fix(ecstore): remove duplicate rename_data definitions from merge conflict

PR #7166 (refactor to isolate local object rename commit) extracted
rename_data_inner, rename_data_observed, and LocalRenamePreflightRejection
into disk/local/commit.rs. PR #7163 (drain control writes) was based on
code before the refactor and re-added the same definitions to local.rs,
causing 27 compilation errors (duplicate struct/method definitions and
unresolved helper symbols).

Remove the duplicate block (997 lines) from local.rs; the canonical
definitions in commit.rs are already imported via the module re-export.

Also fix 4 clippy warnings introduced by upstream:
- shared.rs: redundant guard pattern → direct pattern match
- tests.rs: needless struct update, needless borrow, cloned_ref_to_slice_refs

-
-Use when root `AGENTS.md` triggers adversarial validation or for a substantial PR
-review. Paths below are repository-relative. The root finding standard and
-completion rule apply; selecting a lens does not require finding a defect.
-
-Risk and review shape:
-
-- **Exempt:** documentation, comments, formatting, or typos with no runtime,
-  build, test, or agent-execution effect.
-- **Mechanical:** renames, moves, test/tooling-only changes, and agent-rule
-  changes. Run correctness and simplicity lenses.
-- **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 all applicable lenses using exactly two
-  independent reviewers when delegation is explicitly authorized. Split the
-  lenses between them. Otherwise perform two fresh sequential passes.
-- **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.
-
-Available domain lenses are security, concurrency/durability, compatibility,
-and performance. Select `.agents/skills/adversarial-validation/SKILL.md` for an
-explicit adversarial request, a high-risk change, or a substantial PR review;
-then read only its matching role references. A routine standard pass does not
-load the playbook unless the reviewer needs a RustFS-specific probe.

-# 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.
-
-## 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.
-- 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.
-
-## 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.
-- Mention unrelated problems when useful; do not fix them in a narrow task.
-
-## 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.
-
-## Naming
-
-Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case`
-functions/variables, and `PascalCase` types. Do not rename unrelated existing
-violations.

-# Git and Pull Request Rules
-
-Applies to commits, pushes, PRs, and issue/discussion actions. Paths below are
-repository-relative. User authorization and root `AGENTS.md` still govern scope.
-
-## Final PR Preflight
-
-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
-  failures and run missing scoped checks. Report unresolved required checks or
-  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.
-
-## Pull Request Lifecycle
-
-- Creating or updating a PR includes one immediate snapshot of checks,
-  mergeability, reviews, and unresolved threads.
-- Unless the user explicitly requests monitoring, a release workflow requires
-  it, or an automation already owns it, hand off after the PR is open with the
-  current state and next event to watch. Do not delay ordinary handoff with
-  fixed quiet-period sleeps.
-- For requested monitoring, use event-driven or bounded waits. Report only state
-  changes, actionable failures, or a meaningful prolonged delay.
-- Investigate failures/comments before changing code. Fix task-attributable
-  issues, rerun affected verification, push, reply or resolve the thread, then
-  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.
-
-## Git and PR Baseline
-
-- Follow Conventional Commits; keep the subject at most 72 characters.
-- Source comments, commits, PR titles, and PR bodies are in English.
-- Keep every heading from `.github/pull_request_template.md`; use `N/A` where
-  needed and include commands actually run.
-- Use `--body-file` for multiline `gh pr create`/`gh pr edit` content.
-- PR/issue/discussion content must not contain the literal sequence `\n` or
-  hard-wrapped prose paragraphs.
-- Do not include local absolute paths or tool-specific labels/prefixes in GitHub
-  content.
-- Resolve review threads after the underlying issue is fixed. If declining a
-  suggestion, reply with a short evidence-based reason.

-git fetch <repo-remote> <baseRefName> refs/pull/<N>/head
-git diff <baseRefOid>...<headRefOid> --stat
+git fetch origin pull/<N>/head:pr-<N>
+git diff main...pr-<N> --stat
 ```
 
-Resolve `<repo-remote>` to the PR repository; do not assume the current checkout's `origin` or `main` matches. Record the exact base/head used. If either moved during fetching, refresh the snapshot before reviewing. Classify using the repository review policy; instruction changes that affect agent execution are mechanical, not exempt.
+Classify the change by risk tier (per AGENTS.md):
+- **Exempt**: docs/comments/instruction-only, formatting, typos.
+- **Mechanical**: renames, file moves, test-only or tooling changes.
+- **Standard** (default): any behavior change.
+- **High risk**: locking, erasure coding, quorum/heal, replication, multipart, RPC, lifecycle/tiering, metadata formats, persistence/fsync, IAM/KMS/auth, on-disk/on-wire formats, S3 API-visible behavior.
 
-### 3. Review the changed behavior
+### 3. Cluster changed files and delegate review
 
-Group files by functional area to trace callers and invariants. Use the root risk tier's review shape and only matching lenses. File count does not authorize delegation. When delegation is explicitly authorized, high-risk/substantial reviews use exactly two independent reviewers with the applicable lenses split between them; otherwise use two fresh sequential passes. Reviewers do not spawn further agents.
+Group the changed files into logical clusters (by crate or functional area). For each cluster, spawn a subagent with a focused review prompt that includes:
+- The cluster's changed files and their diffs.
+- The applicable adversarial role probes (from the `adversarial-validation` skill).
+- The repository's AGENTS.md rules relevant to that domain.
 
-Findings need a concrete failure scenario with `file:line`; a null verdict briefly names the relevant probes. Reuse existing evidence and choose local checks from the final diff under the root verification policy.
+For standard-tier changes: correctness adversary + simplicity adversary + test-coverage skeptic, plus every role whose domain the diff touches.
+For high-risk changes: run all seven roles.
+
+Each subagent must produce findings (concrete failure scenario with file:line) or a null report ("attacked X, Y, Z — no break found").
 
 ### 4. Check CI status
 
 ```bash
-gh pr checks <N> --repo <owner/repo>
+gh pr checks <N>
 ```
 
-Investigate a failed check when it bears on a finding or the user requested CI diagnosis/merge readiness:
+If any checks fail, investigate:
 ```bash
-gh run view --repo <owner/repo> --log-failed --job=<JOB_ID>
+gh run view --log-failed --job=<JOB_ID>
 ```
 
-Use current evidence to distinguish pre-existing, flaky, and PR-caused failures. Do not classify them by guesswork or turn a code-only review into unrelated CI repair.
+Determine whether failures are pre-existing (on main), flaky, or caused by the PR.
 
 ### 5. Synthesize findings
 
-Report the PR, reviewed base/head, and risk tier, then summarize the assessment.
-Use the selected review's P0–P3 ratings and root finding standard: supported
-findings with `file:line`, failure scenario, and fix, or `No findings`.
-State the observed check status, including pending or unavailable checks, and
-the verdict (`APPROVE`, `REQUEST_CHANGES`, or `COMMENT`). Do not infer a pass
-from missing checks or add style nits to populate a clean review.
+Combine all subagent findings into a structured review:
+- **Summary**: one-paragraph overview of the change and overall assessment.
+- **Findings**: each finding with severity (critical/major/minor/nit), file:line, concrete failure scenario, and suggested fix.
+- **CI status**: pass/fail with notes on any failures.
+- **Verdict**: APPROVE, REQUEST_CHANGES, or COMMENT.
 
 ### 6. Post the review
 
-Only when posting is authorized, write the review body to a temp file and post via CLI. Refresh the PR head first; if it changed, review the delta and update the verdict before posting:
+Write the review body to a temp file and post via CLI:
 ```bash
 # Request changes
-gh pr review <N> --repo <owner/repo> --request-changes --body-file /tmp/pr_review.md
+gh pr review <N> --request-changes --body-file /tmp/pr_review.md
 
 # Approve
-gh pr review <N> --repo <owner/repo> --approve --body-file /tmp/pr_review.md
+gh pr review <N> --approve --body-file /tmp/pr_review.md
 
 # Comment only (no verdict)
-gh pr review <N> --repo <owner/repo> --comment --body-file /tmp/pr_review.md
+gh pr review <N> --comment --body-file /tmp/pr_review.md
 ```
 
-For authorized inline comments, use [the submission example](references/posting.md).
+For inline comments on specific lines, use the GitHub API:
+```bash
+cat > /tmp/pr_review.json <<'EOF'
+{
+  "body": "review body",
+  "event": "REQUEST_CHANGES",
+  "comments": [
+    {
+      "path": "crates/foo/src/bar.rs",
+      "line": 42,
+      "body": "finding description"
+    }
+  ]
+}
+EOF
+gh api --method POST /repos/{owner}/{repo}/pulls/<N>/reviews --input /tmp/pr_review.json
+```
 
 Always use `--body-file` or `--input`, never inline multiline `--body`.
 
 ### 7. Handle follow-up
 
-Follow the [PR lifecycle](../../references/pull-requests.md) and any explicit monitoring request. For follow-up, fetch the new head and compare the recorded reviewed SHA with the new SHA; revisit affected callers and findings. Never use an unfetched `origin/pull/<N>/head` ref as evidence. Update the posted review or resolve addressed threads only within existing authorization.
+If the review requests changes:
+- Monitor for new commits: `gh pr view <N> --json commits`
+- Re-review changed files only: `git diff pr-<N>..origin/pull/<N>/head`
+- Update the review when findings are addressed.
+
+If CI was failing due to pre-existing main breakage:
+- Comment on the PR noting the failure is pre-existing.
+- Suggest updating the branch: `gh pr update-branch <N>`
+
+## Output format

 ## Notes
 
 - The user may ask for review in Chinese; respond in the same language but keep the review body in English per AGENTS.md rules.
 - When the user asks for "多角色对抗 review", run the full adversarial validation protocol — this skill's step 3 covers that.
 - If the PR is from a fork, check `maintainerCanModify` before attempting to push fixes.
-- For very large PRs, batch the review by functional area while keeping the same bounded review shape.
+- For very large PRs (>50 files), cluster aggressively and delegate in parallel to keep review time reasonable.

+This skill orchestrates a full release. It wraps `rustfs-release-version-bump` (which only edits version files and opens the PR) with a mandatory preview-tag validation loop before the final tag is published.

-Preview and final tags must therefore share the validated source commit;
-their tag-dependent version and asset names differ. The channel and cleanup
-constraints are defined once under Preview tag naming and Hard rules below.
+Core design: **version files never carry a `-preview.N` suffix**. The preview suffix exists only in tag names. A preview tag creates a visible GitHub Release marked Prerelease and uploads versioned assets, but it never becomes GitHub Latest and never updates `*-latest`, `latest.json`, R2, Docker, or Helm channels. That Release is temporary: `build.yml` deletes it automatically once the final tag's Release is published, so the Releases page ends up carrying deliverables only while the `-preview.N` tags stay behind as the traceability record. This works because the binary self-reports the git tag it was built from (`build::TAG` via shadow_rs, see `rustfs/src/config/cli.rs` `SHORT_VERSION`), and `build.yml` derives artifact names and preview classification from the tag name — Cargo.toml's version is only a no-tag fallback. Therefore the preview tag and the final tag can (and MUST) point at the exact same commit: what you validated is byte-for-byte the source that ships.

 ### Console release gate

+Complete this gate before changing any RustFS version file or creating any RustFS tag. RustFS `build.yml` downloads the asset returned by `repos/rustfs/console/releases/latest`, so a successful Console build alone is insufficient.

+- Any diverged history or `behind_by > 0`: stop and resolve the Console release baseline explicitly. Do not guess a range or publish RustFS.
+
+2. Clone/fetch `rustfs/console` into a scratch directory and record its exact `main` commit. Before creating a tag, check for a `v*` tag or Release workflow already associated with that hash. If one is in progress, wait for it instead of creating another version:

+
+Console tags include the `v` prefix. Pushing the tag triggers `.github/workflows/release.yml` (`🚀 Release`). Remove `CONSOLE_SCRATCH` after the gate completes.

-Checks (all must pass):
-
-- `./rustfs --version` reports the preview tag name and the short SHA of `PREVIEW_HASH`. Reporting `<target>` without the `-preview.N` suffix means the build did not embed the tag — treat as FAIL and investigate before proceeding.
-- `curl -fsS http://localhost:9000/health/ready` returns ready.
-- Startup log shows the embedded console being served (this was the regression that `fix(release): require embedded console assets` guards).
-- Open `http://localhost:9001` in the browser: login with `rustfsadmin`/`rustfsadmin`; dashboard renders without JS console errors; create a bucket, upload a file, download it back (byte-identical), delete the object and bucket. Keep the server running for Phase 5.
-
-## Phase 5 — Validate with the latest rc client
-
-`rc` is the RustFS CLI client from <https://github.com/rustfs/cli>.
-
-- Ensure the latest release is installed: compare `rc --version` against `gh api repos/rustfs/cli/releases/latest --jq .tag_name`; update via `brew upgrade rustfs/tap/rc` (or download the release binary).
-- Point it at the preview server and run the command matrix, recording PASS/FAIL per command:
-
-```bash
-rc alias set preview http://localhost:9000 rustfsadmin rustfsadmin
-rc ls preview/
-rc mb preview/rel-check
-rc cp <local-file> preview/rel-check/
-rc stat preview/rel-check/<file>
-rc cat preview/rel-check/<file>          # matches source
-rc cp preview/rel-check/<file> ./out && cmp <local-file> ./out
-rc cp -r <local-dir>/ preview/rel-check/dir/
-rc find preview/rel-check --name "*"
-rc share download preview/rel-check/<file> --expire 1h   # presigned URL fetchable via curl
-rc rm preview/rel-check/<file> && rc rm -r --force preview/rel-check/dir
-rc rb preview/rel-check
-rc admin user list preview/
-rc admin user add preview/ relcheckuser relchecksecret12
-rc admin user remove preview/ relcheckuser
-rc alias remove preview

-
-- Any FAIL blocks the release. Afterwards stop the server and delete the scratch data directory.

+- No `#[serde(deny_unknown_fields)]` found across the entire codebase. Lesson: all structs deserialized from untrusted input (S3 API XML/JSON, lifecycle rules, bucket policies, replication configs) should have `#[serde(deny_unknown_fields)]` to reject malformed or adversarial payloads.
 - `#[serde(default)]` on security-critical fields silently accepts missing values as zero/empty. Lesson: when a field has security implications (retention days, permissions, limits), validate the deserialized value explicitly rather than relying on defaults.
-- Integer fields deserialized from user input and cast with `as` (e.g., `i32 as u32`) can wrap negative values to large positives. Lesson: validate ranges before casting; use `try_into()` with a typed error, or clamp only when the domain explicitly requires saturation.
+- Integer fields deserialized from user input and cast with `as` (e.g., `i32 as u32`) can wrap negative values to large positives. Lesson: validate ranges before casting; use `try_into()` or clamp.

 ## Usage assumptions
 - Focus scope is either changed lines/files, a module, or the whole repository.
-- Reuse a supplied coverage artifact when its revision, scope, and format match.
+- Coverage artifact must be generated or provided in a supported format.
 - If required context is missing, call out assumptions explicitly before proposing work.
 
 ## Workflow
 
 1. Define scope and baseline
-   - Derive the revision and scope from the request, diff, or supplied report.
-   - Default to the affected files/module; whole-workspace coverage requires that
-     scope in the request. Ask only if a wrong scope would change the result.
+   - Confirm target language, framework, and branch.
+   - Confirm whether the scope is changed files only or full-repo.
 
-2. Obtain coverage evidence
-   - First inspect a matching existing artifact; do not regenerate it merely
-     because this skill was selected.
-   - If measurement is needed, read the Coverage section of
-     [the testing guide](../../../docs/testing/README.md#coverage), check disk
-     space/tool availability, and select package/test-scoped `cargo llvm-cov`
-     using the repository's nextest configuration. `make coverage` measures the
-     whole workspace (excluding E2E) and is only for that requested scope.
-   - Collect only metrics the report supports. Missing branch/changed-line
-     coverage is unknown, not zero.
-   - If measurement cannot run, continue with code-based test proposals and
-     mark measured coverage unverified; do not invent a coverage percentage.
+2. Produce coverage snapshot
+   - Rust: `cargo llvm-cov` (or `cargo tarpaulin`) with existing repo config.
+   - JavaScript/TypeScript: `npm test -- --coverage` and read `coverage/coverage-final.json`.
+   - Python: `pytest --cov=<pkg> --cov-report=json` and read `coverage.json`.
+   - Collect total, per-file, and changed-line coverage.
 
 3. Rank highest-risk gaps
    - Prioritize changed code, branch coverage gaps, and low-confidence boundaries.
    - Apply the risk rubric in [coverage-prioritization.md](references/coverage-prioritization.md).
-   - Report up to 5–8 evidenced gaps; do not pad a small scope.
+   - Keep shortlist to 5–8 gaps.
    - For each gap, capture: file, lines, uncovered branches, and estimated risk score.
 
 4. Propose high-impact tests
-   - For each gap, name the behavior and regression, distinguishing assertions,
-     relevant normal/edge/failure cases, necessary setup, and estimated effort.
-   - Include only scenarios and setup that apply; reuse shared fixture details.
+   - For each shortlisted gap, output:
+     - Intent and expected behavior.
+     - Normal, edge, and failure scenarios.
+     - Assertions and side effects to verify.
+     - Setup needs (fixtures, mocks, integration dependencies).
+     - Estimated effort (`S/M/L`).
 
 5. Close with validation plan
    - State which gaps remain after proposals.
-   - Give a scoped verification command and behavior-based acceptance criterion;
-     use a coverage threshold only when the task or repository requires one.
+   - Provide concrete verification command and acceptance threshold.
    - List assumptions or blockers (environment, fixtures, flaky dependencies).
 
-## Report
+## Output template
 
-Summarize the supported metrics, then combine each ranked gap with its proposed
-test and validation. Include source lines only when supplied or inspected;
-mark missing metrics or locations as unknown. Do not duplicate gaps and tests
-in separate templates or fill empty categories for an otherwise small report.

 ## Summary of Changes
 <!--
-Describe the concrete problem and resulting behavior. For a behavior change, name the input or state that triggers it and the expected outcome. Explain any new dependency or abstraction that the change needs.
+Briefly explain what changed and why reviewers should accept it.
+Focus on behavior, compatibility, and review-relevant context.
 -->
 
 ## Verification
 <!--
-Give 1–3 concrete pieces of evidence for the changed behavior: the test or command, its observed result, and the regression it catches. For a bug fix, record a failing-before/passing-after check or explain why it was unavailable.
+List the commands or checks you ran, for example:
+- `make pre-commit`
 
-Identify the tested commit and any local changes. When testing a prebuilt binary or external service, include its source/version and artifact identity; a successful run against a different build is not evidence for this change.
-
-List relevant checks not run and the remaining risk. Use the validation tier in AGENTS.md; do not run broader checks solely to fill this section. For documentation-only changes, list the applicable documentation checks. Use N/A only when verification is not applicable.
+Use N/A only when verification is not applicable.

-# 4-node 4-disk distributed e2e lane.
-#
-# Each selected test starts a real localhost cluster via
-# `RustFSTestClusterEnvironment` (4 processes; 4 drives per node unless the
-# case is a two-site 4-node 1-drive pair or a 4-node upgrade). Membership is
-# `[profile.e2e-distributed]` in `.config/nextest.toml`. Storage-sensitive PRs,
-# nightly runs, and manual dispatches all execute the same fail-closed suite.
-# Upgrade cases download the same pinned previous release as e2e-upgrade.yml.
-#
-# Isolated pool filesystems: expand/decommission/rebalance cases require
-# independent `statfs` capacity. This job runs on GitHub-hosted
-# `ubuntu-latest` because the self-hosted `sm-standard-4` ARC pods cannot
-# create filesystems: `mount -o loop` fails with ENOENT (no
-# `/dev/loop-control`), and `mount -t tmpfs` fails with "cannot mount tmpfs
-# read-only" (no `CAP_SYS_ADMIN` in the initial namespace). The same reason
-# `uring-integration` and `e2e-s3tests.yml` left that label. The prepare
-# step mounts four 1 GiB tmpfs instances and exports `RUSTFS_E2E_POOL_ROOTS`.

-## Task-Specific Guidance
+## Worktree and Disk Hygiene
 
-Read only the reference needed for the current task, once per unchanged context:
+- 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.
+- 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.
 
-- 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.
-- Preserve unrelated work. Never commit from a shared checkout or delete another task's artifacts.
-- Source comments, commits, PR titles, and PR bodies are in English.
+## 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.
+- Mention unrelated problems when useful; do not fix them in a narrow task.
+
+## 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.

-For applicable work and substantial PR reviews, read the [risk tiers and review shape](.agents/references/adversarial-validation.md).
-Load only the matching domain probes; ordinary reviews do not become adversarial
-merely because this reference exists.
+Risk and review shape:
 
-A review has no finding quota; `No findings` is a complete outcome. A request to
-find problems is not evidence that a defect exists. Before reporting a candidate,
-check callers, invariants, and existing tests for evidence that disproves it.
-Findings need `file:line` and a concrete failure or violation of an explicit
-requirement. Missing required tests/checks are verification gaps, not proof of a
-runtime bug; name the unprotected behavior or unmet gate. Keep optional style or
-refactoring preferences out of defect findings unless that review was requested.
+- **Exempt:** documentation, comments, formatting, or typos with no runtime,
+  build, test, or agent-execution effect.
+- **Mechanical:** renames, moves, test/tooling-only changes, and agent-rule
+  changes. Run correctness and simplicity lenses.
+- **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 all applicable lenses using exactly two
+  independent reviewers when delegation is explicitly authorized. Split the
+  lenses between them. Otherwise perform two fresh sequential passes.
+- **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.
 
-Fix or rebut supported findings within the authorized scope. Once the required
-passes are complete, stop. Reopen only for changed code, new evidence, an
-unresolved finding, or an explicit re-review request; an unchanged diff does not
-need another pass at every conversation turn or workflow handoff.
+Available domain lenses are security, concurrency/durability, compatibility,
+and performance. Select `.agents/skills/adversarial-validation/SKILL.md` for an
+explicit adversarial request, a high-risk change, or a substantial PR review;
+then read only its matching role references. A routine standard pass does not
+load the playbook unless the reviewer needs a RustFS-specific probe.
+
+A finding must name a concrete input/state/interleaving and wrong outcome, or a
+specific missing regression check, with `file:line`. Resolve it by fixing the
+diff or rebutting it with code-path/test/invariant evidence. After a non-trivial
+fix, rerun only affected lenses.
 
 For high-risk PRs, record one concise verdict per covered lens in the PR body.
 
+## Pull Request Lifecycle
+
+- Creating or updating a PR includes one immediate snapshot of checks,
+  mergeability, reviews, and unresolved threads.
+- Unless the user explicitly requests monitoring, a release workflow requires
+  it, or an automation already owns it, hand off after the PR is open with the
+  current state and next event to watch. Do not delay ordinary handoff with
+  fixed quiet-period sleeps.
+- For requested monitoring, use event-driven or bounded waits. Report only state
+  changes, actionable failures, or a meaningful prolonged delay.
+- Investigate failures/comments before changing code. Fix task-attributable
+  issues, rerun affected verification, push, reply or resolve the thread, then
+  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.
+
+## Git and PR Baseline
+
+- Follow Conventional Commits; keep the subject at most 72 characters.
+- Source comments, commits, PR titles, and PR bodies are in English.
+- Keep every heading from `.github/pull_request_template.md`; use `N/A` where
+  needed and include commands actually run.

+- PR/issue/discussion content must not contain the literal sequence `\n` or
+  hard-wrapped prose paragraphs.
+- Do not include local absolute paths or tool-specific labels/prefixes in GitHub
+  content.

 ### Fixed
-- **Multipart admission queue**: an `UploadPart` waiting for a foreground write permit now waits at most 10 s by default (`RUSTFS_PUT_MULTIPART_FOREGROUND_ADMISSION_WAIT_TIMEOUT_MS`, previously 30 s), so a queued part returns S3 `SlowDown` before the client's socket write timeout drops the connection. Separately, the API listener no longer forces a 4 MiB `SO_RCVBUF` on every accepted socket (kernel autotuning applies; `RUSTFS_HTTP_SOCKET_RECV_BUFFER_BYTES` restores a fixed size), so a queued part no longer lets up to 8 MiB of unread body accumulate in kernel memory per connection, which is what throttled whole nodes under SDK-default multipart concurrency. Fixes #7385.
 - **Helm Ingress**: `customAnnotations` are now merged with class-specific annotations (nginx/traefik) instead of being ignored when `ingress.className` is set.
 - **Per-pool erasure parity**: Erasure parity (STANDARD and reduced-redundancy) is now resolved independently for every pool instead of reusing the first pool's value. A heterogeneous topology — for example a 4-drive pool plus a 2-drive pool created during expansion — previously inherited the first pool's parity and could resolve to zero data shards in the smaller pool, panicking Reed-Solomon construction on write. Automatic parity now resolves per pool (for example `2+2` in the 4-drive pool and `1+1` in the 2-drive pool). Fixes #4801.

   - Read paths: an object at or below `policy.inline_max_bytes` (16 MiB by default) is teed to the client and to the local store in a single source read; a larger object or a Range read streams through and a background pull stores the whole object. A HEAD miss is proxied to the source and stores nothing (`policy.head = local_only` disables it). Every source-backed response carries `x-rustfs-on-demand-migration: source`
   - Protections: a per-source circuit breaker, a per-key negative cache, singleflight per key, a concurrency limit and a bounded pull queue shared by the inline and background paths, an optional bandwidth limit, an anti-loop request marker, and the shared outbound-endpoint (SSRF) policy
   - Metrics under `rustfs_on_demand_migration_*` (`requests_total`, `pulled_bytes_total`, `pulled_objects_total`, `pull_failures_total`, `inflight_pulls`, `queue_depth`, `source_latency_seconds_*`, `breaker_state`), mirrored per node by the admin status route
-  - Listings: `ListObjects` v1 remains local with ordinary key markers. `ListObjectsV2` can merge source objects when `policy.list_through = true`; this is off by default
-  - Upgrade and rollback: finish upgrading every node before enabling ODM. An rc.5 node that writes bucket configuration drops the ODM fields from metadata; neither a later restart nor moving the service out of ECStore recovers them. Before rollback, disable ODM and securely retain the original full configuration and credentials. After every node returns to a compatible version, restore and validate that configuration. Redacted exports cannot replace the credential backup; source-only objects are unavailable through RustFS while ODM is disabled. See the upgrade and rollback section of `docs/operations/on-demand-migration.md`
-  - Optional Google dependencies: default and `full` server builds retain native GCS support. `cargo build -p rustfs --no-default-features --features ftps,webdav` excludes Google SDKs while preserving configuration decoding and redaction; native GCS ODM and tier operations require the `gcs` feature. Do not use that build with existing GCS-tiered data
-  - Limitations: PUT and DELETE never reach the source; a source object updated after it was pulled is not re-fetched; SSE-C source objects are unsupported and answer 424; `Last-Modified` on a pulled object is the local write time, with the source timestamp kept in metadata
+  - Limitations: listings show only local objects (the source is not merged into `ListObjectsV2`); PUT and DELETE never reach the source; a source object updated after it was pulled is not re-fetched; SSE-C source objects are unsupported and answer 424; `Last-Modified` on a pulled object is the local write time, with the source timestamp kept in metadata
 - **NATS JetStream Publish Path**: Opt-in at-least-once delivery for the NATS notify and audit targets. A NATS Core publish flushes to the connection without awaiting a broker acknowledgement, so an event can be lost across a broker restart or a reconnect after the send queue has already cleared it. A queued event now clears only after the JetStream `PublishAck`, so bucket notifications survive those interruptions. Off by default and byte-identical to the NATS Core path when disabled.
   - Three configuration keys per target: `JETSTREAM_ENABLE`, `JETSTREAM_STREAM_NAME`, and `JETSTREAM_ACK_TIMEOUT_SECS`, under the `RUSTFS_NOTIFY_NATS_` and `RUSTFS_AUDIT_NATS_` prefixes
   - Durable store-and-forward with a stable dedup id sent as the `Nats-Msg-Id` header, so a replay after a crash is collapsed by the server duplicate window

-The optional hook uses the checked-in `.pre-commit-config.yaml`. Install [pre-commit](https://pre-commit.com/#installation), then run this from the checkout or a linked worktree:
+Git hooks are **not** versioned in this repository, so a fresh clone has no

+choice is a one-liner that runs `make pre-commit`), you can mark it executable
+with:
 
 ```bash
 make setup-hooks

-The hook runs `cargo fmt --all --check` when staged files include Rust source. It does not compile the workspace or run tests. Fix formatting with `cargo fmt --all`, inspect and stage the result, then commit again.
+Or manually:
 
-`pre-commit install` resolves Git's hook directory for linked worktrees and preserves an existing hook in migration mode. If you use `core.hooksPath`, keep that hook manager and integrate `pre-commit run` there; the installer refuses to silently replace that configuration.

+chmod +x .git/hooks/pre-commit

-A local hook provides early formatting feedback. With or without it, follow the verification tiers in `AGENTS.md`, run relevant behavioral tests, and satisfy the CI merge gates. `make pre-commit` and `make dev-check` remain explicit broader commands.

 ## Quickstart
 
-> [!IMPORTANT]
-> **Pool expansion notice:**
->
-> - A single-node single-drive (SNSD) deployment is supported only as a standalone local path. It cannot expand in place or be added as a Pool. To move to a multi-drive topology, create a new deployment and migrate data through S3.
-> - Keep an existing multi-drive Pool's endpoints and Erasure Set width unchanged; expand by appending a new Pool. With ellipsis-based expansion, every Pool argument must contain an ellipsis expression and expand to at least two drive endpoints.
-> - Single-node multi-drive Pools and multi-node Pools with one drive per node are allowed, subject to valid Erasure Set geometry and EC settings; acceptance does not guarantee host-failure tolerance.
->
-> These topology rules follow MinIO, but automatic parity selection differs between the projects. See the [Pool layout compatibility and regression tests](docs/testing/pool-layout-compatibility.md) before expanding a deployment.

 ## 快速开始
 
-> [!IMPORTANT]
-> **Pool 扩容 Notice：**
->
-> - 单节点单盘（SNSD）部署仅支持使用本地路径独立运行，不支持原地扩容，也不能作为 Pool 加入集群。如需改为多盘拓扑，请创建新部署并通过 S3 迁移数据。
-> - 已有多盘 Pool 的端点和 Erasure Set 宽度应保持不变，扩容应追加新的 Pool。使用省略号表达式扩容时，每个 Pool 参数都必须包含省略号表达式，并展开为至少两个磁盘端点。
-> - 允许单节点多盘 Pool，也允许多节点、每节点一盘的 Pool，但必须满足 Erasure Set 布局和 EC 配置要求；配置合法不代表能够容忍整台主机故障。

-> 这些拓扑规则与 MinIO 一致，但两者的默认 parity 选择方式存在差异。扩容前请阅读 [Pool 布局兼容性与回归测试说明](docs/testing/pool-layout-compatibility.md)。

-- Before converting floating-point input to an integer, validate finiteness,

+- Never use `as` for numeric conversions that may truncate or overflow. Use `try_into()` with explicit error handling, or clamp with `value.max(0) as usize` when the domain is bounded.
+- `f64 as usize` saturates but is fragile; clamp to `[0, usize::MAX as f64]` first.

-## Foreground write admission environment variables
-
-Large direct `PutObject` requests and multipart `UploadPart` requests share one
-per-process permit pool that bounds how many bodies are ingested and written
-concurrently. Small direct PUTs stay on the legacy path.
-
-- `RUSTFS_PUT_LARGE_FOREGROUND_ADMISSION_ENABLE`
-  - enables the default-on pool; `false` keeps only the soft request counter.
-  - default is `true`.
-- `RUSTFS_PUT_LARGE_FOREGROUND_ADMISSION_LIMIT`
-  - permits in the pool; `0` derives half of `RUSTFS_OBJECT_MAX_CONCURRENT_DISK_READS`, clamped to `32`.
-  - default is `0` (32 permits at stock settings).
-- `RUSTFS_PUT_LARGE_FOREGROUND_ADMISSION_MIN_SIZE_BYTES`
-  - smallest direct `PutObject` that takes a permit; unknown-size requests always do.
-  - default is `33554432` (32 MiB).
-- `RUSTFS_PUT_LARGE_FOREGROUND_ADMISSION_WAIT_TIMEOUT_MS`
-  - how long a direct `PutObject` waits for a permit before returning S3 `SlowDown`.
-  - default is `250`.
-- `RUSTFS_PUT_MULTIPART_FOREGROUND_ADMISSION_MIN_SIZE_BYTES`
-  - smallest `UploadPart` that takes a permit; `0` gates every part.
-  - default is `0`.
-- `RUSTFS_PUT_MULTIPART_FOREGROUND_ADMISSION_WAIT_TIMEOUT_MS`
-  - how long an `UploadPart` waits in the bounded queue for a permit before returning S3 `SlowDown`; `0` rejects immediately when the pool is full.
-  - default is `10000`. Parts wait before body ingest, so SDK-default clients that send every part of an upload concurrently drain through the pool instead of failing on a full pool.
-  - RustFS does not read the request body while a part is queued, so the client's socket write stalls for the whole wait and whatever timeout the client or an intermediary has configured competes with this value. Keep it with margin below the shortest such timeout in use (botocore applies its 60 s `connect_timeout` to the body write; the AWS SDK for Java v2 has a 30 s socket write timeout; reverse proxies add their own body timeouts); a wait that outlives the client timeout surfaces as a dropped connection instead of `SlowDown`.
-- `RUSTFS_PUT_MULTIPART_FOREGROUND_ADMISSION_MAX_PENDING`
-  - maximum `UploadPart` requests waiting for a permit at once; parts beyond it return `SlowDown` without waiting.
-  - default is `0`, which derives 16 times the permit limit (512 at stock settings).
-  - each queued HTTP/1 part holds whatever unread body the client already pushed into the connection's kernel receive buffer (an HTTP/2 part holds up to its flow-control window in process memory), so this depth also bounds that memory. RustFS leaves the receive buffer to kernel autotuning (see `RUSTFS_HTTP_SOCKET_RECV_BUFFER_BYTES` below), which keeps an unread connection at the kernel's initial size (128 KiB on current Linux).
-- `RUSTFS_PUT_FOREGROUND_ADMISSION_ENABLE`, `RUSTFS_PUT_FOREGROUND_ADMISSION_LIMIT`, `RUSTFS_PUT_FOREGROUND_ADMISSION_WAIT_TIMEOUT_MS`
-  - experimental strict gate that applies to every foreground write regardless of size and replaces the pool above when enabled.
-  - default is disabled; enabling it with limit `0` disables foreground write admission entirely.
-
-## HTTP listener socket environment variables
-
-- `RUSTFS_HTTP_SOCKET_RECV_BUFFER_BYTES`
-  - fixed `SO_RCVBUF` for the API listener, inherited by every accepted socket; `0` leaves the receive buffer to kernel autotuning.
-  - default is `0`. Earlier releases hard-coded 4 MiB, which Linux doubles to 8 MiB and which disables autotuning, so every connection whose body was not being read yet (a multipart part queued for a foreground write permit) could accumulate up to 8 MiB of unread body in kernel memory; at SDK-default multipart concurrency that was enough to push a node into TCP memory pressure.
-  - with autotuning the per-connection receive ceiling is the kernel's (`net.ipv4.tcp_rmem` max, 6 MiB on stock Linux) instead of the former fixed 8 MiB, so a single very high-bandwidth-delay connection may see a somewhat lower ceiling; raise `net.ipv4.tcp_rmem` first, and set this variable only on kernels without receive-buffer autotuning (illumos/Solaris) or where the sysctl cannot be changed.
-  - the send buffer stays fixed at 4 MiB because the stock Linux send autotuning ceiling (`net.ipv4.tcp_wmem` max, 4 MiB) is lower than a GB-level response stream needs.
-
-## Remote tier timeout environment variables
-
-- `RUSTFS_TIER_REMOTE_CONNECT_TIMEOUT_SECS`
-  - remote tier TCP connect timeout.
-  - default is `10`.
-  - must be positive; zero fails tier client initialization, while an invalid integer is logged and falls back to the default.
-- `RUSTFS_TIER_REMOTE_REQUEST_TIMEOUT_SECS`
-  - remote tier request timeout through response headers.
-  - default is `86400` so large transition uploads keep a production-safe budget.
-  - must be positive; zero fails tier client initialization, while an invalid integer is logged and falls back to the default. Very large values are accepted and act as a correspondingly long budget.
-- `RUSTFS_TIER_REMOTE_RESPONSE_BODY_IDLE_TIMEOUT_SECS`
-  - maximum idle time between remote tier response-body chunks.
-  - default is `60`; the timer resets only when non-empty body data keeps progressing.
-  - must be positive; zero fails tier client initialization, while an invalid integer is logged and falls back to the default.

-## Admin peer probe timeout

-- `RUSTFS_ADMIN_PEER_PROBE_TIMEOUT_SECS`
-  - total per-peer budget for the `server_info`/`storage_info` admin probe round; `server_info` may reconnect once and `storage_info` remains a single attempt.
-  - default is `10` seconds, preserving the previous two-attempt worst-case budget.
-  - values must be positive; `0` or an invalid value falls back to the default, and values above `60` are clamped to `60`.
-  - the setting is read by the aggregating node only; it does not change the internode RPC wire contract. Any retry shares one round deadline rather than receiving a fresh timeout.

 ## Startup filesystem boundary policy

-**Endpoint blackhole scenario skipped** — `heal_erasure_disk_rebuild_test::tests::test_cluster_root_heal_recovers_after_target_endpoint_blackhole` installs a loopback `iptables` DROP rule and therefore needs `CAP_NET_ADMIN` (root or passwordless `sudo -n iptables`). A host where `iptables` is missing or cannot read the OUTPUT chain (typical inside an unprivileged container, where the nf_tables backend reports "Permission denied" even under `sudo`) logs a `heal_interruption_skipped` warning and returns without exercising heal. Set `RUSTFS_E2E_REQUIRE_NET_FAULT_INJECTION=1` on lanes that do provision the capability so a broken runner fails instead of skipping.

-//! 4-node upgrade coverage for historical objects and IAM AK/SK.

-//! Complements `upgrade_compatibility_test` (single-node SSE/multipart and
-//! mixed-version listing). This module pins the distributed contract the
-//! hardware upgrade chain is meant to catch: after a 4-node upgrade, objects
-//! written on the previous release still read back, and IAM user credentials
-//! created before the upgrade still authenticate.
-//!
-//! Requires `RUSTFS_UPGRADE_SOURCE_BINARY` pointing at the pinned previous
-//! release. The `e2e-distributed` workflow downloads that binary; a local run
-//! without it fails closed rather than skipping.
