chore(gateway): merge main into integration

Sync main 84e24e767 into gateway/integration. Ports main-side additions to
the integration boundaries: the tier deletion diagnostics admin handlers move
to the owned admin request/response types, and the new lifecycle rule checks
in ecstore use the persisted lifecycle types instead of s3s DTOs. Keeps the
gateway git source in deny.toml while dropping the smithy-rs pin main retired,
and refreshes the test-count baseline for the merged tree.

 Risk and review shape:
 
-- **Exempt:** documentation, comments, formatting, or typos with no runtime, build, test, or agent-execution effect.
-- **Mechanical:** changes shown to preserve behavior, such as a symbol rename with unchanged callers or a file move with equivalent wiring. Run correctness and simplicity lenses. Classify tests, tooling, CI, and agent instructions by the behavior and authority they change, not their file type; deleting regression protection or changing failure propagation, publishing, or destructive actions can be high risk.
-- **Standard:** localized behavior changes. Run one integrated final-diff pass covering correctness, simplicity, and test coverage; add only domain lenses matched by the diff.
-- **High risk / substantial PR review:** high risk includes locking, erasure/quorum/heal, replication, multipart, RPC, lifecycle/tiering, persistence/fsync, IAM/KMS/auth, cryptography, on-disk/on-wire formats, and S3-visible semantics. Cover the applicable lenses from two perspectives: first trace the intended contract and implementation, then independently challenge its assumptions, failure paths, and evidence. Use separate reviewers when delegation is authorized and useful, or fresh sequential passes otherwise. Choose staffing and split lenses to fit the risk; a fixed reviewer count or duplicated review is not the goal.
-- **Outbound client defaults:** what `TargetClient`, `PutObjectOptions`, or 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
 
-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.

+are repository-relative. Read only the relevant sections during read-only review.
 
 ## Worktree and Disk Hygiene
 
-- 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.
-- 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 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.

-## 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 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.
+- 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.
 
 ## Rust Boundaries
 
-- 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.
+- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees.
 - 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/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.
+Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case`
+functions/variables, and `PascalCase` types. Do not rename unrelated existing
+violations.

 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.

-- Merge only with existing user authorization and satisfied applicable reviewer, check, and branch-protection requirements. Reviewer approval does not grant merge authority; user authorization does not bypass repository protections.
-- 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.

Confirmation binds the target, preview tag, and hash; a changed value or repeated/failed acceptance cycle invalidates it. Revalidate and obtain fresh confirmation before continuing.
 
 ## 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.

 ## Phase 4 — Run the artifact locally, verify the console
 
-Use a unique task-owned scratch directory. Select the versioned archive matching the host OS, architecture, and runtime, download its checksum file, and verify the archive before extraction. Do not substitute a different build when a matching artifact is unavailable; report that acceptance gap. The shell example below assumes the verified executable is at `RUSTFS_BINARY` (`rustfs.exe` on Windows), `SCRATCH` is the task directory, and `S3_PORT` and `CONSOLE_PORT` are distinct available ports. Use equivalent native commands when the shell differs.
-
-Bind both listeners to loopback. Choose task-only credentials, set loopback proxy exclusions for the server/client processes, and record the server PID. A port probe does not reserve a port; retry startup with fresh ports on a bind conflict rather than connecting to an existing service.

Set `RC_BIN` to that executable and record its version/digest. Avoid changing the user's installed client for this check.
-- Inspect the client's current help for an isolated configuration option and use it when supported. Otherwise choose a unique `PREVIEW_ALIAS` and confirm it is absent before creating it; never overwrite an existing alias. Use task-owned bucket/user names and input/output files.

 - Confirm the preview tag resolves to the Phase 2 CI-validated `PREVIEW_HASH`. If the release branch advances during acceptance, repeat Phases 2–5 with a new preview tag.

For a repository with no previous deliverable, verify a Full Changelog link exists and record the GitHub baseline fallback.
 - Confirm Helm is skipped. If preview Docker images are published, confirm they use only exact preview tags (and variant suffixes), with no `latest`, `alpha`, `beta`, or `rc` channel updates. Preview validation covers the built RustFS binaries, embedded console, and rc compatibility; it does not authorize advancing any installation default.

 ## CI Alignment
 
-When changing CI-sensitive behavior, keep local validation aligned with `.github/workflows/ci.yml`. Read the workflow file directly for the current gate steps — do not rely on (or add) a copied command list here; copies go stale. `make pre-pr` covers the shared local gates, not the full CI feature, platform, or end-to-end matrix. Select checks using the root verification tiers.

 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.

The actual functional and performance suites remain on their lab runners. Functional-chain health collection stays on the operator-managed `smoke-testing` runner as part of the automation environment.

 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.

-## 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.
+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.
 
 ## 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, 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.
-- 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.
-- 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 and Rust style 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.
-- For tool setup or instruction-loading problems, use [agent setup and validation](docs/testing/agent-instructions.md).

-Select checks from the final task-owned diff. Scoped `AGENTS.md` files may add a concrete path-specific check, but must not replace this tiering with a generic full-workspace gate.

+For prose, comments, agent instructions, and skill metadata that cannot affect
+runtime/build output:
 
 - Run `git diff --check`.
-- Run `scripts/check_doc_paths.sh` and `scripts/check_no_planning_docs.sh` for repository documentation/instruction changes, plus any affected skill validator. For changed execution rules, exercise representative task scenarios as described in [agent setup and validation](docs/testing/agent-instructions.md#changing-instructions).

+- Run the relevant documentation guard or skill validator when applicable.
+- Skip Cargo formatting, compilation, Clippy, tests, `make pre-commit`, and
+  `make pre-pr`.
 
 ### 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.
-- When changing a guard, test both a valid case and a case the old guard wrongly accepted or rejected. Wire its regression test into the existing applicable test runner.
-
 ### Localized Behavior Changes
 
 - Run `cargo fmt --all --check` for Rust changes.
 - Run the narrowest test that exercises the changed behavior.
-- Confirm the selected tests actually ran; a successful command with zero matching tests is not behavioral evidence.
-- For an explicitly requested coverage assessment, use the [coverage guide](docs/testing/README.md#coverage); a regression test alone does not require coverage measurement.
-- Run package-scoped Clippy for Rust behavior changes with the affected targets and features and `-- -D warnings`; successful compilation or tests do not replace lint checks.
-- Add package-scoped `cargo check` only for affected targets or features not compiled by those tests or lint checks. Select supported feature combinations from the affected package and CI configuration instead of assuming `--all-features` is appropriate.
-- Use `make pre-commit` only when its repository-wide fast checks add confidence beyond the focused checks.
+- For an explicitly requested coverage assessment, use the
+  [coverage guide](docs/testing/README.md#coverage); a regression test alone does
+  not require coverage measurement.
+- Add package-scoped `cargo check` or Clippy only for targets, features, public
+  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
+  beyond the focused checks.
 
 ### Broad Cross-Module Changes

 ## Adversarial Validation
 
-Adversarial validation applies to final implementation diffs, explicitly requested adversarial/design reviews, and agent-instruction changes that alter execution. Ordinary questions, diagnoses, status reports, non-adversarial code reviews, and low-risk planning do not trigger it.

 This guide covers the local development environment and the checks expected before contributing.
 
-### Shared Code Standards
-
-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.
-
-For assisted work, use only repository-maintained skills under `.agents/skills/`; external skills are not part of this project's workflow. Follow the root instructions and ordinary tools when no repository skill matches.
-
-For client setup and evidence that root/scoped rules are actually loaded, see [agent setup and instruction validation](docs/testing/agent-instructions.md). Keep project policy in shared sources rather than copying it into client-specific files.
-
 ### 🔧 Code Formatting Rules
 
-Use the repository formatter and lint configuration for changed code. Follow `rust-toolchain.toml`; if local and CI results differ, compare compiler, formatter, and Clippy versions as described in the [shared style contract](.agents/references/implementation.md#shared-style-contract).
+**MANDATORY**: All code must be properly formatted before committing. This project enforces strict formatting standards to maintain code consistency and readability.
 
 #### Verification Requirements
 
-Before submitting changes for review, complete the applicable [verification tier](AGENTS.md#verification) for the final diff. Documentation-only changes use documentation checks; they do not require Cargo formatting, compilation, Clippy, or tests.
+Before submitting your changes for review, you **MUST**:
 
-- For Rust changes, format with the repository configuration and verify with `cargo fmt --all --check`. Inspect formatter edits and keep unrelated work out of the change.
-- For Rust behavior changes, run focused behavioral tests and package-scoped Clippy with the affected targets/features and `-- -D warnings`. Compilation alone does not check lint policy, and a test filter matching zero tests does not verify behavior.
-- Add compilation checks only for affected targets/features not already compiled by those checks. Use supported feature combinations; do not default every contribution to `--all-features` or full-workspace checks.
-- Complete applicable CI gates before merge. Local scope selection does not waive CI requirements or permit weakening a gate.
+1. **Format your code**:
+
+   ```bash
+   cargo fmt --all
+   ```
+
+2. **Verify formatting**:
+
+   ```bash
+   cargo fmt --all --check
+   ```
+
+3. **Pass clippy checks**:
+
+   ```bash
+   cargo clippy --all-targets --all-features -- -D warnings
+   ```
+
+4. **Ensure compilation**:
+
+   ```bash
+   cargo check --all-targets

-`make pre-pr` is the broader local gate: formatting, shared and additional repository guards, `clippy-check`, and `test` (script tests, workspace tests excluding `e2e_test`, and doc tests).

 ## Error Type Design
 
-- 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.
+- 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.
 - 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.
 - When resetting multi-field atomic statistics, use a version/sequence counter or accept that concurrent readers may see partial snapshots; document the tradeoff.
 - `std::sync::Mutex` is acceptable in async context only when held for a brief, non-`await`-containing critical section. If in doubt, use `tokio::sync::Mutex`.

 ## Type Casting
 
-- Never use `as` for numeric conversions that may truncate or overflow. Use `try_into()` with typed error handling; clamp or saturate only when the domain explicitly requires it.
-- Before converting floating-point input to an integer, validate finiteness, sign, and the destination range. A lower-bound clamp alone is insufficient.
-- Review narrowing, signedness-changing, and float-to-integer casts against the value range and domain contract; do not require unrelated rewrites of proven lossless conversions.

+- Before converting floating-point input to an integer, validate finiteness,
+  sign, and the destination range. A lower-bound clamp alone is insufficient.
+- Treat every `as` cast in a PR review as a potential bug; require justification.
 
 ## Testing
 
 - Keep unit tests close to the module they test.
 - Keep integration tests under each crate's `tests/` directory.
-- Add or update regression tests when existing tests do not directly cover the changed behavior; a bug regression should fail without the fix.
-- Every test needs an observable failure criterion. Direct assertions, delegated assertions, snapshots/properties, `#[should_panic]`, and meaningful `Result` failures are all valid; a call that can silently succeed is not.

 - In tests, prefer `.expect("context: what was being tested")` over bare `.unwrap()`. A test failure should tell you which operation failed and with what input.

-### Scanner mixed-version gate
-
-The Linux N/O scanner gate needs a separately qualified `33482bb` server, which supports scoped ACKs. Set `RUSTFS_SCANNER_COMPAT_OLD_BINARY` to that executable and `RUSTFS_SCANNER_COMPAT_OLD_SHA256` to its independently verified digest. The release binary used by ordinary upgrade CI is a different baseline. Missing or mismatched inputs fail the test.
-
-Enable the harness-only `scanner-peer-mixed-version` feature explicitly; keep the server wrapper features identical between build and run:
-
-```bash
-python3 scripts/e2e_binary.py build --features e2e-test-hooks
-python3 scripts/e2e_binary.py run --features e2e-test-hooks -- \
-  cargo nextest run --profile e2e-distributed -p e2e_test \
-  --features scanner-peer-mixed-version --ignore-default-filter \
-  -E 'test(=distributed::scanner_peer_bucket_test::scanner_peer_bucket_new_coordinator_certifies_old_peers_and_scopes_next_cycle)' \
-  --test-threads 1 --retries 0 --no-tests=fail
-```
-
-The separate `scanner_peer_bucket_new_coordinator_certifies_old_worker_peers_and_scopes_next_cycle` case uses the same feature and qualified old binary inputs. Select its exact name in the command above. It keeps the original N process enabled and starts the three official O replacements with `RUSTFS_SCANNER_ENABLED=false`: their autonomous scanner loops are disabled, while real S3 dirty tracking, authenticated snapshots, publication leases, scoped ACKs, and N-dispatched RemoteScanner workers remain active. It records each node's actual scanner status and retains the same identity, durability, root, ACK, data-conservation, and physical-walk requirements. This fixed-role case does not validate autonomous O scanning or all-enabled election behavior. The original all-enabled N/O test remains separate and has not passed acceptance; a fixed-role result cannot satisfy that gate.
-
-For this fixed-role case, the `e2e-test-hooks` server also records the N client's complete bounded worker inventory. Requests are observed before opening the normal stream and paired only after authenticated source/plan validation and terminal EOF. Closed manifests and final health receipts must bind both cycles to their actual candidate/root; the next cycle needs exactly four sets of hot-only execution and at least one positive-progress worker mapped to a measured official O process. A zero-progress Current response, missing/extra request, unhealthy recorder, or missing physical coverage fails the gate. The recorder does not add O hooks or change any protocol or timeout. Final health reads check immutable closed-cycle evidence, not current N liveness.

+//! Dual-stack differential: one `rustfs` binary, two processes, one SDK script (rustfs/backlog#2740).
+//!
+//! Stack A always runs `RUSTFS_S3_STACK=legacy`. Stack B runs the value of `RUSTFS_E2E_STACK_B`
+//! (default `legacy` until the gateway stack is assembled), and `RUSTFS_E2E_STACK_B_REGION`, when
+//! set, starts B in another region so that a difference can be injected by hand. Both servers
+//! answer the script in `scenarios`, which covers every operation of `impl S3 for FS`; `compare`
+//! reports each `(op, field, a, b)` on which the answers differ, and every run writes its report
+//! to `<target>/dual-stack/<run>.json`. Two processes, not two embedded servers: bucket metadata
+//! is process-global, so two stacks in one process would read each other's buckets.

 - Keep network and disk operations async-friendly; avoid introducing unnecessary blocking.
 - Coalesce related `open`, `read`/`write`, `fsync`, and `close` filesystem steps into a single per-disk blocking closure rather than chaining multiple async or blocking dispatches, and route any closure that performs file or directory sync to the disk's dedicated fsync lane so stalled syncs cannot starve foreground metadata reads.
 - Pin a parent directory once (`openat2(BENEATH | NO_SYMLINKS)` on Linux) and reuse the pinned handle across sibling reads or same-directory renames instead of re-walking ancestor components per file.
-- For small metadata reads with a known size, pre-size buffers when it avoids repeated growth. Preserve the format's size limits, checked length conversions, and overflow handling; a filesystem size hint does not establish that an allocation is safe or that the file cannot change.
+- When the file size is already known from `fstat` metadata, pre-size the destination buffer (`len + 1`) before reading to EOF so small metadata reads complete in a single `read()` + EOF check rather than exponential-growth reallocations and syscalls.
 - Benchmark-sensitive changes should include measurable rationale.
 
 ## Allocation Discipline in Hot Paths
 
-- Before cloning in a loop or per-request path, consider the data copied and whether borrowing or moving ownership fits. Use `Arc` when shared ownership avoids meaningful copies and its lifetime and synchronization costs fit the operation.
-- Borrow temporary strings when lifetimes permit; choose `String` or `Cow<str>` when ownership or mixed borrowed/owned data requires it.
-- Preallocate collections when the size estimate is useful and bounded; do not reserve directly from unchecked input or speculative worst-case sizes.
+- Do not implement `Clone` on structs with >5 heap-allocated fields without considering `Arc` for heavy fields.
+- Before cloning a struct in a loop or per-request path, check if a reference or `Cow` would suffice.
+- When a struct contains a large buffer (e.g., erasure coding block), wrap it in `Arc` and pass by reference rather than cloning.
+- Use `&str` and `Cow<str>` instead of `String` for temporary computations (header parsing, signature building, path manipulation).
+- Use `HashMap::with_capacity()` / `Vec::with_capacity()` when the size is known or estimable.
 
 ## Lock Ordering
 
 - When a function acquires multiple locks, document the acquisition order in a comment.
 - Never acquire the same set of locks in different orders across code paths — this is a deadlock.
-- Use atomic `fetch_*` operations for unconditional counter updates and `compare_exchange` loops for conditional updates. A separate load followed by store must not lose concurrent updates.
+- Prefer `compare_exchange` loops over load-then-store for concurrent counters.
