# Round Type: LIVE_FINAL — Live Finals Documentation

## Overview

The **LIVE_FINAL** round type orchestrates the live ceremony where Jury 3 evaluates finalist presentations in real-time. This is Round 7 in the redesigned 8-step competition flow. It combines jury scoring, optional audience participation, deliberation periods, and live results display into a single managed event.

**Core capabilities:**
- Real-time stage manager controls (presentation cursor, timing, pause/resume)
- Jury voting with multiple modes (numeric, ranking, binary)
- Optional audience voting with weighted scores
- Per-category presentation windows (STARTUP window, then CONCEPT window)
- Deliberation period for jury discussion
- Live results display or ceremony reveal
- Anti-fraud measures for audience participation

**Round 7 position in the flow:**
```
Round 1: Application Window (INTAKE)
Round 2: AI Screening (FILTERING)
Round 3: Jury 1 - Semi-finalist Selection (EVALUATION)
Round 4: Semi-finalist Submission (SUBMISSION)
Round 5: Jury 2 - Finalist Selection (EVALUATION)
Round 6: Finalist Mentoring (MENTORING)
Round 7: Live Finals (LIVE_FINAL) ← THIS DOCUMENT
Round 8: Confirm Winners (CONFIRMATION)
```

## Stage Manager — Admin Controls

The **Stage Manager** is the admin control panel for orchestrating the live ceremony. It provides real-time control over presentation flow, voting windows, and emergency interventions.

### Ceremony State Machine

```
Ceremony State Flow:
NOT_STARTED → (start session) → IN_PROGRESS → (deliberation starts) → DELIBERATION → (voting ends) → COMPLETED

NOT_STARTED:
  - Session created but not started
  - Projects ordered (manual or automatic)
  - Jury and audience links generated
  - Stage manager can preview setup

IN_PROGRESS:
  - Presentations ongoing
  - Per-project state: WAITING → PRESENTING → Q_AND_A → VOTING → VOTED → SCORED
  - Admin can pause, skip, reorder on the fly

DELIBERATION:
  - Timer running for deliberation period
  - Jury can discuss (optional chat/discussion interface)
  - Votes may be revised (if deliberationAllowsVoteRevision=true)
  - Admin can extend deliberation time

COMPLETED:
  - All voting finished
  - Results calculated
  - Ceremony locked (or unlocked for result reveal)
```

### Per-Project State

Each project in the live finals progresses through these states:

```
WAITING       → Project queued, not yet presenting
PRESENTING    → Presentation in progress (timer: presentationDurationMinutes)
Q_AND_A       → Q&A session (timer: qaDurationMinutes)
VOTING        → Voting window open (jury + audience can vote)
VOTED         → Voting window closed, awaiting next action
SCORED        → Scores calculated, moving to next project
SKIPPED       → Admin skipped this project (emergency override)
```
