+description: Prepare a RustFS release branch like PR #2957 by bumping versioned files, aligning release assets, running required verification, and finishing with commit, push, and gh PR creation. Use when publishing a new RustFS alpha, beta, or stable release.
+---
+
+# RustFS Release Version Bump
+
+Use this skill when the task is to prepare a new RustFS version release branch following the pattern validated in PR `#2957`.
+
+## Read first
+
+- Read `AGENTS.md`.
+- Read `.github/pull_request_template.md`.
+- Inspect the current branch diff against `origin/main`.
+- Do not assume every release file should change in the same way every time.
+
+## Scope validated by PR #2957
+
+The `1.0.0-beta.3` release branch updated these files:
+
+- `Cargo.toml`
+- `Cargo.lock`
+- `README.md`
+- `README_ZH.md`
+- `flake.nix`
+- `helm/rustfs/Chart.yaml`
+- `rustfs.spec`
+
+Treat this file list as the default checklist for future release bumps. Only drop a file if the repository's current release pattern clearly says it is no longer part of the publish flow.
+
+## Workflow
+
+1. Confirm release intent
+- Identify the target version string exactly, for example `1.0.0-beta.4`.
+- Check whether the user wants only local commit preparation or the full `commit + push + PR` flow.
+- Compare the branch against `origin/main` and isolate only release-related edits.
+- If the target version is not explicit, stop and ask for it before editing.
+
+2. Update core Rust workspace versions
+- Bump the workspace version in `Cargo.toml`.
+- Bump all internal workspace crate versions in `Cargo.toml`.
+- Ensure `Cargo.lock` reflects the same release version for workspace packages.
+- Re-read the diff and verify there are no partial version leftovers.
+
+3. Align release assets
+- Update versioned Docker examples in `README.md` and `README_ZH.md` using the `<version>` tag form, for example `rustfs/rustfs:1.0.0-beta.4`.
+- Update `flake.nix` package version.
+- Update `helm/rustfs/Chart.yaml` `appVersion`.
+- Update `helm/rustfs/Chart.yaml` `version` using the release-chart rule:
+- `1.0.0-beta.3` -> `0.3.0`
+- `1.0.0-beta.4` -> `0.4.0`
+- Follow the same pattern for later beta releases unless the repository rule changes.
+- Update `rustfs.spec` release metadata and changelog entry.
+- Set `rustfs.spec` `Release` to the prerelease suffix without the base version, for example `beta.3` for `1.0.0-beta.3`.
+- Keep the release asset changes in a separate commit from the core Rust workspace version bump when the branch contains both.
+
+4. Stop and discuss before changing release policy
+- Ask before changing the established Docker tag style away from `<version>`.
+- Ask before changing the established Helm chart version mapping away from `beta.N -> 0.N.0`.
+- Ask before changing the established `rustfs.spec` `Release` rule away from the release suffix form such as `beta.N`.
+- Ask before widening the release scope beyond the files already validated in PR `#2957`.
+
+5. Verify before shipping
+- Run `make pre-commit`.
+- If verification succeeds, run `cargo clean` to remove generated build artifacts before wrapping up.
+- If `make pre-commit` fails, stop and return `BLOCKED`.
+
+6. Commit structure
+- Prefer two commits when the change naturally splits:
+- `chore(release): prepare <version>` for `Cargo.toml` and `Cargo.lock`
+- `chore(release): align release assets for <version>` for docs and packaging metadata
+- If the user asks for a single commit, follow that request.
+
+7. Push and PR
+- Push the release branch with `git push -u origin <branch>` or `git push` if upstream already exists.
+- Create the PR with `gh pr create --base main --head <branch> --title ... --body-file ...`.
+- Keep the PR title and body in English.
+- Keep the `.github/pull_request_template.md` headings exactly.
+
+## Ready-to-check commands
+
+- `git diff --name-only origin/main...HEAD`
+- `git diff --stat origin/main...HEAD`
+- `make pre-commit`
+- `cargo clean`
+- `git status --short --branch`
+
+## Output expectations
+
+When using this skill, return:
+
+- The files changed for the release bump
+- Any uncertainty that needs user confirmation before editing
+- Verification status
+- Commit messages used
+- Push status and PR URL when the GitHub flow was requested
+
+## Established release policy
+
+- Docs use Docker tags in `<version>` form, not `v<version>`.
+- `helm/rustfs/Chart.yaml` `version` follows `beta.N -> 0.N.0` based on the current release policy.
+- `rustfs.spec` `Release` follows the release suffix form, for example `beta.3`.
+- If any of these rules need to change in the future, pause and confirm before editing.

+description: Apply RustFS security lessons distilled from repository GitHub Security Advisories. Use when making or reviewing RustFS code changes, doing security checks, handling PR review for auth/authz, IAM, storage, RPC, logging, CORS, console/browser, encryption, policy, or endpoint changes, and when deciding which security regression tests are required.
+---
+
+# RustFS Security Advisory Lessons
+
+Use this skill as a RustFS-specific security lens before changing or approving code. For the distilled advisory lessons and review patterns, read [advisory-patterns.md](references/advisory-patterns.md).
+
+When currentness matters, fetch the live advisory inventory instead of relying on this skill as a status mirror:
+
+```bash
+gh api repos/rustfs/rustfs/security-advisories --paginate \
+  --jq '.[] | {ghsa_id,state,severity,summary,updated_at}'
+```
+
+Fetch full advisory details only when the live summary suggests a new or changed lesson:
+
+```bash
+gh api repos/rustfs/rustfs/security-advisories/<GHSA_ID>
+```
+
+For the full pattern map, read [advisory-patterns.md](references/advisory-patterns.md).
+
+## Workflow
+
+### 1. Scope the change
+- Identify touched routes, handlers, storage paths, credentials, logs, browser surfaces, CI/release code, and policy checks.
+- Treat these paths as security-sensitive by default: `rustfs/src/admin/`, `rustfs/src/storage/`, `rustfs/src/auth.rs`, `rustfs/src/server/layer.rs`, `crates/iam/`, `crates/policy/`, `crates/credentials/`, `crates/ecstore/src/rpc/`, `crates/rio/`, and console preview/auth code.
+
+### 2. Map to advisory classes
+- Read [advisory-patterns.md](references/advisory-patterns.md) for matching GHSA lessons.
+- Do not rely on advisory titles alone. Confirm whether the issue is authentication, authorization, input validation, storage invariant, browser isolation, logging, or operational hardening.
+
+### 3. Verify fail-closed behavior
+- Check that unauthenticated, wrong-permission, cross-user, cross-bucket, malformed-input, and default-config cases fail explicitly.
+- Prefer exact action/permission checks over broad helper calls or inferred ownership.
+- Confirm lower storage/RPC layers do not bypass checks done in upper layers.
+
+### 4. Require regression evidence
+- For behavior changes, add focused negative tests that reproduce the advisory class.
+- For sensitive fixes, include tests for the bypass form, not only the happy path.
+- If a test is impractical, explain the residual risk and provide a manual verification command.
+
+### 5. Report clearly
+- Lead with concrete findings and file/line evidence.
+- Separate proven vulnerabilities from hardening risks.
+- Avoid exaggerating unauthenticated impact when the code actually rejects unauthenticated requests but allows a low-privileged authenticated bypass.
+
+## Advisory-Derived Guardrails
+
+### Auth and admin authorization
+- Every admin or diagnostic route needs an explicit authn and authz story. Route registration, router whitelist, and handler-level authorization must agree.
+- Match the admin action to the operation exactly. Copy-paste action constants are a known RustFS vulnerability class.
+- Avoid authentication-only helpers for state-changing admin APIs; use `validate_admin_request` or the established equivalent with the right `AdminAction`.
+- Do not assume admin-action `Resource` scoping constrains blast radius unless the policy engine actually enforces resources for that action.
+
+### IAM and service accounts
+- Treat imported IAM payload fields as attacker-controlled: `parent`, `claims`, `accessKey`, `secretKey`, status, policy names, and groups.
+- For service account create/update/import, prove parent ownership or root/admin authority before writing credentials or claims.
+- Do not let `deny_only` or "no explicit deny" become an allow decision that skips required allow checks.
+- Test cross-user list/update/import flows with wrong, correct, self, parent, and root identities.
+
+### S3 copy, multipart, and presigned POST
+- Multipart copy must enforce source `GetObject` and destination `PutObject` semantics equivalent to `CopyObject`, including copy-source and policy conditions.
+- Do not let `CreateMultipartUpload`, `UploadPartCopy`, `CompleteMultipartUpload`, or `AbortMultipartUpload` return success without authorization.
+- Presigned POST policies are server-side contracts. Enforce `content-length-range`, key prefix, exact metadata/content-type, and all signed policy conditions.
+
+### Paths, object keys, and filesystem access
+- Never join untrusted bucket/object/RPC path strings onto filesystem roots without normalization and boundary checks.
+- Reject or safely handle `..`, absolute paths, URL-encoded traversal, platform separators, empty components, and paths that canonicalize outside the intended root.
+- Validate both S3 object-key paths and internode/RPC disk paths; storage helpers can bypass S3 authorization if they trust already-parsed paths.
+
+### Secrets, default credentials, and crypto
+- Do not ship hard-coded shared tokens, HMAC secrets, private keys, or production test keys.
+- Defaults for internode/RPC auth must fail closed for network-reachable deployments or require explicit opt-in with loud warnings.
+- License or token validation must use signatures with embedded public/verifying keys only; do not use private-key decryption as authenticity.
+- Plan key rotation and key IDs when removing exposed keys.
+
+### Logging and debug output
+- Logs must never include access keys beyond safe identifiers, secret keys, session tokens, JWT claims, HMAC secrets, expected signatures, license secrets, or raw response bodies containing credentials.
+- Treat `Debug` implementations, `?value` tracing, merged config dumps, and dependency-level HTTP body logging as leak surfaces.
+- Add log-capture tests or targeted unit tests for redaction wrappers when changing credential structs or response bodies.
+
+### RPC, parsing, and panic safety
+- Treat all RPC payload bytes as attacker-controlled. Replace `unwrap`, `expect`, and panic-prone deserialization with typed errors.
+- Malformed request tests should cover empty bytes, truncated MessagePack/protobuf, invalid enum values, stale timestamps, and invalid signatures.
+- RPC authentication must be independently strong; do not depend on S3 admin credentials unless the fallback is explicit and safe.
+
+### Browser, CORS, and console surfaces
+- Do not reflect arbitrary `Origin` while also allowing credentials. Default CORS should be no CORS unless explicitly configured.
+- Do not render user-controlled object content in a same-origin iframe with console credentials available to JavaScript.
+- Prefer origin separation for object preview/download, `nosniff`, CSP, strict content-type handling, and avoiding durable credentials in `localStorage`.
+- License/version-like metadata endpoints should expose only coarse public data unless authenticated.
+
+### Profiling, debug, and health endpoints
+- Profiling and debug endpoints are not health checks. They require admin auth, opt-in enablement, rate limiting, and safe responses.
+- Do not return absolute filesystem paths or other deployment layout in unauthenticated or low-privilege responses.
+- Ensure health endpoint allowlists cannot accidentally include expensive diagnostics.
+
+### Trusted proxy and network identity
+- Only honor `X-Forwarded-For` or `X-Real-IP` when the request came from a configured trusted proxy.
+- Direct clients must use the socket peer address for `aws:SourceIp` and policy condition evaluation.
+- Add tests for direct spoofed headers and trusted-proxy headers.
+
+### SSE and storage invariants
+- Encryption metadata is not proof that bytes were encrypted on disk.
+- When touching reader/writer wrappers such as hashing, encryption, compression, or warp readers, verify wrapper order and inspect stored bytes in regression tests.
+- Avoid helper shortcuts that unwrap nested readers and accidentally bypass encryption or integrity layers.
+
+## Review Prompts
+
+Use these prompts while reviewing a diff:
+
+- Could a low-privileged authenticated user reach this path with the wrong action, parent, bucket, or source object?
+- Does a public/default/empty config change security behavior from fail-closed to fail-open?
+- Is any attacker-controlled value later used as a path, policy condition, credential identity, log field, URL, Origin, or response body?
+- Is the same operation implemented in multiple paths, such as `CopyObject` vs `UploadPartCopy`, and do all paths enforce the same security contract?
+- Does the test prove the exploit form is denied, or only that the intended form still works?

+# 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-x5xv-223c-8vm7`: console license metadata endpoint was public. Lesson: public metadata endpoints should be coarse or authenticated.
+
+### 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-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.
+
+### S3 copy, multipart, and upload policy validation
+
+- `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.
+
+### 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.
+
+### Secrets, defaults, and cryptographic misuse
+
+- `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-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.
+
+### 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-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.
+
+## Useful Search Seeds
+
+Use these targeted searches when a diff touches security-sensitive code:
+
+```bash
+rg -n "validate_admin_request|check_permissions|AdminAction::|deny_only|is_allowed" rustfs crates
+rg -n "UploadPartCopy|upload_part_copy|CompleteMultipart|PostObject|content-length-range|starts-with" rustfs crates
+rg -n "PathBuf::join|canonicalize|\\.\\.|x-forwarded-for|x-real-ip|SourceIp" rustfs crates
+rg -n "DEFAULT_SECRET|DEFAULT_ACCESS|TEST_PRIVATE_KEY|rustfs rpc|RUSTFS_RPC_SECRET" rustfs crates
+rg -n "debug!|trace!|info!|error!|\\?resp|\\?merged_config|session_token|secret_key" rustfs crates
+rg -n "HashReader|EncryptReader|SSE|server-side encryption|Access-Control-Allow-Credentials|Origin" rustfs crates
+```
+
+## Minimum Regression Test Expectations
+
+- Authz fixes: include unauthenticated, valid low-privilege, wrong-action, correct-action, owner, non-owner, and root/admin cases as applicable.
+- 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.
+- Path fixes: include encoded traversal, absolute path, nested traversal, valid object keys that resemble traversal text but should be rejected, and canonical boundary checks.
+- Logging fixes: assert redacted output for structs and response bodies that may contain credentials.
+- 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.

+# Issue 2815 Local Docker Verification
+
+## Purpose
+
+This directory contains the local distributed Docker verification assets used to validate issue `#2815` against the current source build.
+
+The target behavior is:
+
+- 4-node distributed cluster starts successfully
+- `/health/ready` becomes reachable on each node
+- logs no longer contain `storage_info failed: Io error: wrong msgpack marker FixArray(1)`
+- internode RPC authentication succeeds with an explicit non-default RPC secret
+
+## Files
+
+- `docker-compose.yml`: 4-node distributed cluster using a locally built image
+
+## Data Directories
+
+Create the bind-mount directories before `docker compose up`:
+
+```bash
+mkdir -p .docker/test/issues-2815/data/rustfs{1..4}-disk{0..3}
+```
+
+## Build
+
+Apple Silicon / arm64 host:
+
+```bash
+docker build --platform linux/arm64 -f Dockerfile.source -t rustfs-issue-2815-local .
+```
+
+If you intentionally want amd64 emulation:
+
+```bash
+docker build --platform linux/amd64 -f Dockerfile.source -t rustfs-issue-2815-local .
+```
+
+## Run
+
+```bash
+docker compose -f .docker/test/issues-2815/docker-compose.yml up -d
+```
+
+If the image platform is not `linux/arm64`, align compose explicitly:
+
+```bash
+RUSTFS_DOCKER_PLATFORM=linux/amd64 docker compose -f .docker/test/issues-2815/docker-compose.yml up -d
+```
+
+## Health Checks
+
+Container-level healthcheck is now included and probes:
+
+```bash
+curl -fsS http://127.0.0.1:9000/health
+```
+
+Manual checks:
+
+```bash
+curl -i http://127.0.0.1:9101/health/ready
+curl -i http://127.0.0.1:9102/health/ready
+curl -i http://127.0.0.1:9103/health/ready
+curl -i http://127.0.0.1:9104/health/ready
+```
+
+## RPC Secret Requirement
+
+The current source build no longer reproduces the original `FixArray(1)` decode error from issue `#2815`.
+
+Earlier local Docker attempts failed during erasure bootstrap with:
+
+```text
+No valid auth token
+store init failed to load formats after 10 retries: erasure read quorum
+```
+
+Root cause:
+
+- RPC authentication rejects the default secret `rustfsadmin`
+- distributed local Docker validation therefore needs an explicit non-default secret
+
+This compose now sets both:
+
+- `RUSTFS_SECRET_KEY=issue-2815-secret`
+- `RUSTFS_RPC_SECRET=issue-2815-rpc-secret`
+
+With those values in place, the current 4-node local Docker cluster reaches healthy state and `/health/ready` returns `200`.
+
+In other words:
+
+- `RUSTFS_ACCESS_KEY` may still be `rustfsadmin` for local service credentials if desired
+- `RUSTFS_SECRET_KEY` can still be used for service credentials
+- but RPC authentication must not resolve to the default secret value `rustfsadmin`
+- if `RUSTFS_RPC_SECRET` is unset, the code falls back to `RUSTFS_SECRET_KEY`
+- so at least one of them must provide a non-default shared secret for internode RPC signing
+
+## Suggested Debug Commands
+
+```bash
+docker compose -f .docker/test/issues-2815/docker-compose.yml ps
+docker compose -f .docker/test/issues-2815/docker-compose.yml logs --no-color --tail=200
+docker compose -f .docker/test/issues-2815/docker-compose.yml down -v
+```

+- Read the relevant existing code, tests, and local guidance before changing behavior.
+- State assumptions when they affect the implementation or verification path.
+- If a task has multiple plausible interpretations, list the options briefly and choose the narrowest reasonable path; ask when the ambiguity would make the change risky.
+- For multi-step work, keep the plan minimal and tied to verifiable outcomes.

+## Bird's Eye View
+
+RustFS is a high-performance, S3-compatible distributed object storage system written
+in Rust. It uses erasure coding for data durability, supports multi-tenancy through
+IAM/STS, and provides a web-based admin console.
+
+A running RustFS node exposes:
+
+- **S3 API** (port 9000) — the primary data path for object CRUD
+- **Admin API** (port 9000, `/minio/` prefix) — cluster management, IAM, metrics
+- **Console** (port 9001) — web UI backed by the Admin API
+- **Inter-node RPC** (gRPC/tonic) — cluster communication for distributed mode
+
+The core data flow for a PUT request looks like:
+
+```
+HTTP request
+  → server (TLS, auth, routing, compression)
+    → app/object_usecase (validation, policy, lifecycle)
+      → storage/ecfs (erasure coding, encryption, checksums)
+        → ecstore (disk pool selection, data distribution)
+          → rio (reader pipeline: encrypt → compress → hash → write)
+            → io-core (zero-copy I/O, buffer pool, direct I/O)
+              → local disk / remote disk via RPC
+```
+

+### Main Crate Layers (`rustfs/src/`)
+
+The main crate is organized in layers, top to bottom:
+
+| Layer | Directory | Responsibility |
+|-------|-----------|----------------|
+| **Server** | `server/` | HTTP listener, TLS, CORS, compression, middleware, graceful shutdown |
+| **Admin** | `admin/` | Admin API routing, 30+ handler modules, web console |
+| **App** | `app/` | Use-case orchestration: object_usecase, bucket_usecase, multipart_usecase |
+| **Storage** | `storage/` | S3 API translation, erasure-coded FS, SSE encryption, RPC, concurrency |
+| **Auth** | `auth.rs` | S3 signature verification, credential validation |
+| **Config** | `config/` | CLI parsing, config struct, workload profiles |
+
+A request flows **downward** through the layers. No layer should reach upward
+(e.g., storage must not import from admin).
+
+### Crate Reference
+
+Crates are organized in a dependency DAG with 9 depth levels (0 = leaf, 8 = top):
+
+```
+Depth 0 — LEAF (no internal deps):
+  appauth, checksums, config, credentials, crypto, io-metrics,
+  madmin, s3-common, workers, zip
+
+Depth 1:
+  io-core (→ io-metrics)
+  policy (→ config, credentials, crypto)
+  utils (→ config)                        ⚠️ inverted: utils should be leaf
+
+Depth 2:
+  concurrency, filemeta, keystone, kms, lock, obs,
+  signer, targets, trusted-proxies
+
+Depth 3:
+  common (→ filemeta, madmin)             ⚠️ inverted: common should be leaf
+
+Depth 4:
+  object-capacity, protos, rio
+
+Depth 5 — CORE:
+  ecstore (16 internal deps, 11 dependents — the architectural heart)
+
+Depth 6:
+  audit, heal, iam, metrics, notify, s3select-api, scanner
+
+Depth 7:
+  object-io, protocols, s3select-query
+
+Depth 8 — TOP:
+  rustfs (35 internal deps — the binary, depends on almost everything)
+```

+## Architecture Invariants
+
+> These are rules that the codebase should follow. Some are currently violated
+> (marked with ⚠️). Documenting them here makes the violations explicit and
+> trackable.
+
+1. **Layers flow downward.** Server → Admin/App → Storage → ecstore → rio/io-core.
+   No upward imports.
+
+2. **Leaf crates have zero internal dependencies.** `config`, `credentials`, `crypto`,
+   `io-metrics`, `madmin`, `s3-common` should depend only on external crates.
+   - ⚠️ VIOLATED: `utils` depends on `config`, `common` depends on `filemeta` and `madmin`.
+
+3. **Each type has exactly one definition.** Types shared across crates must be defined
+   in one crate and re-exported or imported by others.
+   - ⚠️ VIOLATED: `ReplicationStats` (4 copies), `LastMinuteLatency` (3 copies),
+     `BackpressureConfig` (3 copies), `DataUsageInfo` (2 copies).
+
+4. **ecstore does not know about HTTP or S3 protocol details.** It operates on
+   storage-level abstractions (objects, buckets, disks, pools).
+
+5. **The `rustfs` binary crate is the only place that wires everything together.**
+   Individual crates should be testable in isolation.
+
+6. **Error types use `thiserror` with descriptive names** (e.g., `StorageError`,
+   not bare `Error`).
+   - ⚠️ VIOLATED: 6 crates use `pub enum Error`; 2 crates use `snafu`;

+
+## Known Structural Issues
+
+> This section documents known problems in the current architecture.
+> It exists so the team can track and address them deliberately.
+
+### Critical
+
+- **common/scanner code duplication (~3K lines).** `scanner` depends on `common`
+  but maintains its own copies of `DataUsageInfo`, `LastMinuteLatency`, and related
+  types instead of importing them.
+
+- **ecstore is a monolith (87K lines, 163 files).** It contains disk management,
+  bucket management, erasure coding, replication, lifecycle, RPC, and configuration
+  — all in one crate. It should be decomposed along its existing subdirectories.
+
+### High
+
+- **Dependency inversions.** `utils → config` and `common → filemeta/madmin` break
+  the layering model. These need to be untangled.
+
+- **Three-layer BackpressureConfig/DeadlockConfig duplication** across io-core,
+  concurrency, and rustfs/storage. Should be defined once with builder/composition.
+
+### Medium
+
+- **Inconsistent error handling.** Three strategies (thiserror/snafu/anyhow) and
+  mixed naming (bare `Error` vs descriptive names).
+
+- **Ambiguous common vs utils boundary.** Both described as "utilities and data
+  structures." Need clear ownership rules.
+
+## Cross-Cutting Concerns
+
+### Error Handling
+
+The project convention is `thiserror` for typed errors with descriptive names.
+See `AGENTS.md`: "Prefer thiserror for library-facing error types."
+
+```rust
+// GOOD
+#[derive(Debug, thiserror::Error)]
+pub enum StorageError {
+    #[error("disk not found: {0}")]
+    DiskNotFound(String),
+}
+
+// AVOID
+pub enum Error { ... }        // too generic
+anyhow::Result<T>             // in library code (OK in tests/CLI)
+```
+
+### Logging & Tracing
+
+- Use `tracing` crate (`info!`, `warn!`, `error!`, `debug!`, `trace!`)
+- Structured fields: `tracing::info!(bucket = %name, "created bucket")`
+- Spans for request-scoped context
+
+### Metrics
+
+- Prometheus-style metrics via `rustfs-obs` runtime and schema
+- I/O-specific counters via `rustfs-io-metrics`
+- Registration happens at crate level, collection/reporting in `rustfs-obs`
+
+### Testing
+
+- Unit tests: `#[cfg(test)] mod tests` in the same file
+- Integration tests: inside respective crates (not top-level `tests/`)
+- E2E tests: `crates/e2e_test/` — tests against a running server
+- Run all: `make test` or `cargo nextest run`
+
+## Startup Sequence
+
+The binary (`main.rs`) boots in this order:
+
+1. Environment variable compatibility (`MINIO_*` → `RUSTFS_*`)
+2. Tokio runtime construction
+3. CLI argument parsing
+4. License, observability, TLS, trusted proxies initialization
+5. Config parsing, server address resolution
+6. Credentials, endpoints, local disks, lock client initialization
+7. Capacity management initialization
+8. HTTP server start (S3 API + optional console)
+9. ECStore initialization (erasure coding storage engine)
+10. Global config, background replication, KMS
+11. Optional: FTP/FTPS/WebDAV servers
+12. Event notifier, audit system, deadlock detector
+13. Bucket metadata, IAM, Keystone, OIDC
+14. Scanner and heal manager
+15. Metrics system, mark `FullReady`
+16. Wait for shutdown signal → graceful shutdown

+## How to Navigate
+
+- **"Where does S3 PutObject go?"**
+  `server/` routes → `app/object_usecase` validates → `storage/ecfs` encodes →
+  `ecstore` distributes → `rio` encrypts/compresses → `io-core` writes
+
+- **"Where are bucket policies enforced?"**
+  `app/bucket_usecase` calls into `crates/policy/`
+
+- **"Where is replication configured?"**
+  `admin/handlers/replication.rs` and `admin/handlers/site_replication.rs` for API,
+  `ecstore/src/bucket/replication/` for engine
+
+- **"Where do I add a new admin endpoint?"**
+  Add handler in `admin/handlers/`, register in `admin/router.rs`
+
+- **"Where do I add a new metric?"**
+  Define descriptor/collector in `crates/obs/src/metrics/`, expose via `/minio/v2/metrics`

   - XML-formatted error responses compatible with S3 API
   - Comprehensive integration documentation with manual testing guide
   - **32 unit and integration tests** covering middleware, auth handlers, task-local storage, and role detection
+- **SFTPv3 Protocol Support**: SSH-hosted SFTPv3 subsystem that translates each file operation into S3 calls against the local object store. Authentication uses IAM credentials (SSH username = access key, SSH password = secret key).
+  - Full SFTPv3 packet coverage: open, read, write, stat, lstat, fstat, mkdir, rmdir, rename, remove, opendir, readdir, realpath, close, plus the rest of the 21-packet specification
+  - Streaming multipart write up to S3's 5 TiB per-file ceiling
+  - Per-handle read-ahead cache with configurable window size and process-wide memory ceiling
+  - Per-session liveness watchdog: Linux probes `/proc/net/tcp` and cancels wedged sessions on the order of 45 seconds; non-Linux falls back to an inactivity ceiling on the order of 30 minutes

+  - Four-layer regression-prevention tests guard against silent feature deletion: compile-time module assertion, module-presence unit test, cross-module `Protocol` enum assertion, end-to-end SSH banner test against the running binary
 
 ### Changed
 - **HTTP Server Stack**: Integrated `KeystoneAuthLayer` middleware from `rustfs-keystone` crate into service stack (positioned after ReadinessGateLayer)
 - **IAMAuth**: Enhanced `get_secret_key()` to return empty secret for Keystone credentials (bypasses signature validation)
 - **Auth Module**: Modified `check_key_valid()` to retrieve Keystone credentials from task-local storage and determine admin status
+- **`StorageBackend` trait**: extended with multipart upload methods (`create_multipart_upload`, `upload_part`, `complete_multipart_upload`, `abort_multipart_upload`) plus `upload_part_copy`. Streaming-upload code path is now available to FTPS, WebDAV, and Swift drivers as well.
+- **`Protocol` enum**: new `Protocol::Sftp` variant with corresponding `S3Action` mappings. Every match arm on `Protocol` updated to handle the new variant exhaustively.
 
 ### Technical Details

@@ -35,12 +45,22 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Integration preserves existing S3 authentication flow while adding Keystone support
 - Zero breaking changes to existing functionality
 - No new top-level directories in main binary crate (middleware lives in integration crate)
+- SSH/SFTP wire handling via the `russh` and `russh-sftp` crates. SFTPv3 framing is implemented by `russh-sftp`; the rustfs-side `SftpDriver` implements `russh_sftp::server::Handler` and dispatches to the storage backend
+- Drop-time abort for in-flight multipart uploads honours IAM Deny on `AbortMultipartUpload`. `start_multipart_upload` caches the authorisation decision so the synchronous `Drop` path can honour Allow / Deny policies without re-querying IAM
+- Per-handle read cache uses an `Arc<AtomicU64>` shared across every `SftpDriver` instance to enforce a process-wide memory ceiling. On ceiling breach the populate is skipped and the read serves correctly via a single-call backend fetch
+- Per-session liveness watchdog runs as a tokio task per accepted connection. Reads `/proc/net/tcp` and `/proc/net/tcp6` to look up the (local, peer) tuple's TCP state and cancels via `tokio_util::sync::CancellationToken` when wedge conditions are confirmed across two consecutive ticks
+- Path canonicalisation rejects paths containing `\0`, `\r`, or `\n` and resolves traversal via `path::clean()` before any backend dispatch
+- Cipher / KEX / MAC / host-key algorithm allowlists are hardcoded with no environment override. Strict-KEX (CVE-2023-48795 / Terrapin) marker presence asserted by unit test
+- Per-session handle cap (default 64, configurable 8 to 1024) with UUID-generated handle ids
+- Crate-level `#![deny(unsafe_code)]` is in force across `crates/protocols`. Socket fd duplication for the watchdog uses the safe `AsFd::try_clone_to_owned` path (Linux/Unix); non-Unix falls back to the inactivity ceiling
+- `cfg(unix)` gating around platform-specific imports (`std::os::fd::AsFd`, `std::os::unix::fs::PermissionsExt`); non-Unix targets fail SFTP at config-load with `SftpInitError::UnsupportedPlatform`
 
 ### Documentation
 - Updated `crates/keystone/README.md` with complete integration architecture and workflow
 - Added detailed manual testing guide with 10 test scenarios
 - Updated main `README.md` to list Keystone authentication as available feature

+  -e RUSTFS_NOTIFY_WEBHOOK_QUEUE_DIR_PRIMARY=/tmp/rustfs-events \
+  rustfs/rustfs:latest
+```
+
+Notes:
+- `RUSTFS_NOTIFY_ENABLE=true` enables the global notify module switch.
+- For ARN `arn:rustfs:sqs::primary:webhook`, use instance-scoped env vars with `_PRIMARY`.
+- If queue dir is omitted, default is `/opt/rustfs/events`; ensure it is writable by the container runtime user.
+- `RUSTFS_NOTIFY_WEBHOOK_SKIP_TLS_VERIFY_PRIMARY` defaults to `false`; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. Prefer `RUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARY` for private CAs.
+
 **NOTE**: We recommend reviewing the `docker-compose.yml` file before running. It defines several services including Grafana, Prometheus, and Jaeger, which are helpful for RustFS observability. If you wish to start Redis or Nginx containers, you can specify the corresponding profiles.

+### OIDC Roles Claim (Microsoft Entra ID)
+
+RustFS supports mapping an OIDC claim containing role values into the existing
+authorization pipeline. The `roles_claim` setting is **optional**: when unset or
+empty, only the `groups` claim contributes to authorization (same as older
+RustFS releases). For Microsoft Entra ID app roles, set `roles_claim=roles` so
+both console admin checks and bucket IAM policies can evaluate those roles.
+
+Example environment configuration (opt-in roles claim):
+
+```bash
+RUSTFS_IDENTITY_OPENID_ENABLE=on
+RUSTFS_IDENTITY_OPENID_CONFIG_URL="https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration"
+RUSTFS_IDENTITY_OPENID_CLIENT_ID="<client-id>"
+RUSTFS_IDENTITY_OPENID_CLIENT_SECRET="<client-secret>"
+RUSTFS_IDENTITY_OPENID_SCOPES="openid,profile,email"
+RUSTFS_IDENTITY_OPENID_GROUPS_CLAIM="groups"
+RUSTFS_IDENTITY_OPENID_ROLES_CLAIM="roles"
+```
+
+Policy condition example (evaluate app roles directly with `jwt:roles`; when
+`roles_claim` is configured, RustFS also merges those values into `jwt:groups`
+for backward compatibility with older policies):
+
+```json
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",

+# Audit Crate Instructions
+
+Applies to `crates/audit/`.
+
+`rustfs-audit` is the domain layer for audit event fan-out and observability.
+It composes shared plugin/runtime abstractions from `rustfs-targets` and keeps
+audit-specific dispatch semantics, state transitions, and metrics in this
+crate.
+
+## Domain Boundaries
+
+- Keep audit-specific behavior here:
+  - audit event shaping and fan-out pipeline
+  - audit system lifecycle/state transitions
+  - audit metrics and reporting
+- Keep shared plugin/runtime mechanics in `rustfs-targets`:
+  - no duplicated replay worker orchestration
+  - no duplicated runtime manager primitives
+  - no plugin install/control-plane modeling in this crate
+
+## Runtime Layering Rules
+
+- `pipeline.rs` hosts:
+  - `AuditPipeline` (dispatch and snapshot access)
+  - `AuditRuntimeFacade` (runtime mutation path)
+  - `AuditRuntimeView` (runtime read path)
+- `registry.rs` should remain the single owner of runtime target container and
+  plugin registry composition for audit.
+- `system.rs` should coordinate lifecycle by calling facade/view/registry
+  boundaries rather than embedding low-level runtime logic.
+
+## Change Style
+
+- Preserve audit delivery semantics and error handling behavior unless the task
+  explicitly changes them.
+- Prefer extending shared abstractions in `rustfs-targets` over patching
+  one-off audit-only runtime flows.
+- Keep logging and observability machine-meaningful; avoid noisy churn in hot
+  dispatch paths.
+
+## Testing
+
+- Keep unit tests close to changed modules.
+- Keep pipeline-layer regressions in `tests/pipeline_layer_test.rs`.
+- Add regression tests for:
+  - runtime facade activation/replace/stop/shutdown behavior
+  - runtime view target/snapshot access
+  - system reload and runtime commit/clear boundaries
+- Suggested validation:
+  - `cargo test -p rustfs-audit`
+  - Focused: `cargo test -p rustfs-audit --test pipeline_layer_test`
+  - Focused: `cargo test -p rustfs-audit pipeline`
+- Full gate before commit: `make pre-commit`
