chore(gateway): merge main into integration

Port main's changes into integration's relocated code: the XML compatibility
body bound and presigned-guard tests into legacy_compat, the policy-condition
fixes (#9150, #9159, #9163) into auth facts and the owned admin request API,
and record native publications on main's new fused delete-recovery paths.

 Risk and review shape:

-- **Mechanical:** renames, moves, test/tooling-only changes, and agent-rule
-  changes. Run correctness and simplicity lenses.

-  erasure/quorum/heal, replication, multipart, RPC, lifecycle/tiering,
-  persistence/fsync, IAM/KMS/auth, cryptography, on-disk/on-wire formats, and
-  S3-visible semantics. Cover all applicable lenses using exactly two
-  independent reviewers when delegation is explicitly authorized. Split the
-  lenses between them. Otherwise perform two fresh sequential passes.

-  the remote SDK configuration sends to every replication or migration target
-  is high risk for every target class even when the change fixes one. Follow
-  the SOP in `docs/postmortems/2026-09-03-replication-checksum-default-regression.md`:
-  run the outbound target matrix, document each new env knob in the same PR,
-  and list verified and unverified target classes in the PR Impact section.

 # Implementation Rules
 
-Applies when changing code or running artifact-heavy work. Paths below
-are repository-relative. Read only the relevant sections during read-only review.
+These implementation, style, and quality rules apply to all contributions, regardless of author or editor. Paths below are repository-relative. Read only the relevant sections during read-only review; select verification from the root `AGENTS.md`.
+
+## Shared Style Contract
+
+- Use the toolchain declared in `rust-toolchain.toml`, respect the minimum supported Rust version in `Cargo.toml`, and let `rustfmt.toml` and the configured Rust/Clippy lints define mechanical style. Do not override repository settings with personal formatter or lint preferences.
+- Follow the owning module's organization, imports, and domain terminology where repository rules leave a choice. Existing violations do not justify new ones; avoid unrelated cleanup in a focused change.
+- Rules using "must" or "do not" are requirements. Rules using "prefer" are defaults; depart when correctness, ownership, performance, or readability benefits justify it. Explain consequential tradeoffs, not every idiomatic choice. Where several approaches meet the contract equally well, the implementer chooses.
+- Follow the declared toolchain locally and the affected CI lane's toolchain for reproduction. The repository currently tracks `stable`; for a formatter/lint mismatch, compare `rustc -Vv`, `cargo fmt --version`, and `cargo clippy --version` with the failing run before changing code. Toolchain upgrades must keep local and CI settings aligned and pass their affected gates; do not silently raise `rust-version` or change lint policy to make a check pass.
 
 ## Worktree and Disk Hygiene
 
-- Start implementation from the latest `origin/main` and confirm the requested
-  change is not already present.
-- An existing clean, isolated task worktree is sufficient. Create another
-  worktree only when the current checkout is shared, dirty with unrelated work,
-  or belongs to another task.
+- For a new task, start from the latest `origin/main` unless a different base is requested, and confirm the requested change is not already present. When continuing existing work or a PR, preserve its branch, base, and task-owned changes; do not restart it from `main`.
+- An existing clean, isolated task worktree is sufficient. Create another worktree only when the current checkout is shared, dirty with unrelated work, or belongs to another task.
 - Never commit from a shared checkout.
-- Use a task-specific branch named `<type>/<topic>`, such as `fix/...`,
-  `feat/...`, `test/...`, or `docs/...`, unless the user specifies a name.
-- Do not include agent, tool, contributor, account, or organization names in
-  branch names.
-- Push to the user-requested remote or the repository's configured push remote.
-  Do not hard-code or infer a remote from an account name.
-- Check free space before artifact-heavy builds, tests, coverage, or downloads.
-  Re-check before a broad gate when space is tight.
-- Remove only task-owned temporary/build artifacts. Never delete another task's
-  worktree or uncommitted data.
-- At handoff, mention disk or cleanup details only when they affected execution
-  or artifacts/worktrees remain intentionally.
+- Use a task-specific branch named `<type>/<topic>`, such as `fix/...`, `feat/...`, `test/...`, or `docs/...`, unless the user specifies a name.
+- Do not include agent, tool, contributor, account, or organization names in branch names.
+- Push to the user-requested remote or the repository's configured push remote. Do not hard-code or infer a remote from an account name.
+- Check free space before artifact-heavy builds, tests, coverage, or downloads. Re-check before a broad gate when space is tight.
+- Before handoff, remove the Cargo target directories and temporary worktrees the task created unless they stay intentionally or hold unmerged work. Identify build output by Cargo's markers (`.rustc_info.json`, `CACHEDIR.TAG`), not by directory name: `target` is also a source directory here.
+- Remove only task-owned temporary/build artifacts. Never delete another task's worktree or uncommitted data.
+- At handoff, mention disk or cleanup details only when they affected execution or artifacts/worktrees remain intentionally.
+- For Docker verification, ensure the tested image contains the intended binary. `buildx build` without `--load` leaves the image in the build cache; use the Makefile's loaded image and rebuild without cache only when stale artifacts are evidenced.
 
 ## Change Style
 
-- Preserve existing control flow unless changing it is required for correctness.
-- Prefer a direct local edit over new files, wrappers, managers, or speculative
-  abstractions.
-- Add a helper only when it removes current duplication, names a real domain
-  boundary, or isolates a non-trivial invariant.
-- Remove an in-scope path superseded by the change. If compatibility requires it,
-  adapt at the boundary to one canonical core and use the repository's
-  `RUSTFS_COMPAT_TODO` policy.
-- Comments explain non-obvious invariants or reasons. Do not narrate code or
-  record change history.
+- Preserve unrelated control flow. Restructure touched code only when needed for the requested behavior or an explicitly requested refactor; style preferences alone do not justify changing execution order or cleanup behavior.
+- Prefer a direct local edit over new files, wrappers, managers, or speculative abstractions.
+- Add a helper only when it removes current duplication, names a real domain boundary, or isolates a non-trivial invariant. Keep helpers near the code they support when the module's organization permits it.
+- Remove an in-scope path superseded by the change. If compatibility requires it, adapt at the boundary to one canonical core and use the repository's `RUSTFS_COMPAT_TODO` policy.
+- Comments explain non-obvious invariants or reasons. Do not narrate code or record change history.
 - Mention unrelated problems when useful; do not fix them in a narrow task.
 
+## Rust Style
+
+These repository-owned rules incorporate selected ideas from the [OpenCode style guide](https://github.com/anomalyco/opencode/blob/dev/AGENTS.md#style-guide), adapted to RustFS. That link is background, not an additional rule source. Apply these defaults to new or changed code; correctness and domain invariants take priority.
+
+- Default to immutable `let` bindings; use `mut` for actual state changes. Prefer `if` or `match` expressions when branches compute a value instead of initializing a placeholder and reassigning it.
+- Use type inference for obvious local values. Add annotations when inference needs help or the numeric, collection, or error type matters to understanding the code. Keep explicit types in function signatures and public contracts.
+- Keep the main path readable with guard clauses, `let ... else`, and `?` when immediate propagation is correct. Preserve explicit handling for recovery, cleanup, aggregation, and quorum decisions; `if`/`else` expressions and exhaustive `match` remain idiomatic.
+- Prefer readable iterator chains for straightforward mapping and filtering. Keep loops when they make state changes, early exits, or async operations clearer. Do not add intermediate collections or clones just to use iterators.
+- Inline trivial single-use expressions only when a binding adds no meaning. Keep names that explain domain concepts, aid debugging, or make ownership and guard lifetimes clear. Do not change lock release or drop timing for style.
+- Keep pure parsing, validation, and option-building helpers synchronous unless an async interface contract requires otherwise. This does not make blocking I/O or CPU-heavy work safe to run on async executor threads; offload it when needed to keep those threads responsive.
+
 ## Reuse and Boundary Rules
 
-- Before adding helpers, constants, fixtures, or wrappers, search the touched
-  crate, the domain-owning crate, `crates/utils`, `crates/common`, and relevant
-  direct dependencies.
-- Reuse requires matching semantics: normalization, error types, deadlines,
-  durability, and compatibility must fit the call site. A narrowly named local
-  helper is better than forced reuse with different semantics.
-- Validate untrusted input at its trust boundary, then trust the validated type.
-  Values crossing disk, RPC, persistence, or version boundaries remain
-  untrusted at every consumer.
-- Re-check boundary values immediately before destructive actions such as
-  delete, overwrite, or quorum decisions.
-- Every new branch needs a concrete triggering input/state. For decoded or peer
-  data, corruption and mixed-version input are valid triggers.
-- Required values must return a typed error when absent or corrupt; do not use a
-  default that converts corruption into a plausible result.
-- Attach error context once where it is actionable. Do not erase typed errors
-  below aggregation or quorum layers.
+- Before adding helpers, constants, fixtures, or wrappers, search the touched code and domain owner; check `crates/utils`, `crates/common`, and direct dependencies when they could own the behavior. Stop once the relevant reuse boundary is clear.
+- Reuse requires matching semantics: normalization, error types, deadlines, durability, and compatibility must fit the call site. A narrowly named local helper is better than forced reuse with different semantics.
+- Validate untrusted input at the boundary that owns it, then pass validated types inward without repeating checks whose guarantees still hold. Deserializing into a Rust type alone does not establish domain validity. Values newly read from disk, RPC, persistence, or another version must be validated at that consuming boundary.
+- For destructive actions such as delete or overwrite and for quorum decisions, check the relevant identity, generation, and authority under the operation's existing synchronization or precondition contract. A separate unguarded recheck does not prevent a check/use race.
+- Every new control-flow branch needs a concrete triggering input/state. For decoded or peer data, corruption and mixed-version input are valid triggers.
+- Required values must return a typed error when absent or corrupt; do not use a default that converts corruption into a plausible result.
+- Attach error context once where it is actionable. Do not erase typed errors below aggregation or quorum layers.
 
 ## Rust Boundaries
 
-- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees.
+- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees. Stricter scoped prohibitions, including `crates/AGENTS.md`, still apply. Invalid client, disk, or peer data must return errors rather than trigger panics.
 - Public APIs do not return `Result<_, String>`. Library APIs use domain errors unless intentional erasure is part of the boundary contract; expose a stored inner error through `Error::source()`.
 - Numeric conversions must not silently truncate. Use fallible conversions for untrusted values; validate finiteness, sign, and range before float-to-integer conversion. Clamp/saturate only when required by the domain.
 - Do not add crate-root `#![allow(dead_code)]`.
 
 ## Naming
 
-Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case`
-functions/variables, and `PascalCase` types. Do not rename unrelated existing
-violations.
+Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case` functions/variables/modules, and `PascalCase` types/traits. Name domain concepts and include units where a value would otherwise be ambiguous; do not optimize for short names. Do not rename public, serialized, or persisted fields merely to match a local style preference, or rename unrelated existing violations.
+
+## API and Operational Contracts
+
+- For new or changed public APIs, document the caller-visible behavior and relevant `# Errors`, `# Panics`, and `# Safety` conditions. Include a useful example or link to one when usage is non-obvious; avoid boilerplate sections that say nothing. Follow the [Rust API documentation guidelines](https://rust-lang.github.io/api-guidelines/documentation.html) within the scope of the change.
+- For async or storage APIs, state cancellation, retry/idempotency, partial-completion, ownership, and durability guarantees when callers rely on them. Make failure cleanup and commit points explicit in code and tests; do not imply atomicity that the implementation does not provide.
+- For protocol, persisted-format, configuration, dependency, or operational changes, check affected consumers and supported versions. Update relevant docs/examples and describe compatibility, upgrade/rollback limits, and new configuration defaults when they change. New dependencies must solve a current need and fit the workspace's license, toolchain, and feature policy.
+- For hot-path or resource-management changes, check allocation/copying, blocking, unbounded work, and lock duration where affected. Support performance claims with an appropriate measurement or clearly label them as expectations; a benchmark is not required for unrelated changes.
+
+## Behavioral Tests
+
+- For behavior changes, add or update the narrowest test that calls the real implementation and asserts an observable result. Existing tests can provide coverage when they directly exercise the changed behavior; do not duplicate production logic as the test oracle.
+- Cover the changed contract's relevant failure and boundary cases, not only success. A bug regression should fail without the fix; do not broaden assertions or rely only on a successful call when the result or side effect is what matters.
+- Follow `docs/testing/README.md` for test layers, runners, isolation, synchronization, and flaky tests. Use controlled clocks or explicit synchronization for time/concurrency tests instead of fixed sleeps, and keep waits bounded.
+- Report the checks actually run and their outcomes, including skipped or blocked checks and the behavior they leave unverified. Do not describe focused local checks as full CI coverage.

 Before creating or updating a PR, reuse completed review and verification:
 
-- Verify the actual base (normally `origin/main`) and the complete task diff,
-  including file names and whitespace. Exclude secrets, logs, generated
-  artifacts, and unrelated edits. Retain an existing PR's base unless requested.
-- Confirm the final diff passed the root verification tier; fix task-owned

-  authority without expanding the task. Do not start another general review.
-- Keep the English Conventional Commit title at most 72 characters. Use the
-  template headings, actual checks, material risks, and rollback notes.
-- Immediately before writing to GitHub, confirm the head and task diff are
-  unchanged. Rerun only checks invalidated by edits or relevant state changes.

-  resume the requested monitor.
-- Never merge without required reviewer approval or explicit authority.
-- After an observed merge, verify the commit reached the base, then clean the
-  task worktree/branch when safe. Preserve unmerged work for closed PRs unless
-  deletion was explicitly authorized.

 ## Recovery
 
 - Before the final tag exists, land fixes on main, backport to the candidate, verify target versions, and restart branch CI/acceptance. Use a new preview iteration once a preview was tagged; main may advance independently.
+- If only an external build input changed, record it, create a new preview iteration even when the source SHA is unchanged, and repeat the affected build and artifact acceptance before fresh confirmation. Reuse source checks whose inputs remain valid.
 - Once the final tag exists, retry publication jobs for that exact tag. A source fix requires a newly confirmed target, not retagging or a newer preview. Phase 7 retries recheck artifact availability and superseding releases.
 - If abandoned after the bump merged, report the unpublished version on main and record whether to revert or let the next release overwrite it. Deleting unpublished candidate branches or preview tags requires an explicit decision. Completed release branches follow Phase 7 cleanup; keep release tags.

+- CI rebuilds from the same source with a different tag name, so the binary self-reports `<target>`. Other inputs can change: `build.yml` reads Console `releases/latest` during each build. Compare the actual Console tag, URL, and verified digest in every final build job with the accepted preview record, and inspect available build provenance for other relevant changes. A pre-tag check cannot prevent a later input change. On a mismatch or missing evidence, repeat affected acceptance against the final artifacts and report the limitation; failed acceptance leaves release validation incomplete even if publication already succeeded. Never move the final tag to conceal a failure.
 - Verify the final tag's complete publication path: all matrix and release jobs green; `gh release view "<target>"` shows the full versioned and `-latest` asset set plus checksums, SBOM, and provenance; Docker and Helm workflows succeed; `latest.json` points to `<target>`. A stable target must have `isPrerelease=false` and `isLatest=true`. An alpha/beta/rc target must have `isPrerelease=true`; GitHub does not permit prereleases to be Latest, but the project `latest.json` still advances to the final non-preview target.
 - Verify the final Release body contains `## What's Changed` and a Full Changelog link. When `PREVIOUS_DELIVERABLE` exists, the link MUST be `https://github.com/rustfs/rustfs/compare/<PREVIOUS_DELIVERABLE>...<target>` and the baseline MUST equal the preview Release baseline; for example, both `1.0.0-beta.12-preview.1` and `1.0.0-beta.12` compare from `1.0.0-beta.11`.

+Create the host directories and grant the container user write access before starting this example; official images run as UID/GID `10001:10001`. Set both credential variables to your own values, then run `docker compose config` to inspect the resolved configuration locally before `docker compose up -d`. The resolved output includes credentials, so do not share it publicly.
+
+With list syntax, use `- RUSTFS_OBS_LOG_DIRECTORY=/var/log/rustfs/` or quote the whole item as `- "RUSTFS_OBS_LOG_DIRECTORY=/var/log/rustfs/"`. Writing `- RUSTFS_OBS_LOG_DIRECTORY="/var/log/rustfs/"` passes the inner quotes literally, making this a relative path beginning with `"`, which can fail with `mkdir: cannot create directory '"': Permission denied`. This also applies to addresses and credentials: fix every affected list item, rather than only the log directory. The entrypoint preserves configured values, including literal quotes in valid paths and secrets.

@@ -27,11 +27,15 @@ A job runs on `ubuntu-latest` unless it has one of these reasons, and the reason
 
 1. **Disk.** It restores or produces the workspace `target/`: `cargo build` or `cargo test` with `--all-targets`, `cargo nextest run --all`, or any reader of the `ci-dev` / `ci-feat-*` caches. The workspace test build leaves about 64 GB in `target/`; a hosted runner has about 14 GB.
 2. **Critical-path CPU.** It is a build that several downstream lanes wait on and would blow its timeout at 4 vCPU (`build-rustfs-debug-binary` gates the e2e and s3-tests lanes).
-3. **Hardware.** Native aarch64, Docker-in-Docker, or the lab machines.
+3. **Hardware or environment.** Native aarch64 or access to the lab machines. Docker alone is not a reason: hosted Ubuntu ships Docker and supports the QEMU and Buildx setup actions.
 4. **Cache ownership.** It reads a `rust-cache` key that a self-hosted job writes (see the cache rule below).
 
 Jobs that do only the following have no reason to be self-hosted: shell or Python scripts, `cargo fmt`, `cargo deny`, typos, actionlint, API calls (`gh`, dependency review, issue and stale bots, CLA checks), downloading an artifact and running a prebuilt binary, or a `cargo build -p rustfs` with its own cache key. `e2e-distributed.yml` and `e2e-upgrade.yml` build the server and the `e2e_test` harness on `ubuntu-latest` inside their budgets, so "it compiles something" alone is not a reason.
 
+The functional chain's `prepare` and `complete-chain` jobs, the performance runner availability check, and runner hygiene use `ubuntu-latest`: they inspect APIs or artifacts, not the lab hosts. The actual functional and performance suites remain on their lab runners. Functional-chain health collection uses `ubuntu-latest` so a lab outage cannot also stop its independent monitor. Docker image packaging also uses `ubuntu-latest` for both musl and glibc variants; it downloads release binaries rather than compiling the workspace, and still sets up QEMU and Buildx explicitly.
+
+Moving these jobs off AKS reduces capacity demand, not necessarily the Azure bill immediately. VM costs fall only when nodes scale down or smaller capacity replaces them.
+
 A hosted runner is also the only choice for a few things the pods cannot do: `mount -o loop` and `mount -t tmpfs` fail inside the ARC pods, and a container runtime cannot guarantee that `io_uring_setup` is allowed. `uring-integration` and `e2e-distributed` are on `ubuntu-latest` for that reason, not for cost.

+Nested instructions add to ancestor rules; they do not discard non-conflicting rules. A skill cannot expand the user's requested scope or grant authorization.
+
+## Delivery Contract
+
+- Establish the requested outcome, affected boundaries, and observable acceptance criteria before editing. For substantial work, keep a short plan with verification points; a small local edit does not need a formal plan or new document.
+- Preserve correctness, security, durability, compatibility, and user-owned work. Within those boundaries, choose the reasoning process, algorithm, and tools; only real dependencies and explicit approval/acceptance gates constrain execution order.
+- Choose the simplest design that satisfies the actual contract. Explore alternatives or restructure in-scope code when evidence justifies it; minimum diff size is not a reason to keep a defective design. Avoid speculative features and unrelated cleanup.
+- Complete the authorized work, verify the final result, and report material limits honestly. Distinguish implemented, locally verified, CI-passed, published, and merged states; never substitute one for another.
 
 ## Operating Model
 
-- Inquiry, diagnosis, review, and planning tasks are read-only unless the user
-  explicitly requests changes.
-- Ordinary diff/commit reviews use the finding standard below directly; no
-  generic review skill is required. PR and high-risk reviews retain their workflows.
-- For implementation, read the relevant code, tests, and local guidance, then
-  make the smallest change that satisfies the request.
-- State assumptions only when they affect behavior or verification. Ask only
-  when a wrong assumption would materially change the result.
-- Do not load every skill or inspect unrelated modules preemptively. Select a
-  skill only when its description directly matches the request or changed
-  surface.
-- Resolve repository workflow skills under `.agents/skills/` when a global
-  skill has the same name, unless the user explicitly selects another path.
-- Avoid repeated reads and equivalent verification commands once enough
-  evidence exists.
-- Search for relevant symbols/headings before reading long files; return only
-  matching ranges. If output is truncated, narrow the query instead of repeating
-  a full read. Keep reusable raw logs in task artifacts and report the evidence.
-- Reuse authorization already given in the conversation. Resolve routine choices
-  within that scope and continue independent work while a material question is
-  pending. Before requesting missing approval, prepare the concrete result that
-  is already authorized; retain explicit merge and release gates.
-
-- Keep individual tool outputs concise. Save large outputs to task-owned logs
-  and retrieve only the relevant ranges.
+- Inquiry, diagnosis, review, and planning tasks are read-only unless the user explicitly requests changes.
+- Ordinary diff/commit reviews use the finding standard below directly; no generic review skill is required. PR and high-risk reviews retain their workflows.
+- For implementation, read the relevant code, callers, tests, and local guidance. Verify assumptions against the current checkout; comments, prior notes, and external examples can be stale.
+- State assumptions only when they affect behavior or verification. Ask only when a wrong assumption would materially change the result.
+- Do not load every skill or inspect unrelated modules preemptively. Select a skill only when its description directly matches the request or changed surface.
+- Use only repository-maintained skills under `.agents/skills/` in this checkout. Do not load, invoke, install, or fall back to skills from user directories, global installations, plugins, downloads, or other repositories, including through a local skill's references.
+- If no repository skill matches, use the repository instructions and ordinary tools. If an explicitly required repository skill is missing, report the missing file; do not substitute an external skill or silently claim the workflow completed.

+- Keep individual tool outputs concise. Save large outputs to task-owned logs and retrieve only the relevant ranges.
+- Parallelize independent searches and checks when they do not contend for shared state or resources. Delegate bounded independent work when authorized; assign file ownership for edits and integrate the results. Keep dependent mutations sequential.
+- Keep each Markdown prose paragraph and each prose list item on one source line; use editor soft wrapping. Preserve intentional structure, code-block line breaks, indentation, and language tags.

 ## Task-Specific Guidance
 
 Read only the reference needed for the current task, once per unchanged context:
 
-- Before code changes or artifact-heavy work, read [implementation rules](.agents/references/implementation.md).
-  For a read-only code review, use its change-style and boundary sections as needed.
-- Before commits, pushes, PR creation/updates, or posting to PRs/issues/discussions,
-  read [Git and PR rules](.agents/references/pull-requests.md).
-  Reuse existing authorization; a reference does not authorize posting, merging, or publishing.

 ### Non-Behavioral Source Changes
 
 - Run the formatter/validator for the changed language.
 - Add compilation or doctests only when syntax or executable examples changed.
 
+### Tooling, Build, and CI Changes
+
+- Run the changed language's validator and the narrowest test of the actual entry point, including failure behavior. For workflow edits, follow `.github/AGENTS.md`; a documentation-only tier does not cover executable scripts or build settings.

 - Run `cargo fmt --all --check` for Rust changes.
 - Run the narrowest test that exercises the changed behavior.
-- For an explicitly requested coverage assessment, use the
-  [coverage guide](docs/testing/README.md#coverage); a regression test alone does
-  not require coverage measurement.

-  APIs, error handling, or control flow not compiled by the focused test.
-- Use `make pre-commit` only when its repository-wide fast checks add confidence

+### Deployment
+
+- Existing volumes created by older root-running container images must be writable by the non-root runtime identity before upgrading. The default container UID/GID is `10001:10001`; stop the affected instances, verify host mount paths, and for ordinary bind mounts run `sudo chown -R 10001:10001 /actual/data /actual/logs` on each RustFS data/log mount. Account for ACLs, NFS, Kubernetes, and rootless UID mappings. Image-build ownership changes do not migrate mounted data. See the Docker Quick Start in [README.md](README.md).
+- Local disk initialization now checks file creation, writing, and deletion in the data root and fixed internal metadata directories. Unwritable disks are rejected using existing startup/quorum rules, with filesystem errors and Unix runtime/owner IDs logged for permission failures, instead of admitting those disks and discovering the mismatch on a later write. Existing object trees are not scanned and volume ownership is never changed automatically.

 - **Header-signed SigV4 requests honour only signed headers** (GHSA-xm99-m3gq-83g8): a request authenticated with a SigV4 `Authorization` header that carries an `x-amz-*` request header not listed in its `SignedHeaders` is now rejected with `403 AccessDenied` ("There were headers present in the request which were not signed"), matching AWS S3 and the presigned rule from GHSA-g8w9-qw9q-fghr. Previously anyone holding one header-signed `PutObject` request could add an unsigned `x-amz-copy-source` and turn it into a `CopyObject` that ran with the signer's permissions, copying any object the signer could read into the target. An `Authorization` header whose algorithm token is not `AWS4-HMAC-SHA256` is now rejected instead of being verified as SigV4. The request-envelope headers `x-amz-content-sha256`, `x-amz-decoded-content-length`, `x-amz-trailer` and `x-amz-checksum-algorithm` (the same set the upstream `s3s` fix exempts) and `x-amz-cf-id` (CloudFront) remain tolerated unsigned; AWS SDKs and RustFS's own signers already sign every other `x-amz-*` header.

+- The persisted replication MRF journal is now replayed every 5 minutes while the server runs, not only at startup. Delete-marker purges whose targets were unreachable, and replications that overflowed the worker queues, now converge within one replay interval after the target returns instead of waiting for a restart. A target that stays down is re-attempted once per retained entry per interval across the cluster: the start time of the last pass is shared through a small `config/replication/mrf.bin.replay` object, so nodes do not each replay once per interval. Older versions ignore that object; existing persisted formats are unchanged.
 - Upgrade and rollback: upgrade every node in one site consecutively and verify reconciliation before moving to the next site; do not intentionally run a site mixed-version. Target-version ledger keys are harmless on rollback, although old code cannot use their routing. Before rolling back past [#7307](https://github.com/rustfs/rustfs/pull/7307), drain or repair every pending version purge: older code can free a retained version's data directory before its remote purge is acknowledged.

+All contributions, whether written by a person or generated with assistance, follow the same [implementation and Rust style rules](.agents/references/implementation.md), root [quality and verification policy](AGENTS.md), and applicable scoped `AGENTS.md` files. Repository formatter/lint settings and domain contracts take precedence over personal preferences. Keep style-rule changes in those shared sources rather than maintaining a second version here.

 - **Never bypass formatting checks** - they are there for a reason
-- **All CI/CD pipelines** will also enforce these same checks
-- **Pull requests** will be automatically rejected if formatting checks fail
+- **CI workflows** define the checks for each event and changed surface; see [CI gates](docs/testing/ci-gates.md)
+- **Required checks** must pass before merge; resolve formatting, lint, and test failures instead of bypassing them
 - **Consistent formatting** improves code readability and reduces merge conflicts

-## 📝 Pull Request Guidelines
+## Pull Requests
 
-### Language Requirements
-
-**All Pull Request titles and descriptions MUST be written in English.**
-
-This ensures:
-- Consistency across all contributions
-- Accessibility for international contributors
-- Better integration with automated tools and CI/CD systems
-- Clear communication in a globally understood language
-
-#### PR Description Requirements
-
-When creating a Pull Request, ensure:
-
-1. **Title**: Use English and follow Conventional Commits format (e.g., `fix: improve s3-tests readiness detection`)
-2. **Description**: Write in English, following the PR template format
-3. **Code Comments**: Must be in English (as per coding standards)
-4. **Commit Messages**: Must be in English (as per commit guidelines)
-
-#### PR Template
-
-Always use the PR template (`.github/pull_request_template.md`) and fill in all sections:
-- Type of Change
-- Related Issues
-- Summary of Changes
-- Checklist
-- Impact
-- Additional Notes
-
-**Note**: While you may communicate with reviewers in Chinese during discussions, the PR itself (title, description, and all formal documentation) must be in English.
-
----
-
-Following these guidelines ensures high code quality and smooth collaboration across the RustFS project! 🚀
+Follow the [Git and PR rules](.agents/references/pull-requests.md) and current [PR template](.github/pull_request_template.md). Use English Conventional Commit titles, describe the changed behavior, and provide actual verification evidence and material limits. Keep template headings in the template itself rather than maintaining a copied list here.

 The RustFS container runs as a non-root user `rustfs` (UID/GID `10001:10001`). If you bind-mount host directories with Docker or Compose, every mounted path must be writable by that user, otherwise startup may fail with permission denied errors. This applies to data directories, log directories, and TLS certificate directories when `RUSTFS_TLS_PATH` is enabled.
 
+**Upgrading an existing data volume:** some older images ran as root. Replacing the image does not change ownership of mounted files. Before upgrading to a non-root image, stop the instances using the volume, confirm the actual host mount paths and runtime UID/GID, and grant that identity access to all existing data and log directories. For ordinary Docker bind mounts using the default identity, run `sudo chown -R 10001:10001 /actual/data /actual/logs` on the host. Repeat for each data mount; do not apply this recursively to unrelated shared directories. Kubernetes, NFS, ACLs, and rootless UID mappings may require a different ownership or access-control adjustment.
+
+RustFS checks creation, writing, and deletion of a small temporary file in each data root and fixed internal metadata directories when opening a local disk. A failed check rejects that disk through the existing startup/quorum rules and logs the filesystem error; permission diagnostics include the runtime UID/GID and path owner on Unix. This is not a recursive scan of existing buckets or objects: permissions must also allow access to their contents. RustFS does not change ownership automatically. After migration, verify upload, download, and deletion rather than relying only on a green health endpoint.

+# RustFS image bootstrap
+
+The official image bundles this directory at `/etc/rustfs/bootstrap`. The default `buckets.json` is an empty JSON array, so the image starts RustFS directly and does not require a bootstrap endpoint or bootstrap credentials.
+
+To create buckets, replace `buckets.json` in a derived image with a JSON array of bucket names. The entrypoint creates each bucket if it does not exist and applies `public-access-block.json`, whose default blocks all four public access paths. Edit that file in the derived image only when public access is an explicit requirement.
+
+Optional per-bucket files use the bucket name as the filename without an extension:
+
+| Directory | File format | Applied operation |
+| --- | --- | --- |
+| `policies/` | S3 bucket policy JSON | `rc bucket anonymous set-json` |
+| `versioning/` | JSON boolean (`true` or `false`) | Enable or suspend bucket versioning |
+| `lifecycle/` | `rc bucket lifecycle rule import` JSON | Replace lifecycle rules |
+| `cors/` | JSON or XML accepted by `rc bucket cors set` | Replace CORS rules |
+| `notifications/` | JSON array of `{ "arn": "...", "events": ["..."] }` | Add or replace event rules by ARN (prefix/suffix filters are not currently accepted) |
+
+Every per-bucket file must correspond to a bucket listed in `buckets.json`. Applying these files is repeatable: bucket creation ignores existing buckets, while each configuration operation replaces or reconciles that bucket's requested state.
+
+When `buckets.json` is non-empty, set `RUSTFS_BOOTSTRAP_ENDPOINT` to the RustFS S3 endpoint reachable from the container, for example `http://rustfs:9000` for a Compose service or the internal service DNS name in Kubernetes. The entrypoint waits on that endpoint's `/health/ready`; it never assumes `localhost`. `RUSTFS_BOOTSTRAP_TIMEOUT` controls the readiness wait in seconds (default `120`, maximum `3600`). `RUSTFS_BOOTSTRAP_DIR` can point to a different in-image configuration directory; it defaults to `/etc/rustfs/bootstrap`. Set `RUSTFS_ACCESS_KEY` and `RUSTFS_SECRET_KEY`, or their `_FILE` variants, for bootstrap authentication. The endpoint and credentials are read at runtime and are not baked into the image.
+
+RustFS built-in IAM policies remain unchanged; the default bootstrap installs no custom bucket policies, lifecycle rules, versioning, CORS rules, or notification rules. The bundled RustFS CLI is resolved from a published release and its release checksum is verified. Set the Docker build argument `RC_RELEASE` to a version to pin it. Build the RustFS image after a CLI release containing the `bucket public-access-block` commands is available. For Kubernetes, the configured service must route traffic to the starting pod before its readiness probe succeeds (for example, with `publishNotReadyAddresses: true`); otherwise the service endpoint cannot reach the pod while the entrypoint waits for readiness.

 ## Error Type Design
 
-- Public API functions must return a typed error enum (preferably `thiserror`-derived), never `Result<_, String>`.
-- Do not use `Box<dyn Error>` or `Box<dyn Error + Send + Sync>` in public trait methods or struct methods. Define a concrete error type with specific variants.
-- When implementing `std::error::Error`, always override `fn source()` if you store an inner error. Breaking the error chain makes debugging impossible.
+- Fallible public APIs use typed errors that fit the boundary, preferably an existing domain error or standard error type; do not return `Result<_, String>`.
+- Preserve error variants callers need for recovery, aggregation, or quorum decisions. Use type-erased errors only when erasure is intentional in the boundary contract, not as a shortcut around error design.
+- When implementing `std::error::Error`, expose a stored inner error through `source()` so the error chain remains available.
 - Internal helpers that return `Result<_, String>` and are immediately wrapped via `.map_err(Error::other)` should return the actual error type directly.
 
 ## Concurrency
 
 - Document lock acquisition order when a module uses multiple locks. Never acquire the same set of locks in different orders across code paths.
 - Never hold a `tokio::sync::RwLock`/`Mutex` write guard across `.await` points unless the critical section is unavoidably async and the hold time is bounded.
-- Prefer direct atomic `fetch_*` operations for unconditional updates and
-  `compare_exchange` loops only for conditional updates such as peaks or
-  adaptive state.
+- Prefer direct atomic `fetch_*` operations for unconditional updates and `compare_exchange` loops only for conditional updates such as peaks or adaptive state.

Capacity requests return `ServiceUnavailable` until the scanner publishes a complete snapshot certified for the current bucket incarnation and authoritative quota metadata can be read. Legacy or mixed-version snapshots without an incarnation proof cannot serve capacity until a compatible scanner publishes a certified snapshot. Capacity also returns `ServiceUnavailable` when cluster or disk observations are missing, stale, or degraded. Retry after scanner convergence and storage or metadata recovery. Capacity assumes shard paths have independent backing space; shared physical storage can make the estimate optimistic. Set the flag to `false` to restore the normal object path, including deletion of a real object previously stored at that key.
