# Live Control Specification

## Source of Truth
Admin cursor state is the single source of truth for active project context during live stages.

## Core Controls

- start session
- next/previous
- jump to project
- reorder queue
- open/close cohort windows
- pause/resume session

## Runtime Requirements

1. cursor updates are versioned
2. race conditions return `CONFLICT` and require refresh/retry
3. real-time propagation to jury and audience clients
4. reconnect path converges to current cursor/window state

## Vote Acceptance Rules

- stage and cohort windows must be open
- dedupe key policy enforced (`session/cohort/project/voter/window`)
- closed windows reject submissions deterministically

## Event Contract

- `live.cursor.updated`
- `cohort.window.changed`
- `live.session.state.changed`
