-# Minimal MVP Plan: P2P Poll App
-
-## Recommendation
-
-Build the MVP with:
-
-- Vanilla JS or TypeScript
-- Vite for local dev/build
-- Yjs for shared state
-- `y-webrtc` for browser-to-browser sync
-- `y-indexeddb` for local persistence/offline recovery
-
-This is the best fit for a small poll app because the data model is tiny, concurrent edits are possible, and Yjs already solves merge/conflict handling while `y-webrtc` gives a direct P2P transport with only signaling infrastructure.
-
-## Why This Stack
-
-### Recommended: Yjs + y-webrtc
-
-- Best balance of simplicity and correctness
-- Clients connect directly over WebRTC
-- No custom conflict-resolution logic needed
-- Easy to add offline persistence
-- Good fit for a single shared document/room
-
-### Not recommended for the first MVP
-
-#### PeerJS
-
-- Very simple transport layer
-- But you must design and maintain your own replication and merge rules
-- Fine for demos with a host-authoritative peer, weaker for true collaborative editing
-
-#### GUN
-
-- Fast to prototype realtime shared state
-- But official tutorials commonly use a GUN peer/relay server for shared data
-- For this app, its data model is less explicit than a CRDT and gives less control over vote semantics
-
-#### Automerge
-
-- Very capable CRDT and local-first model
-- But heavier than needed for a single small poll
-- Better choice if the project is expected to evolve into a richer collaborative app
-
-## MVP Scope
-
-Ship exactly one shared poll per room.
-
-Included:
-
-- Join a poll by opening a shared URL
-- Add a new option
-- Vote for one option
-- Change your vote
-- Realtime updates across peers
-- Local persistence in the browser
-- Basic connection status UI
-
-Excluded:
-
-- User accounts
-- Multiple polls per room
-- Option deletion/editing
-- Authentication/authorization
-- Rich presence
-- Advanced discovery
-- Production-grade TURN/signaling deployment
-
-## MVP UX
-
-Keep the interface intentionally small:
-
-- Poll title at the top
-- Option list with vote counts
-- One button per option to cast vote
-- Small form to add an option
-- Status line showing `connecting`, `connected`, or `offline`
-- Small label showing which option you voted for
-
-Join model:
-
-- Room ID in the URL, e.g. `/?room=poll-demo`
-- Users share the URL manually
-
-Identity model:
-
-- Generate a local `userId` once and store it in `localStorage`
-- Optional local display name, also stored locally
-
-## Shared Data Model
-
-Use a single Yjs document per room.
-
-Suggested structure:
-
-- `poll` as a `Y.Map`
-- `poll.title` as a string
-- `poll.options` as a `Y.Map<optionId, Y.Map>`
-- `poll.votes` as a `Y.Map<userId, optionId>`
-
-Each option record:
-
-- `id`
-- `label`
-- `createdBy`
-- `createdAt`
-
-Important design choice:
-
-Do not store vote counters as mutable shared numbers for the MVP.
-Instead, derive counts from `votes`.
-
-Why:
-
-- A user changing vote becomes a single write: `votes[userId] = optionId`
-- No double-counting logic
-- Concurrent writes are easier to reason about
-- Rendering counts from `votes` is trivial at this scale
-
-## Sync Model
-
-### Networking
-
-- Use `WebrtcProvider(roomId, ydoc)`
-- Start with the default public signaling servers for local development
-- If needed, swap to a self-hosted signaling server later without changing the app model
-
-### Persistence
-
-- Use `IndexeddbPersistence(roomId, ydoc)`
-- This preserves state across reloads and helps when reconnecting after temporary disconnects
-
-### Conflict behavior
-
-- Concurrent option additions merge naturally
-- Concurrent vote changes resolve at the per-user key level
-- Tally is recalculated from the merged vote map
-
-## Suggested Project Structure
-
-```text
-src/
-  main.ts
-  app.ts
-  state.ts
-  sync.ts
-  render.ts
-  identity.ts
-  styles.css
-index.html
-```
-
-Responsibilities:
-
-- `sync.ts`: create Yjs doc, WebRTC provider, IndexedDB provider
-- `state.ts`: shared structures, add option, cast vote, selectors
-- `identity.ts`: local `userId` and optional name
-- `render.ts`: DOM updates
-- `app.ts`: wire events to state and rendering
-
-## Implementation Plan
-
-### Phase 1: App shell
-
-- Create Vite app with vanilla TS or JS
-- Add a minimal single-page UI
-- Parse `room` from the URL
-- Generate and persist `userId`
-
-Success check:
-
-- App loads
-- Room ID appears in UI
-- User can type in the form
-
-### Phase 2: Shared state
-
-- Add Yjs document
-- Create root shared maps
-- Seed default poll title if missing
-- Observe document updates and re-render UI
-
-Success check:
-
-- State exists in one browser tab
-- Refresh keeps local state when IndexedDB is enabled
-
-### Phase 3: P2P sync
-
-- Add `y-webrtc`
-- Join room based on URL room ID
-- Show connection status from provider events
-
-Success check:
-
-- Two browsers on different tabs/devices see the same options
-- New options appear in near real time
-
-### Phase 4: Voting logic
-
-- Implement `castVote(optionId)` as `votes.set(userId, optionId)`
-- Derive tallies from `votes`
-- Highlight the local user’s current vote
-
-Success check:
-
-- Votes update live across peers
-- Changing vote updates counts correctly
-
-### Phase 5: Basic hardening
-
-- Trim/validate option labels
-- Prevent empty options
-- Ignore duplicate labels case-insensitively for MVP
-- Show simple offline/connecting text
-
-Success check:
-
-- Basic misuse does not break the UI
-- Reconnect restores updates
-
-## Minimal API Surface
-
-These functions are enough for the first build:
-
-- `getRoomId(): string`
-- `getUserId(): string`
-- `initSync(roomId): AppSync`
-- `ensurePollInitialized()`
-- `addOption(label: string)`
-- `castVote(optionId: string)`
-- `getViewModel(): PollViewModel`
-- `render(viewModel)`
-
-## Risks And MVP Mitigations
-
-### NAT / WebRTC connectivity
-
-Risk:
-
-- Some peer pairs may fail to connect in restrictive networks
-
-Mitigation:
-
-- Accept this for MVP
-- Keep signaling configurable
-- Add TURN only if testing shows frequent failures
-
-### Small public signaling dependency
-
-Risk:
-
-- Public signaling is fine for demos, not ideal for production
-
-Mitigation:
-
-- Treat it as replaceable infrastructure
-- Self-host later if the prototype is kept
-
-### Duplicate or messy options
-
-Risk:
-
-- Users may add near-duplicate entries
-
-Mitigation:
-
-- Normalize labels
-- Prevent exact duplicates for MVP
-
-### No trust/auth model
-
-Risk:
-
-- Any participant in the room can add options and vote
-
-Mitigation:
-
-- Accept for MVP
-- Frame rooms as small trusted groups
-
-## Estimated MVP Size
-
-For one developer:
-
-- Initial prototype: 0.5 to 1 day
-- Polished MVP with basic resilience: 1 to 2 days
-
-Rough code size:
-
-- 250 to 500 lines plus styles
-
-## Nice Next Steps After MVP
-
-- Copy-link button
-- Participant list / presence
-- Vote limit modes: single-choice or multi-choice
-- Option editing/deletion
-- QR code for room join
-- Self-hosted signaling server
-- PWA packaging for better offline behavior

 # P2P Poll App
 
-Small peer-to-peer polling app built with `Vite`, `TypeScript`, `Yjs`, `y-webrtc`, and `y-indexeddb`.
+A peer-to-peer polling application where users can create polls, add options, and vote in real-time without a central server.
 
 ## Features
 
-- single shared poll per room
+- **Real-time P2P voting** using WebRTC via PeerJS
-- add options collaboratively
+- **Dynamic option management** - add/remove options during polling
-- one vote per user, changeable at any time
+- **Duplicate vote prevention** - one vote per user
-- peer-to-peer sync over WebRTC
+- **Automatic data synchronization** across all connected peers
-- local browser persistence for refresh/reconnect recovery
+- **Local storage persistence** for poll recovery
-- shareable room URL
+- **Responsive design** works on desktop and mobile
+- **No server required** - uses PeerJS free signaling service
 
-## Run locally
+## How to Use
 
-```bash
+1. **Open the app** in your browser (open `index.html`)
-npm install
+2. **First user (Host)**: Leave the Peer ID field empty and click "Connect to Host"
-npm run dev
+3. **Copy your Peer ID** using the "Copy Your Peer ID" button
+4. **Share your Peer ID** with other users (via chat, email, etc.)
+5. **Other users**: Paste the host's Peer ID and click "Connect to Host"
+6. **Create a poll** with question and options
+7. **Vote** by clicking on options (one vote per person)
+8. **Watch results** update in real-time across all devices
+
+## Technical Details
+
+- **P2P Library**: PeerJS (WebRTC-based)
+- **Frontend**: Vanilla JavaScript with modern CSS
+- **Data Sync**: Custom conflict resolution for concurrent operations
+- **Storage**: localStorage for basic persistence
+- **Network**: Full mesh topology where each peer connects to all others
+
+## File Structure
+
+```
+├── index.html              # Main application
+├── css/
+│   └── styles.css          # Application styling
+└── js/
+    ├── app.js              # Main application logic
+    ├── peer-manager.js     # P2P connection handling
+    ├── poll-manager.js     # Poll data and sync logic
+    └── ui-controller.js    # UI interactions
 ```
 
-Open the local URL in two tabs or browsers and use the same `?room=` query string to join the same poll.
+## Browser Support
 
-Example:
+Requires modern browsers with WebRTC support:
+- Chrome 23+
+- Firefox 22+
+- Safari 11+
+- Edge 79+
 
-```text
+## Development
-http://localhost:5173/?room=poll-demo
-```
 
-## Build
+Simply open `index.html` in a browser - no build process required. For testing with multiple peers, open the app in multiple browser tabs or windows.
-
-```bash
-npm run build
-```
-
-## Notes
-
-- The app uses public signaling through `y-webrtc` for MVP simplicity.
-- Poll state is not stored on an application server.
-- WebRTC connectivity can still depend on the network environment of the participating peers.
