+# HPL Toolbox — Project Summary for AI
+
+## What this project is
+
+HPL Toolbox is an internal tool for a playable ad team. It ships as **two separate deliverables** from the same repo:
+
+1. **VS Code Extension** (`src/`) — a `.vsix` that adds tool panels as webview tabs inside VS Code.
+2. **Standalone Windows App** (`standalone/`) — a Go + WebView2 desktop app that exposes the same tools through a local HTTP server rendered in a native window. It is a **real, complete, production app** — not a prototype or subset.
+
+Both deliverables implement the same set of tools. New features are typically added to both.

+
+## Architecture notes
+
+### VS Code Extension
+- Each tool is a singleton webview panel (`singletonPanel` in `shared.ts`).
+- The panel HTML is returned as a template string from `getHtml()` inside each tool file.
+- Communication between extension host and webview uses `panel.webview.postMessage` / `onDidReceiveMessage`.
+- Settings are read from `vscode.workspace.getConfiguration('hplToolbox.*')` and contributed in `package.json`.
+- Session-persistent UI state (e.g. last selected server) uses `context.globalState`.
+
+### Standalone App
+- Go HTTP server on a random localhost port, served into a WebView2 window.
+- All pages return full HTML strings (no template files on disk).
+- Long-running operations (uploads, scans) use `newJSONStream` to stream NDJSON progress events — the browser reads these with `ReadableStream` and updates the UI incrementally.
+- Config is persisted to `%LOCALAPPDATA%\HPLToolbox\config.json` via `LoadConfig` / `SaveConfig`.
+- `localStorage` is used for lightweight UI-only state (e.g. last selected server in PLEC Upload).
+- Single-instance enforcement: on launch, tries to connect to a previous instance's port from a lock file and `POST /api/focus` to bring its window forward, then exits.
+
+### PLEC Upload — dual server detail
+- **Default (legacy)**: `POST http://167.99.227.249/src/upload_HTML_Experimental.php` with `fileUpload_N` / `iterationNameUpload_N` fields. Filenames are timestamped.
+- **Backup (WordPress)**: `POST http://20.255.60.183/wp-admin/admin-ajax.php` with `action=plec_upload_files`, `nonce`, `rows` (JSON array), and `file_N` fields. Login flow: POST `/wp-login.php` → GET `/file-upload/` to extract nonce. Iteration name is used as the uploaded filename. Preview URL is constructed as `/preview?theme=calcite&n1=<original>&m1=<saved>`.
+
+---
+
+## Build
+
+```powershell
+npm run build            # builds both .vsix and standalone .exe into dist/
+npm run build -- -Extension   # .vsix only
+npm run build -- -Standalone  # .exe only
+npm run run-standalone   # dev: go run . in standalone/
+npm run compile          # tsc only
+npm run watch            # tsc watch
+```
+
+Requires: Node.js, TypeScript (`npm install`), Go, optionally `vsce` and `rsrc`.
+

+
+## Key config (VS Code settings)
+
+All under `hplToolbox.*`:
+
+| Key | Default | Purpose |
+|---|---|---|
+| `plec.uploadUrl` | `http://167.99.227.249/src/upload_HTML_Experimental.php` | Legacy server endpoint |
+| `plec.originUrl` | `http://167.99.227.249` | Origin/Referer for legacy uploads |
+| `plec.wpUsername` | `pm` | WordPress username for backup server |
+| `plec.wpPassword` | _(set)_ | WordPress password for backup server |
+| `applovin.cookie` | _(empty)_ | `__Host-APPLOVINID` cookie for p.applov.in |
+| `deviceSimulator.devicesUrl` | Google Drive link | Remote devices.json URL |
+| `deviceSimulator.languagesUrl` | Google Drive link | Remote languages.json URL |

+# Mintegral Checker — TODO
+
+## Task Overview
+
+Build a local VS Code webview equivalent of the Mintegral PlayTurbo checker
+(`https://www.playturbo.com/review`). Validates a Mintegral playable ad ZIP against
+PlayTurbo requirements. Two check categories:
+
+- **Static** — parse `index.html` + ZIP structure without running the ad.
+- **Runtime** — load the ad in a sandboxed `srcdoc` iframe, inject a monitoring stub,
+  and detect whether lifecycle callbacks (`gameReady`, `gameEnd`, `gameStart`,
+  `gameClose`, `install`) actually fire.
+
+---
+
+## Finished
+
+- [x] Pure-Node ZIP parser (EOCD → Central Directory → Local File Headers, zlib DEFLATE)
+- [x] All 9 static checks:
+  - HTML Requirements (charset, viewport, single-file)
+  - CTA Method (`window.install` reference in scripts)
+  - Game End / Game Ready / Game Start / Game Close (regex on scripts)
+  - File Handling (no external URLs, base64 assets)
+  - File Spec (ZIP ≤ 5 MB, single `index.html`)
+  - Storage (no `localStorage.setItem` / `sessionStorage.setItem`)
+- [x] Device-frame simulator (phone mockup around `srcdoc` iframe)
+- [x] Event log panel showing runtime events as they fire
+- [x] Runtime timer with 60s timeout and per-check waiting badges
+- [x] `__ping__` handshake → "Simulator connected" in event log (confirms stub runs)
+- [x] Dual notification channels: polling `__hplMtgEvents` + `parent.__hplMtgNotify`
+- [x] `MW_INIT` interceptor (wraps `emitCheckData`, forces `_hasReview`/`_isPreview`)
+- [x] `window.postMessage` override (catches `previewer:gameReady` self-posts)
+- [x] `mkAccess` — `Object.defineProperty` accessor with undefined getter so AD's
+  `typeof window.gameReady === 'undefined'` guard passes, setter wraps assignment
+- [x] Capture-phase `load` safety net — wraps any SDK function declarations that
+  overwrote accessors, fires before `body.onload`
+- [x] Mute button UI (shows on ZIP load, hidden on reset, toggles Mute/Unmute label)
+- [x] Diagnostic lifecycle logging (`post-parse`, `DOMContentLoaded`, `load`,
+  `load+500ms`, callback assignment/call traces)
+- [x] AudioContext construction proxy for mute/unmute of closure-owned engine audio
+
+---
+
+## Bugs
+
+### 1. Callbacks never fire (critical, diagnostics added)
+
+**Symptom:** Event log shows "Simulator connected" (`__ping__` fires) but no lifecycle
+events appear. The same ZIP passes all checks on the real PlayTurbo site.
+
+**Root cause candidates (narrowed down but not confirmed):**
+
+A. **`body.onload` vs capture `load` ordering on `window`** — When the event target is
+   `window` itself, capture and bubble listeners both run at the "at target" phase in
+   registration order. Our stub is in `<head>` and registers first, so it should fire
+   before the body's `onload`. But this assumes no edge-case behaviour in VS Code's
+   Chromium sandbox / srcdoc context.
+
+B. **SDK function declaration closes over a local reference** — If the ad does:
+   ```js
+   var gameReady = function() { ... };
+   window.gameReady = gameReady;
+   ```
+   and `body.onload="gameReady()"` resolves to the local var (via closure), then
+   reassigning `window.gameReady` in our load-time wrapper has no effect.
+
+C. **CSP in VS Code webview blocks stub execution silently** — The webview panel has
+   an implicit CSP. The stub is injected into `srcdoc`; it might run in a restricted
+   context that prevents property interception or `parent` access for later events (even
+   though `__ping__` works because it runs synchronously at parse time).
+
+D. **Ad calls `gameReady()` before load** — If the ad boots via DOMContentLoaded and
+   calls `gameReady()` there (rather than body.onload), our load-event safety net fires
+   too late. The `mkAccess` accessor should still catch it, but only if the ad assigns
+   `window.gameReady` first.
+
+**What's been added:**
+- Injected diagnostic logging for lifecycle function `typeof` at post-parse,
+  DOMContentLoaded, load capture before/after wrapping, and 500 ms after load.
+- Logs callback assignment/wrapping and wrapper call paths to the event log.
+- Logs dynamic `document.createElement('script')` calls to help trace script injection.
+
+**What's still needed if callbacks still do not fire:**
+- Check if the ad bundles `preview-util.js` inside `index.html` or references it
+  externally (would fail file-handling check anyway).
+- Compare the diagnostic timeline against the real PlayTurbo execution path.
+
+---
+
+### 2. Mute button does nothing (fixed in monitor stub)
+
+**Symptom:** Clicking Mute/Unmute changes the label but has no audible effect.
+
+**Root cause:** The current approach searches `Object.keys(cw)` for an `AudioContext`
+instance. AudioContexts are almost always created in closures (inside Phaser or the ad
+IIFE) and are never assigned as window properties — `Object.keys` will never find them.
+`cw.Phaser.game.sound` also likely fails because Phaser stores the game instance
+internally, not at `window.Phaser.game`.
+
+**Fix applied:**
+Intercepts `AudioContext`/`webkitAudioContext` construction in the monitoring stub,
+stores captured contexts/gain nodes on `window.__hplAudioContexts` and
+`window.__hplMasterGains`, and routes `ctx.destination` through a master gain when
+possible. The mute button now sets captured master gain values first, then falls back
+to suspending/resuming captured contexts and exposed Phaser/global game sound objects.
+
+---
+
+## Improvements / Nice-to-Have
+
+- [ ] **Inject SDK alongside ad** — The real PlayTurbo checker loads `preview-util.js`
+  next to the ad. Bundling (or downloading once) the 265 KB SDK and injecting it into
+  the srcdoc would let `MW_INIT`/`emitCheckData` fire natively, which is the most
+  reliable callback path and matches what the real checker does.
+
+- [ ] **Diagnostic mode** — A "Debug" toggle that logs `typeof` of each lifecycle
+  function at key moments (post-parse, DCL, load, 500ms after load) to the event log,
+  making root-cause analysis faster.
+
+- [ ] **Replay button** — Reload only the iframe (not the full ZIP re-parse) to retest
+  without re-picking the file.
+
+- [ ] **Portrait / landscape toggle** — Flip the device frame aspect ratio.
+
+- [ ] **Multiple HTML entry points** — Some ZIPs have `playable.html` instead of
+  `index.html`; add a fallback search.
+
+- [ ] **Orientation lock detection** — Check for `screen.orientation.lock()` calls
+  (Mintegral requires the ad to handle both orientations).
+
+- [ ] **Version bump and changelog entry** — Once callbacks are working, bump to 0.1.8
+  and add a changelog entry for the Mintegral Checker tool.
+
+---
+
+## Known Issues / Constraints
+
+- VS Code `WebviewPanel` runs in a sandboxed Chromium process. `srcdoc` iframes are
+  same-origin with the webview, so `parent` access works — but the webview's implicit
+  CSP may still block certain APIs inside nested iframes.
+
+- The `Object.defineProperty` accessor approach (`mkAccess`) is the only way to let the
+  AD's `typeof window.X === 'undefined'` guard pass while still intercepting the
+  assignment. Any early concrete assignment (even `undefined`) breaks the guard in some
+  runtimes.
+
+- SDK `function` declarations at brace-depth 0 are `[[DefineOwnProperty]]` calls at
+  parse time; they overwrite our configurable accessors unconditionally. The load-time
+  safety net is the only recovery path for that scenario.
+
+- The `applyStaticResults` function sets `runtimeStatus = null` for lifecycle checks
+  that already failed statically. `handleRuntimeEvent` only transitions
+  `runtimeStatus === 'waiting'` → `'pass'`; it silently ignores `null`. This means a
+  static-fail check can't be runtime-rescued via the direct lifecycle path (though the
+  `handleSdkCheck` path does handle `null`). Intentional, but worth documenting.

+
+## Porting to a new project
+1. Update naming fields (3LC, vendor, concept name) in [scripts/build-all.mjs](scripts/build-all.mjs) — drives the output filename
+2. Update store URLs in [constants.ts](src/constants.ts) (iOS + Android)
+3. Adjust the Depth Map below to match the project's layer needs
+4. Update [iteration.ts](src/iteration.ts) A/B config shape for this project's variants
+5. Replace `Assets/` with project assets; update asset manifests in [BootScene.ts](src/scenes/BootScene.ts)
+6. Rewrite `game/` modules for the new mechanic(s) — keep the single-responsibility split
+7. Update this AGENTS.md's Depth Map and any project-specific pitfalls
+
+## Structure
+```

+scripts/build-all.mjs  # Single build → per-network HTML variants
+```
+
+### Responsibility split
+- **`game/`** modules each own a single concern (one mechanic, one widget, one system).
+  They receive the Phaser scene as a constructor arg and own their own game objects.
+  They never call ad-SDK functions (`triggerCTA`, `notifyGameX`, `trackEvent`).
+- **`GameScene.ts`** is the wiring layer: creates modules, passes data between them,
+  and calls SDK helpers at the correct lifecycle moments.
+- **`scenes/cta.ts`** owns end-card presentation and the store-redirect sequence.
+
+## Rules
+- 60 FPS target; never below 30 on mid-range Android
+- `dist/index.html` < 5 MB; WebP images, short audio
+- No hardcoded px — `sx()`, `sy()`, `sd()` only
+- No audio autoplay — unmute on first `pointerdown`
+- `for` loops in game logic; pool objects; no GC
+- `setDisplaySize(sd())` on images — never `setScale`
+- Never dim via `body`/page background
+
+## Phaser Config
+```ts
+{ type: Phaser.AUTO, transparent: true,
+  scale:  { mode: Phaser.Scale.NONE, width: 1080, height: 1920 },
+  render: { antialias: true, pixelArt: false } }
+```
+`Scale.NONE` — manual sizing; CSS = viewport px; internal = viewport × DPR.
+`antialias: true` — required to avoid jagged edges on scaled WebP assets (end-card logo, CTA, score pill). Never set to `false`.
+
+## Responsive (1080×1920 ref)
+```ts
+const s    = Math.min(viewW / 1080, viewH / 1920)
+const offX = (viewW - 1080 * s) / 2
+const offY = (viewH - 1920 * s) / 2
+// sx/sy/sd apply offX, offY, s
+```
+- `update()` polls `visualViewport` per-frame for rotation
+- On change: `game.scale.resize(vw*dpr, vh*dpr)` → `relayout()`
+- `bindResponsiveResize()`: rAF debounce + 100/300/600ms retries
+
+## CTA — SDK Priority (triggerCTA fallback chain)
+```
+1. ExitApi.exit()             → GoogleAds (gg)
+2. FbPlayableAd.onCTAClick()  → Facebook (fb) · Moloco (mo)
+3. Luna.Unity.Playable        → Unity (un)
+4. playableSDK.openAppStore() → (runtime fallback if SDK present)
+5. window.install()           → Mintegral (mtg)
+6. window.openAppStore()      → (runtime fallback)
+7. window.clickTag            → Moloco (mo) fallback
+8. window.__VUNGLE__          → Vungle (vu) via parent.postMessage
+9. window.__TIKTOK__          → TikTok (tt) → openAppStore() or window.open fallback
+10. mraid.open(url)           → Applovin (al) / Ironsource (is) / Unity (un fallback after Luna)
+11. window.open(storeUrl)     → Fallback (all others)
+```
+`notifyGameClose()` fires before every CTA redirect (all networks, no-op when SDK absent).
+MRAID CTA calls must be guarded: require `typeof mraid.open === 'function'`; treat missing `mraid.getState()` as `ready`; if state is still `loading`, fall through to `window.open(storeUrl)`.
+
+## Analytics — SDK Priority
+```
+ALPlayableAnalytics.trackEvent(e)  → Applovin (al)
+playableSDK.reportEvent(e)        → (runtime fallback if SDK present)
+console.log('[Analytics]', e)      → All other networks
+```
+Events: `DISPLAYED` · `CTA_CLICKED` · `ENDCARD_SHOWN` · `CHALLENGE_STARTED` · `CHALLENGE_SOLVED`
+
+## Game Lifecycle (all networks)
+`main.ts` exposes stubs on `window` so every network's preview tool detects them.
+Stubs only set if the SDK hasn't already provided its own (`typeof` guard).
+```
+gameReady()  → stub in main.ts; Mintegral also gets onload body attr from build
+gameStart()  → notifyGameStart() in GameScene.startPlaying()
+gameEnd()    → notifyGameEnd()  in GameScene.triggerFail() / triggerWin()
+gameClose()  → notifyGameClose() in cta.ts redirectToStore(), before triggerCTA()
+```
+
+### Pause / Resume / Mute (bindLifecycle in networks.ts)
+| Network | Mechanism |
+|---|---|
+| Unity | `luna:mute` / `luna:unmute` / `luna:pause` / `luna:resume` events; also shared MRAID exposure/viewability when `mraid.js` is present |
+| Mintegral | `window.message` → `onPause` / `onResume` |
+| Vungle | `ad-event-pause` / `ad-event-resume` events |
+| Applovin / Ironsource / Unity | MRAID 3.0 `exposureChange`, MRAID 2.0 fallback `viewableChange` / `isViewable`, and `audioVolumeChange` (gated in `initMraid`) |
+| GoogleAds / Facebook / Moloco | No SDK pause — browser handles visibility |
+
+### MRAID 3.0 Requirements & Best Practices
+MRAID networks are **Applovin (`al`)**, **Ironsource (`is`)**, and **Unity (`un`)**. All three must request `<script src="mraid.js"></script>` early in the generated HTML. Unity still uses Luna first for CTA/lifecycle where available, but MRAID must exist as the standards fallback.
+
+Creative requirements from the MRAID 3.0 spec and Best Practices Guide:
+- Request `mraid.js` as early as possible, exactly once, either with `<script src="mraid.js"></script>` or DOM insertion. Do not rely on the container to inject it automatically.
+- Wait for both DOM readiness and MRAID readiness before starting rich media behavior. Use `document.readyState` / `DOMContentLoaded` or `load` for the DOM side.
+- Use `mraid.getState()` together with `mraid.addEventListener('ready', ...)` so the creative still starts when the container fires `ready` before the listener attaches.
+- Guard access to `mraid` and MRAID methods with `typeof` checks. Treat missing optional methods as unsupported and fall back gracefully.
+- Use `mraid.open(url)` for MRAID clickthroughs. Avoid `<a href>`, `location.href` / `assign` / `replace`, and unguarded `window.open`.
+- Include `<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1">` or an equivalent mobile viewport tag.
+- Do not assume nested iframes can access native MRAID. If nested iframe access is required, the outer frame must provide its own bridge.
+- Use `exposureChange` as the MRAID 3.0 viewability signal, then degrade to `viewableChange` / `isViewable()` for MRAID 2.0 compatibility.
+- Listen for `audioVolumeChange`; `null` is valid and must be ignored. Only apply volume math when the value is numeric.
+- Listen for `error`; if the ad cannot run or assets fail, gracefully degrade or call `mraid.unload()` instead of showing a broken/blank ad.
+- Call `setResizeProperties()` before `resize()`. Do not use `resize()` for full-screen takeovers; use `expand()` for that case.
+- Avoid resizing or expanding interstitials. Check placement with `getPlacementType()` when one creative can serve inline and interstitial placements.
+- Avoid `useCustomClose()` and custom close indicators in MRAID 3.0. The host provides the close control.
+- Avoid two-part expandable ads (`expand(url)`); use self-contained one-part expandables.
+- Call `supports()` before optional/native features such as `storePicture`, `createCalendarEvent`, `getLocation`, VPAID, SMS/tel, or inline video behavior.
+- Use `playVideo()` for native video playback cases instead of `mraid.open(videoUrl)`. Use HTML5 `<video>` for inline playback when supported.
+
+Implementation requirements for `networks.ts` / `networks.js`:
+- Export `initMraid(timeoutMs = 2000, detectTimeoutMs = 500)` and call it at module load.
+- If `window.mraid` is missing at module load, poll briefly (`detectTimeoutMs`, default 500 ms) for late container injection before resolving as no-MRAID.
+- If MRAID exists and `mraid.getState() === 'loading'`, wait for `mraid.addEventListener('ready', ...)`; self-resolve after `timeoutMs` (default 2000 ms) so startup never hangs.
+- `main` / boot must `await initMraid()` before constructing `new Phaser.Game(...)`.
+- On setup, seed cached visibility from `mraid.isViewable()` when available.
+- Register MRAID callbacks once, before any Phaser scene is ready:
+  - `mraid.addEventListener('error', (message, action) => ...)` — log or gracefully handle failed/unsupported MRAID calls.
+  - `mraid.addEventListener('stateChange', state => ...)` — required when using state-changing MRAID behavior such as `close`, `expand`, or `resize`.
+  - `mraid.addEventListener('exposureChange', exposedPercentage => ...)` — MRAID 3.0 primary viewability. Pause when `exposedPercentage <= 0`; resume when positive.
+  - `mraid.addEventListener('viewableChange', viewable => ...)` — MRAID 2.0 compatibility fallback.
+  - `mraid.addEventListener('audioVolumeChange', pct => ...)` — only apply `pct / 100` when `typeof pct === 'number'`.
+- In `bindLifecycle(scene)`, apply cached hidden/non-exposed MRAID state immediately once a scene exists.
+- If the creative renders its own close control, wire that control to a guarded `mraid.close()` helper and call `notifyGameClose()` before closing.
+
+## Build
+Vite outputs IIFE format (`format: 'iife'`, `modulePreload: false`).
+Build script strips `type="module"` and `crossorigin` — ad networks reject ES modules.
+MRAID networks (`al`, `is`, `un`) inject exactly one `<script src="mraid.js"></script>` request.
+If built output contains `console.error` from Phaser or bundled node modules, prefer dropping it at bundle time instead of editing library source. Add this option to the shared Vite config, usually `vite.shared.js`:
+
+```js
+export default {
+  esbuild: {
+    pure: ['console.error'],
+  },
+};
+```
+
+Keep project-authored error handling meaningful: use visible fallback UI, `console.warn`, or guarded debug logging where needed.

+Networks marked **Zipped** ingest zipped creatives — [scripts/build-all.mjs](scripts/build-all.mjs) writes a `.zip` containing the HTML (one zip per variant, containing just that HTML at the root named index.html). Toggled per-network via `zip: true` in the `NETWORKS` array.
+
+Networks marked **Included** are built by default. Networks not marked are prepared for but not built. Toggle per-network via `included: true` in the `NETWORKS` array.
+
+Output is grouped by **iteration length** (e.g. `2words/`, `4words/`, `full/`) then by **network** (e.g. `Applovin/`, `Google/`, `Mintegral/`), with all per-network HTML or ZIP variants for that iteration sitting together inside the folder:
+
+`dist/<length>/<3lc>_<creative-type>_<vendor>_<concept-name>_<concept-num>_<gameplay>_<ugc>_<seasonal>_<lang>_<length>_<size>_<network>`

+- Gameplay start waits on a deferred-ready flag set when the secondary manifest finishes loading
+
+## Depth Map (adjust per project)
+Define depths as named constants in [constants.ts](src/constants.ts) — never use magic numbers in scene code.

+
+## Pitfalls
+| Issue | Fix |
+|---|---|
+| Rotation stuck | `Scale.NONE` + per-frame poll |
+| Mobile aliasing | Canvas = viewport × DPR |
+| FPS drop on resize | rAF debounce |
+| MRAID crash | `typeof mraid !== 'undefined'` guard |
+| Assets not inlined | `assetsInlineLimit: 100_000_000` |
+| Bundle > 5 MB | WebP q75, shorter audio |
+| Built output contains library `console.error` | If `console.error` comes from Phaser or bundled node modules, add `esbuild: { pure: ['console.error'] }` in `vite.shared.js` so it is dropped at bundle time. Do not edit library source. |
+| Audio blocked | Gate on `pointerdown` |
+| Letterbox | Avoid `Scale.FIT/EXPAND/CENTER_BOTH` |
+| CORS / module error | `format: 'iife'` + strip `type="module"` and `crossorigin` |
+| Network preview checklist fail | Expose lifecycle stubs on `window` + call `notifyX()` with `typeof` guards |
+| `playableSDK.reportEvent is not a function` | Applovin preview injects `playableSDK` without `reportEvent` — guard with `typeof playableSDK.reportEvent === 'function'`, not just `typeof playableSDK !== 'undefined'` |
+| iPhone black screen (Android works) | **Only one `Phaser.Game` per page, ever.** iOS WKWebView — used by Applovin/Ironsource preview apps and most in-app ad containers — caps or outright rejects the 2nd WebGL context. If a background scene is spun up as a separate `new Phaser.Game()` synchronously at module load, it can throw before `await initMraid()` and before the font promise resolves, so the rest of `main.ts` never runs → black screen with no visible error. Render the background as a CSS `background-image` on `#bg-container` (cover-sized) instead — zero WebGL contexts for the background, and nothing to throw at module-load time. iOS-debug path: enable Safari → Advanced → Web Inspector on the iPhone, connect to a Mac, open Develop → iPhone → preview WebView, read the Console. Without a Mac, temporarily install top-of-`main.ts` `window.addEventListener('error',…)` and `unhandledrejection` handlers that write the error into `document.body.innerHTML` so the failure is visible on-screen. |
+| iOS hangs on font load | `document.fonts.load()` silently stalls in WKWebView when `@font-face` uses base64 `data:` URLs. Race against a 1.5 s timeout: `Promise.race([Promise.all([…fonts]), new Promise(r=>setTimeout(r,1500))]).then(startGame)` |
+| iOS hangs on MRAID ready | `mraid.addEventListener('ready', …)` can miss the event if the container fires it before the listener attaches. `initMraid()` must self-resolve after ~2 s so `startGame()` always runs; also check `mraid.getState() !== 'loading'` first. |
+| External `src=` survives build | `vite-plugin-singlefile` only inlines assets *imported from JS*. A raw `<img src="src/assets/…">` in `index.html` ships as a literal relative path and fails in ad sandboxes, producing inconsistent per-device load failures. Leave DOM `<img>` elements with no `src`; assign via JS from `assets.ts` at boot (`setEndcardHtmlAssets()`). |
+| Audio keeps playing when ad hides | Add `visibilitychange` listener in the sound module — mute Phaser's sound system and `suspend()` the `AudioContext` when `document.hidden`, resume on return. Spec requires audio stop on hide/close. |
+| `mraid.open()` silently no-ops | Guard with `mraid.getState() !== 'loading'` before calling; fall through to `window.open()` if still loading. |
+| Previewer black screen with `Cannot read properties of null (reading 'appendChild')` in Phaser boot | Two compounding causes: (1) `vite-plugin-singlefile` hoists the bundled script into `<head>`, and the build strips `type="module"`, so the script runs **synchronously before `<body>` is parsed** — `document.body` is null. Wrap main.ts in a `DOMContentLoaded` gate (`if (document.readyState === 'loading') addEventListener('DOMContentLoaded', boot) else boot()`). (2) `parent: 'game'` (string selector) fails when the previewer sandbox strips custom DOM; create `<div id="game">` at runtime inside `boot()` and pass the **element reference** (not the string) to `Phaser.Game({ parent })`. The cascading `ScaleManager.resize → Cannot set properties of undefined (setting 'width')` errors all trace back to `game.canvas` never being created when either of these fail. |
+| NineSlice won't shrink in landscape | Phaser's `NineSlice` silently clamps its minimum dimensions to `(leftWidth + rightWidth) × (topHeight + bottomHeight)` **in source pixels**. Symptom: one UI chrome element stays huge in landscape while every other `sd()`-driven element rescales correctly — because the requested `sd(H)` is below the inset total. Shrinking the insets fixes the scale clamp but stretches the art's rounded corners. The right fix: **operate the NineSlice in source-pixel space and scale it uniformly with `setScale(sd(1))`**. Keep `setSize(wSrc, hSrc)` in source px so the center stretches horizontally with text growth while corners stay intact; the `sd(1)` scale is what makes the whole object shrink in landscape, bypassing the min-dim clamp entirely. When reading `this.preview.width` (which is in scaled px) to decide `wSrc`, divide by `sd(1)` to convert back to source space. Tween callers that reset `setScale(1)` also need updating — the bg's base scale is now `sd(1)`, not 1. See [SelectionLine.ts](src/game/SelectionLine.ts) for the pattern. |
+| Unity (un) submission: "not allowed to use window.top" | Luna's static scan flags the literal `window.top`, which Phaser 3 ships internally. In `build-all.mjs`, rewrite `window.top` → `window.self` for the `un` HTML only (other networks keep the original). Safe inside the playable's own frame because the iframe-vs-top check collapses to always-top. |
+| MRAID network missing `mraid.js` | MRAID 3.0 creatives must request `mraid.js` early. Inject `<script src="mraid.js"></script>` exactly once for Applovin (`al`), Ironsource (`is`), and Unity (`un`), even if the container may also expose runtime MRAID objects. |
+| MRAID listener wired too late | Previewers can probe MRAID before any Phaser scene is ready — if listeners are wired only inside `bindLifecycle` / scene `create()`, the creative can miss `ready`, `exposureChange`, or `viewableChange`. Fix: call `initMraid()` at `networks.ts` module-load time, guarded by `getState() === 'loading'` → `addEventListener('ready', setupMraid)` vs immediate call. Cache `_mraidViewable` / `_mraidExposed`; in `bindLifecycle` apply cached hidden/non-exposed state immediately. |
+| MRAID 3.0 `exposureChange` not handled | MRAID 3.0 containers dispatch `exposureChange` with `exposedPercentage` directly instead of — or in addition to — `viewableChange`. If only listening to `viewableChange`, the ad may never receive pause signals on newer AL/IS/Unity builds. Register both: `mraid.addEventListener('exposureChange', exposedPercentage => onExposure(exposedPercentage > 0))` and `mraid.addEventListener('viewableChange', onViewable)` inside `initMraid()`. Seed initial state from `mraid.isViewable()` on ready. |
+| MRAID 3.0 `audioVolumeChange` not handled | MRAID 3.0 containers fire `audioVolumeChange` with a volume level (0–100) or `null` when unavailable. Without a listener, the ad ignores host-level mute/unmute signals; if `null` is divided by 100, the ad can mute accidentally. Register `mraid.addEventListener('audioVolumeChange', v => { if (typeof v === 'number') scene.sound.setVolume(v / 100) })` in `initMraid()`. |
+| MRAID `error` listener missing | Validators expect failed or unsupported MRAID calls to be observable. Register `mraid.addEventListener('error', (message, action) => console.warn('[MRAID error]', { message, action }))` during early MRAID setup. |
+| MRAID `stateChange` listener missing | If the creative uses state-changing container behavior such as `mraid.close()`, `expand`, or `resize`, validators expect a `stateChange` listener. Register `mraid.addEventListener('stateChange', state => console.log('[MRAID stateChange]', state))` with the other early MRAID callbacks. |
+| Custom close control not wired to MRAID | If the creative renders its own close button, the button must call a guarded close helper: `notifyGameClose()` then `mraid.close()` when `typeof mraid.close === 'function'` and `mraid.getState() !== 'loading'`. Do not use CTA/install buttons as close controls. |
+| MRAID init not awaited before Phaser boot | If `new Phaser.Game()` is created before `initMraid()` resolves, the scene may fire `create()` before MRAID state is known — `bindLifecycle` then cannot apply a cached hidden/paused state. Make `boot()` async and `await initMraid()` before constructing the Phaser game. `initMraid()` must self-resolve after a timeout (~2 s) so a missing or non-firing MRAID container never blocks startup. |
+| Late MRAID injection not handled | Some containers inject `window.mraid` after the script executes — a synchronous `typeof window.mraid !== 'undefined'` check at module load returns false even though MRAID will be present. After the immediate check fails, poll briefly (~500 ms) before concluding no-MRAID, then proceed. |
+| Unsafe optional MRAID API calls | `useCustomClose()` was removed in MRAID 3.0, and APIs such as `expand`, `resize`, `storePicture`, and `createCalendarEvent` are optional/capability-dependent. Do not call them unless the project intentionally supports the feature and guards every call with `typeof mraid.method === 'function'` / `mraid.supports(...)` where relevant. |
+
+## Ironsource — Runtime Analysis
+Ironsource requires every `_is.html` build to pass **LevelPlay → Creative Management → Playable Workshop** (Runtime Analysis / Playable Validator) before launch. Skipping this can get the ad disabled. The validator runs in an iOS-like WKWebView sandbox and exposes console errors — use it as a free diagnostic channel for iPhone-only failures when a Mac + Safari remote-debug isn't available.
+
+## Moloco — Upload Checklist & CTA Implementation
+Creative specs: HTML5 (`.html` / `.htm`), < 5 MB, portrait + landscape.
+
+Before uploading to Moloco Ads, confirm all three:
+- [ ] No `XMLHttpRequest` anywhere in the ad (Moloco rejects it outright)
+- [ ] CTA calls `FbPlayableAd.onCTAClick()` with no parameters — Moloco uses this for store redirect (not `window.clickTag`)
+- [ ] No JavaScript redirects in ad file assets
+
+### CTA implementation options
+
+**Option 1 — event listener**
+```html
+<button id="ctaButton">Install</button>
+<script>
+  document.getElementById('ctaButton').addEventListener('click', function() {
+    FbPlayableAd.onCTAClick();
+  });
+</script>
+```
+
+**Option 2 — inline onClick**
+```html
+<button onclick="FbPlayableAd.onCTAClick()">Install</button>
+```
+
+Moloco's validator requires `FbPlayableAd.onCTAClick()` — this is why it shares priority #2 in the CTA chain with Facebook. `window.clickTag` is kept as a fallback at priority #7.
