+# Changelog
+
+## Unreleased — main as of 2026-09-13
+
+The coordinated source is merged through `5d955b5b7444f8a3ab550ce92713607998f89c0d`.
+**The latest published Server remains 20260903.** These changes are not in its
+binaries, packages or images. See the [component matrix](https://silo.pgsty.com/compatibility/versions/)
+and [complete commit range](https://github.com/pgsty/silo/compare/RELEASE.2026-09-03T13-18-01Z...5d955b5b7444f8a3ab550ce92713607998f89c0d).
+
+### Authorization and security
+
+- Reject unsigned `x-amz-*` request headers that could turn a signed PUT into a
+  copy of another object accessible to the signer (SN-2026-011). The latest
+  public Server is affected; the fix is on main. See [the advisory ledger](docs/security/advisories.md).
+- Align signed request fields with policy conditions and enforce header-only
+  presigned payload checksums. See [the signed-header review](https://silo.pgsty.com/blog/design/signed-header-coverage/).
+- **Breaking policy semantics:** separate self-service `admin:ChangeMyPassword`
+  from `admin:CreateUser`. Built-in read-only policies follow the split. Preserve
+  both denies if the previous combined restriction must survive upgrades or
+  rollback. Saved policies are not rewritten. Deploy with the matching Console
+  and pkg; see [the migration guide](docs/iam/password-permissions.md).
+
+### Object storage and replication
+
+- Add GET-frequency-based movement across pools, then preserve versions and
+  isolate writes during movement. Serialize and reconcile multi-pool object
+  writes, metadata updates, healing and conditional deletion; preserve shared
+  remote-tier references until their last local owner is removed.
+- Enforce `If-Match` on DELETE, preserve retention and independently ordered
+  Object Lock/tag updates, and correctly retransmit encrypted replicas.
+- Preserve plaintext part sizes and raw SSE-C replicas; prevent SSE-C
+  compression, honor key-rotation checksums, and complete attributes pagination.
+- Repair federated CopyObject checksums, destination timestamps, reserved
+  metadata, encrypted-object forwarding, legal hold and KMS context.
+- Make resync counters, target selection, cancellation and worker lifetimes
+  reflect actual work; complete delete-marker purges and report bounded MRF drops.
+- Converge bucket metadata with deterministic source state, deletion tombstones,
+  creation time recovery and diagnostics. The mixed-version export gate requires
+  coordinated upgrades before tombstones are exported. See [the #77 record](docs/investigations/issue-77-current.md).
+- Include per-bucket CORS in metadata export/import, close metadata publication
+  and logger races, and report effective bucket quotas in metrics.
+
+### Console, dependencies and delivery
+
+- Restore embedded Console login over loopback TLS, trusted-proxy handling and
+  all four WebSocket connection limits. Preserve Go TLS defaults across transports.
+- Directly require `github.com/pgsty/silo-pkg/v3` v3.14.0; select Console
+  `v0.0.0-20260913015128-417559bb2c97` and MC
+  `v0.0.0-20260913012246-4f609a4da3bb` with explicit PGSTY replacements.
+- Pin upstream minio-go `v7.3.1-0.20260910142817-60bd07042d49`; refresh Go x/*
+  modules and security fixes including bounded AMQP frame handling. Keep Go
+  1.27.1 and go-systemd v22.6.0's NetBSD compatibility replacement.
+- Refresh container base digests and build static curl 8.22.0 from verified
+  source for both Linux architectures. Pin the actual mcli 20260913 archives and
+  hashes. Helm's client image follows that release; its Server image still names
+  the latest published Server 20260903.
+
+The dependency update passed the final candidate's Go, vulnerability and Test
+Release workflows; native curl builds passed on both architectures. A local
+ARM64 image passed startup, health, S3 transfer and embedded Console checks.
+These checks do not publish a Server tag or production image and do not replace
+cluster upgrade/rollback acceptance for the next release. Dated investigations
+retain the exact source and runtime boundaries they tested.
+

 # 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`.
+- If `make rebrand-guard` reports a changed compatibility set, review the
+  listed identifiers; when the change is intended, refresh the baseline with
+  `go run ./buildscripts/rebrand-guard --write` and commit
+  `buildscripts/rebrand-guard/compat-baseline.json`.
+- 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
+
+Code contributions to PGSTY SILO (`pgsty/silo`) are accepted under the
+[GNU AGPL v3.0 or later](LICENSE), the same license as the server. Submit issues
+and pull requests to this repository's maintainers. No separate Apache-2.0
+license grant to SILO or upstream MinIO maintainers is required.
+
+* **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.** Preserve existing copyright and license notices in inherited
+  and third-party files. New original files name their actual copyright holders
+  and use AGPL-3.0-or-later. Use a header such as the following, then append the
+  standard AGPL boilerplate:
+
+  ```
+  // Copyright (c) 2026 Your Name
+  ```
+
+* **Separately licensed material.** Documentation contributions in `docs/`
+  follow its existing [CC BY 4.0 license](docs/LICENSE). Third-party components
+  and earlier Apache-2.0 contributions retain their original licenses and
+  attribution; this policy does not relicense earlier work.
+
+* **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.

-Ansible Deployment: [https://pigsty.io/docs/minio](https://pigsty.io/docs/minio)
+PGSTY SILO keeps one maintained release line of the open-source MinIO server alive after upstream ended community distribution: builds, packages, multi-arch images, security fixes, and the full web console. Pigsty runs it in production as its PostgreSQL backup repository.

-APT/YUM repo for `minio` and `mcli` binary: [https://pigsty.io/docs/infra](https://pigsty.io/docs/repo/infra/list/#object-storage)
+It follows one rule — **the product and its delivery surfaces are renamed; the protocol and your data are not.** Everything else lives on [silo.pgsty.com](https://silo.pgsty.com/).

+## Install
+
+| Method | Where |
+| :-- | :-- |
+| Container | [`pgsty/silo`](https://hub.docker.com/r/pgsty/silo), multi-arch for `linux/amd64` and `linux/arm64` |
+| Binaries | [GitHub Releases](https://github.com/pgsty/silo/releases) — Linux, macOS, Windows on `amd64` and `arm64` |
+| Packages | RPM, DEB, and APK, also via the [Pigsty repository](https://pigsty.io/docs/repo/) |
+| Kubernetes | Helm chart, see [Download & Install](https://silo.pgsty.com/download/) |
+| Source | `go build -o silo . && ./silo --version` |
+
+Every release ships checksums, SPDX SBOMs, Sigstore-signed manifests, and GitHub build attestations. Installation methods and verification commands are documented at [Download & Install](https://silo.pgsty.com/download/); migrating from upstream MinIO — taking over an existing `minio.service` and its `/etc/default/minio`, and keeping data ownership stable with a `/etc/systemd/system/silo.service.d/10-legacy-user.conf` drop-in — is covered by the [migration guide](https://silo.pgsty.com/compatibility/migration/) and the [binary & service notes](https://silo.pgsty.com/compatibility/binary/).
+
+## Compatibility
+
+The S3 API, `MINIO_*` variables, `minio_*` metrics, `x-minio-*` headers, `/minio/*` routes, the `github.com/minio/*` import paths, and the on-disk format (including `.minio.sys`) are preserved and held in place by a CI compatibility check. Only Silo-owned delivery surfaces change: the `silo` executable, package, service, Helm chart, and container image — no `minio` binary alias is installed.
+
+Every divergence from upstream is listed in the code-verified [compatibility audit](https://silo.pgsty.com/compatibility/server/). Treat each release as a downstream upgrade: pin versions, read the [release notes](https://silo.pgsty.com/tags/silo/), and keep a rollback path.
+
+### TLS and Go upgrades
+
+TLS key exchange follows Go's defaults across the S3 listener, node links,
+replication, identity providers, etcd, and external HTTP services. If an endpoint
+cannot accept ML-KEM, `GODEBUG=tlsmlkem=0` disables the default hybrid exchanges
+for the process; certificate verification remains enabled. This option does not
+disable ML-DSA signatures or resolve every TLS reset. Prefer updating the
+incompatible endpoint before removing the temporary setting.
+If only the new SecP hybrids cause problems, `GODEBUG=tlssecpmlkem=0` disables
+those groups while retaining X25519MLKEM768.
+
+For builds targeting Go 1.27, setting either `SSL_CERT_FILE` or `SSL_CERT_DIR`
+on macOS replaces Keychain trust with on-disk roots and Go's verifier. Stale or
+incomplete CA paths can break previously trusted connections; unset inherited
+values to restore Keychain trust. Explicit certificates in the configured `CAs`
+directory remain additive to the selected root pool.
+Go 1.27 binaries require macOS 13 or later. See the
+[Go release notes](https://go.dev/doc/go1.27) and the
+[SILO stack investigation](docs/investigations/go127-stack.md).

+
+## Background
+
+Upstream wound down its community edition: the web console was cut back to a stub, prebuilt community binaries stopped, and the community repository was archived. Silo exists to keep those deployments running. The fork is a means, not an identity — if upstream restores its community edition, we will narrow our scope and offer the fixes back.
+
+The [**Manifesto**](https://silo.pgsty.com/about/manifesto/) is the project's public commitment in eleven articles, under one discipline: every article is either something already done with public evidence, or something explicitly refused. In short:
+
+- **Compatibility contract** — the protocol and your data do not change, and every release documents its tested rollback target and path.
+- **The license cannot change** — AGPLv3, no CLA, no copyright aggregation; nobody here, ourselves included, holds enough copyright to relicense on everyone else's behalf.
+- **The never list**, append-only — no paywalling existing features, no registration wall on downloads, no telemetry (upstream's phone-home paths are removed outright), no CLA, no license change, no trademark enforcement against normal use.
+- **Security and release discipline** — a public advisory for every fix, and a release every one to two months, at most a quarter apart. Judge both against the public record.

+
+> [!IMPORTANT]
+> **PGSTY Silo**（以下简称 Silo）是由 [Pigsty](https://pigsty.cc) 独立维护、从 [`pgsty/silo`](https://github.com/pgsty/silo) 发布的开源 MinIO 社区分支。本项目与 MinIO, Inc. 不存在隶属、背书或赞助关系；文中使用 “MinIO” 仅用于说明上游项目及兼容谱系。
+
+> [!NOTE]
+> 2026-08-06，本仓库由 `pgsty/minio` 更名为 `pgsty/silo`，默认分支由 `master` 更名为 `main`。以原 MinIO 形态维持的归档构件仍位于归档的 [`minio`](https://github.com/pgsty/silo/tree/minio) 分支，以及截止 [`RELEASE.2026-08-04T00-00-00Z`](https://github.com/pgsty/silo/releases/tag/RELEASE.2026-08-04T00-00-00Z) 的历次发布中。
+
+## 当前发行版与主分支
+
+最新已发布的 Server 仍为 [20260903](https://github.com/pgsty/silo/releases/tag/RELEASE.2026-09-03T13-18-01Z)。
+截至 2026-09-13，主分支已合入更新的安全、存储、Console 与共享包改动，但尚未发布新 Server。
+准确的已发布/源码边界见 [CHANGELOG.md](CHANGELOG.md) 与[组件版本矩阵](https://silo.pgsty.com/zh/compatibility/versions/)，
+其中包括 SN-2026-011 修复状态与密码权限迁移要求。
+
+## 概述
+
+上游停止社区发行后，Silo 为开源 MinIO 服务端维护一条持续可用的版本线：构建、软件包、多架构镜像、安全修复与完整 Web 控制台。Pigsty 在生产环境中用它承载 PostgreSQL 备份存储。
+
+它只遵循一条原则：**改名的是产品与交付物，不是协议与你的数据。** 其余内容都在 [silo.pgsty.com](https://silo.pgsty.com/zh/)。
+
+**相关项目：**[`pgsty/mc`](https://github.com/pgsty/mc) 客户端（以 `mcli` 发行） · [`pgsty/silo-console`](https://github.com/pgsty/silo-console) · [`pgsty/silo-pkg`](https://github.com/pgsty/silo-pkg) · [`pgsty/pigsty`](https://github.com/pgsty/pigsty)

+</p>
+
+## 快速上手
+
+```bash
+docker run -d --name silo -p 9000:9000 -p 9001:9001 \
+  -e MINIO_ROOT_USER=minioadmin \
+  -e MINIO_ROOT_PASSWORD=change-me-long-password \
+  -v "$PWD/data:/data" \
+  docker.io/pgsty/silo:latest server /data --console-address ":9001"
+```
+
+<p align="center">
+  <img src="https://silo.pgsty.com/images/silo-console/console-login.webp" alt="Silo 控制台">
+</p>
+
+控制台位于 <http://localhost:9001>，S3 API 位于 <http://localhost:9000>。镜像内置客户端 `mcli`：
+
+```bash
+docker exec silo mcli alias set local http://127.0.0.1:9000 minioadmin change-me-long-password
+docker exec silo mcli mb local/demo && docker exec silo mcli ls local
+```
+
+> [!WARNING]
+> 生产环境应锁定版本，使用独立凭据与 TLS，配置监控，保留独立备份，并验证恢复流程。请从[文档](https://silo.pgsty.com/zh/docs/)开始。
+
+## 安装
+
+| 方式 | 位置 |
+| :-- | :-- |
+| 容器镜像 | [`pgsty/silo`](https://hub.docker.com/r/pgsty/silo)，支持 `linux/amd64` 与 `linux/arm64` |
+| 二进制 | [GitHub Releases](https://github.com/pgsty/silo/releases)，覆盖 Linux、macOS、Windows 的 `amd64` 与 `arm64` |
+| 软件包 | RPM、DEB、APK，也可通过 [Pigsty 软件仓库](https://pigsty.cc/docs/repo/) 安装 |
+| Kubernetes | Helm Chart，参见[下载与安装](https://silo.pgsty.com/zh/download/) |
+| 源码构建 | `go build -o silo . && ./silo --version` |
+
+每个版本都附带校验和、SPDX SBOM、Sigstore 签名清单与 GitHub 构建证明。完整安装方式与验证命令见[下载与安装](https://silo.pgsty.com/zh/download/)；从上游 MinIO 迁移 —— 接管既有 `minio.service` 与 `/etc/default/minio`，并用 `/etc/systemd/system/silo.service.d/10-legacy-user.conf` drop-in 保持数据属主不变 —— 见[迁移指南](https://silo.pgsty.com/zh/compatibility/migration/)与[二进制与服务说明](https://silo.pgsty.com/zh/compatibility/binary/)。
+
+## 兼容性
+
+S3 API、`MINIO_*` 环境变量、`minio_*` 指标、`x-minio-*` 头、`/minio/*` 路由、`github.com/minio/*` 导入路径与磁盘格式（含 `.minio.sys`）原样保留，并由 CI 兼容性门禁冻结。只有 Silo 自有交付面改名：`silo` 可执行文件、软件包、服务、Helm Chart 与容器镜像 —— 原生交付物不会安装 `minio` 二进制别名。
+
+与上游的全部分歧，以逐项核验代码的[兼容性审计](https://silo.pgsty.com/zh/compatibility/server/)形式维护。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/tags/silo/)，并保留回滚路径。
+
+## 安全与贡献
+
+请按照 [`SECURITY.md`](SECURITY.md) 私密报告漏洞；每项修复都会发布公开[安全公告](https://silo.pgsty.com/zh/blog/security/)。本项目不要求签署 CLA：贡献按 AGPL-3.0-or-later（inbound=outbound）接收，只需 DCO 签署（`git commit -s`），详见 [`CONTRIBUTING.md`](CONTRIBUTING.md)。

+## 背景
+
+本项目因上游收缩社区版而生：Web 控制台被削减为残桩、社区预编译制品停发、社区仓库被归档。Silo 的存在就是让这些部署继续跑下去。Fork 是手段，不是身份 —— 若上游恢复社区版承诺，我们乐意收缩范围，并把修复回馈上游。
+
+[**宣言**](https://silo.pgsty.com/zh/about/manifesto/)是项目的公开承诺，共十一条，通篇遵循一项纪律：**每一条，要么是已经在做且有公开证据的事实，要么是刻意拒绝的承诺。** 摘要：
+
+- **兼容性合同** —— 协议与数据不改，每个版本都标注经过测试的回滚目标与路径。
+- **许可证无法变更** —— AGPLv3、无 CLA、不做版权聚合；包括我们自己在内，没有人握有足够版权代表所有贡献者重新授权。
+- **永不清单**（只增不减）—— 永不将既有功能移入付费墙、永不给下载设注册墙、永不加入遥测（上游回连路径已整体移除）、永不引入 CLA、永不变更许可证、永不以商标追究正常使用。
+- **安全与发布纪律** —— 每项安全修复配一篇公开公告；通常每一到两个月发布一版，最长不超过一个季度。请拿公开记录检验这两条。

 # Security Policy

-This repository is the `pgsty/minio` community fork of `minio/minio`. Upstream MinIO security contacts do not handle fork-specific fixes or release notes for this repository.
+Silo is an independent, community-maintained object-storage server derived from
+the open-source MinIO server. Upstream MinIO security contacts do not handle
+Silo-specific fixes or release notes.

 ## Supported Versions

-Security fixes are tracked on the active `master` branch and summarized in [docs/security/advisories.md](docs/security/advisories.md).
+Security fixes are tracked on the active development branch and summarized in

+## Inherited Fix Evidence
+
+The canonical ledger also records security fixes inherited from upstream when
+they are part of the Silo release baseline. Source and fork commits are linked

 ## Reporting a Vulnerability

 For vulnerabilities in this fork:

 1. Follow the fork-specific expectations in [VULNERABILITY_REPORT.md](VULNERABILITY_REPORT.md).
-2. Prefer the `pgsty/minio` repository's GitHub security reporting workflow when it is available.
-3. If private reporting is not available, contact the maintainers through the `pgsty/minio` repository before publishing detailed exploit information.
+2. Prefer this repository's [private GitHub security advisory](https://github.com/pgsty/silo/security/advisories/new) workflow.
+3. If private reporting is unavailable, contact the maintainers through the
+   repository without publishing exploit details until a private channel is
+   established.
 4. If you confirm the issue also affects upstream `minio/minio`, report it upstream separately.
