (pool only level1), score===0, maxUnlocked===1. +T2 pickLevel distribution for maxUnlocked=1: 2000 draws all ===1. +T3 merge level1+level1: create two balls at (180,500) and (182,500) → fire collisionStart → update(70) → expect: balls has one level2 ball, score===20, maxUnlocked===2, particles.length>0, rings.length>0, floaters.length>0. +T4 combo: lastMergeTime recent → create two level2 → merge → score += 30+5=35 (total 55), combo===2. +T5 isMergeable negatives: (a) different levels → false; (b) removed → false; (c) static → false; (d) far apart → false; (e) wall vs ball → false. +T6 9+9: create two level9 at same spot, fire collision, update → expect both removed, no level10, score += 90 + combo bonus, confetti NOT triggered by 9+9 (only on creation of 9). Also confetti length check for celebration: create level 8 pair → merge → creates level9 → confetti length 90. +T7 game over: create level1 ball at (180, 60) (top = 60-25=35 < 96), call update(100) 8 times → state==='over'. +T8 weights distribution for maxUnlocked=9: set via merging? Easier: directly set T.maxUnlocked=9 then draw 5000 samples, check each bin within ~±30% of expected proportion. +T9 wakeNearbyBalls: create sleeping ball within radius → sleepThreshold reset to 60 and isSleeping false. + +Fire collision handler: `T.engine.events.collisionStart({ pairs: [{ bodyA, bodyB }] })`. + +Note: after createBall, bodies have gameData set. I keep references to the created bodies: T.createBall returns gd → gd.body. + +Note about doMerge: uses Body.setStatic (stub), Composite.remove (stub), spawnMergeEffects (pushes to particles/rings), comboBonus, addScore, createBall, startCelebration (pushes 90 confetti), wakeNearbyBalls. All should work with stubs. + +checkGameOver uses gd.body.position.y - radius < LINE_Y and gd.timeAboveLine accumulation. update(dt) calls checkGameOver only when state==='playing'. + +One subtlety: update() filters `balls = balls.filter(g => !g.isRemoved)` — fine. + +Another subtlety: my update() call processes pendingMerges with MERGE_DELAY=60ms; performance.now() is real time — first collision fires at t0, update immediately processes → now - time < 60 → stays pending; next update(70) → processed. Actually update(dt) calls processMerges() each time; first call may leave it pending; second call processes. I'll call update(70) twice to be safe. + +Also careful: T.dropBall uses heldX and cooldown — not needed for these tests (I create balls directly). + +Let me also verify the exposure replace worked (js includes '__T'). + +Now, writing the file via node_repl: I'll build the harness source as an array of lines? That's painful. Instead use a template literal with NO backticks inside and no ${...} that I don't intend. My harness code has template literals? I'll write it avoiding them. The only backtick risk is none. ${} — avoid by using string concat in harness. + +Actually the exposure string uses no template. Fine. + +Let me write the harness content. I'll write it in one node_repl call via fs.writeFileSync with a big template literal. Size ~6KB — node_repl handled 8KB+ fine. + +Then run `node D:\integrate_sjtu\_harness.js` via shell. + +Let me write the harness now. I must be careful that within the outer template literal in node_repl code, any `\`` or `${` in the harness would need escaping — I'll avoid both. + +Harness code (CJS): + +```js +'use strict'; +const fs = require('node:fs'); +const path = require('node:path'); +const ROOT = __dirname; +const html = fs.readFileSync(path.join(ROOT, 'index.html'), 'utf8'); +const start = html.indexOf('(function () {'); +const end = html.lastIndexOf(''); +let js = html.slice(start, end); +const exposure = '\n window.__T = { LEVELS: LEVELS, WEIGHTS: WEIGHTS, isMergeable: isMergeable, doMerge: doMerge, comboBonus: comboBonus, pickLevel: pickLevel, wakeNearbyBalls: wakeNearbyBalls, checkGameOver: checkGameOver, triggerGameOver: triggerGameOver, createBall: createBall, update: update, render: render, balls: balls, engine: engine, maxUnlocked: maxUnlocked, score: score, combo: combo, lastMergeTime: lastMergeTime, pendingMerges: pendingMerges, particles: particles, rings: rings, floaters: floaters, confetti: confetti, state: state, cooldown: cooldown, currentLevel: currentLevel, nextLevel: nextLevel, startCelebration: startCelebration };\n init();\n})();'; +if (!js.includes(' init();\n})();')) throw new Error('exposure anchor not found'); +js = js.replace(' init();\n})();', exposure); +``` + +Hmm — variable names inside exposure: `balls: balls` — but at that point in the IIFE, these are `let` bindings; creating an object referencing them works. + +Matter stub — same as before. + +Document stub — same. + +Then the tests. Let me write carefully. + +For the "collisionStart fire" helper: +```js +function collide(a, b) { + T.engine.events.collisionStart({ pairs: [{ bodyA: a.body, bodyB: b.body }] }); +} +``` +Wait — handleCollisions expects event.pairs with bodyA/bodyB. The game stores pendingMerges with a,b = bodies. doMerge uses bodyA.gameData. Good. But `T.engine` — engine is exposed. engine.events.collisionStart is the registered handler. Good. + +Then `T.update(70)` twice to process the 60ms delay. + +For checkGameOver, T.update(100) 8 times accumulates 800ms > 700ms → triggerGameOver → state 'over'. + +For the T5 negative tests, I need fresh non-removed balls: create level1 ball A at (100,100) and level2 ball B at (100,100) — different levels → isMergeable false. For removed: create two level1, mark gd.isRemoved=true on one. For static: Body.setStatic... I have Matter stub's Body — but the harness can directly set a.body.isStatic = true. For distance: create at (100,100) and (300,300) → distance 283 > 25+25+10=60 → false. For wall: engine world static wall body has no gameData → isMergeable false (a.body from createBall has gameData, wall doesn't). Good — I can grab a wall from T.engine.world.bodies (they were added in createWorld). + +For T6 (9+9): create two level9 balls at same pos. Merge → newLevel=10 → else branch: gained=90+comboBonus, no new ball. Confetti: NOT triggered (startCelebration only in the newLevel<=9 branch when newLevel===9). But wait — after T4/T3, maxUnlocked might be 3; fine. + +For celebration test: create two level8 at same pos, merge → creates level9 → confetti.length===90, maxUnlocked===9. + +Order the tests to keep state simple; each test prints result. Let me accumulate results into an array and print JSON. + +T8 weights: set T.maxUnlocked = 9 (it's a let binding exposed by reference — the exposure object captures the BINDING? NO — `maxUnlocked: maxUnlocked` captures the VALUE at exposure time, not a live reference!). Since exposure happens inside the IIFE at the end, it captures current values (all zero/initial). Assignments inside the game (e.g., `maxUnlocked = newLevel`) update the closure variable, but my exposure object's `maxUnlocked` property still holds the initial value! + +So I can't read/write live state through the exposure object for `let` variables. Damn. The functions ARE live references (function declarations) — calling them works and mutations happen inside the closure. But READING maxUnlocked/score/combo after merges won't reflect changes. + +Solution: expose GETTERS via object literal getters? Can't — getters need to reference the closure var at call time: `get maxUnlocked() { return maxUnlocked; }` — that works! Let me use accessor properties in the exposure object: + +```js +window.__T = { + get score() { return score; }, + get combo() { return combo; }, + get maxUnlocked() { return maxUnlocked; }, + get balls() { return balls; }, + get state() { return state; }, + get confetti() { return confetti; }, + get particles() { return particles; }, + get rings() { return rings; }, + get floaters() { return floaters; }, + get currentLevel() { return currentLevel; }, + get nextLevel() { return nextLevel; }, + get lastMergeTime() { return lastMergeTime; }, + get cooldown() { return cooldown; }, + set maxUnlocked(v) { maxUnlocked = v; }, + ... +} +``` + +But the game code itself has `let maxUnlocked` — setters inside the exposure can write it. + +Also `pendingMerges` getter returns the array reference — fine. + +Let me rewrite exposure with getters/setters. This avoids the stale-value problem entirely. + +Also for `balls`, I need to inspect bodies: ball gd objects have .body.position, .level, .isRemoved — getter returns live array. + +Now the harness: write with fs via node_repl template literal (no backticks/${). Let me write it. + +Also: the `render` exposure isn't needed for logic tests (render needs canvas — my stub ctx handles it, but I won't call render). + +Let me write the file. +codex +`new Function` 在 REPL 内被禁止，改用独立 `node` 脚本运行测试台。用 getter/setter 暴露闭包内实时状态，写 `_harness.js`： +mcp: node_repl/js started +mcp: node_repl/js (completed) +Harness written.

Let me think about the flow: +1. `collide(a1, a2)` → calls `T.engine.events.collisionStart({pairs: [...]})` → handleCollisions → isMergeable(a1.body, a2.body) → checks: both have gameData, same level (1), not removed, not static, distance ≤ limit. + +Wait — a1 = T.createBall(180, 500, 1). createBall returns gd. In my stub, Bodies.circle returns a body WITHOUT gameData — but createBall sets `body.gameData = gd`. Good. a1.body.gameData = gd. + +distance between (180,500) and (184,500) = 4 ≤ 25+25+10=60 → mergeable → pendingMerges.push. + +2. waitUpdate(70, 2) → T.update(70) twice. update calls processMerges → checks `now - q.time >= MERGE_DELAY (60)`. + +AH — here's the issue! `performance.now()` in the harness: collide() pushes pendingMerges with `time: performance.now()`. Then immediately `T.update(70)` → `now - q.time` ≈ 0.2ms < 60 → pending. Second T.update(70) → now - time ≈ 0.4ms < 60 → still pending!! Because my update() doesn't actually advance time — it just processes merges with real clock time. The real game runs at 60fps where each update is 16.6ms real time, so 60ms delay = ~4 frames. In my harness, calling update back-to-back happens within microseconds of real time. + +Fix: wait 70ms real time between updates. Let me add `await sleep(70)` — but the harness is synchronous (CJS, no top-level await). I can use a synchronous busy-wait: `const t0 = Date.now(); while (Date.now() - t0 < 70) {}` in waitUpdate. Simple. + +Also T7 'lvl9=2' — interesting: it says countLevel(9)===2 at that point?? Wait, T7 failed with "lvl9=2" — that's odd. Before T7, T6 created two level-9 balls (e1, e2) which failed to merge (still present!). Then T7 creates two level-8 balls → if they merged... no, merges aren't working due to the timing issue. So lvl9=2 counts e1+e2 from T6. Right. + +And "T6 no level10 ball" passed trivially (no merge → no level 10). + +So the ONLY issue is the timing in the harness. Let me fix waitUpdate to busy-wait at least 70ms before processing. I'll change waitUpdate to: busy wait 70ms, then call update once or twice. Actually processMerges is called each update; one update after 70ms real delay suffices. Let me modify: + +```js +function waitUpdate(ms, times) { + times = times || 1; + const t0 = Date.now(); + while (Date.now() - t0 < Math.max(ms, 80)) {} + for (let i = 0; i < times; i++) T.update(ms); +} +``` + +Wait, but T9 (game over) calls waitUpdate(100, 8) — with busy wait 100ms then 8 updates — timeAboveLine accumulates 800ms across 8 updates → game over. Fine. + +Hmm, but there's a subtlety: pendingMerges with performance.now()-based delay — after busy-wait 80ms, now - time > 60 → processed on first update. Good. + +Also T4's "score=55" and combo logic should then work. + +Let me also double check T3's weighted center: two equal-mass balls at (180,500) and (184,500) → cx = (180*m + 184*m)/(2m) = 182. My check expects 182. Good. + +One more: in T7, after fixing, e1/e2 (level9) will merge (T6) → removed; then f1/f2 (level8) merge → level9 created → confetti 90, maxUnlocked 9. lvl9 count = 1. Good. + +Also note T6 runs AFTER T4 where combo might be 2 — comboBonus for 9+9: gained = 90 + comboBonus. The check computes expected delta using T.combo at check time. Since T.combo getter returns live value, and comboBonus updates combo... The check `T.score === before + 90 + (T.combo > 1 ? (T.combo-1)*5 : 0)` — I read T.combo AFTER the merge; comboBonus already incremented it. That matches the delta computed. OK. + +Let me patch waitUpdate in _harness.js. +codex +发现测试台问题：合成延迟按真实时钟判断（60ms），而测试里连续 update 间隔只有微秒级，合成一直处于 pending。修正为真实延时后再 update： +mcp: node_repl/js started +mcp: node_repl/js (completed) +exec +"C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe" -Command "node D:\\integrate_sjtu\\_harness.js" in D:\integrate_sjtu + succeeded in 1235ms: +{ + "results": [ + { + "name": "T1 initial currentLevel=1", + "pass": true, + "detail": "current=1" + }, + { + "name": "T1 initial nextLevel=1", + "pass": true, + "detail": "next=1" + }, + { + "name": "T1 initial score=0", + "pass": true, + "detail": "score=0" + }, + { + "name": "T1 initial maxUnlocked=1", + "pass": true, + "detail": "unlocked=1" + }, + { + "name": "T1 balls empty", + "pass": true, + "detail": "n=0" + }, + { + "name": "T2 pool[1] always level1", + "pass": true, + "detail": "" + }, + { + "name": "T3 merged to level2", + "pass": true, + "detail": "lvl2=1" + }, + { + "name": "T3 lvl1 removed", + "pass": true, + "detail": "lvl1=0" + }, + { + "name": "T3 score=20", + "pass": true, + "detail": "score=20" + }, + { + "name": "T3 maxUnlocked=2", + "pass": true, + "detail": "unlocked=2" + }, + { + "name": "T3 particles spawned", + "pass": true, + "detail": "n=14" + }, + { + "name": "T3 rings spawned", + "pass": true, + "detail": "n=1" + }, + { + "name": "T3 floaters spawned", + "pass": true, + "detail": "n=1" + }, + { + "name": "T3 new ball has level 2 at weighted center", + "pass": true, + "detail": "x=182" + }, + { + "name": "T4 combo=2", + "pass": true, + "detail": "combo=2" + }, + { + "name": "T4 score=55 (20+35)", + "pass": true, + "detail": "score=55" + }, + { + "name": "T4 merged to level3", + "pass": true, + "detail": "lvl3=1" + }, + { + "name": "T5 diff level no merge", + "pass": true, + "detail": "" + }, + { + "name": "T5 removed no merge", + "pass": true, + "detail": "" + }, + { + "name": "T5 static no merge", + "pass": true, + "detail": "" + }, + { + "name": "T5 far apart no merge", + "pass": true, + "detail": "" + }, + { + "name": "T5 wall no merge", + "pass": true, + "detail": "" + }, + { + "name": "T6 no level10 ball", + "pass": true, + "detail": "maxlvl=3" + }, + { + "name": "T6 9+9 score += 90+bonus", + "pass": true, + "detail": "delta=100" + }, + { + "name": "T7 level9 created", + "pass": true, + "detail": "lvl9=1" + }, + { + "name": "T7 maxUnlocked=9", + "pass": true, + "detail": "unlocked=9" + }, + { + "name": "T7 confetti=90", + "pass": true, + "detail": "n=90" + }, + { + "name": "T8 weights distribution ok", + "pass": true, + "detail": "counts=983,765,707,582,486,452,377,335,313" + }, + { + "name": "T9 game over state", + "pass": true, + "detail": "state=over" + }, + { + "name": "T10 sleeping ball woken", + "pass": true, + "detail": "sleep=false thr=60" + }, + { + "name": "T10 far ball untouched", + "pass": true, + "detail": "sleep=true" + }, + { + "name": "T11 cooldown=480 after drop", + "pass": true, + "detail": "cooldown=480" + }, + { + "name": "T11 currentLevel advanced", + "pass": true, + "detail": "cur=1 nextBefore=1" + }, + { + "name": "T11 dropped ball exists", + "pass": true, + "detail": "n=12" + } + ], + "summary": { + "pass": 34, + "fail": 0, + "total": 34 + } +} + +All 34 tests pass: +- T1: initial state correct (pool only level 1) +- T2: pickLevel always 1 when only level 1 unlocked +- T3: merge 1+1 → level 2, score 20, unlock 2, particles/rings/floaters, weighted center (x=182) +- T4: combo: second merge within 900ms → combo=2, score 20+35=55 +- T5: all isMergeable negative cases +- T6: 9+9 → removed, no level 10, +90+bonus (delta=100 — that's 90 + combo bonus where combo was 3: (3-1)*5=10 → 100.

Now let me also verify the SVG data URIs actually decode and the badge rendering pipeline works (Image loading). I can test the SVG→data URI decode in node: parse each SVG string from the file, encodeURIComponent, decode, verify well-formed XML (with a quick XML parser? Node doesn't have DOM XML parser built-in... I can use a simple regex/well-formedness check, or check that encodeURIComponent round-trips and the strings match the source SVG files exactly). + +Let me verify: extract SVG strings from index.html and compare with the 9 SVG files in assets/ — exact equality after unescaping. That confirms the inlining was faithful. Since SVG strings are inside template literals, extraction: find lines between `const SVG_STRINGS = [` and `];` and strip leading/trailing backticks and commas. Compare with file contents (normalizing line endings). + +Also verify the data URI generation works: `'data:image/svg+xml;charset=utf-8,' + encodeURIComponent(svg)` — in node, decode and parse with a proper check. Let me do a simple well-formedness check via regex for matching tags (enough). + +Also — I still haven't done a REAL browser render test with actual Matter physics. The first screenshot verified initial rendering with real Matter (it loaded then). The logic tests verify merge/score/game-over logic. The remaining gap: real physics behavior (Matter.js actual collisions triggering collisionStart) — that's Matter's job and the integration is standard. I'm fairly confident. But let me try ONE more time to get a real browser render — maybe I can find network again. Actually, let me check if the in-app browser (browser plugin) has network. If it does, I can do a full E2E test there (real Matter + real rendering + real input). Let me try the browser-client setup quickly. + +Actually — wait. Let me reconsider the effort/benefit. The key risks: +1. JS syntax — verified (node --check). +2. Core logic — verified via harness (34/34). +3. Initial render + Matter CDN load — verified via the first screenshot (game rendered with real Matter). +4. SVG inlining faithfulness — will verify next. +5. Real physics interaction (collisionStart from Matter) — this is standard Matter usage; low risk. But a full E2E would be ideal. + +Let me try the in-app browser once — if the setup fails or network unavailable, I'll accept the current verification level. The skill says use browser-client.mjs with setupBrowserRuntime(). Let me try. +codex +逻辑测试台 34/34 全部通过（合成、计分、连击、解锁、9+9、撒花、越线判定、权重、唤醒、冷却）。现在验证 SVG 内联与原文件一致性，并尝试用 in-app 浏览器做真实渲染测试： +mcp: node_repl/js started +mcp: node_repl/js (completed) +All 9 SVG strings inline exactly match the source files, and the data URI generation decodes correctly. + +Now let me try the in-app browser for a real E2E test. Set up the browser runtime per the skill. The plugin root: C:\Users\guzhu\.codex\plugins\cache\openai-bundled\browser\26.820.60940. The script: scripts/browser-client.mjs.

Let me try `agent.browsers.get("chrome")` or `agent.browsers.get("extension")` — maybe a Chrome extension connection is available. The skill said for Chrome: `agent.browsers.get("chrome")`. Let me try chrome and edge, and also list browsers. +codex +iab 不可用，尝试 Chrome/Edge/扩展连接： +mcp: node_repl/js started +mcp: node_repl/js (completed) +No browsers available via the plugin (no Chrome extension installed, no in-app browser in this environment). So the in-app browser path is out. + +Given that: +- The first screenshot proved the game renders with real Matter (when CDN was reachable). +- Logic tests pass 34/34. +- SVG inlining verified exact. +- JS syntax verified. + +The remaining untested piece is the real Matter collision→merge integration. Since I can't get network for the CDN, I could try ONE more creative approach: serve Matter from a LOCAL copy... which I don't have. OR: temporarily modify the page to use a `matter.js` fallback that I stub — but that changes the test, not real physics. + +Hmm wait — actually, let me reconsider. Maybe I can get network via the shell using a different mechanism (curl.exe?). The sandbox says "Network access is restricted." PowerShell Invoke-WebRequest failed. Chrome succeeded once. Let me try curl.exe quickly — maybe curl has different sandbox treatment. Also try `Test-NetConnection` or DNS. And try downloading via `certutil -urlcache`? Probably all blocked. One quick attempt with curl.exe won't hurt. + +Actually — hold on. Let me re-examine: maybe the first screenshot's success means Chrome network works when launched directly (not through my retry loop). The retry instances used the same launch approach and failed... Possibly the sandbox's network allowlist changes over time, or cdnjs was briefly allowed. + +Let me try curl.exe for a few CDN endpoints. If any works, I get Matter.js source, and then I can: +1. Write matter.min.js to a local file. +2. Create a temporary test copy of index.html that references the LOCAL matter (file://) — only for testing. +3. Run the full E2E via the CDP chrome instance (which I still have running on port 9334!). +4. Verify real physics merges, then delete the temp file.

Let me also do the PowerShell Set-Content -Encoding UTF8 roundtrip as the task instruction requires ("使用 PowerShell Set-Content -Encoding UTF8 写文件"). The file was written by node as UTF-8. To comply literally, I'll do a small PowerShell command reading the file and rewriting with Set-Content -Encoding UTF8. That command is small (no big inline content), so it shouldn't hit the hang issue. + +Wait — Set-Content -Encoding UTF8 in Windows PowerShell 5.1 adds a BOM. In PowerShell 7 it's no-BOM. Which PowerShell is the shell running? Let me check $PSVersionTable. BOM in HTML is fine (browsers handle it), and it matches "Set-Content -Encoding UTF8" instruction literally. But if the current shell is PowerShell 7, Set-Content -Encoding UTF8 produces no BOM (actually in PS7, -Encoding utf8 = no BOM; utf8BOM = BOM). Either way is fine. + +Hmm — one concern about the roundtrip: Get-Content -Raw then Set-Content might normalize line endings or add trailing newline. The file currently ends with `\n`? I wrote part9 ending with `\n` (the template literal ended with newline before the closing backtick). Let me check the file's tail. With -NoNewline, no extra newline added. Fine either way. + +Actually, do I really need the roundtrip? The task says "使用 PowerShell Set-Content -Encoding UTF8 写文件" — the intent is the file should be UTF-8. Node wrote it UTF-8. A roundtrip satisfies the letter of the instruction and is harmless. Let me do it. + +Also I should clean up test artifacts: _game_check.js, _harness.js, _t*.txt, _c1*.txt, _n1.txt, _shot/ dir, _part*.txt (none created), _test_patch.txt (not created), and the temp chrome profiles. Also kill the running chrome instances (port 9333, 9334). Let me clean up: +- Kill chrome processes I spawned (the retry ones).

Actually the harness already parsed the current file's JS (new Function compiled it and ran all tests) — that IS a full syntax+execution validation of the current file. Good enough, but let me do a quick fresh extraction + node --check anyway for completeness... Actually the harness passing means the current file's JS is valid and functional. Skip redundant check. + +Now cleanup: +1. Kill chrome instances (port 9333 and 9334 and any retry leftovers). I spawned them via node_repl child_process. Kill via __chrome (first, already killed), __cdp2.child (port 9334), and __chrome_retry leftovers. Also the first attempt on 9333 was killed already. Let me kill from node_repl (child.kill()) — cleaner than taskkill. Also there may be stray headless chrome processes from the failed `& $chrome` attempts... those exited with errors. Let me check running chrome processes related to headless and kill them. + +2. Delete temp files: _game_check.js, _harness.js, _t*.txt, _c1b.txt, _c1test.txt, _n1.txt, _shot dir, temp chrome profiles (chrome_headless_*, chrome_cdp_*, chrome_retry_*), matter_test.js in temp. + +Wait — should I delete _harness.js? It's a test artifact in the project dir. The user asked for index.html (and STATUS.md). Keep the workspace clean: delete test artifacts. But maybe keep the harness for future regression? The task says "其他文件已清空" for the project — the project should contain index.html + assets + 3 docs + the pre-existing prompt/ps1 files. I'll delete my test artifacts (_harness.js, _game_check.js, _t*.txt, _n1.txt, _c1b.txt, _shot) to keep it clean. Hmm — the harness could be useful, but it references the exposure patch trick; leaving it is clutter. Delete. + +Temp chrome profiles in %TEMP% — clean them too (they're in temp, will be cleaned by OS eventually, but tidy). + +3. Update STATUS.md: mark all tasks done, add completion record (测试结果 summary + 文件信息). + +4. Also update the STATUS "下一步" — completed. And per AGENTS.md 汇报 in Chinese. + +Let me also double-check the final index.html renders one more time? The roundtrip didn't change content materially (27890→27893 bytes — the 3-byte diff is probably BOM or `\r\n` normalization). Let me check if Set-Content changed line endings: PS7 Set-Content writes `\n`? Get-Content -Raw preserves the `\r\n`? Hmm, the original file was written by node with `\n` (LF). Get-Content -Raw in PS reads and keeps LF; Set-Content writes... in PS 7, Set-Content writes lines joined by `\n`? Actually Set-Content adds platform line ending? -NoNewline only controls the trailing newline. The content string itself has `\n` inside — Set-Content writes it as-is (the string contains `\n` from Get-Content -Raw). So line endings preserved (LF). The +3 bytes is likely a BOM (EF BB BF) added by Set-Content -Encoding UTF8 in PS 5.1 if that's the shell version. Either way, browsers handle BOM fine, and the harness re-parsed the file successfully. + +Wait, actually the harness's `js.includes(' init();\n})();')` anchor worked after roundtrip — so LF endings preserved (if CRLF had been introduced, the anchor ` init();\n})();` might still match since \r\n contains \n... The replace also worked. And tests passed. So file is fine. + +Let me quickly confirm BOM presence and line endings, then clean up and update STATUS.md. Actually not critical. Let me check quickly with node read of first bytes. +codex +验证全部通过。清理测试产物与临时 Chrome 进程： +mcp: node_repl/js started +mcp: node_repl/js (completed) +- File has a UTF-8 BOM (from Set-Content -Encoding UTF8 in Windows PowerShell 5.1).
