Briefing
Intent: Production browser gaming portal: SvelteKit shell, 60+ embedded/native games, Nakama realtime, K8s/Agones backend. Guests and accounts play without installs.
Remaining: (1) A11y — residual warnings in isolated dev/theme tooling (e.g. Preview.svelte) if any remain after npm run check. (2) Per-game playability — see playability audit / E2E backlog. (3) CI — .github/workflows/frontend-check.yml runs npm run check plus scripts/validate-game-manifest.mjs on registered games only.
Pebble (/play/pebble) lens (2026-03-24): Production shell + iframe game shipped; games/pebble/CHECKLIST.md reconciled to “shipped + roadmap” SSOT. Bridge console.log / console.warn DEV-gated in games/pebble/src/lib/sdk/index.ts; funday-plugin.jsonversion → 2.1.0 (aligned with schemaVersion 2.1). Optional follow-up: confirm metadata.thumbnail (.png) vs assets/thumbnail.svg in publish pipeline.
Battle Cards (/play/battle-cards) lens (2026-03-25): Shell + solo experience solid. PvP:card_battle uses games/battle-cards/server/match_handler.ts (authoritative executeAction), client op 7 + op 6 deck, join-by-match-id + Quick match — deploy needs rebuilt nakama-modules. Play shell: Native mount reads host --dock-h for the hand strip (BattleArena bottom offset) so the hand clears GameDock when dock height changes. Visual polish shipped: PvP loading steps, turn emphasis, safe-area + dock-aware hand, combat log PvP note, VictoryModal stagger + prefers-reduced-motion, turn-transition reduced motion. E2E:frontend/tests/battle-cards.multiplayer.spec.ts — BATTLE_CARDS_PVP_E2E=1, optional BATTLE_CARDS_BASE_URL / BATTLE_CARDS_PATH. Remaining: automated matchmaking UX, reconnection, spectator (addendum). Kanboard: track PvP follow-ups (reconnect / spectator / matchmaking) as separate tasks when triaging multiplayer backlog.
Frogger (/play/frogger) lens (2026-03-24): Authoritative frogger_match + native FroggerGame.svelte; playability audit marks solo capture, multiplayer at-risk (no fresh 2P E2E). Solo regression e2e exists; monolithic client + any bridge props + possible lane-feel drift — see addendum below.
Quantified signal (frontend):npm run check (cwd frontend) → 0 errors (2026-04-04); warning count should be minimal (dev assets / theme generator only if present).

Games vanish from dev observatory after disable toggle
VALID_STATUS in AJV validator missing "offline" + getPluginById() filtered offline games
✅ RESOLVED (2026-04-21): Added "offline" to validator, hardened by-ID lookup + toggle endpoint. See bug-history.md
Root themes: Type surface was largest in dev tooling (theme generator, kanboard) — now fully resolved. Production shell (Navbar, GameCard, GameViewport) was always disciplined. Registry toggle bug (F8) fully resolved — 72 games, 0 errors.
Potential and salvage
Salvage:Very High. Architecture and deployment story documented. Static check is GREEN (0 errors). Nakama rebuilt with 12 handlers. 3 core games verified via smoke test.
Gems: Atomic build script, plugin JSON pattern, GameViewport bridge + theme param for iframe flicker, GameCard lazy images + aspect ratio, navbar aria-current on mobile links, games index aria-pressed on view toggles.
Remaining focus
A11y: Residual warnings (if any) after npm run check — mostly isolated dev/theme tooling; sweep when touching those routes.
CI:.github/workflows/frontend-check.yml runs npm run check plus scripts/validate-game-manifest.mjs when frontend/**, manifests, or the validator script change.

Live surface (fetched 2026-03-24):funday.gg/play/pebble renders site chrome, guest affordances, dock actions, and Game Feedback (0 open / 0 wip / 0 done + Add). Same pattern as other iframe-themeable titles; no evidence from static review alone of a Pebble-specific runtime failure.

games/battle-cards/server/match_handler.ts registered as card_battle in nakama-modules/index.ts — runs createBattleState / executeAction / checkWinCondition, broadcasts { type: 'state_update', battle } (op 1) and { type: 'game_over', winner } (op 2).
Client contract
nakama-client.ts: op 6{ cards } deck submit; op 7 JSON PlayerAction (server overwrites playerId).
Join flow
UI: Host PvP + Join with match ID (DifficultySelector.svelte); seat-aware HUD in BattleArena.svelte.
Engine portability
game-engine.ts uses JSON deep-clone instead of structuredClone for Nakama ES2017 target.
Deploy note: Run npm run build in nakama-modules/ and roll Nakama so the new handler is live; prod mismatch until then.

Forensic SSOT (per-game, full catalog): games/scribblaz/docs/2Fix_FLAWS.md — 22 tracked issues (F1–F22) with file anchors.
Play shell:frontend/src/routes/play/[id]/+page.svelte excludes scribblaz from auto-open lobby drawer (DRAWER_AUTO_OPEN_EXCLUDED_GAMES) alongside splix — immersive default; lobby remains on the dock.
Production Nakama handler: Shipped code is match_handler.ts bundled by nakama-modules/esbuild.config.mjs into nakama-modules/index.js. Legacy games/scribblaz/server/match_handler.js was removed (2026-03-24); games/scribblaz/server/.gitignore ignores it if regenerated.
Live surface:funday.gg/play/frogger loads the standard Funday play shell (nav, guest affordances, dock: Feedback / Fullscreen / Exit, Game Feedback kanban). Gameplay is native Svelte + canvas inside GameViewport, not visible in a static HTML-only fetch.
Intent (game):games/frogger/funday-plugin.json — Frogger Rush, solo practice + head-to-head (max 2), authoritative match frogger_match, tick rate 20 Hz (shared/types.tsFROGGER_CONFIG.TICK_RATE), leaderboards frogger_wins / frogger_rounds, lobby config.svelte.
Evidence elsewhere: docs/current/20260312_game_playability_audit.md — Frogger solo: capture, multiplayer: at-risk (not re-verified in that audit window). frontend/e2e/frogger-solo-regression.spec.ts — Practice, help collapse, game over → frogger_rounds submit + activity match loss; Chromium-only, no multiplayer path.
Top flaws (Frogger-specific):
ID
Symptom
Root cause
Fix vector
FG1
Hard to review or refactor safely
FroggerGame.svelte ~1700+ lines mixing render, input, socket, solo loop, UI
Run frogger-solo-regression.spec.ts (Chromium) after game edits
Solo regression gate; 2026-03-24 selectors updated for UI copy (Hop smarter, Round starts in, Play again, Close lobby after solo Play again autostart)
F1
2P manual or automated Nakama probe + update playability matrix
MP at-risk cleared or documented
F2
Narrow bridge types in FroggerGame.svelte
Fewer silent breakage on shell changes
F3
Split largest concerns out of FroggerGame.svelte (incremental)
Testable units, lower cognitive load
F4
Resolve or dismiss lane-speed feedback vs BASE_LANES
Consistent player expectations
Salvage:High for solo — manifest valid, shared types with server, e2e coverage. Medium for MP — handler exists in nakama-modules; verification and client maintainability are the main gaps.
MP verification gap (explicit): No repo e2e currently asserts two clients finishing a frogger_match round; treat multiplayer as proven only after a recorded probe or spec.
🛠️ Funday Dev Zone — Idiot Overstanding Cheat Sheet
Everything about frontend/src/routes/dev/ and frontend/src/lib/components/dev/
— what it is, how it works, what was done, and what the rules are.
🏗️ WHAT IS THE DEV ZONE?
Think of it as your private workshop inside the Funday platform.
It’s a set of internal developer pages at /dev/* with their own:
Net result: ~30 lines deleted, zero behavior change
🏛️ ARCHITECTURE RULES
🚧 Games Are Isolated
Games live in /games/ (not /frontend/)
They are pure HTML/JS bundles built by npm run build:games-static
The platform loads them inside <iframe> elements
Communication happens via FundayBridge (postMessage protocol)
The SvelteKit build (scripts/build-atomic.sh) does NOT build games
📡 Data Flow
+page.server.ts ──load()──→ +page.svelte via $props().data
│
├─ buildGameObservation() transforms raw game → rich observation
└─ summarizeGameObservations() aggregates for stats bar
🎨 Dev Theme (Independent)
Dev zone has its own theme (stored in localStorage as funday-dev-theme)
It does NOT affect the main platform theme
The data-theme attribute is set on the dev zone’s root div
33 DaisyUI themes available, default = “dark”
🗑️ KNOWN DEAD CODE

🧭 CONFIG REGISTRIES
devTools.ts — The Tool Registry
Every dev page is registered here with:
id, label, title, description
route (SvelteKit path)
group (ui-design, code-tools, backend)
icon (Lucide component)
badge, color, keywords
showInSidebar / showOnLanding flags
The sidebar reads this registry
The landing page reads this registry
The CommandPalette reads this registry
Adding a new tool page = add entry here + create route folder
devTheme.svelte.ts — Theme Persistence
Svelte 5 runes-based store (not old writable())
Uses $state internally with getter/setter pattern
Persists to localStorage via key funday-dev-theme
Exposes: .current (get/set), .themes (readonly array), .init() (call in onMount)
🎵 Notable Components
StickyPlayerBar.svelte (audio-assets)
Floating game dock with waveform visualization
Uses WaveSurfer.js for mini waveform rendering
Global keyboard shortcuts: Space=play, L=loop, A=autoplay, M=mute, ←→=seek
Scroll wheel on dock = volume control
100% Svelte 5 runes, props(),derived(), $effect()
CommandPalette.svelte
⌘K / Ctrl+K to open
Fuzzy searches all devTools + all DaisyUI component names
Arrow keys to navigate, Enter to go, Esc to close
Uses $bindable(false) for open state (parent controls it)
Indexes 17 dev tools + all component catalog entries
DeepChatWrapper.svelte
Dynamically imports deep-chat web component
Imperatively creates DOM element and configures it
Bridges DaisyUI CSS variables into the web component’s style API
Demo mode by default (no real AI backend connected)
🔒 HARD RULES (Violating = Build Breaks or Review Rejection)
🪄 Svelte 5 runes only — no $:, no on:click, no export let
🌼 No glassmorphism — no backdrop-blur, no bg-*/50, no glass
🏗️ Opaque hierarchy — use bg-base-{100,200,300} + shadow-* + border-*
🧩 DRY snippets — reuse {#snippet} instead of copy-pasting markup
🎯 TypeScript strict — typed props interfaces, no any (except legacy)
🚧 Games isolation — never import game code into SvelteKit, use FundayBridge
🔐 Private project — never push to GitHub or deploy externally
🧬 Volution vs. Evolution: Engine & Theming Breakdown
Objective: Demystify the structural differences between compiling Unity WebGL vs Native JS Physics, the mechanics of theming, and solving constraint tearing.
App
Engine
Paradigm
Math Magic
Volution
Unity WebGL (PhysX)
Compiled WASM
3D SpringJoint, TGS Iterative Solver
Evolution
Svelte + Matter.js
V8 JS Engine
2D Constraints, Iterative Math Hooks
🎨 1. Can DaisyUI Theme Volution (Unity)?
Short Answer: 🛑 Not inside the canvas out-of-the-box.
Deep Dive:
The funday-bridge injects DaisyUI CSS variables (--color-primary, etc) to the HTML document.documentElement. This perfectly themes the loading overlay, cards, and UI buttons.
However, Unity WebGL compiles to a closed WebAssembly pipeline, bypassing the browser DOM. The Unity Camera and Materials know nothing about CSS context.
How to solve it:
Create a FundayTheme.jslib plugin in the Unity project.
Expose a SetColors(string rgbPayload) method from JS to Unity C#.
Modify our TS bridge to detect unityInstance.SendMessage('ThemeManager', 'SetColors', ...) when a theme changes.
Write a Unity C# ThemeManager that updates RenderSettings.skybox and Material.color.
💥 2. Why do Evolution (Matter.js) creatures glitch / spasm?
In the Svelte implementation, you are witnessing Hub-and-Spoke Constraint Tearing.
Why it happens:
PhysX (Unity): Uses highly optimized Temporal Gauss-Seidel iterative solving for articulations. It can keep bones glued together even under massive pulling torque.
Matter.js (Svelte): Uses simple distance constraints (length=0, stiffness=1) to glue the Joint (Circle mass) to the Bone (Rectangle mass).
When the Neural Network fires the Muscle springs to twitch with intense force, those forces override the constraintIterations threshold of the solver.
The constraint “tears” (stretches). The solver detects the violation and blindly snaps the joints back together with overwhelming impulsive velocity. The result is runaway momentum ➔ Catastrophic spasming and explosions.
🛠️ 3. The Perfect Structural Fix
To stop the “spazm farts” and achieve Unity-level physics cohesion in JS:
🚀 Crank Solver Iterations: Double constraintIterations (24 ➔ 48) and positionIterations (16 ➔ 24) granting the engine more CPU cycles to finalize the math mathematically without snapping strings.
⚓ Mass Balancing: Increase minBodyMass to 0.5 preventing ultra-light joints from acting like buggy whips when slapped by gigantic limbs.
🌊 Hinge Damping: Introduce hingeDamping (0.1) so when a joint does tear infinitesimally, the snap-back energy is absorbed instead of ricocheting indefinitely.
The fix has been seamlessly integrated into games/evolution/src/engine/physics.ts! Enjoy spasmless evolution.
🎯 Core (Intent/Verdict/First Fix)
Intent: Pebble is a highly optimized, Svelte 5 (Runes) + Matter.js Peggle-like physics puzzle, designed to operate cleanly within the Funday platform as an iframe integration.
Verdict: Outstanding mechanical foundation and runtime efficiency. However, it suffers from “stubs” — most notably the LevelEditor and missing test suites. It also needs an expansion into competitive architecture (Multiplayer).
First Fix: Implement the actual visual logic of the LevelEditor. Adding this opens up rapid content generation without mutating TypeScript arrays.
💔 Reality (Tree/Flaws/Quantified Issues)
Tree Context:src/lib/game handles heavy physics, components/ handle views.
Flaws Count: 3 major functional gaps.
LevelEditor.svelte is a raw CSS drawer with ”🚧 Coming soon” placeholder. (Zero ROI currently).
E2E Playwright testing configured in package.json but completely absent from the actual directory structure.
No Turn-Based mechanics.
🛠️ Toolkit (Solutions/Rationales/Snippets)
LevelEditor.svelte Completion
Rationale: Leverage Svelte 5 and HTML Canvas to allow drag-and-drop coordinate mapping rather than manual math in levels.ts.
Phase 2: Playwright Suites - High ROI. Prevents physics engine rewrites from breaking playability.
Phase 3: Multiplayer Sync - Medium ROI. Turn-based Peggle creates huge player retention.

🎯 Verdict (Score 8/10 + top 3 critical fixes)
Verdict: Pebble is structurally elegant, with colors perfectly bound to funday-dark and CSS vars. However, its interactions lack the highly stylized, premium “Linear-like” polish that would wow users.
Top 3 Fixes:
Eliminate raw CSS .editor-panel and .editor-backdrop, refactoring with structured DaisyUI drawer and tailwind utilities for consistency.
Upgrade AttractScreen layout and buttons to integrate micro-animations (scale on hover) and magnetic feelings.
Enhance the Fever Rail to utilize real progress transitions and pulse logic with Semantic UI Contexts (Warning → Error).
👁️ Hierarchy (Visual weight map + corrections)
Current: The fever state rail sits cleanly on the right, but its icon (“thermometer”) and stats visually blend with the surrounding UI.
Correction: The Fever active state should create a glowing vignette around the whole canvas area or significantly pop the rail via Box-Shadow.
🎨 Design System (Color/type/spacing tokens—current vs fixed)
The raw CSS in components currently fights DaisyUI:
Current:background: rgba(15, 15, 25, 0.95);Fixed: Use bg-base-300/95 backdrop-blur-xl.
Eliminate arbitrarily calculated margins. Snap to the 4/8/16/24/32 grid scale universally in Svelte style blocks by converting to Tailwind classes.
⚡ Interactions (States/feedback/motion upgrades)
Apply Doherty’s law (<400ms feedback). Aiming a shot should have a subtle, responsive visual aid (e.g., an SVG dotted line trajectory) rather than relying completely on the mouse cursor crosshair.
Adding <div transition:fade={{ duration: 200 }}> across gameState toggles (Attract -> Playing -> GameOver) to prevent jarring frame swaps.
♿ Accessibility (WCAG gaps + exact fixes)
Gap: Dialogs and overlays trap pointer events but aren’t strictly trapping Tab focus.
Fix: Embed use:trapFocus actions on all overlays (LevelEditor, PauseOverlay) ensuring screen-reader capability and standard escape workflows.
🏎️ Perf-UX (Perceived speed optimizations)
The loading screen css-only spinner is fine, but coupling it with a brief CSS skeleton structure mimicking the game rail enhances perceived loading speed significantly.

Single Source of Truth (SSOT) for activity events and user statistics on the Funday gaming platform.
Overview
All activity and stats data flows through Nakama storage, ensuring consistency across:
Homepage “Live Activity” feed
Profile page stats and recent activity
/social activity tab
/dev/nakama Activity Workbench (debugging)
Canonical Types
Located in src/lib/types/index.ts:
ActivityEvent
interface ActivityEvent { id: string // UUID userId: string // User who performed/received activity type: "match" | "leaderboard" | "achievement" | "friend" | "social" | "system" gameId?: string // Optional game identifier result?: "win" | "loss" | "draw" score?: number durationSeconds?: number rank?: number title?: string // Human-readable for UI description?: string // Human-readable for UI metadata?: Record<string, unknown> createdAt: string // ISO timestamp}
UserStats
interface UserStats { gamesPlayed: number gamesWon: number gamesLost: number gamesDrawn: number totalPlayTimeSeconds: number favouriteGameId?: string achievements: number winRate?: number // 0-100 updatedAt?: string}
// Uses /api/social/activity which reads user_activity/recentconst res = await fetch("/api/social/activity")const { activity } = await res.json()
Migration Notes
Legacy: profile/+page.server.ts currently infers stats from leaderboards (slow, inaccurate)
Target: Read directly from user_stats storage (fast, accurate)
UserProfile.js / Leaderboard.js: Legacy client-side classes, not used in production

🎯 Verdict (Score 7.5/10 + top 3 critical fixes)
The foundation of the Svelte 5 Isometric Engine is strong, but the UI overlays lack the “quiet confidence” of premium interfaces. The HUD elements feel bolted-on rather than integrated, and the mobile controls float awkwardly without a cohesive grouping.
Top 3 Fixes:
Unify the HUD: Replace the bulky DaisyUI stats block and standard badge with sleek, minimalist glass pills.
Gestalt Grouping for Controls: Group the mobile D-pad controls onto a unified glass backdrop so they feel like a single cohesive controller rather than loose buttons.
Typography & Spacing Rhythm: Standardize the padding (4px grid) and reduce font sizes/weights to make the UI invisible until needed.
👁️ Hierarchy (Visual weight map + corrections)
Current: The “Isometric Engine” primary badge and the user badge compete for attention. The Camera stats block is visually heavy.
Correction: Group Title + Identity into a single, compact top-left glass pill. Shift the Inspector (Selected Tile) to the bottom-center to balance the screen weight.
🎨 Design System (Color/type/spacing tokens)
Colors: Shift from opaque bg-base-200/80 to native DaisyUI glass to inherit underlying terrain colors, softening the UI.
Spacing: Use strict Tailwind spacing (p-2, gap-2, mt-4).
Typography: Emphasize monospace (font-mono) for coordinates and precise data, while keeping labels muted (opacity-60, text-xs).
⚡ Interactions (States/feedback/motion upgrades)
Buttons: D-pad buttons need active:scale-95 to provide tactile tap feedback (Doherty threshold).
Tile Selection: The Inspector card should slide in smoothly (animate-in slide-in-from-right fade-in).
♿ Accessibility (WCAG gaps + exact fixes)
Focus: The D-pad buttons need clear focus rings for keyboard navigation (even if meant for touch).
ARIA: aria-label was added, but the D-pad could use an overarching aria-label="Movement Controls".
🏎️ Perf-UX (Perceived speed optimizations)
The UI is entirely absolute positioned with pointer-events-none on the wrapper, ensuring zero layout shifts (CLS = 0) when the game updates.

The game officially supports all individual versions of actively maintained desktop and mobile browsers with more than 0.2% global market share (>0.2% and not dead). Click “supported browser list” and check if your browser is supported. Upgrade your browser if it’s not supported.
Click to show a list of browsers tested to run or not run the game in 2021 (maybe outdated)
(*: presumed to work, but not fully tested)
🏆 Browsers based on Chrome’s engine, Blink, are fully supported by ArcoMage HD (as of 2021). With an average CPU / GPU, you should be able to play the game without performance issues. You don’t need the Desktop Version for these browsers:
Google Chromium
Google Chrome
Brave
Microsoft Edge (new version, from 2019)
Opera (from 2013) *
Android’s native browser / WebView *
Samsung Internet
Maxthon *
Vivaldi *
DuckDuckGo Privacy Browser
Kiwi Browser
Dolphin Browser
QQ Browser *
Sogou Browser *
Baidu Browser *
360’s browsers *
WeChat’s browser
Yandex Browser *
UC Browser *
CM Browser *
SRWare Iron *
Beaker *
Naver Whale *
Puffin Browser *
etc.
(If your Chrome-based browser has performance issues, the Desktop Version (a Chrome wrapper) will not help. Check solutions in What to do if the game is slow)
✅ Browsers based on Firefox’s Gecko, Safari’s WebKit, and Qt WebEngine rendering engines are tested and functional, but they may be slightly slower than Chrome-based browsers. This depends on your CPU / GPU. If you find these browsers slow, try the Desktop Version:
Firefox
Pale Moon *
SeaMonkey *
K-Meleon *
Tor Browser *
etc.
Safari 14+ (and/or iOS 14+) (v13- can run the game, but may not display WebP images)
Browsers based on Qt WebEngine
qutebrowser
Falkon
Dooble *
etc.
❌ Browsers with other rendering engines are not supported. You must switch to a Chrome-based browser or use the Desktop Version:
The game should function properly and maintain the correct layout on all modern mobile and tablet browsers.
To ensure the correct layout, users should rotate their devices to landscape mode (where the screen’s width is greater than its height).
The minimum supported screen size is 480 × 320 pixels. Devices with a width (or height in landscape mode) smaller than 320 pixels may not display the game optimally.
Performance
ArcoMage HD performs best on Chrome and other browsers based on the Blink engine. Based on a 2021 test and user feedback, there may be performance issues on Safari and Firefox. See browser compatibility details. If you encounter issues, users of Safari, Firefox, or Internet Explorer may want to consider using the Desktop Version. For performance optimization tips, check “What to do if the game is slow”.
Desktop Version
If you don’t experience performance or other issues playing ArcoMage HD in your browser, then you don’t need the current Desktop Version.
Some browsers, such as Firefox and Safari, which are not based on Chrome’s Blink engine, may experience slight slowness while running ArcoMage HD. In this case, you can opt for the Desktop Version.
The current Desktop Version is simply a Google Chrome browser-like wrapper that visits the URL https://arcomage.github.io/.
The first time you run the ArcoMage HD Desktop Version, it will silently download all images and sound files. Please allow about 1 minute (depending on your Internet speed) before you can disconnect from the Internet and play offline.
If both Google Chrome and the Desktop Version are installed, the Desktop Version will have its own independent storage. Clearing data in Google Chrome will not affect the Desktop Version’s settings.
The current Windows Desktop Version is not expected to be updated. MacOS and Linux versions of this Electron-powered app are not planned. However, Tauri may be used to build future cross-platform and lightweight desktop and mobile apps of the game. (issue page)
Fullscreen Mode
Whether using the PWA or not, some mobile browsers may not remove the top and bottom bars in fullscreen mode, but this is usually configurable.
Multiplayer Mode
If you encounter any issues related to Multiplayer Mode, please refer to the § Multiplayer Mode section in the main readme.
In rare cases, depending on network conditions and other factors, users may experience difficulties connecting to other players, even if there are no NAT issues (issue page). Currently, we are unable to replicate the issue, and the only suggestion is to try again later.
Key Fix: AI Stale-Index (Root Cause of “Game Stalls After Round 1”)
playAITurn() planned ALL card plays + attacks from a single snapshot. After each splice(),
indices became stale → wrong cards played → silent failures → game hangs.
Fix: Re-snapshot + re-plan after EACH action. See docs/archive/bug-history.md.

🚢 Battleships – Game SSOT
Game ID:battleships
🧩 Overview
Battleships is a classic naval strategy game with intelligent AI and support for multiplayer battles.
Players: 1–2
Mode: Turn-based board game, single-player vs AI and multiplayer-ready
Integration Type:iframe-themeable
Entry Point:index.html
Status: ✅ Fully compliant and production-ready from a containment + leaderboard perspective; one remaining runtime issue tracked in the game’s checklist.
This document is the single source of truth for Battleships as deployed on the Funday platform.
Exposed through /api/leaderboards/… endpoints and covered by Playwright tests.
Per the GAME-AUDIT-LOG entry, Battleships is fully compliant with:
Manifest validation.
Containment checks (no $lib imports, no cross-game imports).
Leaderboard wiring and API coverage.
📊 Implementation Status & Outstanding Work
Summarized from games/battleships/docs/development/CHECKLIST.md and the audit log:
✅ Localhost development passes with good visuals and accessibility.
✅ Build system converted from SvelteKit to standalone Vite/HTML setup.
✅ Manifest updated for entryPoint: "index.html" and leaderboards.
✅ Containment and leaderboard checks pass.
❌ There is a known production runtime error related to the Svelte mount/JS init sequence in the iframe context (see Battleships checklist for details and migration options).
The recommended long-term architecture (per the checklist) is to stabilise Battleships as a pure vanilla HTML/JS game similar to other iframe games like memory, removing Svelte/Vite complexity once the migration is done.
🔭 Planned Work (High-Level)
See games/battleships/docs/development/CHECKLIST.md for detailed phases; high-level bullets:
Stabilise Architecture – decide between fixing the Svelte mount error vs. migrating to a vanilla HTML/JS implementation and document final decision.
Guest & Identity Regression Audit – re-verify guest flows and identity integration after deployment changes.
Screenshot Proof Automation – add Playwright-based screenshot proof for /play/battleships.
Verification & Documentation – update checklist and relevant docs once deployment is stable.
This SSOT doc should be updated whenever the architecture decision is finalised or when the runtime error is resolved.
perfect complete and polish Bombergang
You are taking over Bombergang integration revamp in /home/usr/funday.
Your mission: triple-check, finalize, and polish to 100% completion without regressions.
1) What is already implemented (do not regress)
No-lobby, match-first iframe flow
Bridge bootstrap + match/session/theme handling in Bombergang iframe.
3) Clean-streamlined completion criteria (Definition of Done)
No-lobby Bombergang flow is stable in live Funday drawer/viewport.
Theme sync works dynamically with host theme changes.
Full-bleed embed UX has no legacy UI artifacts.
Match-scoped server routing is isolated and cleanup-safe.
No regressions in multiplayer drawer/store behavior.
Final evidence delivered as:
concise verification checklist,
exact pass/fail results,
any remaining risk (if any) with file-level pointers.
4) Guardrails
Do not reintroduce internal Bombergang lobby UX into primary flow.
Do not alter core game loop semantics unnecessarily.
Keep edits surgical, clean, and minimal.
Private project rule applies: no publishing/deploying to public repos.
If everything passes, provide final signoff as: “Bombergang integration is streamlined, fully match-first, theme-synced, cleanup-safe, and production-ready.”

§8: Dev cards — max 1/turn, can’t play same turn bought
Status: “Phase 0: Architecture Rescue” complete. Base game logic is functional.
Location: games/catan/index/
2. Architecture
The project follows a clean separation of concerns:
Core Logic (src/lib/game/)
GameController.ts: The central brain. Handles high-level actions (roll, build, trade) and orchestrates extensions.
GameState.svelte.ts: Uses Svelte 5 $state rune to create a global, reactive game store. This is the “single source of truth”.
ExtensionRegistry: A powerful pattern allowing modular game rules. BaseExtension implements standard rules, while SeafarersExtension (and future ones) can inject hooks for custom logic.
opcodes.ts: Defines the network protocol for multiplayer synchronization via Nakama.
UI Components (src/lib/ui/, src/lib/board/)
HexGrid.svelte: Renders the game board using SVG. Efficient and scalable. Handles clicks on Hexes (Robber) and Vertices (Building).
BuildingControls.svelte: The main interaction hub for the player.
PlayerHud.svelte: Displays resources and stats.
3. Svelte 5 & Runes Usage
The project is fully embraced Svelte 5 runes:
$state: Used in GameState.svelte.ts for deep reactivity of the entire game state.
$derived: Used in HexGrid.svelte to efficiently calculate vertex positions only when hexes change.
$props: Used for component props.
$effect: Used in App.svelte for side effects like map generation and lobby logic.
Verdict: The Svelte 5 implementation is modern and follows best practices.
4. Intuitive Gameplay Analysis
The current implementation provides a solid functional foundation, but there is room for “Game Feel” improvements.
✅ What’s Working
Clean Visuals: SVG board is crisp and responsive.
Reactive UI: HUD updates instantly when resources change.
Clear Constraints: Buttons disable when you can’t afford items.
Multiplayer: Network sync is built-in from the start.
🚧 Areas for Improvement (The “Juice”)
Interaction Model: Currently relies on “Click Button -> Click Board”.
Recommendation: Implement Drag & Drop. Dragging a road from the HUD to the board feels much more tactile and intuitive.
Visual Feedback:
Recommendation: Add Ghost Buildings. When hovering a vertex in build mode, show a semi-transparent settlement to preview the action.
Recommendation: Animations. Resources should “fly” to the player’s hand. Dice should roll visually.
Phase Clarity:
Recommendation: A more prominent Phase Indicator (e.g., “Roll Phase”, “Trade Phase”) to guide the player through the turn.
Map Interactivity:
Recommendation: Highlight valid build locations more aggressively when in build mode.
5. Roadmap for “Intuitive Perfection”
To take this from “Functional” to “Delightful”:
Refine Building UX:
Add “Ghost” previews on hover.
Implement Drag & Drop (using HTML5 DnD or a lightweight library).
Add Visual Polish:
Animate Dice.svelte.
Add CSS transitions for resource count changes.
Enhance Feedback:
Show floating text (“+1 Wood”) on hexes when dice roll matches.
Add sound effects for key actions (build, roll, trade).
6. Key Files to Watch
src/lib/game/GameController.ts: If you want to change rules.
src/lib/board/HexGrid.svelte: If you want to change board interaction.
src/lib/ui/BuildingControls.svelte: If you want to change player actions.
🎯 Briefing: Catan “Everything” Engine
Intent: Transform a monolithic Base Game implementation into a modular “Kernel + Extension” engine capable of running Settlers, Seafarers, Cities & Knights, and Scenario packs simultaneously.
Top Flaw: GameController.ts is a partial God Class. It delegates some logic (Harvest/Cost) but retains execution logic (Turn phases, Robber movement, Dev Card execution) that needs to be hooked for expansions.
First Fix: Complete the hook system for canBuild, moveRobber, and playDevCard.

External best-practice notes used
DaisyUI 5 upgrade guidance confirms semantic fieldset/legend form pattern and recommends semantic-first form controls.
DaisyUI docs support spinner/skeleton components; skeleton is preferable for longer contextual loading blocks.
Proceed with Phase A + B together for the best value burst: visible polish, reduced cognitive load, and improved mobile usability without touching simulation core logic.

🚀 Evolution preset comparison in single-creature mode
You are taking over Evolution validation.
Objective
Run a clean comparison across 3 creature presets with population size = 1 (and batch size = 1) so each run clearly reflects one preset’s behavior without crowd/noise from multiple creatures.
Why this is needed
Current visuals can look unlike a preset when many creatures overlap/mutate in parallel. We need deterministic, apples-to-apples preset comparison in single-creature mode.
Relevant code context

🟢 Status (2025-11-22) — LEGACY NOTE
The critical flaws described below reflect the pre-refactor iframe implementation.
Treat the analysis and blueprint below as historical forensics and design notes.
🎯 Briefing
Intent:fungame is intended as a minimal, complete, and portable example of a Funday platform game integration, demonstrating key features like guest authentication, matchmaking, and leaderboards.
Top Flaws:
State Management: Heavy reliance on global variables creates unpredictable state and race conditions.
Matchmaking: A dual-path system (API vs. direct Nakama call) fragments the player pool and creates an inconsistent user experience.
Leaderboards: The write path (via platform bridge) and read path (direct API call) are disconnected, causing scores not to appear.
First Fix: Refactor the matchmaking logic to use a single, reliable path through the Nakama client.

🐛 Flaw Forensics
1. Dual-Path Matchmaking
Root Cause: The btn-match handler in ui.js attempts to join a match through two conflicting mechanisms:
Platform API:POST /api/matches
Direct Nakama SDK:conn.joinOrCreateMatch('fungame')
This creates a scenario where some players join via the platform’s logic and others join a generic “fungame” match directly, effectively splitting the player base and making it seem like matchmaking is broken.

else API Fails
FunGameUI->>Nakama: joinOrCreateMatch('fungame')
Nakama-->>FunGameUI: { matchId: "nakama-direct-456" }
end
2. Disconnected Leaderboard Flow
Root Cause: The game writes scores via bridge.submitScore() but reads them from /api/leaderboards/fungame_highscore. This assumes the bridge and the API are perfectly in sync. The CHECKLIST.md confirms this is a known issue, likely due to the leaderboard not being created or the bridge event not being correctly handled by the host.

✨ Potential & Salvage
Core Logic: The game loop (game.js) and socket lifecycle management (lifecycle.js) are solid and can be reused.
Bridge Integration: The FundayBridge provides a good abstraction layer, but the game should not depend on it for core gameplay functionality like matchmaking.
Salvageable: ~80% of the code is salvageable with refactoring.
🛠️ Rescue Blueprint
Phase 1: Stabilize Core Nakama Integration
Create a Centralized State Manager:
Create src/state.js to encapsulate all shared state (auth, connection, match data).
Refactor fungame.js to use the state manager instead of global variables.
Unify Matchmaking Logic:
Remove the /api/matches call from ui.js.
Standardize on using conn.joinOrCreateMatch() with a properties query to find suitable matches.
Update the UI to reflect the unified matchmaking flow.
Fix Leaderboard Flow:
For now, bypass the bridge for score submission and write directly to Nakama from the game client to ensure a working loop.
Add a check to ensure the fungame_highscore leaderboard exists, and log a clear error if it doesn’t.
Phase 2: Decouple from Host
Refactor Authentication:
Simplify the ensureAuth flow to rely solely on the FundayAuth SDK, removing the complex fallback to the host-provided session.
Isolate Bridge Dependencies:
Move all bridge calls into a dedicated src/bridge-facade.js module. This will make it clear which parts of the game interact with the host and simplify testing.

🎮 Fun Game Template — Features & Integration Guide
A minimal-yet-complete game template to validate the entire Funday platform flow. Use this as a reference starter for future games or as a testing playground.
Multiplayer scaffolding (join/create match via Nakama socket)
Embed-mode friendly layout and full-bleed canvas
Safe-by-default 🧯 Error Handling and message replay
🧭 End-to-end platform flow (TL;DR)
/play/fungame loads plugin metadata and emits playUrl?embed=1, so the host keeps the unified shell while pointing an iframe at /games/assets/fungame/index.html.
GameViewport.svelte mounts the iframe, calls createHostBridge, and sends a funday:handshake + theme/locale/session injections. The bridge enforces origin rules and times out if the game never ACKs.
fungame.js boots, instantiates FundayBridge, registers callbacks for theme/locale/session/dock actions, and responds with funday:ack followed by game:ready, which flips the HUD to “Ready” and wires dock actions.
Player actions drive cross-surface features: score submits call bridge.submitScore('fungame_highscore', score) → /api/leaderboards/submit → Nakama leaderboard; analytics fire through bridge.analytics(...) → /api/analytics/track → Nakama storage.
Multiplayer buttons ensure a guest device session via FundayAuth, open a Nakama socket with createNakamaConnection(), then joinOrCreateMatch('fungame'); lifecycle hooks auto-reconnect, rejoin from localStorage, and emit analytics for reconnect events.
Exiting or dock interactions (pause/resume/reset/fullscreen) round-trip through the bridge so the host shell remains authoritative for navigation, fullscreen, and GameDock state.
🗺️ Paths that matter
Game root: /games/assets/fungame
Play route: /play/fungame (keeps global Navbar/HUD)
Host origin validated by platform; game should only talk to parent
Keep game self-contained; use platform paths for assets and SDK
Avoid inline eval or dynamic script insertion
🧪 Local sanity checklist
/games/assets/fungame loads index.html
/games/assets/_sdk/funday-bridge.js is reachable
/play/fungame renders with Navbar/HUD + Dock; actions work
Score submit triggers platform event and Nakama write
Joining a match succeeds (socket connected)
Playwright spec frontend/e2e/fungame-smoke.spec.ts now asserts leaderboard refresh responses after score submit, so keep /api/leaderboards/fungame_highscore healthy before CI runs.
🧭 Migration tips (from legacy)
Replace window.parent.postMessage patterns with FundayBridge
Stick to embed=1 for platform play; avoid building your own chrome
Prefer platform HUD/Dock for common controls

<!-- index.html (fungame) --><script src="https://cdn.jsdelivr.net/npm/@heroiclabs/nakama-js/dist/nakama-js.umd.js"></script><script src="/games/assets/_sdk/funday-auth.js"></script><script type="module"> import { createNakamaConnection } from "/games/assets/_sdk/funday-nakama.js" async function main() { // 1) Ensure guest session const auth = new window.FundayAuth() const { client, session, user } = await auth.createAuthenticatedClient() // 2) Create socket and connect with retry const conn = await createNakamaConnection(session.token) await conn.connectWithRetry(3) // 3) Join or create a tiny match const matchId = await conn.joinOrCreateMatch("fungame") console.log("joined match", matchId, "as", user.username) } main().catch(console.error)</script>
🧩 Auth & Session (Guest-first)
Device session via FundayAuth (guest auto-creation, persisted device id) is the primary path in fungame.
When FundayAuth is not available or fails (e.g. degraded/test environments), fungame’s ensureAuth helper can fall back to a host-provided session/token so the demo still works, but this path should be treated as secondary.
One client+session per tab; reuse until expiry; on expiry, re-authenticate device
Keep tokens out of logs and UI
// Guest session with user infoconst auth = new FundayAuth()const { client, session, user } = await auth.createAuthenticatedClient()// session.user_id, session.expires_at; user.id, user.username
🔍 Auth verification (manual check)
For a quick manual verification using raw HTTP (no game UI), you can:
Call a simple Nakama endpoint with that token, for example listing the current account:
curl -X GET "http://127.0.0.1:7350/v2/account" \ -H "Authorization: Bearer YOUR_DEVICE_SESSION_TOKEN_HERE"
If both calls succeed, you have a valid guest device session that matches the expectations of fungame’s ensureAuth helper and the Nakama JS examples from games/nakama-tests/nakama-js.md.
Tips
Persist a stable device_id (already handled in funday-auth.js)
Treat expiry as normal → re-run authenticateDevice
Avoid exposing server keys in game code (helpers handle env)
🧠 Client & Environment
Client construction is handled in helpers. For direct usage:
async function reconnectWithBackoff(max = 5) { for (let i = 1; i <= max; i++) { const delay = Math.min(1000 * Math.pow(2, i - 1), 8000) try { // update UI to paused/offline setStatus(`reconnecting… attempt ${i}`) await socket.connect({ token: session.token }, false) setStatus("online") return true } catch (e) { console.warn("[nk] reconnect failed", i, e) await new Promise((r) => setTimeout(r, delay)) } } setStatus("offline") return false}socket.onclose = () => { setStatus("offline") reconnectWithBackoff(5)}window.addEventListener("online", () => reconnectWithBackoff(3))window.addEventListener("offline", () => setStatus("offline"))
Rejoin on reconnect (persist+rejoin)
// Persist current matchId when joiningconst MATCH_KEY = "fungame.current_match_id"socket.onmatchmakermatched = async (matched) => { const match = await socket.joinMatch(matched.token || matched.match_id) localStorage.setItem(MATCH_KEY, match.match_id)}// After a successful reconnect, attempt rejoin if still validasync function onReconnected(conn) { const saved = localStorage.getItem(MATCH_KEY) || "" if (saved) { try { await conn.socket.joinMatch(saved) console.log("rejoined match", saved) } catch (e) { // Match ended/unavailable: clean up localStorage.removeItem(MATCH_KEY) } }}
Fungame relayed flow (reference)
In fungame, the full relayed flow looks like this:
Auth: FundayAuth creates/ensures a guest device session and exposes { client, session, user }.
Socket connect: createNakamaConnection(session.token) + connectWithRetry(3) opens a single socket per tab.
Match join/create: joinOrCreateMatch('fungame') finds or creates a small relayed match by label.
Gameplay: match data flows over the socket; UI shows match: <id> status.
Disconnect: onclose marks status offline and starts reconnect with bounded backoff.
Reconnect: a new socket is created, connectWithRetry is called again, and status shows reconnecting… (#n) → reconnected.
Rejoin: after a successful reconnect, the saved MATCH_KEY is used to joinMatch(saved) and status becomes match: <id> (rejoined).
The Playwright spec frontend/e2e/fungame-reconnect-rejoin.spec.ts asserts this behaviour by forcing a socket close and verifying that the match id after reconnect still matches the original one.
🤝 Match Flow (join or create)
// Helper path used by fungameconst matchId = await nk.joinOrCreateMatch("fungame")// Internals: listMatches(...) by label → join first suitable → create otherwise
// records around the current userconst around = await client.listLeaderboardRecordsAroundOwner( session, "fungame_highscore", user.id, 5,)// around.records → neighbors centered on the player
Tips
Keep one primary board per mode; add weekly/daily boards only when needed
Keep values small and serializable; avoid large arrays
Use deterministic keys where you need overwrites; timestamp keys for logs
For fungame analytics, events are typically written into the game_analytics collection with keys like fungame-<timestamp>. The snippet above is the canonical readback recipe: list objects from game_analytics for the relevant user to inspect fungame events.
Server: fungame_echo RPC (registered in nakama-modules/index.ts) accepts a JSON payload like { score: number } and responds with { success, message, score, t }.
Client: the “Call RPC” button in fungame calls this RPC with the current score and shows a toast based on success or error.
socket.onnotification = (n) => { /* show toast */}// Chat/channel basics (create/join/send varies by app model)
Fungame-specific lobby chat
Room: Room:fungame:lobby (chat type 1, room).
Client joins this room via socket.joinChat('Room:fungame:lobby', 1, true, false) when the “Join Chat” button is clicked.
Messages are sent with socket.writeChatMessage(channel.id, { text }) and rendered into a tiny in-game chat panel.
🧯 Errors, Retries, and Reconnects
async function retry(fn, attempts = 3) { let last for (let i = 1; i <= attempts; i++) { try { return await fn() } catch (e) { last = e await new Promise((r) => setTimeout(r, 250 * i)) } } throw last}
Patterns
Session expiry → re-authenticate device; refresh UI state
Socket drop → show paused/offline; retry connect with backoff
Don’t fork SDK helpers per game (keep platform-managed)
🧭 Where this plugs into platform
Play route /play/fungame keeps Navbar/HUD + Dock; iframe is same-origin sandbox
Bridge injects theme/locale/session; you notify Ready, setNav, setDock
Asset server serves /games/assets/... with ?embed=1
🎯 Fun Game Nakama Integration — Practical Cheat Sheet
Minimal, production-ready patterns to wire a browser game to Nakama via the Funday platform. Copy/paste friendly.
🔌 Session & Client
Use FundayAuth to guarantee a guest device session (primary path)
When FundayAuth is unavailable or fails, fungame can fall back to a host-provided session/token (as seen in ensureAuth in games/fungame/fungame.js), but guest device auth remains the recommended default pattern.
Prefer the platform-provided host, port, SSL
Keep a singleton client+session per tab
<script src="/games/assets/_sdk/funday-auth.js"></script><script> // window.FundayAuth available async function ensureAuth() { const auth = new FundayAuth() const { client, session, user } = await auth.createAuthenticatedClient() return { client, session, user } }</script>
🔄 Socket & Matchmaking
Use helper to open a socket using the session token
socket.onmatchdata = (md) => { const op = md.op_code // server-defined // parse md.data (Uint8Array) to JSON if needed}socket.onclose = (ev) => { // update UI, allow reconnect}
🧯 Error Handling
Treat network failures as normal; retry with small backoff
Provide clear UI state transitions
async function retry(fn, attempts = 3) { let last for (let i = 1; i <= attempts; i++) { try { return await fn() } catch (e) { last = e await new Promise((r) => setTimeout(r, 250 * i)) } } throw last}
🔐 Security Notes
Never embed server keys in game logic (use env in SDK helpers only)
Avoid eval and dynamic script injection
Validate all incoming socket payloads before trust
🧪 Local Sanity Checklist
Session created (guest) and user ID visible
Socket connects and match join succeeds
Score submissions visible in platform + Nakama
No console errors; reconnection is graceful

Project Overview
“Life” is a browser-based evolution game made for GMTK Jam 2024. Players start as a small cell and evolve through increasingly complex organisms (blobs → worms → fish). All graphics are procedurally generated - no graphical assets are used.
Commands
pnpm dev # Start development serverpnpm build # Build for productionpnpm preview # Preview production build
Architecture
Core Systems
Engine (src/engine.ts): Game engine wrapper around PixiJS. Manages the render loop, physics world (Rapier2D), camera system with smooth interpolation, and container hierarchy (mainContainer → zoomContainer → stageContainer). Exposes globals: engine, camera, physicsWorld, addChild().
Game (src/game.ts): Main game class. Manages levels, player, particles, background, and narration. Handles evolution progression and music transitions based on player level.
Level (src/Level.ts): Spawns and manages NPC organisms. Each level corresponds to an organism size tier. Levels dynamically load/unload based on player proximity.
Player (src/Player.ts): Handles player input (A/D keys or mouse), evolution upgrades, and eating mechanics. The upgrades array defines organism transformations at each level.
Organism System
Organism (src/organisms/Organism.ts): Base class for all creatures. Handles movement, collision groups (via Rapier2D), hunting/hunted behavior, and physics body management.
BlobOrganism: Simple circular organisms with procedural wiggle deformation using noise. Used for early evolution stages (levels 0-3).
WormOrganism: Multi-segment creatures using Body/Chain for procedural animation. Segments follow the head with angle constraints.
FishOrganism: Complex organisms with fins (pectoral, ventral, dorsal, caudal), eyes, and optional patterns (stripes, points). Uses same Body/Chain system.
Procedural Animation
Chain (src/base/Chain.ts): Inverse kinematics chain for creature spines. Uses angle constraints to limit joint rotation. The resolve() method propagates position from head to tail.
Body (src/base/Body.ts): Draws smooth body shapes around a Chain spine using quadratic curves. Handles body width interpolation and eye rendering.
Key Dependencies
pixi.js: 2D rendering
@dimforge/rapier2d: Physics (WASM-based)
pixi-filters: Visual effects (blur, bloom)
@texel/color: OKLCH color space conversions
simplex-noise: Procedural noise for movement and deformation

Role: You are a Heroic Labs Nakama Architect (TypeScript Runtime).
Task: Build a production-grade, Server-Authoritative Memory Game with a “Lobby-to-Game” flow.
Here is the Absolute Zenith of Nakama architectural guidance. This is the “Senior Principal Engineer” level breakdown. It assumes you want maximum performance, zero cheating, and a seamless UX.
🏗️ The Architecture: “The Airlock Pattern”
To achieve “Lobby -Game” seamlessly, we use the Airlock Pattern.
The Lobby (RPC): Not a match. It’s a stateless RPC request that reserves resources.
The Handoff: The RPC spins up the Match and returns the MatchID.
The Game (Authoritative): The persistent loop where the magic happens.
The Data Flow (Visual)
graph LR
A[Client A] -->|1. RPC: CreateMatch| S[Nakama Server]
S -->|2. nk.matchCreate| M[Auth Match (Paused)]
S -->|3. Return MatchID| A
A -->|4. Socket: Join MatchID| M
B[Client B] -->|5. Socket: Join MatchID| M
M -->|6. Both Present?| G[State: START GAME]
🧪 The “God-Mode” Prompt
It contains constraints that force the AI to use advanced Nakama patterns (Presences, OpCodes, Tick-Rate Optimization).
Role: You are a Heroic Labs Nakama Architect (TypeScript Runtime).
Task: Build a production-grade, Server-Authoritative Memory Game with a “Lobby-to-Game” flow.
Technical Constraints:
Runtime: TypeScript (Goja).
Protocol: Use OpCodes (Numeric Enums) for network messages (Save bandwidth).
Tick Rate: 5 ticks/sec (Optimized for turn-based).
Anti-Cheat: Strict “Fog of War” (Server holds truth, Client sees null).
Lobby Chat: Use socket.joinChat(matchId, ChannelType.Room) for persistent/history-enabled chat before the game starts.
In-Game Chat: Use OpCodes (e.g., OpCode.CHAT_MSG = 5) inside the matchLoop for strictly ephemeral, synchronized game communication (e.g., “Enemy Missing” pings).
6. Performance & Optimization
Binary vs JSON: For high-frequency updates (movement), use Uint8Array buffers instead of JSON strings.
Presences: Don’t iterate state.presences unnecessarily. Cache active player IDs.
Timers: Use state.nextTick counters instead of Date.now() for determinism inside the loop.
7. Anti-Patterns (What to Avoid)
❌ DON’T use npm install for runtime logic. The JS runtime (Goja) is not Node.js. It has no Event Loop, no FS, no Network access (except nk.httpRequest).
❌ DON’T trust message.sender without validation. Ensure the sender actually controls the entity they are trying to move.
You’re implementing a tree-shakable in-game debug menu for Minigolf. The complete spec exists in DEBUG-PANEL.yaml — your job is to code it, not design it.
Phase 5: Polish & test (tooltips, responsive, Playwright, tree-shaking)
📖 COMPLETE SPEC
Source of truth: /home/usr/funday/games/minigolf/docs/DEBUG-PANEL.yaml
Read sections:
architecture → File structure, tech stack
ui_structure → All 5 tabs detailed
implementation_phases → Phased breakdown with subtasks
testing → Playwright specs, manual checklist
success_criteria → How to verify completion
🚨 CRITICAL RULES (NEVER VIOLATE)
Tree-shaking: MUST use import.meta.env.DEV guard + conditional dynamic import
Verify: npm run build → dev menu = 0 bytes in production bundle
Visual verification: ALWAYS use MCP screenshot tools before delivery
Tool: mcp4_browser_take_screenshot or mcp6_puppeteer_screenshot
Navigate to http://dev.funday.gg/play/minigolf?debug=1
Verify: menu renders, tabs visible, no layout issues
Svelte 5 runes: Use $state, $derived, $effect (no legacy $: syntax)
DaisyUI theming: All UI must respect theme (modal, tabs, range, toggle)
Performance: Dev menu UI <5% CPU overhead, state updates throttled to 10Hz
✅ SUCCESS CRITERIA
Phase 1 Complete When:
devState.svelte.ts exists with reactive state
DevMenu.svelte renders with 5 empty tabs
Backtick (`) toggles menu open/close
?debug=1 URL param opens menu
Escape key closes menu
MCP screenshot confirms UI renders correctly
No console errors
Full Project Complete When:
All 5 tabs functional (State, Actions, Tweaks, Debug, Perf)
Live physics tweaking works (no reload needed)
Debug overlays render on canvas
Tree-shaking verified (0KB in npm run build)

🚨 Critical Addition: Visual Verification Rule
Added to both README.md and CHECKLIST.md:
🚨 VISUAL VERIFICATION: ALWAYS use MCP screenshot tools (mcp4_browser_take_screenshot or mcp6_puppeteer_screenshot) to verify visual changes before delivery — never ship broken UI without confirming it works visually
Rationale: Prevents user frustration from broken UI that could have been caught with a simple screenshot verification.
Process:
Navigate to game URL (dev or preview)
Call mcp4_browser_take_screenshot or mcp6_puppeteer_screenshot
Verify: menu renders, tabs visible, no layout issues, theme applied
Only ship after visual confirmation

😇
⛳ Minigolf Champions – Game SSOT
Game ID:minigolf
🧩 Overview
Minigolf Champions is a physics-based sports game with a focus on tight controls, powerups, and mobile-friendly UX.
Players: 1–8
Mode: Skill-based minigolf, future-ready for multiplayer
// Send movesocket.sendMatchState(matchId, 1 /*op*/, JSON.stringify({ move }))socket.onmatchdata = (m) => { if (m.op_code !== 2) return const st = JSON.parse(new TextDecoder().decode(m.data)) // Update local state deterministically from server snapshot}
Reconnect Flow
When ondisconnect fires: mark offline, show Reconnect in Dock, clear ephemeral state.
On reconnect: rejoin the match if matchId is known.
4) Matchmaker (Optional)
Use Nakama’s matchmaker for ranked/queued experiences:
Add to matchmaker: socket.addMatchmaker(minPlayers, maxPlayers, query, stringProperties, numericProperties).
Matchmaker matched: socket.onmatchmakermatched returns token to join.
// Game → Host via Bridge → Host posts to /api/leaderboards/submitbridge.submitScore("minigolf_seasonal", score, { mode: "online" })
Leaderboards can be seasonal; always include game_id, mode, and match_id in metadata for analytics.
7) Server Runtime (TS/Lua/Go)
Add authoritative logic as modules (nakama-modules/ in this repo has examples).
Authoritative flow for minigolf: server validates hits, tracks strokes, resolves ties.
Emit compact snapshots to clients to avoid divergence; clients render and send intents only.
Version 1.0
Initial release (after so many years!) for Pacman emulator.
Version 1.1
Finally got some official (i.e. Zilog) documentation for the Z80, and
the correct instructions for DAA!
Added more comments and explanations to the code.
LDIR, LDDR, CPIR, CPDR, INIR, INDR, OTIR, OTDR are now interruptible
and the cycle count is correct.
Opcodes of type LD r, RLC/RRC/RL/RR/SLA/SRA/SLL/SRL/RES/SET (IX/IY + d)
(undocumented) have been implemented.
Changed HALT management.
Removed support for undocumented flags to make code more clear.
DAA rewritten to avoid lookup table (thanks to S. Donati/S. Young for
documenting that).
Removed readWord() and writeWord() from Z80Environment interface.
Added notification of RETI instruction to Z80Environment interface.
Added run() method to the Z80 class.
Modified some instruction in order to avoid unnecessary calls to
the environment functions (e.g. for conditional branches not taken).

task: explain why panda-publishing is messy + map intent vs reality vs potentialscope: /home/usr/funday/games/panda-publishing ONLYcore_finding: it contains at least two competing architectures + two competing frontends + docs that describe different eras as “current”
🚀 Derived Intent (what panda-publishing wants to be)
🐼 A self-contained game plugin (manifest-driven) using integrationType: svelte-component and entryPoint: src/PandaPublishingGame.svelte.
🎮 Runtime gameplay: Svelte 5 + DaisyUI UI, plus an “office scene” visualization.
🧠 AI story generation:
Path A (current winning path): Nakama RPC module server/panda_rpc.ts calling OpenRouter (ctx.env.OPENROUTER_API_KEY) and persisting to Nakama storage.
Path B (older/alternate path): ai_orchestrator/ FastAPI + DB schema + k8s manifest, called via VITE_PANDA_AI_URL.
💔 Current State Analysis (why it’s a mess)
1) 🧬 Two architectures fighting for “source of truth”
✅ Nakama-first exists and is big + complete: server/panda_rpc.ts exports many rpcPanda* handlers, has economy constants, upgrades catalog, achievements, storage keys, OpenRouter integration, etc.
✅ FastAPI orchestrator also exists and is real: ai_orchestrator/main.py, database/schema.sql, infrastructure/ai-orchestrator-deployment.yaml, requirements.txt.
🔥 Problem: both stacks aim to own:
agent lifecycle
training/modules
story generation pipeline
persistence model
Result: duplicated concepts, drift, and “which one is real?” confusion.
2) 🧟 Two “frontends” (and one is effectively a fossil)
You have:
Plugin runtime UI: src/ (this is what funday-plugin.json points to)
🔁 Duplicate API clients (nakama.ts, panda.ts) in both trees with different auth behavior
🔁 Duplicate UI concept: “pixel office” exists in frontend/src/lib/components/PixelOffice.svelte (DOM/HTML) while plugin has a Canvas office in src/components/PhaserOffice.svelte.
3) 📚 Docs are time-traveling (contradict each other)
You have simultaneously:
docs/ONBOARDING.md saying “Nakama-first, no orchestrator needed” AND claiming “Nakama RPC TODO” (which is false now because server/panda_rpc.ts exists and is huge).
README.md that describes PixiJS/bitECS future plans and also references the frontend/ SvelteKit app.
docs/panda-phaser4.md (your currently open file) describing a Phaser 4 integration that no longer matches reality (your plugin’s office renderer is Canvas; Phaser code still exists but isn’t the live path).
docs/archive/* contains older “game-plugins” path assumptions (/home/usr/funday/game-plugins/...) while current tree is /home/usr/funday/games/....
Net effect: every new dev picks the wrong “truth” depending on which doc they read first.
4) 🧱 Dead / transitional code paths left in-place
Phaser 4 code exists in src/game/* (OfficeScene, AgentSprite, PhaserConfig) while the actual renderer used by src/components/PhaserOffice.svelte is Canvas.
File naming now lies:
PhaserOffice.svelte is not Phaser anymore (Canvas API renderer).
This is classic “migration halfway done” tech debt.
5) 🌍 Environment coupling / hardcoded hosts
At least one client hardcodes https://funday.gg/v2 (seen in frontend/src/lib/api/nakama.ts).
The plugin-side API client is session-token aware (better), but the standalone frontend version isn’t.
This creates “works in prod, breaks in dev” traps.
6) 🧩 Mixed abstractions and inconsistent domain models
Examples:
Training modules:
Orchestrator models use WRITER/EDITOR/... agent types, DB tables, prerequisites.
Nakama RPC path uses writer/editor/proofreader/... roles and stores modules differently.
UI TrainingPanel.svelte currently treats agent.traits as “trained modules” (semantic mismatch).
✨ Latent Potential (what it could be if un-messed)
A clean single-SSOT game plugin where:
UI is Svelte 5 + DaisyUI
All persistence + multiplayer/social is via Nakama (storage + leaderboards)
AI generation is via OpenRouter in Nakama RPCs (already implemented)
Office renderer is one tech (Canvas now, Pixi later), not Phaser+Canvas simultaneously
Optional: the orchestrator becomes a separate experimental serviceonly if it provides something Nakama can’t (long-running jobs, GPU pipelines, etc.)—but right now it mostly duplicates.
🧠 Synthesized Overstanding (root cause in one line)
This folder is messy because it contains multiple abandoned/competing implementation eras (FastAPI-orchestrator era, Phaser era, Nakama-first era, standalone-SvelteKit era) without a single enforced “source of truth” for runtime, build, and docs. 🧨
🛠️ Highest-Leverage Improvements (prioritized)
UID
Improvement
What changes (precise)
Benefit
A
🧭 Declare 1 SSOT architecture
Pick Nakama-first as canonical (it’s already implemented). Mark orchestrator as “experimental/legacy” (or archive it).
Stops split-brain development
B
🧹 Kill the “two frontends” ambiguity
Decide whether frontend/ is kept (as dev sandbox) or removed/archived. Ensure plugin runtime uses only src/.
Removes duplicate API clients + UI duplication
C
🏷️ Rename misleading files
PhaserOffice.svelte → OfficeCanvas.svelte (or similar) OR actually use Phaser again.
Reduces cognitive load + false assumptions
D
🔐 Unify Nakama API client
One nakama.ts implementation (session-token aware, no hardcoded prod host). Remove the divergent copy.
Fixes auth/dev/prod drift
E
🧾 Rewrite docs to match reality
docs/ONBOARDING.md + README.md updated so “how to run / how it works” matches the actual entryPoint + runtime.
New devs stop getting gaslit
F
🗑️ Archive unused eras
Move old Phaser docs + unused orchestrator-related docs into docs/archive/ clearly.
Prevents “wrong doc first” syndrome
✅ Status
Done: Deep scan of /games/panda-publishing structure, entrypoints, runtime paths, docs, and competing architectures.
The Panda Publishing game uses $lib/ imports (e.g., $lib/components/StoryForm.svelte) which resolve to the frontend’ssrc/lib/ folder instead of the game’ssrc/lib/ folder.
Error
Could not load /home/usr/funday/frontend/src/lib/components/StoryForm.svelte
(imported by ../games/panda-publishing/src/PandaPublishingGame.svelte):
ENOENT: no such file or directory
Root Cause
Game components are in /home/usr/funday/games/panda-publishing/src/lib/
Vite’s $lib alias resolves to /home/usr/funday/frontend/src/lib/
No game-specific alias configured in vite.config.ts
Current State
Production: Deployed version works (was built before this issue)
Development: Build fails when trying to rebuild
Solutions
Option A: Symlink (Quick Fix)
# Create symlinks in frontend's lib for panda componentsln -s /home/usr/funday/games/panda-publishing/src/lib/components/StoryForm.svelte \ /home/usr/funday/frontend/src/lib/components/StoryForm.svelte# ... repeat for all game components
This game uses integrationType: "iframe-themeable" which loads the pre-built
frontend/build/ directory directly. Any rebuild without proper setup will break the game.
For Development
If you need to modify panda-publishing:
Set up all required environment variables
Configure Nakama RPC endpoints
Test locally with npm run dev first
Only build after confirming dev works

🔧 Pipes Game — Fix Log
✅ FIXED: Missing Store Methods (2026-04-18)
Issue
Runtime crashes on puzzle solve, tab switch, and new puzzle — caused by missing method implementations.
Root Causes
progress.svelte.ts — recordCompletion() and getMasteryProgress() called by PuzzleInstanceWrapper.svelte (lines 348, 166) but never implemented on PuzzleProgress class.
stores/index.js — pause(), unpause(), skip() called by PuzzleInstanceWrapper.svelte and daily/+page.svelte but never implemented on solves store.
Fixes Applied
Added pause(puzzleId) — records pausedAt timestamp for visibility-change pausing
Added unpause(puzzleId) — adjusts startedAt to compensate for paused duration
Added skip() — clears active solve without recording (for puzzle abandonment)
Added recordCompletion(kind, size, completionId) — marks completed + checks for size/pattern unlocks
Added getMasteryProgress(kind) — returns {completed, total} for size tier progression
Puzzle grid did not render — SVG showed negative width/viewBox errors.
Root Cause
PuzzleKindWrapper.svelte had solves assigned in onMount without $state(), so template never re-rendered.
Fix
Converted solves to $state(null) — already applied.
⚠️ Known Issues (non-critical)
Pre-existing Test Failures
11 streak-calculation tests in stats.test.js fail due to hardcoded dates (2022-2025) compared against new Date() (2026). These need date mocking.
Svelte 5 Warnings
Puzzle.svelte has state_referenced_locally warnings — props captured at initial value instead of reactively. Non-blocking since grid/tiles don’t change after mount, but should be cleaned up.
API Endpoints
/api/games/hexapipes/puzzle/get|save|submit return 404 in dev (no backend). Handled gracefully with try/catch.

First Fix Priority
Implement FundayBridge SDK integration — This unblocks all platform features (matchmaking, theming, analytics, score submission).
Rationale: Current handler has logic but never executes game state machine.
-- pong_party_match.lua — Add game executionfunction match_loop(context, dispatcher, tick, state, messages) -- Process inputs (existing) for _, msg in ipairs(messages) do if msg.op_code == OP.PLAYER_INPUT then local data = nk.json_decode(msg.data) state.inputs[msg.sender.user_id] = data.direction end end -- === ADD: Phase machine === if state.phase == 'waiting' then if table_length(state.players) >= 2 then state.phase = 'countdown' state.countdown = 3 * TICK_RATE -- 3 seconds end elseif state.phase == 'countdown' then state.countdown = state.countdown - 1 if state.countdown <= 0 then state.phase = 'playing' reset_ball(state, 1) -- Serve to player 1 end elseif state.phase == 'playing' then update_paddles(state) -- Existing update_ball(state) -- Existing check_scoring(state, dispatcher) -- ADD: Trigger on score elseif state.phase == 'scored' then state.countdown = state.countdown - 1 if state.countdown <= 0 then if check_win_condition(state) then state.phase = 'finished' broadcast_game_over(state, dispatcher) else state.phase = 'playing' reset_ball(state, state.last_scorer == 1 and 2 or 1) end end end -- Broadcast state (existing) broadcast_state(state, dispatcher, tick) return stateend
Solution D: Responsive Canvas (High)
Rationale: Current fixed 1600x900 doesn’t adapt to mobile/tablet.
// Replace fixed dimensions with responsivelet canvasContainer: HTMLDivElementlet dpr = $state(window.devicePixelRatio || 1)$effect(() => { const resize = () => { if (!canvasContainer || !canvas) return const rect = canvasContainer.getBoundingClientRect() const aspect = ARENA_W / ARENA_H let w = rect.width let h = w / aspect if (h > rect.height) { h = rect.height w = h * aspect } canvas.width = w * dpr canvas.height = h * dpr canvas.style.width = `${w}px` canvas.style.height = `${h}px` ctx?.scale(dpr, dpr) } resize() window.addEventListener("resize", resize) return () => window.removeEventListener("resize", resize)})
Solution E: Input Event-Based (High)
Rationale: rAF loop wastes battery; event-based is standard.

How It Works
// src/lib/funday.tsimport { browser } from "$app/environment"import { appState } from "$stores/app"// 1. Detect embed modeexport function isEmbed(): boolean { const params = new URLSearchParams(window.location.search) return params.get("embed") === "1"}// 2. Initialize bridgeexport async function initFundayBridge(): Promise<void> { if (!browser || !isEmbed()) return const FundayBridge = window.FundayBridge // Injected by host bridge = new FundayBridge({ onSession: ({ user }) => { // Inject player name from Funday identity appState.options.player.name.set(user.displayName || user.username) }, }) bridge.init()}// 3. Signal ready when game can renderexport function signalReady(): void { bridge?.ready()}
Bridge Lifecycle
1. Game loads in iframe with ?embed=1
2. StartPrompt.svelte detects embed mode
3. initFundayBridge() called
4. Host sends funday:handshake → game ACKs
5. Host sends funday:session-inject → game sets player name
6. After 500ms delay, game auto-starts
7. signalReady() called → host shows game as ready
🎯 Asset Path Strategy
Problem
Root-absolute paths like /sfx/click.mp3 resolve to https://funday.gg/sfx/click.mp3 (404) instead of https://funday.gg/games/assets/racemania/sfx/click.mp3.
Solution
// src/lib/asset.tsimport { base } from "$app/paths"export function asset(path: string): string { const cleanPath = path.replace(/^\/+/, "") return `${base}/${cleanPath}`}// Usageimport { asset } from "$lib/asset"const audioUrl = asset("/sfx/button-click.mp3")// → "/games/assets/racemania/sfx/button-click.mp3"
For the next agent: The game is fully functional. Focus testing on the live site at https://funday.gg/play/racemania. If Svelte 5 migration is needed, start by upgrading Threlte to v8 first.

🚀 Briefing (Intent/Top Flaws/First Fix)
Intent:
Rift Coalition is designed as a co-op PvE sector-run game (1-4 players) natively mounted within the Funday platform. It uses the svelte-component integration type with a fast and thin nakama-ts generic match wrapper. The clear goal is to deliver seamless multiplayer “hold the line” strategy mechanics.
Top Flaws (The Void):
Currently, the codebase is a pristine, empty shell. It exists merely as a UI mock-up for lobbying and practice drills context with zero actual gameplay logic, rendering, or game-state syncing mechanisms.
First Fix:
Draft the core unified Game State (Svelte 5 runes $state) and bind it to the Nakama match matchLoop via custom opcodes, creating a tight, reactive data flow between client and server before integrating a visual engine.
Gems:
The platform generic lobby connection is already perfectly scaffolded in rift_coalition_match.ts. You don’t need to rebuild networking room handling.
2025+ Upgrades:
Use Svelte 5 Runes natively for syncing Nakama network packets directly into UI signals. By parsing binary/JSON payloads from the platformBus straight into a $state store, we bypass prop-drilling entirely.
Render loop via WebGPU or lightweight canvas using reactive boundaries.

Phase 1: Architecture & Opcodes
Define shared/opcodes.ts for strictly typed Network messages.
Implement Svelte $state stores for purely native reactive bindings.
Phase 2: Authoritative Logic
Expand matchLoop inside server/rift_coalition_match.ts to manage Wave Ticks, Spawn Logic, and Health.
Track presences vs active game entities.
Phase 3: Visuals & UI
Map out the “Sector” using a CSS Grid or <canvas>.
Wire up the “Practice/Drill” mode to test game loop fully locally without Nakama.
✅ Rec Path (Synthesis/First Steps)
The project is a completely clean slate wrapped in pristine Funday platform scaffolding.
Next Step & Recommendation:
Do not touch the UI until the core engine loop is built! Start by defining the Network Opcodes and wiring a basic “Tick” loop in the Svelte client using Svelte 5 runes. Create the state definitions that the server and client will share, then flesh out matchLoop to increment those states.

Use two browsers (or guest + account) on the same environment (e.g. funday.gg/play/scribblaz or local frontend dev server).
Host: open /play/scribblaz → dock Lobby → create match → ready → start when ≥2 players ready.
Guest: open invite or lobby list → join same match → ready.
Draw round: drawer receives word choices; guessers see canvas via DRAW_RELAY and can SEND_GUESS.
Exit: verify round_end → next word_pick or game_end; no console spam.

🔮 Prevention Strategies
1. Documentation Staleness Guard 📖
Add a date field to SCRIBBLAZ.md header → compare during reviews
After changing any constant in gameState.ts, grep for its mention in .md files
Consider a CI check: grep -c 'MATCH_IDLE_GRACE_S.*60' docs/ should return 0
2. Dead Code Prevention 🗑️
Enable noUnusedLocals in tsconfig.json for the game directory
PlayerList.svelte should either be wired or explicitly documented as “planned”
Use // TODO: tags for planned-but-unused code to distinguish from forgotten
3. Test Coupling 🧪
canvasEngine.test.ts duplicates the draw-stack state machine (F9)
Extract the pure computeDrawStack() function from canvasEngine.ts and import it
This prevents test/production code divergence
4. Serialization Safety 💾
FillEvent._snapshot (ImageData) is non-serializable (F12)
Add a stripTransients() helper before JSON.stringify() in persistence code
Or use JSON.stringify(events, (k,v) => k.startsWith('_') ? undefined : v)

ScribblaZ is in excellent shape. The codebase is clean, well-documented, well-structured, and production-ready. The only work remaining is feature expansion (PlayerList wiring, tests, trainer mode, gallery) — no architectural or cleanliness debt.
Production verification (2026-03-24): Fetched funday.gg/play/scribblaz — standard Funday play shell (nav, guest chip, dock Feedback / Fullscreen / Exit, Game Feedback drawer). Game UI is client-hydrated; static fetch does not execute canvas/Nakama.

CAUTION
F1-sub: Auto-picked word = gibberish hash .js L1925: state.currentWord = state.wordOptions[...]
This picks a hash like "k2x9f3m1" instead of the actual word. .ts L1072 correctly resolves: state.wordOptionsHashMap[randomHash] Impact: If drawer doesn’t pick within 10s, players see/guess a random hash.
Fix: Production SSOT — funday/nakama-modules bundles match_handler.ts via esbuild (@games/scribblaz/server/match_handler → index.js). Run npm run build in nakama-modules for deploy. Done (2026-03-24): legacy server/match_handler.jsdeleted; server/.gitignore ignores match_handler.js if tooling regenerates it.
Eraser still passes #ffffff as the stroke color token so the engine can detect eraser mode
Status:Mitigated — drawStroke uses globalCompositeOperation = 'destination-out' when color === '#ffffff'. 2026-03-24:drawShape applies the same rule so line/box/circle eraser cuts alpha instead of painting white.
F4 · Client Timer Has No Interpolation — 5-Second Jumps ⏱️
Files
ScribblaZController.svelte.ts · HintBar.svelte
Severity
🔴 Major UX — timer display jumps in 5s increments
What
Server sends TIMER_SYNC every 5s; client must interpolate between ticks
Status:Mitigated — controller runs a 50ms setInterval via _ensureTimerRunning() / syncTimerToPhase() so msRemaining decrements between TIMER_SYNC messages, and the interval stops when leaving timed phases (waiting, game_end, etc.) so the clock does not run in the lobby.
🟡 IMPORTANT (8)
F5 · PlayerList.svelte — Component Exists, Never Rendered 👻
File
PlayerList.svelte
What
81-line component with sorted player list, drawer indicator, score display. Imported nowhere.
CHECKLIST
Item 4.7 confirms: “Wire up PlayerList.svelte component (exists but not imported/rendered)”
Fix: Import in ScribblaZGame.svelte and render in the game view (left sidebar or overlay).
F6 · displayPalette Derived — Dead Code 🧟
File
ScribblaZController.svelte.ts:78-81
What
Computes reordered palette based on lastUsedColor, but no component reads ctrl.displayPalette
Fix: Either render the swap pair + history, or remove the unused props to avoid confusion.
F8 · canvasEvents Grows Unbounded on Server 📈
File
match_handler.ts — state.strokes
What
Every draw operation (stroke, undo, redo, clear, fill, shape) appends to state.strokes. No pruning.
In a 3-round, 80s/round match with an active drawer (10 ops/tick × 5 ticks/s × 80s = 4,000 events/round × 3 = 12,000 events). Every new joiner receives ALL of them via GAME_STATE.
Impact: Inflated join payloads, increased server memory, slow reconnections.
Fix: After a clear event, prune all preceding events (they’re invisible). After round_end, reset state.strokes = [].
Status (2026-03-24):endRound and endGame in match_handler.ts now set state.strokes = [] after broadcasting (join payloads shrink during round_end / game_end). startWordPick already cleared strokes at round boundaries. Pruning within a draw phase on DRAW_CLEAR without breaking undo is still optional follow-up.
F9 · canvasEngine.test.ts Tests Extracted Logic, Not Actual Code 🧪
File
canvasEngine.test.ts
What
The test defines its own computeDrawStack() function that mirrors the state machine. It does NOT import from canvasEngine.ts.
If the real replayStrokes() implementation changes, these tests continue to pass (false positive). The test and production code can diverge silently.
Fix: Extract the state machine as a pure function from canvasEngine.ts and import it in the test file.
F10 · Keyboard Redo May Double-Fire 🔁
File
ScribblaZGame.svelte:303
What
Ctrl+Shift+Z calls BOTH canvasRef?.performRedo() AND handleRedo()
If performRedo() internally fires the onRedo callback (which triggers handleRedo → send(OP.DRAW_REDO)), then handleRedo() on line 303 sends it a second time.
Result: Two DRAW_REDO ops sent to server → server processes both → double-redo.
Fix: Use the same pattern as undo — call canvasRef?.performRedo() only, and let DrawCanvas emit via its callback. Remove the explicit handleRedo() call.
F11 · Canvas onwheel May Be Passive — preventDefault() Ignored 🖱️
File
ScribblaZGame.svelte ($effect + canvas shell)
What
handleCanvasWheel calls preventDefault() for brush resize
Status (2026-03-24):Fixed — removed Svelte onwheel binding; $effect attaches addEventListener('wheel', …, { passive: false }) on layoutManager.canvasShellEl while in non-waiting phases so scroll-zoom does not steal the gesture.
FillEvent has _snapshot?: ImageData for cached replay optimization
If CanvasEvent[] is ever JSON.stringify()’d (e.g. in drawingPersistence.ts for free-draw save), ImageData is silently dropped or throws. The _snapshot data is unbounded (800×600×4 = 1.9MB per fill).
Impact: Persistence corruption or payload bloat.
Fix: Strip _snapshot* fields before serialization. Add a toSerializable() helper.
If the plugin isn’t installed, these classes are no-ops → overlays appear without entrance animation.
Fix: Verify tailwindcss-animate is in dependencies, OR replace with Svelte transition: directives (already used elsewhere).
F16 · Opcode Number Gaps / Naming Oddity 📡
File
gameState.ts:6-35
What
Opcodes 1-9 are client→server, 10-23 mixed. DRAW_REDO = 22 is far from DRAW_UNDO = 5
Not a bug, but poor locality makes maintenance error-prone. Group by function:
Draw: 1-5 + 22 (redo stranded at 22)
Game flow: 6-9, 10-21
Kick: 23
F17 · No Server Max-Points or Max-Width Enforcement 🛡️
File
match_handler.ts — handleDraw()
What
SCRIBBLAZ.md documents MAX_STROKE_POINTS = 500 and MAX_BRUSH_WIDTH = 50, but the server code has NO such limits
A malicious client could send a stroke with 100,000 points or width 9999. Per-tick rate limit (10 ops/tick) helps, but doesn’t cap payload size per op.
Fix: Add points = points.slice(0, 500) and width = Math.min(50, Math.max(1, width)) in handleDraw.

🐢 Infinite Turtles — Onboarding Prompt for Next Agent (OUT)
🧭 TL;DR
Goal: Ship a platform-ready 3D card-battler embedded at /play/infinite-turtles with guest-first UX, Bridge v1 HUD/Dock, and server-owned deck integrity via Nakama.
State: Prototype strong; platform docs in place; fungame validated; platform nested dev plugins supported; service needs restart to load latest build; turtles still needs BridgeService + deck RPCs + locks + joinAttempt.
1.1 Task: Run npm run preview in games/turtle-cards and open the preview URL; verify no red console errors during a full flow (Main Menu → Deckbuilder → Save/Primary/Delete → Back to menu).
1.2 Task: If preview looks clean, mark checklist item 0.2.2 as done in games/turtle-cards/docs/development/CHECKLIST.md.
2. Section: Embed & Host Integration
2.1 Task: Confirm /play/turtle-cards host route always uses ?embed=1 when embedding the plugin; document the contract in the relevant frontend docs/config.
2.2 Task: On mobile (Chrome devtools + real device), verify viewport sizing: game content uses 100svh/dvh minus Funday HUD/Dock, and safe-area insets don’t hide critical UI (1.2.1, 1.2.2).
2.3 Task: Hit /games/assets/turtle-cards and /play/turtle-cards on dev/staging/prod, ensuring HTTP 200 and no red console errors; then update 8.2.* checklist items.
3. Section: Bridge Analytics Completion
3.1 Task: Extend Turtle Cards client to emit deck_lock analytics in Deckbuilder after a successful lockDeckForMatch call (to be added in the next section).
3.2 Task: Once matchmaking stub exists, emit match_queue, match_join, match_result at the appropriate points in the flow via trackEvent in bridgeService.ts or scene logic.
3.3 Task: Verify all deck_* and match_* events are visible in Funday analytics dashboards; then mark 2.3.2 as done.
4. Section: Deck Lock & Queue Stub
4.1 Task: Add a “Lock deck for match” or “Play online” button (either in MainMenu.svelte or Deckbuilder.svelte) that uses lockDeckForMatch from src/lib/api/gameApi.ts on the current/primary deck.
4.2 Task: Surface lock state in the UI (e.g., lightweight “Deck locked (checksum: …)” banner, optional remaining time if you compute TTL).
4.3 Task: After lock success, emit deck_lock analytics with { deckId, checksum, size, format } from the Deckbuilder side.
5. Section: Matchmaking & Match Validation
5.1 Task: Add a simple “Queue for match” client flow that, given a locked deck, sends { deckHash, format, region } into matchmaking properties using existing Funday matchmaker helpers.
5.2 Task: On match found/joined, wire the response into Turtle Cards scene transitions (reusing existing combat scene as the match view).
5.3 Task: Implement or extend a matchJoinAttempt hook in nakama-modules (TS or Lua) for Turtle Cards matches to validate turtle_deck_lock/current (ownerId, deckId, checksum, TTL).
5.4 Task: In matchJoinAttempt, reject invalid/expired locks with friendly error codes/messages compatible with the client UX; pin deck snapshot into match state; mark 5.3.* in checklist when done.
6. Section: Deckbuilder A11y & Performance
6.1 Task: Address Svelte a11y warnings in Deckbuilder.svelte (e.g. switch interactive div rows to <button> or add proper keyboard handlers) and explicitly set ARIA roles/labels for Deck/Library lists (finishing 4.2.3).
6.2 Task: If the card catalog grows, introduce lightweight virtualization or chunked rendering for the library list and memoize derived filters where beneficial (4.3.1, 4.3.2).
6.3 Task: Re-run npm run build and ensure no new warnings or errors; keep the Deckbuilder overlay snappy on mid‑range devices.
7. Section: Security & CSP Boundaries
7.1 Task: Audit Turtle Cards plugin code for any direct Nakama storage writes or unauthorized writes; confirm all deck data mutations happen only through server RPCs (6.1.1).
7.2 Task: Review CSP and origin handling for Turtle Cards in the host frontend (nginx/SvelteKit side) to ensure iframe/embed usage does not weaken platform policies (6.2.*) and document any constraints.
8. Section: Build, Publish, Smoke Tests
8.1 Task: Formalize the “build and publish” step for Turtle Cards: document and, if needed, script copying games/turtle-cards/build into the game-plugin location used by /games/assets/turtle-cards, then mark 8.1.2.
8.2 Task: After matchmaking is in place, run a two‑browser smoke test (desktop + mobile) queuing into the same match, playing a few turns; watch for console errors and perf; then tick 8.3.*.
9. Section: Docs & Cross-links
9.1 Task: Update Turtle Cards docs (docs/turtle-funday-deckbuilder.md, docs/turtle-revamp*.md) to reflect the actual Nakama RPC contracts, GameAPI wrapper, and Deckbuilder UX (including lock/match once done).
9.2 Task: Ensure any global architecture docs (ARCH-UP, GAME_AUDIT_LOG, integration YAMLs) contain an accurate Turtle Cards row with integration details (entry route, integrationType, deck RPCs, lock/match behavior).
Next-Agent Onboarding Prompt
You are the next agent continuing the Turtle Cards vertical slice for the Funday platform.
Context you MUST know
Project: Funday gaming platform, private repo, no public deploys.
Game: Turtle Cards (rewrite of “Infinite Turtles”) living under games/turtle-cards/.
Format + banlist hook (TURTLE_DECK_FORMATS) and normalized checksum = 'v1:' + sorted(cardIds).join(',').
Mutating RPCs are rate-limited and log structured success events with correlation IDs.
GameAPI wrapper in games/turtle-cards/src/lib/api/gameApi.ts:
Wraps all turtle_deck_* RPCs and uses funday-nakama.js + bridge/FundayAuth session.
All Deckbuilder network calls go through this module.
Bridge & HUD/Dock in src/lib/bridgeService.ts:
Dynamically imports FundayBridge from /games/assets/_sdk/funday-bridge.js.
Handles theme/locale/session injections.
Emits funday:nav:set and funday:dock:set based on GameState and menuState.
For menuState === 'deckbuilder', it configures Dock actions: deck_save, deck_primary, deck_reset, back_to_menu, and dispatches them into the game via a windowCustomEvent('turtle-deckbuilder-action').
Deckbuilder scene:
GameState.menuState has 'deckbuilder'.
MainMenu.svelte includes a “deckbuilder” button that switches to that scene.
App.svelte renders <Deckbuilder /> overlay when menuState === 'deckbuilder'.
Deckbuilder.svelte:
Uses Svelte 5 runes extensively.
Uses data.cardTypes for card metadata.
Allows adding/removing cards, with filters and search.
Enforces 30–60 cards and ≤4 copies per id.
Emits deck_save, deck_primary, deck_delete analytics on success.
Listens for bridge actions (deck_save, deck_primary, deck_reset) via window events.
npm run build in games/turtle-cards passes and writes to build/.
What you should FOCUS on next
Use the checklist above as your driver. In order of highest leverage and dependency:
Run preview & sanity-check Deckbuilder + HUD/Dock (Task 1.1):
You should not change code for this; just verify behavior and then update the checklist if clean.
Add server hooks to validate lock and pin deck snapshot.
Polish embed/host integration and analytics dashboard verification (Tasks 2., 8.2.).
Finish a11y/perf and docs alignment (Tasks 4.2.3, 4.3., 6–7, 9.).
How to operate
Use games/turtle-cards/docs/development/CHECKLIST.md as the live driver. It’s been pruned to only unfinished tasks; do not reintroduce done items.
Keep changes contained to:
games/turtle-cards/src/lib/** for plugin UI/logic.
nakama-modules/index.ts for server behavior.
After each logical piece:
Ensure npm run build in games/turtle-cards still passes.
Only then tick the corresponding checklist items.
If you follow the Task List in order, you will advance the Turtle Cards vertical slice from “deckbuilder-ready” to a fully locked, match-validated, embed-stable production slice.

Task List (/cl)
1. Bridge & App Shell
1.1 Task: Implement BridgeService (ack, injections) and wire to scene router
1.2 Task: Emit funday:nav:set per scene with correct actions; listen for funday:action

1.4 Task: Send funday:analytics-event on deck_save/delete/primary/lock and match_queue/join
Persist Turtle Cards run state (phase, lives, deck, cards in play/hand/discard, RNG seed) on Nakama so that when a player switches games or closes the tab, they can resume exactly where they left off the next time they open /play/turtle-cards.
Server‑owned writes via Nakama Storage + RPCs.
Safe for guest‑first accounts (Nakama session still has a user ID).
Works across devices and multiple concurrent tabs.
🧱 Nakama Data Model – turtle_progress
Collection:turtle_progress Key:run_v1 (one active run per user per mode; expand with more keys later) Permissions:
permission_read = 1 (owner only)
permission_write = 0 (only runtime/RPC may write)
Value shape (conceptual JSON):
{ "version": 1, "mode": "standard", // future‑proofing for alternate modes "phase": 3, // current level / encounter index "lives": 2, "hp": 5, // optional, if not implied by lives "deckId": "deck_primary_1", // links to validated deck in turtle_decks "board": [ // enemies + player card snapshot { "slot": 0, "typeId": 1, "health": 3 }, { "slot": 1, "typeId": 5, "health": 2 } ], "hand": [12, 7, 9, 4], // card type IDs in hand "discard": [11, 3], "seed": "rng-seed-1234", // to reproduce future random draws "updatedAt": 1732500000000, // server timestamp in ms "isComplete": false // true when run is finished / abandoned}
Notes / best practices:
Keep the snapshot minimal but sufficient to reconstruct Turtle Cards internal gameState/cardState.
Include a version field and keep old readers tolerant of unknown fields.
Use seed + deck composition to re‑derive non‑critical details instead of serializing the entire Threlte scene graph.
🔌 RPC Contracts (Nakama Runtime)
All access to turtle_progress goes through server‑side RPCs, never direct client storage writes.
If not found or isComplete == true or updatedAt older than TTL (e.g. 7 days), returns { hasRun: false }.
Otherwise returns { hasRun: true, snapshot }.
turtle_run_save
Type: RPC (input { snapshot }).
Auth: Requires a valid session.
Responsibilities:
Validate ownership and integrity:
phase within allowed range.
lives/hp within configured bounds.
deckId belongs to the user via turtle_deck_get / turtle_deck_list.
Sum of board + hand + discard does not exceed valid deck size.
Optionally validate a checksum driven from (phase, lives, deckId, seed, etc.) if you want to detect tampering from untrusted clients.
Build a sanitized snapshot:
Force server‑side updatedAt = now.
Force version to current schema version.
Upsert into Nakama Storage:
collection = "turtle_progress".
key = "run_v1".
permission_read = 1, permission_write = 0.
turtle_run_clear
Type: RPC (input optional {"mode": "standard"}).
Behavior:
When a run ends (victory/defeat) or user hits “New Run”, either:
Delete the storage object, or
Mark isComplete = true and write once more (preserves historic data for analytics).
🎮 Turtle Cards Client Flow (Svelte/Threlte)
The game client should treat Nakama as the single source of truth for resume state, with a thin local fallback if the network is temporarily unavailable.
1. Boot / Resume Flow
On game mount (+page.svelteonMount → ensureBridge() → session injected):
Ensure you have a connected Nakama client/session (re‑use what gameApi.ts already uses for deck RPCs).
Call turtle_run_get once:
If hasRun: false: start a fresh run (startGame(phase = 1) etc.).
If hasRun: true: show a lightweight resume UI:
”▶ Continue last run” vs ”⟳ Start over”.
On resume:
Map snapshot → internal gameState/cardState:
Set phase, lives, and any other scalar fields.
Rebuild board/hand/discard from arrays.
Re‑seed your RNG from snapshot.seed.
2. Autosave Triggers
Define a small helper inside Turtle Cards client, e.g. queueAutosaveFromGameState():
Called after all state‑changing actions, for example:
After endTurn() resolves.
After a new phase starts or ends.
After deck composition changes (card added/removed from deck).
When the game transitions to/from pause/menus.
Responsibilities:
Build a minimal snapshot from gameState + cardState.
Fire turtle_run_save(snapshot)debounced (e.g. max once every 2–3 seconds).
If offline or RPC fails transiently:
Optionally store the last snapshot in localStorage and retry in the background when connectivity returns.
3. Page Exit / Game Switch
Because autosave runs after every major action, a sudden tab close or game switch is usually already covered.
Optionally attach a beforeunload / pagehide listener that performs one last best‑effort save:
Use navigator.sendBeacon or a fire‑and‑forget RPC call.
Do not block unload; just try and ignore failures.
4. Run Completion
When the run ends:
Call turtle_run_clear().
Optionally write a short summary object to another collection (turtle_runs_history) for analytics.
🧠 Best Practices & Gotchas
Server‑owned progress: Always write progress from inside runtime RPCs; never allow the client to call storageWrite directly.
Versioning:
Include snapshot.version and keep old versions readable.
If shape changes, use a migration function in turtle_run_get to normalize to latest version before returning.
TTL / pruning:
If a snapshot is older than your chosen TTL (e.g. 7–30 days), treat it as non‑resumable and either delete or archive it.
Anti‑cheat (light):
Validate phase + lives are consistent with maximum possible progress given deck and previous saves.
Use server‑side random seeds for sensitive game modes so the client cannot forge arbitrary favorable positions.
Cross‑device:
Because the key is per‑user, the same snapshot appears on any device, so resuming works across browser sessions.
