+# Bluesky Integration Plan
+
+## Overview
+
+Bluesky uses o protocolo AT (ATProto) e não usa OAuth tradicional. A autenticação é feita com username/password que retorna JWT tokens.
+
+## Arquitetura
+
+### Autenticação
+- **Não usa OAuth** - usa login com identifier (handle/email) + password
+- Retorna `accessJwt` (curta duração) e `refreshJwt` (longa duração)
+- Suporta instâncias customizadas (não só bsky.social)
+
+### Endpoints Principais
+- `com.atproto.server.createSession` - Login
+- `com.atproto.server.refreshSession` - Refresh token
+- `com.atproto.repo.createRecord` - Criar post
+- `com.atproto.repo.uploadBlob` - Upload de mídia
+
+### Limitações
+- **Texto**: 300 caracteres
+- **Imagens**: Máximo 4, até 1MB cada
+- **Vídeo**: Máximo 1 (não pode misturar com múltiplas imagens)
+
+---
+
+## Implementação
+
+### 1. Dependências
+
+```bash
+composer require socialiteproviders/bluesky
+# OU usar HTTP client direto já que não é OAuth
+```
+
+Alternativa: Usar HTTP client direto (recomendado, como postiz faz).
+
+### 2. Arquivos a Criar/Modificar
+
+#### Novos Arquivos
+- `app/Http/Controllers/Auth/BlueskyController.php` - Controller de conexão
+- `app/Services/Social/BlueskyPublisher.php` - Serviço de publicação
+- `resources/js/components/posts/previews/BlueskyPreview.vue` - Preview component
+- `resources/js/pages/accounts/BlueskyConnect.vue` - Tela de conexão (custom, não OAuth popup)
+
+#### Arquivos a Modificar
+- `app/Enums/SocialAccount/Platform.php` - Adicionar Bluesky
+- `app/Enums/PostPlatform/ContentType.php` - Adicionar BlueskyPost
+- `app/Jobs/PublishToSocialPlatform.php` - Registrar BlueskyPublisher
+- `config/trypost.php` - Adicionar toggle de plataforma
+- `routes/web.php` - Adicionar rotas
+- `resources/js/components/posts/previews/PlatformPreview.vue` - Importar BlueskyPreview
+- `resources/js/components/posts/previews/index.ts` - Exportar BlueskyPreview
+- `resources/js/pages/posts/Edit.vue` - Adicionar logo/label
+

+
+### 3. Platform Enum
+
+```php
+case Bluesky = 'bluesky';
+
+public function label(): string
+{
+    return match ($this) {
+        // ...
+        self::Bluesky => 'Bluesky',
+    };
+}
+
+public function color(): string
+{
+    return match ($this) {
+        // ...
+        self::Bluesky => '#0085FF',
+    };
+}
+
+public function maxContentLength(): int
+{
+    return match ($this) {
+        // ...
+        self::Bluesky => 300,
+    };
+}
+
+public function maxImages(): int
+{
+    return match ($this) {
+        // ...
+        self::Bluesky => 4,
+    };
+}
+
+public function supportsTextOnly(): bool
+{
+    return match ($this) {
+        // ...
+        self::Bluesky => true,
+    };
+}
+```
+
+---
+
+### 4. ContentType Enum
+
+```php
+case BlueskyPost = 'bluesky_post';
+
+public static function defaultFor(Platform $platform): ?self
+{
+    return match ($platform) {
+        // ...
+        Platform::Bluesky => self::BlueskyPost,
+    };
+}
+```
+
+---
+
+### 5. BlueskyController (Conexão Custom)
+
+Como Bluesky não usa OAuth, precisamos de uma tela custom para inserir credenciais.

+
+### 9. BlueskyPreview.vue
+
+Similar ao ThreadsPreview, com layout simples de texto e imagens.
+
+---
+
+### 10. Assets
+
+- Adicionar `public/images/accounts/bluesky.png` (logo do Bluesky)
+
+---
+
+## Ordem de Implementação
+
+1. [ ] Adicionar Bluesky ao Platform enum
+2. [ ] Adicionar BlueskyPost ao ContentType enum
+3. [ ] Criar BlueskyController
+4. [ ] Adicionar rotas
+5. [ ] Criar BlueskyConnect.vue (frontend)
+6. [ ] Criar BlueskyPublisher service
+7. [ ] Registrar no PublishToSocialPlatform job
+8. [ ] Criar BlueskyPreview.vue
+9. [ ] Atualizar PlatformPreview.vue
+10. [ ] Atualizar Edit.vue (logo, label)
+11. [ ] Adicionar config em trypost.php
+12. [ ] Adicionar logo
+13. [ ] Testar conexão
+14. [ ] Testar publicação
+
+---
+
+## Considerações de Segurança
+
+- **App Password**: Recomendado usar App Password ao invés da senha principal
+- **Armazenamento**: Password é encriptado no campo `meta`
+- **Token Refresh**: JWT tokens expiram rápido, refresh automático implementado
+
+---
+
+## Diferenças do OAuth
+
+| Aspecto | OAuth (Pinterest, etc) | Bluesky |
+|---------|------------------------|---------|
+| Fluxo | Popup redirect | Formulário inline |
+| Tokens | Via OAuth provider | Via API direta |

+# Mastodon Integration Plan
+
+## Overview
+
+Mastodon é uma rede social federada que usa OAuth 2.0 para autenticação. Diferente de outras plataformas, cada usuário pode estar em uma instância (servidor) diferente, o que requer suporte a múltiplas instâncias.
+
+## Arquitetura
+
+### Autenticação
+- **Usa OAuth 2.0** - fluxo padrão de autorização
+- **Suporte a múltiplas instâncias** - não apenas mastodon.social
+- **App registration dinâmico** - para instâncias customizadas
+- **Scopes necessários**: `read:accounts`, `write:statuses`, `write:media`
+
+### Endpoints Principais
+- `POST /api/v1/apps` - Registrar aplicação (para instâncias customizadas)
+- `GET /oauth/authorize` - Autorização do usuário
+- `POST /oauth/token` - Obter access token
+- `GET /api/v1/accounts/verify_credentials` - Dados do usuário
+- `POST /api/v1/statuses` - Criar post (toot)
+- `POST /api/v1/media` - Upload de mídia
+
+### Limitações
+- **Texto**: 500 caracteres (padrão, pode variar por instância)
+- **Imagens**: Máximo 4 por post
+- **Vídeo**: Suportado
+- **Visibilidade**: public, unlisted, private, direct
+
+---
+
+## Implementação
+
+### 1. Arquivos a Criar/Modificar
+
+#### Novos Arquivos
+- `app/Http/Controllers/Auth/MastodonController.php` - Controller de conexão
+- `app/Services/Social/MastodonPublisher.php` - Serviço de publicação
+- `resources/js/components/posts/previews/MastodonPreview.vue` - Preview component
+- `resources/js/pages/accounts/MastodonConnect.vue` - Tela para inserir instância
+
+#### Arquivos a Modificar
+- `app/Enums/SocialAccount/Platform.php` - Adicionar Mastodon
+- `app/Enums/PostPlatform/ContentType.php` - Adicionar MastodonPost
+- `app/Jobs/PublishToSocialPlatform.php` - Registrar MastodonPublisher
+- `config/services.php` - Adicionar config Mastodon (para mastodon.social padrão)
+- `config/trypost.php` - Adicionar toggle de plataforma
+- `routes/web.php` - Adicionar rotas
+- `resources/js/components/posts/previews/PlatformPreview.vue` - Importar MastodonPreview
+- `resources/js/components/posts/previews/index.ts` - Exportar MastodonPreview
+- `resources/js/pages/posts/Edit.vue` - Adicionar logo/label

+### 2. Platform Enum
+
+```php
+case Mastodon = 'mastodon';
+
+public function label(): string
+{
+    return match ($this) {
+        // ...
+        self::Mastodon => 'Mastodon',
+    };
+}
+
+public function color(): string
+{
+    return match ($this) {
+        // ...
+        self::Mastodon => '#6364FF',
+    };
+}
+
+public function maxContentLength(): int
+{
+    return match ($this) {
+        // ...
+        self::Mastodon => 500,
+    };
+}
+
+public function maxImages(): int
+{
+    return match ($this) {
+        // ...
+        self::Mastodon => 4,
+    };
+}
+
+public function supportsTextOnly(): bool
+{
+    return match ($this) {
+        // ...
+        self::Mastodon => true,
+    };
+}
+```
+
+---
+
+### 3. ContentType Enum
+
+```php
+case MastodonPost = 'mastodon_post';
+
+public static function defaultFor(Platform $platform): ?self
+{
+    return match ($platform) {
+        // ...
+        Platform::Mastodon => self::MastodonPost,
+    };
+}
+```

+### 8. MastodonPreview.vue
+
+Similar ao ThreadsPreview, estilo de timeline com texto e mídia.
+
+---
+
+## Ordem de Implementação
+
+1. [ ] Adicionar Mastodon ao Platform enum
+2. [ ] Adicionar MastodonPost ao ContentType enum
+3. [ ] Criar MastodonController
+4. [ ] Adicionar rotas
+5. [ ] Criar MastodonConnect.vue (frontend)
+6. [ ] Criar MastodonPublisher service
+7. [ ] Registrar no PublishToSocialPlatform job
+8. [ ] Criar MastodonPreview.vue
+9. [ ] Atualizar PlatformPreview.vue
+10. [ ] Atualizar Edit.vue (logo, label)
+11. [ ] Adicionar config em trypost.php
+12. [ ] Testar conexão com mastodon.social
+13. [ ] Testar conexão com instância customizada
+14. [ ] Testar publicação

+
+## Diferenças do Bluesky
+
+| Aspecto | Bluesky | Mastodon |
+|---------|---------|----------|
+| Auth | Credentials (JWT) | OAuth 2.0 |
+| Instâncias | bsky.social (único) | Múltiplas (federado) |
+| App Registration | Não necessário | Dinâmico por instância |
+| Token Expiry | 2 horas (refresh) | Não expira |
+| Char Limit | 300 | 500 |
+| Callback | Não | Sim (OAuth) |
+
+---
+
+## Considerações
+
+### Multi-Instance
+- O usuário precisa informar sua instância antes de conectar
+- App é registrado dinamicamente em cada instância
+- client_id e client_secret são salvos no campo `meta` da conta
+
+### Tokens
+- Tokens Mastodon não expiram normalmente
+- Não precisa de refresh token logic
+- Se token inválido, usuário precisa reconectar
+
+---
