merge: sync main and preserve prepared delete ownership

Reject single, batch, and exact-version deletes before staging mutations.
Transfer real lifecycle ownership through detached deletion and reuse the
cleaner's existing owner to avoid a queued-writer deadlock.

Correct the physical-tail cancellation observer and cover disconnected PUT
publication plus managed delete refusal with four-node tests.

+Applies when changing code or running artifact-heavy work. Paths below
-
+are repository-relative. Read only the relevant sections during read-only review.
-## Shared Style Contract
-
-- Use the toolchain declared in `rust-toolchain.toml`, respect the minimum supported Rust version in `Cargo.toml`, and let `rustfmt.toml` and the configured Rust/Clippy lints define mechanical style. Do not override repository settings with personal formatter or lint preferences.
-- Follow the owning module's organization, imports, and domain terminology where repository rules leave a choice. Existing violations do not justify new ones; avoid unrelated cleanup in a focused change.
-- Rules using "must" or "do not" are requirements. Rules using "prefer" are defaults; depart when correctness, ownership, performance, or readability benefits justify it. Explain consequential tradeoffs, not every idiomatic choice. Where several approaches meet the contract equally well, the implementer chooses.
-- Follow the declared toolchain locally and the affected CI lane's toolchain for reproduction. The repository currently tracks `stable`; for a formatter/lint mismatch, compare `rustc -Vv`, `cargo fmt --version`, and `cargo clippy --version` with the failing run before changing code. Toolchain upgrades must keep local and CI settings aligned and pass their affected gates; do not silently raise `rust-version` or change lint policy to make a check pass.
 
 ## Worktree and Disk Hygiene
 
-- For a new task, start from the latest `origin/main` unless a different base is requested, and confirm the requested change is not already present. When continuing existing work or a PR, preserve its branch, base, and task-owned changes; do not restart it from `main`.

-- Preserve unrelated control flow. Restructure touched code only when needed for the requested behavior or an explicitly requested refactor; style preferences alone do not justify changing execution order or cleanup behavior.

-## Rust Style
-
-These repository-owned rules incorporate selected ideas from the [OpenCode style guide](https://github.com/anomalyco/opencode/blob/dev/AGENTS.md#style-guide), adapted to RustFS. That link is background, not an additional rule source. Apply these defaults to new or changed code; correctness and domain invariants take priority.
-
-- Default to immutable `let` bindings; use `mut` for actual state changes. Prefer `if` or `match` expressions when branches compute a value instead of initializing a placeholder and reassigning it.
-- Use type inference for obvious local values. Add annotations when inference needs help or the numeric, collection, or error type matters to understanding the code. Keep explicit types in function signatures and public contracts.
-- Keep the main path readable with guard clauses, `let ... else`, and `?` when immediate propagation is correct. Preserve explicit handling for recovery, cleanup, aggregation, and quorum decisions; `if`/`else` expressions and exhaustive `match` remain idiomatic.
-- Prefer readable iterator chains for straightforward mapping and filtering. Keep loops when they make state changes, early exits, or async operations clearer. Do not add intermediate collections or clones just to use iterators.
-- Inline trivial single-use expressions only when a binding adds no meaning. Keep names that explain domain concepts, aid debugging, or make ownership and guard lifetimes clear. Do not change lock release or drop timing for style.
-- Keep pure parsing, validation, and option-building helpers synchronous unless an async interface contract requires otherwise. This does not make blocking I/O or CPU-heavy work safe to run on async executor threads; offload it when needed to keep those threads responsive.
-
 ## Reuse and Boundary Rules
 
-- Before adding helpers, constants, fixtures, or wrappers, search the touched code and domain owner; check `crates/utils`, `crates/common`, and direct dependencies when they could own the behavior. Stop once the relevant reuse boundary is clear.
+- Before adding helpers, constants, fixtures, or wrappers, search the touched

+  direct dependencies.
-- For destructive actions such as delete or overwrite and for quorum decisions, check the relevant identity, generation, and authority under the operation's existing synchronization or precondition contract. A separate unguarded recheck does not prevent a check/use race.
+- Reuse requires matching semantics: normalization, error types, deadlines,

+  untrusted at every consumer.
+- Re-check boundary values immediately before destructive actions such as

+- Required values must return a typed error when absent or corrupt; do not use a
+  default that converts corruption into a plausible result.
+- Attach error context once where it is actionable. Do not erase typed errors
+  below aggregation or quorum layers.
 
 ## Rust Boundaries
 
-- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees. Stricter scoped prohibitions, including `crates/AGENTS.md`, still apply. Invalid client, disk, or peer data must return errors rather than trigger panics.
+- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees.
 - Public APIs do not return `Result<_, String>`. Library APIs use domain errors unless intentional erasure is part of the boundary contract; expose a stored inner error through `Error::source()`.
 - Numeric conversions must not silently truncate. Use fallible conversions for untrusted values; validate finiteness, sign, and range before float-to-integer conversion. Clamp/saturate only when required by the domain.
 - Do not add crate-root `#![allow(dead_code)]`.
 
 ## Naming
 
-Use Rust API naming: `SCREAMING_SNAKE_CASE` constants/statics, `snake_case` functions/variables/modules, and `PascalCase` types/traits. Name domain concepts and include units where a value would otherwise be ambiguous; do not optimize for short names. Do not rename public, serialized, or persisted fields merely to match a local style preference, or rename unrelated existing violations.

-
-- For new or changed public APIs, document the caller-visible behavior and relevant `# Errors`, `# Panics`, and `# Safety` conditions. Include a useful example or link to one when usage is non-obvious; avoid boilerplate sections that say nothing. Follow the [Rust API documentation guidelines](https://rust-lang.github.io/api-guidelines/documentation.html) within the scope of the change.
-- For async or storage APIs, state cancellation, retry/idempotency, partial-completion, ownership, and durability guarantees when callers rely on them. Make failure cleanup and commit points explicit in code and tests; do not imply atomicity that the implementation does not provide.
-- For protocol, persisted-format, configuration, dependency, or operational changes, check affected consumers and supported versions. Update relevant docs/examples and describe compatibility, upgrade/rollback limits, and new configuration defaults when they change. New dependencies must solve a current need and fit the workspace's license, toolchain, and feature policy.
-- For hot-path or resource-management changes, check allocation/copying, blocking, unbounded work, and lock duration where affected. Support performance claims with an appropriate measurement or clearly label them as expectations; a benchmark is not required for unrelated changes.
-
-## Behavioral Tests
-
-- For behavior changes, add or update the narrowest test that calls the real implementation and asserts an observable result. Existing tests can provide coverage when they directly exercise the changed behavior; do not duplicate production logic as the test oracle.
-- Cover the changed contract's relevant failure and boundary cases, not only success. A bug regression should fail without the fix; do not broaden assertions or rely only on a successful call when the result or side effect is what matters.
-- Follow `docs/testing/README.md` for test layers, runners, isolation, synchronization, and flaky tests. Use controlled clocks or explicit synchronization for time/concurrency tests instead of fixed sleeps, and keep waits bounded.
-- Report the checks actually run and their outcomes, including skipped or blocked checks and the behavior they leave unverified. Do not describe focused local checks as full CI coverage.

+## Review Protocol
+
+1. Freeze the exact final diff/head (or the design under review) and list the

+2. Run the review shape required by the repository risk tier.
+3. For each selected lens, either report a concrete finding or a null verdict
+   naming the attacks performed.
+4. Apply root `AGENTS.md`'s finding standard. Test each candidate against callers,
+   existing coverage, and invariants before accepting it; an adversarial role
+   does not have to produce a defect.
+5. Fix or rebut supported findings with code-path, test, or invariant evidence.
+6. After a non-trivial edit, rerun only lenses affected by that edit against the
+   new exact diff.
+
+Do not turn a null verdict into a long checklist. Record concise evidence that
+the relevant failure classes were attacked, then stop under the root completion
+rule. Keep the required per-lens verdicts for high-risk PRs.

+# Compatibility Lens

+- Internal metadata uses `metadata_compat` helpers for dual RustFS/MinIO keys,
+  including mixed casing and removal of both twins.
+- Binary UUID metadata treats absent, empty, and nil as no value. Unversioned
+  remote tiers receive no `versionId`; versioned purge requests retain the real
+  version ID.
+- `xl.meta` changes preserve supported header/meta versions, recompute
+  signatures, decode legacy fixtures, and remain readable by old RustFS/MinIO.
+- Foreign/corrupt metadata validates parallel array lengths and missing fields;
+  it returns a decode error rather than indexing, panicking, or fabricating data.
+- Do not “correct” byte-for-byte MinIO ports without legacy fixture evidence.
+  Bitrot framing, shard math, distribution, and inline prefixes are contracts.
+- Client-visible metadata/events strip both internal prefixes
+  case-insensitively.
+- Proto fields are appended, never reused/renumbered; FlatBuffers tables extend
+  compatibly and absent new fields fail closed where authorization/quorum is
+  involved.
+- Replay real client request shapes and exact pagination boundaries for S3
+  handler changes.
+- Bucket metadata/IAM/config parsing remains compatible with pinned real MinIO
+  fixtures and encrypted migration data.
+- Compatibility shims use `RUSTFS_COMPAT_TODO(<task-id>)`, have a removal
+  condition, and default toward reading old data safely.
+
+## Outbound targets
+
+- A change to what the replication or migration client sends by default
+  (checksum policy, payload framing, headers, version-id addressing) is judged
+  against every target class, not the one it fixes. Name each target-side rule
+  the current default satisfies — checksum required with Object Lock

+  MD5 — and show which cell of

+- Secrets/signatures: use constant-time comparison, normalize public failures,

+- RPC: bind signatures to the exact method/path and timestamp; reject replay,
+  stale, malformed, truncated, and invalid-enum payloads without panic.
+- Paths/object/archive entries: reject traversal, absolute/platform escapes,
+  and normalization differences between authz and storage.
+- Copy/multipart/presigned POST: enforce source, destination, version-aware
+  actions, copy-source conditions, and every signed policy condition.
+- Logging/errors: never expose credentials, tokens, expected signatures, raw
+  secret-bearing input, or merged configs—including via `Debug` and parse errors.
+- Untrusted serde: reject unknown fields where compatible and validate
+  security-critical defaults/ranges before numeric conversion.
+- SSE/browser/CORS/trusted proxy: inspect stored ciphertext and wrapper order;
+  isolate user content; never reflect credentialed arbitrary origins or trust
+  forwarded identity from direct clients.
+- Object Lock: unreadable/fabricated/unparsable metadata fails closed across
+  foreground, lifecycle, scanner, and force-delete paths.
+
+Security findings distinguish unauthenticated compromise from a
+low-privileged authenticated bypass.

-## Reconcile main and remove the completed release branch

-1. Compare the exact published tag with current main. Audit every release-side commit since their merge base, including inherited backports. An ahead count is a history difference, not proof of missing changes. Use ancestry and patch equivalence, then inspect current code and regression evidence for squashed, adapted, superseded, or reverted changes. Record each commit as present, superseded, release-only, or missing; a positive `git cherry` result alone does not prove a missing fix.
-2. Bring missing shared changes to main through a reviewed PR and the required checks before closing the follow-up. Preserve main's later changes; decide version bumps and pinned Console configuration separately. If a history merge is needed, use a merge commit and verify the release commit is an ancestor of main; squash does not establish that ancestry. Do not merge main into the published release branch or move its tags. Report unresolved changes instead of claiming reconciliation is complete.
-3. After publication and authorized follow-ups are complete, delete the remote `release/<target>` branch. Immediately before deletion, verify its HEAD still equals the published tag's commit and no open PR targets or originates from it. Preserve a branch with newer work or open PRs and report the blocker. Use a deletion with an expected-old-SHA check to avoid removing a concurrently advanced branch.
-4. Verify the remote branch is absent and the final and preview tags still resolve to their recorded commits. Remove a local release branch only if it is task-owned, unchecked out, and has no unpreserved work.

+description: Perform a dedicated RustFS security/advisory review for authn/authz, IAM, RPC trust, paths, secrets, browser isolation, encryption, Object Lock, or other security boundaries. Use only when the user requests a security/advisory review or an adversarial review explicitly escalates to the full advisory map; do not auto-load solely because code touches a sensitive path.

+
+# RustFS Security Advisory Lessons
+
+Use this skill as the deep security lens. For a normal adversarial review with a
+matched security surface, the concise security reference under
+`adversarial-validation` is sufficient.
+
+## Workflow
+
+1. Freeze the exact diff/head and identify the changed trust boundaries.
+2. Inspect the headings in [advisory-patterns.md](references/advisory-patterns.md),
+   then read the matching sections. Read the full map only for a broad security
+   audit. Useful headings are
+   auth/admin, IAM/STS/OIDC, policy/plugins, S3/copy/multipart, protocols, paths,
+   secrets/logging/RPC, browser/CORS/proxy, SSE, Object Lock, and serde.
+3. Trace unauthenticated, low-privilege, wrong-action/owner/bucket, malformed,
+   and default-config cases. Security decisions must fail closed.
+4. Require a focused negative regression test for the bypass/exploit form, not
+   only the intended success path. State residual risk when a test is impractical.
+5. Report proven vulnerabilities separately from defense-in-depth hardening.
+
+When advisory currentness matters, fetch the live inventory instead of treating
+the reference as a status mirror:
+
+```bash
+gh api repos/rustfs/rustfs/security-advisories --paginate \
+  --jq '.[] | {ghsa_id,state,severity,summary,updated_at}'
+```
+
+Fetch an individual advisory only when the live summary indicates a new or
+changed lesson.
+
+## Finding Standard
+
+Every candidate names the lower-trust principal, the boundary it crosses, the
+affected resource, and the observable result. A best-practice gap or an impact
+confined to the caller's own principal is hardening, not a candidate.
+
+Report each candidate under exactly one verdict:
+
+- `confirmed`: a complete `file:line` source trace and a bounded observed
+  result. Only confirmed findings carry severity; each also states attacker
+  prerequisites, concrete input/path, impact, smallest safe fix, and a
+  regression check.
+- `needs_validation`: the trace is blocked on one exact unresolved fact, such
+  as deployment or infrastructure behavior. State that fact; assign no severity
+  and do not substitute an assumption.
+- `rejected`: a disproved candidate, with the caller, invariant, or test that
+  disproves it.
+
+Do not exaggerate unauthenticated impact when the actual issue requires
+authenticated low privilege.

+
+When current advisory state, severity, URLs, or full text matters, fetch it live:

+
+## Pattern Index
+
+### Admin authorization and route exposure
+
+- `GHSA-pfcq-4gjr-6gjm`: notification target endpoints accepted authenticated users but skipped admin authorization. Lesson: distinguish authn from authz; admin target CRUD must call the operation-specific admin authorization path.
+- `GHSA-mm2q-qcmx-gw4w`: `ListServiceAccount` used `UpdateServiceAccountAdminAction`, while update lacked target ownership checks. Lesson: exact action constants and ownership checks are both required; information disclosure can chain into secret rotation and takeover.
+- `GHSA-vcwh-pff9-64cc`: `ImportIam` checked `ExportIAMAction` for an import/write operation. Lesson: every admin handler must authorize the action it actually performs.
+- `GHSA-jqmc-mg33-v45g` and `GHSA-8784-9m7f-c6p6`: `/profile/cpu` and `/profile/memory` were whitelisted from auth and allowed expensive diagnostics plus path disclosure. Lesson: profiling/debug endpoints need admin auth, opt-in, rate limits, and non-sensitive responses.
+- `GHSA-f5cv-v44x-2xgf`: `/rustfs/admin/v3/metrics` accepted any authenticated IAM user and skipped admin authorization. Lesson: read-only metrics and diagnostic admin endpoints still require an operation-specific admin action check.
+- `GHSA-796f-j7xp-hwf4`: `/rustfs/admin/v3/list-remote-targets` checked only that credentials existed and leaked replication target credentials. Lesson: replication target reads are privileged admin operations, and stored remote credentials require strict authz plus response redaction review.
+- `GHSA-xp32-gxq2-3v52`: console license metadata endpoint was public and exposed subject and expiration fields. Lesson: management metadata endpoints should require admin auth or return only coarse public status.
+
+### IAM import, service accounts, and privilege boundaries
+
+- `GHSA-566f-q62r-wcr8`: `ImportIam` accepted attacker-controlled service account `parent`, `claims`, `accessKey`, and `secretKey`, enabling persistent backdoor accounts under root. Lesson: imported IAM payloads are untrusted data and must be validated against privilege boundaries.
+- `GHSA-3495-h8r9-gfqg`: `ExportIAM` wrote regular-user and service-account secret keys into exported ZIP data. Lesson: IAM export is a credential-disclosure boundary; redact, seal, or strictly justify every exported secret before treating export permission as safe.
+- `GHSA-5354-r3w2-34m8`: `AddServiceAccount` checked `CreateServiceAccountAdminAction` but trusted caller-supplied `target_user`, allowing service accounts under the root parent. Lesson: service-account create paths must validate parent ownership or root/admin authority, not only the create action.
+- `GHSA-xgr5-qc6w-vcg9`: `deny_only=true` skipped allow checks and let restricted service accounts mint unrestricted children. Lesson: deny-only logic must never become implicit allow for privilege creation.
+- `GHSA-mm2q-qcmx-gw4w`: leaked service account access keys plus update-without-ownership formed an escalation chain. Lesson: service-account identifiers are security-sensitive because update APIs consume them.
+
+### STS, OIDC, and federation flows
+
+- `GHSA-5qfg-mf7r-jp3w` and `GHSA-3473-5353-xhwh`: `AssumeRoleWithWebIdentity` was reachable through unauthenticated `POST /` routing and could issue temporary credentials from crafted web identity input. Lesson: every STS route needs explicit SigV4 or trusted identity-provider validation before role assumption, and unauthenticated exemptions must be narrowed to the exact action with uniform failure responses.
+- `GHSA-jxrr-r6pv-h958`: unsigned JWT issuer data was decoded before verification to select an OIDC provider, and distinguishable failures could expose provider configuration. Lesson: web-identity routing may be unauthenticated, but pre-verification claims are untrusted routing hints; bound and rate-limit the request, normalize public errors, and verify signature, issuer, audience, and expiration before issuing credentials.
+- `GHSA-ccrv-v8v9-ch9q`, `GHSA-48rf-7j3q-3hfv`, and `GHSA-xvfh-7c9g-hpw2`: service-account-controlled material could self-sign JWT session tokens with forged policy claims, and missing `exp` was accepted for service-account tokens. Lesson: session tokens must be signed by a trusted issuer/key path, enforce required claims and expiration, and reject self-signed or principal-controlled tokens.
+- `GHSA-9pjf-w3c2-m32r`, `GHSA-4x2q-cpx9-9h26`, and `GHSA-xvpm-p3f7-34c3`: public OIDC authorize/callback flows trusted request `Host` or forwarded scheme when building credential-bearing redirects. Lesson: OIDC redirects must use configured allowlisted origins and trusted-proxy handling; never derive the post-login credential destination from direct client headers.
+- `GHSA-m479-9x88-94w6`, `GHSA-frwq-mfqx-83p8`, `GHSA-q9q8-rf9r-fg9f`, and `GHSA-j5c2-hhf7-6gf5`: OIDC validation accepted attacker-controlled discovery URLs because hostname checks rejected only literal forbidden IPs, allowing DNS rebinding SSRF. Lesson: outbound federation URL validation must resolve and classify hostnames at the connection boundary and reject loopback, private, link-local, and rebound addresses.
+
+### IAM policy conditions and external policy plugins
+
+- `GHSA-6r96-hmgc-726c`: request headers collided with lowercase server-derived condition keys such as `userid`, `groups`, `versionid`, and JWT/LDAP claims. Lesson: never let caller-controlled headers append to or replace server-derived policy context; reserve trusted condition keys and keep intentional request-header keys separate.
+- `GHSA-v9cp-qfw9-9pfp`: quantified negated string conditions applied negation after aggregation, transposing `ForAllValues` and `ForAnyValue` semantics. Lesson: push negation into the per-value predicate for quantified operators and test partially overlapping multi-value sets.
+- `GHSA-5w8r-p896-6vq2`: OPA policy mode skipped `ExistingObjectTag/*` loading, so tagged objects looked untagged to external policies. Lesson: external authorization plugins need the same object-tag and request context as built-in policy evaluation before they decide.
+- `GHSA-9wgh-5r68-49p7`: substituted policy-variable values could recreate `${...}` and loop inside a single resolution pass, never reaching the outer iteration limit. Lesson: bound substitutions within each pass and test cycles formed across otherwise literal resolver values; confirm whether attacker-controlled claims can reach those values before assigning remote impact.
+
+### S3 object actions, copy, multipart, and upload policy validation
+
+- `GHSA-g8w9-qw9q-fghr` and `GHSA-xm99-m3gq-83g8`: a valid presigned `PutObject` accepted extra `x-amz-*` headers omitted from `SignedHeaders`; `x-amz-copy-source` could turn that upload capability into a cross-bucket read performed as the signer. Lesson: a presigned URL is a bounded capability; inspect all received security-sensitive headers and reject unsigned ones before selecting the S3 operation or reaching storage.
+- `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-cg33-pxfp-qcj3` and `GHSA-65wq-gjw8-xr9w`: `HeadObject` and object-tagging paths authorized current-object actions while operating on an explicit historical `versionId`. Lesson: select the corresponding version action for metadata and tag reads and writes too; audit every operation that accepts a version ID.
+- `GHSA-gjph-xcgw-4p7w`: `PutObject` and browser POST accepted a caller-supplied `versionId` and replaced an unlocked historical version with only `s3:PutObject`. Lesson: only replication-authorized writes may choose an existing version ID; ordinary uploads must not rewrite version history.
+- `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`.
+- `GHSA-wfxj-ph3v-7mjf`: `UploadPartCopy` checked source and destination independently but missed destination copy-source policy constraints. Lesson: source read and destination write checks are not sufficient when policy constrains allowed copy sources.
+- `GHSA-w5fh-f8xh-5x3p`: presigned POST accepted uploads without enforcing signed policy conditions. Lesson: parse and enforce all POST policy constraints server-side, including size, key prefix, and content type.
+
+### Protocol frontends and IAM parity
+
+- `GHSA-3g29-xff2-92vp`: FTP `RETR` and `SIZE`/`MDTM` read paths authenticated the user but skipped IAM before calling storage. Lesson: non-HTTP protocol frontends must enforce the same per-operation authorization as the S3 API before backend access.
+- `GHSA-g3vq-vv42-f647`: FTPS `MKD` called `create_bucket` without checking `s3:CreateBucket`. Lesson: protocol command handlers need action-specific checks even when sibling handlers already authorize correctly.
+- `GHSA-3p3x-734c-h5vx`: FTPS and WebDAV compared secret keys with early-return string equality, while FTPS also returned distinguishable invalid-user and invalid-password failures. Lesson: password-style protocol auth needs constant-time secret comparison, indistinguishable failures where practical, and rate limiting.
+- `GHSA-rhg6-jrf2-29c4`: WebDAV, FTP/FTPS, and SFTP used identity-policy checks with empty conditions and bypassed S3 bucket-policy explicit denies and condition-key denies. Lesson: alternate listeners must evaluate the same effective policy and trustworthy request context before storage access.
+
+### Filesystem paths and object key traversal
+
+- `GHSA-pq29-69jg-9mxc`: RPC `read_file_stream` joined untrusted paths under a volume directory without canonical boundary checks. Lesson: `PathBuf::join` plus length checks are not path security.
+- `GHSA-8r6f-hmq2-28rg`: object keys containing traversal sequences bypassed bucket/object authorization when mapped to filesystem paths. Lesson: reject traversal at object-key parsing and verify final storage paths remain under the expected bucket/key root.
+- `GHSA-f4vq-9ffr-m8m3`: Snowball auto-extract accepted archive entries such as `../victim-bucket/object`, authorized the raw attacker-bucket path, then storage path cleaning crossed bucket boundaries. Lesson: archive entries become object keys and need traversal rejection plus consistent authz/storage normalization before writes.
+- `GHSA-g7fq-6xjm-mxf4`: versioned `DeleteObjects` accepted dot-segment keys, authorized the literal prefix, then wrote delete markers under a resolved sibling prefix. Lesson: validate each batch key before authorization and storage normalization, using the same object-name rules as single delete.
+
+### Secrets, defaults, and cryptographic misuse
+
+- `GHSA-j59h-h7q5-q348`, `GHSA-3wm5-wpm5-hmfm`, `GHSA-6wc8-xm48-qhmx`, `GHSA-9gf3-jx4p-4xxf`, `GHSA-63xc-c3w3-m2cf`, and `GHSA-ch63-6q4v-hwp5`: RustFS shipped known default root credentials that could authenticate to S3, admin APIs, IAM, KMS, console, and token-signing surfaces. Lesson: root credentials must be operator-provided or generated per install; known defaults and warnings are not acceptable for network-reachable deployments.
+- `GHSA-h956-rh7x-ppgj`: gRPC used the hard-coded token `rustfs rpc` on both client and server. Lesson: source-visible shared tokens are authentication bypasses.
+- `GHSA-r5qv-rc46-hv8q`: internode RPC HMAC secret fell back to the public default `rustfsadmin`. Lesson: RPC/internode auth must fail closed instead of silently using public defaults.
+- `GHSA-75fx-qg6f-8rm7` and `GHSA-68cw-96m3-h2cf`: internode RPC secrets were derivable from known root credentials, making raw storage RPC signatures forgeable when explicit RPC secrets were unset. Lesson: RPC auth keys must be independent random secrets, never derived from S3 root credentials, and raw storage RPC should not share the public S3 listener without an internode-only boundary.
+- `GHSA-m77q-r63m-pj89`: STS JWTs used the root secret key as the shared token signing key, allowing token forgery when the root secret was known. Lesson: STS signing keys need key separation, rotation, and key IDs; do not reuse root credentials for JWT/HMAC signing.
+- `GHSA-923g-jp7v-f97f`: license verification embedded a production RSA private key and used private-key decryption as authenticity. Lesson: ship verifying/public keys only and use real signature verification.
+
+### Sensitive logging and debug output
+
+- `GHSA-r54g-49rx-98cr`: STS credentials were logged at info level. Lesson: generated credentials must never be logged in plaintext.
+- `GHSA-8cm2-h255-v749`: debug logs leaked session tokens, secret keys, JWT claims, and raw STS response bodies. Lesson: redaction must cover custom `Debug` implementations and dependency response-body logging.
+- `GHSA-333v-68xh-8mmq`: invalid RPC signature logging included the shared HMAC secret and expected signature. Lesson: error paths often leak secrets; never log raw secrets or derived authenticators.
+
+### RPC input validation and panic safety
+
+- `GHSA-gw2x-q739-qhcr`: malformed gRPC `GetMetrics` payloads reached `unwrap()` on deserialization and caused remote DoS. Lesson: every network/RPC deserialization failure returns an error, not a panic.
+- `GHSA-h956-rh7x-ppgj` and `GHSA-r5qv-rc46-hv8q`: weak RPC auth increased reachability of otherwise internal handlers. Lesson: panic bugs become more severe when internode auth is weak or defaulted.
+- `GHSA-c667-rgrv-99vj`: NodeService authentication signed the service prefix instead of the concrete generated method path, so valid metadata for one RPC could be replayed to another method during the timestamp window. Lesson: RPC HMAC payloads must bind exact gRPC method path, HTTP method surrogate, timestamp, and secret.
+
+### Browser, CORS, and console isolation
+
+- `GHSA-v9fg-3cr2-277j`: object preview rendered attacker-controlled HTML in a same-origin iframe, exposing console credentials stored in `localStorage`. Lesson: user content must be origin-isolated from the console and protected with `nosniff`, CSP, and strict content-type handling.
+- `GHSA-7gcx-wg4x-q9x6`: an incomplete preview fix reintroduced extension-based PDF detection and bypassed the sandboxed fallback for attacker-controlled content. Lesson: browser-surface fixes need regression tests for alternate viewers and file-type branches, and preview trust must come from validated content type plus sandboxing rather than object names.
+- `GHSA-x5xv-223c-8vm7`: default CORS reflected arbitrary origins with credentials. Lesson: never combine reflected origins with `Access-Control-Allow-Credentials: true`; default should be fail-closed.
+
+### Trusted proxy and source IP conditions
+
+- `GHSA-fc6g-2gcp-2qrq`: `aws:SourceIp` trusted client-supplied `X-Forwarded-For` or `X-Real-IP`. Lesson: forwarded IP headers are valid only behind configured trusted proxies; direct clients use socket peer IP.
+
+### SSE and on-disk storage invariants
+
+- `GHSA-xrrf-67jm-3c2r`: SSE metadata reported encryption while reader composition bypassed `EncryptReader` and stored plaintext. Lesson: test actual bytes on disk and wrapper order, not only API metadata.
+- `GHSA-wqmc-vjgv-jrpw`: SSE-C persisted and listed the plaintext MD5 as the ETag, allowing list-only users to confirm or brute-force low-entropy content and correlate equal plaintext across keys. Lesson: encrypted-object ETags must not expose deterministic plaintext fingerprints; protect them with per-object key material and keep listing, conditional, copy, and multipart semantics consistent.
+
+### Object Lock and retention invariants
+
+- `GHSA-j548-9grx-fh4f`: Object Lock enforcement treated unreadable, fabricated, or unparsable bucket metadata as absent configuration and allowed retained objects to be deleted or expired. Lesson: retention must fail closed unless Object Lock absence is authoritative, and every delete, lifecycle, scanner, force-delete, and default-retention path needs the same state distinction.
+- `GHSA-28w4-rp2p-636w` and `GHSA-c7hx-vr97-45rg`: an authorized `DeleteBucket` with `x-rustfs-force-delete: true` removed active COMPLIANCE-retained versions even though ordinary version deletion was denied. Lesson: bucket force-delete must enforce retention across every version, including against root/owner callers.
+- `GHSA-q23w-fp7p-472v`: `PutObjectRetention` policy conditions read `x-amz-object-lock-*` headers while the handler applied mode and date from the XML body. Lesson: authorize the parsed retention that will be stored, or reject mismatched header/body values; compare retention dates as instants so offsets cannot change the applied bound.
+
+### Serde deserialization and input validation
+
+- 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()` 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.

+## Minimum Regression Test Expectations
+
+- Authz fixes: include unauthenticated, valid low-privilege, wrong-action, correct-action, owner, non-owner, and root/admin cases as applicable.
+- Protocol frontend authz fixes: include denied `RETR`, `SIZE`/`MDTM`, `MKD`, bucket probe, and sibling allowed-operation cases; test bucket-policy explicit denies and condition-key denies on each enabled listener against an S3 control, and assert denied paths do not reach storage.
+- IAM fixes: include import/update/list service-account cases with attacker-controlled parent, claims, access key, secret key, and policy.
+- Copy/upload fixes: include cross-bucket, cross-user, source-denied, destination-denied, copy-source-condition, and multipart completion cases.
+- Presigned upload fixes: include a valid presign with extra unsigned tagging, redirect, storage-class, and cross-bucket copy-source headers; require rejection before source or destination storage access, and verify explicitly signed equivalents still work.
+- Version-action fixes: include historical UUID, explicit current version, `null`, range, partNumber, presigned, STS/session, service-account, anonymous bucket-policy, copy source, multipart-copy source, `HeadObject`, and tag read/write cases.
+- Version-write fixes: a `PutObject`-only principal must not replace an existing version through `PutObject` or browser POST `?versionId=`; verify replication-authorized writes and versioned, suspended, and unversioned buckets separately.
+- Policy-condition fixes: include reserved-key header collisions, missing keys, partially overlapping multi-value sets, cyclic variable substitutions, plugin mode, and built-in policy mode.
+- Path fixes: include encoded traversal, absolute path, nested traversal, archive entries with `..`, valid object keys that resemble traversal text but should be rejected, and canonical bucket/prefix boundary checks; test per-key `DeleteObjects` errors and prefix-scoped denials on versioned buckets.
+- Logging fixes: assert redacted output for structs and response bodies that may contain credentials.
+- IAM export fixes: assert exported archives omit plaintext user and service-account secrets unless the format deliberately encrypts or seals them.
+- RPC auth fixes: include captured metadata replay across two concrete methods, stale timestamps, wrong path, wrong method surrogate, wrong secret, and valid same-method calls.
+- Browser/CORS fixes: assert no credentials on reflected/default origins, correct behavior for explicit allowlists, and no same-origin script execution for previewed object content.
+- SSE fixes: inspect stored bytes and verify API metadata, read-back behavior, and on-disk ciphertext together; for ETags, upload equal plaintext under different keys and assert list-only callers cannot derive or correlate the plaintext digest, including multipart objects.
+- Object Lock fixes: include unreadable metadata, fabricated metadata defaults, unparsable config, confirmed absent config, COMPLIANCE/GOVERNANCE retention, lifecycle expiry, scanner sweeps, and force-delete paths; an authorized force-delete must preserve active COMPLIANCE versions. For `PutObjectRetention`, test conflicting header/body values and offset dates against policy bounds and read-back retention.

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

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

 - Every `shared-key` has exactly one writer. `cache-warm.yml` owns `ci-dev`, `ci-feat-rio`, `ci-feat-proto` and `ci-uring`; every other `./.github/actions/setup` call states `cache-save-if` explicitly, and `scripts/security/check_cache_save_if.sh` fails the build when one does not.
 - All readers of a key run on the same image as its writer. Keys that live on hosted runners say so in their name (`ci-uring` is warmed on `ubuntu-latest`; `ci-e2e-distributed-hosted`, `e2e-upgrade-server-hosted`, `e2e-upgrade-tests-hosted`).
-- Moving a job between pools therefore means renaming its key. The new key is empty until a run from `main` (a scheduled run, or a manual dispatch of that workflow from `main`) saves it; until then that lane does a cold build.

-## Delivery Contract
-
-- Establish the requested outcome, affected boundaries, and observable acceptance criteria before editing. For substantial work, keep a short plan with verification points; a small local edit does not need a formal plan or new document.
-- Preserve correctness, security, durability, compatibility, and user-owned work. Within those boundaries, choose the reasoning process, algorithm, and tools; only real dependencies and explicit approval/acceptance gates constrain execution order.
-- Choose the simplest design that satisfies the actual contract. Explore alternatives or restructure in-scope code when evidence justifies it; minimum diff size is not a reason to keep a defective design. Avoid speculative features and unrelated cleanup.
-- Complete the authorized work, verify the final result, and report material limits honestly. Distinguish implemented, locally verified, CI-passed, published, and merged states; never substitute one for another.
 
 ## Operating Model
 
-- Inquiry, diagnosis, review, and planning tasks are read-only unless the user explicitly requests changes.

 ## Task-Specific Guidance
 
 Read only the reference needed for the current task, once per unchanged context:

-### Tooling, Build, and CI Changes
-
-- Run the changed language's validator and the narrowest test of the actual entry point, including failure behavior. For workflow edits, follow `.github/AGENTS.md`; a documentation-only tier does not cover executable scripts or build settings.

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

 ### Security
 
 - **Header-signed SigV4 requests honour only signed headers** (GHSA-xm99-m3gq-83g8): a request authenticated with a SigV4 `Authorization` header that carries an `x-amz-*` request header not listed in its `SignedHeaders` is now rejected with `403 AccessDenied` ("There were headers present in the request which were not signed"), matching AWS S3 and the presigned rule from GHSA-g8w9-qw9q-fghr. Previously anyone holding one header-signed `PutObject` request could add an unsigned `x-amz-copy-source` and turn it into a `CopyObject` that ran with the signer's permissions, copying any object the signer could read into the target. An `Authorization` header whose algorithm token is not `AWS4-HMAC-SHA256` is now rejected instead of being verified as SigV4. The request-envelope headers `x-amz-content-sha256`, `x-amz-decoded-content-length`, `x-amz-trailer` and `x-amz-checksum-algorithm` (the same set the upstream `s3s` fix exempts) and `x-amz-cf-id` (CloudFront) remain tolerated unsigned; AWS SDKs and RustFS's own signers already sign every other `x-amz-*` header. SigV2, JWT and anonymous requests are unchanged.

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

 #### What `make pre-commit` and `make pre-pr` actually run
 
-`make pre-commit` is the **fast** gate: formatting, repository guards, and quick workspace compilation. The exact dependencies of each target are maintained in [`.config/make/pre-commit.mak`](.config/make/pre-commit.mak).
+`make pre-commit` is the **fast** gate. It runs, in order
+(see `.config/make/pre-commit.mak`):
 
-**`make pre-commit` does not replace the scoped Clippy and behavioral test checks applicable to a change.**
+1. `fmt-check` — `cargo fmt --all --check`
+2. `unsafe-code-check` — `./scripts/check_unsafe_code_allowances.sh`
+3. `architecture-migration-check` — `./scripts/check_architecture_migration_rules.sh`
+4. `logging-guardrails-check` — `./scripts/check_logging_guardrails.sh`
+5. `tokio-io-uring-check` — `./scripts/check_no_tokio_io_uring.sh`
+6. `extension-schema-check` — `./scripts/check_extension_schema_boundaries.sh`
+7. `doc-paths-check` — `./scripts/check_doc_paths.sh`
+8. `quick-check` — `cargo check --workspace --exclude e2e_test`
 
-`make pre-pr` is the broader local gate: formatting, shared and additional repository guards, `clippy-check`, and `test` (script tests, workspace tests excluding `e2e_test`, and doc tests). Select it only under the root verification policy. It does not reproduce every CI feature/platform/integration lane; CI still runs its configured repository gates.
+**`make pre-commit` does NOT run clippy and does NOT run any tests.**
+It does not replace the scoped Clippy and test checks applicable to a change.
+
+`make pre-pr` is the **full** gate: it runs all of the guard checks above,
+then `clippy-check` (`cargo clippy --all-targets --all-features -- -D warnings`)
+and `test` (shell script tests, workspace tests excluding `e2e_test`, and doc
+tests). Complete the applicable multi-role adversarial review described in
+`AGENTS.md` first. Do not run `make pre-pr` locally by default before opening or
+updating a pull request. Consider it only for a broad change that spans multiple
+modules and whose impact cannot be bounded by targeted checks; decide from the
+affected boundaries and risks. CI still runs its configured repository gates.

+
+**All Pull Request titles and descriptions MUST be written in English.**
+
+This ensures:
+- Consistency across all contributions
+- Accessibility for international contributors
+- Better integration with automated tools and CI/CD systems
+- Clear communication in a globally understood language
+
+#### PR Description Requirements
+
+When creating a Pull Request, ensure:
+
+1. **Title**: Use English and follow Conventional Commits format (e.g., `fix: improve s3-tests readiness detection`)
+2. **Description**: Write in English, following the PR template format
+3. **Code Comments**: Must be in English (as per coding standards)
+4. **Commit Messages**: Must be in English (as per commit guidelines)
+
+#### PR Template
+
+Always use the PR template (`.github/pull_request_template.md`) and fill in all sections:
+- Type of Change
+- Related Issues
+- Summary of Changes
+- Checklist
+- Impact
+- Additional Notes
+
+**Note**: While you may communicate with reviewers in Chinese during discussions, the PR itself (title, description, and all formal documentation) must be in English.

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

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

 ## Testing
 
 - Keep unit tests close to the module they test.
 - Keep integration tests under each crate's `tests/` directory.
-- Add or update regression tests when existing tests do not directly cover the changed behavior; a bug regression should fail without the fix.

 ## S3 API environment variables
 
 - `RUSTFS_API_OBJECT_MAX_VERSIONS` caps the number of retained versions for a single object. It defaults to `9223372036854775807`, matching MinIO's practical-unlimited default. Set a positive integer to enforce a lower per-object metadata bound.
-- `RUSTFS_VEEAM_SOSAPI_ENABLE` serves Veeam SOSAPI `system.xml` and `capacity.xml` for an authenticated GET or HEAD of those exact bucket-root keys. It defaults to `true`. Explicit version reads use the normal object path. Capacity requests return `ServiceUnavailable` until the scanner publishes a complete snapshot certified for the current bucket incarnation and authoritative quota metadata can be read. Legacy or mixed-version snapshots without an incarnation proof cannot serve capacity until a compatible scanner publishes a certified snapshot. Capacity also returns `ServiceUnavailable` when cluster or disk observations are missing, stale, or degraded. Retry after scanner convergence and storage or metadata recovery. Capacity assumes shard paths have independent backing space; shared physical storage can make the estimate optimistic. Set the flag to `false` to restore the normal object path, including deletion of a real object previously stored at that key.
 - `MINIO_API_OBJECT_MAX_VERSIONS` is accepted as a compatibility alias when the canonical RustFS variable is not set.
