+# SILO Repository Guide
+
+## Project map
+
+- Server: `pgsty/silo` (this checkout, default branch `main`)
+- Console: `pgsty/silo-console` (usual sibling checkout `../silo-console`)
+- Client: `pgsty/mc`, shipped as `mcli` (usual sibling checkout `../mc`)
+- Shared packages: `pgsty/silo-pkg` (usual sibling checkout `../silo-pkg`)
+- Documentation: `pgsty/silo.pgsty.com` (usual sibling checkout `../silo.pgsty.com`),
+  published at <https://silo.pgsty.com/>
+
+The server executable, package, systemd service, and container image use `silo`;
+the public Docker image is `docker.io/pgsty/silo`. The server module remains
+`github.com/minio/minio`. Consult the current `go.mod` and release configuration
+for selected component versions and compatibility replacements.
+
+## Supported stack and compatibility policy
+
+The maintained, release-gating product graph is the coordinated PGSTY stack:
+`silo` + `silo-console` + `mc` + `silo-pkg`.
+
+Keep compatibility with upstream MinIO/MC on a best-effort basis. Preserve
+inexpensive wire, configuration, CLI, migration, and import compatibility when
+it helps users, and document known differences. Do not infer from source
+lineage, MinIO-compatible protocols, retained `MINIO_*`/`MC_*` names, or an
+inherited upstream test that unmodified upstream MinIO is a supported release
+target.
+
+Upstream-only compatibility checks may remain as advisory evidence, but they
+must not force a downgrade of a maintained SILO component, a fork-only API
+workaround, or a release block. Make upstream compatibility a hard gate only
+when the user explicitly requests that scope.
+
+## Dependency selection
+
+- When PGSTY maintains a component, import and require it directly under its own
+  module path. In particular, prefer `github.com/pgsty/silo-pkg/v3` over
+  `github.com/minio/pkg/v3` in maintained SILO source.
+- Do not use an upstream package merely to make unmodified upstream MinIO or MC
+  compile. Unavoidable transitive upstream modules should be documented and
+  kept separate from the maintained product dependency.
+- `github.com/minio/minio-go/v7` is the explicit exception: use the verified
+  upstream module/commit while it contains the required fixes; do not recreate
+  a SILO fork without a concrete functional divergence.
+- Check the current `go.mod` before changing versions. Coordinate breaking
+  import-path changes across package, client, Console, and server releases.
+
+## Documentation and delivery
+
+The companion site owns product, operations, migration, security-advisory,
+design, and release documentation. Maintain English and Chinese content in
+that repository and link to its canonical URLs from this one. The site's
+`content/docs/` is the documentation entry point; detailed pages live under
+`content/operations/`, `administration/`, `reference/`, `compatibility/`,
+`about/`, and `blog/`, following the existing structure.
+
+Keep repository entry points and contributor instructions here. Retained
+upstream documents, examples, and test fixtures under `docs/` may be updated
+when a code or tooling change requires it; do not build a second documentation
+site in this tree.
+
+Investigation plans, prompts, AI session transcripts, execution logs, temporary
+reports, and private security material belong outside the checkout, for example
+in a task-specific directory under `~/tmp/`. Do not recreate
+`docs/investigations/`, `docs/security/`, or `docs/rebranding.md`, or move their
+working material to another repository directory. Extract reusable, verified
+knowledge into the companion site; keep private evidence outside public Git.
+
+Compatibility pages may continue to describe similarities with upstream, but
+must label that compatibility as best effort. The supported and tested server
+for Console and mcli administration is `pgsty/silo`.
+
+Before removing or moving documentation, check repository links and scripts,
+the companion site's links and anchors, and references from this guide. Use
+fixed commit URLs for historical evidence that should survive deletion from
+the current tree. Run the site's `make check` for site changes and this
+repository's `make rebrand-guard` for documentation cleanup that changes the
+identifier inventory. When new public URLs are involved, publish the site
+before publishing source changes that depend on those URLs.

+
+## Unreleased
+
+Preparation target: `RELEASE.2026-09-16T00-00-00Z` (package version
+`20260916000000.0.0`). The entries below describe the candidate changes 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
+
+- Synchronize CPU metrics reads with resource-metrics updates (#210), preventing
+  concurrent map access from terminating the server during Prometheus scraping.
+  Metric names, values and authentication requirements are unchanged.
+- Restrict embedded Console's anonymous sharing proxy to object-content GETs
+  at the configured S3 origin, and reject every redirect. Internal metrics,
+  system paths and non-download S3 operations cannot be reached through it.
+  Normal public, presigned and versioned downloads remain available without a
+  new setting; a full sharing-disable switch is not introduced. See
+  [Console #56](https://github.com/pgsty/silo-console/pull/56) and the
+  [design record](https://github.com/pgsty/silo-console/issues/52).
+  Thanks to Jiri Pejchal (@jiri-pejchal) for the report.
+- Persist IAM deletion revisions and parent revocation boundaries so stale site
+  events cannot restore deleted identities, policies or their older grants
+  (#191, #192). Peer deletion notifications reload committed storage; deliberate
+  recreation requires a newer revision, and credentials issued before the
+  parent's revocation remain invalid.
+  **Coordinated upgrade required:** upgrade every participating node and site.
+  Mixed old/new nodes sharing an IAM backend and rolling downgrade are
+  unsupported. Back up complete IAM storage and encryption material; an admin
+  export of live records omits deletion history. Reissue credentials for
+  recreated parents and explicitly reconcile pre-upgrade revocations whose
+  history is already lost. Restoring an older backup can lose later revocations;
+  keep affected sites isolated until reconciliation/rekeying is complete. See
+  [the operator runbook](https://silo.pgsty.com/operations/replication/iam-upgrade/).
+- Enforce an absolute HTTP/1 request-header deadline through the connection
+  wrapper (#196). Repeated small reads no longer extend that deadline, and
+  `--read-header-timeout` / `MINIO_READ_HEADER_TIMEOUT` now reaches the HTTP
+  server. HTTP/1 request bodies retain the rolling idle timeout; this does not
+  impose a total upload/download duration. A shorter setting also constrains
+  TLS handshake reads. The wrapper's strict header mode is not applied to HTTP/2.
+- 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](https://silo.pgsty.com/about/security-advisories/).
+- 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
+
+- Make `ListMultipartUploads` discover quorum-valid uploads from durable state
+  across pools, erasure sets and drives, then apply S3 prefix, delimiter,
+  marker, ordering and 1,000-entry pagination semantics globally (#198). New uploads
+  store their canonical bucket and key as reserved fields in the existing
+  quorum-written `xl.meta`; completion removes those upload-only fields. Native
+  markers remain usable after their upload is completed or canceled. Strict
+  listing returns a diagnostic 503 for legacy uploads or uncertain coverage;
+  the default remains the released exact-key/cache-based `legacy` behavior.
+  Opt into strict mode only through `MINIO_API_MULTIPART_LISTING=strict`, after
+  upgrading every writer, draining old uploads, checking the read-only admin
+  `multipart-preflight` report and validating scan capacity. The process-only
+  setting is not persisted into shared API configuration. Historical
+  `multipart_listing` keys are ignored and can be removed with a targeted
+  `mcli admin config reset ALIAS api multipart_listing` before rollback. Per-process
+  admission, directory-entry, worker and time budgets bound scan scheduling;
+  each page still scans durable state. See [issue #79](https://github.com/pgsty/silo/issues/79)
+  and its [design record](https://silo.pgsty.com/blog/design/list-multipart-uploads/).
+  Thanks to mr javad seydi (@mrjavadseydi) for the original implementation.
+- Retain released read-quorum and best-effort multipart cancellation in default
+  legacy mode. Strict mode requires majority deletion acknowledgements and
+  permits retries below read quorum. When most drives were already empty,
+  failed deletion of an observed remnant now returns 503 instead of being
+  masked by empty-drive successes. Wrong-key or wrong-bucket cancellation
+  preserves the valid upload's cache entry; successful cancellation notifies
+  peers with the request context after the distributed lock is released.
+  The HTTP response for an absent
+  upload remains 204; this is not proof of physical cleanup. **Known boundary:**
+  delayed creation writes can still restore an upload after cancellation;
+  this change does not add a durable creation fence.
+- Preserve object tags during multi-pool metadata reconciliation by reading the
+  resolved tag field together with its revision (#189). Previously, reconciliation
+  could replace existing tags with an empty value.
+- Preserve the tag revision on SSE-KMS metadata replication (#193), and advance
+  tag revisions monotonically on local PUT/DELETE tagging (#196). Empty tags
+  participate in reconciliation as an ordered deletion, preventing older
+  events from restoring removed tags. SSE-C key rotation also retains the tag
+  revision. Malformed historical revisions can fail and retry; their missing
+  history is not reconstructed by the upgrade.
+- Complete delete-marker version purges and preserve their identity and retry
+  state through MRF recovery (#196). Recovery accepts a 405 marker response only
+  when its version, bucket, object name and modification time match the task.
+  Purge audit status is normalized from `COMPLETE` to `COMPLETED`.
+  Thanks to Julien Laurenceau (@julienlau) for the investigation and proposed
+  fix in #184 that helped shape this follow-up.
+- Restore only the six replication-specific metadata fields after ordinary
+  request metadata extraction (#194). This prevents transport-only `aws-chunked`
+  from being stored as Content-Encoding while preserving the signed-header
+  protections. Trusted Snowball entries no longer inherit the outer archive's
+  ordinary metadata. Thanks to Mikhail Khadarenka (@chodorenko) for the fix in #187.
+  **Existing data:** these repairs prevent new errors; they do not scan or rewrite
+  historical object metadata, recover lost tags or prove that old purge work has
+  converged. Follow the [read-only audit procedure](https://silo.pgsty.com/operations/replication/replica-metadata-audit/)
+  before planning any repair of stored state.
+
+- Make exact-version delete-marker purges converge in replicated buckets
+  (`eb4f5e5b3`, `254b19ac0`, `358ab38fb`). A purge no longer creates the
+  marker on drives that lacked it; a retried purge of a missing version is
+  acknowledged only when a write-quorum majority of drives report it absent;
+  purge results merge removed and reliably absent replies; healing a marker
+  preserves its stored replication and purge metadata; and a queued marker
+  creation is re-checked against the source under the replication lock before
+  it is sent, so a purge that already reached the targets is not undone by a
+  stale task from another frontend, a GET/LIST heal, the scanner or MRF.
+  Purging a data version whose earlier purge is still pending reports it as a
+  data version. **Known limitations:** creations already in flight or replayed
+  from another site, and minority marker copies left by a crash after a
+  majority-acknowledged purge, are tracked in #217. See
+  [the replication reliability record](https://silo.pgsty.com/blog/design/replication-reliability/).
+- Keep a null object version that has listing quorum when a newer minority of
+  drives sorts first (`8d06424b1`). The resolver recounts per header only when
+  the original selection lacks quorum, every non-empty drive stream holds
+  exactly one ordinary null version and all share the same erasure layout;
+  mixed histories keep their previous behavior. **Known limitation:** a
+  successful ListObjects can still omit readable keys during rolling restarts
+  with concurrent overwrites (#218). Do not run destination-deleting sync tools
+  against a listing taken during a rolling restart; list again once the
+  cluster is stable.
+- Carry object tags through rebalance and decommission for ordinary and
+  multipart writes (`fced86303`). Both migration entry points restore the tags
+  and their revision fields when rewriting the object in the destination pool.
+  Tags dropped by earlier migrations are not recovered; audit tag-dependent
+  lifecycle and policy rules for pools migrated with an older build.
+
+- 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 any pool's metadata cannot be read, 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.
+
+- Evaluate ordinary multi-pool conditional PUT against the logical current
+  object across all pools, including draining pools, under the existing object
+  lock (#207). A stale destination copy no longer accepts a stale ETag or rejects
+  the current one; a current delete marker is treated as absence.
+  **Availability change:** if any pool's object metadata cannot be verified,
+  the condition fails even when GET can use another pool; read-quorum failures
+  return 503. Restore readability or heal before retrying. Unconditional PUT,
+  single-pool conditions and internal replication retain their existing behavior.
+  A public condition with a destination `versionId` compares the current object
+  while preserving the requested write version. This change does not retire
+  stale copies in other pools, undo historical accepted overwrites or provide
+  a new global clock-ordering guarantee. The multipart-completion repair in #190
+  neither introduced nor repaired this separate PUT defect.
+
+- 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](https://silo.pgsty.com/compatibility/access-tiering-removal/) 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, 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](https://silo.pgsty.com/blog/design/bucket-metadata-convergence/).
+- 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` v3.14.1; select released Console
+  v2.4.1 (`v0.0.0-20260916075814-1360e26d976d`) and mcli 20260916
+  (`v0.0.0-20260916070421-e952aa78f10a`) with explicit PGSTY replacements.
+  The embedded frontend identifies itself as Console v2.4.1.
+- Pin upstream minio-go `v7.3.1-0.20260915093545-32e1f32cb176` to handle
+  CopyObject errors embedded in HTTP 200 responses. Update JWX to v3.3.0 for
+  JSON field-name escaping, strfmt to v0.27.2 for Go 1.27 hostname validation,
+  and LZ4 to v4.1.30 for frame-reader, partial-read and concurrency fixes.
+  Retain the earlier Go x/* and bounded AMQP frame updates, 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 published mcli 20260916 archives
+  and hashes in the container and update the client installer default.
+- Prepare Helm chart 7.0.3 with Server and client defaults for the September 16
+  batch. Publish the chart only after the corresponding Server image exists.
+- Pin GoReleaser v2.18.1 and its action commit identically in snapshot and release
+  workflows. Dependency-only PRs now run the Test Release Pipeline too.
+
+Validation of earlier source revisions does not establish acceptance of this
+candidate. Final source, package, image and multi-process checks are tracked
+separately in [#203](https://github.com/pgsty/silo/issues/203). No Server release
+or production rollout is implied by this preparation target.

 # 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.

+# 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 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.

+## Contributor recognition
+
+Every human issue or pull-request author is recognized in [CONTRIBUTORS.md](CONTRIBUTORS.md),
+including open issues, draft PRs, and PRs closed without merging. Merged fixes,
+adopted proposals, and reports that lead to fixes receive greater prominence;
+first participation guides the remaining order. Work incorporated through a
+later PR retains credit without changing the original PR's recorded status.
+Security disclosures are credited with the reporter's agreement. DCO sign-off
+applies to code commits, not to opening an issue.
+
+## 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.

+
+<!-- Generated by silo.pgsty.com/bin/contributors.py. -->
+
+As of **2026-09-16**, **50 community contributors** are credited in SILO and related projects. The roll includes maintainers and every human issue / PR author, plus the previously acknowledged security disclosure.
+
+Opening an issue or PR counts, whether open, closed, draft, or unmerged. Each account appears once. Merged PR authors come first, followed by other PR authors and reporters. Within each group, significant fixes, adopted proposals, and reports that led to fixes take priority, followed by first participation. Gold rings highlight significant contributions.
+
+When a proposal was incorporated through a later repair, its adoption is credited separately from the original PR status. A closed issue does not necessarily mean a fix, and merged source does not imply a published release. Automated accounts are excluded. Upstream authorship remains in Git history and copyright notices.

 ## 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.
+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.

-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/).
+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/).

-
-## Maintenance Policy
-
-The active release line covers:
-
- build and dependency maintenance;
- applicable security fixes and advisories;
- focused fixes for reproducible defects;
- versioned binaries, packages, checksums, and multi-architecture images;
- the web console, client, documentation, and Pigsty integration.
-
-Changes are kept narrow and tested where practical. Maintenance is best effort; no response, remediation, or release schedule is guaranteed.
-
-### Out of scope
-
- a separate product roadmap, new storage engine, or speculative S3 features;
- broad rewrites or changes that materially expand the downstream delta;
- historical releases or multiple support branches;
- commercial support, SLAs, 24×7 coverage, or SUBNET access;
- deployment design, access control, monitoring, backup, or recovery.
-
-## 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.
-
-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.
-
-## Downloads and Release Artifacts
-
-Use [Download & Install](https://silo.pgsty.com/download/) to choose an installation method. GitHub Releases remains the source for versioned server binaries, checksums, and source archives.

 ## Quick Start

-For local evaluation:
-
 ```bash
-mkdir -p data
-
-export MINIO_ROOT_USER=minioadmin
-export MINIO_ROOT_PASSWORD=change-me-long-password
-
-docker run -d --name silo \
-  -p 9000:9000 \
-  -p 9001:9001 \
-  -e MINIO_ROOT_USER \
-  -e MINIO_ROOT_PASSWORD \
+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" \
-  pgsty/minio:latest server /data --console-address ":9001"
+  docker.io/pgsty/silo:latest server /data --console-address ":9001"
 ```

-Open the console at <http://localhost:9001>; the S3 API listens on <http://localhost:9000>.
+<p align="center">
+  <img src="https://silo.pgsty.com/images/silo-console/console-login.webp" alt="Silo Console">
+</p>

-The image includes the compatible client as `mcli`:
+Console on <http://localhost:9001>, S3 API on <http://localhost:9000>. The image bundles the client as `mcli`:

 ```bash
-docker exec silo mcli alias set local http://127.0.0.1:9000 \
-  "$MINIO_ROOT_USER" "$MINIO_ROOT_PASSWORD"
-docker exec silo mcli mb local/demo
-docker exec silo mcli ls local
+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]
-> For production, pin a release, use unique credentials and TLS, monitor the service, keep independent backups, and test recovery.
+> 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/).

-Build the server from source:
+## Install

-```bash
-go build -o minio .
-./minio --version
-```
+| 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` |

-For other installation paths—including native packages, binaries, Podman, Kubernetes, source, and Pigsty Ansible—use [Download & Install](https://silo.pgsty.com/download/). For production deployment and administration, start with the [Silo documentation](https://silo.pgsty.com/docs/). Pigsty users can also use the [Pigsty MinIO module](https://pigsty.io/docs/minio/).
+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/).

-## Security
+## Compatibility

-Security fixes target the active `master` branch and are recorded in the [advisory log](docs/security/advisories.md) and the portal's [security notes](https://silo.pgsty.com/blog/security/). Report vulnerabilities privately as described in [`SECURITY.md`](SECURITY.md) and [`VULNERABILITY_REPORT.md`](VULNERABILITY_REPORT.md). Report issues that also affect upstream MinIO there as well.
+Silo preserves S3 and storage-format compatibility, including existing `MINIO_*` variables, `minio_*` metrics, `x-minio-*` headers, `/minio/*` routes, and `.minio.sys` data. CI guards selected compatibility identifiers; release notes document intentional security and behavior changes. Silo-owned delivery surfaces use the `silo` executable, package, service, Helm chart, and container image; no `minio` server binary alias is installed.

-## Contributing
+The supported release stack is `pgsty/silo` + `pgsty/silo-console` + `pgsty/mc` + `pgsty/silo-pkg`; compatibility with unmodified upstream MinIO/MC is best effort. The Server, Console, and client retain their historical module paths where needed, while maintained code imports `github.com/pgsty/silo-pkg/v3` directly. The SDK `github.com/minio/minio-go/v7` is an explicit upstream dependency. See the current [go.mod](go.mod) for versions and replacements.

-Useful contributions include security and dependency updates, reproducible bug fixes, tests, release automation, packaging, and documentation.
+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.

-Issues and pull requests should include the affected version, reproduction steps, impact, expected behavior, tests, and compatibility notes. Discuss large changes in an issue first.
+### TLS and Go upgrades
+
+The following TLS repair is on main and is not included in Server 20260903.
+With that repair, 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
+[Go 1.27 TLS and OIDC discovery guide](https://silo.pgsty.com/blog/design/go127-tls-oidc-discovery/).
+
+## Documentation ownership
+
+User documentation is maintained at [silo.pgsty.com](https://silo.pgsty.com/docs/),
+with source in [pgsty/silo.pgsty.com](https://github.com/pgsty/silo.pgsty.com).
+The remaining `docs/` tree contains inherited references, examples, and tooling
+fixtures. Investigation logs, AI work records, and temporary reports are kept
+outside this repository; reusable findings belong in the companion site.
+See [AGENTS.md](AGENTS.md) for repository ownership and maintenance rules.

 ## Background

-This project was created in response to changes in the upstream community distribution and maintenance model. The maintainer’s analysis, alternatives considered, and early maintenance record are documented below:
+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:

-## License and Trademark
+- **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.

-## 维护政策
-
-活跃版本线的维护范围包括：
-
- 构建与依赖项维护；
- 适用的安全修复与公告；
- 针对可复现缺陷的范围明确的修复；
- 带版本的二进制、软件包、校验和与多架构镜像；
- Web Console、客户端、文档与 Pigsty 集成。
-
-改动保持克制，并在可行时提供测试。所有维护均为尽力而为，不承诺固定的响应、修复或发布时间。
-
-### 范围之外
-
- 独立产品路线图、新存储引擎或假设性的 S3 新特性；
- 大规模重写或显著扩大下游差异的改动；
- 历史版本或多条支持分支；
- 商业支持、SLA、7×24 服务或 SUBNET 服务；
- 部署设计、访问控制、监控、备份与恢复。
-
-## 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。
-
-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。
-
-## 下载与发行产物
-
-请先在[下载与安装](https://silo.pgsty.com/zh/download/)页面选择合适的安装方式；GitHub Releases 仍是带版本服务端二进制、校验和与源码归档的获取位置。

 ## 背景

-本项目源于上游社区发行与维护模式的变化。维护者对相关变化的分析、替代方案评估与早期维护记录见以下文章：
+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。

 # 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).

 ## 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.

 ## 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).

+- `contributors-light.svg` / `contributors-dark.svg`: human issue and PR authors across the SILO project scope, plus reviewed acknowledgements. Bots are excluded. Gold rings follow the reviewed companion-site roster; new authors are collected automatically.
+- `star-history-light.svg` / `star-history-dark.svg`: initial history reconstructed from the then-current stargazers; later points are daily observed totals, including decreases. Missing days are not fabricated.
+- `curated.json`: a cache of reviewed contributor credit from `pgsty/silo.pgsty.com/data/home/contributors.yaml`. The approved initial preview may be newer than the published site; a newer reviewed snapshot is retained until the site catches up.
+- `contributors.json`: generated contributor data and embedded raster avatars. Failed avatar refreshes use the previous image, or an initial when no image is available.
+- `history.json`: persistent daily totals. Keep this file when regenerating images.
+
+The SVGs are self-contained. Source and instructions live on the default branch;
+this branch contains generated assets only. Do not merge it into `main`.
