-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.

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

+- Every new control-flow branch needs a concrete triggering input/state. For decoded or peer data, corruption and mixed-version input are valid triggers.
-  helper is better than forced reuse with different semantics.
+- Required values must return a typed error when absent or corrupt; do not use a default that converts corruption into a plausible result.
- Validate untrusted input at its trust boundary, then trust the validated type.
+- Attach error context once where it is actionable. Do not erase typed errors below aggregation or quorum layers.
  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.

  data, corruption and mixed-version input are valid triggers.
 - Required values must return a typed error when absent or corrupt; do not use a
  default that converts corruption into a plausible result.
 - Attach error context once where it is actionable. Do not erase typed errors
  below aggregation or quorum layers.
 ## Rust Boundaries
- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees.
+- Production `unwrap`/`expect` must follow a type guarantee or checked invariant; explain only non-obvious guarantees. Stricter scoped prohibitions, including `crates/AGENTS.md`, still apply. Invalid client, disk, or peer data must return errors rather than trigger panics.
 - Public APIs do not return `Result<_, String>`. Library APIs use domain errors unless intentional erasure is part of the boundary contract; expose a stored inner error through `Error::source()`.
 - Numeric conversions must not silently truncate. Use fallible conversions for untrusted values; validate finiteness, sign, and range before float-to-integer conversion. Clamp/saturate only when required by the domain.
 - Do not add crate-root `#![allow(dead_code)]`.

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

 # RustFS Adversarial Validation
 Use the [repository risk tiers and review shape](../../references/adversarial-validation.md). This skill
 routes a review to RustFS-specific probes without loading unrelated domains.
 ## Select Lenses
 Read only the references required by the diff:
 | Lens | When to read |
 |---|---|
 | [Correctness](references/correctness.md) | Every non-exempt adversarial review |
 | [Simplicity](references/simplicity.md) | Mechanical/standard changes and production growth |
 | [Test coverage](references/test-coverage.md) | Behavior or test changes |
 | [Security](references/security.md) | Authn/authz, IAM, RPC trust, paths, secrets, parsing, browser, encryption |
 | [Concurrency/durability](references/concurrency-durability.md) | Async shared state, locks, storage commit, cancellation, persisted queues |
 | [Compatibility](references/compatibility.md) | S3 surface, MinIO interop, metadata, wire/disk formats, mixed versions |
 | [Performance](references/performance.md) | Request/object hot paths, allocation, blocking work, fsync, fan-out |
 Do not read all references as a precaution. A path name alone is insufficient;
 the changed behavior must touch the lens's domain.
 For a dedicated security audit or advisory analysis, use
 `security-advisory-lessons` instead of loading it automatically during every
 adversarial review.
 ## Review Protocol
 1. Freeze the exact final diff/head (or the design under review) and list the
   selected lenses.
 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
  parameters, `aws-chunked` decoding, version-id adoption, ETag equals content
  MD5 — and show which cell of
  `crates/e2e_test/src/replication_target_matrix_test.rs` covers each.
 - A test that asserts the fix ("no trailer header") is not evidence; the
  matrix cell that asserts the target accepted and stored the object is.
 - Every new environment escape hatch appears in
  `docs/operations/replication-outbound-transport.md` in the same diff.

 # Concurrency and Durability Lens
 - For every changed lock, enumerate overlapping lock sets and construct the
  ABBA interleaving. Multiple-lock order must be documented and consistent.
 - Mark guard lifetimes and every `.await`, disk,
  and RPC call; estimate contention/timeouts. Tokio read/write guards across
  `.await` need bounded hold time; long-lived reads can wedge writers (#4195).
  Keep `std::sync::Mutex` holds brief and never across `.await`.
 - Use direct `fetch_*` for unconditional atomic read-modify-write and
  `compare_exchange` for conditional updates.
 - Object commits remain fenced if the distributed lock is lost after shard
  writes and before metadata rename.
 - For write/rename changes, trace `write tmp -> sync tmp -> rename -> sync parent
  -> sync required ancestors`; simulate a crash after each step and honor the
  configured durability gate.
 - Multi-disk fan-out counts every result. Quorum-minus-one cannot become success;
  heal remains best-effort per target where that is the established contract.
 - At every new cancellable await between mutation and cleanup/commit, drop the
  future and inspect leftover files, counters, permits, and replay state.
 - Multipart operations on the same upload ID are serialized where required;
  abort/complete/list races cannot delete parts before durable commit.
 - Post-commit cleanup is best-effort, retry-safe, and cannot fail an already
  committed write or delete the last surviving copy.
 - Persisted read-modify-write uses serialization/CAS. Queue replay is crash-safe
  and duplicate delivery has an idempotency contract.
 - Streaming reconstruction failures after partial output surface as errors, not
  successful EOF.

 # Correctness Lens
 Attack the changed behavior, not every subsystem in the repository.
 - Trace new error paths to the caller. Inject the ignored/wildcard variants and
  verify they cannot become success, not-found, or a plausible default.
 - Exercise zero/empty/missing, maximum, and exact-boundary inputs for every
  changed count, size, index, page limit, or optional value.
 - For aggregation/quorum changes, test exactly quorum and quorum-minus-one with
  mixed disk errors and nil/placeholder entries.
 - For listing/pagination, test `n == max`, `n == max + 1`, delimiter folding,
  continuation markers, and object/prefix name collisions.
 - For EC/read/streaming changes, inject failure after partial output and verify
  the client receives an error rather than a clean truncated body. Assert exact
  bytes and length.
 - For multipart/object commits, fail before/after rename and cleanup; committed
  data must remain readable and pre-commit cleanup must not destroy parts.
 - Bound recursion over untrusted or persisted input; handle corrupted/cyclic
  tree and cache traversals safely.
 - For version/index ordering, test `len - 1`, `len`, equal timestamps, missing
  versions, and deterministic tie-breaking.
 - For directory-object behavior, trace `__XLDIR__` at the store layer; branches
  below the layer that sees trailing slashes are dead.
 - For binary UUID metadata, absent, empty, and nil all mean no value. Never send
  nil/empty `versionId` to an unversioned tier.
 - For agent rules/skill routers, test a trigger matrix covering ordinary
  inquiry, low-risk implementation, explicit review, high-risk code, PR
  creation, release, and post-PR monitoring. Each case must select only the
  intended workflow and retain required safety/authorization boundaries.

 # Performance Lens
 - For added clones/allocations on request/object/block paths, quantify copied
  data and frequency. Recommend borrowing, move, `Bytes`/`Arc`, `Cow`, or
  capacity reservation only for a concrete repeated cost.
 - Route every new sync/flush through the durability-mode and bucket override
  gates; mode `none` must not pay the new fsync.
 - Keep blocking filesystem/CPU work off async runtime threads, but do not split
  one small operation into many `spawn_blocking` round trips.
 - Measure lock hold time across I/O and compare acquisition order for ABBA.
 - Keep cleanup, extra stat/rename, and diagnostics out of the PUT commit critical
  section when they need not be there.
 - Detect per-item serial I/O/RPC in batch APIs and accidental quadratic scans;
  use a gate or bounded concurrency when the concrete fan-out warrants it.
 - Count buffer growth and byte copies in EC/bitrot paths; preserve pool gauge
  balance and avoid repeated metadata decode/fetch per object.
 - Repetitive success logs stay at `trace`; metrics/instrumentation on hot paths

 Use `security-advisory-lessons` only for a dedicated advisory/security audit.
 For an ordinary matched diff, attack these boundaries:
 - Admin routes: route registration, whitelist, handler authn, and the exact
  `AdminAction` must agree. Read-only diagnostics still require admin authz.
 - IAM/service accounts: treat parent, claims, keys, groups, status, and policy
  names as attacker-controlled; prove ownership/root authority before writes.
 - Protocol frontends: every changed/sibling command authorizes the matching S3
  action before reaching storage.
 - Secrets/signatures: use constant-time comparison, normalize public failures,
  keep RPC/root/STS keys independent, and fail closed when secrets are absent.
 - 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.

 # Simplicity Lens
 - Compare the production diff with the smallest equivalent local edit. Fewer
  lines alone are not evidence; the replacement must preserve correctness,
  compatibility, readability, and real boundaries.
 - Search the touched crate, domain owner, `crates/utils`, `crates/common`, and
  relevant dependencies for each new helper, constant, wrapper, or fixture.
 - Reject forced reuse when normalization, error, deadline, or durability
  semantics differ.
 - Require a concrete trigger for every new defensive branch. Keep boundary
  checks for disk/RPC/version data and checks immediately before destructive
  actions.
 - Flag one-caller helpers only when they merely forward or split a short linear
  flow without adding domain naming, invariant isolation, or useful context.
 - Ensure a replacement removes the superseded in-scope path or keeps one
  canonical core behind a documented compatibility adapter.
 - Remove narration/change-history comments; preserve concise safety, lock,
  durability, and compatibility invariants.
 - Treat tests, fixtures, generated code, and documentation separately from
  production growth. Do not optimize away meaningful regression coverage.
 A finding must include a concrete smaller design, not a style preference.

 # Test-Coverage Lens
 - For every behavior claim, name the focused test/check that fails if the
  changed hunk is reverted. If none is practical, require the reason and
  residual risk.
 - Confirm tests exercise the real production path and distinguish the intended
  behavior from the named regression. A success, `is_err()`, or no-panic check
  can be sufficient when that is the actual contract; require exact values,
  bytes, state, or error variants when those distinctions matter to the change.
 - For new flags/modes, verify each branch and ask which test fails if the branch
  is inverted.
 - For new error propagation, inject the failure and assert the caller observes
  it; mentally replacing `?`/`return Err` with success must break a test.
 - Streaming GET tests assert the complete body and length under degraded reads.
 - Disk/wire-format tests use pinned foreign/legacy fixtures; same-code
  round-trips are insufficient for compatibility.
 - Concurrency tests use readiness polling, isolate global state, and avoid fixed
  sleeps or unrealistically short timeouts. Use nextest groups when process-level
  serialization is required.
 - Internal metadata tests assert both RustFS and MinIO keys, not only read-back
  through a helper that prefers one key.
 - Avoid duplicate tests of the same production path and poison-value class.
  Boundary companions are distinct coverage: `n == max` vs `max + 1`, and
  absent vs empty vs nil UUID.

 ## 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.

 # 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.

 # RustFS Advisory Pattern Map
 This file is a lesson map, not an advisory inventory mirror. It keeps durable security patterns distilled from RustFS GitHub Security Advisories.
 When current advisory state, severity, URLs, or full text matters, fetch it live:
 ```bash
 gh api repos/rustfs/rustfs/security-advisories --paginate \
  --jq '.[] | {ghsa_id,state,severity,summary,updated_at}'
 gh api repos/rustfs/rustfs/security-advisories/<GHSA_ID>
 ```
 Update this file only when an advisory adds or changes a reusable lesson, affected surface, validation pattern, or regression-test expectation. Do not update it for state-only, URL-only, count-only, or timestamp-only changes.
 ## 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.

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

 - 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. The `build.yml` aarch64 release legs append `-ubicloud-arm` for this reason. `cache-warm.yml` does not write those keys.
 - `CARGO_BUILD_JOBS` and every other `CARGO*`, `CC*`, `CFLAGS*`, `CXX*`, `CMAKE*` and `RUST*` variable is hashed into the key. `ci.yml` sets `CARGO_BUILD_JOBS` at step level for that reason; promoting it to job level rotates the key for every lane that shares it.

 # Warp A/B budget gate for the hotpath series (rustfs/backlog#935 HP-14, item 4).
 #
 # Two entry points, honestly scoped:
 #   * schedule (nightly, on main): post-merge detection — catches a regression
 #     within 24h of landing, not before merge.
 #   * workflow_dispatch: an explicitly selected trusted ref.
 # The dispatch input can run the gate with --allow-regression so a deliberate
 # correctness cost (e.g. the #4221 fsync durability fix) is recorded, not
 # blocked (rustfs/backlog#935 correction 1).

 ## 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.

 ## [Unreleased]
 ### Deployment
 - Existing volumes created by older root-running container images must be writable by the non-root runtime identity before upgrading. The default container UID/GID is `10001:10001`; stop the affected instances, verify host mount paths, and for ordinary bind mounts run `sudo chown -R 10001:10001 /actual/data /actual/logs` on each RustFS data/log mount. Account for ACLs, NFS, Kubernetes, and rootless UID mappings. Image-build ownership changes do not migrate mounted data. See the Docker Quick Start in [README.md](README.md).
 - Local disk initialization now checks file creation, writing, and deletion in the data root and fixed internal metadata directories. Unwritable disks are rejected using existing startup/quorum rules, with filesystem errors and Unix runtime/owner IDs logged for permission failures, instead of admitting those disks and discovering the mismatch on a later write. Existing object trees are not scanned and volume ownership is never changed automatically.
 ### 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
-**MANDATORY**: All code must be properly formatted before committing. This project enforces strict formatting standards to maintain code consistency and readability.
+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).
 #### Verification Requirements
-Before submitting your changes for review, you **MUST**:
+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.
-1. **Format your code**:
+- For Rust changes, format with the repository configuration and verify with `cargo fmt --all --check`. Inspect formatter edits and keep unrelated work out of the change.
-
+- For Rust behavior changes, run focused behavioral tests and package-scoped Clippy with the affected targets/features and `-- -D warnings`. Compilation alone does not check lint policy, and a test filter matching zero tests does not verify behavior.
-   ```bash
+- 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.
-   cargo fmt --all
+- Complete applicable CI gates before merge. Local scope selection does not waive CI requirements or permit weakening a gate.
   ```
 2. **Verify formatting**:
   ```bash
   cargo fmt --all --check
   ```
 3. **Pass clippy checks**:
   ```bash
   cargo clippy --all-targets --all-features -- -D warnings
   ```

   ```bash
   cargo check --all-targets

 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.

- 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.
+- Preserve error variants callers need for recovery, aggregation, or quorum decisions. Use type-erased errors only when erasure is intentional in the boundary contract, not as a shortcut around error design.
- When implementing `std::error::Error`, always override `fn source()` if you store an inner error. Breaking the error chain makes debugging impossible.
+- When implementing `std::error::Error`, expose a stored inner error through `source()` so the error chain remains available.
 - Internal helpers that return `Result<_, String>` and are immediately wrapped via `.map_err(Error::other)` should return the actual error type directly.
 ## Concurrency
 - Document lock acquisition order when a module uses multiple locks. Never acquire the same set of locks in different orders across code paths.

 ## 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.
