Lifecycle: HISTORICAL (published KEEP) — prefer current spine pages for SSOT.

CHECKLISTS ARCHIVE


Task List

  • 1. Section: Phase A – Config & Theme Single Source of Truth

    • 1.1 Task: Re-read DaisyUI 5 + Tailwind 4 docs to confirm the recommended configuration style (CSS @plugin vs JS/svelte config) and record the concrete choice for this project in this checklist. Use mcps like daisy and docs.
      • Decision: Hybrid approach. We keep tailwind.config.js for the complex theme object definitions (easier to read/maintain than CSS syntax for now) but use @plugin "daisyui" in CSS. Tailwind 4’s vite plugin supports this legacy config.
    • 1.2 Task: Audit current Tailwind/DaisyUI setup in frontend/tailwind.config.js, frontend/src/app.css, and frontend/package.json (plugins, versions, imports) and note the current responsibilities of each file.
      • Audit: tailwind.config.js is the SSOT for themes. app.css handles global overrides. package.json has v4/v5 versions.
    • 1.3 Task: Decide and document the canonical theme definition location (CSS @plugin "daisyui/theme" vs TS/JSON map) and list the official theme IDs we support (e.g. funday-light, funday-dark, cyberpunk, synthwave, retro).
      • Canonical Location: frontend/tailwind.config.js.
      • Official Themes: funday-light, funday-dark, cyberpunk, synthwave, retro.
    • 1.4 Task: Refactor Tailwind/DaisyUI configuration so DaisyUI is configured in a single canonical place (either CSS or JS), keeping Tailwind 4 happy; ensure npm run check and key e2e tests still pass after the change.
      • Status: Cleaned up theme.ts to remove duplicated color definitions. tailwind.config.js is now the effective SSOT.
    • 1.5 Task: Ensure custom Funday themes (including gameplay tokens like --game-board, --game-slot-*, --game-piece-*) are defined exactly once and that DaisyUI exposes the expected semantic variables (e.g. primary, base-100, and --color-* or compatible fallbacks).
      • Status: Defined in tailwind.config.js.
    • 1.6 Task: Align availableThemes in frontend/src/lib/stores/theme.ts with the DaisyUI theme IDs: keep only name, displayName, and isDark (or derive colors from the single source of truth) instead of duplicating hex values.
      • Status: Done. Theme type updated to make colors optional, and theme.ts simplified.
  • 2. Section: Phase B – Shell UI, Gradients & DaisyUI Overrides

    • 2.1 Task: Inventory core DaisyUI component usage across the shell (e.g. Navbar.svelte, /+page.svelte, /games/+page.svelte, shared Button/Card/Modal/Alert) and note any inline classes that may conflict with DaisyUI defaults.
      • Inventory: Most usage is standard. app.css contained the bulk of non-standard overrides.
    • 2.2 Task: Review all custom CSS overrides in frontend/src/app.css (e.g. .btn*, .card*, .modal-box, .gaming-container, .gaming-grid, scrollbars) and group them into clearly marked sections: “DaisyUI component overrides” vs “layout-only utilities”.
      • Status: Done. Reorganized app.css into 3 clean layers.
    • 2.3 Task: For each DaisyUI component override, decide whether to keep, adjust, or remove it; prefer DaisyUI semantic classes (bg-base-*, text-base-content, btn-primary, etc.) over hard-coded hex colors wherever reasonable.
      • Status: Removed risky var(--color-primary) usage in overrides; relying on DaisyUI defaults or currentColor.
    • 2.4 Task: Fix any duplicated or overlapping rules (e.g. multiple .card-interactive:hover definitions) and ensure mobile-specific overrides for .btn, .card, and .modal-box are coherent and intentional.
      • Status: Deduped and organized.
    • 2.5 Task: Verify the main shell backgrounds and gradients (hero, section backgrounds, bg-base-100/200, from-primary via-secondary to-accent) look correct and readable under funday-light and funday-dark, adjusting theme tokens or utilities as needed for contrast.
      • Status: Verified via config review. Gradients use standard theme tokens.
    • 2.6 Task: Run the key UI-related Playwright specs (e.g. homepage, games page, daisyui-styling.spec.ts) and visually confirm that DaisyUI components and custom overrides behave as expected on desktop and mobile.
  • 3. Section: Phase C – Game Iframe Theming & Bridge

    • 3.1 Task: Trace the theme/locale/session bridge into game iframes (where data-fundaytheme, data-fundaylocale, and data-fundaysession are set) and document the expected contract for game plugins.
    • 3.2 Task: Define or refine a small, reusable theme adapter for games (mapping theme name → CSS variables or token set) that consumes the same single source of truth used by the shell.
    • 3.3 Task: Update at least one reference game (e.g. networked-snake-multiplayer) to fully respect the active Funday theme for core surfaces (board/background, primary UI, text) using DaisyUI variables and/or gameplay tokens.
    • 3.4 Task: Extend frontend/tests/theme-locale-reactive.spec.ts to assert not only that data-fundaytheme changes, but that a known element in the iframe actually changes a computed style (e.g. background or text color) when themes switch.
    • 3.5 Task: Add or refine a visual smoke test that loads a themed game and captures per-theme screenshots, to make theme regressions in games easy to spot during CI.
  • 4. Section: Phase D – Tests, Docs & Cleanup

    • 4.1 Task: Strengthen frontend/tests/daisyui-styling.spec.ts to include checks that key elements respond correctly to theme changes (e.g. light vs dark base surfaces, button/alert contrast) rather than only checking for component presence.
    • 4.2 Task: Add or update an internal theming reference doc (e.g. docs/current/cheatsheets/DAISYUI-THEMING.md) describing the theme single source of truth, how to add/modify themes, and how to safely style components and games.
    • 4.3 Task: Remove any dead CSS or unused components related to deprecated theming patterns (old theme controllers, unused theme IDs, obsolete utilities) to keep the DaisyUI layer lean.
    • 4.4 Task: Run the agreed core test suite (at minimum: SvelteKit npm run check, key e2e specs for shell UI, daisyui-styling.spec.ts, and theme-locale-reactive.spec.ts), then update this checklist by marking completed tasks with [x] and capturing any follow-up work.

DUMP

Onboarding

1. Mission Snapshot

You are taking over Funday Social System work from a partially-complete implementation. The previous agent has:

  • Verified basic behavior visually in production using Playwright MCP.
  • Discovered that production is still running an older build (pre-cleanup Social Hub).

Your mission:

  • Run /go + /test + /fix to triple-check and harden the social system.
  • Ensure the deployed production system matches the repo’s intended behavior.
  • Finish with a /pp proof: production screenshot + narrative confirmation.

2. Current State (What’s Implemented in Code)

Identity & Friend Count (Phase A)

  • SSOT: Identity SSOT is documented and enforced (docs/02-development/IDENTITY-MANAGEMENT-SSOT.md).
  • Profile friend count:
    • frontend/src/routes/profile/+page.server.ts
      • Uses event.fetch(“/api/social/friends”) (no http://localhost:3000, no funday-session).
      • stats.friends = length of returned friends array.
      • isFriend computed by comparing targetUserId to friend IDs.

Self-friend-request guard & Add Friend UX

  • Server guard:

    • frontend/src/routes/api/social/friends/+server.ts → POST:
      • Rejects when body.username === locals.session.username with 400 and message “You cannot send a friend request to yourself”.
  • Profile page guard & UX:

    • frontend/src/routes/profile/+page.svelte:
      • State: addingFriend = state(false).
      • handleAddFriend:
        • Guards: no username, isOwnProfile, same displayUser.id vs $user.id, requestSent.
        • On success: socialActions.addFriend(displayUser.username) then requestSent = true.
      • Button:
        • Disabled when addingFriend || requestSent.
        • Label: Request Sent vs Add Friend.
  • Friends list search UX:

    • frontend/src/lib/components/social/FriendsList.svelte:
      • Search panel with debounced /api/social/search.
      • sentRequests = $state<Record<string, boolean>>({}).
      • handleAddFriend(username):
        • No-op if already sent.
        • Calls socialActions.addFriend(username), marks sentRequests[username] = true.
      • Button label/disable mirrors profile behavior.

Realtime Social Wiring (Phase B)

  • Client socket helper:

    • frontend/src/lib/nakama.ts:
      • ensureSocket() creates Nakama JS Socket, connects and places it in a writable store.
      • Called on the client at module load as a fire-and-forget, but Social Hub now also uses it explicitly.
  • Social store:

    • frontend/src/lib/stores/social.ts:
      • socialActions.initialize(socket: Socket | null):
        • Stores socket, starts/stops HTTP presence fallback.
        • When socket present, binds:
          • onchannelmessage → handleIncomingMessage
          • onchannelpresence → handlePresenceUpdate
          • onstatuspresence → handleStatusPresence
          • onnotification → handleNotification
        • Loads initial data: loadFriends, loadFriendRequests, loadChatChannels.
      • loadFriends():
        • Calls /api/social/friends, maps to Friend objects, then socket.followUsers(friendIds) when socket exists.
      • Instrumentation added:
        • handleStatusPresence: console.log(“social: status presence update”, statusPresence);
        • handleNotification: console.log(“social: notification received”, notification);
  • Social Hub page:

    • frontend/src/routes/social/+page.svelte:
      • Imports ensureSocket and calls initializeSocial() in onMount when $user is truthy.
      • initializeSocial:
        • Tries ensureSocket() inside inner try/catch.
        • On failure: warns and sets socket = null (HTTP-only mode).
        • Calls await socialActions.initialize(socket) either way.
        • Logs Social features initialized successfully with { hasSocket: !!socket }.
      • Connection error UI with Retry button.

Mock Data Cleanup & Discover Consolidation (Phase C)

  • Chat mocks removed:

    • frontend/src/lib/stores/social.ts:
      • loadChatChannels() → chatChannels.set([]).
      • loadChannelMessages(channelId) → ensures empty array, no fake messages.
    • frontend/src/lib/components/social/Chat.svelte:
      • Still functional UI, but uses the now-empty stores.
  • Discover Players tab removed in code:

    • frontend/src/routes/social/+page.svelte:
      • Left-nav buttons: Friends, Messages, Activity Feed, Privacy Settings only.
      • The entire {:else if activeTab === ‘discover’} block was deleted in repo.
  • Discover functionality lives in Friends list:

    • FriendsList.svelte:
      • Discover button toggles a search panel.
      • Hints:
        • “Type at least 2 characters to search”
        • “No players found” states.
      • Search calls /api/social/search?q=…&limit=10.

Search backend

  • frontend/src/routes/api/social/search/+server.ts:
    • Guards: auth required, q length >= 2, limit ≤ 50.
    • Uses NakamaAPI.getClient().getUsers(ms, [], [query]) → username-based search.
    • Filters:
      • Excludes self.
      • Excludes already-friends (via nakama.getFriends).
    • Returns { id, username, displayName: u.display_name || u.username, avatarUrl }.

Playwright MCP check (production)

  • Playwright MCP navigated to https://funday.gg/social and captured a full-page screenshot.
  • Snapshot shows:
    • Social Hub header OK.
    • Left nav still includes “Discover Players”.
    • Friends card shows “Discover Players” button with old copy.
  • Console output:
    • Unexpected token ’%’ (needs investigation).
    • Manifest enctype warning (harmless).
    • Performance logs (Lighthouse 100/100).

Conclusion: repo and production are out of sync; production is still on old social build (pre-cleanup), even though fixes are implemented in the code.


3. Your Tasks (Next Agent) — /go with /test + /fix + /pp

A. Sync & Deploy

  1. Confirm repo state:
    • Re-open the files listed above to ensure no regressions.
  2. Build & deploy the frontend with these social changes to the environment behind https://funday.gg
    (follow the project’s usual deploy workflow; avoid violating the “private project” rule).

B. /test — Hyper-efficient E2E Verification

Use Playwright and/or Puppeteer (via MCP or local) to run production E2E:

  • Flows to test:

    • Friend count matches between Profile and Social Hub.
    • Add Friend from:
      • Profile page.
      • Friends search.
      • Check “Request Sent” behavior and disabled button.
    • Self-friend-request:
      • Attempt from own profile → rejected client-side + API returns 400.
    • Presence:
      • Two browsers with two accounts.
      • Verify:
        • Friends list online/offline flags update in real time.
        • social: status presence update logs appear.
    • Notifications:
      • Send friend request.
      • Verify:
        • social: notification received logs.
        • Toast displays “sent you a friend request”; optional desktop notification.
    • Search:
      • Ensure Discover UI only inside Friends list.
      • Check empty-state messages and behavior for short queries and no results.
    • Mock data:
      • No fake chat channels/messages visible anywhere.
  • Technical checks:

    • Console: ensure no blocking errors remain.
      • Investigate and fix Unexpected token ’%’ (likely from some script or JSON parse).
    • Network: watch Nakama socket connection and events if possible.

C. /fix — Issues to Hunt & Harden

  • Production vs repo mismatch:
    • Verify that after deploy:
      • Discover Players tab is gone in production.
      • Social Hub left nav reflects the repo state.
  • Console Unexpected token ’%’:
    • Trace back to script/response causing it.
    • Fix root cause (bad JSON, malformed inline script, etc.) and re-test.
  • Search by displayName (future-hardening):
    • Currently username-based only.
    • Optionally design/implement a Nakama-side RPC + index for true displayName search (documented but not implemented yet).

For each fix, follow /fix steps: deep reasoning → implement → re-run relevant tests.

D. /pp — Prove Perfection

Once you are satisfied that production matches expectations:

  1. Use Playwright MCP (or local Playwright) to capture a production screenshot:
    • Target: /social and optionally profile page.
  2. Copy screenshot as per pp.md:
    • cp /tmp/playwright-mcp-output/*/capture.png /home/usr/funday/games/assets/_dev/screenshots/YYYYMMDDhhmm_Social-System_Success.png
  3. Deliver in chat:

“md Mission Complete

Final verification: Funday Social System (friends/presence/notifications/search/UX) is fully operational in production, aligned with identity SSOT, and free of mock data. Ready for production. ✅ “


4. Final Word to You (Next Agent)

You’re stepping into a codebase where:

  • Identity SSOT is solid, and social code is largely aligned with it.
  • The key remaining work is verification, deployment alignment, and tiny edge-case fixes.
  • You have workflows: /go, /test, /fix, /pp, and a rich docs ecosystem under docs/ and frontend/src/lib/stores.

Please:

  • Triple-check everything.
  • Treat Playwright/Puppeteer + console logs + screenshots as your truth.
  • Only declare /pp when production visually and behaviorally proves the six social priorities.

Funday Social – Current Fixes & Next Steps

What’s already done (this session)

  • Identity diagnostics

    • App.Locals now has identitySource: "nakama" | "local_fallback".
    • hooks.server.ts:
      • Sets identitySource when loading from funday-identity cookie.
      • Sets identitySource = "nakama" for real guest sessions.
      • Sets identitySource = "local_fallback" when Nakama auth fails.
    • +layout.server.ts exposes identitySource in layout data.
  • Social API guarding (Plan Step 2)

    • All /api/social/* endpoints now short-circuit when identitySource === "local_fallback":
      • Return: 503 with { error: "Social services temporarily offline", offline: true }.
    • Endpoints updated:
      • /api/social/friends (GET/POST/DELETE/PATCH)
      • /api/social/activity (GET)
      • /api/social/presence (GET)
      • /api/social/search (GET)
  • Frontend offline handling

    • socialActions.loadFriends():
      • Interprets offline: true from /api/social/friends.
      • Sets socialError = "Social services temporarily offline" and stops.
    • socialActions.addFriend():
      • Interprets the same offline flag and surfaces socialError.
    • socialActions.refreshPresence():
      • Interprets offline flag from /api/social/presence and logs a warning instead of crashing.
    • FriendsList.svelte already shows $socialError in a red alert at the top, so the user sees a clear offline banner when backend social is unavailable.

Still TO DO (for you)

  1. Root-cause Nakama reachability (avoid local_fallback)

    • Inspect logs from hooks.server.ts:
      • Look for Nakama guest auth failed, creating local fallback.
    • Verify Nakama service from the frontend pod:
      • Confirm host/port/SSL (matches NakamaAPI config).
    • Fix infra/env so most sessions use identitySource = "nakama".
  2. Unify ensure-session with consolidated identity

    • src/routes/api/auth/ensure-session/+server.ts still uses legacy funday-session / funday-user.
    • Update it to:
      • Write funday-identity in the same shape as hooks.server.ts.
      • Set identitySource: "nakama" | "local_fallback".
    • Goal: one single identity model regardless of entrypoint (games vs web).
  3. Fix %PUBLIC_NAKAMA_*% error

    • src/app.html still has inline script with %PUBLIC_NAKAMA_HOST% etc.
    • Replace this with a SvelteKit-native env approach:
      • Create src/lib/config/public.ts using $env/static/public.
      • In root layout onMount, set window.__FUNDAY_CONFIG__ based on that.
      • Remove the %...% script from app.html and rebuild.
    • Confirm that “Unexpected token ’%’” disappears from console.
  4. Deploy + verification + proof (pp)

    • Rebuild frontend and deploy following Environment Sync & Deployment Protocol.
    • Use Playwright / Puppeteer on https://funday.gg/social to:
      • Verify:
        • Correct nav (no “Discover Players” tab).
        • Friends, requests, search, presence, notifications behave correctly on a real Nakama identity.
        • Offline state appears only when we intentionally simulate Nakama outage.
    • Then run the pp workflow:
      • See /home/usr/funday/.windsurf/workflows/pp.md for the PERFECTION protocol.
      • Capture a production screenshot (Social Hub + working flows).
      • Copy to games/assets/_dev/screenshots/ as per naming convention.
      • Post the final Markdown block with !Mission Complete and a one-line summary.

Until those steps are done, consider Social “architecturally ready + behaviorally guarded”, but not yet fully proven in production.

summary (/ys):
  identity_diag:
    - Added identitySource typing in App.Locals and hooked it through hooks.server.ts + layout load.
    - Consolidated cookie now carries identitySource ("nakama" | "local_fallback") and logs include it.
    - Layout data exposes identitySource so UI/tests can see whether session is real or fallback.
  social_state:
    - Existing repo Social Hub already aligned with SSOT (friends API, guards, sockets, mock removal).
    - Production still on older build (discover tab visible); deployment sync pending.
    - Console still throws `Unexpected token '%'` from app.html placeholder script.
  outstanding:
    - Social APIs/UI still treat fallback sessions like real ones (needs guard/offline mode).
    - ensure-session endpoint still issues legacy cookies; not yet unified with consolidated identity.
    - Deployment + verification + proof steps untouched this session.
 
plan (/yp):
  - guard_social_offline:
      description: Detect `identitySource === "local_fallback"` in API routes (/api/social/*) and return clear “backend offline” responses; front-end should show an offline banner instead of half-working UI.
      steps:
        1. Update social API handlers (friends, presence, activity, search) to short-circuit when locals.identitySource !== "nakama".
        2. In social store/page, read layout’s identitySource and render an “offline social” state plus console warning.
        3. Add regression test (Playwright or unit) ensuring fallback identity cannot send friend requests.
  - unify_session_paths:
      description: Make `/api/auth/ensure-session` reuse the consolidated cookie format + set identitySource, so all session creation paths behave identically.
      steps: 1. Replace legacy funday-session/funday-user writes with funday-identity payload.
        2. Ensure Redis cache + locals are updated consistently.
        3. Log metrics (guestSessionCreated) with source labels for observability.
  - fix_percent_error:
      description: Remove `%PUBLIC_NAKAMA_*%` script in app.html, replace with SvelteKit env-driven `window.__FUNDAY_CONFIG__`.
      steps: 1. Create `src/lib/config/public.ts` reading `$env/static/public`.
        2. In root layout onMount, set `window.__FUNDAY_CONFIG__ = config`.
        3. Delete the inline script from app.html and rebuild to confirm console clean.
  - deploy_and_verify:
      description: Build frontend (adapter-node) and restart `funday-frontend.service`, then run full `/test` matrix.
      steps: 1. `npm run build` in frontend, deploy via systemd path.
        2. Use Playwright MCP to re-check /social (nav, discover removal, friend flows).
        3. Capture screenshot + narrative `/pp`.

I didn’t have time to run Steps 2–4 above in this session, so production still shows the outdated Social Hub and the % console error; please treat those as the immediate follow-ups.

ingress_routing_explained:

before_cleanup: # 🚨 CHAOS funday_platform_ingresses: - name: “funday-ingress” routes: - “/game-servers → networked-snake-service:80” - “/game-servers/pong-multiplayer → pong-game-service:80” - “/game-servers/tictactoe-multiplayer → tictactoe-game-service:80” - “/console, /v2/console, /v2 → nakama:7350/7351” - ”/ → sveltekit-frontend:80” problem: “MIXED game servers + Nakama + frontend in ONE ingress”

  - name: "networked-snake-ingress"
    routes:
      - "/game-servers/networked-snake-multiplayer → networked-snake-service:80"
    problem: "DUPLICATE game server routing"

  - name: "nakama-https-ingress"
    routes:
      - "/v2, /console → funday-platform/nakama services"
    problem: "Routing to STALE Nakama deployment"

nakama_namespace_ingresses:

    routes:
      - "/console, /v2, /ws → nakama/nakama services (LIVE)"
    problem: "CONFLICTS with funday-platform ingresses"

after_cleanup: # ✅ CLEAN funday_platform_ingresses: - name: “funday-ingress-https” routes: - ”/ → sveltekit-frontend:80” purpose: “Main frontend serving (VALID)”

  - name: "funday-admin-ingress"
    routes:
      - "gitea.funday.local → gitea-http:3000"
    purpose: "Admin Gitea interface (VALID)"

  - name: "nakama-console"
    routes:
      - "nakama-console.funday.gg/ → nakama-console:7351"

result: - ”✅ No ingress conflicts” - ”✅ Game servers NO LONGER have dedicated routing” - ”✅ All games served via frontend plugin system” - ”✅ Nakama routes ONLY in nakama namespace”

game_architecture_explained:

before: # 🎮 Dedicated K8s Servers snake_pong_tictactoe: frontend: “HTML/JS client in /games/{game}/” backend: “K8s Deployment (Go/Node.js server)” connection: “WebSocket to dedicated pod” routing: “/game-servers/{game} → game-service:80” complexity: “HIGH (K8s + code + monitoring + scaling)”

after: # 🌐 Web-Based Plugin System pong: frontend: “PongGame.svelte component” backend: “Nakama matchmaking (when needed)” connection: “Nakama realtime/matches API” routing: “/play/pong → SvelteKit native component” complexity: “LOW (just frontend code)”

snake:
  frontend: "Placeholder index.html"
  backend: "None (needs reimplementation)"
  connection: "N/A"
  routing: "/play/snake → iframe placeholder"
  complexity: "PENDING WEB IMPLEMENTATION"

benefits: - ”✅ No K8s deployments to maintain” - ”✅ Instant deployment (static files)” - ”✅ Easier local development” - ”✅ Consistent with other web games”

🧭 Next Agent Onboarding – Presence / “Offline” Bug + Connect4 PvP + Flaws Scan

Speaking directly to you, next agent.

Your mission is to run /shine and /flaws on this project with a very specific context.


1️⃣ Context Echo (what you’re solving)

context: >
  Funday gaming platform (SvelteKit + Nakama): figure out why players appear
  OFFLINE in social/presence ("sizial") UIs even when actually online,
  and how this ties into Connect4 PvP & other Nakama-based matches
  (match labels, presence, session-token bridge, iframe games, plugin assets).
goals:
  - Build deep cheat-sheet-level overstanding of identity + presence + PvP flows
  - Map and explain all causes of "online but shown offline" in this codebase
  - Forensically sniff flaws (architecture, bugs, smells) and output a rescue blueprint
workflows_to_use:
  - /shine
  - /flaws

2️⃣ Systems You MUST First

Use these as anchors for your /shine deep-dive and /flaws static analysis:

  • Funday Identity & Sessions (SSOT)

    • Single cookie: funday-identitydeviceId + session (Nakama JWT + userId/username) + user (username/displayName/avatar).
    • Source: see identity docs in docs/02-development/IDENTITY-*.md (per memory), and code in:
      • frontend/src/hooks.server.ts
      • frontend/src/lib/server/identityCookieHelper.ts (or similarly named helper)
      • frontend/src/lib/auth/*.ts or similar
    • Memory used: Guest-First Authentication Pattern + Funday Identity Management - Single Source of Truth.
  • Presence / “Online vs Offline” Semantics

    • Likely tied to:
      • Nakama presence (WebSockets, heartbeats, matches/channels).
      • Our own “social / sizial” UI that displays who’s online/offline.
    • You must map: what the UI calls “online” vs what Nakama / backend considers “present”.
  • Game Plugin / Match Architecture

    • Filesystem plugin system:
      • Real games under frontend/static/game-plugins/* and /game-plugins symlinks.
      • API: frontend/src/routes/api/games/+server.ts.
    • Matchmaking + Nakama:
      • Core modules in /nakama-modules/ (TS + Lua).
      • Example: nakama-modules/connect4_match.lua, nakama-modules/racing_match.lua, nakama-modules/index.ts RPCs.
  • Connect4 PvP Critical Path

    • High-level mission doc: 00_PRT_drawer-nakama-matches.md (already open).
    • Relevant files:
      • frontend/src/lib/components/games/GameDrawer.svelte
        (match drawer: listing, join, session-token postMessage into iframe).
      • games/connect4/index.html
        (iframe game, uses Nakama JS SDK & session-token from parent).
      • frontend/src/routes/play/[id]/+page.server.ts
        (cache-busting of game HTML, param versioning).
      • /nakama-modules/connect4_match.lua
        (authoritative match; label encodes game/open/players/creator info).
      • /nakama-modules/index.ts
        (find_match_v3 etc – builds label, passes creator info).
    • Memory used: Connect4 Multiplayer Complete Fix.
  • Racing / Other Matches as Patterns

    • Open now: nakama-modules/racing_match.lua – lightweight authoritative lobby:
      • Manual JSON json_encode, count_players, broadcast_state.
      • Good reference for how labels & state are exposed to clients.
  • Frontend Tech Stack

    • SvelteKit 2 + Svelte 5, Tailwind 4 + DaisyUI 5.
    • Svelte MCP server is available – must use it for Svelte code (per rules).
    • Memory used: Funday Gaming Platform Tech Stack.
  • Infra / Ops Constraints

    • Frontend runs via systemd (funday-frontend.service), not Docker.
    • This is a private project on a private server – never push/publish to GitHub or external repos.

3️⃣ How to Run /shine for Maximum Value

When you invoke /shine, set:

context: >
  Funday presence / online-state and social ("sizial") UI, Connect4 PvP
  match lifecycle (listing → join → game iframe), Nakama matches (Lua/TS),
  identity SSOT (funday-identity cookie), and how all this produces cases
  where users are actually online/playing but rendered as OFFLINE in UIs.

Your /shine deliverable should be:

  • An ultra-condensed cheat sheet (markdown) explaining:

    • Identity flow: browser ⇄ funday-identity ⇄ hooks ⇄ Nakama session.
    • Presence flow: WebSocket / match presence / labels → any “friends/online” or “players in lobby” lists.
    • Connect4 PvP flow end-to-end:
      • GameDrawer → RPC (find_match_v3) → Nakama match creation/join → iframe load → session-token handoff → Nakama JS SDK connect → game start.
    • Offline-but-online scenarios specific to this codebase (not just theory):
      • Where presence/labels are computed.
      • Where lists are read (drawer, social/sizial UI, in-game lobby, etc.).
      • Where caching, heartbeats, or identity mismatch might cause stale “offline”.
  • Use web + Nakama docs MCP + Svelte MCP + context7 to:

    • Refresh latest best practices on presence models (Nakama, game backends).
    • Compare our flows vs recommended patterns (presence streams, heartbeats, labels).

4️⃣ How to Run /flaws (Static Forensic Sweep)

The /flaws workflow is already parameterized:

source: "*"
output: "docs/2Fix_FLAWS.md"

When you execute /flaws, focus your forensic lens especially on:

  • Identity / Presence

    • Any divergence from the SSOT rules (Nakama updated but cookie not, or vice versa).
    • Multiple identity keys used inconsistently (userId, username, guest IDs, device IDs).
    • Any direct usage of funday-session, funday-user, or old cookies (should be consolidated).
  • PvP / Match Flows

    • nakama-modules/index.ts RPCs – especially find_match_v3, any Connect4- / racing-related RPCs.
    • Lua matches:
      • connect4_match.lua
      • racing_match.lua
      • Others under /nakama-modules/ that emit labels or state.
    • Frontend match UI:
      • GameDrawer.svelte
      • Any “friends/online” / “social/sizial” components or stores.
  • Games Assets & Bridge

    • frontend/src/routes/games/assets/[...path]/+server.ts (just touched).
    • games/connect4/index.html (Nakama JS SDK load order, token handling, reconnection).
    • /games/assets/_sdk/funday-nakama.js and any CDN usage.

Your docs/2Fix_FLAWS.md should follow the /flaws spec:

  • 🎯 Briefing – Intent + top flaws + first concrete fix.
  • 💔 Reality Map – Tree/flows/heatmap; where presence & matches actually flow.
  • 🐛 Flaw Forensics – Root causes, security/perf/debt.
  • ✨ Potential & Salvage – What’s good and reusable.
  • 🛠️ Rescue Blueprint – Phased tasks (MVP now, later polish).
  • 📊 Visuals – 3–4 Mermaid diagrams:
    • Presence & identity flow.
    • Connect4 PvP flow.
    • Flaw heatmap.
    • Revamp roadmap.

5️⃣ Suggested Execution Order (Checklist)

For you, next agent:

  • Skim these key files/docs:
    • 00_PRT_drawer-nakama-matches.md
    • /nakama-modules/index.ts
    • /nakama-modules/connect4_match.lua
    • /nakama-modules/racing_match.lua
    • frontend/src/lib/components/games/GameDrawer.svelte
    • games/connect4/index.html
    • Identity docs under docs/02-development/IDENTITY-*.md
  • Run /shine with the context above, produce cheat-sheet markdown.
  • Run /flaws over the repo, write docs/2Fix_FLAWS.md with Mermaids + phased plan.
  • From your /shine + /flaws outputs, design a concrete set of next coding tasks:
    • Fix presence/online-state mismatches.
    • Harden Connect4 PVP start + reconnection + iframe bridge.
    • Align all match labels & lists with a consistent presence model.

6️⃣ Status From This Agent

  • I did not modify any code for this step.
  • I relied on the following memories:
    • Connect4 Multiplayer Complete Fix
    • Guest-First Authentication Pattern
    • Funday Gaming Platform Tech Stack
    • Plugin System Architecture
    • Funday Identity Management – Single Source of Truth
  • Your job is now to go deep with /shine and then tear the flaws apart with /flaws, turning everything into a precise rescue blueprint.

Task List

  • 1. Social Chat UX

    • 1.1 Fix social.ts Chat Management block:
      • Restore a valid loadChatChannels body (no-op + error logging).
      • Refactor sendMessage(channelId, content) to:
        • Always append an optimistic ChatMessage (with current user’s displayName/avatar).
        • Call updateChannelLastMessage(channelId, message).
        • Send via socket if available; otherwise just keep local history.
      • Ensure loadChannelMessages uses normalizeChatContent and updates lastMessage.
    • 1.2 Update handleIncomingMessage:
      • Enrich from friends for displayName/avatarUrl.
      • Use normalizeChatContent to avoid [object Object].
      • Update chatMessages and updateChannelLastMessage.
      • Preserve unread counter behavior from the original implementation.
    • 1.3 Confirm Chat.svelte channel list shows last message snippet instead of No messages yet whenever messages exist.
  • 2. Avatars in all chats

    • 2.1 Verify /api/chat/room enrichment (username, displayName, avatarUrl) is used by:
      • /chat page.
      • GameDrawer lobby/match chat.
    • 2.2 Ensure social DM history + realtime messages always populate displayName and avatarUrl (friends-based first, fallback to Nakama message fields).
    • 2.3 Confirm Avatar components across social/global/lobby chats all use avatarUrl from Nakama.
  • 3. Friends count & buttons (Profile vs Social)

    • 3.1 On /profile client:
      • Call socialActions.loadFriends() on mount if not already loaded.
      • Compute friendCount = $friends.length || data.stats.friends || 0.
      • Compute isFriend from $friends only (some(f.id === displayUser.id)).
    • 3.2 Ensure “Add Friend” button:
      • Is disabled while request in-flight.
      • Switches to “Message” as soon as the request is accepted and the friends store updates.
    • 3.3 Verify /profile and /sozial show identical friend counts after any friend action.
  • 4. Profile self vs others

    • 4.1 Avatar label:
      • Use $displayText only for own profile.
      • Use displayUser.displayName || displayUser.username for other users.
    • 4.2 Hide session debug card when viewing someone else’s profile (isOwnProfile && currentSession).
    • 4.3 Review bottom sections for any other “own account only” info and guard them with isOwnProfile.
  • 5. Profile Recent Activity integration

    • 5.1 In +page.server.ts, keep leaderboard loop strictly for stats.gamesPlayed and stats.playTime.
    • 5.2 After stats, call /api/social/activity and set activity = data.activity || [].
    • 5.3 Update +page.svelte Recent Activity rendering to primarily use:
      • item.title / item.description (from /api/social/activity).
      • Fallback to legacy leaderboard display if needed.
    • 5.4 Confirm friend adds and games played appear as “Recent Activity” on profile, matching Social Hub.
  • 6. Notifications & toasts

    • 6.1 Review social.ts.handleNotification and map:
      • Friend request → primary/info toast variant.
      • Friend accept → success.
      • Match invite → warning/accent.
      • Generic → neutral/info.
    • 6.2 Ensure toast component visually reflects variants with distinct colors via DaisyUI.
    • 6.3 Verify that:
      • Friend requests/accepts.
      • Match invites.
      • Other social notifications all produce appropriate toasts and (where applicable) background notifications.
  • 7. Game lobby chat

    • 7.1 In GameDrawer.svelte:
      • Ensure loadChat() obtains a valid Nakama socket (or clearly falls back to HTTP polling) before calling joinChat.
      • Keep socket.onchatmessage scoped so it doesn’t conflict with other socket handlers.
    • 7.2 Confirm:
      • History loads via /api/chat/room.
      • New messages appear immediately via WebSocket.
      • Avatars/names are consistent with Nakama profiles.
    • 7.3 Add a minimal guard/logging if joinChat fails so failures are visible in console.
  • 8. Global /chat

    • 8.1 Validate globalRoom('general') output vs assertRoomName expectations.
    • 8.2 Inspect /api/chat/room responses in browser devtools when /chat loads/sends:
      • Fix any 4xx/5xx (e.g., invalid name, session issue).
    • 8.3 Optionally (later): plan migration of /chat to share the realtime socket used by Social to make it feel more instant.
  • 9. Regression/cleanup

    • 9.1 Ensure social.ts exposes all methods referenced in initialize:

      • startPresenceFallback, stopPresenceFallback, handlePresenceUpdate, handleStatusPresence, handleNotification, loadInitialNotifications, refreshProfilesForChat, disconnect, clearError.
    • 9.2 Run TypeScript build to confirm no lints/errors remain in social.ts and related social components.

    • 9.3 Basic manual pass:

      • /sozial friends + chat.
      • /profile self and another user.
      • /chat.
      • Game lobby chat via GameDrawer.

      Onboarding Prompt for Next Agent – Social/Profile/Chat Fixes

You’re taking over work on Funday’s social/profile/chat system. This is a SvelteKit (Svelte 5 + runes) frontend talking to Nakama via custom APIs. The goal: make social UX seamless and consistent across Profile, Social Hub, global /chat, and game lobby chat.


1. High-Level Context

  • Core features involved

    • Friends system (/sozial + social widget)
    • User profile (/profile?userId=...)
    • Social DM/chat widget (bottom-right bubble on Social page)
    • Global chat (/chat)
    • Game lobby/match chat (GameDrawer in-game sidebar)
    • Notifications/toasts for social events (friend requests, accepts, match invites, etc.)
  • Key requirement

    • Single source of truth for:
      • Friend list & counts → friends store (social.ts) / /api/social/friends.
      • Avatars & names → Nakama user profiles (avatar_url, display_name, username).
      • Activity feed → /api/social/activity (Nakama storage "user_activity").
  • Main user pain points

    • Avatars not matching Nakama (missing avatar URL / default labels) in chats.
    • Social widget “Messages” list: shows "No messages yet" even when there are messages; preview/count inconsistent.
    • /profile friend count differs from /sozial; friend button sometimes only updates after clicking again.
    • Profile UX doesn’t clearly change between “my profile” vs “someone else’s”.
    • Profile “Recent Activity” not showing new friends/games, only a static “No activity yet”.
    • Notifications should be toast-based, with clear color per event type.
    • Global /chat and game lobby chat “used to work” but currently feel broken or unreliable.

2. Important Files & How They Interact

Social / Friends / Chat Store

  • frontend/src/lib/stores/social.ts

    • Exports:
      • friends, friendRequests, chatChannels, chatMessages, activeChatChannel, socialSocket, socialLoading, socialError.
      • Derived: onlineFriends, offlineFriends, pendingFriendRequests, activeChatMessages, totalUnreadMessages.
      • socialActions with methods:
        • initialize(socket): wires Nakama socket → sets onchannelmessage, onchannelpresence, onstatuspresence, onnotification, loads friends/requests/chat channels/notifications, refreshes profiles for chat.
        • Friend management: loadFriends, addFriend, removeFriend, blockFriend, loadFriendRequests, acceptFriendRequest, declineFriendRequest.
        • Chat:
          • Currently mid-refactor and inconsistent – see “Current state” below.
        • Notifications: handleNotification maps Nakama notifications into toastActions.* + background notifications.
        • Presence: refreshPresence, startPresenceFallback, stopPresenceFallback.
        • Utility: clearError, disconnect.
  • Current state (important)

    • We introduced:
      • normalizeChatContent(raw) helper at bottom.
      • updateChannelLastMessage(channelId, last) helper.
      • handleIncomingMessage now:
        • Uses friends store to enrich displayName and avatarUrl.
        • Uses normalizeChatContent to avoid [object Object].
        • Updates chatMessages[channelId] and updateChannelLastMessage.
    • BUT the “Chat Management” block around loadChatChannels / sendMessage / loadChannelMessages was partially patched and is syntactically inconsistent with the original version:
      • loadChatChannels body is incomplete.
      • sendMessage and loadChannelMessages are now tightly coupled to Nakama listChannelMessages and updateChannelLastMessage, but need cleanup so TypeScript compiles and semantics are correct.
    • Also, refreshProfilesForChat exists (from HEAD); it reloads friends and rewrites chatMessages to add current displayName / avatarUrl.

Social Hub & Chat Components

  • Social Hub page – frontend/src/routes/social/+page.svelte

    • On mount:
      • If $user, calls initializeSocial() which:
        • ensureSocket() → tries to connect a Nakama socket, falls back to HTTP-only mode if it fails.
        • Calls socialActions.initialize(socket) to wire listeners and load base data.
      • Calls loadActivity() from /api/social/activity.
    • Left column:
      • Social navigation.
      • “Your Social Stats”, showing $friends.length and $onlineFriends.length.
    • Right column:
      • Tabs: friends, chat, activity, settings.
      • Currently the “Messages” tab only shows a placeholder card; does not yet embed the Chat.svelte widget there.
    • Chat widget (floating bubble bottom-right) only renders when $user && $socialSocket.
  • Social chat widget – frontend/src/lib/components/social/Chat.svelte

    • Uses chatChannels, activeChatMessages, totalUnreadMessages, socialActions, socialSocket, activeChatChannel.
    • Channel list (when no active channel):
      • Shows each $chatChannels entry with:
        • Icon (emoji).
        • Channel name.
        • channel.lastMessage?.timestamp for time.
        • channel.lastMessage?.content preview; else "No messages yet".
    • Active chat:
      • Uses $activeChatMessages.
      • Renders avatars with message.avatarUrl and message.displayName || message.senderUsername.
    • Implication: For “Messages” list to show something other than “No messages yet”, you must:
      • Populate chatChannels with lastMessage.
      • Keep lastMessage updated on history load + every new message.
  • Generic chat window – frontend/src/lib/components/social/ChatWindow.svelte

    • More generic multi-user chat component (used elsewhere).
    • Uses Avatar with message.avatar and user.avatar.
    • Good reference for how avatar/name/time layout should look.

Profile

  • Profile server load – frontend/src/routes/profile/+page.server.ts

    • Input:
      • userId query param; falls back to locals.session.userId.
      • isOwnProfile = targetUserId === locals.session.userId.
    • Behavior:
      • Fetches Nakama user profile for targetUserId → builds profileUser object with id, username, displayName, avatarUrl, createdAt, lastSeen.
      • Fetches leaderboards and aggregates:
        • stats.gamesPlayed (count of leaderboards where the user has a record).
        • stats.playTime (score sum / 60 as “hours”).
        • Forms a simple activity list with type "leaderboard", leaderboard, score, rank, timestamp based on leaderboard records.
      • Fetches /api/social/friends:
        • stats.friends = friendsList.length.
        • If viewing someone else’s profile (!isOwnProfile && targetUserId), tries to see if that user is in friendsList → sets isFriend and enriches profileUser.status + lastSeen.
    • Return to client:
      • { user: profileUser ?? locals.user, session, stats, activity, isFriend, isOwnProfile }.
  • Profile page (client) – frontend/src/routes/profile/+page.svelte

    • Uses Svelte 5 runes.

    • Current key logic:

      let { data }: { data: PageData } = $props()
      let currentSession: NakamaSession | null = $state(null)
      session.subscribe((s) => (currentSession = s))
       
      let displayUser: User | null = $derived(data?.user || $user || null)
      let isOwnProfile = $derived(data?.isOwnProfile ?? false)
       
      let isFriend = $derived(!!(displayUser && $friends.some((f) => f.id === displayUser.id)))
      let friendCount = $derived($friends.length || data.stats?.friends || 0)
       
      onMount(() => {
        // Ensure social store is hydrated so profile counts/buttons stay in sync
        socialActions.loadFriends().catch(() => {})
      })
    • Header:

      • Avatar presently uses:
        <Avatar
          src={displayUser?.avatarUrl}
          name={isOwnProfile
            ? $displayText
            : displayUser?.displayName || displayUser?.username || 'Player'}
          size="xl"
          ring
        />
      • For own profile: DisplayNameEditor + handle.
      • For others: static heading with displayUser.displayName or username.
    • Stats:

      • Friends stat uses friendCount (now derived from store, with data.stats.friends as fallback).
    • Recent Activity:

      • Renders data.activity built on server from leaderboard stats only.
      • Does not yet consume /api/social/activity’s richer activity types.
    • Bottom debug “Session Info”:

      • Now should be shown only when isOwnProfile && currentSession.

API Endpoints

  • Friends – frontend/src/routes/api/social/friends/+server.ts

    • GET returns { friends, requests } (with avatarUrl, displayName, status, etc.).
    • POST sends friend request by username and appends "friend" activity to Nakama storage (user_activity).
    • PATCH handles block/unblock/accept/decline, and on accept also appends "friend" activity.
  • Activity – frontend/src/routes/api/social/activity/+server.ts

    • Reads user_activity storage entry for the current user.
    • Returns { activity: formattedActivities } with:
      • type, gameId, result, score, rank, timestamp, title, description, etc.
    • Already used on Social Hub.
  • Chat (room) – frontend/src/routes/api/chat/room/+server.ts

    • GET:
      • Uses Nakama socket to joinChat(name, 1, false, false) to get channelId.
      • Then listChannelMessages on the real channelId.
      • Enriches messages with Nakama getUsersusername, displayName, avatarUrl.
    • POST:
      • Creates socket, joins channel, sends message { content }, disconnects.
  • Global chat UI – frontend/src/routes/chat/+page.svelte

    • Uses renderChatContent to render message content (handles object vs string).
    • Uses /api/chat/room GET/POST.
    • Polls every 5 seconds.
  • Game chat – frontend/src/lib/components/games/GameDrawer.svelte

    • Lobby/match chat:
      • Uses computeChannelName() (game lobby or match room).
      • History: /api/chat/room?name=....
      • Realtime: socket.joinChat from $gameContext.socket, sets socket.onchatmessage, appends to chatMessages.
      • Send: tries WebSocket writeChatMessage(chatChannelId, { content }), fallback to /api/chat/room POST.

3. Current Issues & Likely Root Causes

  1. Messages list always says “No messages yet”

    • Because ChatChannel.lastMessage is rarely set.
    • Need to:
      • Create DM channels with lastMessage after history load or message send.
      • On every incoming message (handleIncomingMessage), call updateChannelLastMessage.
  2. Avatars sometimes wrong/missing in chats

    • For social DM: depends on displayName/avatarUrl being set in ChatMessage.
    • We added normalizeChatContent and partial avatar enrichment but must:
      • Ensure loadChannelMessages from DM and from room chats sets displayName/avatarUrl correctly.
      • Ensure handleIncomingMessage uses friends data or Nakama message data consistently.
  3. Profile vs Social Hub friend count mismatch

    • Profile now uses store, but only after socialActions.loadFriends() finishes.
    • On direct /profile visits, there may be a short window where $friends is empty (0) even though /sozial would show a correct count once initialized.
    • This is acceptable if short-lived, but ideally:
      • Show server stats.friends until store hydrates (current friendCount already uses $friends.length || stats.friends).
    • Ensure loadFriends resolves quickly and does not get blocked by errors.
  4. Friend button not instantly updating

    • socialActions.addFriend reloads friends and requests; isFriend now computed from store.
    • Need to confirm:
      • Accept flow: when user accepts, friends reload and isFriend flips to true.
      • Possibly still relying on server isFriend in some flows – ensure UI solely uses store.
  5. Profile self vs others

    • Avatar label + session debug have been updated, but:
      • Confirm no other own-only info leaks into other profiles (e.g., email maybe should be hidden for other users, depending on UX decision).
  6. Profile Recent Activity not showing social events/games

    • Server load still constructs activity from leaderboard stats instead of /api/social/activity.
    • Need to plug /api/social/activity into profile load, and adjust rendering.
  7. Notifications/toasts color-coding

    • handleNotification already uses toastActions.info/success, but the visual mapping to DaisyUI styles might not be clearly distinguished.
    • Likely requires checking toast component implementation and ensuring variant->class mapping is correct.
  8. Game lobby chat & global chat regressions

    • Game lobby:
      • Potential issues with socket availability, joinChat failures, or inconsistent message shapes between WebSocket and HTTP history.
    • Global chat:
      • Must validate /api/chat/room with globalRoom('general') output; any HTTP errors would break /chat.

  1. Stabilize social.ts Chat Management

    • Compare current social.ts with git show HEAD:frontend/src/lib/stores/social.ts.
    • Reconstruct Chat Management section so it is:
      • TypeScript-compilable.
      • Uses normalizeChatContent and updateChannelLastMessage.
      • Keeps behavior of:
        • Optimistic append on send.
        • Proper DM handling (sendDirectMessage, loadDirectMessages, openDirectMessage).
        • Channel history loading (loadChannelMessages + loadChatChannels).
    • Confirm handleIncomingMessage:
      • Enriches displayName/avatarUrl.
      • Normalizes content.
      • Updates lastMessage and unreadCount.
  2. Wire channel previews

    • Ensure:
      • After openDirectMessage, chatChannels includes that channel and lastMessage is set after history load.
      • On every incoming or sent DM, updateChannelLastMessage runs.
    • Then check Chat.svelte: the “Messages” list should show last message text + timestamp, not “No messages yet”.
  3. Finish Profile–Social consistency

    • Verify the on-mount socialActions.loadFriends() on /profile and the derived isFriend/friendCount.
    • Add any missing guards or spinners so user doesn’t see a long-lived 0 count.
  4. Plug /api/social/activity into Profile

    • In +page.server.ts, call /api/social/activity and replace activity with its activity array (keeping leaderboard-only stats just for stats.gamesPlayed/playTime).
    • Update profile Recent Activity markup to prioritize item.title/item.description.
  5. Notifications & toasts

    • Inspect toast component and toastActions to ensure variants map to distinct DaisyUI classes.
    • Adjust handleNotification to use appropriate variants per event type.
  6. Game lobby & /chat debugging

    • Use browser devtools (network + console) and logs from /api/chat/room to see exact errors.
    • Fix any room-name/session issues; ensure ensureGuestSession and assertRoomName are aligned.
    • If time permits, consider unifying /chat and social socket usage for better UX.

5. How to Work Efficiently

  • Always cross-check with HEAD when editing social.ts. It’s central and easy to break; use git show or git diff to ensure structure stays sane.
  • Lean on existing helpers:
    • renderChatContent for any view that might receive object-shaped Nakama content.
    • normalizeChatContent for store-level normalization.
    • /api/social/activity for activity; don’t reinvent it in profile.
  • Respect Svelte 5 runes:
    • State: $state.
    • Derived state: $derived.
    • Effects: $effect.
    • Use standard HTML onclick etc., not on:click.

If you follow this map, you’ll quickly get to a point where:

  • Social widget channel list previews are accurate.
  • Avatars/names are consistent everywhere.
  • Profile and Social Hub stay in lockstep.
  • Activity feed and notifications actually tell the user what’s happening.

🟡 NEW MEDIUM ISSUES

[∙] I15-I19: Game Containment Tech Debt - DEFERRED 📅

Status: DEFERRED - Architecture improvements for future sprint
Summary:

  • I15: Hardcoded platform URLs → Use FundayBridge
  • I16: Direct Nakama imports → Use window.nakama
  • I17: Platform store imports → Use FundayBridge state
  • I18: Platform component imports → Bundle in games
  • I19: Path escapes (../) → Use aliases Note: Games work currently; this is cleanup for maintainability

[x] I20: Stale IP References - FIXED ✅

Status: FIXED - SDK uses window.location.hostname as primary
Note: 10.43.183.1 refs don’t affect production (hostname used first)


🟢 LOW / TECH DEBT

[∙] I21: Legacy Postgres - DEFERRED 📅

Status: DEFERRED - Nakama correctly uses postgresql namespace
Note: Legacy DB exists but unused; delete after verification


[x] I22: nakama.funday.gg References - FIXED ✅

Status: FIXED - Critical files use funday.gg
Note: Non-critical test/script files remain; Option B implemented


[x] I23: Namespace Rule - VERIFIED ✅

Status: VERIFIED - nakama namespace does NOT exist
Rule: All resources in funday-platform namespace only


📝 NOTES

  • Frontend runs as systemd service, NOT K8s pod
  • K8s DNS names (*.svc.cluster.local) don’t resolve from host
  • NodePort 30177 is the reliable way to reach Nakama from host
  • TLS secret funday-tls-cert is the ONLY valid one
  • Database is in postgresql namespace, NOT funday-platform
  • Redis is in redis namespace at redis-master:6379

═══════════════════════════════════════════════════════════════════════════════ ⚠️ PITFALLS TO AVOID ═══════════════════════════════════════════════════════════════════════════════


Task List — Ongoing Cleanup & Verification

Scope: Post–PIMP:UI maintenance: verify claimed work, close gaps, keep platform/registry/docs honest.
Source of truth for game inventory: docs/game-completion-matrix.md (78 dirs; 0 unregistered per 2026-04-15 scan).
Design tokens entry: frontend/src/app.css (@theme + --spacing-* / --space-*).
Reminder: Private repo — no public pushes; user runs E2E/API tests locally to control cost.

Task List

  • 1. Section: Workspace & search hygiene

    • 1.1 Task: Confirm .gitignore / optional .cursorignore exclude heavy non-source trees (e.g. .kube cache under home, large node_modules duplicates) so agents/IDE index funday/ only where needed — triple-check paths so real assets are not ignored. ✅ 2026-04-20: Verified — frontend/.svelte-kit/ (675MB), **/node_modules/, test-results/, games/**/.svelte-kit/, dist/, build/ all excluded. .kube/ is outside project tree. No .cursorignore needed (Cascade uses .gitignore).
    • 1.2 Task: Prune stale root-level artifacts (tmp/, test-results/, stray logs) per team policy; never delete backups/ without explicit approval. ✅ 2026-04-15: 30+ files → obsolete/, 85MB log truncated, 66MB stale build removed.
  • 2. Section: Design tokens — verify adoption (not just presence)

    • 2.1 Task: Audit frontend/src/app.css @theme / CSS variables against DaisyUI 5 + Tailwind 4 usage; list any duplicate or dead --* vars — remove or document one source of truth. ✅ 2026-04-15: 38+ refs, zero dead tokens, all families consumed.
    • 2.2 Task: Sample high-traffic components (frontend/src/lib/components/layout/*, frontend/src/routes/+page.svelte, play route shell) for raw pixel/radius values; migrate to existing tokens or extend @theme once — avoid one-off numbers. ✅ 2026-04-20: Audited all layout/, +page.svelte, play/[id]/. Findings: 1px borders = CSS primitives; 44-48px = WCAG 2.5.8 touch targets (intentional); blur/shadow px = component-specific effects; play route already uses var(--nav-h, 64px) / var(--dock-h, 0px) CSS vars. No actionable raw values to migrate.
  • 3. Section: Inline styles & shell duplication

    • 3.1 Task: Grep style= in frontend/src/routes and frontend/src/lib/components (skip generated); replace user-facing inline styles with utilities + tokens — triple-check visual parity in light/dark. ✅ 2026-04-15: 71 total, ALL dynamic runtime values — 0 replaceable.
    • 3.2 Task: Identify repeated page/shell wrappers; consolidate toward shared patterns (e.g. PageWrapper or layout slots) without breaking route-specific SEO/metadata. ✅ 2026-04-20: Audited all routes. Found 4 existing patterns: root layout (min-h-screen bg-base-100), dev layout (dev chrome), gaming-container utility (games/profile/settings), auth center (min-h-screen flex items-center justify-center). Each page has unique max-width/padding/bg requirements — a generic PageWrapper would over-abstract and break SEO metadata flexibility. Current layering is correct.
  • 4. Section: Perf-UX — regression pass

    • 4.1 Task: Spot-check list/detail/play flows for spinner-vs-skeleton consistency (GameDrawer, games catalog, profile); align with DaisyUI skeleton where loading is structural. ✅ 2026-04-15: GameCardSkeleton + DaisyUI skeleton consistent.
    • 4.2 Task: Review hero/marketing sections for stacked motion; reduce or gate prefers-reduced-motion if not already. ✅ 2026-04-15: Added guards to HeroSpotlight, ThemeSwitcher, ErrorBoundary.
    • 4.3 Task: Audit keyboard handlers on carousels/sliders; ensure focus trap or arrow keys only when the widget is focused — avoid global key theft. ✅ 2026-04-20: Audited HeroSpotlight (role=application + tabindex + scoped onkeydown), GameCarousel (no keyboard), GameDock (button-based), GamePillStrip (tablist), ColorSlider (native range), ColorPalette (guarded by open flag), CommandPalette (Cmd+K standard), InviteDropdown (Escape only). No global key theft — all handlers properly scoped to focused widgets.
  • 5. Section: Game registry & matrix truth

    • 5.1 Task: Re-scan games/* — verified 2026-04-15: 78 dirs, 32 prod + 11 partial + 27 FE-only + 8 scaffold + 0 unregistered. Matrix date updated.
    • 5.2 Task: Triage Unregistered / Incomplete rows: for each — (a) add funday-plugin.json + wire handler, (b) hide from prod catalog, or (c) move to games/_archive / obsolete/ with README note — do not bulk-delete without review. ✅ 2026-04-20: 10/11 partial games have status=development (hidden from catalog). Pipes is available with working index.html. 0 unregistered. No action needed.
    • 5.3 Task: Spot-check Partial games with missing entry HTML (e.g. battle-cards, turtle-cards): document build/embed path or one-line “blocked on X” in matrix Notes. ✅ 2026-04-20: battle-cards and turtle-cards are Production-Ready (not partial). The 10 actual partial games without entry HTML all have status=development, correctly gated from prod catalog.
  • 6. Section: Backend contract sanity

    • 6.1 Task: For any new/changed RPC or match name, verify nakama-modules/index.ts registration matches frontend callers — grep both sides; avoid orphan RPCs. ✅ 2026-04-15: 46 server / 12 frontend — aligned. 1 phantom get_leaderboard (dev-only, benign).
    • 6.2 Task: After Nakama TS changes, run project’s usual bundle/build for nakama-modules (per README.md / scripts) before deploy — triple-check no nkruntime namespace regressions. ✅ 2026-04-20: pnpm build → 0 errors, 0 warnings, 242ms. IIFE unwrapped. index.js 807KB. No nkruntime regressions.
  • 7. Section: QA & tests (user-triggered)

    • 7.1 Task: Run focused Playwright specs touching auth/routing if routes changed: frontend/tests/guest-auth-validation.spec.ts, frontend/tests/redirects.spec.ts, frontend/tests/legacy-redirects.spec.ts — user runs to avoid CI spam.
    • 7.2 Task: If game registry changes, smoke-test /games and /play/[id] for affected IDs — user executes in browser.
  • 8. Section: Documentation handoff

    • 8.1 Task: When a cleanup slice finishes, add one line to CHECKLIST.md or this file under a Changelog subheading (date + what was verified) — keeps audit trail without duplicating full task lists. ✅ 2026-04-20: Changelog maintained throughout session — see entries below.
    • 8.2 Task: Archive superseded cleanup notes to docs/archive/ with a dated filename when this file is reset.

Changelog

  • 2026-04-01 — Created CHECKLIST_CLEANUP.md as sequential maintenance backlog (orthogonal to completed items in CHECKLIST.md).

🎯 Funday Gaming Platform - Comprehensive Task Checklist

✅ COMPLETED: Infrastructure Blocker Resolution (2025-11-10)

Root Cause Analysis

Problem: HTTPS endpoints returning 502 Investigation Path:

  1. ✅ Confirmed local Node.js healthy (http://127.0.0.1:3000 → 200)
  2. ✅ Confirmed Nginx config correct
  3. ✅ Discovered Traefik LoadBalancer hijacking port 443
  4. ✅ Changed Traefik to ClusterIP
  5. ✅ Discovered Agones Allocator still owning port 443
  6. ✅ Changed Agones Allocator to ClusterIP
  7. ✅ Fixed Nginx buffer sizes for large headers

Solution Applied:

# Patch K8s services
sudo kubectl patch svc traefik -n kube-system -p '{"spec":{"type":"ClusterIP"}}'
sudo kubectl patch svc agones-allocator -n agones-system -p '{"spec":{"type":"ClusterIP"}}'
 
# Update Nginx config with larger buffers
proxy_buffer_size 16k;
proxy_buffers 8 16k;
proxy_busy_buffers_size 32k;

Result: ✅ HTTPS fully operational with Let’s Encrypt certificate

🎮 CONNECT4: Critical Bugs (From Latest Testing)

🔴 P0: Duplicate Presence Bug

  • C4-DUP-1: Same user appears 2x in match presences

    • Evidence: user_id: 75510403... with session_id: 210c2a11... AND 21203078...
    • Root Cause: Host socket joins match + game iframe socket joins again
    • Test: Check Nakama console → Match → Presences count
    • Fix: Prevent double socket.joinMatch() in games/connect4/index.html
  • C4-DUP-2: 4 total presences for 2-player game

    • Evidence: Match shows 4 presences (2 per player)
    • Impact: Game logic may think 4 players = wrong turn assignment
    • File: /games/connect4/index.html ~L810-830

🔴 P0: Off-By-One Column Bug

  • C4-COL-1: Clicking column N drops chip in column N+1
    • Symptom: “Chip drops in field to the right of clicked”
    • Root Cause: Column index calculation error in click handler
    • File: /games/connect4/Connect4Game.js or index.html
    • Test: Click leftmost column, verify chip drops there (not col 2)

🟠 P1: Game State Issues

  • C4-STATE-1: Yellow circle appears top-left on game start

    • Symptom: “Strange yellow circle filled when game starts”
    • Likely: Board initialization or render bug

    • Symptom: Stale game state persists
    • Fix: Clear state on match leave/rejoin
  • C4-STATE-3: Matches never close properly

    • Symptom: "open": false in label but match stays listed
    • Check: connect4_match.lua match_terminate logic

🟠 P1: Chat in Match

  • C4-CHAT-1: Match chat shows “Chat not connected”
    • Root Cause: Channel type mismatch (using match: prefix, need type 2)
    • File: GameDrawer.svelte ~L363-420
  • C4-CHAT-2: “Failed to load chat history” error
    • Test: Check browser console for exact error
    • Verify: Channel name format game:connect4:{matchId}

    • Use: normalizeChatContent() + friends enrichment
  • SOC-AVA-2: handleIncomingMessage enrichment incomplete

    • Required: Lookup from friends store first, fallback to message fields
    • File: social.ts ~L588-618
  • SOC-AVA-3: /api/chat/room enrichment not used by GameDrawer

📋 Task List

Section 1: Build Errors (FIRST)

  • 1.1 GameDock.svelte: Fix deprecated <svelte:component>
    • Svelte 5 runes: use <Icon class="w-4 h-4" /> directly (components are dynamic by default)

Section 2: Board Indexing (CRITICAL)

  • 2.1 connect4_match.lua: Fix board array indexing ✅

    • Added json_encode_array() for proper 0-indexed JSON arrays
    • broadcastState now converts to 0-indexed before sending
  • 2.2 connect4/index.html: Fix draw detection ✅

    • Changed st.winner === null to st.winner === false for draw

Section 3: Match Lifecycle

  • 3.1 connect4_match.lua: Terminate match when empty ✅

    • match_leave returns nil when 0 players
    • Also terminates when game over + player leaves
  • 3.2 connect4_match.lua: Close finished matches ✅

    • Match closes when winner set and player count < 2

Section 4: Chat System

  • 4.1 GameDrawer.svelte: Set matchId before ingame mode ✅

    • lobbyStateActions.set({ matchId }) before setMode("ingame")
    • Chat now connects to match-specific channel
  • 4.2 GameDrawer.svelte: Fix chat reconnection flow

    • When “Chat & Logs” is clicked, properly reinitialize chat

Section 5: State Management

  • 5.1 connect4/index.html: Reset state on re-entry ✅

    • Added board, current, over, lastError reset before join
  • 5.2 connect4/index.html: Winner detection fix ✅

    • Fixed condition to check winner !== undefined && winner !== null

Section 6: Activity Tracking

  • 6.1 nakama-modules/index.ts: Add afterMatchComplete hook

    • Write game result to storage
    • Increment game count for user
    • Update playtime stats
    • File: /nakama-modules/index.ts
  • 6.2 Profile display: Verify activity feed reads storage

    • Check /profile route fetches user activity
    • File: /frontend/src/routes/profile/+page.svelte

Section 7: Duplicate Presences Fix

  • 7.1 GameDrawer.svelte: Remove host’s joinMatch call ✅

    • Host no longer calls socket.joinMatch()
    • Only GAME CLIENT joins the match (prevents 4→2 presences)
    • Host just injects session and sends join-match: action
  • 7.2 GameDrawer.svelte: Remove redundant onmatchdata ✅

    • Host doesn’t subscribe to match data (game handles it directly)

Section 8: Chat Channel Fix

  • 8.1 GameDrawer.svelte: Simplify channel selection ✅
    • Use match channel when matchId exists (no phase check)
    • Channel name: game:connect4:{matchId} for matches

Section 9: Testing & Verification

  • 9.1 Test match creation flow ✅ Match created successfully
  • 9.2 Test 2-player join - verify only 2 presences now
  • 9.3 Verify chat uses match-specific channel
  • 9.4 Verify column clicks drop in correct position ✅ Col 4 → Col 4
  • 9.5 Verify match closes after both leave
  • 9.6 Take screenshot proof ✅ Saved

  • Nakama match handler returns nil from match_leave to terminate match
  • Svelte 5 uses <svelte:component> for dynamic components, @render for snippets only

Frontend Revamp Checklist — Unified Game App Shell (Option A)

Task List

  • 1. Section: App Shell and Routing

    • 1.1 Task: Create route server loader for gameplay — frontend/src/routes/play/[id]/+page.server.ts (resolve plugin via lib/server/plugins.ts; determine integrationType; compute playUrl; allocate Agones server for dedicated-server; return props). Reminder: validate inputs; error handling.
    • 1.2 Task: Create gameplay page — frontend/src/routes/play/[id]/+page.svelte (host persistent Navbar, GameViewport, and GameDock; bind to gameContext store). Reminder: triple-check SSR/hydration.
    • 1.3 Task: Add Navbar HUD integration — modify frontend/src/lib/components/layout/Navbar.svelte (or routes/+layout.svelte) to render a right-side HUD region fed by gameContext. Reminder: avoid blocking main thread; debounce updates.
    • 1.4 Task: Ensure deep-linking to /play/[id] works from library and details pages (no modal overlay). Reminder: consistent history behavior.

    • 9.2 Task: Emit Bridge events (game:ready, funday:nav:set, funday:analytics-event, funday:score-submitted). Reminder: type-safe payloads. (Done: networked-snake-multiplayer, snake-casual)
    • 9.3 Task: Expose native Svelte component entry for integrationType=‘svelte-component’. Reminder: export default component. (Deferred: Phase 3 - documented as TODO in GameViewport.svelte:172)
  • 10. Section: Testing & QA (Automated tests complete; manual QA deferred)

    • 10.1 Task: Cross-browser/mobile check for zero double scrollbars; correct viewport height with device UI. Reminder: iOS notch safe area. (Requires manual QA on physical devices)
    • 10.2 Task: Reactive theme/locale/session end-to-end tests (toggle while playing; no reload). Reminder: latency <100ms to HUD.
    • 10.3 Task: Bridge handshake and message security unit tests (origin checks, invalid payloads). Reminder: property-based tests.
    • 10.4 Task: Security tests for CSP/sandbox/proxy allowlist; attempt framing from disallowed origins (should fail). Reminder: logs sanitized.
    • 10.5 Task: Performance tests (fps stability, input latency, minimal HUD impact; lazy-load verification). Reminder: CPU throttling runs. (Requires Lighthouse/WebPageTest tooling setup)
  • 11. Section: Documentation

    • 11.1 Task: Write FundayBridge v1 spec — docs/BRIDGE_V1.md (events, payloads, lifecycle, examples). Reminder: include SDK usage.
    • 11.2 Task: Write Plugin Embed Guide — docs/PLUGIN_EMBED_GUIDE.md (embed=1, layoutless, event emissions). Reminder: screenshots.
    • 11.3 Task: App Shell Guide — docs/APP_SHELL.md (route structure, HUD/Dock patterns, CSS vars, scroll policy). Reminder: maintenance notes.
  • 12. Section: Rollout & Cleanup

    • 12.1 Task: Migrate each existing internal game to embed mode and Bridge v1; checklist per game. Reminder: track in docs/PLUGIN_MIGRATION.md. (Completed: 4 plugins migrated, tracked in PLUGIN_MIGRATION.md)
    • 12.2 Task: Deprecate gameplay modal; delete or isolate legacy paths (GameModal.svelte) used only for non-game dialogs. Reminder: code search for openModal calls. (Done: GameModal excluded from /play/* routes in +layout.svelte; no modalActions.open calls found in codebase)
    • 12.3 Task: Update CI checks/lints for new files and stricter type coverage. Reminder: fail on any TODO left in bridge.

Notes & Reminders

  • Triple-check SSR/hydration impacts; avoid layout shift.
  • Keep guest-first UX intact; no auth prompts during route transitions.
  • Prefer minimal privileges in sandbox; tighten for external sources.
  • Ensure all origin checks are exact strings; no regex wildcards.
  • Keep code small and readable (JS/TS Quality rules); early returns, strict types, no unnecessary refactors outside scope.
  • Document all public contracts (Bridge, embed) clearly for future plugins.

Status: Phase 1 ✅ Complete | Phase 2 🔄 In Progress Time Invested: ~10 minutes Issues Resolved: 3 critical Remaining Priority: Traffic routing + game verification


🏰 Catan: The Master Blueprint

The following is the definitive, re-architected Master Checklist. It transforms the previous list into a strategic execution roadmap, prioritizing architectural stability (Phase 1) before complexity (Phase 3), ensuring the “Kernel + Extension” pattern is strictly enforced.

Mission: Forge a production-grade, multi-expansion Catan engine. Stack: Svelte 5 (Runes) · Nakama · TypeScript · Tailwind 4 Architecture: Kernel (State/Net) + Extensions (Rules) + Manifests (Data)


🔴 Phase 1: The “Real” Engine Startup (Architecture)

Objective: Eliminate hacks. Establish a unified, deterministic startup flow for both Solo and Multiplayer.

  • 1.1 Fix Entry Point (App.svelte)
    • Remove setTimeout auto-start hack.
    • Bind game.state.started strictly to setupController completion or START_GAME opcode.
    • Ensure initializeMap() only runs once via $effect with tracking.
  • 1.2 Unify Solo/Multiplayer Flow (Lobby.svelte)
    • Wire “Play Solo” button to nakamaManager.setSoloMode(true)setupController.initSetup().
    • Ensure nakamaManager.sendMatchData returns early (no-op) in Solo Mode without errors.
    • Verify SetupController advances state locally in Solo Mode (Optimistic UI).
  • 1.3 The Setup State Machine (SetupController.ts)
    • Implement “Snake Draft” logic (1-2-3-4 → 4-3-2-1).
    • Enforce: Resources granted only on 2nd settlement placement.
    • UI: SetupPhase.svelte must show explicit “Waiting for X” or “Your Turn” states.

🟡 Phase 2: World Generation Integrity (The Bible §2)

Objective: Mathematical perfection of the board layout. No illegal maps.

  • 2.1 Red Number Constraint (MapGenerator.ts)
    • Critical: Implement validateRedNumberPlacement(): No 6 touching 6, 8 touching 8, or 6 touching 8.
    • Implement fixRedNumberViolations(): Smart swapping algorithm (not just random shuffle) to resolve conflicts.
    • Test: Generate 100 maps, assert 0 violations.
  • 2.2 Resource Balance
    • Verify exact tile counts: 4 Wood, 4 Sheep, 4 Wheat, 3 Brick, 3 Ore, 1 Desert.
    • Verify exact port counts: 4 Generic (3:1), 1 of each Specific (2:1).
    • Ensure Desert never receives a number token.

🟢 Phase 3: The Core Rules Engine (The Bible §4-9)

Objective: Bulletproof turn logic and rule enforcement.

  • 3.1 Turn Phase State Machine (GameController.ts)
    • Refactor nextPhase() to strictly follow: ROLLTRADE/BUILD (Interleaved) → END.
    • Inject ship_move phase dynamically only if Seafarers extension is active.
  • 3.2 Development Card Physics (DevCardController.ts)
    • Enforce: Cannot play card bought this turn (check card.boughtThisTurn).
    • Exception: Allow Victory Point cards to be revealed immediately if they trigger a win.
    • Enforce: Max 1 Knight/Progress card per turn.
  • 3.3 The Robber Protocol (RobberController.ts)
    • Trigger: On Roll 7, check hand size > 7 for all players.
    • Flow: Pause game → DISCARD Phase (UI blocks until all discard) → MOVE_ROBBERSTEAL.
    • Logic: Ensure Robber must move to a new hex (cannot stay).

🔵 Phase 4: Victory & Achievements (The Bible §10-12)

Objective: Dynamic scoring and win condition tracking.

  • 4.1 Longest Road (DFS)
    • Implement DFS in BaseExtension to count longest continuous path.
    • Rule: Opponent settlements break the road.
    • Seafarers: Hook onCalculateLongestRoute to include Ships.
  • 4.2 Largest Army
    • Count played Knights only.
    • Logic: Must exceed current holder to steal the card.
  • 4.3 Victory Check
    • Sum: Public VP + Achievement VP + Private VP (Hand).
    • Trigger: Run check after every build/buy action.

🎨 Phase 5: UI/UX “Juice” (Svelte 5)

Objective: Modern, responsive, and delightful interaction.

  • 5.1 Responsive Layout (App.svelte)
    • Remove magic pixels (w-[800px]). Use CSS Grid/Flex regions (Board, HUD, Controls).
    • Ensure HUD stays pinned to bottom on mobile.
  • 5.2 Interaction Feedback
    • Ghost Buildings: Render semi-transparent Settlement/City on vertex hover during build mode.
    • Toasts: Use toasts.svelte.ts for all errors (“Not enough resources”, “Blocked”).
    • Animations: Resource cards “fly” from hex to HUD on harvest.

🛡️ Phase 6: Code Quality & Infrastructure

Objective: Maintainability and type safety.

  • 6.1 Strict Typing
    • Remove all any casts in Controllers.
    • Convert Resource and Terrain to strict Union Types (no strings).
  • 6.2 Network Resilience
    • Handle STATE_SYNC to fully restore extensionState (Seafarers fog, C&K progress).
    • Add reconnection toast on socket close.

    • Verify: 14 Knight, 2 Road Building, 2 Year of Plenty, 2 Monopoly, 5 VP
  • Initialize player inventories: 0 resources, 0 dev cards
  • Initialize player building supplies: 15 roads, 5 settlements, 4 cities
  • Place robber on desert hex

3.2 Starting Player Determination

  • Each player rolls 2d6
  • Highest sum starts
  • Ties: re-roll among tied players only
  • Store turn order (clockwise from starter)

3.3 Initial Placement Phase

Snake Draft Order (n players)

  • Round 1: Player 1 → 2 → … → n (clockwise)
  • Round 2: Player n → n-1 → … → 1 (reverse)

Placement Actions

  • Each placement: 1 settlement + 1 adjacent road
  • Validate Distance Rule before settlement placement
  • Validate road connects to just-placed settlement
  • RULE: Both roads cannot extend from same settlement

Starting Resources

  • After ALL placements complete
  • Each player receives resources from 2nd settlement only
  • 1 resource per adjacent terrain type (not desert)
  • Deduct from bank

3.4 Distance Rule Validation

isValidSettlementPlacement(intersection):
  if intersection.building != null: return false
  for adjacent in intersection.adjacentIntersections:
    if adjacent.building != null: return false
  return true

4. STATE MACHINE & TURN FLOW

4.1 Phase Transitions

SETUP_PLACEMENT_ROUND_1
  → (all placed) → SETUP_PLACEMENT_ROUND_2

SETUP_PLACEMENT_ROUND_2
  → (all placed) → distribute starting resources → PRE_ROLL

PRE_ROLL
  → (player rolls) → ROLL_DICE
  → (player plays dev card) → PRE_ROLL (mark devCardPlayedThisTurn)

ROLL_DICE
  → (roll != 7) → distribute resources → TRADE_BUILD
  → (roll == 7) → ROBBER_DISCARD

ROBBER_DISCARD
  → (all discards resolved) → ROBBER_PLACE

ROBBER_PLACE
  → (robber placed) → ROBBER_STEAL

ROBBER_STEAL
  → (steal resolved) → TRADE_BUILD

TRADE_BUILD
  → (end turn action) → check victory → next player PRE_ROLL
  → (10+ VP) → GAME_OVER

4.2 Turn Actions

Pre-Roll Actions

  • Play development card (if not bought this turn)
  • Roll dice (mandatory, transitions phase)

Trade/Build Actions (interchangeable order)

  • Domestic trade
  • Maritime trade
  • Build road
  • Build settlement
  • Upgrade to city
  • Buy development card
  • Play development card (if not yet played this turn)
  • End turn

4.3 Action Validation

  • All actions validate against current phase
  • All actions validate player has required resources
  • All actions validate building supply available
  • All actions validate placement rules

4.4 Turn Bookkeeping

  • Reset devCardPlayedThisTurn at turn start
  • Clear devCardsBoughtThisTurn at turn start
  • Clear diceRoll at turn start
  • Increment turnNumber
  • Advance currentPlayerIndex (mod player count)

5. DICE SYSTEM

5.1 Dice Roll Implementation

  • Roll 2 independent d6 (1-6 each)
  • Sum for production number (2-12)
  • Store individual dice values (for display/logging)
  • Use cryptographically fair RNG for fairness

5.2 Probability Reference

SumProbabilityCombinations
21/36 (2.78%)1
32/36 (5.56%)2
43/36 (8.33%)3
54/36 (11.11%)4
65/36 (13.89%)5
76/36 (16.67%)6
85/36 (13.89%)5
94/36 (11.11%)4
103/36 (8.33%)3
112/36 (5.56%)2
121/36 (2.78%)1

5.3 Dot Count Mapping

  • Implement: getDotCount(number) → int
  • Formula: dots = 6 - abs(7 - number)
  • Used for UI display and AI evaluation

6. RESOURCE SYSTEM

6.1 Resource Production

produceResources(diceSum):
  if diceSum == 7: return  // handled by robber

  productionMap = Map<PlayerId, Map<ResourceType, int>>

  for hex in board.hexes:
    if hex.numberToken != diceSum: continue
    if hex.hasRobber: continue

    resource = hex.terrain.producesResource()
    if resource == null: continue  // desert

    for intersection in hex.adjacentIntersections:
      if intersection.building == null: continue

      player = intersection.owner
      amount = 1 if intersection.building == SETTLEMENT else 2
      productionMap[player][resource] += amount

  // Check for scarcity
  for resource in ResourceType:
    totalNeeded = sum(productionMap[*][resource])
    available = bank[resource]

    if totalNeeded > available:
      playerCount = count(p where productionMap[p][resource] > 0)
      if playerCount > 1:
        // Multiple players, none receive
        for player in players:
          productionMap[player][resource] = 0
      else:
        // Single player receives all available
        for player in players:
          productionMap[player][resource] = min(productionMap[player][resource], available)

  // Distribute
  for player, resources in productionMap:
    for resource, amount in resources:
      player.resources[resource] += amount
      bank[resource] -= amount

6.2 Resource Scarcity Rules

  • Track bank quantities (19 each initially)
  • If multiple players should receive but bank insufficient: no one receives
  • If single player should receive but bank insufficient: receive all available
  • Log scarcity events

6.3 Bank Operations

  • bankHas(resource, amount) → bool
  • takeFromBank(resource, amount) — validate first
  • returnToBank(resource, amount)
  • bankTotal(resource) → int

7. TRADING SYSTEM

7.1 Domestic Trade

Validation Rules

  • Only active player can initiate/participate
  • Both parties must give ≥1 card
  • Cannot trade 0 cards for something (no gifts)
  • Cannot trade identical resources (e.g., 2 wool for 1 wool)
  • Development cards cannot be traded
  • Non-active players cannot trade with each other

Implementation

validateDomesticTrade(offer, request, fromPlayer, toPlayer):
  if currentPlayer != fromPlayer AND currentPlayer != toPlayer:
    return false  // active player must be involved
  if offer.isEmpty() OR request.isEmpty():
    return false  // no gifts
  if offer.keys().intersect(request.keys()).notEmpty():
    return false  // no same-resource trades
  if not fromPlayer.hasResources(offer):
    return false
  if not toPlayer.hasResources(request):
    return false
  return true

7.2 Maritime Trade

Base Rate (Always Available)

  • 4:1 — trade 4 identical resources for 1 any
  • No harbor required
  • Available to all players on their turn

Harbor Rates

  • 3:1 Generic — requires settlement/city at generic harbor
  • 2:1 Specific — requires settlement/city at matching resource harbor
  • Better rates do NOT replace worse (can still 4:1 if desired)

Implementation

getMaritimeTradeRates(player):
  rates = {default: 4}

  for intersection in player.buildings:
    harbor = intersection.harbor
    if harbor == GENERIC_3_1:
      rates[default] = min(rates[default], 3)
    elif harbor == LUMBER_2_1:
      rates[LUMBER] = 2
    // ... etc for each specific harbor

  return rates

validateMaritimeTrade(player, giveResource, giveAmount, getResource):
  if currentPlayer != player:
    return false  // only on your turn
  rates = getMaritimeTradeRates(player)
  requiredAmount = rates[giveResource] ?? rates[default]
  if giveAmount != requiredAmount:
    return false
  if not player.hasResources({giveResource: giveAmount}):
    return false
  if not bankHas(getResource, 1):
    return false
  return true

7.3 Trade Timing

  • Domestic trade: only during active player’s TRADE_BUILD phase
  • Maritime trade: only during YOUR TRADE_BUILD phase

9. DEVELOPMENT CARDS

9.1 Deck Initialization

initializeDevelopmentDeck():

  deck.addAll([KNIGHT] * 14)
  deck.addAll([ROAD_BUILDING] * 2)
  deck.addAll([YEAR_OF_PLENTY] * 2)
  deck.addAll([MONOPOLY] * 2)
  deck.addAll([VICTORY_POINT] * 5)
  shuffle(deck)
  return deck

9.2 Play Timing Rules

  • Max 1 Knight/Progress card per turn
  • Can play before OR after rolling
  • CANNOT play card bought this turn
  • EXCEPTION: VP cards can be revealed immediately to win
  • VP cards are never “played” — just revealed when winning
  • Once dev card played, cannot play another this turn
canPlayDevelopmentCard(player, card):
  if card not in player.developmentCards: return false
  if card in player.devCardsBoughtThisTurn:
    if card.type != VICTORY_POINT: return false
    // VP cards can only be revealed if they make you win
  if card.type in [KNIGHT, ROAD_BUILDING, YEAR_OF_PLENTY, MONOPOLY]:
    if player.devCardPlayedThisTurn: return false
  return true

9.3 Knight Card

playKnight(player, targetHex, stealFromPlayer):
  // Move robber
  if targetHex == currentRobberHex: return error("must move robber")
  board.robberHexId = targetHex

  // Steal
  if stealFromPlayer != null:
    if not hasAdjacentBuilding(stealFromPlayer, targetHex):
      return error("invalid steal target")
    stolenResource = randomCard(stealFromPlayer.resources)
    if stolenResource != null:
      stealFromPlayer.resources[stolenResource] -= 1
      player.resources[stolenResource] += 1

  // Track knight
  player.playedKnights += 1
  player.developmentCards.remove(KNIGHT)
  player.devCardPlayedThisTurn = true

  // Check Largest Army
  updateLargestArmy()

9.4 Road Building Card

playRoadBuilding(player, edge1, edge2):
  roadsToPlace = []

  if edge1 != null AND canBuildRoad(player, edge1):
    roadsToPlace.add(edge1)
  if edge2 != null AND canBuildRoad(player, edge2):
    // Validate edge2 considers edge1 if placed
    roadsToPlace.add(edge2)

  // Place 0, 1, or 2 roads (as many as valid/available)
  for edge in roadsToPlace:
    if player.roadsRemaining > 0:
      edge.road = true
      edge.owner = player
      player.roadsRemaining -= 1

  player.developmentCards.remove(ROAD_BUILDING)
  player.devCardPlayedThisTurn = true

  updateLongestRoad()

9.5 Year of Plenty Card

playYearOfPlenty(player, resource1, resource2):
  // Take up to 2 resources from bank
  taken = 0

  if resource1 != null AND bankHas(resource1, 1):
    player.resources[resource1] += 1
    bank[resource1] -= 1
    taken += 1

  if resource2 != null AND bankHas(resource2, 1):

9.6 Monopoly Card

playMonopoly(player, resourceType):
  totalStolen = 0

  for otherPlayer in players:
    if otherPlayer == player: continue
    amount = otherPlayer.resources[resourceType]
    otherPlayer.resources[resourceType] = 0
    player.resources[resourceType] += amount
    totalStolen += amount

  player.developmentCards.remove(MONOPOLY)
  player.devCardPlayedThisTurn = true

  return totalStolen  // for logging/UI

9.7 Victory Point Cards

  • Worth 1 VP each when held
  • Kept hidden until victory declared
  • Never “played” — just revealed
  • Count toward victory even when hidden
  • Can reveal after game ends (for score comparison)

10. ROBBER MECHANICS

10.1 Trigger: Rolling 7

Step 1: Discard Phase

handleRobberDiscard():
  discardRequirements = {}

  for player in players:
    cardCount = player.totalResourceCards()
    if cardCount > 7:
      discardRequirements[player] = floor(cardCount / 2)

  // Wait for all players to select discards
  // Transition to ROBBER_PLACE when all resolved

Step 2: Robber Placement

placeRobber(player, targetHex):
  if targetHex == currentRobberHex:
    return error("must move to different hex")

  board.hexes[currentRobberHex].hasRobber = false
  board.hexes[targetHex].hasRobber = true
  currentRobberHex = targetHex

  // Determine steal candidates
  candidates = getPlayersWithBuildingsAdjacentTo(targetHex)
  candidates.remove(player)  // can't steal from self

  if candidates.isEmpty():
    // Skip steal phase
    transitionTo(TRADE_BUILD)
  else:
    // Transition to steal selection
    transitionTo(ROBBER_STEAL)

Step 3: Steal

stealResource(thief, victim):
  if victim.totalResourceCards() == 0:
    return  // nothing to steal

  // Random selection
  allCards = victim.getAllResourceCardsAsList()
  stolenCard = randomChoice(allCards)

  victim.resources[stolenCard] -= 1
  thief.resources[stolenCard] += 1

10.2 Trigger: Knight Card

  • Move robber (same rules as rolling 7)
  • Steal from adjacent opponent
  • NO DISCARD PHASE — only 7 triggers discards

10.3 Robber Blocking

isHexBlocked(hex):
  return hex.hasRobber

// In resource production:
if hex.hasRobber: continue  // skip production

10.4 Valid Robber Placements

  • Any terrain hex (including desert)
  • Cannot stay on current hex
  • Can return to desert
  • Can place on own hex (not recommended)

11. SPECIAL ACHIEVEMENTS

11.1 Longest Road

Calculation Algorithm

calculateLongestRoad(player):
  maxLength = 0

  // Try starting from each of player's roads
  for edge in player.roads:
    length = dfs(edge, player, visited={})
    maxLength = max(maxLength, length)

  return maxLength

dfs(edge, player, visited):
  if edge in visited: return 0
  if edge.owner != player: return 0

  visited.add(edge)
  maxFromHere = 1

  for intersection in edge.adjacentIntersections:
    // Check if blocked by opponent settlement/city
    if intersection.owner != null AND intersection.owner != player:
      continue  // blocked, can't continue through here

    for nextEdge in intersection.adjacentEdges:
      if nextEdge != edge AND nextEdge.owner == player:
        length = 1 + dfs(nextEdge, player, visited)
        maxFromHere = max(maxFromHere, length)

  visited.remove(edge)  // backtrack for other paths
  return maxFromHere

Update Rules

updateLongestRoad():
  for player in players:
    player.longestRoadLength = calculateLongestRoad(player)

  // Find new holder
  candidates = [p for p in players if p.longestRoadLength >= 5]

  if candidates.isEmpty():
    // No one qualifies
    longestRoadHolder = null
    longestRoadLength = 0
    return

  maxLength = max(c.longestRoadLength for c in candidates)
  tiedPlayers = [c for c in candidates if c.longestRoadLength == maxLength]

  if longestRoadHolder in tiedPlayers:
    // Current holder retains on tie
    return

  if tiedPlayers.size() == 1:
    // Clear winner
    longestRoadHolder = tiedPlayers[0]
    longestRoadLength = maxLength
  else:
    // Multiple tied, no holder
    longestRoadHolder = null

Breaking Opponent’s Road

  • Building settlement on opponent’s road intersection splits their road
  • Recalculate all players’ longest road
  • Card may change hands or become unclaimed

11.2 Largest Army

Update Rules

updateLargestArmy():
  // Find player with most knights (minimum 3)
  candidates = [p for p in players if p.playedKnights >= 3]

  if candidates.isEmpty():
    return  // no change

  maxKnights = max(c.playedKnights for c in candidates)

  if largestArmyHolder != null:
    if largestArmyHolder.playedKnights >= maxKnights:
      return  // current holder retains on tie

  // Find new holder (must exceed, not just tie)
  for candidate in candidates:
    if candidate.playedKnights == maxKnights:
      if largestArmyHolder == null OR candidate.playedKnights > largestArmyHolder.playedKnights:
        largestArmyHolder = candidate
        break

Rules

  • Minimum 3 knights to qualify
  • Must EXCEED current holder to take (ties don’t transfer)
  • Once played, knights are permanent (never lost)

12. VICTORY CONDITIONS

12.1 Victory Point Calculation

calculateVictoryPoints(player):
  vp = 0

  // Settlements
  vp += player.settlementsOnBoard() * 1

  // Cities
  vp += player.citiesOnBoard() * 2

  // Longest Road
  if longestRoadHolder == player:
    vp += 2

  // Largest Army
  if largestArmyHolder == player:
    vp += 2

  // Victory Point Development Cards
  vp += player.countDevCards(VICTORY_POINT)

  return vp

12.2 Victory Check

checkVictory():
  if phase == GAME_OVER: return

  currentPlayer = players[currentPlayerIndex]
  vp = calculateVictoryPoints(currentPlayer)

  if vp >= 10:
    winner = currentPlayer
    phase = GAME_OVER
    return true

  return false

12.3 Victory Timing Rules

  • Can only win during YOUR turn
  • Reaching 10 VP on opponent’s turn: wait for your turn
  • Reaching 10 VP during your turn: immediate win
  • Game ends automatically (no need to “declare”)
  • If player unknowingly has 10 VP: they’ve still won

12.4 VP Card Revelation

  • VP cards revealed upon winning
  • May reveal after game ends (if another player wins)
  • Hidden VP cards still count toward victory
  • Buying VP card that gives 10+ VP: immediate win (exception to same-turn rule)

  • State transitions validate preconditions
  • Post-conditions checked after each action

14. EDGE CASES

14.1 Resource Scarcity

  • Bank runs out mid-distribution: apply scarcity rules
  • Year of Plenty with insufficient bank: take what’s available
  • Monopoly when target has 0: no error, 0 received

14.2 Development Cards

  • Deck empty: cannot buy more
  • Road Building with 0-1 roads left: place what you can
  • Playing knight before first roll: allowed
  • VP card bought gives 10 VP: immediate win allowed

14.3 Building

14.5 Robber

  • Place on own hex: allowed (but warned)
  • All adjacent players have 0 cards: no steal
  • Place on desert: allowed
  • Stay on same hex: blocked

14.6 Longest Road

  • Circular roads: count full length
  • Road broken by settlement: recalculate both segments
  • Multiple players tied: card unclaimed OR current holder retains
  • 5-length achieved simultaneously: first to build gets it

14.7 Victory

  • 10+ VP not on your turn: wait
  • Tied for longest road at 10 VP: check if card held
  • VP card hidden but puts you at 10: you’ve won

  • Additional hexes: 11 (total 30)
  • Additional number tokens: 28 (letters A-Zc)
  • Additional resources: 25 (5 per type, total 120)

}

Checklist

  • VP cards count even when hidden in hand
  • Settlements = 1 VP each
  • Cities = 2 VP each

  | { phase: "robberDiscard"; pendingDiscards: Map<PlayerId, number> }
  | { phase: "robberPlace" }
  | { phase: "robberSteal"; validTargets: PlayerId[] }
  | { phase: "main" } // trade/build phase
 
  // End
  | { phase: "gameOver"; winner: PlayerId }

Checklist

  • Setup has 2 rounds with reverse order in round 2
  • preRoll allows playing dev card before dice
  • postRoll transitions based on dice result (7 vs other)
  • robberDiscard tracks who still needs to discard
  • robberSteal knows valid steal targets
  • main phase allows interleaved trade/build
  • gameOver stores winner

4.2 Phase Transitions

// state/transitions.ts
 
// PSEUDOCODE: Phase transition logic
/*
setup(round=1) 
  → [all placed] → setup(round=2)
  
setup(round=2)
  → [all placed] → distributeStartingResources() → preRoll
 
preRoll
  → [roll action] → postRoll(dice)
  → [play dev card] → preRoll (mark hasPlayedDevCardThisTurn)
 
postRoll(dice)
  → [sum ≠ 7] → distributeResources(sum) → main
  → [sum = 7] → calculateDiscards() → robberDiscard OR robberPlace
 
robberDiscard
  → [all discarded] → robberPlace
 
robberPlace
  → [placed] → robberSteal OR main (if no valid targets)
 
robberSteal
  → [stolen] → main
 
main
  → [end turn] → checkVictory() → nextPlayer preRoll OR gameOver
  → [10+ VP achieved mid-turn] → gameOver
*/

Checklist

  • Setup round 1: clockwise order
  • Setup round 2: reverse order (snake draft)
  • Starting resources from 2nd settlement only
  • Roll 7: discards happen BEFORE robber placement
  • Roll 7: ALL players check for discard simultaneously
  • Victory check after every state change that could affect VP

4.3 Turn State

// state/TurnState.svelte.ts
export interface TurnState {
  currentPlayerIndex: number
  turnNumber: number
  phase: GamePhase
 
  // Within-turn tracking
  diceRolled: boolean
  diceResult: [number, number] | null
  devCardPlayedThisTurn: boolean
  devCardsBoughtThisTurn: DevCard[]
}

Checklist

  • Reset devCardPlayedThisTurn at turn start
  • Reset devCardsBoughtThisTurn at turn start
  • Clear dice result at turn start
  • Increment turn number at turn start
  • Advance player index (mod player count) at turn end

  8: 5 / 36, // 13.89%
  9: 4 / 36, // 11.11%
  10: 3 / 36, // 8.33%
  11: 2 / 36, // 5.56%
  12: 1 / 36, // 2.78%

  • Only on YOUR turn (cannot maritime trade on opponent’s turn)
  • Bank must have the requested resource
  • Can use harbor same turn you build on it

8.3 Trade Timing

Checklist

  • Domestic trade: main phase only, active player involved
  • Maritime trade: main phase only, your turn only
  • No trading during setup
  • No trading during robber phases
  • No trading during Special Building Phase (5-6 player)

  }
  
  return discards;
}
 
// Examples:
// 7 cards → discard 0 (not > 7)
// 8 cards → discard 4 (floor(8/2))
// 9 cards → discard 4 (floor(9/2))
// 10 cards → discard 5
// 11 cards → discard 5
*/

Checklist

  • Trigger: MORE THAN 7 (> 7, not ≥ 7)
  • 7 cards = safe, 8+ cards = must discard
  • Discard amount: floor(total / 2)
  • ALL players check simultaneously
  • Player chooses which cards to discard
  • Discarded cards return to bank
  • Development cards do NOT count

Step 2: Robber Placement

// PSEUDOCODE: Robber placement validation
/*

*/

Checklist

  • Only steal from players with buildings adjacent to robber’s NEW hex
  • Cannot steal from self
  • If multiple valid targets, thief chooses one
  • Steal is RANDOM (victim holds cards face-down)
  • Cannot look at victim’s hand
  • If victim has 0 cards, nothing stolen
  • If no valid targets, skip stealing

10.2 Robber Blocking

// In resource production:
if (hex.hasRobber) continue // Skip this hex entirely

Checklist

  • Hex with robber produces NOTHING
  • Affects ALL players with adjacent buildings
  • Blocking persists until robber moves again

10.3 Knight Card vs Rolling 7

AspectRolling 7Knight Card
DiscardYES (all players > 7)NO
Move RobberYESYES
StealYESYES
Can do both in one turnN/AYES (after rolling 7)

Checklist

  • Knight does NOT trigger discard
  • Can play knight AFTER rolling 7 (two robber moves in one turn)

Checklist

  • Count longest continuous path (not total roads)
  • Forks don’t add — choose longest branch
  • Circles count — full length of circle road
  • Own settlements/cities do NOT break your road
  • Opponent settlements/cities DO break your road
  • Minimum 5 segments to qualify
  • DFS from each edge, take maximum

Checklist

  • First to reach 5 segments gets card
  • Must EXCEED to take (tie doesn’t transfer)
  • Current holder retains on tie
  • If road broken and no one has 5+, card goes to no one

Checklist

  • Win requires 10+ VP on YOUR turn
  • Reaching 10 VP on opponent’s turn: wait for your turn

🐢 Infinite Turtles — Active Dev Checklist (Living)

Briefing

  • Goal: Ship platform-ready embed at /play/infinite-turtles with Bridge v1 HUD/Dock and server-owned deck integrity.
  • Current: Platform build updated; service restart pending; nested dev plugins supported; docs/plan prepared.
  • Blocking: Frontend service restart required to load new build; turtles lacks BridgeService + deck RPC + locks.

Active Tasks

  • Restart frontend service; verify routes
    • systemctl restart funday-frontend.service
    • Check /play/fungame, /games/assets/infinite-turtles, /play/infinite-turtles
  • Add BridgeService (client)
    • Encapsulate handshake/acks; nav:set/dock:set; analytics events
  • Implement deck RPC suite (Nakama TS)
    • turtle_deck_* save/get/list/delete/set_primary/lock (+ validation, banlist, checksums, rate limits)
    • Validate in matchJoinAttempt (reject invalid decks)
  • Matchmaking + socket robustness
    • Include deckHash/format/region; connectWithRetry + reconnect UX; pause background
  • Performance & assets
    • KTX2/DRACO for heavy assets; dvh/svh viewport; throttle heavy 3D; measure FPS baseline
  • Ship & E2E
    • Publish to games/infinite-turtles/build; verify /games/assets/infinite-turtles
    • Two-tab smoke: queue→match→tick; no console errors

Notes

  • Keep UI pure; only GameAPI may call network.
  • Host owns chrome; game declares HUD/Dock.
  • Guest-first: never block gameplay for auth.
