-# 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
