+# Warpspeed Bounty #3 — Poll Creation & Voting UI — Design
+
+## Architecture Overview
+
+```
+Chat UI
+  └─ Action Menu ("+") ──> PollCreationSheet
+                                │
+                          PollStore.createPoll()
+                                │
+                          Chat Message (InlinePoll)
+                                │
+                    ┌───────────┴───────────┐
+               PollVoting             PollResults
+               (not voted)            (voted)
+                                          │
+                                    ViewVotesSheet
+```
+
+The poll feature integrates directly into the group chat message list. Each poll is rendered as an `InlinePoll` card. Before the current user votes, the card shows `PollVoting` (interactive options). After voting, it swaps to `PollResults` (read-only bars with percentages). A "View Votes" button opens the `ViewVotesSheet` bottom sheet listing every voter grouped by option.
+
+## Component Responsibilities
+
+| Component | Role |
+|---|---|
+| `PollCreationSheet` | Bottom sheet modal — question input, dynamic option list (2–12), single/multi toggle, create action. |
+| `InlinePoll` | Container card in the chat — header badge, question, delegates to `PollVoting` or `PollResults`. |
+| `PollVoting` | Radio buttons (single) or checkboxes (multi) — selection state, submit vote. |
+| `PollResults` | Horizontal result bars, percentages, vote counts, leading-option crown, "View Votes" trigger. |
+| `ViewVotesSheet` | Bottom sheet with `SectionList` — each option is a section, voters listed with avatar + timestamp. |
+
+## Data Flow
+
+1. User taps the "+" action button in chat input → `PollCreationSheet` opens.
+2. User fills in question + options + toggles multi/single → taps "Create Poll".
+3. `PollStore.createPoll()` is called → returns a `Poll` object stored in the MobX store.
+4. A chat message containing the `InlinePoll` component is inserted into the message list.
+5. User taps options → `PollVoting` manages local selection state → "Vote" button calls `PollStore.castVote()`.
+6. `castVote` adds the user's `Vote` record to each selected option's `voters` array and sets `poll.userVote`.
+7. Because `poll.userVote` becomes defined, `InlinePoll` automatically swaps to `PollResults`.
+8. `PollResults` reads option voters via `getResults()` which computes percentages, leading option, etc.
+9. "View Votes" fires a callback that renders `ViewVotesSheet` with the same data, grouped by option.
+
+## State Management (MobX)
+
+`PollStore` is a singleton MobX store with `makeAutoObservable`:
+
+- `polls: Map<string, Poll>` — observable map of all polls in the session.
+- `createPoll(data, createdBy)` — generates IDs, builds `PollOption[]`, stores poll.
+- `castVote(pollId, optionIds, userId, username)` — validates, pushes `Vote` objects, sets `userVote`.
+- `getResults(pollId)` — derived array of `PollResult` with percentages.
+- `hasUserVoted(pollId)` — convenience getter.
+
+Votes are **immutable** once cast (one user = one vote). Multi-choice allows selecting multiple options in a single submission.
+
+## Styling Approach
+
+- Dark theme (matching Warpspeed's iOS aesthetic): `#1C1C1E` surfaces, `#2C2C2E` inputs, `#FFFFFF` text, `#8E8E93` secondary.
+- Accent: `#0A84FF` (iOS blue) for selected states, buttons.
+- 12-color palette (`POLL_COLORS`) for result bars — distinct enough to differentiate options.
+- Bottom sheets use `borderTopLeftRadius: 16` / `borderTopRightRadius: 16` with a drag handle indicator.
+- All touch targets are ≥44px height for accessibility.
+- `SectionList` in `ViewVotesSheet` groups voters by option with a colored dot per section header.
+
+## Edge Cases
+
+- **Multi-choice toggle**: `PollCreationSheet` shows `Switch`; `PollVoting` renders checkboxes when true.
+- **Empty poll vote**: "View Votes" shows "No votes yet" empty state.
+- **255 char limit**: enforced on each option input; question limit of 500 chars.
+- **Min 2 / Max 12 options**: creation sheet disables add/remove at boundaries.
+- **Leading option**: `PollResults` shows a crown emoji next to the leading option(s); ties are handled (multiple leaders).
+- **User's own vote**: highlighted with blue text + a blue dot indicator on the result bar.
+- **Single choice re-selection**: tapping the same radio button deselects it (allows un-selection before submit).
+
+## Future Considerations
+
+- API integration: replace MobX store with socket events, persist polls server-side.
+- Poll expiry: add `endsAt` timestamp + auto-close + "Poll closed" state.
+- Edit poll: allow creator to add options before voting starts.
+- Anonymous polls: hide usernames in results.
+- Reactions: add emoji reactions on poll cards.

+# Warpspeed Bounty #3 — Group Chat Poll Creation & Voting UI
+
+**Bounty Amount:** $440  
+**Category:** React Native / TypeScript / MobX  
+**Status:** ✅ Reference Implementation
+
+## Overview
+
+A complete, production-ready reference implementation of the Warpspeed Group Chat Poll Creation & Voting feature. Users can create polls directly from the chat input action menu, vote on polls, view real-time results with percentage bars, and inspect voter details per option in a bottom sheet.
+
+## Files
+
+| File | Purpose |
+|---|---|
+| `types.ts` | All TypeScript interfaces (`Poll`, `PollOption`, `Vote`, `PollResult`) and constants |
+| `state/pollStore.ts` | MobX store with `createPoll`, `castVote`, `getResults` |
+| `components/PollCreationSheet.tsx` | Bottom sheet for creating polls (question + 2–12 options, single/multi) |
+| `components/InlinePoll.tsx` | Poll card rendered inline in chat messages |
+| `components/PollVoting.tsx` | Interactive voting (radio / checkbox select, submit) |
+| `components/PollResults.tsx` | Result bars with percentages, leading option, vote counts |
+| `components/ViewVotesSheet.tsx` | Bottom sheet listing voters grouped by option |
+| `DESIGN.md` | Architecture overview, component tree, data flow, styling, edge cases |
+
+## Usage
+
+```tsx
+import { pollStore } from './state/pollStore';
+import { InlinePoll } from './components/InlinePoll';
+import { PollCreationSheet } from './components/PollCreationSheet';
+
+// 1. Show creation sheet
+<PollCreationSheet
+  visible={showCreation}
+  onClose={() => setShowCreation(false)}
+  onCreate={(data) => {
+    const poll = pollStore.createPoll(data, currentUserId);
+    appendMessage({ type: 'poll', pollId: poll.id });
+  }}
+/>
+
+// 2. Render inline poll in chat
+<InlinePoll
+  poll={pollStore.getPoll(pollId)!}
+  currentUserId={currentUserId}
+  currentUsername={currentUsername}
+  onVote={(pollId, optionIds) =>
+    pollStore.castVote(pollId, optionIds, currentUserId, currentUsername)
+  }
+  onViewVotes={(pollId) => setViewingPollId(pollId)}
+/>
+
+// 3. View votes bottom sheet
+<ViewVotesSheet
+  visible={viewingPollId !== null}
+  poll={viewingPollId ? pollStore.getPoll(viewingPollId) : null}
+  onClose={() => setViewingPollId(null)}
+/>
+```
+
+## Key Features
+
+- **Poll Creation**: Bottom sheet with question + 2–12 options (255 char limit each), single/multi-choice toggle
+- **Inline Poll**: Chat-native card with question, options, voting controls
+- **Direct Voting**: Radio buttons (single) / checkboxes (multi), submit vote
+- **Real-Time Results**: Animated bars, percentages, vote counts, leading-option crown
+- **View Votes**: SectionList grouped by option with voter avatars and timestamps
+- **MobX State Management**: Observable store with auto-computed results
+- **Dark Theme**: iOS-style dark mode design system
+
+## Dependencies
+
+- `react-native` (≥0.72)
+- `mobx` (≥6.10) + `mobx-react-lite`
+- TypeScript (≥5.0)
+
+No third-party UI libraries required — all components use React Native core primitives.
