+# Changelog
+
+## Unreleased
+
+The entries below describe source changes on main since the latest published Server.
+**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...main).
+
+### 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
+
+- Evaluate conditional multipart completion against the logical current object
+  across all pools while holding the existing object lock. A stale `If-Match`
+  can no longer replace newer data in another pool, and the current ETag is no
+  longer rejected because the upload resides next to an older copy. Conditions
+  are evaluated once; a current delete marker counts as an absent object.
+  **Availability change:** if metadata cannot be read from any pool, conditional
+  completion fails even when another pool can still serve GET/HEAD. This also
+  applies when the unreadable pool may not hold the object: absence cannot be
+  verified. Retry after the pool recovers. Unconditional completion and the
+  single-pool path retain their existing behavior.
+
+- Reconcile ordinary single-object version DELETE across all pools, including
+  null versions, delete markers and unqualified directory-marker DELETE. This
+  applies the deletion to every resolved pool copy under existing quorum
+  rules. Pending outbound delete replication retains versions until the
+  existing replication worker completes their purge; a successful response
+  does not imply immediate physical removal from every drive. Unreadable
+  pools now consistently return 503 instead of depending on pool traversal
+  order; insufficient read quorum returns `SlowDownRead`. This extends the
+  existing failure surface. Retry after recovery.
+  Cleanup failures also return an error. Batch deletion already fans out across
+  pools; replication and scanner cleanup keep their existing contracts. See
+  [scope and limitations](docs/bucket/lifecycle/access-tiering-removal.md#version-deletion-scope).
+
+- Remove the opt-in GET-frequency pool-tiering feature from PR #60, including
+  its tracker, mover, scanner hooks, configuration, XML actions and metrics.
+  Accept and ignore retired configuration/XML and preserve ordinary statistics
+  when reading v9 caches. See [migration notes](docs/bucket/lifecycle/access-tiering-removal.md).
+  The [decision record](docs/investigations/access-tiering-revert.md) preserves
+  the feature's introduction, subsequent fixes, rollback scope and review history.
+- Preserve the independent multi-pool write, metadata, healing and conditional
+  deletion fixes from PR #178, including shared remote-tier reference protection.
+- 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.
+
+## RELEASE.2026-09-03T13-18-01Z
+
+Published source: `9b11dc9469e650815b775cb47b039610644f5da4`.
+[Complete release notes](https://silo.pgsty.com/blog/release/silo-20260903/) ·
+[GitHub release](https://github.com/pgsty/silo/releases/tag/RELEASE.2026-09-03T13-18-01Z)
+
+This release ships Go 1.27.1, silo-pkg v3.13.2, upstream minio-go `0e78d3f18efe`,
+mcli 20260903 and embedded Console source `464a59d73ada` (v2.3.0 version identity).
+Installing the newer standalone mcli or Console does not replace components
+inside this existing Server binary or image.
+
+Earlier releases: [release archive](https://github.com/pgsty/silo/releases).

+# 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
+### Set up a checkout
-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).
 
 ```sh
-$ git clone https://github.com/minio/minio
+git clone https://github.com/pgsty/silo
-$ go install -v
+cd silo
-$ ls /go/bin/minio
+go build -o silo .
+./silo --version
 ```
 
-### Set up git remote as ``upstream``
+### Keep the lineage remote separate
+
 ```sh
-$ cd minio
+git remote add lineage https://github.com/minio/minio
-$ git remote add upstream https://github.com/minio/minio
+git fetch lineage
-$ git fetch upstream
-$ git merge upstream/master
-...
 ```
 
+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
+git checkout -b my-new-feature
 ```
 
-### Test MinIO server changes
+### Test Silo server changes
-After your code changes, make sure
 
-- 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.
+Before opening a pull request:
-- To run `make verifiers`
+
-- To squash your commits into a single commit. `git rebase -i`. It's okay to force update your pull request.
+- Add or update tests for changed behavior.
-- To run `make test` and `make build` completes.
+- 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'
 ```
 
 ### Push to the branch
+
 Push your locally committed changes to the remote origin (your fork)
+
 ```
-$ git push origin my-new-feature
+git push origin my-new-feature
 ```
 
 ### 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

 ## FAQs
-### How does ``MinIO`` manage dependencies?
+
-``MinIO`` uses `go mod` to manage its dependencies.
+### How does Silo manage dependencies?
+
+Silo uses Go modules. Preserve the compatibility module and import paths in
+`go.mod`; downstream forks are selected with explicit `replace` directives.
+
 - Run `go get foo/bar` in the source folder to add the dependency to `go.mod` file.
 
 To remove a dependency
+
 - Edit your code and remove the import reference.
 - Run `go mod tidy` in the source folder to remove dependency from `go.mod` file.
 
-### What are the coding guidelines for MinIO?
+### What are the coding guidelines?
-``MinIO`` is fully conformant with Golang style. Refer: [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) article from Golang project. If you observe offending code, please feel free to send a pull request or ping us on [Slack](https://slack.min.io).
+
+Follow the existing Go style, run `gofmt` on changed Go files, and keep changes
+compact. See the Go project's [code review comments](https://go.dev/wiki/CodeReviewComments).

+# Silo Pull Request Guidelines
+
+These guidelines ensure high-quality commits in Silo's GitHub repositories, maintaining
+a clear, valuable commit history for our open-source projects. They apply to all contributors,
+fostering efficient reviews and robust code.
+
+## Why Pull Requests?
+
+Pull Requests (PRs) drive quality in Silo's codebase by:
+- Enabling peer review without pair programming.
+- Documenting changes for future reference.
+- Ensuring commits tell a clear story of development.
+
+**A poor commit lasts forever, even if code is refactored.**
+
+## Crafting a Quality PR
+
+A strong Silo PR:
+- Delivers a complete, valuable change (feature, bug fix, or improvement).
+- Has a concise title (e.g., `[S3] Fix bucket policy parsing #1234`) and a summary with context, referencing issues (e.g., `#1234`).
+- Contains well-written, logical commits explaining *why* changes were made (e.g., “Add S3 bucket tagging support so that users can organize resources efficiently”).
+- Is small, focused, and easy to review—ideally one commit, unless multiple commits better narrate complex work.
+- Adheres to Silo's coding standards (e.g., Go style, error handling, testing).
+
+PRs must flow smoothly through review to reach production. Large PRs should be split into smaller, manageable ones.
+
+## Submitting PRs
+
+1. **Title and Summary**:
+   - Use a scannable title: `[Subsystem] Action Description #Issue` (e.g., `[IAM] Add role-based access control #567`).
+   - Include context in the summary: what changed, why, and any issue references.
+   - Use `[WIP]` for in-progress PRs to avoid premature merging or choose GitHub draft PRs.
+
+2. **Commits**:
+   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
+   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
+   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.
+
+3. **Testing**:
+   - Include unit tests for new functionality or bug fixes.
+   - Ensure existing tests pass (`make test`).
+   - Document testing steps in the PR summary if manual testing was performed.
+
+4. **Before Submitting**:
+   - Run `make verify` to check formatting, linting, and tests.
+   - Reference related issues (e.g., “Closes #1234”).
+   - Notify team members via GitHub `@mentions` if urgent or complex.
+
+## Reviewing PRs
+
+Reviewers ensure Silo's commit history remains a clear, reliable record. Responsibilities include:
+
+1. **Commit Quality**:
+   - Verify each commit explains *why* the change was made (e.g., “So that…”).
+   - Request rebasing if commits are unclear, redundant, or lack context (e.g., “Please squash typo fixes into the parent commit”).
+
+2. **Code Quality**:
+   - Check adherence to Silo's Go standards (e.g., error handling, documentation).
+   - Ensure tests cover new code and pass CI.
+   - Flag bugs or critical issues for immediate fixes; suggest non-blocking improvements as follow-up issues.
+
+3. **Flow**:
+   - Review promptly to avoid blocking progress.
+   - Balance quality and speed—minor issues can be addressed later via issues, not PR blocks.
+   - If unable to complete the review, tag another reviewer (e.g., `@username please take over`).
+
+4. **Shared Responsibility**:
+   - All Silo contributors are reviewers. The first commenter on a PR owns the review unless they delegate.
+   - Multiple reviewers are encouraged for complex PRs.
+
+5. **No Self-Edits**:
+   - Don’t modify the PR directly (e.g., fixing bugs). Request changes from the submitter or create a follow-up PR.
+   - If you edit, you’re a collaborator, not a reviewer, and cannot merge.
+
+6. **Testing**:
+   - Assume the submitter tested the code. If testing is unclear, ask for details (e.g., “How was this tested?”).
+   - Reject untested PRs unless testing is infeasible, then assist with test setup.
+
+## Tips for Success
+
+- **Small PRs**: Easier to review, faster to merge. Split large changes logically.
+- **Clear Commits**: Use `git rebase -i` to refine history before submitting.
+- **Engage Early**: Discuss complex changes in a GitHub issue before coding.
+- **Be Responsive**: Address reviewer feedback promptly to keep PRs moving.
+- **Learn from Reviews**: Use feedback to improve future contributions.
+
+## Resources
+
+- [Silo Contribution Guide](CONTRIBUTING.md)
+- [Effective Commit Messages](https://mislav.net/2014/02/hidden-documentation/)
+- [GitHub PR Tips](https://github.com/blog/1943-how-to-write-the-perfect-pull-request)
+
+By following these guidelines, we ensure Silo's codebase remains high-quality, maintainable, and a joy to contribute to. Happy coding!

+
+## Overview
+
+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.
+
+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/).
+
+**Related:** [`pgsty/mc`](https://github.com/pgsty/mc) client (shipped as `mcli`) · [`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)

+
+## Quick Start
+
+```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"
 ```
 
-The MinIO deployment starts using default root credentials `minioadmin:minioadmin`. You can test the deployment using the MinIO Console, an embedded
+<p align="center">
-object browser built into MinIO Server. Point a web browser running on the host machine to http://127.0.0.1:9000 and log in with the
+  <img src="https://silo.pgsty.com/images/silo-console/console-login.webp" alt="Silo Console">
-root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.
+</p>
 
-You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See
+Console on <http://localhost:9001>, S3 API on <http://localhost:9000>. The image bundles the client as `mcli`:
-[Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers,
-see https://docs.min.io/docs/ and click **MinIO SDKs** in the navigation to view MinIO SDKs for supported languages.
 
-> NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the `podman -v` option. For example, `-v /mnt/data:/data` maps the host OS drive at `/mnt/data` to `/data` on the container.
+```bash
-
+docker exec silo mcli alias set local http://127.0.0.1:9000 minioadmin change-me-long-password
-# macOS
+docker exec silo mcli mb local/demo && docker exec silo mcli ls local
-
-Use the following commands to run a standalone MinIO server on macOS.
-
-Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a *minimum* of 4 drives per MinIO server. See [MinIO Erasure Code Quickstart Guide](https://docs.min.io/docs/minio-erasure-code-quickstart-guide.html) for more complete documentation.
-
-## Homebrew (recommended)
-
-Run the following command to install the latest stable MinIO package using [Homebrew](https://brew.sh/). Replace ``/data`` with the path to the drive or directory in which you want MinIO to store data.
-
-```sh
-brew install minio/stable/minio
-minio server /data
 ```
 
-> NOTE: If you previously installed minio using `brew install minio` then it is recommended that you reinstall minio from `minio/stable/minio` official repo instead.
+> [!WARNING]
-
+> For production, pin a release, use unique credentials and TLS, monitor the service, keep independent backups, and test recovery. Start from the [documentation](https://silo.pgsty.com/docs/).
-```sh
+
-brew uninstall minio
+## Install
-brew install minio/stable/minio
+
-```
+| Method | Where |

-### ufw
+
-
+## Background
-For hosts with ufw enabled (Debian based distros), you can use `ufw` command to allow traffic to specific ports. Use below command to allow access to port 9000
+
-
+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.
-```sh
+
-ufw allow 9000
+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.
-Below command enables all incoming traffic to ports ranging from 9000 to 9010.
+- **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.
-```sh
+- **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.
-ufw allow 9000:9010/tcp

-```
-
-This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use
-
-```sh
-firewall-cmd --zone=public --add-port=9000/tcp --permanent

-
-Note that `permanent` makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.
-
-```sh
-firewall-cmd --reload

-
-### iptables
-
-For hosts with iptables enabled (RHEL, CentOS, etc), you can use `iptables` command to enable all traffic coming to specific ports. Use below command to allow
-access to port 9000
-
-```sh
-iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
-service iptables restart
-```
-
-Below command enables all incoming traffic to ports ranging from 9000 to 9010.
-
-```sh
-iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
-service iptables restart
-```
-
-## Pre-existing data
-When deployed on a single drive, MinIO server lets clients access any pre-existing data in the data directory. For example, if MinIO is started with the command  `minio server /mnt/data`, any pre-existing data in the `/mnt/data` directory would be accessible to the clients.
-
-The above statement is also valid for all gateway backends.
-
-# Test MinIO Connectivity
-
-## Test using MinIO Console
-MinIO Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure your server has started successfully.
-
-> NOTE: MinIO runs console on random port by default if you wish choose a specific port use `--console-address` to pick a specific interface and port.
-
-### Things to consider
-MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port *must* be accessible by the client for the redirection to work.
-
-For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
-
-For example, consider a MinIO deployment behind a proxy `https://minio.example.net`, `https://console.minio.example.net` with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set `MINIO_BROWSER_REDIRECT_URL` to `https://console.minio.example.net` to ensure the browser receives a valid reachable URL.
-
-Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable  and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.
-
-For example: `export MINIO_SERVER_URL="https://minio.example.net"`

-## Test using MinIO Client `mc`
-`mc` provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client [Quickstart Guide](https://docs.min.io/docs/minio-client-quickstart-guide) for further instructions.
-
-# Upgrading MinIO
-MinIO server supports rolling upgrades, i.e. you can update one MinIO instance at a time in a distributed cluster. This allows upgrades with no downtime. Upgrades can be done manually by replacing the binary with the latest release and restarting all servers in a rolling fashion. However, we recommend all our users to use [`mc admin update`](https://docs.min.io/docs/minio-admin-complete-guide.html#update) from the client. This will update all the nodes in the cluster simultaneously and restart them, as shown in the following command from the MinIO client (mc):
-
-```
-mc admin update <minio alias, e.g., myminio>
-```
-
-> NOTE: some releases might not allow rolling upgrades, this is always called out in the release notes and it is generally advised to read release notes before upgrading. In such a situation `mc admin update` is the recommended upgrading mechanism to upgrade all servers at once.
-
-## Important things to remember during MinIO upgrades
-
-- `mc admin update` will only work if the user running MinIO has write access to the parent directory where the binary is located, for example if the current binary is at `/usr/local/bin/minio`, you would need write access to `/usr/local/bin`.
-- `mc admin update` updates and restarts all servers simultaneously, applications would retry and continue their respective operations upon upgrade.
-- `mc admin update` is disabled in kubernetes/container environments, container environments provide their own mechanisms to rollout of updates.
-- In the case of federated setups `mc admin update` should be run against each cluster individually. Avoid updating `mc` to any new releases until all clusters have been successfully updated.
-- If using `kes` as KMS with MinIO, just replace the binary and restart `kes` more information about `kes` can be found [here](https://github.com/minio/kes/wiki)
-- If using Vault as KMS with MinIO, ensure you have followed the Vault upgrade procedure outlined here: https://www.vaultproject.io/docs/upgrading/index.html
-- If using etcd with MinIO for the federation, ensure you have followed the etcd upgrade procedure outlined here: https://github.com/etcd-io/etcd/blob/master/Documentation/upgrades/upgrading-etcd.md

+> **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)

+
+## 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。
+

+## 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。

 ## Reporting a Vulnerability
 
-All security bugs in [minio/minio](https://github,com/minio/minio) (or other minio/* repositories)
+For vulnerabilities in this fork:
-should be reported by email to security@min.io. Your email will be acknowledged within 48 hours,
-and you'll receive a more detailed response to your email within 72 hours indicating the next steps
-in handling your report.
 
-Please, provide a detailed explanation of the issue. In particular, outline the type of the security

+2. Prefer this repository's [private GitHub security advisory](https://github.com/pgsty/silo/security/advisories/new) workflow.
-you need access credentials for a successful exploit).
+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.
 
-If you have not received a reply to your email within 48 hours or you have not heard from the security team
+## Disclosure Process
-for the past five days please contact the security team directly:
-   - Primary security coordinator: aead@min.io
-   - Secondary coordinator: harsha@min.io
-   - If you receive no response: dev@min.io
 
-### Disclosure Process
+Fork-specific fixes and user-visible upgrade notes are published in [docs/security/advisories.md](docs/security/advisories.md). The fork-specific triage and remediation process is described in [VULNERABILITY_REPORT.md](VULNERABILITY_REPORT.md).
-
-MinIO uses the following disclosure process:
-
-1. Once the security report is received one member of the security team tries to verify and reproduce
-   the issue and determines the impact it has.
-2. A member of the security team will respond and either confirm or reject the security report.
-   If the report is rejected the response explains why.
-3. Code is audited to find any potential similar problems.
-4. Fixes are prepared for the latest release.
-5. On the date that the fixes are applied a security advisory will be published on https://blog.min.io.
-   Please inform us in your report email whether MinIO should mention your contribution w.r.t. fixing
-   the security issue. By default MinIO will **not** publish this information to protect your privacy.
-
-This process can take some time, especially when coordination is required with maintainers of other projects.
-Every effort will be made to handle the bug in as timely a manner as possible, however it's important that we
-follow the process described above to ensure that disclosures are handled consistently.
