# Issue #1 Fixes — Design Spec
**Goal:** Address all items in Gitea issue #1 — rework predictions to use full ESC entries with tap-to-assign UI, remove Dish of the Nation, rename acts, add player submission indicators, and make lobby code copyable.
**Source:** https://git.felixfoertsch.de/felixfoertsch/esc/issues/1
---
## 1. Entry Data Model
Replace the current country-only lineup with full ESC entries:
```ts
type Entry = {
country: { code: string; name: string; flag: string }
artist: string
song: string
}
type Lineup = {
year: number
entries: Entry[]
}
```
The data file changes from `esc-2026.json` to `esc-2025.json` using real ESC 2025 entries for testing. Each entry includes the flag emoji in the data file.
Display format everywhere: `🇩🇪 Abor — Süden`
## 2. Prediction Model
Replace the current `{ predictedWinner, top3[], nulPointsPick }` with 4 ordered picks:
```ts
type Prediction = {
playerId: string
first: string // country code
second: string // country code
third: string // country code
last: string // country code
}
```
**Validation:** All 4 picks must be distinct country codes from the lineup.
**Scoring model** (for future implementation):
- Any of 1st/2nd/3rd picks landing in the actual top 3 → points
- 1st pick matching actual winner → bonus points
- Last pick matching actual last place → bonus points
## 3. Prediction UI — Tap-to-Assign
**Top section — 4 slot cards:**
- "1st Place", "2nd Place", "3rd Place", "Last Place"
- Empty slots show placeholder text
- Filled slots show the entry (flag + artist + song) with a tap-to-remove action
**Bottom section — scrollable entry list:**
- All entries from the lineup
- Already-assigned entries are dimmed/disabled
- Tapping an unassigned entry shows a small picker with only unfilled slots (1st/2nd/3rd/Last)
- After selecting a slot, the entry fills that slot and dims in the list
**Submit button:** Appears when all 4 slots are filled. After submission or when predictions are locked, the UI becomes read-only showing assigned entries in their slots.
**Locked state:** When advancing past Pre-Show, predictions lock. The form shows the player's submitted picks (or "Not submitted" if they missed the window).
## 4. Remove Dish of the Nation
Strip the entire Dish of the Nation feature:
**Server:**
- Remove dish WS message handlers from `handler.ts`
- Remove dish methods from `GameManager`
- Remove dish persistence from `GameService`
- Remove dish DB tables (`dishes`, `dish_guesses`) from schema
**Client:**
- Delete `dish-list.tsx`, `dish-host.tsx`, `dish-results.tsx`
- Remove dish state slices and actions from `room-store.ts`
- Remove dish WS message handlers from `use-websocket.ts`
- Remove dish UI from routes (`play`, `host`, `display`)
**Shared:**
- Remove dish schemas from `game-types.ts`
- Remove dish WS message types from `ws-messages.ts`
## 5. Player List — Prediction Checkmark
Add prediction submission status to the player state broadcast:
- Server: When building room state or game state, include `hasSubmittedPrediction: boolean` per player by checking if a prediction exists in the GameManager
- Client: Player list component renders a checkmark icon (✓) next to player names that have submitted predictions
- Visible on all views (play, host, display)
## 6. Acts Naming
Rename internal act identifiers and add display names:
```ts
const ACTS = ["lobby", "pre-show", "live-event", "scoring", "ended"] as const
```
| Internal ID | Display Name | Timing Intent |
|----------------|---------------|----------------------------------|
| `lobby` | Lobby | Waiting room, players join |
| `pre-show` | Pre-Show | Before broadcast, predictions |
| `live-event` | Live Event | During broadcast |
| `scoring` | Scoring | After results, leaderboard |
| `ended` | Ended | Party over |
Host control buttons: "Start Pre-Show", "Start Live Event", "Start Scoring", "End Party".
Predictions lock when advancing from Pre-Show to Live Event (previously act1 → act2).
## 7. Lobby Code — Copy to Clipboard
On the display view (and anywhere the room code is shown prominently):
- Wrap the room code in a tappable/clickable element
- On click: `navigator.clipboard.writeText(roomCode)`
- Show brief "Copied!" feedback (tooltip or temporary text swap)
- Style to indicate interactivity (cursor pointer, subtle hover state)
## Data Flow Changes
### Prediction Flow (updated)
1. Client taps entry → selects slot → slot fills in UI
2. Client fills all 4 slots → submits `submit_prediction` with `{ first, second, third, last }`
3. Server validates: all 4 distinct, all valid country codes
4. Server stores in GameManager, persists to DB
5. Server broadcasts updated game state (includes `hasSubmittedPrediction` per player)
6. All clients update player list checkmarks
### Act Progression (updated names)
```
lobby → pre-show → live-event → scoring → ended
```
Predictions lock on `pre-show → live-event` transition.
