fix(tier): switch outbound URL check to the operator-overridable policy

The initial fix (routing all warm-tier constructors through validate_outbound_url) rejected the hermetic reliant::tiering e2e suite's real hot->cold connection over 127.0.0.1, since two embedded RustFS servers in that suite talk to each other over loopback by design. validate_outbound_url has no override; OutboundPolicy (already used by webhook targets and OIDC discovery URLs) enforces the identical default restrictions but lets an operator allowlist one exact origin via RUSTFS_OUTBOUND_ALLOW_ORIGINS -- metadata, link-local, and unspecified addresses can never be allowlisted, so this does not reopen the SSRF gap the previous commit closed. Switch every warm-tier constructor (including S3, which folds Wasabi in via new_with_bucket_lookup) to this policy through one shared crates/ecstore/src/services/tier/ warm_backend.rs::validate_tier_endpoint_url helper, replacing the nine scattered validate_outbound_url call sites the previous commit added and consolidating their error(format!) ratchet accounting into one file. Update the e2e suite to set RUSTFS_OUTBOUND_ALLOW_ORIGINS to the cold node's real origin before starting/restarting hot, via a hot_env_for_tier helper, and fix the resulting borrow-checker conflict in the one test that stops cold mid-test by cloning its origin into an owned String first. Also retarget a WarmBackendRustFS unit test that asserted on a now-unreachable local host-missing message: the shared policy's http(s)-only scheme check runs first and is now what actually rejects that fixture's non-http endpoint. Impact: operators with an existing self-hosted RustFS/MinIO/etc. tier whose endpoint is a bare loopback/private/link-local IP literal (not a hostname) need RUSTFS_OUTBOUND_ALLOW_ORIGINS=<origin> set and the server restarted to keep that tier working after this change.
fix(tier): validate outbound URLs for all warm backend providers

 ### S3 object actions, copy, multipart, and upload policy validation

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

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

 - **Per-pool erasure parity**: Erasure parity (STANDARD and reduced-redundancy) is now resolved independently for every pool instead of reusing the first pool's value. A heterogeneous topology — for example a 4-drive pool plus a 2-drive pool created during expansion — previously inherited the first pool's parity and could resolve to zero data shards in the smaller pool, panicking Reed-Solomon construction on write. Automatic parity now resolves per pool (for example `2+2` in the 4-drive pool and `1+1` in the 2-drive pool). Fixes #4801.

 ### Added
- **On-Demand Migration**: Lazy, pull-style migration of an existing S3-compatible bucket into RustFS. A local bucket is attached to an external source bucket; a GET for a key that does not exist locally fetches it from the source, streams it to the client, and stores it locally in the same pass, so every later read is served locally. The module is on by default; set `RUSTFS_ON_DEMAND_MIGRATION_ENABLED=false` on every node to turn it off. A bucket with no source configured behaves exactly as before — the runtime never intervenes on its reads and makes no outbound call. Operator guide at `docs/operations/on-demand-migration.md`.
-  - Per-bucket configuration persisted as `on-demand-migration.json` in the bucket metadata: source provider (`s3`, `aws`, `minio`, `rustfs`, `r2`, `gcs`), endpoint, region, addressing style, credentials and TLS material, an optional key-prefix filter and source-prefix rewrite, and a policy block covering the inline size threshold, multipart part size, concurrency, queue capacity, timeouts, bandwidth limit and negative-cache TTL
-  - Admin routes under `/rustfs/admin/v3/on-demand-migration/{bucket}`: `PUT` (with `?dry-run=true` to validate and probe the source without saving), `GET`, `DELETE`, `GET .../status`, plus `POST .../backfill?op=start|cancel` and `GET .../backfill` for the background full-backfill job with its resumable checkpoint. Authorized by the new `admin:GetBucketOnDemandMigration` and `admin:SetBucketOnDemandMigration` actions; every response redacts `secret_key` and `session_token`
-  - Read paths: an object at or below `policy.inline_max_bytes` (16 MiB by default) is teed to the client and to the local store in a single source read; a larger object or a Range read streams through and a background pull stores the whole object. A HEAD miss is proxied to the source and stores nothing (`policy.head = local_only` disables it). Every source-backed response carries `x-rustfs-on-demand-migration: source`
-  - Protections: a per-source circuit breaker, a per-key negative cache, singleflight per key, a concurrency limit and a bounded pull queue shared by the inline and background paths, an optional bandwidth limit, an anti-loop request marker, and the shared outbound-endpoint (SSRF) policy
-  - Metrics under `rustfs_on_demand_migration_*` (`requests_total`, `pulled_bytes_total`, `pulled_objects_total`, `pull_failures_total`, `inflight_pulls`, `queue_depth`, `source_latency_seconds_*`, `breaker_state`), mirrored per node by the admin status route
-  - Limitations: listings show only local objects (the source is not merged into `ListObjectsV2`); PUT and DELETE never reach the source; a source object updated after it was pulled is not re-fetched; SSE-C source objects are unsupported and answer 424; `Last-Modified` on a pulled object is the local write time, with the source timestamp kept in metadata
 - **NATS JetStream Publish Path**: Opt-in at-least-once delivery for the NATS notify and audit targets. A NATS Core publish flushes to the connection without awaiting a broker acknowledgement, so an event can be lost across a broker restart or a reconnect after the send queue has already cleared it. A queued event now clears only after the JetStream `PublishAck`, so bucket notifications survive those interruptions. Off by default and byte-identical to the NATS Core path when disabled.
  - Three configuration keys per target: `JETSTREAM_ENABLE`, `JETSTREAM_STREAM_NAME`, and `JETSTREAM_ACK_TIMEOUT_SECS`, under the `RUSTFS_NOTIFY_NATS_` and `RUSTFS_AUDIT_NATS_` prefixes
  - Durable store-and-forward with a stable dedup id sent as the `Nats-Msg-Id` header, so a replay after a crash is collapsed by the server duplicate window

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

-`inputs.rustfs.nixosModules.rustfs` 加入 `imports`，并通过运行时密钥文件
-（例如 sops-nix 或 agenix）配置 `accessKeyFile` 与 `secretKeyFile`，避免密钥
-进入 Nix store。客户端包为
-`inputs.rustfs.packages.${pkgs.system}.rustfs-client`，安装后的命令名为 `rc`。

-//! Regression: an object legally committed at degraded write quorum must stay
-//! listable while a *different* drive is offline.
-//!
-//! On a 4-drive EC 2+2 set, a PUT made while one drive is down persists
-//! `xl.meta` on 3 of 4 drives (write quorum). If a different drive later goes
-//! offline before heal converges, a strict latest-listing quorum of 3 can only
-//! ever observe 2 copies, so ListObjectsV2 silently dropped the object even
-//! though GetObject (read quorum 2) still succeeded. Exposed by the flaky
-//! "Mixed-version rolling upgrade from rc.2" CI lane (run 33478999853); the
-//! product fix relaxes the listing's required object quorum by the number of
-//! set drives the listing could not consult (see
-//! `latest_listing_required_object_quorum` in
-//! `crates/ecstore/src/store/list_objects.rs`).

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

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

 # Programmable fake S3 target

-This module is the shared failure-injection boundary for replication end-to-end tests and the programmable external source for on-demand-migration (ODM) tests. It runs an in-process, path-style S3 endpoint backed by `s3s`; no production crate depends on it.
+This module is the shared failure-injection boundary for replication end-to-end tests. It runs an in-process, path-style S3 endpoint backed by `s3s`; no production crate depends on it.

 `FakeS3Target::start()` creates the listener. Add target buckets with `create_bucket`, point a RustFS remote target at `address()`, use `FAKE_ACCESS_KEY` / `FAKE_SECRET_KEY`, then enqueue per-operation faults with `inject`. Faults for one operation are consumed in FIFO order and do not consume faults queued for another operation. A fault is consumed only after `s3s` verifies the full request signature, so anonymous, other-access-key, and bad-signature traffic cannot disturb a script.

-Supported data operations are HeadBucket, GetBucketVersioning, ListObjectsV2, PUT/GET/HEAD/DELETE Object, Get/Put/Delete ObjectTagging (tags live per version; Put replaces the whole set, Delete clears it), and create/upload/complete/abort multipart upload. `create_bucket` models general-purpose buckets in S3's shared global namespace; account-regional namespace buckets and their `-an` names are intentionally out of scope. Buckets created with `create_bucket` are versioned: PUT creates a version, DELETE without `versionId` creates a delete marker, and DELETE with `versionId` removes exactly that version. Internal source version IDs must be UUIDs and are stored canonically. Source mtime is honored only for source-replication PUT/DELETE requests; absent or invalid values use receipt time, matching RustFS, while multipart completion always uses receipt time. Replicated versions are ordered newest-first by source mtime so late older versions and delete markers do not become current. Equal mtimes prefer objects over delete markers, then canonical UUID order; RustFS's internal FileMeta signature tie-break is intentionally out of scope because it is not part of the target S3 protocol. Multipart part numbers follow S3's `1..=10000` range, and every completed part except the final part must be at least 5 MiB.

Multipart part numbers follow S3's `1..=10000` range, and every completed part except the final part must be at least 5 MiB.

-`create_bucket_with_object_lock(name)` creates a versioned bucket whose GetObjectLockConfiguration reports `Enabled`; every other bucket answers `ObjectLockConfigurationNotFoundError`, the code RustFS's replication-check classifies as "not enabled". Three switches model remote-target behaviors the fleet has shown, so the outbound target matrix (`crates/e2e_test/src/replication_target_matrix_test.rs`) can replicate every object shape against each: `assign_own_version_ids(true)` ignores the source version id and mints its own (AWS S3 / Wasabi); `reject_aws_chunked_uploads(true)` refuses any PutObject or UploadPart announcing `aws-chunked` framing (`Content-Encoding: aws-chunked`, an `x-amz-trailer`, or a `STREAMING-*` payload hash) with `InvalidRequest` before the body is read (SeaweedFS 3.97, rustfs#6853); `require_checksum_for_object_lock(true)` rejects a PutObject carrying any `x-amz-object-lock-*` header unless it also carries `Content-MD5`, an `x-amz-checksum-*` header, or `x-amz-sdk-checksum-algorithm` (AWS S3 / MinIO, rustfs#7082). Independently of that switch, a `Content-MD5` header is always verified against the body and a mismatch answers `BadDigest`.
+Fault actions cover HTTP 401/403/503 responses, pre-dispatch delay, connection abort when a logical request-body threshold is reached, streaming slow drain, and a deliberately wrong response ETag (including multipart-complete XML). `requests()` returns the ordered, credential-free request journal for assertions. Each record also journals a `ProxyHeaderSnapshot` — the read-proxy anti-loop marker (`x-{rustfs,minio}-source-proxy-request`), the replication-check exemption header, and the client SSE-C header family (algorithm and key-MD5 values; for the key itself only its presence) — so proxy tests can pin the exact wire contract.

-`create_bucket_with_mode(name, BucketMode::Unversioned)` models a plain migration source: PUT overwrites in place, DELETE removes the key without a delete marker, GetBucketVersioning reports no status, and no `x-amz-version-id` is returned by PUT, GET, HEAD, tagging, or multipart completion. The only `versionId` such a bucket accepts is `null`; any other value is rejected with `InvalidArgument`. The mode is fixed at creation.
-
-ListObjectsV2 lists current versions only (a key whose newest version is a delete marker is hidden) in byte order and supports `prefix`, `delimiter`, `max-keys` (clamped to 1000), `start-after`, and `continuation-token`; common prefixes count toward `max-keys`, `IsTruncated` / `NextContinuationToken` / `KeyCount` follow S3, and continuation tokens are opaque. `encoding-type` and `fetch-owner` are accepted but ignored, and ListObjects (v1) is not implemented. GET and HEAD honor `Range` in the `bytes=first-last`, `bytes=first-`, and `bytes=-suffix` forms with a 206 status, exact `Content-Range`, and `Accept-Ranges: bytes`; unsatisfiable ranges answer 416 `InvalidRange` with `Content-Range: bytes */<length>`. PUT and CreateMultipartUpload accept `Content-Type`, `Content-Encoding`, `Content-Disposition`, `Content-Language`, `Cache-Control`, `Expires`, and `x-amz-meta-*` (names stored lowercased), and HEAD/GET replay them verbatim together with `Last-Modified` and the ETag (hex MD5 for single PUTs, `<md5-of-part-md5s>-<parts>` for multipart objects). `put_seed_object` stores an object directly, bypassing the wire, the fault script, and the journal, so a source can be seeded without polluting the assertions a scenario later makes.
-
-Fault actions cover HTTP 401/403/503 responses (`Status`), any 4xx/5xx status paired with the matching S3 error code (`ResponseStatus`), pre-dispatch delay, holding a fully computed successful response before its first byte (`Stall`), connection abort when a logical request-body threshold is reached, GetObject bodies cut off after N bytes while `Content-Length` announces the full size (`TruncateBodyAt`), GetObject bodies delivered in fixed slices with a pause between them (`SlowSendBody`, a mid-body stall rather than a first-byte one), streaming slow drain, and a deliberately wrong response ETag (including multipart-complete XML). `requests()` returns the ordered, credential-free request journal for assertions and `count_requests(operation, key)` counts entries for one exact key. Each record journals the `Range` and `User-Agent` request headers, the ListObjectsV2 `prefix` and `continuation-token` query values, a `TransportSnapshot` — whether the body was announced as `aws-chunked`, the verbatim `Content-MD5`, the sorted `x-amz-checksum-*` / `x-amz-sdk-checksum-algorithm` header names, and whether any `x-amz-object-lock-*` header was present — and a `ProxyHeaderSnapshot` — the read-proxy anti-loop marker (`x-{rustfs,minio}-source-proxy-request`), the replication-check exemption header, and the client SSE-C header family (algorithm and key-MD5 values; for the key itself only its presence) — so proxy tests can pin the exact wire contract.

-The listener is loopback-only. It admits at most 64 active connections and two concurrently buffered request bodies; authenticated multipart-complete XML collection and assembly take both body permits. Keep-alive is disabled, request-header reads are bounded to 30 seconds, a parsed request is bounded to 65 seconds, and the complete connection lifetime is bounded to 100 seconds. It retains at most 256 buckets, 4,096 journal entries, 4,096 scripted faults, 4,096 object versions, 256 multipart uploads, and 10,000 multipart parts. Retained identifiers are capped at 1 KiB, user metadata at 2 KiB, and content type and each standard object header at 1 KiB. By default a PUT or uploaded part is capped at 64 MiB and a completed multipart object and all stored object/part data are capped at 128 MiB; `FakeS3Target::start_with_options(FakeS3TargetOptions { max_object_bytes })` raises the object cap up to 256 MiB, and the total budget then becomes twice the object cap (never below 128 MiB). Body drain, body-permit waits, delay, stall, and slow-drain execution are bounded to 30 seconds; each slow-drain slice delay must be below that bound.
