 ## Correções pendentes

 | Problema | Causa provável | Correção |
 |---|---|---|
-| **Enviar som ao soundboard não funciona no app desktop** (funciona no navegador) | `SoundboardPopover` pede o nome do som com `window.prompt`, que o **Electron não implementa** — não abre nada e devolve vazio, então o fluxo aborta em silêncio, sem erro. `window.prompt` aparece em exatamente um lugar no projeto: esse. O resto do código já o evitava | Trocar por um campo de texto dentro do próprio popover (ou um modal reutilizável). Some o prompt e passa a funcionar igual nos dois. **Vale criar o modal de entrada genérico**, já que não existe nenhum e outras features vão precisar |
-| **Eco absurdo ao compartilhar tela com som** (app desktop) | O `loopback` do Electron captura a mistura de saída do sistema **inteiro**, que inclui o próprio Backspace tocando a voz dos outros. Essa voz volta para eles dentro da transmissão, com atraso. Não é eco acústico — é digital, então **fone não resolve**. As constraints do web (`restrictOwnAudio`) nunca chegam: o handler ignora o `_request` e monta o stream a partir do enum. É também por isso que `shareAudio` já vinha desligado por padrão no app | **Implementado (2026-09-01), não testado.** Trocado por `electron-native-screenshare`: captura com isolamento por processo — só a janela compartilhada (include) ou tudo menos este app (exclude). O PCM vai do processo principal ao renderer por IPC e vira faixa publicada no LiveKit. **Exige gerar instalador novo e reinstalar**, e só pode ser confirmado numa máquina Windows |
-| **Bloco do Spotify dessincronizado** (mostra a faixa errada por um tempo) | Soma de duas esperas: a consulta roda a cada **20s** (`useSpotifyActivity`) e o envio pelo WebSocket ainda passa por um **debounce de 5s** no `activityStore`. Na pior hipótese os outros veem a música anterior por ~25s | Consultar de novo perto do fim da faixa (a duração é conhecida) em vez de só por intervalo fixo, e encurtar o debounce para esta fonte |
-| **Bloco do Spotify some sozinho** | Três caminhos apagam a atividade inteira: faixa **pausada** (`is_playing: false` devolve `null`), o **vão entre faixas** (o Spotify responde `204`) e qualquer falha transitória. Some e volta = a piscada que você viu | Manter a última faixa conhecida por alguns segundos antes de apagar, e enviar um estado *pausado* explícito em vez de sumir com o bloco |
-| **Barra de progresso errada / andando pausada** | Duas causas independentes: (1) o progresso é derivado de carimbos calculados com o relógio do **servidor** e desenhado contra o relógio de **quem olha** — se os relógios divergem, a barra fica deslocada; (2) a barra continua avançando localmente depois que a pessoa pausa, até a próxima consulta | Enviar o horário do servidor junto no payload para o cliente corrigir a diferença, e congelar a barra quando o estado for pausado |
