feat(ci): add a manual finalize lane for signed Draft packages

GPG-signing the RPMs rewrites their bytes after release.yml has already generated SBOMs, the packages checksum manifest, and attestations from the as-built files. The new workflow_dispatch-only finalize-release lane runs between signing and publishing: it refuses non-Draft releases, verifies the signed RPMs against their sha256 sidecars and the committed PGSTY public key, confirms every other package still matches the original manifest, regenerates the RPM SBOMs and the manifest from the published bytes, cosign-signs the manifest under the workflow identity, and attests the finalized set before replacing the assets in place. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
fix(ci): match checksum manifest entries exactly in docker-release

 # AGPLv3 Compliance

-We have designed MinIO as an Open Source software for the Open Source software community. This requires applications to consider whether their usage of MinIO is in compliance with the GNU AGPLv3 [license](https://github.com/minio/minio/blob/master/LICENSE).
+Silo is distributed under the [GNU Affero General Public License v3.0](LICENSE).
+It incorporates source code from the MinIO project and preserves the original
+copyright, license, and attribution notices in [`NOTICE`](NOTICE),
+[`CREDITS`](CREDITS), and source-file headers.

-MinIO cannot make the determination as to whether your application's usage of MinIO is in compliance with the AGPLv3 license requirements. You should instead rely on your own legal counsel or licensing specialists to audit and ensure your application is in compliance with the licenses of MinIO and all other open-source projects with which your application integrates or interacts. We understand that AGPLv3 licensing is complex and nuanced. It is for that reason we strongly encourage using experts in licensing to make any such determinations around compliance instead of relying on apocryphal or anecdotal advice.
+You are responsible for determining how the AGPLv3 applies to your use,
+modification, deployment, and distribution of Silo and its dependencies. The
+Silo maintainers cannot provide legal advice or determine whether a particular
+application or service satisfies the license. Consult qualified counsel when
+the obligations are material to your deployment.

-[MinIO Commercial Licensing](https://min.io/pricing) is the best option for applications that trigger AGPLv3 obligations (e.g. open sourcing your application). Applications using MinIO - or any other OSS-licensed code - without validating their usage do so at their own risk.
+If you convey modified binaries or provide network access to a modified
+version, review the complete AGPLv3 text and ensure that the corresponding
+source and notices are made available as required. Dependency licenses and
+separate notices continue to apply independently.

+# Contributing to Silo

-``MinIO`` community welcomes your contribution. To make the process as seamless as possible, we recommend you read this contribution guide.
+Silo welcomes focused contributions that improve security, reliability,
+compatibility, packaging, tests, or maintainability. This repository preserves
+MinIO-compatible interfaces and storage formats, so changes must identify and
+test any compatibility impact.

 ## Development Workflow

-Start by forking the MinIO GitHub repository, make changes in a branch and then send a pull request. We encourage pull requests to discuss code changes. Here are the steps in details:
+Fork the current Silo source repository, create a topic branch, and submit a
+pull request. Discuss broad or compatibility-sensitive changes in an issue
+before implementation.

-### Setup your MinIO GitHub Repository
-
-Fork [MinIO upstream](https://github.com/minio/minio/fork) source repository to your own personal repository. Copy the URL of your MinIO fork (you will need it for the `git clone` command below).
+### Set up a checkout

 ```sh
-git clone https://github.com/minio/minio
-cd minio
-go install -v
-ls $(go env GOPATH)/bin/minio
+git clone https://github.com/pgsty/silo
+cd silo
+go build -o silo .
+./silo --version
 ```

-### Set up git remote as ``upstream``
+### Keep the lineage remote separate

 ```sh
-$ cd minio
-$ git remote add upstream https://github.com/minio/minio
-$ git fetch upstream
-$ git merge upstream/master
-...
+git remote add lineage https://github.com/minio/minio
+git fetch lineage
 ```

+Do not merge an upstream branch into a pull request unless the maintainers have
+agreed on the scope. Silo intentionally carries a small downstream delta.
+
 ### Create your feature branch

-Before making code changes, make sure you create a separate branch for these changes
+Create a separate branch before making code changes:

 ```
 git checkout -b my-new-feature
 ```

-### Test MinIO server changes
+### Test Silo server changes

-After your code changes, make sure
+Before opening a pull request:

- To add test cases for the new code. If you have questions about how to do it, please ask on our [Slack](https://slack.min.io) channel.
- To run `make verifiers`
- To squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
- To run `make test` and `make build` completes.
+- Add or update tests for changed behavior.
+- Run `make verifiers`.
+- Run the smallest relevant package tests, then `make test` when practical.
+- Run `make build` and confirm the generated executable is `silo`.
+- Explain any preserved `MINIO_*`, `minio_*`, `x-minio-*`, `/minio/*`,
+  `.minio.sys`, ARN, module/import-path, or serialized compatibility name.

 ### Commit changes

-After verification, commit your changes. This is a [great post](https://chris.beams.io/posts/git-commit/) on how to write useful commit messages
+After verification, commit your changes with a concise message and a DCO
+sign-off (see [Licensing of Contributions](#licensing-of-contributions)):

 ```
-git commit -am 'Add some feature'
+git commit -s -am 'Fix object replication retry handling'
 ```

 ### Create a Pull Request

-Pull requests can be created via GitHub. Refer to [this document](https://help.github.com/articles/creating-a-pull-request/) for detailed steps on how to create a pull request. After a Pull Request gets peer reviewed and approved, it will be merged.
+Pull requests should include motivation, reproduction steps where applicable,
+test evidence, compatibility notes, and documentation impact. Public product
+documentation is owned by the separate
+[`pgsty/silo.pgsty.com`](https://github.com/pgsty/silo.pgsty.com) repository.
+
+## Licensing of Contributions
+
+Silo is licensed under the [GNU AGPL v3.0 or later](LICENSE). Its core is
+Copyright (c) MinIO, Inc.; the combined work can never be relicensed, and this
+fork does not try to.
+
+* **No CLA.** We do not ask you to sign a Contributor License Agreement and we
+  do not take your copyright. Contributions are accepted inbound=outbound: you
+  keep the copyright to your changes and license them under the same
+  AGPL-3.0-or-later as the project itself. The maintainers receive no rights
+  beyond the project license.
+
+* **DCO sign-off required.** Every commit must carry a
+  `Signed-off-by: Your Name <you@example.com>` trailer certifying the
+  [Developer Certificate of Origin 1.1](https://developercertificate.org/) —
+  your statement that you have the right to submit the code under the project
+  license. Sign each commit with:
+
+  ```
+  git commit -s
+  ```
+
+  Forgot some? Repair your branch with `git rebase --signoff` and force-push.
+  CI rejects pull requests containing unsigned commits; the sign-off email
+  must match the commit author email. (Lowercase `-s` is the plain-text DCO
+  sign-off; cryptographic `-S`/GPG signing is welcome but independent.)
+
+* **Provenance.** Only submit code you are entitled to submit. This matters
+  more here than in most projects: Silo carries a downstream delta over an
+  upstream code base, and cherry-picks from the lineage remote or other forks
+  are routine. When relaying a patch written by someone else, preserve original
+  authorship (`git cherry-pick -x`, keep the author field and any existing
+  `Signed-off-by` trailers) and add your own sign-off as the person passing it
+  along. Never import code from a proprietary distribution.
+
+* **File headers.** Files derived from upstream keep the original MinIO
+  copyright header unchanged. New files added by this fork use the dual
+  header, followed by the standard AGPL boilerplate:
+
+  ```
+  // Copyright (c) 2015-2025 MinIO, Inc.
+  // Copyright (c) 2025-2026 PGSTY
+  ```
+
+* **Squash merges** must keep the `Signed-off-by:` trailers in the resulting
+  commit message.
+
+* **Authorship and tooling.** The human contributor is the author of the commit
+  and the sole signatory of its DCO sign-off. Attribution trailers for
+  assistive tooling (for example `Co-Authored-By:` naming an AI assistant) are
+  informational only: they record which tools were used, and do not create
+  authorship, co-authorship, or any copyright claim. Whoever signs off remains
+  responsible for the content of the commit, whatever produced it.

+
+> [!NOTE]
+> This repository was renamed from `pgsty/minio` to `pgsty/silo`, and its default branch from `master` to `main`, on 2026-08-06. If you need the artifacts maintained under the original MinIO identity, they are on the archived [`minio`](https://github.com/pgsty/silo/tree/minio) branch and in the releases up to [`RELEASE.2026-08-04T00-00-00Z`](https://github.com/pgsty/silo/releases/tag/RELEASE.2026-08-04T00-00-00Z); those assets and the `docker.io/pgsty/minio` image stay published and unmodified. The rename changed product and artifact names only — `MINIO_*` variables, `minio_*` metrics, `x-minio-*` headers, `/minio/*` routes, and the on-disk format are unchanged.

 ## Overview

-Silo maintains one downstream release line based on MinIO [`RELEASE.2025-12-03T12-00-00Z`](https://github.com/minio/minio/releases/tag/RELEASE.2025-12-03T12-00-00Z). It provides maintained builds and release artifacts for existing MinIO-compatible deployments after upstream community distribution ended. Pigsty uses this fork for object storage as an optional PG backup repo.
+Silo maintains one downstream release line derived from the open-source MinIO server.

-The official project portal is [silo.pgsty.com](https://silo.pgsty.com/). It brings documentation, downloads, release and security notes, and project background together. English is served at the site root; Chinese is available under [/zh/](https://silo.pgsty.com/zh/).
+The fork follows one rule: **the product and its delivery surfaces are renamed; the protocol and your data are not.** The `silo` executable, packages, service, and container image carry the new name, while the S3 API, `MINIO_*` variables, `minio_*` metrics, `x-minio-*` headers, reserved routes, and the on-disk format stay unchanged. The differences are recorded in the [compatibility notes](https://silo.pgsty.com/compatibility/server/).

 ## Maintenance Policy

@@ -66,14 +86,21 @@ Changes are kept narrow and tested where practical. Maintenance is best effort;
 - commercial support, SLAs, 24×7 coverage, or SUBNET access;
 - deployment design, access control, monitoring, backup, or recovery.

+## Governance
+
+The server, client, console, and shared packages are maintained under one release process: DCO-signed commits, reviewed pull requests, and versioned `RELEASE.YYYY-MM-DDTHH-MM-SSZ` tags whose artifacts ship with checksums, SPDX SBOMs, Sigstore-signed manifests, and GitHub build attestations. Each release is announced with a [release note](https://silo.pgsty.com/tags/silo/) on the portal; security handling follows [`SECURITY.md`](SECURITY.md) and the [advisory log](docs/security/advisories.md). Upstream copyright, license, and third-party notices are preserved in [`LICENSE`](LICENSE), [`NOTICE`](NOTICE), and [`CREDITS`](CREDITS).
+
 ## Compatibility

 Silo aims to preserve:

- MinIO-compatible S3 APIs, configuration, environment variables, and CLI conventions;
- `RELEASE.YYYY-MM-DDTHH-MM-SSZ` tags, container entrypoints, and common deployment workflows.
+- the `github.com/minio/minio` module path and `github.com/minio/*` import paths;
+- MinIO-compatible S3 APIs, wire behavior, `MINIO_*` environment variables, metrics, protocol headers, reserved routes, and storage metadata;
+- `RELEASE.YYYY-MM-DDTHH-MM-SSZ` tags and legacy `minio …` container argv translation.

-Compatibility is the default constraint. Silo preserves existing wire, client, configuration, and operational behavior whenever doing so remains safe. Compatibility is broken only when necessary to close a major security issue, and the release notes must identify the affected behavior and migration path. Treat each release as a downstream upgrade: pin versions, review [release notes](https://silo.pgsty.com/blog/release/) and [security advisories](docs/security/advisories.md), keep a rollback path, and test before production use.
+Silo-owned delivery surfaces use the `silo` executable, package, service, Helm chart, and `pgsty/silo` container image. Native artifacts intentionally do not install a `minio` binary alias.

+
+Each new release publishes per-archive and per-package SPDX JSON SBOMs. The archive and package checksum manifests have detached keyless Sigstore bundles, while GitHub artifact attestations record signed provenance for every downloadable artifact and the multi-architecture container image.
+
+After downloading an archive and its release files, verify integrity, the
+published SBOM, the signed manifest, and build provenance independently:
+
+```bash
+# Integrity: choose the line for the artifact you downloaded.
+grep -F '  silo_<version>_linux_amd64.tar.gz' \
+  silo_<version>_checksums.txt | sha256sum --check
+
+# The archive SBOM is a separate checksummed release artifact.
+grep -F '  silo_<version>_linux_amd64.tar.gz.sbom.json' \
+  silo_<version>_checksums.txt | sha256sum --check
+
+# Signature over the archive/SBOM checksum manifest.
+cosign verify-blob \
+  --bundle silo_<version>_checksums.txt.sigstore.json \
+  --certificate-identity-regexp \
+    '^https://github.com/pgsty/(minio|silo)/\.github/workflows/release\.yml@refs/(tags/RELEASE\..+|heads/(master|main))$' \
+  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
+  silo_<version>_checksums.txt
+
+# Signed build provenance (online verification against this repository).
+gh attestation verify silo_<version>_linux_amd64.tar.gz \
+  --repo pgsty/silo
+```
+
+For packages, use `silo_<version>_packages_checksums.txt` and its adjacent
+Sigstore bundle with the same identity and issuer constraints. Inspect the
+verified SPDX JSON SBOM with your preferred SPDX tooling. Verify the
+multi-architecture container provenance by digest:
+
+```bash
+gh attestation verify \
+  oci://index.docker.io/pgsty/silo@sha256:<manifest-digest> \
+  --repo pgsty/silo
+```
+
+The platform SBOM attestations are attached to the `amd64` and `arm64` image
+digests rather than the multi-architecture manifest. Verify each one explicitly:
+
+```bash
+gh attestation verify \
+  oci://index.docker.io/pgsty/silo@sha256:<platform-digest> \
+  --repo pgsty/silo \
+  --predicate-type https://spdx.dev/Document/v2.3
+```
+
+Verification by digest avoids trusting a mutable image tag.
+
+### Native package migration
+
+The `silo` RPM, DEB, and APK do not declare `Provides`, `Obsoletes`,
+`Replaces`, or package-level `Conflicts` against `minio`. They can therefore be
+installed beside an existing MinIO package without silently replacing it. The
+two systemd units conflict at runtime, so switch them explicitly rather than
+starting both.
+
+Before switching, record the old unit's enabled/active state and `User`/`Group`,
+and back up `/etc/default/minio`. Silo reads that legacy defaults file first and
+then `/etc/default/silo`; administrator-set values in the latter take
+precedence. If the existing data must continue to run under its original
+UID/GID, create `/etc/systemd/system/silo.service.d/10-legacy-user.conf`:
+
+```ini
+[Service]
+User=<legacy-user>
+Group=<legacy-group>
+```
+
+Run `systemctl daemon-reload`, then disable and stop `minio.service` before
+enabling and starting `silo.service`. Verify health, S3, Admin API, metrics, and
+logs before masking or uninstalling the old service. Do not recursively change
+data ownership as part of the package migration; keep the old package and unit
+available during the rollback window.

 - 商业支持、SLA、7×24 服务或 SUBNET 服务；

+## 治理
+
+服务端、客户端、控制台与共享包在同一套发布流程下共同维护：提交必须签署 DCO、Pull Request 经过评审、以 `RELEASE.YYYY-MM-DDTHH-MM-SSZ` 标签发布，产物附带校验和、SPDX SBOM、Sigstore 签名清单与 GitHub 构建证明。每个版本都会在门户发布[版本说明](https://silo.pgsty.com/zh/tags/silo/)；安全问题按照 [`SECURITY.md`](SECURITY.md) 与仓库[安全公告](docs/security/advisories.md)处理。上游版权、许可证与第三方声明完整保留于 [`LICENSE`](LICENSE)、[`NOTICE`](NOTICE) 与 [`CREDITS`](CREDITS)。

 ## 兼容策略

 Silo 尽量保留：

- `minio` 可执行文件与 `github.com/minio/minio` module path；
- MinIO 兼容的 S3 API、配置、环境变量与命令行约定；
- `RELEASE.YYYY-MM-DDTHH-MM-SSZ` 标签、容器入口与常见部署方式。
+- `github.com/minio/minio` module path 与 `github.com/minio/*` 导入路径；
+- MinIO 兼容的 S3 API、线协议、`MINIO_*` 环境变量、指标、协议头、保留路由与存储元数据；
+- `RELEASE.YYYY-MM-DDTHH-MM-SSZ` 标签，以及容器入口对旧式 `minio …` 参数的转换。

-兼容性是默认约束。只要不会留下安全问题，Silo 就保留既有的协议、客户端、配置与运维行为；只有在修复重大安全问题确有必要时才会打破兼容，并在版本说明中明确受影响行为与迁移方式。每个版本仍应视为下游升级：锁定版本，阅读[版本说明](https://silo.pgsty.com/zh/blog/release/)与[安全公告](docs/security/advisories.md)，保留回滚路径，并在生产使用前完成测试。
+Silo 自有交付面统一使用 `silo` 可执行文件、软件包、服务、Helm Chart 与 `pgsty/silo` 容器镜像；原生交付物不会安装 `minio` 二进制别名。

+
+### 原生软件包迁移
+
+`silo` RPM、DEB 与 APK 不针对 `minio` 声明 `Provides`、`Obsoletes`、
+`Replaces` 或包级 `Conflicts`，因此可以与已有 MinIO 软件包并存安装，
+不会被普通升级静默替换。两个 systemd unit 在运行时互斥，应由管理员显式
+切换，不能同时启动。
+
+切换前请记录旧 unit 的 enabled/active 状态与 `User`/`Group`，并备份
+`/etc/default/minio`。Silo 先读取该旧配置，再读取 `/etc/default/silo`；后者
+中由管理员设置的同名变量优先。如现有数据必须继续使用原 UID/GID，请创建
+`/etc/systemd/system/silo.service.d/10-legacy-user.conf`：
+
+```ini
+[Service]
+User=<legacy-user>
+Group=<legacy-group>
+```
+
+执行 `systemctl daemon-reload`，先停用并停止 `minio.service`，再启用并启动
+`silo.service`。确认健康检查、S3、Admin API、指标与日志后，才 mask 或卸载
+旧服务。软件包迁移期间不要递归修改数据属主；在回滚观察窗口内保留旧包与
