Summary

Separates immutable release publication from asynchronous NuGet.org indexing and restructures the Repo2C4 release workflow into governed stages similar to Dapper-FluentMap.

Problem

The previous release workflow combined tag creation, GitHub Release creation and NuGet publication in one job, then used public NuGet consumer installation as a post-publication gate. A transient NuGet indexing delay could therefore mark an already-published immutable version as failed.

Changes

  • restructure the release graph into:
    • Validate, build, test and pack;
    • Create release tag;
    • parallel Publish to NuGet.org and Publish to GitHub Packages;
    • Create GitHub Release only after both package registries succeed;
    • Roll back failed release as a compensating job;
  • build and validate the package payload once, then reuse the exact artifact in every publication job;
  • retain the release tag on downstream failure so retries remain bound to the validated commit;
  • never delete immutable NuGet.org or GitHub Packages versions during rollback;
  • keep NuGet public indexing out of the immutable release gate;
  • move Official MCP Registry publication into a standalone manual workflow;
  • make the Registry workflow resolve the released version while allowing registry-only metadata corrections;
  • shorten server.json description to satisfy the Official MCP Registry 100-character limit;
  • update English and Portuguese distribution documentation.

Expected release graph

Validate/build/test/pack → Create release tag → [NuGet.org || GitHub Packages] → Create GitHub Release → Rollback (only on failure)

Expected behavior

A release is considered successful when the validated package payload is accepted by both package registries and the GitHub Release is created. NuGet indexing and MCP Registry publication happen outside that immutable release boundary and can be retried independently without burning another package version.

Summary by CodeRabbit

  • Publicação

    • Releases publicam os pacotes no NuGet.org e no GitHub Packages em paralelo. A GitHub Release é criada somente após o sucesso das duas publicações.
    • A publicação de metadados no Official MCP Registry ocorre em um fluxo manual separado, após a versão correspondente estar disponível publicamente no NuGet.org. Se a indexação ainda estiver pendente, o fluxo pode ser repetido para a mesma versão.
  • Documentação

    • Atualizadas as instruções de distribuição para explicar o processo de publicação e a indexação assíncrona do NuGet.
    • Ajustada a descrição do servidor MCP para destacar documentação de arquitetura C4 revisável e baseada em evidências.

📝 Walkthrough

Walkthrough

O PR reorganiza a publicação: o workflow de release valida e publica pacotes no NuGet.org e no GitHub Packages antes de criar o GitHub Release. Um workflow manual separado valida o pacote MCP e publica seus metadados no Official MCP Registry.

Changes

Release e publicação MCP

Layer / File(s) Summary
Validação e empacotamento da release
.github/workflows/release.yml
O workflow valida a versão, o commit, os PackageIds e os metadados de server.json. Empacota os produtos, verifica os checksums e disponibiliza o payload validado como artefato.
Tag, publicação dos pacotes e GitHub Release
.github/workflows/release.yml
O workflow confirma ou cria a tag e publica os pacotes no NuGet.org e no GitHub Packages. Após as duas publicações, cria ou atualiza o GitHub Release. Em caso de falha, remove um release parcial quando aplicável, mas mantém a tag e os pacotes publicados.
Validação do pacote MCP
.github/workflows/publish-mcp-registry.yml, server.json
O workflow manual exige versão e confirmação, resolve a tag e valida os metadados. Tenta instalar e executar a versão correspondente do pacote NuGet. A descrição de server.json passa a caracterizar o servidor como voltado à documentação de arquitetura C4 revisável e baseada em evidências.
Publicação manual dos metadados e documentação
.github/workflows/publish-mcp-registry.yml, README.md, README.pt-BR.md, docs/distribution.md, docs/distribution.pt-BR.md
O workflow consulta a versão no Registry e publica os metadados quando ela não existe. Os documentos descrevem a publicação paralela dos pacotes e a publicação manual dos metadados MCP após a disponibilidade pública do pacote NuGet.

Merge Risk: 🟡 Moderate · up to a2114

Publishing a release would run unintended global tool installs during GitHub Release creation. The published release notes would lose their install instructions. Quote or escape the release-notes heredoc before merging. The distribution docs may also still describe release jobs that this change removed.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a2114

Publication remains manually gated and uses validated files, but duplicate uploads no longer establish that an existing registry package matches those files. The likely exposure is limited by commit checks, serialized releases, and restricted publishing authority.

Retained concerns

  • Medium · security · observed: Duplicate publication now succeeds without comparing the existing immutable package with the validated payload. The earlier NuGet path performed that comparison after a failed push. A conflicting version from another authorized publisher, or one missed during preflight visibility checks, can therefore satisfy the publication gate while differing from the GitHub Release attachments. Ordinary retries using the original artifact are substantially constrained by tag checks and serialization.
Security review details

Security Blast Radius

  • inferred — A publication-integrity failure could affect consumers of the three public tools and their release attachments. Creating conflicting registry state requires separate package-publishing authority or compromise; the evidence does not establish an anonymous path or authority over unrelated tenants or namespaces.

Security Findings and Attack Paths

  • inferred — The remaining integrity path is a conflicting immutable version that escapes initial visibility checks or appears during publication. Duplicate acceptance can then let release creation proceed without proving remote payload equality. Serialized workflow runs, existing-version rejection, and original-artifact recovery constrain this path; no actual conflicting version was demonstrated.

Trust Boundaries and Controls

  • observed — The manual MCP entrypoint requires main, a constrained version, explicit confirmation, and a matching non-draft release. Checkout credentials are not persisted, and namespace and package fields are fixed before publication. Repository evidence does not establish release-environment approvers or the external registry's effective OIDC authorization policy.

Resilience and Maintainability Implications

  • observed — The standalone metadata checks do not repeat distribution validation of the official NuGet base URL and required local repository-root argument. CI does run that validation on pull requests and main pushes, providing counterevidence against uncontrolled metadata drift. The publication workflow does not itself require a successful CI result for its metadata commit, and enforcement through branch protection is unverified.

Hardening Proposals

  • proposed — Keep asynchronous indexing outside the release gate, but treat a duplicate response as a reconciliation state until remote payload identity is established. For independently corrected metadata, reuse the security-relevant distribution assertions without requiring identical descriptive metadata.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Atualize a seção de release nos dois idiomas: ela ainda descreve os jobs pós-publicação, que foram removidos.

Este PR removeu os jobs post-publish e publish-mcp-registry de .github/workflows/release.yml. A seção de release nos dois documentos ainda diz que um job de consumidor público e um job OIDC do Registry rodam após o push NuGet. Esse texto contradiz a linha 50 alterada nos mesmos arquivos.

  • docs/distribution.md#L131-L131: substitua as frases "A final read-only consumer job..." e "After that succeeds, a separate OIDC-scoped job..." por um texto que diga que o release termina após a GitHub Release. O texto deve dizer também que a publicação no Registry ocorre pelo workflow manual Publish Repo2C4 MCP Registry metadata.
  • docs/distribution.pt-BR.md#L126-L126: substitua as frases "Depois, um job somente leitura..." e "Quando esse smoke público passa, um job separado com OIDC..." pela descrição equivalente do workflow manual separado.

As per path instructions: "Verifique se documentação, exemplos e contratos descritos continuam coerentes com a API implementada."
