+# ROADMAP — Plano de qualidade "nota 10"
+
+Plano de implementação para elevar o Codout.Framework da avaliação atual
+(**6,5/10**, jun/2026) até **10/10**. As fases estão em ordem de execução
+recomendada: cada uma cria a base da seguinte. Os ganhos de nota são
+estimativas para acompanhamento, não ciência exata.
+
+## Princípios
+
+- **Não quebrar consumidores**: pacotes já publicados no NuGet.org seguem
+  SemVer. Mudança que altere API pública exige bump major e aviso no
+  CHANGELOG.
+- **Cada pacote anda no próprio ritmo**: bumps de versão apenas nos pacotes
+  efetivamente tocados (ver CLAUDE.md).
+- **CI primeiro**: nenhuma fase é considerada concluída sem o `dotnet.yml`
+  verde validando o resultado.
+
+---
+
+## Fase 1 — Quick wins de CI e higiene (esforço: pequeno · ganho: +0,25)
+
+Correções de baixo risco que destravam o resto.
+
+- [ ] `dotnet.yml`: atualizar `dotnet-version` de `9.0.x` para `10.0.x`
+      (o core targeta `net10.0` via `Directory.Build.props`).
+- [ ] Adicionar `Codout.Framework.Api.Dto` e `Softprime.Multitenancy` à
+      `Codout.Framework.sln` (estão no `release-packages.json` mas fora da
+      solution — hoje o CI de PR não os builda).
+- [ ] Remover `appveyor.yml` (referencia Visual Studio 2012; o pipeline real
+      é GitHub Actions).
+- [ ] Corrigir badge de build do README (aponta para `build.yml`/`dotnet.yml`
+      de forma inconsistente).
+
+**Critério de aceite**: `dotnet build` da solution verde no CI com SDK 10.
+
+## Fase 2 — Testes na solution (esforço: pequeno · ganho: +0,25)
+
+Hoje os 4 projetos de teste existem fora da solution; o `dotnet test
+Codout.Framework.sln` do `release.yml` roda zero testes.
+
+- [ ] Criar pasta `tests/` na raiz.
+- [ ] Migrar `NetCore/Codout.Framework.EF.Tests` para
+      `tests/Codout.Framework.EF.Tests` e atualizar `TEST_PROJECT` no
+      `core-release.yml` (linha 39).
+- [ ] Adicionar os projetos de teste ativos (EF.Tests e, se viável por
+      caminho, Mcp.Tests) à `Codout.Framework.sln`.
+- [ ] Remover do escopo os testes legados (`NetFull/*.Tests`,
+      `NetCore/Codout.Framework.NetCore.Tests`) — dependem de infraestrutura
+      externa (appsettings com conexões reais) e serão substituídos na Fase 4.
+
+**Critério de aceite**: `dotnet test Codout.Framework.sln` executa testes de
+verdade (> 0) no CI de PR e no gate do `release.yml`.
+
+## Fase 3 — Limpeza do legado (esforço: médio · ganho: +1,0)
+
+Remover ~2.000 linhas de código morto que distorcem a leitura do repo e
+impedem políticas globais de qualidade (Fase 5).
+
+- [ ] **Decisão prévia (usuário)**: deletar ou arquivar em branch
+      `archive/legacy` antes de remover. Recomendação: branch de arquivo +
+      remoção do master.
+- [ ] Remover `NetFull/` (EF6, .NET Framework — EOL).
+- [ ] Remover `NetCore/` (netcoreapp2.x — EOL; testes já migrados na Fase 2).
+- [ ] Remover `src/NetCore/` (Cosmos e DocumentDB em `netcoreapp2.0` com SDK
+      `Microsoft.Azure.DocumentDB.Core` descontinuado e anti-padrão
+      `AllAsync().Result` em `CosmosRepository.cs`). Se houver demanda real
+      por Cosmos, recriar do zero como `Codout.Framework.Cosmos` com SDK
+      `Microsoft.Azure.Cosmos` — fora do escopo deste plano.
+- [ ] Remover `Codout.Framework.DP` (quebrado: referencia
+      `Codout.Framework.DAL` inexistente; `IsPackable=false`).
+- [ ] Remover/renomear `Shared/Codout.Framework.Shared.Commom` (typo
+      "Commom") e avaliar se `Shared/` ainda tem consumidor.
+- [ ] Atualizar CLAUDE.md (seção "Pacotes excluídos do release automatizado")
+      e CHANGELOG (`### Repository`) refletindo as remoções.
+
+**Critério de aceite**: nenhum csproj com target EOL no repo; busca por
+"Commom" retorna vazio.
+
+## Fase 4 — Cobertura de testes (esforço: grande · ganho: +1,5)
+
+O maior gap: 19 de 23 pacotes publicáveis sem teste algum. Priorizar por
+risco × facilidade, em `tests/<Pacote>.Tests`:
+
+| Onda | Pacotes | Abordagem |
+|------|---------|-----------|
+| 1 | Data, Domain, Common, DynamicLinq, Security.* | Unit puro (sem I/O) — maior retorno imediato |
+| 2 | EF (ampliar), Mongo, NH | EF: SQLite in-memory; Mongo: Testcontainers ou EphemeralMongo; NH: SQLite |
+| 3 | Mailer, Mailer.Razor, Api.Client, Storage | Fakes/mocks (HttpMessageHandler fake, template rendering, contratos de abstração) |
+| 4 | Storage.Azure, Mailer.AWS, Mailer.SendGrid, Api, Application, Multitenancy | Azurite para Azure; demais via mocks dos SDKs |
+
+- [ ] Onda 1 concluída e no CI.
+- [ ] Onda 2 concluída (Testcontainers exige Docker no runner — `ubuntu-latest` já tem).
+- [ ] Onda 3 concluída.
+- [ ] Onda 4 concluída.
+- [ ] Coleta de cobertura com `coverlet.collector` + publicação de relatório
+      no CI (artifact ou Codecov + badge no README).
+- [ ] Meta de cobertura: ≥ 70 % nos pacotes core (Data/Domain/Common/EF),
+      ≥ 50 % nos demais.
+
+**Critério de aceite**: todo pacote publicável tem projeto de teste; metas de
+cobertura atingidas e visíveis no CI.
+
+## Fase 5 — Qualidade estática (esforço: médio · ganho: +0,75)
+
+Aplicar via `Directory.Build.props` (depois da Fase 3, para não gastar
+esforço em código morto):
+
+- [ ] `<Nullable>enable</Nullable>` global, corrigindo projetos em ondas
+      (13/37 já têm). Para projetos ainda não migrados, opt-out temporário
+      explícito no csproj com comentário `TODO`.
+- [ ] `<TreatWarningsAsErrors>true</TreatWarningsAsErrors>` +
+      `<EnableNETAnalyzers>true</EnableNETAnalyzers>` +
+      `<AnalysisLevel>latest-recommended</AnalysisLevel>`.
+- [ ] Expandir `.editorconfig` com convenções C# (indentação, naming,
+      `dotnet_diagnostic.*` para calibrar severidade dos analyzers).
+- [ ] Resolver os `[Obsolete]` pendentes em `Codout.Framework.Common`
+      (Crypto, NumericExtensions, WebPageFetcher): remover no próximo bump
+      major ou documentar substitutos.
+- [ ] Atualizar `System.ComponentModel.Annotations` 5.0.0 → versão atual (ou
+      remover a referência onde o shared framework já cobre).
+
+**Critério de aceite**: `dotnet build` sem warnings na solution inteira;
+nullable ativo em 100 % dos projetos publicáveis.
+
+## Fase 6 — Empacotamento profissional (esforço: médio · ganho: +0,75)
+
+Tudo no `Directory.Build.props`, exceto onde indicado:
+
+- [ ] SourceLink: `Microsoft.SourceLink.GitHub`, `PublishRepositoryUrl`,
+      `EmbedUntrackedSources`, `IncludeSymbols` + `SymbolPackageFormat=snupkg`.
+- [ ] `ContinuousIntegrationBuild=true` nos workflows de release (build
+      determinístico).
+- [ ] `PackageReadmeFile`: criar `README.md` curto por pacote (o que é,
+      instalação, exemplo mínimo) e empacotar — hoje 19/20 pacotes têm página
+      vazia no NuGet.org.
+- [ ] `Description` e `PackageTags` individualizados em cada csproj.
+- [ ] Publicar os snupkg no fluxo de release (NuGet.org aceita no mesmo
+      `dotnet nuget push`).
+- [ ] Republicar pacotes com bump **patch** (mudança só de empacotamento) —
+      confirmar com o usuário antes, pois publicar exige tag.
+
+**Critério de aceite**: página de cada pacote no NuGet.org com README, ícone
+e símbolos depuráveis (F12 no código do framework a partir de um consumidor).
+
+## Fase 7 — Documentação (esforço: médio · ganho: +0,5)
+
+- [ ] Reescrever a tabela de módulos do README: remover "Zenvia", "DAL",
+      "Kendo.DynamicLinq", "DP", "Shared"; incluir Security.*, Storage,
+      Storage.Azure, Application, Mcp, Image.Extensions.
+- [ ] Seção "Qual pacote eu instalo?" com cenários comuns (EF + API,
+      Mongo, multitenancy, mailer).
+- [ ] `GenerateDocumentationFile=true` global (via `Directory.Build.props`)
+      e completar XML docs nos tipos públicos de `Domain`, `Common`, `Data`
+      e `Api` — com `TreatWarningsAsErrors` da Fase 5, o CS1591 força a
+      conclusão (calibrar severidade se necessário).
+- [ ] Atualizar instruções de build/teste do README (caminhos reais da
+      pasta `tests/`).
+
+**Critério de aceite**: README sem referência a módulo inexistente; XML docs
+completos nos 4 pacotes core.
+
+## Fase 8 — Hardening de CI/CD (esforço: pequeno · ganho: +0,5)
+
+- [ ] Dependabot (`.github/dependabot.yml`) para NuGet + GitHub Actions,
+      agrupando updates minor/patch.
+- [ ] CodeQL (`github/codeql-action`) para análise de segurança em PR.
+- [ ] Gate de cobertura no `dotnet.yml` (falhar se cair abaixo da meta).
+- [ ] Branch protection em `master`: exigir CI verde + 1 review (config no
+      GitHub, não no repo).
+- [ ] Concurrency/cancel-in-progress nos workflows de PR para economizar
+      runner.
+
+**Critério de aceite**: PRs só mergeiam com CI + CodeQL verdes; dependências
+atualizadas automaticamente via PRs do Dependabot.
+
+---
+
+## Resumo de progressão
+
+| Fase | Tema | Esforço | Nota acumulada (alvo) |
+|------|------|---------|----------------------|
+| — | Estado atual | — | 6,5 |
+| 1 | Quick wins CI | P | 6,75 |
+| 2 | Testes na solution | P | 7,0 |
+| 3 | Limpeza do legado | M | 8,0 |
+| 4 | Cobertura de testes | G | 9,5 *(maior fase — pode rodar em paralelo às 5–8)* |
+| 5 | Qualidade estática | M | +0,75 dentro do teto |
+| 6 | Empacotamento | M | +0,75 dentro do teto |
+| 7 | Documentação | M | +0,5 dentro do teto |
+| 8 | Hardening CI/CD | P | **10,0** |
+
+## Pontos de decisão (perguntar ao usuário antes de executar)
+
+1. **Fase 3**: deletar legado direto ou arquivar em branch `archive/legacy`
+   primeiro? (Recomendação: arquivar e deletar.)
+2. **Fase 4, onda 2**: Testcontainers (fiel, requer Docker) vs. bibliotecas
+   in-memory (mais rápido, menos fiel) para Mongo.
+3. **Fase 6**: republicar todos os pacotes com bump patch após SourceLink/
+   README, ou deixar para o próximo release natural de cada pacote?
+4. **Fase 5**: `[Obsolete]` de `Common` — remover em bump major agora ou
+   manter até 7.0?

Remove ~2k linhas de código morto: targets EOL (netcoreapp2.0, EF6),
typo 'Commom', Codout.Framework.DP quebrado e appveyor remanescentes.
Nenhum desses projetos era publicado no NuGet; histórico preservado
no git. Atualiza CLAUDE.md e CHANGELOG.

+- Removidas as árvores legadas `NetFull/`, `NetCore/`, `src/NetCore/` (Cosmos/DocumentDB em `netcoreapp2.0`, EOL), `Codout.Framework.DP` (quebrado, referenciava `Codout.Framework.DAL` inexistente), `Shared/Codout.Framework.Shared.Commom` e `Shared.msbuild`. Nenhum desses projetos era publicado no NuGet (`IsPackable=false` ou fora de `.github/release-packages.json`); o histórico permanece no git. O typo "Commom" deixa de existir no repositório.
+- Removido `appveyor.yml` (referenciava Visual Studio 2012; o pipeline real é GitHub Actions).
+- `Codout.Framework.Api.Dto` e `Softprime.Multitenancy` adicionados à `Codout.Framework.sln`; `Softprime.Multitenancy` passou a usar `obj`/`bin` isolados para coexistir com `Codout.Multitenancy` na mesma pasta sem corromper o restore.
+- Testes movidos para a pasta `tests/` na raiz e incluídos na solution — `dotnet test Codout.Framework.sln` (CI de PR e gate do `release.yml`) agora executa os testes de verdade. `core-release.yml` atualizado para o novo caminho.
+
+### Build
+
+- `dotnet.yml`: SDK do CI atualizado de 9.0.x para 10.0.x, alinhado ao `TargetFramework` `net10.0` do `Directory.Build.props`.

+Em 2026-06-12 as árvores legadas foram **removidas do repositório** (histórico preservado no git): `NetFull/`, `NetCore/`, `src/NetCore/` (Cosmos/DocumentDB), `Codout.Framework.DP`, `Shared/` e `Shared.msbuild`. Nenhum deles era publicado no NuGet. Se o usuário pedir por um deles (ex.: suporte a Cosmos), a recomendação é recriar do zero como pacote moderno (ex.: `Codout.Framework.Cosmos` com SDK `Microsoft.Azure.Cosmos`) — não recuperar o código antigo do histórico sem modernizá-lo.
 
-- `Codout.Framework.DP` — implementa um `IRepository<T>` antigo (sem `Where`, `AllReadOnly`, `WherePaged`, `Refresh`, overloads de `CancellationToken`, etc.) e referencia a pasta legada `Codout.Framework.DAL` que não existe mais.
-- `src/NetCore/Codout.Framework.NetCore.Repository.Cosmos` — `netcoreapp2.0` (fora de suporte), SDK legado `Microsoft.Azure.DocumentDB.Core`, refs pra projetos `NetStandard.*` que sumiram do repo.
-- `src/NetCore/Codout.Framework.NetCore.Repository.DocumentDB` — idem.

-Se o usuário pedir pra publicar um deles, **avise que está deprecated** e pergunte se quer fazer o port completo antes (não tente packar como está — vai falhar).
+Os shared projects ativos na raiz (`Codout.Framework.Api.Shared`, `Codout.Framework.Dto.Shared`) **não** são legados — são `.shproj` importados por Api, Api.Client, Api.Dto e Application.

561 testes (10 projetos em tests/) cobrindo: extensões e helpers do
Common, hash+verify dos 3 providers de Security, contratos de Data,
identidade/igualdade de Domain, EFRepository+UnitOfWork contra SQLite
in-memory (incl. SaveOrUpdate 6.3.0), Mailer com mocks e renderização
Razor real, Storage e Storage.Azure offline.

Bugs pré-existentes encontrados estão documentados como
characterization tests e em tests/FINDINGS-{A,B,C}.md — nenhuma
mudança de comportamento em código de produção.

+# FINDINGS — Suítes de teste (Common, Security, Image.Extensions)
+
+Achados registrados durante a criação das suítes de teste. Nenhum código de
+produção foi alterado; os comportamentos abaixo estão documentados nos testes
+como *characterization tests* marcados com `// BUG?:`.
+
+## Codout.Framework.Common
+
+### 1. `StringExtensions.RemoveAccents` lança exceção em .NET moderno (e usa codepage errado)
+- Arquivo: `Codout.Framework.Common/Extensions/StringExtensions.cs`
+- O método usa `Encoding.GetEncoding("iso-8859-8")` (hebraico) para "remover
+  acentos". Em .NET (Core/5+) esse encoding não está registrado por padrão
+  (exigiria `CodePagesEncodingProvider`), então a chamada lança
+  `ArgumentException` em runtime. Mesmo se o encoding estivesse disponível, o
+  codepage correto para transliterar latinos seria outro (ex.: normalização
+  Unicode FormD, como o `SlugHelper` já faz).
+- Efeito colateral: `RemoveCharactersSpecial(..., replaceAccents: true)`
+  (caminho padrão) também lança a mesma exceção.
+- Teste: `StringExtensionsTests.RemoveAccents_ComportamentoAtual`.
+
+### 2. `StringExtensions.Chop(string backDownTo)` lança exceção quando o padrão não existe
+- Arquivo: `Codout.Framework.Common/Extensions/StringExtensions.cs`
+- Quando `LastIndexOf` retorna `-1`, o código chama `Remove(-1, 0)`, que lança
+  `ArgumentOutOfRangeException` em vez de retornar a string original.
+- Teste: `StringExtensionsTests.Chop_ComStringAlvoInexistente_LancaExcecao`.
+
+### 3. `StringExtensions.HtmlEncode` faz duplo escape do `&` das entidades
+- Arquivo: `Codout.Framework.Common/Extensions/StringExtensions.cs`
+- A substituição de `&` por `&amp;` acontece **depois** da geração das
+  entidades, então `é` vira `&amp;eacute;` em vez de `&eacute;`. O roundtrip
+  com `HtmlDecode` ainda funciona porque o decode desfaz na ordem inversa, mas
+  a saída não é HTML-encoding válido para consumo externo.
+- Teste: `StringExtensionsTests.HtmlEncode_HtmlDecode_SaoInversos`.
+
+### 4. `DateTimeExtensions.GetAge` erra a idade no dia do aniversário
+- Arquivo: `Codout.Framework.Common/Extensions/DateTimeExtensions.cs`
+- A comparação `dateOfBirth.DayOfYear < dateAsAt.DayOfYear` é estrita: no
+  próprio dia do aniversário a idade é subtraída em 1 (nascido em 15/06/2000,
+  em 15/06/2020 o método retorna 19 em vez de 20). A comparação por `DayOfYear`
+  também sofre desvio de 1 dia em anos bissextos.
+- Teste: `DateTimeExtensionsTests.GetAge_NoDiaDoAniversario_ComportamentoAtual`.
+
+### 5. `ValidationExtensions.IsEmail` considera string vazia/whitespace válida
+- Arquivo: `Codout.Framework.Common/Extensions/ValidationExtensions.cs`
+- `string.IsNullOrWhiteSpace(email) || Regex.IsMatch(...)` faz com que `""` e
+  `"   "` retornem `true`. Pode ser intencional (campo opcional), mas é
+  surpreendente para um validador chamado `IsEmail`.
+- Teste: `ValidationExtensionsTests.IsEmail_StringVazia_RetornaTrue`.
+
+### 6. `EnumHelper.GetLocalizedName` lê `Description` em vez de `Name` do `DisplayAttribute` (observação)
+- Arquivo: `Codout.Framework.Common/Helpers/EnumHelper.cs`
+- O método chama `DisplayAttribute.GetDescription()`; se o atributo for usado
+  como `[Display(Name = "...")]` (uso mais comum), o retorno é `null`. Os
+  testes usam `[Display(Description = "...")]` para refletir o comportamento
+  atual.
+- Teste: `EnumHelperTests.GetLocalizedName_ComDisplayAttribute_RetornaNome`.
+
+## Codout.Security (src/Security)
+
+### 7. `ArgonPasswordHash.NeedsRehash` usa tabela de parâmetros que não corresponde ao Sodium.Core
+- Arquivo: `src/Security/Codout.Security.Argon2/ArgonPasswordHash.cs`
+- `GetExpectedParameters()` assume as constantes do libsodium para argon2id
+  (`Interactive: t=2, m=65536 KiB; Moderate: t=3, m=262144 KiB`), mas o
+  Sodium.Core 1.4 gera hashes com outras constantes (verificado empiricamente):
+  - `Interactive`: `m=32768, t=4`
+  - `Moderate`: `m=131072, t=6`
+- Como o `m` armazenado é sempre menor que o esperado, **todo** hash gerado via
+  `Strength` (Interactive/Moderate) retorna `SuccessRehashNeeded` ao ser
+  verificado pelo mesmo hasher — nunca `Success` — induzindo rehash perpétuo a
+  cada login. Com `Argon2Options.OpsLimit`/`MemLimit` explícitos o roundtrip
+  funciona corretamente (`Success`).
+- Testes:
+  - `Argon2Tests.VerifyHashedPassword_SenhaCorreta_ComStrength_ComportamentoAtual`
+    (characterization do bug)
+  - `Argon2Tests.VerifyHashedPassword_SenhaCorreta_ComLimitesCustomizados_RetornaSuccess`
+    (caminho que funciona)
+- Obs.: o equivalente em Scrypt (`ScryptPasswordHash.NeedsRehash`) está correto
+  — o roundtrip com `Strength.Interactive` retorna `Success`
+  (`ScryptTests.VerifyHashedPassword_SenhaCorreta_RetornaSuccess`).
+
+## Codout.Image.Extensions
+
+Nenhum bug encontrado nas APIs testadas (`Extract`, `DrawRectangles`,
+`DrawPoints`, `DrawRectanglesAndPoints`). Os métodos de `GeometryExtensions`
+são `internal` e não foram testados para não alterar o código de produção
+(faltaria `InternalsVisibleTo`).

+# FINDINGS-B — Achados durante a escrita das suítes de teste
+
+Achados registrados durante a criação/ampliação das suítes de
+`Codout.Framework.Data.Tests`, `Codout.Framework.Domain.Tests` e
+`Codout.Framework.EF.Tests`. Nenhum código de produção foi alterado; cada item
+abaixo tem um characterization test marcado com `// BUG?:` documentando o
+comportamento ATUAL.
+
+## 1. `IAuditable` duplicada — o `AuditableInterceptor` ignora a abstração pública
+
+- **Caminho:** `Codout.Framework.EF/Interceptors/AuditableInterceptor.cs` (duplicata) e
+  `Codout.Framework.Data/Auditing/IAuditable.cs` (abstração pública).
+- **Descrição:** existem duas interfaces `IAuditable` com a mesma forma:
+  `Codout.Framework.Data.Auditing.IAuditable` e
+  `Codout.Framework.EF.Interceptors.IAuditable` (declarada no fim de
+  `AuditableInterceptor.cs`). Embora o arquivo do interceptor importe
+  `Codout.Framework.Data.Auditing`, a resolução de nomes do C# prioriza o tipo do
+  namespace corrente — o check `e.Entity is IAuditable` usa a duplicata LOCAL.
+  Resultado: entidades que implementam somente a abstração pública
+  `Data.Auditing.IAuditable` são **silenciosamente ignoradas** pela auditoria
+  automática (CreatedAt/CreatedBy/UpdatedAt/UpdatedBy nunca são preenchidos).
+  O mesmo arquivo também duplica `ICurrentUserProvider`
+  (vs. `Codout.Framework.Data/Auditing/ICurrentUserProvider.cs`), de modo que o
+  ctor do interceptor exige a duplicata local, não a abstração do pacote Data.
+- **Teste:** `tests/Codout.Framework.EF.Tests/InterceptorTests.cs` →
+  `Entity_implementing_only_the_Data_Auditing_IAuditable_is_not_audited`.
+- **Sugestão (não aplicada):** remover as interfaces duplicadas de
+  `AuditableInterceptor.cs` e usar as de `Codout.Framework.Data.Auditing`
+  (mudança potencialmente breaking para quem referencia os tipos do namespace
+  `Codout.Framework.EF.Interceptors` — avaliar bump minor/major).
+
+## 2. `EFRepository.RefreshAsync(entity, cancellationToken)` é síncrono e ignora o token
+
+- **Caminho:** `Codout.Framework.EF/EFRepository.cs`.
+- **Descrição:** o overload `RefreshAsync(T entity, CancellationToken cancellationToken)`
+  faz `Task.FromResult(Refresh(entity))`, ou seja, executa `Reload()` SÍNCRONO na
+  thread chamadora e ignora completamente o `CancellationToken` — mesmo um token
+  já cancelado não interrompe a operação. Inconsistente com o overload sem token,
+  que usa `ReloadAsync()`, e com o resto da superfície async (fix análogo já foi
+  feito no `SaveOrUpdateAsync` na 6.3.0).
+- **Teste:** `tests/Codout.Framework.EF.Tests/EFRepositoryAsyncTests.cs` →
+  `RefreshAsync_with_token_currently_ignores_cancellation`.
+- **Sugestão (não aplicada):** `await Context.Entry(entity).ReloadAsync(cancellationToken)`.
+
+## 3. Assimetria `Commit()` × `CommitAsync()` sem transação ativa
+
+- **Caminho:** `Codout.Framework.EF/EFUnitOfWork.cs`.
+- **Descrição:** `Commit()` sem transação ativa faz apenas `SaveChanges()`
+  (auto-commit do EF Core), mas `CommitAsync()` na mesma situação lança
+  `InvalidOperationException("Nenhuma transação ativa para commit...")`.
+  Código que funciona na via síncrona quebra ao migrar para a assíncrona.
+- **Teste:** `tests/Codout.Framework.EF.Tests/EFUnitOfWorkTests.cs` →
+  `CommitAsync_without_transaction_throws_unlike_sync_Commit`.
+- **Sugestão (não aplicada):** alinhar os dois contratos (provavelmente fazer o
+  `CommitAsync` aceitar auto-commit via `SaveChangesAsync`).
+
+## Observações menores (sem teste dedicado)
+
+- `EFUnitOfWork.Commit(IsolationLevel)` ignora o parâmetro `isolationLevel`
+  (há comentário no código explicando que o isolation level pertence ao
+  `BeginTransaction`); a existência do overload no contrato `IUnitOfWork` induz
+  o consumidor a achar que tem efeito.
+- Há também duas `ISoftDeletable` no ecossistema:
+  `Codout.Framework.Data.Auditing.ISoftDeletable` (IsDeleted/DeletedAt/DeletedBy,
+  usada pelo `SoftDeleteInterceptor`) e
+  `Codout.Framework.Domain.Interfaces.ISoftDeletable` (apenas `DeletedAt`).
+  Entidades que implementem só a versão do Domain não recebem soft delete
+  automático — mesmo padrão de armadilha do achado nº 1.

+# FINDINGS — suítes de teste Mailer / Storage (sessão C)
+
+Achados registrados durante a criação das suítes `Codout.Mailer.Tests`,
+`Codout.Mailer.Razor.Tests`, `Codout.Framework.Storage.Tests` e
+`Codout.Framework.Storage.Azure.Tests`. Nenhum código de produção foi alterado;
+os comportamentos abaixo estão cobertos por testes de caracterização
+(marcados com `// BUG?:` quando aplicável).
+
+## Codout.Mailer
+
+- **`Codout.Mailer/Services/MailerHealthCheck.cs`**
+  - A classe está no **namespace global** (o arquivo não declara `namespace`),
+    embora esteja na pasta `Services`.
+  - O campo `_dispatcher` é declarado mas **nunca atribuído nem usado** (não há
+    construtor) — o health check não verifica conectividade nenhuma e sempre
+    retorna `Healthy` (o próprio código tem o comentário "Implementar verificação
+    de conectividade"). Gera warning CS0169 no build.
+  - Coberto em `ConfigureServicesTests.MailerHealthCheck_DeveRetornarHealthy`.
+
+- **`Codout.Mailer/Services/MailerServiceBase.cs`**
+  - `model.To.Address` é acessado no log **antes** do bloco `try`; um model sem
+    destinatário derruba o chamador com `NullReferenceException` em vez de
+    retornar `MailerResponse { Sent = false }` como as demais falhas.
+  - Caracterizado em `MailerServiceBaseTests.Send_ComModelSemDestinatario_LancaNullReference`.
+
+- **`Codout.Mailer/Helpers/HtmlUtilities.cs`**
+  - `Cut(text, length)` com `length < 4` lança `ArgumentOutOfRangeException`
+    (slice `text[..(length - 4)]` com índice negativo).
+  - `CountWords` usa `Split(' ', '\n')` sem `RemoveEmptyEntries`: espaços
+    consecutivos inflam a contagem (`"uma  duas"` → 3).
+  - Caracterizados em `HtmlUtilitiesTests`.
+
+- **`Codout.Mailer/Helpers/Extensions.cs`**
+  - `ReadFully` força `stream.Position = 0`, exigindo stream *seekable*; streams
+    de rede/pipe lançam `NotSupportedException`.
+  - Caracterizado em `ExtensionsTests.ReadFully_ComStreamNaoSeekable_LancaNotSupportedException`.
+
+- **`Codout.Mailer/Models/MailerResponse.cs`**
+  - `ErrorMessages` não é inicializada (fica `null` em respostas de sucesso);
+    consumidores precisam checar `null` antes de iterar.
+
+## Codout.Mailer.AWS
+
+- **`Codout.Mailer.AWS/AWSDispatcher.cs`**
+  - O `AmazonSimpleEmailServiceV2Client` é **instanciado dentro de `Send`**
+    (não injetável). Não é possível testar a montagem da mensagem MIME nem o
+    tratamento da resposta do SES com fakes/handlers — só com chamada de rede
+    real, o que é proibido nos testes. A suíte cobre apenas as validações de
+    configuração (executadas antes de qualquer I/O) e o registro de DI.
+  - **Inconsistência**: a validação de settings (`AccessKey`/`RegionEndpoint`/
+    `SecretKey`) **lança `InvalidOperationException`**, enquanto qualquer outra
+    falha é convertida em `MailerResponse { Sent = false }` pelo `catch`.
+  - **Observação**: no caminho de sucesso, o `MessageId` retornado pelo SES é
+    colocado em `ErrorMessages` (semanticamente errado, é o campo de erros).
+  - Sugestão (não aplicada): receber `IAmazonSimpleEmailServiceV2` via construtor
+    para permitir fakes.
+
+## Codout.Mailer.SendGrid
+
+- **`Codout.Mailer.SendGrid/SendGridDispatcher.cs`**
+  - O `SendGridClient` é **instanciado dentro de `Send`** (não injetável). O SDK
+    tem construtor `SendGridClient(HttpClient, ...)` que permitiria interceptar
+    com `HttpMessageHandler` fake, mas o dispatcher não o expõe — montagem do
+    `SendGridMessage` e tratamento de resposta não são testáveis sem rede.
+  - `SendGridSettings.StandBox` (provável typo de **Sandbox**) **não é usado**
+    em lugar nenhum.
+  - Não há validação da `ApiKey` (nem na construção nem antes do envio).
+  - `Sent` só é `true` para `202 Accepted` (200 OK resultaria `false`) — correto
+    para a API v3 do SendGrid, registrado como observação.
+
+## Codout.Mailer.Razor
+
+- A renderização Razor real (compilação em runtime + template embarcado) **foi
+  possível** sem host ASP.NET Core completo: bastou `IWebHostEnvironment` fake,
+  `DiagnosticListener("Microsoft.AspNetCore")` e `PreserveCompilationContext`
+  habilitado no csproj de teste. Coberta em `RazorRenderingIntegrationTests`.
+- `RazorMailerOptions.Validate()` é `internal`, então a validação só é testável
+  através de `AddMailerRazor` (coberto em `ConfigureServicesTests`).
+- `RazorMailerOptions.EnableCache` **não é usado** em lugar nenhum (nem no
+  engine nem no `AddMailerRazor`).
+
+## Codout.Framework.Storage
+
+- O pacote define `FileSystemStorageOptions` e `AwsStorageOptions`, mas **não
+  existe implementação `IStorage` de file system nem de AWS S3** no repositório
+  (somente a do Azure). A suíte cobre exceções, options, models e valida o
+  contrato `IStorage` com um fake em memória
+  (`InMemoryStorageContractTests`).
+
+## Codout.Framework.Storage.Azure
+
+- **`Codout.Framework.Storage.Azure/AzureStorage.cs`**
+  - `GetBlobUri` com CDN habilitado **não faz URL-encoding do `fileName`**
+    (interpolação direta), enquanto o endpoint de blob (SDK) escapa caracteres
+    especiais — o mesmo blob gera URIs divergentes (ex.: espaço vs `%20`).
+    Caracterizado em `AzureStorageBlobUriTests.GetBlobUri_ComCdn_NaoEscapaNomeDoArquivo`.
+  - Connection string sintaticamente inválida não falha na construção (client é
+    `Lazy`); o erro só aparece no primeiro uso e **escapa como `FormatException`
+    do SDK** em vez de `StorageException` da abstração. Caracterizado em
+    `AzureStorageConstructionTests`.
+  - Operações que dependem de requisição real (Exists/Download/List/SAS/Upload
+    efetivo etc.) **não são testáveis offline**: o `BlobServiceClient` é criado
+    internamente a partir da connection string, sem ponto de injeção para um
+    client fake e sem Azurite no ambiente. A suíte cobre construção, validação
+    de argumentos (que ocorre antes de qualquer I/O), montagem de URIs
+    (local, sem rede) e o registro de DI.
+- **`Extensions/ServiceCollectionExtensions.cs`**
+  - `AddAzureStorage(options)` cria a instância de `AzureStorage` **eagerly no
+    momento do registro** (`AddSingleton` com instância), então options
+    inválidas falham no `AddAzureStorage`, não no primeiro resolve.
+    Caracterizado em `ServiceCollectionExtensionsTests`.
+
+## Observação de build (não é bug de produto)
+
+- `Directory.Build.props` liga `GeneratePackageOnBuild` globalmente; compilar os
+  projetos de teste dispara o pack dos projetos referenciados (e, fora da
+  solution, `$(SolutionDir)Packages` resolve para `<projeto>/Packages/`). Os
+  csproj de teste desligam isso para si mesmos; para não gerar `.nupkg` ao rodar
+  as suítes, use `dotnet test ... -p:GeneratePackageOnBuild=false`.

+# Contribuindo com o Codout.Framework
+
+Obrigado pelo interesse em contribuir! Este guia resume o essencial.
+
+## Antes de começar
+
+- Procure uma [issue existente](https://github.com/Codout/Codout.Framework/issues)
+  ou abra uma nova descrevendo o problema/proposta antes de PRs grandes.
+- O repositório usa UTF-8 (sem BOM), LF e newline final — já configurado em
+  `.editorconfig`.
+
+## Fluxo
+
+1. Faça um fork e crie uma branch: `git checkout -b feature/minha-mudanca`
+2. Implemente a mudança **com testes** (os projetos de teste ficam em `tests/`)
+3. Garanta build e testes verdes:
+   ```bash
+   dotnet build Codout.Framework.sln
+   dotnet test Codout.Framework.sln
+   ```
+4. Abra um Pull Request descrevendo motivação e impacto
+
+## Commits
+
+Seguimos [Conventional Commits](https://www.conventionalcommits.org/pt-br/):
+`fix:`, `feat:`, `chore:`, `docs:`, `ci:`, `refactor:`, `test:` — com escopo
+opcional pelo nome curto do pacote (ex.: `fix(ef): ...`). Mensagens em modo
+imperativo, primeira linha com até 72 caracteres.
+
+## Versionamento e releases
+
+- Cada pacote tem `<Version>` no próprio `.csproj` e segue
+  [SemVer](https://semver.org) — não versione pacotes que sua mudança não toca.
+- O CHANGELOG.md é por pacote, sob a data da mudança.
+- Releases são disparados por tag (`<short-name>-v<X.Y.Z>`) e publicados no
+  NuGet.org via GitHub Actions. O mapeamento de nomes curtos está em
+  `.github/release-packages.json`. Criação de tags é responsabilidade dos
+  mantenedores.
+
+## Compatibilidade
+
+- Mudanças que quebram API pública exigem bump **major** e destaque no
+  CHANGELOG.
+- Não remova membros `[Obsolete]` fora de um major.

+# Codout.DynamicLinq
+
+Wrapper para datasource de lista paginada: aplica paginação, ordenação, filtragem, agrupamento e agregações sobre qualquer `IQueryable<T>` usando Dynamic LINQ, retornando um resultado pronto para grids (ex.: Kendo UI DataSource).
+
+## Instalação
+
+```bash
+dotnet add package Codout.DynamicLinq
+```
+
+## Uso
+
+O ponto de entrada é o método de extensão `ToDataSourceResult` (classe `QueryableExtensions`), que recebe um `DataSourceRequest` (com `Take`, `Skip`, `Sort`, `Filter`, `Group` e `Aggregate`) e devolve um `DataSourceResult` com `Data`, `Total`, `Groups`, `Aggregates` e `Errors`:
+
+```csharp
+using Codout.DynamicLinq;
+
+[HttpPost]
+public DataSourceResult GetPedidos([FromBody] DataSourceRequest request)
+{
+    IQueryable<Pedido> query = _db.Pedidos.AsQueryable();
+    return query.ToDataSourceResult(request);
+}
+```
+
+Também é possível chamar o overload completo manualmente, informando `take`, `skip`, ordenação (`Sort`), filtro (`Filter`), agregações (`Aggregator`) e agrupamentos (`Group`):
+
+```csharp
+using Codout.DynamicLinq;
+
+var result = _db.Pedidos.AsQueryable().ToDataSourceResult(
+    take: 10,
+    skip: 0,
+    sort: new[] { new Sort { Field = "Data", Dir = "desc" } },
+    filter: new Filter
+    {
+        Logic = "and",
+        Filters = new[]
+        {
+            new Filter { Field = "Cliente", Operator = "contains", Value = "Maria" }
+        }
+    },
+    aggregates: Array.Empty<Aggregator>(),
+    group: Array.Empty<Group>());
+
+var pagina = result.Data;   // página atual
+var total = result.Total;   // total de registros (antes da paginação)
+```
+
+Observação: forneça coleções vazias (e não `null`) em `Sort`, `Group` e `Aggregate` quando não utilizá-los. Filtros sobre campos `DateTime` e `decimal` recebem conversão automática de tipo, e o operador `eq` em datas sem hora é expandido para o intervalo do dia.

+Cliente HTTP genérico e tipado para consumir as Web APIs CRUD construídas com Codout.Framework.Api, incluindo tratamento de erros padronizado.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Framework.Api.Client
+```
+
+## Uso
+
+`RestApiClient<T, TId>` implementa `IRestApi<TDto, TId>` (`GetAsync`, `PostAsync`, `PutAsync`, `DeleteAsync`, `GetAllAsync`) sobre um `HttpClient` configurado pela classe base `ApiClientBase`:
+
+```csharp
+using Codout.DynamicLinq;
+using Codout.Framework.Api.Client;
+
+public class ClienteDto : EntityDtoBase<Guid>
+{
+    public string Nome { get; set; }
+}
+
+var api = new RestApiClient<ClienteDto, Guid>("api/clientes", "https://api.exemplo.com/");
+// Ou, com autenticação via header "ApiKey":
+// var api = new RestApiClient<ClienteDto, Guid>("api/clientes", "https://api.exemplo.com/", apiKey);
+
+var criado = await api.PostAsync(new ClienteDto { Nome = "Maria" });
+var cliente = await api.GetAsync(criado.Id);
+
+DataSourceResult pagina = await api.GetAllAsync(new DataSourceRequest { Take = 20, Skip = 0 });
+await api.DeleteAsync(criado.Id);
+```
+
+Falhas HTTP são convertidas em `ApiClientException`, que carrega o `ApiException` retornado pelo servidor:
+
+```csharp
+try
+{
+    await api.GetAsync(id);
+}
+catch (ApiClientException ex)
+{
+    Console.WriteLine($"{ex.ApiException.StatusCode}: {ex.ApiException.Message}");

+Tipos base para classes DTO (Data Transfer Objects) trafegadas entre as APIs do Codout.Framework e seus clientes.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Framework.Api.Dto
+```
+
+## Uso
+
+O pacote fornece os contratos `IDto` e `IEntityDto<TId>` e as implementações base `Dto` e `EntityDto<TId>` (esta última expõe a propriedade `Id`). Observação: por razões históricas, os tipos residem no namespace `Codout.Framework.Api.Client`.
+
+```csharp
+using Codout.Framework.Api.Client;
+
+public class ClienteDto : EntityDto<Guid>
+{
+    public string Nome { get; set; }
+    public string Email { get; set; }
+}
+```
+
+DTOs sem identidade podem derivar de `Dto` ou implementar `IDto` diretamente:
+
+```csharp
+using Codout.Framework.Api.Client;
+
+public class ResumoVendasDto : Dto
+{
+    public decimal Total { get; set; }
+    public int Quantidade { get; set; }
+}
+```
+
+Esses mesmos tipos são usados como restrição genérica em `RestApiEntityBase<TEntity, TDto, TId>` (servidor), `RestApiClient<T, TId>` (cliente) e `CrudAppServiceBase<TEntity, TDto, TId>` (application service), garantindo um contrato único de transporte. O pacote tem target `netstandard2.1` e não possui dependências externas.

+# Codout.Framework.Domain
+
+Camada de domínio do Codout.Framework: classes base para entidades, value objects e contratos de auditoria/soft delete, com `Equals`/`GetHashCode` baseados em identidade ou em assinatura de domínio.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Framework.Domain
+```
+
+## Uso
+
+Declare uma entidade herdando de `Entity<TId>` (o `Id` é `virtual` e o setter é `protected`; use `SetId` quando precisar atribuir manualmente). Para o caso comum de PK `Guid?`, herde de `EntityBase`; para Guid gerado pela aplicação no construtor, use `ClientGeneratedEntity`; para campos de auditoria (`CreatedAt`, `UpdatedAt`, `CreatedBy`, `UpdatedBy`), use `AuditEntityBase` ou `AuditEntity<TId>`:
+
+```csharp
+using Codout.Framework.Domain.Base;
+using Codout.Framework.Domain.Entities;
+
+public class Cliente : EntityBase // Entity<Guid?>
+{
+    [DomainSignature] // participa do Equals/GetHashCode enquanto a entidade é transient
+    public virtual string Documento { get; set; }
+
+    public virtual string Nome { get; set; }
+}
+
+public class Pedido : AuditEntityBase // EntityBase + IAudit
+{
+    public virtual decimal Total { get; set; }
+}
+```
+
+Value objects herdam de `ValueObject` e comparam por todas as propriedades (não use `[DomainSignature]` neles — lança `InvalidOperationException`):
+
+```csharp
+using Codout.Framework.Domain.Base;
+
+public class Endereco : ValueObject
+{
+    public string Logradouro { get; set; }
+    public string Cidade { get; set; }
+    public string Cep { get; set; }
+}
+```
+
+As interfaces `IAudit`, `ISoftDeletable` (`DeletedAt`) e `ISequence` (`Code`) ficam em `Codout.Framework.Domain.Interfaces` e são reconhecidas pelas implementações de persistência do framework.

+
+## Instalação

+dotnet add package Codout.Framework.Storage.Azure
+```
+
+## Uso
+
+Registre via DI com um dos overloads de `AddAzureStorage` (por `IConfiguration` — lê a connection string `AzureStorage` —, por connection string, por `AzureStorageOptions` ou por `Action<AzureStorageOptions>`). O serviço é registrado como singleton de `IStorage`:
+
+```csharp
+using Microsoft.Extensions.DependencyInjection;
+
+var builder = WebApplication.CreateBuilder(args);
+
+// usa ConnectionStrings:AzureStorage do appsettings.json
+builder.Services.AddAzureStorage(builder.Configuration);
+
+// ou explicitamente:
+builder.Services.AddAzureStorage("UseDevelopmentStorage=true");
+```
+
+Consumindo `IStorage`:
+
+```csharp
+using Codout.Framework.Storage;
+
+public class DocumentoService(IStorage storage)
+{
+    public async Task<Uri> SalvarAsync(Stream arquivo, CancellationToken ct)
+    {
+        // upload (o content-type é inferido pela extensão do arquivo)

+    }
+}
+```
+
+Também é possível instanciar diretamente: `new AzureStorage(connectionString)` ou `new AzureStorage(new AzureStorageOptions { ConnectionString = "..." })`. Erros do Azure são encapsulados em `StorageException` (de Codout.Framework.Storage).

+Extensões para imagens baseadas em [SixLabors.ImageSharp](https://www.nuget.org/packages/SixLabors.ImageSharp): desenho de retângulos e pontos sobre imagens (ex.: marcação de faces e landmarks detectados) e extração/recorte de regiões com redimensionamento.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Image.Extensions
+```
+
+## Uso
+
+A classe `ImageExtensions` expõe métodos de extensão sobre `SixLabors.ImageSharp.Image`.
+
+Desenhar retângulos (mutação da imagem original) e pontos (retorna uma cópia):
+
+```csharp
+using Codout.Image.Extensions;
+using SixLabors.ImageSharp;
+using SixLabors.ImageSharp.Drawing.Processing;
+
+using var image = Image.Load("foto.jpg");
+var brush = Brushes.Solid(Color.Red);
+
+// Muta a imagem, desenhando os retângulos (espessura automática se omitida)
+image.DrawRectangles(brush, new[] { new Rectangle(50, 40, 120, 120) });
+
+// Retorna uma cópia com os pontos desenhados
+using var comPontos = image.DrawPoints(brush, new[] { new Point(80, 90), new Point(140, 95) });
+comPontos.Save("foto-marcada.jpg");
+```
+
+Extrair uma região da imagem, limitando o tamanho da maior aresta:
+
+```csharp
+using Codout.Image.Extensions;
+using SixLabors.ImageSharp;
+
+using var image = Image.Load("foto.jpg");
+
+// Recorte simples
+using var recorte = image.Extract(new Rectangle(50, 40, 300, 300));
+
+// Recorte com redução para no máximo 128px na maior aresta
+using var thumb = image.Extract(new Rectangle(50, 40, 300, 300), extractedMaxEdgeSize: 128);
+thumb.Save("thumb.jpg");
+```
+
+Há ainda `DrawRectanglesAndPoints` para desenhar retângulos (`RectangleF`) e pontos (`PointF`) de uma só vez, retornando uma cópia da imagem.

+# Codout.Mailer.AWS
+
+Dispatcher de e-mails via Amazon SES (Simple Email Service v2) para a biblioteca [Codout.Mailer](https://www.nuget.org/packages/Codout.Mailer), implementando `IMailerDispatcher` com a classe `AWSDispatcher`.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Mailer.AWS
+```
+
+Requer .NET 10 (`net10.0`).
+
+## Uso
+
+Registre o mailer com o dispatcher do SES usando a extensão `AddMailerWithAws` (que já chama `AddMailer` internamente e registra `AWSDispatcher` como `IMailerDispatcher`):
+
+```csharp
+using Codout.Mailer.AWS.Configuration;
+
+var builder = WebApplication.CreateBuilder(args);
+
+builder.Services.AddMailerWithAws(builder.Configuration);
+```
+
+Configure as credenciais no `appsettings.json`, na seção `AWSSettings` (classe `AWSSettings`, propriedades `RegionEndpoint`, `AccessKey` e `SecretKey` — todas obrigatórias):
+
+```json
+{
+  "MailerSettings": {
+    "DefaultFromName": "Minha Empresa",
+    "DefaultFromEmail": "noreply@minhaempresa.com"
+  },
+  "AWSSettings": {
+    "RegionEndpoint": "us-east-1",
+    "AccessKey": "sua-access-key",
+    "SecretKey": "sua-secret-key"
+  }
+}
+```
+
+O envio normalmente é feito por um serviço que herda de `MailerServiceBase` (veja o README do Codout.Mailer), mas o dispatcher também pode ser injetado e usado diretamente via `IMailerDispatcher.Send(from, to, subject, htmlContent, plainTextContent, attachments)`, que retorna um `MailerResponse` com `Sent` e `ErrorMessages`. Anexos (`System.Net.Mail.Attachment[]`) são montados via MimeKit e enviados como mensagem raw ao SES.

+# Codout.Mailer.Razor
+
+Implementação de `ITemplateEngine` para a biblioteca [Codout.Mailer](https://www.nuget.org/packages/Codout.Mailer) usando a engine Razor nativa do ASP.NET Core (classe `RazorViewTemplateEngine`), com templates embarcados como recursos do assembly.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Mailer.Razor
+```
+
+Requer .NET 10 (`net10.0`) e o framework `Microsoft.AspNetCore.App`.
+
+## Uso
+
+Registre o template engine com a extensão `AddMailerRazor`, depois de `AddMailer()` (ou de `AddMailerWithSendGrid`/`AddMailerWithAws`). As opções `TemplateAssembly` e `RootNamespace` de `RazorMailerOptions` são obrigatórias:
+
+```csharp
+using Codout.Mailer.Razor.Configuration;
+
+var builder = WebApplication.CreateBuilder(args);
+
+builder.Services.AddMailerWithSendGrid(builder.Configuration);
+
+builder.Services.AddMailerRazor(options =>
+{
+    options.TemplateAssembly = typeof(Program).Assembly;
+    options.RootNamespace = "MeuProjeto.Templates";
+    options.EnableCache = true; // padrão: true
+});
+```
+
+Os templates `.cshtml` devem ser embarcados no assembly indicado:
+
+```xml
+<ItemGroup>
+  <EmbeddedResource Include="Templates\*.cshtml" />
+</ItemGroup>
+```
+
+A renderização é feita por `RenderAsync<T>(string templateKey, T model)` — chamada automaticamente por `MailerServiceBase.Send`, mas também utilizável de forma direta:
+
+```csharp
+using Codout.Mailer.Interfaces;
+
+public class PreviaService(ITemplateEngine templateEngine)
+{
+    public Task<string> GerarHtmlAsync(BoasVindasModel model) =>
+        templateEngine.RenderAsync("BoasVindas", model);
+}
+```
+Se o template não for encontrado, é lançada `InvalidOperationException` listando os locais pesquisados.

+# Codout.Multitenancy
+
+Módulo de multitenancy para aplicações ASP.NET Core: resolve o tenant por requisição via middleware e expõe `IAppTenant`/`TenantContext` no container de DI com escopo de request.
+
+> **Softprime.Multitenancy**: a mesma pasta gera também o pacote `Softprime.Multitenancy`, um build `netstandard2.0` de compatibilidade com exatamente o mesmo código-fonte (o pacote principal `Codout.Multitenancy` tem target `net10.0`).
+
+## Instalação
+
+```bash
+dotnet add package Codout.Multitenancy
+```
+
+## Uso
+
+Implemente `ITenantResolver` (ou herde de `MemoryCacheTenantResolver` para ter cache em memória). O tenant resolvido deve implementar `IAppTenant` (`TenantKey`, `DataBaseType`, `ConnectionString`):
+
+```csharp
+using Codout.Multitenancy;
+using Microsoft.AspNetCore.Http;
+
+public class AppTenant : IAppTenant
+{
+    public string TenantKey { get; set; }
+    public DataBaseType DataBaseType { get; set; }
+    public string ConnectionString { get; set; }
+}
+
+public class HostTenantResolver : ITenantResolver
+{
+    public Task<TenantContext> ResolveAsync(HttpContext context)
+    {
+        var tenant = new AppTenant { TenantKey = context.Request.Host.Host };
+        return Task.FromResult(new TenantContext(tenant));
+    }
+}
+```
+
+Registre com `AddMultitenancy<TResolver>()` e ative o middleware com `UseMultitenancy()`:
+
+```csharp
+builder.Services.AddMultitenancy<HostTenantResolver>();
+
+var app = builder.Build();
+app.UseMultitenancy(); // antes dos endpoints que dependem do tenant
+```
+
+A partir daí, injete `IAppTenant` (ou `ITenant<IAppTenant>`/`TenantContext`) em serviços scoped, ou leia direto do request com `HttpContext.GetTenantContext()` / `HttpContext.GetTenant<AppTenant>()`.

+# Codout.Security.Argon2
+
+Implementação de `IPasswordHasher` (de [Codout.Security.Core](https://www.nuget.org/packages/Codout.Security.Core)) usando Argon2id via [Sodium.Core](https://www.nuget.org/packages/Sodium.Core) (libsodium).
+
+## Instalação
+
+```bash
+dotnet add package Codout.Security.Argon2
+```
+
+## Uso
+
+Registre o algoritmo no DI com o método de extensão `UseArgon2` (de `Argon2Extensions`), encadeado ao builder do Core. A força (`PasswordHasherStrength.Interactive`, `Moderate` ou `Sensitive`) controla CPU e memória usados pelo Argon2:
+
+```csharp
+using Codout.Security.Argon2;
+using Codout.Security.Core;
+
+builder.Services
+    .UpgradePasswordSecurity()
+    .WithStrength(PasswordHasherStrength.Sensitive)
+    .UseArgon2();
+```
+
+Para controle fino, configure `Argon2Options`. Quando `OpsLimit` e `MemLimit` (em bytes) são definidos juntos, eles sobrepõem o `Strength`:
+
+```csharp
+builder.Services
+    .UpgradePasswordSecurity()
+    .UseArgon2(options =>
+    {
+        options.OpsLimit = 4;                  // iterações (custo de CPU)
+        options.MemLimit = 256 * 1024 * 1024;  // 256 MiB de RAM
+    });
+```
+
+A implementação registrada é `ArgonPasswordHash` (scoped). `HashPassword` gera um hash no formato `$argon2id$...`; `VerifyHashedPassword` retorna `PasswordVerificationResult.SuccessRehashNeeded` quando o hash armazenado foi gerado com parâmetros (`m`/`t`) inferiores aos atualmente configurados, permitindo upgrade transparente dos hashes.

+```
+
+A implementação registrada é `BcryptPasswordHash` (scoped). `VerifyHashedPassword` retorna `PasswordVerificationResult.SuccessRehashNeeded` quando o hash armazenado usa `WorkFactor` menor que o configurado, permitindo upgrade transparente dos hashes existentes.

+# Codout.Security.Core
+
+Abstrações para hashing de senhas (`IPasswordHasher`, `IPasswordHashBuilder`) com integração ao container de DI do .NET — o algoritmo concreto (Argon2, Bcrypt ou Scrypt) é plugado por um pacote irmão.
+
+## Instalação
+
+```bash
+dotnet add package Codout.Security.Core
+```
+
+Este pacote contém apenas as abstrações. Instale também um dos pacotes de algoritmo (veja "Pacotes relacionados") para registrar uma implementação de `IPasswordHasher`.
+
+## Uso
+
+Registre o builder no DI com `PasswordHasherServiceExtensions` e configure a força do hash com `WithStrength` (enum `PasswordHasherStrength`: `Interactive`, `Moderate` ou `Sensitive`). Em seguida, encadeie o método `Use*` do pacote de algoritmo escolhido:
+
+```csharp
+using Codout.Security.Core;
+using Codout.Security.Argon2; // ou .Bcrypt / .Scrypt
+
+builder.Services
+    .UpgradePasswordSecurity() // ou UseCustomHashPasswordBuilder()
+    .WithStrength(PasswordHasherStrength.Moderate)
+    .UseArgon2();
+```
+
+Consuma `IPasswordHasher` por injeção de dependência:
+
+```csharp
+using Codout.Security.Core;
+
+public class AccountService(IPasswordHasher hasher)
+{
+    public string Register(string password) => hasher.HashPassword(password);
+
+    public bool Login(string hashed, string provided)
+    {
+        var result = hasher.VerifyHashedPassword(hashed, provided);
+        // PasswordVerificationResult: Failed, Success ou SuccessRehashNeeded
+        return result != PasswordVerificationResult.Failed;
+    }
+}
+```
+
+Quando `VerifyHashedPassword` retorna `PasswordVerificationResult.SuccessRehashNeeded`, a senha está correta, mas foi gerada com parâmetros mais fracos que os atuais — re-hasheie e persista o novo hash.

+# Codout.Security.Scrypt
+
+Implementação de `IPasswordHasher` (de [Codout.Security.Core](https://www.nuget.org/packages/Codout.Security.Core)) usando Scrypt via [Sodium.Core](https://www.nuget.org/packages/Sodium.Core) (libsodium).
+
+## Instalação
+
+```bash
+dotnet add package Codout.Security.Scrypt
+```
+
+## Uso
+
+Registre o algoritmo no DI com o método de extensão `UseScrypt` (de `ScryptExtensions`), encadeado ao builder do Core. A força (`PasswordHasherStrength.Interactive`, `Moderate` ou `Sensitive`) controla CPU e memória usados pelo Scrypt:
+
+```csharp
+using Codout.Security.Core;
+using Codout.Security.Scrypt;
+
+builder.Services
+    .UpgradePasswordSecurity()
+    .WithStrength(PasswordHasherStrength.Moderate)
+    .UseScrypt();
+```
+
+Para controle fino, configure `ScryptOptions`. Quando `OpsLimit` e `MemLimit` (em bytes) são definidos juntos, eles sobrepõem o `Strength`:
+
+```csharp
+builder.Services
+    .UpgradePasswordSecurity()
+    .UseScrypt(options =>
+    {
+        options.OpsLimit = 524288;             // custo de CPU
+        options.MemLimit = 128 * 1024 * 1024;  // 128 MiB de RAM
+    });
+```
+
+A implementação registrada é `ScryptPasswordHash` (scoped). `HashPassword` gera um hash no formato `$7$...` (escrypt/libsodium); `VerifyHashedPassword` retorna `PasswordVerificationResult.SuccessRehashNeeded` quando o hash armazenado foi gerado com parâmetro `N` inferior ao atualmente configurado, permitindo upgrade transparente dos hashes.

 # Codout.Framework.Data
 
-**Abstrações de persistência ORM-agnostic para .NET 10**
+Abstrações de acesso a dados para .NET: repositório genérico (`IRepository<T>`), unidade de trabalho (`IUnitOfWork`), entidades (`IEntity`, `IEntity<TId>`), especificações (`ISpecification<T>`) e auditoria (`IAuditable`, `ISoftDeletable`), independentes do provedor de persistência.
 
-Este projeto define os contratos (interfaces) para implementação de padrões Repository e Unit of Work, independente de tecnologia de persistência.
-
-## ?? Objetivo
-
-Fornecer abstrações que podem ser implementadas por qualquer ORM:
-- ? Entity Framework Core ([`Codout.Framework.EF`](../Codout.Framework.EF/README.md))
-- ? NHibernate ([`Codout.Framework.NH`](../Codout.Framework.NH/README.md))
-- ? MongoDB ([`Codout.Framework.Mongo`](../Codout.Framework.Mongo/README.md))
-
-## ?? Instalação
+## Instalação
 
 ```bash
 dotnet add package Codout.Framework.Data
 ```
 
-## ??? Arquitetura
-
-### Contratos Principais
-
-#### IEntity / IEntity\<TId\>
-Define a base para todas as entidades do domínio.
-
-```csharp
-public interface IEntity
-{
-    IEnumerable<PropertyInfo> GetSignatureProperties();
-    bool IsTransient();
-}
-
-public interface IEntity<out TId> : IEntity
-{
-    TId Id { get; }
-}
-```
-
-#### IRepository\<T\>
-Define operações CRUD genéricas para entidades.
-
-```csharp
-public interface IRepository<T> : IDisposable where T : class, IEntity
-{
-    // Query Methods
-    IQueryable<T> All();
-    IQueryable<T> AllReadOnly();
-    IQueryable<T> Where(Expression<Func<T, bool>> predicate);
-    T Get(Expression<Func<T, bool>> predicate);
-    Task<T> GetAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default);
-    
-    // Auxiliary Methods (v10.0+)
-    Task<T> FirstOrDefaultAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default);
-    Task<bool> AnyAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default);
-    Task<int> CountAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default);
-    Task<List<T>> ToListAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default);
-    
-    // Command Methods
-    void Delete(T entity);
-    T Save(T entity);
-    void Update(T entity);
-    Task<T> SaveAsync(T entity, CancellationToken ct = default);
-    Task UpdateAsync(T entity, CancellationToken ct = default);
-    
-    // Paging
-    IQueryable<T> WherePaged(Expression<Func<T, bool>> predicate, out int total, int index = 0, int size = 50);
-    
-    // Includes
-    IQueryable<T> IncludeMany(params Expression<Func<T, object>>[] includes);
-}
-```
-
-#### IUnitOfWork
-Define o padrão Unit of Work para gerenciamento de transações.
+## Uso
 
-```csharp
-public interface IUnitOfWork : IDisposable, IAsyncDisposable
-{
-    // Transaction Management
-    void BeginTransaction();
-    void BeginTransaction(IsolationLevel isolationLevel);
-    Task BeginTransactionAsync(CancellationToken ct = default);
-    Task BeginTransactionAsync(IsolationLevel isolationLevel, CancellationToken ct = default);
-    
-    void Commit();
-    void Commit(IsolationLevel isolationLevel);
-    Task CommitAsync(CancellationToken ct = default);
-    
-    void Rollback();
-    Task RollbackAsync(CancellationToken ct = default);
-    
-    // Transaction Helpers
-    T InTransaction<T>(Func<T> work) where T : class, IEntity;
-    Task<T> InTransactionAsync<T>(Func<Task<T>> work, CancellationToken ct = default) where T : class, IEntity;
-}
-```
-
-### Specification Pattern (v10.0+)
-
-#### ISpecification\<T\>
-Define especificações reutilizáveis para consultas complexas.
+Defina suas entidades implementando `IEntity<TId>` e dependa apenas dos contratos:
 
 ```csharp
-public interface ISpecification<T> where T : class, IEntity
-{
-    Expression<Func<T, bool>>? Criteria { get; }
-    Func<IQueryable<T>, IOrderedQueryable<T>>? OrderBy { get; }
-    List<Expression<Func<T, object>>> Includes { get; }
-    List<string> IncludeStrings { get; }
-    int Take { get; }
-    int Skip { get; }
-    bool IsPagingEnabled { get; }
-    bool AsNoTracking { get; }
-}
-```
+using Codout.Framework.Data;
+using Codout.Framework.Data.Repository;
 
-**Exemplo de Uso:**
-```csharp
-public class ActiveProductsSpec : Specification<Product>
+public class ClienteService(IRepository<Cliente> repository, IUnitOfWork unitOfWork)
 {
-    public ActiveProductsSpec()
+    public async Task<Cliente> CriarAsync(string nome, CancellationToken ct)
     {
-        AddCriteria(p => p.IsActive && !p.IsDeleted);
-        ApplyOrderBy(q => q.OrderBy(p => p.Name));
-        AddInclude(p => p.Category);
-        ApplyNoTracking();
+        var cliente = await repository.SaveAsync(new Cliente { Nome = nome }, ct);
+        await unitOfWork.CommitAsync(ct);
+        return cliente;
     }
-}
-```
-
-### Auditing Interfaces (v10.0+)
-
-#### IAuditable
-Para entidades que precisam de auditoria automática.
-
-```csharp
-public interface IAuditable
-{
-    DateTime CreatedAt { get; set; }
-    string? CreatedBy { get; set; }
-    DateTime? UpdatedAt { get; set; }
-    string? UpdatedBy { get; set; }
-}
-```
-
-#### ISoftDeletable
-Para entidades com soft delete (exclusão lógica).
-
-```csharp
-public interface ISoftDeletable
-{
-    bool IsDeleted { get; set; }
-    DateTime? DeletedAt { get; set; }
-    string? DeletedBy { get; set; }
-}
-```
 
-#### ICurrentUserProvider
-Provider para obter o usuário atual.
-
-```csharp
-public interface ICurrentUserProvider
-{
-    string? GetCurrentUserId();
+    public Task<List<Cliente>> BuscarAsync(string nome, CancellationToken ct) =>
+        repository.ToListAsync(c => c.Nome.Contains(nome), ct);
 }
 ```
 
-**Exemplo de Implementação:**
-```csharp
-public class HttpContextUserProvider : ICurrentUserProvider
-{
-    private readonly IHttpContextAccessor _httpContextAccessor;
-    
-    public HttpContextUserProvider(IHttpContextAccessor httpContextAccessor)
-    {
-        _httpContextAccessor = httpContextAccessor;
-    }
-    
-    public string? GetCurrentUserId()
-    {
-        return _httpContextAccessor.HttpContext?.User?.FindFirst(ClaimTypes.NameIdentifier)?.Value;
-    }
-}
-```
-
-## ?? Implementando as Abstrações
-
-### Exemplo: Entity Framework Core
-
-```csharp
-public class EFRepository<T> : IRepository<T> where T : class, IEntity
-{
-    protected readonly DbContext Context;
-    protected DbSet<T> DbSet => Context.Set<T>();
-
-    public EFRepository(DbContext context)
-    {
-        Context = context;
-    }
-
-    public IQueryable<T> All() => DbSet;
-    
-    public async Task<T> GetAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default) =>
-        await DbSet.SingleOrDefaultAsync(predicate, ct);
-    
-    public async Task<bool> AnyAsync(Expression<Func<T, bool>> predicate, CancellationToken ct = default) =>
-        await DbSet.AnyAsync(predicate, ct);
-    
-    // ... implementar outros métodos
-}
-```
-
-### Exemplo: Unit of Work
-
-```csharp
-public class EFUnitOfWork : IUnitOfWork
-{
-    private readonly DbContext _context;
-    private IDbContextTransaction? _transaction;
-
-    public EFUnitOfWork(DbContext context)
-    {
-        _context = context;
-    }
-
-    public async Task BeginTransactionAsync(CancellationToken ct = default)
-    {
-        _transaction = await _context.Database.BeginTransactionAsync(ct);
-    }
-
-    public async Task CommitAsync(CancellationToken ct = default)
-    {
-        await _context.SaveChangesAsync(ct);

-### Unit of Work
-
-```csharp
-public class MyUnitOfWork : EFUnitOfWork<MyDbContext>
-{
-    public MyUnitOfWork(MyDbContext context) : base(context)
-    {
-    }
-}
-
-// Uso com async/await
-await using var uow = new MyUnitOfWork(context);
-await uow.BeginTransactionAsync(ct);
-
-try
-{
-    await repository.SaveAsync(product, ct);
-    await uow.CommitAsync(ct);
-}
-catch
-{
-    await uow.RollbackAsync(ct);
-    throw;
-}
-```
-
-### InTransaction Helper
-
-```csharp
-var product = await uow.InTransactionAsync(async () =>
-{
-    var newProduct = new Product { Name = "Test" };
-    await repository.SaveAsync(newProduct);
-    return newProduct;
-}, ct);
-```
-
-## 🎯 Specification Pattern
-
-### Criando Specifications
-
-```csharp
-using Codout.Framework.EF.Specifications;
-using Codout.Framework.Data.Specifications;
-
-public class ActiveProductsSpecification : Specification<Product>
-{
-    public ActiveProductsSpecification()
-    {
-        AddCriteria(p => p.IsActive && !p.IsDeleted);
-        ApplyOrderBy(q => q.OrderBy(p => p.Name));
-        AddInclude(p => p.Category);
-        ApplyNoTracking();
-    }
-}
-
-public class ProductsByCategorySpecification : Specification<Product>
-{
-    public ProductsByCategorySpecification(int categoryId, int page, int pageSize)
-    {
-        AddCriteria(p => p.CategoryId == categoryId);
-        ApplyOrderBy(q => q.OrderByDescending(p => p.CreatedAt));
-        AddInclude(p => p.Category);
-        AddInclude("Reviews"); // String-based include
-        ApplyPaging((page - 1) * pageSize, pageSize);
-    }
-}
-```
-
-### Usando Specifications
-
-```csharp
-var spec = new ActiveProductsSpecification();
-var products = await repository.ListAsync(spec, ct);
-
-var categorySpec = new ProductsByCategorySpecification(categoryId: 5, page: 1, pageSize: 20);
-var pagedProducts = await repository.ListAsync(categorySpec, ct);
-
-var count = await repository.CountAsync(spec, ct);
-var exists = await repository.AnyAsync(spec, ct);
-var first = await repository.FirstOrDefaultAsync(spec, ct);
-```
-
-## 🔍 Auditoria Automática
-
-### Implementar IAuditable
-
-```csharp
-using Codout.Framework.Data.Auditing;
-
-public class Product : IEntity, IAuditable
-{
-    public int Id { get; set; }
-    public string Name { get; set; } = string.Empty;
-    
-    // Auditoria automática - preenchido pelo interceptor
-    public DateTime CreatedAt { get; set; }
-    public string? CreatedBy { get; set; }
-    public DateTime? UpdatedAt { get; set; }
-    public string? UpdatedBy { get; set; }
-    
-    public bool IsTransient() => Id == 0;
-    public IEnumerable<PropertyInfo> GetSignatureProperties() => 
-        new[] { typeof(Product).GetProperty(nameof(Id))! };
-}
-```
-
-### Configurar Provider de Usuário
-
-```csharp
-using Codout.Framework.Data.Auditing;
-
-public class HttpContextUserProvider : ICurrentUserProvider
-{
-    private readonly IHttpContextAccessor _httpContextAccessor;
-    
-    public HttpContextUserProvider(IHttpContextAccessor httpContextAccessor)
-    {
-        _httpContextAccessor = httpContextAccessor;
-    }
-    
-    public string? GetCurrentUserId()
-    {
-        return _httpContextAccessor.HttpContext?.User?.FindFirst(ClaimTypes.NameIdentifier)?.Value;
-    }
-}
+using Codout.Framework.EF;
 
-// Registrar
-services.AddHttpContextAccessor();
-services.AddSingleton<ICurrentUserProvider, HttpContextUserProvider>();
-```
-
-## 🗑️ Soft Delete Automático
-
-```csharp
-using Codout.Framework.Data.Auditing;
-
-public class Product : IEntity, ISoftDeletable
-{
-    public int Id { get; set; }
-    public string Name { get; set; } = string.Empty;
-    
-    // Soft delete automático - preenchido pelo interceptor
-    public bool IsDeleted { get; set; }
-    public DateTime? DeletedAt { get; set; }
-    public string? DeletedBy { get; set; }
-    
-    public bool IsTransient() => Id == 0;
-    public IEnumerable<PropertyInfo> GetSignatureProperties() => 
-        new[] { typeof(Product).GetProperty(nameof(Id))! };
-}
-
-// Configurar no DbContext
-protected override void OnModelCreating(ModelBuilder modelBuilder)
-{
-    // Query filter global para excluir registros deletados
-    modelBuilder.Entity<Product>()
-        .HasQueryFilter(p => !p.IsDeleted);
-}
-```
-
-## 🔄 Operações com CancellationToken
-
-```csharp
-var cts = new CancellationTokenSource(TimeSpan.FromSeconds(30));
-
-// Métodos auxiliares com CancellationToken
-var product = await repository.GetAsync(p => p.Id == 1, cts.Token);
-var first = await repository.FirstOrDefaultAsync(p => p.IsActive, cts.Token);
-var count = await repository.CountAsync(p => p.IsActive, cts.Token);
-var exists = await repository.AnyAsync(p => p.Name == "Test", cts.Token);
-var list = await repository.ToListAsync(p => p.Price > 100, cts.Token);
-
-// Transações com CancellationToken
-await uow.BeginTransactionAsync(cts.Token);
-await uow.CommitAsync(cts.Token);
-await uow.RollbackAsync(cts.Token);
-```
-
-## 📊 Operações Avançadas
-
-### Include com Navigation Properties
-
-```csharp
-var products = repository
-    .IncludeMany(
-        p => p.Category,
-        p => p.Reviews
-    )
-    .Where(p => p.IsActive)
-    .ToList();
-
-// String-based includes
-var productsWithStrings = repository
-    .IncludeMany("Category", "Reviews.User")
-    .Where(p => p.IsActive)
-    .ToList();
-```
-
-### Paginação
-
-```csharp
-var products = repository.WherePaged(
-    predicate: p => p.IsActive,
-    out int total,
-    index: 0,
-    size: 20
-);
-
-Console.WriteLine($"Total: {total}, Current Page: {products.Count()}");
-```
-
-### Read-Only Queries
-
-```csharp
-// Melhor performance para queries read-only (AsNoTracking automático)
-var products = repository
-    .WhereReadOnly(p => p.CategoryId == 1)
-    .ToList();
-
-var allReadOnly = repository.AllReadOnly();
-```
-
-### Operações CRUD Completas
-
-```csharp
-// Save
-var saved = await repository.SaveAsync(product, ct);
-
-// Update
-await repository.UpdateAsync(product, ct);
-
-// SaveOrUpdate (detecta se é novo ou existente)
-var savedOrUpdated = await repository.SaveOrUpdateAsync(product, ct);
-
-// Delete
-await repository.DeleteAsync(product, ct);
-
-// Delete com predicate
-await repository.DeleteAsync(p => p.IsActive == false, ct);
-
-// Merge (reattach detached entity)
-var merged = await repository.MergeAsync(product, ct);
-
-// Refresh (reload from database)
-var refreshed = await repository.RefreshAsync(product, ct);
-```

-## 🎓 Melhores Práticas
-
-1. **Use CancellationToken** em todas operações async
-2. **Use Specifications** para queries complexas reutilizáveis
-3. **Evite expor IQueryable** fora da camada de dados
-4. **Use AsNoTracking** para queries read-only (via `WhereReadOnly`)
-5. **Implemente IAuditable** para auditoria automática
-6. **Use ISoftDeletable** em vez de delete físico
-7. **Configure retry policies** para resiliência
-8. **Use scoped lifetime** para DbContext (padrão)
-9. **Configure query filters** no DbContext para soft delete
-10. **Use `WithConnectionStringFromConfiguration`** para ambientes diferentes
-11. **Use `await using`** para dispose automático do UnitOfWork
-12. **Trate exceções** apropriadamente em transações
-
-## 📝 Breaking Changes
-
-### Migração do Método Legado
-
-```csharp
-// ❌ Legado (deprecated)
-services.AddEFCore<MyDbContext>(configuration);
-
-// ✅ Novo (recomendado)
-services.AddEFCore<MyDbContext>(configuration)
-    .WithConnectionStringFromConfiguration()
+builder.Services
+    .AddEFCore<MeuDbContext>(builder.Configuration)
+    .WithConnectionStringFromConfiguration("DefaultConnection")
     .UseSqlServer()
+    .EnableRetryOnFailure()
     .Build();
 ```
 
-### Interfaces Movidas
+Use `EFRepository<T>` e uma especialização de `EFUnitOfWork<T>` (classe abstrata):
 
 ```csharp
-// ❌ Antes
-using Codout.Framework.EF.Interceptors;
+public class MeuUnitOfWork(MeuDbContext context) : EFUnitOfWork<MeuDbContext>(context);
 
-// ✅ Agora (interfaces no projeto base)
-using Codout.Framework.Data.Auditing;
-
-public class Product : IAuditable, ISoftDeletable { }
+var repository = new EFRepository<Cliente>(context);
+var cliente = await repository.SaveAsync(new Cliente { Nome = "Maria" }, ct);
+await unitOfWork.CommitAsync(ct); // chama SaveChanges e confirma a transação
 ```

-
-### Repository
-
-```csharp

-{
-    public ProductRepository(MongoDbContext context) : base(context)
-    {
-    }
-

-    {
-        return await CountAsync(p => p.IsActive, ct);
-    }
-}
-```
-
-### Unit of Work (com Transações)
-
-```csharp
-public class ProductService
-{
-    private readonly MongoRepository<Product> _repository;
-    private readonly IUnitOfWork _unitOfWork;
-
-    public async Task<Product> CreateProductAsync(Product product, CancellationToken ct = default)

-    await _repository.SaveAsync(newProduct, ct);
-    return newProduct;
-}, ct);
-```
-
-## ?? Operações Disponíveis
-
-### Query Methods
-
-```csharp
-// Todos os registros
-var all = repository.All();
-
-// Com filtro
-var active = repository.Where(p => p.IsActive);
-
-// Read-only (mesma performance no MongoDB)
-var readOnly = repository.AllReadOnly();
-
-// Paginação
-var paged = repository.WherePaged(p => p.IsActive, out int total, index: 0, size: 20);
-
-// Get único
-var product = await repository.GetAsync(p => p.Id == id, ct);
-
-// FirstOrDefault
-var first = await repository.FirstOrDefaultAsync(p => p.IsActive, ct);
-
-// Any
-var exists = await repository.AnyAsync(p => p.Name == "Test", ct);
-
-// Count
-var count = await repository.CountAsync(p => p.IsActive, ct);
-
-// ToList
-var list = await repository.ToListAsync(p => p.Price > 100, ct);
-
-// Load/Get por ID
-var byId = await repository.GetAsync(objectId, ct);
-var loaded = await repository.LoadAsync(objectId, ct); // Alias de GetAsync
-```
-
-### Command Methods
-
-```csharp
-// Salvar (Insert)
-await repository.SaveAsync(product, ct);
-
-// Atualizar (Replace)
-await repository.UpdateAsync(product, ct);
-
-// SaveOrUpdate (insert se novo, replace se existente)
-await repository.SaveOrUpdateAsync(product, ct);
-
-// Deletar
-await repository.DeleteAsync(product, ct);
-
-// Deletar com filtro
-await repository.DeleteAsync(p => p.IsActive == false, ct);
-
-// Merge (reattach - MongoDB usa ReplaceOne)
-var merged = await repository.MergeAsync(product, ct);
-
-// Refresh (re-carregar do banco)
-var refreshed = await repository.RefreshAsync(product, ct);
-```
-
-## ?? Limitações do MongoDB
-
-### 1. Includes (Relacionamentos)
+## Uso
 
-MongoDB não suporta `Include` nativo como EF Core:
+Registre os serviços com `AddMongoDb`, que configura `IMongoClient`, `IMongoDatabase` e `IRepository<T>` no container de DI:
 
 ```csharp
-// ? Não funciona como esperado
-var products = repository.IncludeMany(p => p.Category);
-
-// ? Use agregações ou lookups do MongoDB
-var collection = context.GetCollection<Product>();
-var productsWithCategory = await collection.Aggregate()
-    .Lookup("categories", "categoryId", "_id", "category")
-    .ToListAsync(ct);
-```
-
-### 2. Transações
+using Codout.Framework.Mongo.Configuration;
 
-Transações requerem replica set:
-
-```bash
-# Configurar replica set local (desenvolvimento)
-mongod --replSet rs0 --port 27017 --dbpath /data/db1
-
-# Inicializar replica set
-mongosh
-> rs.initiate()
+builder.Services.AddMongoDb(
+    connectionString: "mongodb://localhost:27017",
+    databaseName: "minha-base");
 ```
 
-### 3. IQueryable Limitado
-
-O driver MongoDB suporta LINQ, mas não todos os operadores:
+Injete `IRepository<T>` ou instancie `MongoRepository<T>` diretamente:
 
 ```csharp
-// ? Funciona
-var products = repository.Where(p => p.Price > 100 && p.IsActive);
-
-// ?? Pode não funcionar
-var products = repository.Where(p => p.Name.StartsWith("A") || p.Name.EndsWith("Z"));
-
-// ? Alternativa: usar filtros do MongoDB
-var filter = Builders<Product>.Filter.Or(
-    Builders<Product>.Filter.Regex("name", new BsonRegularExpression("^A")),
-    Builders<Product>.Filter.Regex("name", new BsonRegularExpression("Z$"))
-);
-```
-
-## ?? Operações com CancellationToken
-
-```csharp
-var cts = new CancellationTokenSource(TimeSpan.FromSeconds(30));
-
-try
-{
-    var product = await repository.GetAsync(p => p.Id == id, cts.Token);
-    await repository.UpdateAsync(product, cts.Token);
-    await unitOfWork.CommitAsync(cts.Token);
-}
-catch (OperationCanceledException)
-{
-    Console.WriteLine("Operação cancelada pelo timeout");
-}
-```
-
-## ??? Arquitetura Recomendada
-
-```
-?? MyProject.Data.Mongo
-??? ?? Context
-?   ??? MyMongoContext.cs (se precisar estender)
-??? ?? Repositories
-?   ??? IProductRepository.cs
-?   ??? ProductRepository.cs
-??? ?? Entities
-    ??? Product.cs
-```
-
-## ?? Melhores Práticas
-
-1. **Use ObjectId para IDs**: MongoDB funciona melhor com ObjectId
-2. **Configure índices**: Use atributos `[BsonIndex]` ou configure via código
-3. **Use CancellationToken**: Sempre em operações async
-4. **Transações apenas quando necessário**: Têm overhead de performance
-5. **Evite queries muito complexas**: Use agregações do MongoDB diretamente
-6. **Configure Write Concern**: Para garantir persistência em replica set
-7. **Use await using**: Para dispose automático do UnitOfWork
-8. **Valide ObjectId**: Antes de fazer queries por ID
-
-## ?? Índices
-
-```csharp
-// Via código na configuração
-var collection = database.GetCollection<Product>("products");
-
-var indexKeysDefinition = Builders<Product>.IndexKeys
-    .Ascending(p => p.Name)
-    .Descending(p => p.Price);
+using Codout.Framework.Mongo;
 
-await collection.Indexes.CreateOneAsync(
-    new CreateIndexModel<Product>(indexKeysDefinition),
-    cancellationToken: ct
-);
+var repository = new MongoRepository<Cliente>(database); // IMongoDatabase
+var cliente = await repository.SaveAsync(new Cliente { Nome = "Maria" }, ct);
+var ativos = await repository.ToListAsync(c => c.Ativo, ct);

+## Uso
 
-### Program.cs com FluentNHibernate
+Registre os serviços com `AddNHibernateServices`, que configura `ISessionFactory` (singleton), `ISession` e `IStatelessSession` (scoped) e o ciclo de vida da fábrica:
 
 ```csharp
 using Codout.Framework.NH;
-using Codout.Framework.Data;
-using FluentNHibernate.Cfg;
-using FluentNHibernate.Cfg.Db;
-using NHibernate;
-using NHibernate.Tool.hbm2ddl;
-
-// Configurar NHibernate Session Factory
-services.AddSingleton<ISessionFactory>(sp =>
-{
-    var connectionString = configuration.GetConnectionString("DefaultConnection");
-    
-    return Fluently.Configure()
-        .Database(MsSqlConfiguration.MsSql2012
-            .ConnectionString(connectionString)
-            .ShowSql())
-        .Mappings(m => m.FluentMappings
-            .AddFromAssemblyOf<Product>())
-        .ExposeConfiguration(cfg => new SchemaUpdate(cfg).Execute(false, true))
-        .BuildSessionFactory();
-});
-
-// Configurar Session (scoped)
-services.AddScoped<ISession>(sp =>
-{
-    var factory = sp.GetRequiredService<ISessionFactory>();
-    return factory.OpenSession();
-});
-
-// Configurar Unit of Work
-services.AddScoped<IUnitOfWork, NHUnitOfWork>();
-```
-
-## ?? Uso Básico
-
-### Entidades
-
-```csharp
-using Codout.Framework.Data.Entity;
-using System.Reflection;
-
-public class Product : IEntity
-{
-    public virtual int Id { get; set; }
-    public virtual string Name { get; set; } = string.Empty;
-    public virtual decimal Price { get; set; }
-    public virtual bool IsActive { get; set; }
-    public virtual Category? Category { get; set; }
-    
-    public bool IsTransient() => Id == 0;
-    
-    public IEnumerable<PropertyInfo> GetSignatureProperties()
-    {
-        return new[] { typeof(Product).GetProperty(nameof(Id))! };
-    }
-}
-```
-
-**Importante**: Propriedades **devem ser virtual** para permitir lazy loading e proxies do NHibernate.
-
-### Mapeamento FluentNHibernate
-
-```csharp
-using FluentNHibernate.Mapping;
-
-public class ProductMap : ClassMap<Product>
-{
-    public ProductMap()
-    {
-        Table("Products");
-        
-        Id(x => x.Id).GeneratedBy.Identity();
-        
-        Map(x => x.Name).Not.Nullable().Length(200);
-        Map(x => x.Price).Not.Nullable();
-        Map(x => x.IsActive).Not.Nullable();
-        
-        References(x => x.Category)
-            .Column("CategoryId")
-            .LazyLoad();
-    }
-}
-```
-
-### Repository
-
-```csharp
-public class ProductRepository : NHRepository<Product>
-{
-    public ProductRepository(IUnitOfWork unitOfWork) : base(unitOfWork)
-    {
-    }
-    
-    public async Task<List<Product>> GetActiveProductsAsync(CancellationToken ct = default)
-    {
-        return await ToListAsync(p => p.IsActive, ct);
-    }
-    
-    public async Task<bool> HasActiveProductsAsync(CancellationToken ct = default)

-    
-    public async Task<int> CountActiveProductsAsync(CancellationToken ct = default)
-    {
-        return await CountAsync(p => p.IsActive, ct);
-    }
-}
-```
-
-### Unit of Work (com Transações)
-
-```csharp
-public class ProductService
-{
-    private readonly NHRepository<Product> _repository;
-    private readonly IUnitOfWork _unitOfWork;
-
-    public async Task<Product> CreateProductAsync(Product product, CancellationToken ct = default)
-    {
-        await _unitOfWork.BeginTransactionAsync(ct);
-        
-        try
-        {
-            await _repository.SaveAsync(product, ct);
-            await _unitOfWork.CommitAsync(ct);

-```csharp
-var product = await _unitOfWork.InTransactionAsync(async () =>
-{
-    var newProduct = new Product { Name = "Test", Price = 100 };
-    await _repository.SaveAsync(newProduct, ct);
-    return newProduct;
-}, ct);
-```
-
-## ?? Operações Disponíveis
-
-### Query Methods
-

-// Refresh (re-carregar do banco)
-var refreshed = await repository.RefreshAsync(product, ct);
+builder.Services.AddNHibernateServices(builder.Configuration);
 ```
 
-## ?? Eager Loading
+Os assemblies de mapeamento são lidos da seção de configuração `NHibernate:MappingAssemblies` (array de nomes de assembly).
 
-### NHibernate não suporta Include como EF Core
+Use `NHRepository<T>`, que recebe um `ISession` no construtor:
 
 ```csharp
-// ? Não funciona
-var products = repository.IncludeMany(p => p.Category);
-
-// ? Use Fetch no LINQ
-var products = repository.All()
-    .Fetch(p => p.Category)
-    .ThenFetch(c => c.Supplier)
-    .ToList();
-
-// ? Ou configure no mapeamento
-public class ProductMap : ClassMap<Product>
-{
-    public ProductMap()
-    {
-        References(x => x.Category)
-            .Not.LazyLoad(); // Eager load sempre
-    }
-}
-
-// ? Ou use FetchMode em queries
-var session = ((NHRepository<Product>)repository).Session;
-var products = session.CreateCriteria<Product>()
-    .SetFetchMode("Category", FetchMode.Eager)
-    .List<Product>();
-```
-

-
-```csharp
-public class ProductMap : ClassMap<Product>
-{
-    public ProductMap()
-    {
-        Table("Products");
-        
-        Id(x => x.Id).GeneratedBy.Identity();
-        
-        // Many-to-One
-        References(x => x.Category)
-            .Column("CategoryId")
-            .LazyLoad()
-            .Cascade.None();
-        
-        // One-to-Many
-        HasMany(x => x.Reviews)
-            .KeyColumn("ProductId")
-            .Inverse()
-            .Cascade.AllDeleteOrphan();
-    }
-}
-```
-
-### Componentes
-
-```csharp
-public class ProductMap : ClassMap<Product>
-{
-    public ProductMap()
-    {
-        Component(x => x.Address, m =>
-        {
-            m.Map(x => x.Street).Column("Street");
-            m.Map(x => x.City).Column("City");
-            m.Map(x => x.ZipCode).Column("ZipCode");
-        });
-    }
-}
-```
-
-## ?? Session Management
-
-### Acesso direto à Session
-
-```csharp
-public class ProductRepository : NHRepository<Product>
-{
-    public async Task<List<Product>> GetProductsWithCustomQuery(CancellationToken ct = default)
-    {
-        return await Session
-            .CreateQuery("FROM Product p WHERE p.Price > 100")
-            .ListAsync<Product>(ct);
-    }
-    
-    public async Task BulkUpdateAsync(CancellationToken ct = default)
-    {
-        await Session
-            .CreateQuery("UPDATE Product SET IsActive = false WHERE Price < 10")
-            .ExecuteUpdateAsync(ct);
-    }
-}
-```
-
-## ?? Considerações NHibernate
-
-### 1. Propriedades Virtuais
-
-```csharp
-// ? Correto - permite lazy loading
-public class Product
-{
-    public virtual int Id { get; set; }
-    public virtual string Name { get; set; }
-    public virtual Category Category { get; set; }
-}
-
-// ? Errado - não permite lazy loading
-public class Product
-{
-    public int Id { get; set; }
-    public string Name { get; set; }
-}
-```
-
-### 2. Flush vs Commit
-
-```csharp
-// Flush persiste no banco mas não comita a transação
-await Session.FlushAsync(ct);
-
-// Commit faz flush + commit da transação
-await unitOfWork.CommitAsync(ct);
-```
-
-### 3. Detached Entities
-
-```csharp
-// Entity fora do contexto (detached)
-var product = new Product { Id = 1, Name = "Updated" };
-
-// ? Update falha se detached
-await repository.UpdateAsync(product, ct);
-
-// ? Use Merge para reattach
-var merged = await repository.MergeAsync(product, ct);
-await repository.UpdateAsync(merged, ct);
-```
-
-### 4. Load vs Get
-
-```csharp
-// Load - retorna proxy, lança exceção se não existir quando acessado
-var proxy = repository.Load(id); // Não acessa o banco ainda
-var name = proxy.Name; // Acessa o banco aqui
-
-// Get - retorna null se não existir
-var product = await repository.GetAsync(id, ct); // Acessa o banco imediatamente
-if (product == null) { /* não existe */ }
-```
-
-## ?? Operações com CancellationToken
-
-```csharp
-var cts = new CancellationTokenSource(TimeSpan.FromSeconds(30));
-
-try
-{
-    var product = await repository.GetAsync(p => p.Id == id, cts.Token);
-    await repository.UpdateAsync(product, cts.Token);
-    await unitOfWork.CommitAsync(cts.Token);
-}
-catch (OperationCanceledException)
-{
-    Console.WriteLine("Operação cancelada pelo timeout");
-}
-```
-
-## ?? Melhores Práticas
-
-1. **Use propriedades virtual**: Permite lazy loading e proxies
-2. **Configure Cascade corretamente**: Evite orphan deletions acidentais
-3. **Use CancellationToken**: Sempre em operações async
-4. **Flush antes de queries**: Se precisar dos dados persistidos
-5. **Evite N+1**: Use Fetch/FetchMany para eager loading
-6. **Configure índices**: No banco ou via atributos
-7. **Use Stateless Session**: Para operações batch de alto volume
-8. **Use await using**: Para dispose automático do UnitOfWork
-9. **Evite lazy loading em loops**: Carregue dados antecipadamente
-10. **Configure cache de segundo nível**: Para performance
-
-## ?? Índices
+using Codout.Framework.NH;
 
-```csharp
-public class ProductMap : ClassMap<Product>
-{
-    public ProductMap()
-    {
-        // Índice único
-        Map(x => x.Name)
-            .Not.Nullable()
-            .Length(200)
-            .UniqueKey("UK_Product_Name");
-        
-        // Índice composto
-        Map(x => x.CategoryId).Index("IX_Product_Category_Active");
-        Map(x => x.IsActive).Index("IX_Product_Category_Active");
-    }
-}
+var repository = new NHRepository<Cliente>(session); // ISession
+var cliente = await repository.SaveAsync(new Cliente { Nome = "Maria" }, ct);
+var ativos = await repository.ToListAsync(c => c.Ativo, ct);

+await storage.DeleteAsync("documentos", "contrato.pdf", ct);
 ```
 
-## ?? Melhores Práticas
-
-1. **Use CancellationToken** em todas operações async
-2. **Use GetStreamAsync** em vez de DownloadAsync para arquivos grandes (streaming)
-3. **Implemente retry logic** para operações críticas
-4. **Use SAS tokens** para acesso temporário em vez de URLs públicas
-5. **Configure CDN** para melhor performance de leitura
-6. **Use metadata** para armazenar informações contextuais
-7. **Valide nomes de arquivos** antes do upload
-8. **Implemente progress reporting** para uploads grandes
-9. **Use batch operations** para deletar múltiplos arquivos
-10. **Trate exceções específicas** (`StorageNotFoundException`, etc.)
-
-## ?? Novidades v10.0
-
-- ? **Nova interface IStorage** com naming convention async
-- ? **Metadata support** completo
-- ? **SAS tokens** para acesso temporário
-- ? **List operations** com prefixo
-- ? **Batch delete** para múltiplos arquivos
-- ? **Progress reporting** em uploads
-- ? **Exceções customizadas** tipadas
-- ? **CDN support** integrado
-- ? **Thread-safe** lazy loading
-- ? **Extensões DI** fluentes
-- ? **Nullable reference types**

+## Instalação
 
-## 📦 Installation
-
-### Main Package
-```
+```bash
 dotnet add package Codout.Mailer
 ```
 
-### Razor Template Engine
-```
-dotnet add package Codout.Mailer.Razor
-```
+## Uso
 
-### Specific Providers
-```
-# For SendGrid
-dotnet add package Codout.Mailer.SendGrid
-
-# For AWS SES
-dotnet add package Codout.Mailer.AWS
-```
-
-## ⚙️ Configuration
-
-### 1. **Dependency Injection in Program.cs**
+Registre as configurações com `AddMailer` (lê a seção `MailerSettings`, com `DefaultFromName` e `DefaultFromEmail`):
 
 ```csharp
-var builder = WebApplication.CreateBuilder(args);
+using Codout.Mailer.Configuration;
 
-// Basic mailer configuration
 builder.Services.AddMailer(builder.Configuration);
-
-// Razor template engine (uses ASP.NET Core's native Razor engine)
-builder.Services.AddMailerRazor(options =>
-{
-    options.TemplateAssembly = typeof(Program).Assembly;
-    options.RootNamespace = "YourProject.Templates";
-});
-
-// Choose email provider
-builder.Services.AddMailerWithSendGrid(builder.Configuration);
-// OR
-// builder.Services.AddMailerWithAws(builder.Configuration);
-
-// Register your custom email service
-builder.Services.AddScoped<EmailService>();
-
-var app = builder.Build();
-```
-
-### 2. **Settings in appsettings.json**
-
-```json
-{
-  "MailerSettings": {
-    "DefaultFromName": "Email System",
-    "DefaultFromEmail": "noreply@example.com"
-  },
-  "SendGridSettings": {
-    "ApiKey": "SG.your-api-key-here",
-    "SandboxMode": false
-  },
-  "AWSSettings": {
-    "RegionEndpoint": "us-east-1",
-    "AccessKey": "your-access-key",
-    "SecretKey": "your-secret-key"
-  }
-}
 ```
 
-## 🏗️ Implementation in Your Project
-
-### 1. **Creating Your EmailService Class**
-
-Create a class that inherits from `MailerServiceBase` in your project:
+Crie seu serviço herdando de `MailerServiceBase`, que renderiza o template via `ITemplateEngine`, converte o HTML em texto plano e envia pelo `IMailerDispatcher` registrado:
 
 ```csharp
-// Services/EmailService.cs
-using System.Net.Mail;
-using System.Threading.Tasks;
-using Codout.Mailer.Configuration;
-using Codout.Mailer.Interfaces;
 using Codout.Mailer.Models;
 using Codout.Mailer.Services;
-using Microsoft.Extensions.Logging;
-using Microsoft.Extensions.Options;
-using YourProject.Models.Email;
-
-public class EmailService : MailerServiceBase
-{
-    public EmailService(
-        IOptions<MailerSettings> mailerSettings,
-        IMailerDispatcher dispatcher,
-        ITemplateEngine templateEngine,
-        ILogger<EmailService> logger)
-        : base(mailerSettings, dispatcher, templateEngine, logger)
-    {
-    }
-
-    /// <summary>
-    /// Sends welcome email to new users
-    /// </summary>
-    public async Task<MailerResponse> Welcome(WelcomeModel model)
-    {
-        return await Send("Welcome", model, "Welcome to our platform!");
-    }
-
-    /// <summary>
-    /// Sends password reset email
-    /// </summary>
-    public async Task<MailerResponse> PasswordReset(PasswordResetModel model)
-    {
-        return await Send("PasswordReset", model, "Password Recovery");
-    }
-
-    /// <summary>
-    /// Sends registration confirmation email
-    /// </summary>
-    public async Task<MailerResponse> ConfirmRegistration(ConfirmRegistrationModel model)
-    {
-        return await Send("ConfirmRegistration", model, "Confirm your registration");
-    }
-
-    /// <summary>
-    /// Sends order notification email
-    /// </summary>
-    public async Task<MailerResponse> OrderNotification(OrderNotificationModel model)
-    {
-        return await Send("OrderNotification", model, $"Order #{model.OrderNumber} - Status Updated");
-    }
-
-    /// <summary>
-    /// Sends monthly report with attachment
-    /// </summary>
-    public async Task<MailerResponse> MonthlyReport(MonthlyReportModel model, Attachment[] attachments = null)
-    {
-        return await Send("MonthlyReport", model, $"Monthly Report - {model.Month:MMMM yyyy}", attachments);
-    }
-}
-```
-
-### 2. **Creating Email Models**
-
-Create a `Models/Email` folder and add models for each email type:
-
-```csharp
-// Models/Email/WelcomeModel.cs
-using System.Net.Mail;
-using Codout.Mailer.Models;
-
-namespace YourProject.Models.Email;
-
-public class WelcomeModel : MailerModelBase
-{
-    public string Name { get; set; }
-    public string ActivationLink { get; set; }
-    public string CompanyName { get; set; } = "My Company";
-    public string SupportEmail { get; set; } = "support@mycompany.com";
-}
-```
-
-```csharp
-// Models/Email/PasswordResetModel.cs
-using System.Net.Mail;
-using Codout.Mailer.Models;
-
-namespace YourProject.Models.Email;
-
-public class PasswordResetModel : MailerModelBase
-{
-    public string Name { get; set; }
-    public string ResetLink { get; set; }
-    public DateTime ExpiresAt { get; set; }
-    public string IpAddress { get; set; }
-}
-```
-
-```csharp
-// Models/Email/ConfirmRegistrationModel.cs
-using System.Net.Mail;
-using Codout.Mailer.Models;
-
-namespace YourProject.Models.Email;
-
-public class ConfirmRegistrationModel : MailerModelBase
-{
-    public string Name { get; set; }
-    public string ConfirmationLink { get; set; }
-    public string Username { get; set; }
-}
-```
-
-```csharp
-// Models/Email/OrderNotificationModel.cs
-using System.Net.Mail;
-using Codout.Mailer.Models;
-
-namespace YourProject.Models.Email;
-
-public class OrderNotificationModel : MailerModelBase
-{
-    public string CustomerName { get; set; }
-    public string OrderNumber { get; set; }
-    public string Status { get; set; }
-    public decimal TotalAmount { get; set; }
-    public DateTime OrderDate { get; set; }
-    public List<OrderItemModel> Items { get; set; } = new();
-    public string TrackingUrl { get; set; }
-}
-
-public class OrderItemModel
-{
-    public string ProductName { get; set; }
-    public int Quantity { get; set; }
-    public decimal Price { get; set; }
-}
-```
-
-```csharp
-// Models/Email/MonthlyReportModel.cs
-using System.Net.Mail;
-using Codout.Mailer.Models;
-
-namespace YourProject.Models.Email;
-
-public class MonthlyReportModel : MailerModelBase
-{
-    public string Name { get; set; }
-    public DateTime Month { get; set; }
-    public int TotalOrders { get; set; }
-    public decimal TotalRevenue { get; set; }
-    public string ReportType { get; set; }
-    public List<string> Highlights { get; set; } = new();
-}

-## 🎯 Using in Controllers
-
-### 1. **Controller Injection**
-
-```csharp
-[ApiController]
-[Route("api/[controller]")]
-public class UserController : ControllerBase
-{
-    private readonly EmailService _emailService;
-    private readonly ILogger<UserController> _logger;
+public class MeuMailerService(
+    IOptions<MailerSettings> settings,
+    IMailerDispatcher dispatcher,
+    ITemplateEngine templateEngine,
+    ILogger<MailerServiceBase> logger)
+    : MailerServiceBase(settings, dispatcher, templateEngine, logger);
 
-    public UserController(EmailService emailService, ILogger<UserController> logger)
-    {
-        _emailService = emailService;
-        _logger = logger;
-    }
-}
-```
-
-### 2. **Sending Emails**
-
-```csharp
-[HttpPost("register")]
-public async Task<IActionResult> Register([FromBody] RegisterRequest request)
-{
-    // User registration logic...
-    
-    try

-    }
-}
-
-[HttpPost("forgot-password")]
-public async Task<IActionResult> ForgotPassword([FromBody] ForgotPasswordRequest request)
-{

-
-```xml
-<Project Sdk="Microsoft.NET.Sdk.Web">
-
-  <PropertyGroup>
-    <TargetFramework>net10.0</TargetFramework>
-  </PropertyGroup>
-
-  <ItemGroup>
-    <EmbeddedResource Include="Templates\*.cshtml" />
-  </ItemGroup>
-
-</Project>
+MailerResponse resposta = await mailerService.Send("BoasVindas", model, "Bem-vindo!");
 ```
 
-## 🚀 Complete Usage Example
-
-```csharp
-// Program.cs
-var builder = WebApplication.CreateBuilder(args);
-
-// Mailer configuration
-builder.Services.AddMailer(builder.Configuration);

-    options.TemplateAssembly = typeof(Program).Assembly;
-    options.RootNamespace = "YourProject.Templates";
-    options.EnableCache = true; // Enables compiled template caching (default: true)
-});
-```
-
-### **Custom Template Engine**
-
-You can implement `ITemplateEngine` to use any template engine of your choice:
-
-```csharp
-public class MyCustomTemplateEngine : ITemplateEngine
-{
-    public async Task<string> RenderAsync<T>(string templateKey, T model)
-    {
-        // Your custom rendering logic
-    }
-}
-
-// Register in DI
-builder.Services.AddScoped<ITemplateEngine, MyCustomTemplateEngine>();
-```
-
-## 📊 Monitoring and Observability
-
-### **Health Checks**
-```csharp
-// Automatically added when using AddMailer()
-app.MapHealthChecks("/health");
-```
-
-### **Metrics and Tracing**
-The library automatically generates:
-- **Traces**: For each email send operation
-- **Metrics**: Counters for sent/failed emails
-- **Structured logs**: For debugging and auditing
-
-## 🚨 Error Handling
-
-```csharp
-try
-{
-    var response = await _emailService.Welcome(model);
-    
-    if (!response.Sent)
-    {
-        // Email was not sent
-        _logger.LogWarning("Send failure: {Errors}", 
-            string.Join(", ", response.ErrorMessages));
-    }
-}
-catch (TemplateNotFoundException ex)
-{
-    _logger.LogError("Template not found: {Template}", ex.TemplateName);
-}
-catch (EmailProviderException ex)
-{
-    _logger.LogError("Email provider error: {Error}", ex.Message);
-}
-catch (Exception ex)
-{
-    _logger.LogError(ex, "Unexpected error sending email");
-}
-```
-
-## 📋 Available Configurations
-
-### MailerSettings (appsettings.json)
-
-| Configuration | Description | Default |
-|-------------|-----------|--------|
-| `DefaultFromName` | Default sender name | `null` |
-| `DefaultFromEmail` | Default sender email | `null` |
-
-### RazorMailerOptions (Codout.Mailer.Razor)
-
-| Configuration | Description | Default |
-|-------------|-----------|--------|
-| `TemplateAssembly` | Assembly containing embedded Razor templates | `null` |
-| `RootNamespace` | Root namespace of embedded templates | `null` |
-| `EnableCache` | Enable compiled template caching | `true` |
-
-## 🔧 Tips and Best Practices
-
-### ✅ **Do's**
-- ✅ Always inherit from `MailerServiceBase` for your custom class
-- ✅ Create specific models inheriting from `MailerModelBase`
-- ✅ Use Razor templates organized in folders
-- ✅ Register a template engine via `AddMailerRazor()` or a custom `ITemplateEngine`
-- ✅ Handle exceptions when sending emails
-- ✅ Use logging for auditing
-
-### ❌ **Don'ts**
-- ❌ Don't use `IMailerService` directly in controllers
-- ❌ Don't forget to configure templates as Embedded Resources
-- ❌ Don't expose send errors to end users
-- ❌ Don't send emails without data validation
-
-## 📚 Next Steps
+Este pacote não envia e-mails sozinho: é necessário registrar uma implementação de `IMailerDispatcher` (provedor) e de `ITemplateEngine` (renderização de templates).
 
-1. **Advanced Templates**: Create responsive layouts
-2. **Internationalization**: Support for multiple languages
-3. **Email Queue**: Integration with background services
-4. **Analytics**: Open and click tracking

164 testes: CRUD/queries/async/UnitOfWork do MongoRepository contra
mongod efêmero real (skip gracioso se indisponível) e do NHRepository
contra SQLite via driver test-only. Bugs pré-existentes caracterizados
em tests/FINDINGS-D.md (WherePaged do Mongo com total errado, Rollback
fora da transação, DefaultReadOnly permanente no NH, etc.).

+# FINDINGS — suítes de teste NH / Mongo (sessão D)
+
+Achados registrados durante a criação das suítes `Codout.Framework.NH.Tests` e
+`Codout.Framework.Mongo.Tests`. Nenhum código de produção foi alterado; os
+comportamentos abaixo estão cobertos por testes de caracterização (marcados
+com `// BUG?:` quando aplicável).
+
+## Ambiente / decisões de infraestrutura
+
+- **Mongo — caminho adotado: EphemeralMongo FUNCIONOU.** O pacote
+  `EphemeralMongo 3.2.0` baixou e subiu o `mongod` neste ambiente Linux,
+  inclusive com `UseSingleNodeReplicaSet = true` (necessário para as
+  transações do `MongoUnitOfWork`). Os testes de integração rodaram de
+  verdade (0 skipped). A fixture (`tests/Codout.Framework.Mongo.Tests/TestInfrastructure.cs`)
+  continua resiliente: se o `mongod` não subir em outro ambiente, os testes de
+  integração (`[SkippableFact]`) são marcados como SKIPPED com a razão da
+  falha, e os testes de unidade (validação de opções, null-checks, nome de
+  coleção, DI) rodam sem servidor.
+- **NH — o NHibernate 5.6.0 NÃO possui `MicrosoftDataSqliteDriver`** embutido
+  (apenas `SQLite20Driver`, que reflete sobre `System.Data.SQLite`, e
+  `CsharpSqliteDriver`). Foi criado um driver **somente de teste**
+  (`MicrosoftDataSqliteTestDriver : ReflectionBasedDriver`) apontando para
+  `Microsoft.Data.Sqlite`.
+- **Microsoft.Data.Sqlite não implementa `GetSchema("DataTypes")`**, usado
+  pelo auto-import de keywords do NHibernate no build da SessionFactory
+  (`SchemaMetadataUpdater`). Os testes desligam isso com
+  `hbm2ddl.keywords = none`. Quem for usar o pacote `Codout.Framework.NH`
+  com Microsoft.Data.Sqlite em produção esbarra no mesmo problema.
+- SQLite `:memory:` não funciona com NHibernate na configuração padrão
+  (conexão é aberta/fechada por sessão e o banco evapora); os testes usam um
+  arquivo temporário por fixture.
+
+## Codout.Framework.Mongo
+
+- **`Codout.Framework.Mongo/MongoRepository.cs` — `WherePaged` retorna `total` errado.**
+  O `total` (out) é calculado **depois** de aplicar `Skip/Take`, ou seja,
+  devolve o tamanho da página (≤ `size`) e não o total de registros que
+  satisfazem o filtro. O `NHRepository.WherePaged` conta **antes** de paginar
+  (comportamento correto); um paginador construído sobre o `total` do Mongo
+  verá sempre "1 página". `// BUG?:` caracterizado em
+  `MongoRepositoryQueryTests.WherePaged_Caracterizacao_TotalRetornaTamanhoDaPaginaENaoOTotalDoFiltro`.
+
+- **`MongoRepository.Get(object key)` / `GetAsync` / `Load` só aceitam chaves ObjectId.**
+  Qualquer chave que não parseie como `ObjectId` (int, Guid, string arbitrária
+  — formatos legítimos de `_id` no MongoDB) retorna `null` **silenciosamente,
+  sem consultar o servidor** e sem lançar erro. Entidades com Id não-ObjectId
+  ficam inacessíveis por chave. `// BUG?:` caracterizado em
+  `MongoRepositoryUnitTests.Get_ComChaveNaoObjectId_RetornaNullSemConsultarOServidor`.
+
+- **`MongoRepository` não participa da transação do `MongoUnitOfWork`.**
+  O repositório nunca usa `MongoUnitOfWork.CurrentSession` (`IClientSessionHandle`);
+  todas as operações executam fora da sessão transacional. Consequência:
+  `uow.BeginTransaction(); repo.Save(x); uow.Rollback();` **não desfaz** o
+  `Save` — o documento permanece no banco. O UnitOfWork só tem efeito sobre
+  operações feitas manualmente com a sessão. `// BUG?:` caracterizado em
+  `MongoUnitOfWorkTests.Rollback_Caracterizacao_NaoDesfazOperacoesDoRepositorio`.
+
+- **`Get(predicate)` sync e async divergem.** A versão síncrona usa
+  `SingleOrDefault` (lança `InvalidOperationException` com múltiplos
+  resultados); `GetAsync(predicate)` usa `FirstOrDefault` (retorna o primeiro
+  sem validar unicidade). Mesmo contrato, semânticas diferentes. `// BUG?:`
+  caracterizado em
+  `MongoRepositoryAsyncTests.GetAsync_PorPredicadoComMultiplosResultados_NaoLanca_DiferenteDoSync`.
+
+- Observação (comportamento documentado, não necessariamente bug):
+  `Refresh`/`RefreshAsync` devolvem uma **nova** instância lida do banco e não
+  atualizam a instância passada (diferente do NH, que recarrega in-place) —
+  coberto em `MongoRepositoryCrudTests.Refresh_DeveRecarregarDoBanco`.
+
+## Codout.Framework.NH
+
+- **`Codout.Framework.NH/NHRepository.cs` — `AllReadOnly`/`WhereReadOnly` têm efeito colateral permanente na sessão.**
+  Ambos setam `Session.DefaultReadOnly = true` e **nunca restauram** o valor:
+  a sessão inteira vira read-only dali em diante. Qualquer entidade carregada
+  depois (mesmo via `All()`/`Get()`) sai do dirty-check e alterações são
+  silenciosamente ignoradas no `Flush`. `// BUG?:` caracterizado em
+  `NHRepositoryQueryTests.AllReadOnly_EfeitoColateral_EntidadesCarregadasDepoisNaoSaoPersistidas`.
+
+- **`NHRepository.WherePaged` não exige ordenação** — `Skip/Take` sem
+  `ORDER BY` produz paginação não determinística em SQL (o mesmo vale para a
+  versão Mongo). Comentário `// BUG?:` em
+  `NHRepositoryQueryTests.WherePaged_SemOrdenacaoExplicita_NaoFalha`.
+
+- `tests/Codout.Framework.NH.Tests/TestInfrastructure.cs` cobre o mapeamento
+  FluentNHibernate básico (`ClassMap` de `Widget`, PK identity, SchemaExport)
+  — o build da factory + CRUD completo passa sobre SQLite.

+# FINDINGS — suítes de teste DynamicLinq / Api.Dto / Application / Api.Client / Api / Multitenancy (sessão E)
+
+Achados registrados durante a criação das suítes `Codout.DynamicLinq.Tests`,
+`Codout.Framework.Api.Dto.Tests`, `Codout.Framework.Application.Tests`,
+`Codout.Framework.Api.Client.Tests`, `Codout.Framework.Api.Tests` e
+`Codout.Multitenancy.Tests`. Nenhum código de produção foi alterado; os
+comportamentos abaixo estão cobertos por testes de caracterização (marcados
+com `// BUG?:` quando aplicável).
+
+## Codout.DynamicLinq
+
+- **`Codout.DynamicLinq/QueryableExtensions.cs`**
+  - O overload "simples" `ToDataSourceResult(take, skip, sort, filter)` repassa
+    `aggregates`/`group` nulos para o overload completo, e tanto `Aggregates()`
+    quanto o corpo principal fazem `xs as T[] ?? xs.ToArray()` — com argumento
+    nulo, `ToArray()` lança `ArgumentNullException`. O mesmo vale para `sort`
+    nulo (em `Sort()`) quando não há grupos. Consequência: o overload de 4
+    parâmetros e o overload `ToDataSourceResult(DataSourceRequest)` com um
+    request recém-criado (propriedades nulas) **sempre lançam exceção**. Para
+    funcionar, o chamador precisa passar coleções vazias.
+    Coberto em `ToDataSourceResultSortPageTests.OverloadSemAggregatesEGroups_LancaArgumentNullException`,
+    `OverloadComDataSourceRequestPadrao_LancaArgumentNullException` e
+    `SortNulo_SemGrupos_LancaArgumentNullException`.
+  - Um `Filter` simples (sem `Logic`) é **ignorado silenciosamente**: `Filters()`
+    só aplica o filtro quando `filter.Logic != null`, então todo filtro de uma
+    condição precisa ser embrulhado em um composto (`Logic = "and"`). Coberto em
+    `ToDataSourceResultFilterTests.Filtro_SemLogic_EhIgnoradoSilenciosamente`.
+
+- **`Codout.DynamicLinq/EnumerableExtensions.cs`**
+  - `GroupByMany` repassa `Group.Aggregates` (nulo por padrão) para
+    `QueryableExtensions.Aggregates`, que lança `ArgumentNullException` na
+    enumeração dos grupos (a avaliação é deferida — a exceção só aparece quando
+    `result.Groups` é enumerado). Todo `Group` precisa de `Aggregates = []`.
+    Coberto em `AggregatesAndGroupTests.Group_SemAggregates_LancaAoEnumerarOsGrupos`.
+
+## Codout.Framework.Api.Dto
+
+- Os tipos do pacote (via shared project `Codout.Framework.Dto.Shared`) são
+  declarados no namespace **`Codout.Framework.Api.Client`**, e não em
+  `Codout.Framework.Api.Dto` — observação de contrato, documentada em
+  `DtoContractTests.TiposDoPacote_EstaoNoNamespaceCodoutFrameworkApiClient`.
+
+## Codout.Framework.Application
+
+- **`Codout.Framework.Application/CrudAppServiceBase.cs`**
+  - `SaveAsync(null)` lança `NullReferenceException` (em vez de
+    `ArgumentNullException`) e a mensagem usa `nameof(TDto)`, que vira o texto
+    literal `"TDto"` em vez do nome real do DTO. Coberto em
+    `CrudAppServiceBaseTests.SaveAsync_ComEntradaNula_LancaNullReferenceException`.
+  - `GetAllAsync(new DataSourceRequest())` lança `ArgumentNullException` (mesma
+    causa raiz do bug de DynamicLinq acima): um consumidor que poste um request
+    "vazio" na API recebe erro. Coberto em
+    `CrudAppServiceBaseTests.GetAllAsync_ComRequestPadrao_LancaArgumentNullException`.
+  - `UpdateAsync` nunca chama `Repository.Update/SaveOrUpdate` — depende de a
+    entidade estar rastreada pelo ORM e do `UnitOfWork.Commit()`. Funciona com
+    EF/NH, mas não com repositórios sem change tracking (observação,
+    caracterizada em `UpdateAsync_NaoChamaUpdateDoRepositorio`).
+
+- **`Codout.Framework.Application/MapperProfile.cs`**
+  - O `ReverseMap()` de `CreateMap(typeof(Entity<>), typeof(EntityDto<>))` não
+    consegue materializar entidades concretas: ao mapear `EntityDto<Guid>` →
+    `Customer`, o AutoMapper tenta instanciar a classe **abstrata**
+    `Entity<Guid>` e lança `ArgumentException`. Na prática,
+    `Mapper.Map<TEntity>(input)` — usado por `CrudAppServiceBase.SaveAsync` —
+    falha se o consumidor não registrar um mapa próprio DTO→Entidade. Coberto em
+    `MappingProfileTests.MappingProfile_MapaReverso_NaoConsegueCriarEntityConcreta`.
+
+## Codout.Framework.Api.Client
+
+- **`Codout.Framework.Api.Client/Extensions/HttpClientExtensions.cs`**
+  - `GetExceptionAsync` lança `new ApiClientException(...)` **dentro do próprio
+    bloco try**; o `catch` genérico logo abaixo a engole e relança
+    `new Exception(corpo)`. Resultado: o `ApiClientException` tipado (com o
+    `ApiException` estruturado) **nunca chega ao chamador** — toda resposta de
+    erro vira `Exception` com o corpo bruto como mensagem. Coberto em
+    `HttpClientExtensionsTests.RespostaDeErro_ComCorpoDeApiException_LancaExceptionGenericaComOCorpo`.
+
+- **`Codout.Framework.Api.Client/RestApiClient.cs`**
+  - Em `DeleteAsync`, a chamada `Client.DeleteAsync(...)` resolve para o método
+    de **instância** `HttpClient.DeleteAsync` (métodos de instância têm
+    precedência sobre extensões), e não para a extensão
+    `HttpClientExtensions.DeleteAsync` que valida o status. Consequência:
+    **erros HTTP no DELETE são silenciosamente ignorados** (nenhuma exceção é
+    lançada para 4xx/5xx). Coberto em
+    `RestApiClientTests.DeleteAsync_ComRespostaDeErro_NaoLancaExcecao`.
+
+- **`Codout.Framework.Api.Shared/ApiException.cs`** — `ApiException` é um POCO
+  (não herda de `System.Exception`), portanto não pode ser lançada diretamente;
+  apenas serializada/embrulhada (observação, caracterizada em
+  `ApiExceptionTests.ApiException_NaoEhUmaException`).
+
+- **`Codout.Framework.Api.Client/ApiClientBase.cs`** — o `HttpClient` é criado
+  internamente, sem ponto de injeção de `HttpMessageHandler`; os testes de
+  `RestApiClient` substituem o handler via reflection (campo privado
+  `HttpMessageInvoker._handler`) para evitar rede (observação de testabilidade).
+
+## Codout.Framework.Api
+
+- **`Codout.Framework.Api/Middleware/ApiExceptionMiddleware.cs`**
+  - Ao capturar uma exceção, o middleware **não altera `Response.StatusCode`**:
+    serializa o status vigente (200) no corpo e responde `200 OK` para qualquer
+    exceção não tratada, em vez de 500. Coberto em
+    `ApiExceptionMiddlewareTests.QuandoHaExcecao_StatusCodePermanece200`.
+
+- **`Codout.Framework.Api/RestApiEntityBase.cs`**
+  - `Get` retorna `200 OK` com corpo nulo quando a entidade não existe, embora o
+    contrato anunciado via `ProducesResponseType` inclua `404 NotFound`. Coberto
+    em `RestApiEntityBaseTests.Get_QuandoNaoEncontrado_RetornaOkComCorpoNulo`.
+
+## Codout.Multitenancy
+
+- **`Codout.Multitenancy/MemoryCacheTenantResolver.cs`**
+  - O cache é **consultado** com a chave de `GetContextIdentifier(httpContext)`,
+    mas **gravado** com a chave de `GetTenantIdentifier(tenantContext)`. Se as
+    duas convenções diferirem (ex.: busca por host, gravação por chave do
+    tenant), a consulta nunca encontra a entrada gravada e o tenant é
+    re-resolvido a cada request (cache inócuo + entradas órfãs). Só funciona
+    quando as implementações retornam o mesmo valor. Coberto em
+    `MemoryCacheTenantResolverTests.ResolveAsync_QuandoChaveDeBuscaDifereDaChaveDeGravacao_NuncaUsaOCache`.
+
+- **`Codout.Multitenancy/Internal/TenantPipelineMiddleware.cs`**
+  - Quando não há `TenantContext` no request, o middleware **não chama `_next`**:
+    o restante do pipeline é curto-circuitado silenciosamente (resposta vazia
+    200). Coberto em
+    `TenantPipelineMiddlewareTests.UsePerTenant_SemTenant_CurtoCircuitaSemExecutarORoot`.
+
+- Observação: a pasta `Codout.Multitenancy` contém dois csproj que compilam os
+  mesmos fontes (`Codout.Multitenancy.csproj` net10.0 e
+  `Softprime.Multitenancy.csproj` netstandard2.0); a suíte referencia o
+  `Codout.Multitenancy.csproj`. A chave usada em `HttpContext.Items` ainda é
+  `"softprime.TenantContext"` (resquício do nome antigo).

Subject: [PATCH 13/24] chore: liga nullable, analyzers, TreatWarningsAsErrors
 e SourceLink globais (Fases 5-6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Directory.Build.props: Nullable enable, TreatWarningsAsErrors,
  EnableNETAnalyzers latest-recommended, GenerateDocumentationFile
  (CS1591 suprimido até completar XML docs), SourceLink GitHub,
  snupkg, PackageLicenseExpression MIT
- Directory.Build.targets: embarca README.md por pacote como
  PackageReadmeFile automaticamente
- .editorconfig: regras CA de estilo/perf/naming rebaixadas para
  suggestion (corrigir exige mudança de código — fica para PRs
  dedicados); categorias relaxadas em tests/
- fix(mongo): MongoDB.Driver 3.7.0 -> 3.9.0 (corrige vulnerabilidades
  conhecidas nos transitivos SharpCompress 0.30.1 e Snappier 1.0.0)
- Remove PackageReference desnecessárias (NU1510): Microsoft.CSharp,
  Caching.Memory e System.ComponentModel.Annotations (inbox no net10)

Codout.Framework.Common compila limpo sob Nullable enable +
TreatWarningsAsErrors + latest-recommended: anotações '?' refletindo
a API real, null-forgiving só onde comprovadamente seguro, rename do
type parameter da LimitedList.Enumerator (CS0693), correções CA
mecânicas 100% equivalentes (ThrowIfNull, Enum.GetValues<T>, sealed)
e supressões justificadas via #pragma onde corrigir mudaria API.
BOM removido de 18 arquivos legados. 237 testes seguem verdes sem
alteração de asserções.

From ba87eec5df4b90ec6b04b231597202054f0241f6 Mon Sep 17 00:00:00 2001
From: Claude <noreply@anthropic.com>
Date: Fri, 12 Jun 2026 04:36:21 +0000
Subject: [PATCH 19/24] feat: package validation com baseline do NuGet.org em
 todos os pacotes (Fase 6)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- EnablePackageValidation + PackageValidationBaselineVersion (6.3.0/
  6.4.0) nos 24 csproj publicáveis: o pack falha se a API quebrar vs.
  a versão publicada
- A validação já pegou e reverteu duas quebras acidentais da anotação
  nullable: rename do type parameter LimitedList.Enumerator (CP0001)
  e metadados notnull em JsonExtensions (CP0021) — bloco extension
  mantido oblivious até o próximo major
- Pack dos 24 pacotes validado localmente (nupkg + snupkg); 921
  testes verdes

 ## 2026-06-12
 
+> Mudanças abaixo ainda **não publicadas** no NuGet.org — os bumps de versão
+> acontecerão na próxima release de cada pacote.
+
+### Tests
+
+- Fase 4 do ROADMAP concluída: **921 testes** em 18 projetos sob `tests/`, cobrindo os 24 pacotes publicáveis (Common, Security, Image, Data, Domain, EF com SQLite, Mongo com mongod efêmero + replica set, NH com SQLite, Mailer + AWS/SendGrid/Razor com mocks e Razor real, Storage, Storage.Azure, DynamicLinq, Api.Dto, Application, Api.Client, Api, Multitenancy). Bugs pré-existentes encontrados foram **caracterizados** (testes documentam o comportamento atual, sem alterá-lo) e catalogados em `tests/FINDINGS-{A..E}.md` para triagem.
+
+### Build
+
+- `Directory.Build.props`: ligados globalmente `Nullable`, `TreatWarningsAsErrors`, analyzers .NET (`latest-recommended`), `GenerateDocumentationFile` (CS1591 suprimido até completar as docs por pacote), SourceLink (GitHub), símbolos `snupkg`, `PackageLicenseExpression MIT` e build determinístico em CI. `.editorconfig` calibra regras CA de estilo/perf como suggestion (subir severidade é trabalho incremental).
+- **Package validation**: todos os 24 csproj publicáveis têm `EnablePackageValidation` + `PackageValidationBaselineVersion` apontando para a última versão no NuGet.org — o `pack` falha se a API pública quebrar vs. a baseline. A validação já reverteu duas quebras acidentais durante a anotação nullable (CP0001 em `LimitedList.Enumerator`, CP0021 em `JsonExtensions`).
+- `Directory.Build.targets`: `README.md` de cada pasta de pacote é embarcado automaticamente como `PackageReadmeFile` no nupkg.
+- Anotações **nullable** em todos os pacotes refletindo o contrato real (ex.: `IRepository<T>.GetAsync`/`LoadAsync` agora declaram `Task<T?>`). Sem mudança de comportamento — apenas metadados; consumidores com nullable habilitado podem ver warnings novos (e verdadeiros).
+
+### Codout.Framework.Mongo (não publicado)
+
+#### Fixed
+- `MongoDB.Driver` 3.7.0 → 3.9.0, eliminando vulnerabilidades conhecidas nos transitivos `SharpCompress` 0.30.1 (moderada) e `Snappier` 1.0.0 (alta).
+
 ### Repository
 
 - Removidas as árvores legadas `NetFull/`, `NetCore/`, `src/NetCore/` (Cosmos/DocumentDB em `netcoreapp2.0`, EOL), `Codout.Framework.DP` (quebrado, referenciava `Codout.Framework.DAL` inexistente), `Shared/Codout.Framework.Shared.Commom` e `Shared.msbuild`. Nenhum desses projetos era publicado no NuGet (`IsPackable=false` ou fora de `.github/release-packages.json`); o histórico permanece no git. O typo "Commom" deixa de existir no repositório.

+# FINDINGS — Bugs pré-existentes encontrados pela Fase 4 (triagem)
+
+Durante a escrita das suítes de teste (2026-06-12), os bugs abaixo foram
+encontrados no código de produção. **Nenhum foi corrigido**: a política da
+fase foi caracterizar o comportamento atual (testes marcados com `// BUG?:`)
+para não alterar contrato sem decisão explícita. Detalhes completos nos
+arquivos `FINDINGS-A.md` a `FINDINGS-E.md` nesta pasta.
+
+## Alta severidade (corrigir primeiro; provável bump patch/minor)
+
+| # | Pacote | Bug | Detalhe |
+|---|--------|-----|---------|
+| 1 | Security.Argon2 | `NeedsRehash` compara com parâmetros errados — todo hash criado via `Strength` se reporta `SuccessRehashNeeded` para sempre (rehash a cada login) | FINDINGS-A |
+| 2 | Mongo | `WherePaged` calcula `total` depois de Skip/Take — retorna o tamanho da página, não o total do filtro | FINDINGS-D |
+| 3 | Mongo | `MongoRepository` não participa da transação do `MongoUnitOfWork` — `Rollback` não desfaz escritas | FINDINGS-D |
+| 4 | EF | Interceptor de auditoria declara cópias locais de `IAuditable`/`ICurrentUserProvider` que sombreiam as de `Data.Auditing` — entidades auditáveis são ignoradas silenciosamente | FINDINGS-B |
+| 5 | Api | `ApiExceptionMiddleware` nunca seta `Response.StatusCode` — exceções respondem `200 OK` | FINDINGS-E |
+| 6 | NH | `AllReadOnly`/`WhereReadOnly` setam `Session.DefaultReadOnly=true` permanentemente — escritas posteriores na mesma sessão são ignoradas no Flush | FINDINGS-D |
+| 7 | Multitenancy | `MemoryCacheTenantResolver` lê o cache pela chave de contexto e grava pela de tenant — se diferirem, o cache nunca acerta | FINDINGS-E |
+
+## Média severidade
+
+| # | Pacote | Bug | Detalhe |
+|---|--------|-----|---------|
+| 8 | Mailer | `MailerServiceBase` loga `model.To.Address` antes do try — NRE escapa em vez de `MailerResponse{Sent=false}` | FINDINGS-C |
+| 9 | DynamicLinq | Overloads de `ToDataSourceResult` sem `aggregates`/`group` lançam `ArgumentNullException`; filtro sem `Logic` é ignorado | FINDINGS-E |
+| 10 | Application | `UpdateAsync` nunca chama `Repository.Update`; `SaveAsync(null)` lança NRE com mensagem `"TDto"` | FINDINGS-E |
+| 11 | Api.Client | Erros HTTP de DELETE silenciosamente ignorados (binding ao método de instância do HttpClient); `ApiClientException` engolida pelo próprio catch | FINDINGS-E |
+| 12 | Mongo | `Get`/`GetAsync`/`Load` com chave não-ObjectId retornam null sem consultar; sync usa `SingleOrDefault`, async usa `FirstOrDefault` | FINDINGS-D |
+| 13 | Storage.Azure | URI de CDN não faz URL-encoding do fileName; `AddAzureStorage` instancia eagerly | FINDINGS-C |
+| 14 | EF | `RefreshAsync(entity, ct)` executa `Reload()` síncrono e ignora o token; `Commit()` × `CommitAsync()` assimétricos sem transação | FINDINGS-B |
+| 15 | Common | `RemoveAccents` quebrado no .NET moderno (codepage não registrada); `GetAge` erra no dia do aniversário; `IsEmail("")` retorna true | FINDINGS-A |
+
+## Baixa severidade / observações de design
+
+- `MailerHealthCheck` sempre Healthy, campo `_dispatcher` morto (FINDINGS-C).
+- `SendGridSettings.StandBox` (typo) sem uso; `EnableCache` do Razor sem efeito (FINDINGS-C).
+- `Api.Dto` vive no namespace `Codout.Framework.Api.Client` (FINDINGS-E).
+- `TenantPipelineMiddleware` sem tenant não chama `_next` (FINDINGS-E).
+- `FileSystemStorageOptions`/`AwsStorageOptions` existem sem implementação (FINDINGS-C).
+- `Get(predicate)` do Mongo: divergência sync/async de semântica (FINDINGS-D).
+- `Chop`, `HtmlEncode` (duplo escape), `EnumHelper.GetLocalizedName` lendo `Description` (FINDINGS-A).
+
+## Como corrigir com segurança
+
+Cada correção deve: (1) ajustar o characterization test correspondente para o
+comportamento correto, (2) passar no package validation (baseline NuGet), e
+(3) entrar no CHANGELOG do pacote com bump apropriado (a maioria é patch;
+itens que mudam contrato observável, como #2 e #5, merecem minor + nota).

Subject: [PATCH 22/24] docs(domain,data): XML docs completas com CS1591 como
 erro + gate de cobertura no CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Domain: 18 tipos/membros documentados em português; Data: docs
  erradas corrigidas (IEntity truncada, cref enganoso)
- CS1591 reativado como erro nos dois pacotes-núcleo (teste negativo
  validado)
- dotnet.yml: gate de cobertura ratchet em 45% (atual 47,4%) sobre os
  assemblies Codout.*
- ROADMAP: status final das fases

Subject: [PATCH 23/24] chore(release): bump minor de todos os pacotes (6.4.0 /
 core 6.5.0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prepara o release das melhorias das Fases 1-8 sem publicar: bump
minor coordenado nos 24 pacotes publicáveis (Data/Domain/EF para
6.5.0, demais para 6.4.0). Baseline do package validation mantida na
versão publicada. Sem criar tag — publicação aguarda merge na master
e revisão.

Subject: [PATCH 24/24] ci: neutraliza AppVeyor com no-op (build/test off)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A integração do AppVeyor seguiu ativa no nível do serviço após a
remoção do yml legado e passou a falhar no auto-build (raiz com
múltiplas solutions). Como o CI real é o GitHub Actions, este yml
desliga build/test para o check reportar verde. Para remover o check
de vez, desconectar o AppVeyor nas settings do GitHub.
