+# Adversarial Review Shape
+
+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.

+description: Assess whether a GitHub issue is fixed, needs implementation, or can be closed by checking related work and current code. Use for issue completion/triage requests. Status questions are read-only; comment, close, or change labels only when the conversation authorizes that action.
+---
+
+# Issue Triage
+
+Use this skill when the user provides a GitHub issue URL and asks "can this be closed?", "is this already implemented?", "check completion status", or similar triage questions.
+
+## Workflow
+
+### 1. Fetch issue context
+
+```bash
+gh issue view <N> --repo <owner/repo> --json title,body,state,comments,labels,updatedAt
+```
+
+Read the issue body to understand what was requested. Extract:
+- The specific feature/fix/behavior described.
+- Any linked PRs or commits mentioned in the body or comments.
+- Any checklist items or sub-issues.
+
+Resolve the issue repository and implementation repository separately (for example, `rustfs/backlog` tracks work in `rustfs/rustfs`). Pass the implementation repository explicitly to PR queries; the current checkout may belong to another repository.
+
+### 2. Search for related work
+
+Search git history for commits referencing the issue:
+```bash
+git log --oneline --all --grep="<N>" | head -30
+```
+
+Search for related PRs:
+```bash
+gh pr list --repo <implementation-repo> --search "<issue-url>" --state all --json number,title,state,mergedAt
+```
+
+Also search qualified issue references and subject keywords; for same-repository
+issues, include `#<N>`. Follow explicit links even without a text match. A search
+page with no match does not prove the work is absent.
+
+If the issue mentions specific PRs, check their status:
+```bash
+gh pr view <PR_N> --repo <implementation-repo> --json state,mergedAt,title,mergeCommit,baseRefName
+```
+
+### 3. Verify implementation
+
+Fetch the implementation repository's current base branch. For each merged candidate, verify its merge commit is present and inspect the current code for the claimed behavior; a commit message match alone is not proof:
+```bash
+git fetch <implementation-remote> <base-branch>
+git merge-base --is-ancestor <merge-commit> <implementation-remote>/<base-branch>
+```
+
+If the issue describes a specific defect, inspect the fetched base's code rather than assuming the current checkout contains it:
+```bash
+git show <implementation-remote>/<base-branch>:crates/<relevant>/src/<file>.rs
+```
+
+For issues with checklists, verify each item individually. If sub-items are tracked as separate issues, check those too:
+```bash
+gh issue view <SUB_N> --repo <owner/repo> --json state
+```
+
+### 4. Determine verdict
+
+- **All items fixed and merged**: Recommend closing; name the verified PRs and behavior.
+- **Some items fixed, some remaining**: Keep open; report each remaining item.
+- **Not yet implemented**: Keep open; report what remains.
+- **Superseded or no longer relevant**: Recommend closing with evidence.
+
+### 5. Take action
+
+For a status-only request, return the assessment without GitHub writes. If commenting, closing, or label edits are authorized, perform only those actions; do not ask again for authority already given. Prepare the final assessment before asking for any missing authority. Write `rustfs/backlog` issue content in Chinese.
+
+Close with comment:
+```bash
+gh issue close <N> --repo <owner/repo> --comment "<body>"
+```
+
+Comment without closing:
+```bash
+gh issue comment <N> --repo <owner/repo> --body-file /tmp/triage.md
+```
+
+Update labels only when label changes are authorized, using existing repository labels; never add tool-specific labels:
+```bash
+gh issue edit <N> --repo <owner/repo> --add-label "<existing-label>"
+```
+
+Always use `--body-file` for multiline content, never inline `--body`.
+
+### 6. Handle multi-issue batches
+
+When the user asks to check multiple issues (e.g., "check all issues by user X" or "scan backlog for closable issues"):
+1. List the full requested scope with pagination (for example `gh api --paginate 'repos/<repo>/issues?state=open&per_page=100'`, excluding entries with `pull_request`). Add an author filter only when the user requested one; the default page/limit is not evidence that all issues were checked.
+2. For each issue, run steps 1-5 above.
+3. Report a summary table of all triaged issues with verdicts.
+
+## Report
+
+Identify the issue and current state, verified implementation/PR evidence,
+remaining items, verdict, and action actually taken. Use a table for batches;
+a single issue does not require a heading for each field. Follow step 4's
+verdicts without repeating the assessment in another template.
+
+## Notes
+
+- The user may ask in Chinese ("是否可以关闭", "检查完成情况"); respond in the same language.
+- When closing, always include a summary of what was fixed and which PRs resolved it — this creates a useful audit trail.
+- For issues in `rustfs/backlog`, use `--repo rustfs/backlog`.
+- For issues in `rustfs/rustfs`, use `--repo rustfs/rustfs`.
+- If the issue has sub-issues (GitHub sub-issues API), check each one's state before declaring the parent complete.

+# PR Review
+
+Use this skill for PR context and review delivery. An ordinary review request is read-only unless the conversation also authorizes posting or fixes. Reuse that authorization without asking again; prepare the review before requesting any missing publication approval.
+
+## Prerequisites
+
+- Follow root `AGENTS.md`; classify risk with the [review policy](../../references/adversarial-validation.md) and consult relevant [change-style and boundary rules](../../references/implementation.md).
+- Select `code-change-verification` for ordinary review or `adversarial-validation` for explicitly adversarial, substantial, or high-risk review; do not run both on the same diff.
+
+## Workflow
+
+### 1. Gather PR context
+
+```bash
+gh pr view <N> --repo <owner/repo> --json title,author,state,body,additions,deletions,changedFiles,commits,baseRefName,headRefName,baseRefOid,headRefOid
+gh pr diff <N> --repo <owner/repo> --name-only
+```
+
+Read the PR body and linked issues to understand the change's purpose. If the PR references an issue, fetch that too:
+```bash
+gh issue view <ISSUE> --repo <issue-owner/repo> --json title,body,state
+```
+
+### 2. Fetch the diff and classify the change
+
+```bash
+git fetch <repo-remote> <baseRefName> refs/pull/<N>/head
+git diff <baseRefOid>...<headRefOid> --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.
+
+### 3. Review the changed behavior
+
+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.
+
+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.
+
+### 4. Check CI status
+
+```bash
+gh pr checks <N> --repo <owner/repo>
+```
+
+Investigate a failed check when it bears on a finding or the user requested CI diagnosis/merge readiness:
+```bash
+gh run view --repo <owner/repo> --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.
+
+### 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.
+
+### 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:
+```bash
+# Request changes
+gh pr review <N> --repo <owner/repo> --request-changes --body-file /tmp/pr_review.md
+
+# Approve
+gh pr review <N> --repo <owner/repo> --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
+```
+
+For authorized inline comments, use [the submission example](references/posting.md).
+
+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.
+
+## 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.

+This skill orchestrates a full release. It wraps `rustfs-release-version-bump` (invoked here with the authorized commit/push/PR scope) with a mandatory preview-tag validation loop before the final tag is published.
 
-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.
+The binary reports its build tag (`build::TAG` via shadow_rs; `SHORT_VERSION` in
+`rustfs/src/config/cli.rs`), and `build.yml` derives asset names and preview
+classification from that tag. Cargo.toml supplies only the no-tag fallback.
+Preview and final tags must therefore share the validated source commit;
+their tag-dependent version and asset names differ. The channel and cleanup

 ### 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.
-
-1. Read the latest published Console tag and compare it with Console `main`:
-
-```bash
-CONSOLE_REPO="rustfs/console"
-CONSOLE_LATEST=$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)
-gh api "repos/${CONSOLE_REPO}/compare/${CONSOLE_LATEST}...main" \
-  --jq '{status, ahead_by, behind_by, commits: [.commits[] | {sha, message: .commit.message}]}'
-```
-
-- `ahead_by == 0`: no merged Console change is waiting for release. Still verify the current latest asset using step 4, then continue to Phase 1.
-- `ahead_by > 0` and `behind_by == 0`: publish Console before continuing. Report the merged commits and select the next unused `vX.Y.Z` tag. Default to the next patch version when the changes are fixes or backward-compatible UI work; stop for confirmation if a minor/major bump is plausible.
-- 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:
-
-```bash
-CONSOLE_SCRATCH=$(mktemp -d)
-gh repo clone "$CONSOLE_REPO" "$CONSOLE_SCRATCH/console"
-git -C "$CONSOLE_SCRATCH/console" fetch origin main --tags
-CONSOLE_HASH=$(git -C "$CONSOLE_SCRATCH/console" rev-parse origin/main)
-git -C "$CONSOLE_SCRATCH/console" tag --points-at "$CONSOLE_HASH" 'v*'
-gh run list -R "$CONSOLE_REPO" --workflow release.yml --commit "$CONSOLE_HASH" --limit 5
-```
-
-If no release exists or is running for `CONSOLE_HASH`, create the selected annotated tag at that exact hash and push it:
-
-```bash
-git -C "$CONSOLE_SCRATCH/console" tag -a "<console-tag>" -m "Release <console-tag>" "$CONSOLE_HASH"
-git -C "$CONSOLE_SCRATCH/console" push origin "<console-tag>"
-```
-
-Console tags include the `v` prefix. Pushing the tag triggers `.github/workflows/release.yml` (`🚀 Release`). Remove `CONSOLE_SCRATCH` after the gate completes.
-
-3. Find the exact tag run and wait for completion:
-
-```bash
-gh run list -R "$CONSOLE_REPO" --workflow release.yml --branch "<console-tag>" --limit 1
-gh run watch -R "$CONSOLE_REPO" "<console-run-id>" --exit-status
-```
-
-4. Block until the published Release is non-draft, the latest endpoint returns the expected tag, and `rustfs-console-<console-tag>.zip` is uploaded, non-empty, and carries a `sha256:` digest:
-
-```bash
-gh release view -R "$CONSOLE_REPO" "<console-tag>" --json isDraft,isPrerelease,assets,url
-test "$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)" = "<console-tag>"

+- `GHSA-g8w9-qw9q-fghr`: a valid presigned `PutObject` accepted extra `x-amz-tagging`, website redirect, and storage-class headers omitted from `SignedHeaders`. Lesson: a presigned URL is a bounded capability; reject `x-amz-*` headers that are not cryptographically bound by the signature so unsigned metadata cannot change authorization, lifecycle, redirect, cost, or durability semantics.
 - `GHSA-3ppv-fx5m-m749`: explicit `versionId` reads and copy sources authorized `s3:GetObject` instead of `s3:GetObjectVersion`. Lesson: version-specific object access must select version-specific actions for direct reads, `CopyObject`, and `UploadPartCopy`, with tests proving the backend is not reached on denial.
 - `GHSA-x298-9x87-fvjq`: anonymous `ListObjectVersions` fell back to `ListBucket` and returned before public-access-block gates. Lesson: compatibility fallbacks must converge on the same post-authorization checks as direct grants, especially `RestrictPublicBuckets` and anonymous data-plane denies.
 - `GHSA-mx42-j6wv-px98`: `UploadPartCopy` missed source authorization and allowed cross-bucket object exfiltration. Lesson: multipart copy must enforce the same source and destination contract as `CopyObject`.

 ### Serde deserialization and input validation
 
-- 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.
+- Reject unknown fields in untrusted S3 API XML/JSON, lifecycle, policy, and replication input where compatibility permits. Check the current type and supported payload fixtures; do not infer the repository's current coverage from an older audit. Where extra fields are part of the compatibility contract, validate security-critical values explicitly.
 - `#[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()` or clamp.
+- 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.
 - XML config typos (e.g., `"NoncurentDays"` instead of `"NoncurrentDays"`) are silently accepted when `deny_unknown_fields` is absent. Lesson: strict deserialization prevents silent misconfiguration that could cause data loss or unexpected retention behavior.

 ## Usage assumptions
 - Focus scope is either changed lines/files, a module, or the whole repository.
-- Coverage artifact must be generated or provided in a supported format.
+- Reuse a supplied coverage artifact when its revision, scope, and format match.
 - If required context is missing, call out assumptions explicitly before proposing work.
 
 ## Workflow
 
 1. Define scope and baseline
-   - Confirm target language, framework, and branch.
-   - Confirm whether the scope is changed files only or full-repo.
+   - 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.
 
-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.
+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.
 
 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).
-   - Keep shortlist to 5–8 gaps.
+   - Report up to 5–8 evidenced gaps; do not pad a small scope.
    - For each gap, capture: file, lines, uncovered branches, and estimated risk score.
 
 4. Propose high-impact tests
-   - 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`).
+   - 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.
 
 5. Close with validation plan
    - State which gaps remain after proposals.
-   - Provide concrete verification command and acceptance threshold.
+   - Give a scoped verification command and behavior-based acceptance criterion;
+     use a coverage threshold only when the task or repository requires one.
    - List assumptions or blockers (environment, fixtures, flaky dependencies).

+# The four cases in `on_demand_migration::interop_test` take their source from
+# the environment (`RUSTFS_ODM_INTEROP_*`, documented on the constants in
+# `crates/e2e_test/src/on_demand_migration/common.rs`), so the same bodies run
+# against the in-process fake source locally and against a MinIO container or a
+# real cloud provider in the lane. The cloud jobs narrow this profile with their
+# own `-E` filter to the three-case minimum (GET miss, HEAD miss, merged list
+# pagination) and pass `--no-tests=fail` so a rename cannot silently select
+# nothing; the MinIO job runs the whole profile, backfill included.
+#
+# These cases are deliberately absent from every other lane: without an
+# interop source they only re-prove what `get_basic_test` and
+# `list_through_test` already cover in e2e-smoke and e2e-full. The committed
+# selection digest is the guard against a rename dropping one of them.

 ## Summary of Changes
 <!--
-Briefly explain what changed and why reviewers should accept it.
-Focus on behavior, compatibility, and review-relevant context.
+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.
 -->
 
 ## Verification
 <!--
-List the commands or checks you ran, for example:
-- `make pre-commit`
+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.
 
-Use N/A only when verification is not applicable.
+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.

+# On-demand migration provider interop (rustfs/backlog#2167, ODM-20).
+#
+# The in-process fake source that the merge-gate ODM suite runs against covers
+# the protocol semantics, but real implementations differ in path-style vs
+# virtual-host addressing, region handling, ETag shape, list pagination and
+# rate limiting. This lane runs the same case bodies
+# (crates/e2e_test/src/on_demand_migration/interop_test.rs) against real
+# sources; the source is injected through RUSTFS_ODM_INTEROP_* environment
+# variables, so nothing about the cases is duplicated per provider.
+#
+# Report-only and scheduled. It is never a required check and must not be
+# promoted to one: it depends on third-party endpoints and on repository
+# secrets that a fork does not have.
+#
+# Jobs:
+#   * minio-source runs the whole e2e-odm-interop profile — read-through,
+#     HEAD passthrough, merged list pagination and a backfill — against a
+#     pinned MinIO container. The backfill is sized at 5,000 objects here: the
+#     fake source retains at most 4,096 object versions and 4,096 journal
+#     entries, so the merge-gate backfill coverage cannot go past that, and a
+#     real source is where a production-shaped batch belongs.
+#   * cloud-source runs the three-case minimum (GET miss, HEAD miss, merged
+#     list pagination) against AWS S3, Cloudflare R2 and the GCS XML
+#     interoperability API. Each provider is skipped with a summary note when
+#     its ODM_INTEROP_* repository secrets are absent, which is the normal
+#     state on a fork and in any clone of this repository.
+#
+# Every job uploads one JSON report per provider naming the cases, their
+# timings and the source request accounting.

-description: Triage a GitHub issue — determine if it is already fixed, needs implementation, or should be closed. Searches related commits and PRs, verifies implementation status, and posts a triage comment or closes the issue. Use when the user provides an issue URL and asks whether it can be closed or needs work.
----
-
-# Issue Triage
-
-Use this skill when the user provides a GitHub issue URL and asks "can this be closed?", "is this already implemented?", "check completion status", or similar triage questions.
-
-## Workflow
-
-### 1. Fetch issue context
-
-```bash
-gh issue view <N> --repo <owner/repo> --json title,body,state,comments,labels,updatedAt
-```
-
-Read the issue body to understand what was requested. Extract:
-- The specific feature/fix/behavior described.
-- Any linked PRs or commits mentioned in the body or comments.
-- Any checklist items or sub-issues.
-
-### 2. Search for related work
-
-Search git history for commits referencing the issue:
-```bash
-git log --oneline --all --grep="<N>" | head -30
-```
-
-Search for related PRs:
-```bash
-gh pr list --search "fixes #<N> OR closes #<N> OR #<N>" --state all --json number,title,state,mergedAt
-```
-
-If the issue mentions specific PRs, check their status:
-```bash
-gh pr view <PR_N> --json state,mergedAt,title
-```
-
-### 3. Verify implementation
-
-For each linked or related PR that is merged, verify the fix is actually present on the current main branch:
-```bash
-git log --oneline main | grep -i "<keyword>"
-# or
-git log --oneline main --grep="<PR_N>"
-```
-
-If the issue describes a specific defect, check the relevant code to confirm the fix is in place:
-```bash
-grep -n "<pattern>" crates/<relevant>/src/<file>.rs
-```
-
-For issues with checklists, verify each item individually. If sub-items are tracked as separate issues, check those too:
-```bash
-gh issue view <SUB_N> --repo <owner/repo> --json state
-```
-
-### 4. Determine verdict
-
-- **All items fixed and merged**: Close with a summary comment listing what was fixed and which PRs.
-- **Some items fixed, some remaining**: Comment with status of each item. Do not close.
-- **Not yet implemented**: Comment with a summary of what remains. Do not close.
-- **Superseded or no longer relevant**: Close with explanation.
-
-### 5. Take action
-
-Close with comment:
-```bash
-gh issue close <N> --repo <owner/repo> --comment "<body>"
-```
-
-Comment without closing:
-```bash
-gh issue comment <N> --repo <owner/repo> --body-file /tmp/triage.md
-```
-
-Update issue labels if needed:
-```bash
-gh issue edit <N> --repo <owner/repo> --add-label "completed" --remove-label "needs-triage"
-```
-
-Always use `--body-file` for multiline content, never inline `--body`.
-
-### 6. Handle multi-issue batches
-
-When the user asks to check multiple issues (e.g., "check all issues by user X" or "scan backlog for closable issues"):
-1. List the issues: `gh issue list --repo <repo> --author <user> --state open --json number,title,updatedAt`
-2. For each issue, run steps 1-5 above.
-3. Report a summary table of all triaged issues with verdicts.
-
-## Output format
-
-### Issue Triage: #<N> — <title>
-
-**State**: OPEN / CLOSED
-**Linked PRs**: <list with merge status>
-
-#### Assessment
-<what was requested vs what is implemented>
-
-#### Verdict
-- Close — all items resolved by <PR list>
-- Keep open — <remaining items>
-- Not started — <what needs to be done>
-
-#### Action taken
-- Closed with comment / Commented / No action
-
-## Notes
-
-- The user may ask in Chinese ("是否可以关闭", "检查完成情况"); respond in the same language.
-- When closing, always include a summary of what was fixed and which PRs resolved it — this creates a useful audit trail.
-- For issues in `rustfs/backlog`, use `--repo rustfs/backlog`.
-- For issues in `rustfs/rustfs`, use `--repo rustfs/rustfs`.
-- If the issue has sub-issues (GitHub sub-issues API), check each one's state before declaring the parent complete.

-description: Review a GitHub PR end-to-end from a URL or number — fetch metadata, inspect the diff, run multi-role adversarial review, check CI status, and post the review comment. Use when the user provides a PR link and asks to review it.
----
-
-# PR Review
-
-Use this skill when the user provides a GitHub PR URL or number and asks to review it. This covers the full review lifecycle: data gathering, code review, CI verification, and posting the result.
-
-## Prerequisites
-
-- Read `AGENTS.md` for the repository's adversarial validation policy and change-style rules.
-- The `adversarial-validation` skill handles the review role playbooks; this skill orchestrates the workflow around it.
-
-## Workflow
-
-### 1. Gather PR context
-
-```bash
-gh pr view <N> --json title,author,state,body,additions,deletions,changedFiles,commits,baseRefName,headRefName
-gh pr diff <N> --name-only
-```
-
-Read the PR body and linked issues to understand the change's purpose. If the PR references an issue, fetch that too:
-```bash
-gh issue view <ISSUE> --json title,body,state
-```
-
-### 2. Fetch the diff and classify the change
-
-```bash
-git fetch origin pull/<N>/head:pr-<N>
-git diff main...pr-<N> --stat
-```
-
-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. Cluster changed files and delegate review
-
-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.
-
-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>
-```
-
-If any checks fail, investigate:
-```bash
-gh run view --log-failed --job=<JOB_ID>
-```
-
-Determine whether failures are pre-existing (on main), flaky, or caused by the PR.
-
-### 5. Synthesize findings
-
-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
-
-Write the review body to a temp file and post via CLI:
-```bash
-# Request changes
-gh pr review <N> --request-changes --body-file /tmp/pr_review.md
-
-# Approve
-gh pr review <N> --approve --body-file /tmp/pr_review.md
-
-# Comment only (no verdict)
-gh pr review <N> --comment --body-file /tmp/pr_review.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
-
-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
-
-### PR Review: #<N> — <title>
-
-**Author**: <author>
-**Risk tier**: exempt | mechanical | standard | high-risk
-**Changed files**: <count> across <cluster count> clusters
-
-#### Summary
-<one-paragraph overview>
-
-#### Findings
-| Severity | Location | Finding |
-|----------|----------|---------|
-| critical | file:line | concrete failure scenario |
-
-#### CI Status
-- All checks pass / Failing: <details>
-
-#### Verdict
-APPROVE / REQUEST_CHANGES / COMMENT
-
-## 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 (>50 files), cluster aggressively and delegate in parallel to keep review time reasonable.

-  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.

 ## [Unreleased]
 
+### Replication
+
+- Object Lock replication PUTs now carry a required integrity header, fixing target rejection introduced by the plain-payload default ([#7097](https://github.com/rustfs/rustfs/pull/7097)). This changes the default outbound request for locked objects but adds no persisted format.
+- Multipart source objects stay on the multipart transport even when their checksum record is a whole-object checksum, so objects above the single-PUT limit remain replicable ([#7047](https://github.com/rustfs/rustfs/pull/7047)).
+- Targets that mint their own version IDs now use a per-target version ledger for tag, retention, legal-hold, and permanent-delete mutations; ambiguous pre-ledger matches fail with backoff instead of guessing ([#7368](https://github.com/rustfs/rustfs/pull/7368)). This adds dual-prefixed internal metadata keys that older readers ignore.
+- Single-part source checksums are forwarded as `x-amz-checksum-*` headers instead of user metadata, so the replica preserves checksum responses ([#7313](https://github.com/rustfs/rustfs/pull/7313)). This changes the default outbound headers for checksummed objects.
+- Site-replication outage recovery now uses a bounded 30-second retry drain plus the 600-second full reconciliation pass, persists destructive liabilities before local deletion, and fences replay settlement and peer edits ([#7148](https://github.com/rustfs/rustfs/pull/7148)). Persisted additions are optional and ignored by older readers.
+- IAM snapshot/deletion replay, target-assigned delete-marker purges, timestamp ordering, and best-effort peer broadcast now close the control-plane gaps found by the R6 review ([#7195](https://github.com/rustfs/rustfs/pull/7195)).
+- 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. See `docs/operations/site-replication-operations.md`.
+
+### Security
+- **Presigned URLs honour only signed headers** (GHSA-g8w9-qw9q-fghr): a SigV4 presigned request that carries an `x-amz-*` request header not listed in `X-Amz-SignedHeaders` is now rejected with `403 AccessDenied` ("There were headers present in the request which were not signed"), matching AWS S3. Previously the holder of a presigned `PutObject` URL could add unsigned `x-amz-tagging`, `x-amz-storage-class`, `x-amz-website-redirect-location`, ACL, metadata, Object Lock or SSE headers and have them applied. Presigners that intend a property must set it before signing so the SDK lists the header in `SignedHeaders`; `x-amz-cf-id` (CloudFront) remains tolerated unsigned. Header-signed SigV4 and SigV2 requests are unchanged.
+
 ### Fixed
+- **Fresh multi-pool bootstrap with distinct format creators**: a new deployment whose pools have their first endpoint on different nodes (for example two single-node pools) could never publish its initial `pool.bin`: each node held fresh-bootstrap proof only for the pool it formatted, the deployment-wide proof collapsed to none, and every node died with `pool metadata recovery required: no durable bootstrap identity or pool.bin replica is available` after the startup retry budget. The first pool's creator now mints the pending cluster identity on its own pool, every other creator copies that nonce-bound identity onto the pool it formatted first-hand, and the elected writer publishes `pool.bin` once every pool replica carries the same pending identity. Corrupt or disagreeing replicas, pools that merely have a format, expansion pools joining an initialized deployment, and restarts without first-hand proof still fail closed. Non-elected nodes that start before `pool.bin` exists, and the elected writer while it waits for the other creators, no longer latch their pool-metadata write gate for the life of the process. Refs rustfs/backlog#2338, rustfs/backlog#2375.
+- **Lock RPC timeout storms** (#7363): the remote lock client no longer evicts and re-dials the shared internode HTTP/2 channel on every request deadline. A timeout evicts only when the peer has not completed any lock RPC for two deadlines, evictions and transport-failure re-dials are rate limited per peer (`RUSTFS_OBJECT_LOCK_RPC_EVICTION_COOLDOWN_MS`, default 5 s), and a timed-out request is left running instead of being reset (bounded per peer by `RUSTFS_OBJECT_LOCK_RPC_DETACHED_LIMIT`, default 256), so a slow lock endpoint can no longer drive the `RST_STREAM`/`GOAWAY too_many_resets`/reconnect loop. A lock granted after its caller timed out is released immediately, and unlocks that fail the quick retries continue on a deferred 1/2/4/8/16 s schedule before the server lease reclaims them. New `rustfs_remote_lock_*` metrics cover timeouts, evictions, suppressed evictions, detached streams, late completions and late releases per peer. Operator guide at `docs/operations/lock-rpc-storm-protection.md`.
+- **KMS failures on the S3 data path carry an actionable status**: only "key not found" and a backend outage were classified; every other KMS failure — a disabled or pending-deletion key, a denied KMS grant, an encryption-context mismatch, an unsupported algorithm, a credential or timeout failure, a capability the backend does not have — collapsed onto `500 InternalError`. SDKs therefore applied exponential backoff to configuration errors that no retry can fix, and monitoring filed every one of them as a server fault. Unusable-key and request-side failures now return `400`, a denied grant `403`, transient backend failures `503` — including a key store the backend could not read, so an outage stays distinguishable from a missing key all the way to the client — and a missing backend capability `501`. Damaged or unreadable key material still returns `500`, which is what it is.
+- **SSE-C on buckets with default encryption**: a `PutObject` carrying a valid SSE-C header triple on a bucket that has default encryption configured no longer fails with `400 InvalidArgument` ("The SSE-C and managed server-side encryption headers cannot be used together"). PUT and the POST-object/extract path resolved the bucket default with a hard-coded "no explicit SSE-C" flag, so the default was layered onto the request and then tripped the request's own mutual-exclusion check; an SSE-C request now suppresses the bucket default on all three write paths, matching COPY and AWS S3. Every bucket with default encryption previously refused SSE-C single PUTs outright, while `CreateMultipartUpload` on the same bucket succeeded.
+- **Explicit SSE-S3 on SSE-KMS-default buckets**: `x-amz-server-side-encryption: AES256` against a bucket whose default is `aws:kms` no longer fails with `400 InvalidArgument`. The bucket default's KMS key id was inherited independently of the effective algorithm, producing a self-contradictory `AES256` + key-id pair; the key id is now inherited only when the effective algorithm is `aws:kms`. `PutBucketEncryption` fills in a default key id automatically, so this affected nearly every SSE-KMS-default bucket.
+- **Restore of encrypted or compressed multipart objects (silent data corruption)**: restoring a multipart object from a remote tier addressed the tier in *plaintext* coordinates while the copy-back reads the *stored* representation. Every part received a misaligned slice of the remote object whose length still satisfied the range, the hash reader and the completion size check, so the restore reported success and replaced the object's bytes. Restore now accumulates stored part sizes, passes the stored length to the hash reader alongside the plaintext length, and validates against the stored size. Objects restored by an affected release must be re-restored from the tier or recovered from a backup — this release does not detect or repair them retroactively.
+- **Restore no longer drifts the object ETag**: the copy-back digests stored (encrypted or compressed) bytes, so the recomputed MD5 is not the object's public ETag. Single-part and multipart restores now preserve the original object ETag, and each restored part keeps its own recorded part ETag.
+- **ILM archive no longer forwards encryption metadata to the tier**: transition requests carried the object's SSE headers and the RustFS-wrapped data key as request headers. Any S3 target rejected an SSE-C archive outright (`400`, no key supplied), an SSE-KMS archive asked the target to encrypt a second time under a key id it does not own, and the wrapped DEK left the cluster. The archive request now strips every SSE header and encryption marker using the same predicate the replication path uses; the local `xl.meta` keeps all of it, so read-through and restore are unaffected.
+- **KMS reload is no longer a no-op on a node whose KMS failed to start**: `POST /rustfs/admin/v3/kms/reload` short-circuited whenever the persisted configuration matched the in-memory one byte for byte. A node whose KMS failed to start (for example Vault briefly unreachable during a rolling restart) keeps that configuration and sits in `Error`, so the documented recovery call returned "reloaded successfully" while leaving the node down — and did the same on every peer through the reload broadcast. Reload now short-circuits only for a service that is actually running, and otherwise reconfigures, which starts the service.
+- **AWS KMS capability reporting**: the AWS backend no longer advertises `versioning` support through `GET /rustfs/admin/v3/kms/status`. AWS KMS key versions are not enumerable through this backend, as the backend documentation already stated.
+- **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.
 
 ### Added
+- **On-Demand Migration**: Lazy, pull-style migration of an existing S3-compatible bucket into RustFS. A local bucket is attached to an external source bucket; a GET for a key that does not exist locally fetches it from the source, streams it to the client, and stores it locally in the same pass, so every later read is served locally. The module is on by default; set `RUSTFS_ON_DEMAND_MIGRATION_ENABLED=false` on every node to turn it off. A bucket with no source configured behaves exactly as before — the runtime never intervenes on its reads and makes no outbound call. Operator guide at `docs/operations/on-demand-migration.md`.
+  - Per-bucket configuration persisted as `on-demand-migration.json` in the bucket metadata: source provider (`s3`, `aws`, `minio`, `rustfs`, `r2`, `gcs`), endpoint, region, addressing style, credentials and TLS material, an optional key-prefix filter and source-prefix rewrite, and a policy block covering the inline size threshold, multipart part size, concurrency, queue capacity, timeouts, bandwidth limit and negative-cache TTL
+  - Admin routes under `/rustfs/admin/v3/on-demand-migration/{bucket}`: `PUT` (with `?dry-run=true` to validate and probe the source without saving), `GET`, `DELETE`, `GET .../status`, plus `POST .../backfill?op=start|cancel` and `GET .../backfill` for the background full-backfill job with its resumable checkpoint. Authorized by the new `admin:GetBucketOnDemandMigration` and `admin:SetBucketOnDemandMigration` actions; every response redacts `secret_key` and `session_token`
+  - 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
 - **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

 ### Changed
+- **Encryption and KMS work merged since `1.0.0-rc.5`** (entries were missing from this section):
+  - **Persisted KMS configuration secrets** are sealed field-by-field with `RUSTFS_KMS_CONFIG_SECRET`. **When the variable is unset the secrets are persisted in cleartext and the server only warns** (`persisted KMS configuration carries cleartext secrets`); it never refuses the write. Set it, identically, on every node, and re-save the configuration to seal an existing one.
+  - **New v2 ciphertext frame format** with per-frame index binding and final-frame authentication. Its write switch `RUSTFS_ENCRYPTION_FRAME_V2` is **off by default**: v2 frames are unreadable by nodes without v2 read support, and encrypted ciphertext travels verbatim through transition, decommission and SSE-C replication passthrough, so turn it on only after every node — and every RustFS warm/replication target that receives raw ciphertext — runs a release with v2 read support. Reading v2 objects needs no switch.
+  - **Per-key SSE-KMS authorization** (`RUSTFS_KMS_ENFORCE_SSE_KEY_POLICY`, default `false`). With it on, anonymous callers hold no KMS grants, so **a public bucket serving SSE-KMS objects is an incompatible combination** and those reads return `AccessDenied`.
+  - Envelope context binding as KMS AAD (`ENV_KMS_ENVELOPE_AAD`, off by default; a node that predates the field cannot open bound envelopes).
+  - Vault custom CA and mutual TLS; object-level DEK rewrap plus a batch rekey admin API; a backend-locality runtime signal on `kms/status`.
+  - Single-pass decryption for encrypted GET, and encrypted single-part closed-range seek — the latter is now **on by default** (`RUSTFS_ENCRYPTED_RANGE_SEEK`, default `true`; the switch remains as a kill switch).
+- **Vault static tokens are now tracked and renewed**: with `Token` authentication RustFS hard-coded "this token has no lease", so the renewal task never started and no remaining-TTL gauge was published. `vault token create` grants a 768-hour TTL by default, which turned a healthy-looking cluster into one where every KMS call returned 403 about a month later, with no self-healing short of a restart or reconfigure. RustFS now calls `auth/token/lookup-self` at login and adopts what Vault reports: a non-expiring token behaves exactly as before, an expiring renewable one is renewed at half TTL like the other auth methods, and an expiring non-renewable one logs `vault_static_token_not_renewable` and publishes its remaining TTL. The probe never fails the login: a token whose policy omits `lookup-self` (Vault's `default` policy grants it), or a Vault that is unreachable at that moment, logs `vault_static_token_lookup_failed` and falls back to the previous no-lease behaviour, so no deployment that works today stops working.
+- **SSE-C over a plaintext transport is reported**: AWS S3 and MinIO refuse an SSE-C request that did not arrive over TLS, because the customer key travels in a request header. RustFS accepted them on any transport and still does by default — flipping to a rejection inside a release window would break plaintext staging and test deployments. Each such request now increments `rustfs_ssec_plaintext_requests_total` and logs one `ssec_request_without_tls` warning per process, and `RUSTFS_SSE_C_REQUIRE_TLS=true` opts into the AWS `400` now. The default is expected to flip in a later release; confirm the counter reads zero first. The verdict is per connection: a TLS listener satisfies it, and so does an `https` protocol forwarded by a proxy the trusted-proxy configuration accepts.
+- **Local KMS backend on a distributed deployment says what actually breaks**: the backend keeps key material and its Argon2id salt on each node's own disk, so two nodes derive different keys from the same `master_key` and an object encrypted on one node cannot be decrypted on another — intermittent 500s behind a load balancer. Configuring it while the deployment is distributed now logs `kms_node_local_backend_in_distributed_deployment` and appends that consequence to the `kms/configure` response, instead of only the generic "development only" positioning warning. It remains a warning, not a gate.
+- **SSE-KMS is refused when no KMS is running (breaking)**: a write requesting `x-amz-server-side-encryption: aws:kms` on a node with no KMS service no longer succeeds. Earlier releases wrapped the data key with the node-local `RUSTFS_SSE_S3_MASTER_KEY` while still writing `aws:kms` and the requested key id into the object metadata — metadata that claimed a KMS protection the object never had, under a key that was never consulted. Such a request now returns `400 InvalidRequest` when KMS was never configured and `503` when a configured service is not running; the refusal is evaluated after the per-key authorization gate, so an unauthorized caller still receives `403 AccessDenied`. **Upgrade note:** a deployment that relied on this write succeeding will start receiving 4xx/503. Either configure a KMS, or request `AES256` and keep the documented SSE-S3 local-master-key fallback, which is unchanged. Objects already written this way remain readable.
+- **Legacy ciphertext nonce layouts are now locked per segment**: while decrypting a v1 segment, the reader locks onto whichever of the three historical nonce layouts decoded the segment's first non-zero-index frame and rejects any later frame that needs a different one. Because a frame encrypted at block index zero authenticates under the pre-`1.0.0-alpha.91` reused-part-nonce layout at any position, an attacker able to rewrite the underlying shards could previously replay it and have the forged plaintext returned with `200`. New `RUSTFS_ENCRYPTION_LEGACY_NONCE_FALLBACK` (default `true`) drops that third layout entirely when set to `false`, which closes the residual case of a stream built purely from repeats of frame zero. Turn it off only after migrating pre-alpha.91 encrypted objects (rewrite in place with CopyObject); see [KMS backend security properties](docs/operations/kms-backend-security.md) for what the v1 frame layout does and does not authenticate.
 - **HTTP Server Stack**: Integrated `KeystoneAuthLayer` middleware from `rustfs-keystone` crate into service stack (positioned after ReadinessGateLayer)
 - **Storage-class validation on startup (upgrade note)**: A persisted explicit storage class (`RUSTFS_STORAGE_CLASS_STANDARD` / `RUSTFS_STORAGE_CLASS_RRS`, for example `EC:2`) is now validated against the actual per-pool drive counts at startup and rejected when a pool cannot satisfy it. This is fail-closed and correct, but a cluster that persisted a storage class larger than a small or heterogeneous pool can hold (for example `EC:2` alongside a 2-drive pool), which earlier releases accepted and silently resolved to an invalid layout, will now refuse to start after upgrade. To recover, unset `RUSTFS_STORAGE_CLASS_STANDARD` so the server derives a valid per-pool default automatically, or set it to a value every pool can satisfy.
 - **IAMAuth**: Enhanced `get_secret_key()` to return empty secret for Keystone credentials (bypasses signature validation)

+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:

 make setup-hooks

-Or manually:
+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.
 
-```bash
-chmod +x .git/hooks/pre-commit
-```
+`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.
 
-With or without a hook, the expectation is the same: run `make pre-commit`
-before committing and `make pre-pr` before opening a pull request.
+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.

+- **RustFS KMS**: Vault (KV2 / Transit) and AWS KMS backends are supported for production. The `Local` and `Static` backends are for development and testing only. See [KMS backend security properties](docs/operations/kms-backend-security.md).
+- **Swift API / SFTP**: opt-in cargo features (`--features swift`, `--features sftp`, or `full`). FTPS and WebDAV are enabled in the default build.
+- **S3 Tables**: ships as an Iceberg REST Catalog with automated PyIceberg and DuckDB coverage; other engines and vendor profiles carry bounded claims listed in the [S3 Tables support matrix](docs/architecture/s3-tables-support-matrix.md).
+- **MinIO On-Disk Compatibility**: gated behind the `rio-v2` feature and not part of the default build. Objects MinIO encrypted are not readable by RustFS. See [MinIO file-format interoperability](docs/architecture/minio-file-format-compat.md).

+> **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.

+## 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.

 ## Troubleshooting
 
+**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.
