-# Plan: Combined P2P Polling App
-
-## Overview
-Merge the three subfolder projects into a single TypeScript + Yjs + Vite application at the repo root, combining the best features from each.
-
-## Technology Choices
-- **Language:** TypeScript (from project 3) with strict mode
-- **CRDT:** Yjs + y-webrtc + y-indexeddb (from projects 1 & 3)
-- **Build:** Vite (shared by all)
-- **Package manager:** npm
-
-## Feature Superset
-From **project 1** (group-efa16e66):
-- Collaborative title editing via Y.Text (real-time character-level sync)
-- Delete options
-- Diff-rendering for poll list (reuse DOM elements)
-- Peer count display via awareness
-- Share section with copy-to-clipboard
-
-From **project 2** (proposal-8835ffc9):
-- Deadline/timer system (2-minute voting window with countdown)
-- Duplicate detection (case-insensitive)
-
-From **project 3** (proposal-88461784):
-- TypeScript types & strict mode
-- Modular architecture (state, sync, render, identity, app layers)
-- IndexedDB persistence (offline support)
-- Online/offline connection tracking
-- Input validation (max lengths, empty checks)
-- HTML escaping for XSS prevention
-- ViewModel pattern for clean render layer
-
-## Data Model (Yjs)
-```
-Y.Doc
-├── poll-meta (Y.Map<string>)
-│   └── title → Y.Text (collaborative editing from project 1)
-├── poll-options (Y.Map<OptionRecord>)
-│   └── [optionId] → { id, label, createdAt, createdBy }
-├── poll-votes (Y.Map<string>)
-│   └── [userId] → optionId (single vote per user)
-└── poll-deadline (Y.Map<any>)
-    └── deadline → number | null (timestamp, from project 2)
-```

-
-## Implementation Steps
-
-### Step 1: Scaffold root project
-- Create `package.json` with dependencies: yjs, y-webrtc, y-indexeddb, vite, typescript
-- Create `tsconfig.json` (strict, ES2022, bundler resolution)
-- Create `index.html` entry point
-- Create `vite.config.ts` if needed
-
-### Step 2: Core layer — identity.ts, state.ts, sync.ts
-- `identity.ts`: port from project 3 (getUserId)
-- `state.ts`: port types from project 3, add deadline types, add ViewModel with deadline/timer info, add vote percentage calculation from project 1
-- `sync.ts`: port from project 3, add Y.Text for title (from project 1), add poll-deadline map, add awareness tracking for peer count (from project 1)
-
-### Step 3: App orchestrator — app.ts, main.ts
-- `app.ts`: port from project 3, add deadline handlers, add delete option handler, wire up all components
-- `main.ts`: minimal entry that calls initApp
-
-### Step 4: Components
-- `PollTitle.ts`: port collaborative Y.Text editing from project 1, add TypeScript types
-- `AddOption.ts`: merge project 1 (UI/animation) + project 2 (duplicate detection) + project 3 (validation)
-- `PollOption.ts`: port from project 1 (vote bar, percentage, delete button), add TypeScript
-- `PollList.ts`: port diff-rendering from project 1, add TypeScript
-- `StatusBar.ts`: merge project 1 (peer count) + project 3 (online/offline status)
-- `ShareSection.ts`: port from project 1, add TypeScript
-- `DeadlineTimer.ts`: new component porting project 2's deadline/countdown logic to Yjs
-
-### Step 5: Styling
-- Merge CSS: use project 1's design tokens and typography as base, incorporate project 3's glassmorphism panel effects, add timer-specific styles from project 2
-
-### Step 6: Cleanup
-- Remove three subfolders (after confirming with user)
-- Update root README.md

 # P2P Poll App
+
+A peer-to-peer polling app built with [Automerge](https://automerge.org/) and Vanilla JS. No backend required — polls sync in real time across browsers using CRDTs and a WebSocket relay.
+
+## Features
+
+- **Add options** — type an option and press Enter or click "Add Option". Duplicate options (case-insensitive) are rejected with an inline error message.
+- **Vote on options** — click the vote button next to any option. You can vote on multiple options, but only once per option.
+- **Toggle votes** — click your vote again to remove it (the button turns green with a checkmark when you've voted).
+- **Live vote counts** — options are sorted by vote count in descending order and update in real time as votes come in from other users.
+- **2-minute countdown timer** — click "Start 2-min Vote" to begin a shared countdown. Voting is open before and during the countdown. Once the timer expires, all vote buttons are disabled.
+- **Shared timer** — the deadline is stored in the Automerge document, so all peers see the same countdown and voting closes simultaneously for everyone.
+- **Copy URL** — click "Copy URL" to copy the poll link to your clipboard. Share it with others to join the same poll.
+- **P2P sync** — all state (options, votes, timer) syncs across browsers in real time with no central server handling your data.
+
+## How it works
+
+### Tech stack
+
+- **[Automerge](https://automerge.org/)** via `@automerge/vanillajs` — a CRDT library that lets multiple clients concurrently edit shared documents and merge changes without conflicts.
+- **BroadcastChannelNetworkAdapter** — syncs between tabs in the same browser instantly via the browser's BroadcastChannel API.
+- **WebSocketClientAdapter** — syncs across different browsers/devices via a WebSocket relay (`wss://sync.automerge.org`). The relay only forwards CRDT messages; it does not store or interpret your data.
+- **IndexedDBStorageAdapter** — persists the document locally so it survives page refreshes.
+- **Vite** — bundles the app with WebAssembly support (required by Automerge).
+
+### Data model
+
+The poll is a single Automerge document with three fields:
+
+```js
+{
+  options: string[],       // list of poll options in insertion order
+  votes: { [option]: number }, // vote count per option
+  deadline: number | null  // Unix timestamp (ms) when voting closes, or null
+}
+```
+
+### URL-based sharing
+
+Each document gets a unique Automerge URL (e.g. `automerge:abc123...`) stored in the page's URL hash. Opening the same URL in any browser loads and syncs the same document. Creating a new poll generates a new document and updates the hash automatically.
+
+### Voting rules
+
+- Voted options are tracked in `localStorage` (keyed by document URL), so they persist across page refreshes but are isolated per browser.
+- One vote per option per user. Votes can be toggled off and back on until the timer expires.
+- The timer (`doc.deadline`) is set once by whoever clicks "Start 2-min Vote" and is shared via the Automerge document, so all peers use the same deadline.
+
+## Running locally
+
+```bash
+pnpm install
+pnpm dev
+```
+
+Open the printed localhost URL. To test cross-browser sync, copy the URL (including the `#automerge:...` hash) and open it in a different browser.
