DO NOT MERGE: retrigger CI after base change

chore(gateway): record the ignored microbenchmarks merged from main

main added three throughput microbenchmarks that are ignored by design
(#9217): one each in rustfs-checksums, rustfs-rio and rustfs-utils. The
test-count ratchet treats a higher ignored count as a failure until the
row is raised, so raise those three rows to 1 and tighten the test rows
to the merged tree with --update.

-# s3-tests reference parity lane (rustfs/backlog#2773).
-#
-# Runs the ceph/s3-tests implemented list (scripts/s3-tests/implemented_tests.txt)
-# against every target in .config/reference-parity-targets.toml and fails on
-# any per-node-id difference between a candidate and the reference:
-#
-#   - reference: the release pinned in .config/reference-binary.toml, downloaded
-#     and sha256-verified by .github/actions/reference-binary;
-#   - candidate targets: the debug binary built from this checkout exactly as
-#     ci.yml's build-rustfs-debug-binary job builds it for S3 Implemented Tests.
-#
-# Every target runs the same harness (scripts/s3-tests/run.sh from this
-# checkout), test list and server configuration on its own hosted runner. A
-# target's failures get one rerun against a fresh server; a case that passes it
-# is flaky, not a difference. scripts/s3-tests/reference_parity.py judges the
-# result and honours .config/reference-parity-tolerated.txt, whose entries must
-# each match a real difference.
-#
-# Report-only: not part of the Test and Lint aggregate. Scheduled failures are
-# owned by the scheduled-validation watchdog (.github/scheduled-validations.json).

-//! The gateway's [`BucketOwnerSource`]: the one owner RustFS reports, for a bucket that exists.
-//!
-//! Responsible for: confirming through a [`BucketLookup`] that a bucket exists, answering the
-//! single owner id the deployment reports ([`RustfsBucketOwners::new`]) for it, and turning every
-//! outcome that is not a usable owner into the gateway's one refusal, [`BucketOwnerError`].
-//! NOT responsible for: choosing the owner id (the binary passes the constant it already reports
-//! as the owner in listings), comparing it with `x-amz-expected-bucket-owner` (the gateway does,
-//! byte for byte), or authorizing anything.
-//! Upstream: the gateway's expected-owner check, which consults this source only when a request
-//! carries the header, after authorization allowed it. Downstream: the lookup the binary supplies
-//! over the ecstore bucket metadata system.
-//!
-//! # What an owner is in RustFS
-//!
-//! RustFS stores no per-bucket owner: bucket ACL writes are no-ops and nothing writes the ACL
-//! document, so the only owner RustFS reports anywhere (ListBuckets, ACL and multipart listings)
-//! is one constant. The source answers exactly that constant. A caller therefore passes the
-//! gateway's check only by presenting the owner id RustFS lists, which separates no tenants; it is
-//! a compatibility answer, and the constant's own documentation says it must not decide
-//! authorization.
-//!
-//! # Difference from legacy (ledger entry R-071)
-//!
-//! Legacy RustFS ignores `x-amz-expected-bucket-owner` entirely. On the gateway stack a request
-//! carrying it is served only when the value equals the reported owner id; otherwise it is `403
-//! AccessDenied`. A missing bucket and a backend failure with the header present are also `403`
-//! at the pinned gateway, where legacy answers `404` and `5xx`: [`BucketOwnerError`] has one value,
-//! so it cannot express either. [`RustfsBucketOwners::resolve`] keeps the two apart at this
-//! adapter's boundary so the gateway can surface them once it grows the classes.

-//! The gateway's [`HostResolver`], built from RustFS's configured domain list.
-//!
-//! Responsible for: turning the `RUSTFS_SERVER_DOMAINS` list into the gateway's legacy RustFS
-//! virtual-host resolver.
-//! NOT responsible for: parsing a `Host` header, matching a domain, validating bucket names (all
-//! done by [`LegacyRustfsVirtualHosts`]), reading the environment, or deciding that a console
-//! deployment serves no domains (the caller passes an empty list then, as `s3_host_domains` in
-//! `rustfs/src/server/http.rs` returns `None`). An empty list needs no branch here:
-//! [`LegacyRustfsVirtualHosts`] built from no domain reads every host path-style, exactly as the
-//! gateway's `PathStyleOnly` does.
-//! Upstream: the RustFS configuration (`Config::server_domains`). Downstream: the gateway's
-//! `ServiceBuilder`, which holds the resolver as `Arc<dyn HostResolver>`.
-//!
-//! # What "the same as `MultiDomain`" means
-//!
-//! RustFS today hands the same list to the s3s framework's multi-domain host, which ignores ports
-//! on both sides when matching a domain, takes the whole prefix in front of a matched domain as
-//! the bucket, compares a domain exactly (so a host is matched on the case it arrives in), and,
-//! for a host no domain matches, falls back to CNAME-style: a host that is itself a bucket name
-//! (lower-cased) is that bucket. [`LegacyRustfsVirtualHosts`] reproduces exactly that.
-//!
-//! What reads **path-style**: an empty domain list; a configured domain itself, with or without a
-//! port; an IP address, or a socket address (`10.0.0.1`, `[::1]:9000`); a host that is a valid
-//! domain but, lower-cased, is no bucket name (it carries a port, is over 63 bytes, or starts
-//! with `xn--`). What reads as a **bucket**: anything under a configured domain, and any other
-//! bucket-shaped host, which is a bucket of its own (`localhost`, `badexample.com`, `EXAMPLE.COM`).
-//! What is **refused** before routing: a host that is no domain (`under_score.org`, a bare
-//! `[::1]`, a trailing dot), and a bucket under a domain that the bucket rules refuse
-//! (`PHOTOS.example.com`, `ab.example.com`). The tests below pin each of those readings.

-//! The gateway's [`PolicySource`], answered by RustFS IAM.
-//!
-//! Responsible for: the one reading of the caller's IAM facts a request is judged against — which
-//! principal kind it is, the user it acts for, its groups, its token claims, and whether it owns
-//! the deployment — packed as a [`RustfsPrincipal`] into the gateway's [`PolicySnapshot`].
-//! NOT responsible for: evaluating any policy, choosing which policy documents apply (that stays
-//! in `IamSys::is_allowed`, which owns the STS, OIDC, session-policy and service-account rules), or
-//! verifying the signature or the session token (the gateway did both before calling this).
-//! Upstream: the gateway's verified [`Identity`]. Downstream: the RustFS authorizer, which reads
-//! the payload back with `PolicySnapshot::get::<RustfsPrincipal>()`.
-//!
-//! # Failure classes
-//!
-//! Every refusal is a [`PolicyError`] with a constant label and nothing from IAM or the request:
-//! IAM not ready, not initialized, or failing, or root credentials not initialized, is
-//! [`PolicyError::unavailable`]; a principal IAM no longer knows is [`UNKNOWN_PRINCIPAL`]; a
-//! disabled one, or one whose secret fails the effective-length rule, is
-//! [`DISABLED_PRINCIPAL`]; an identity
-//! whose credential kind disagrees with IAM's record is [`SESSION_MISMATCH`]; a token whose claims
-//! cannot be read is [`PolicyError::malformed`]. None of them is ever an empty snapshot: an empty
-//! snapshot is what an anonymous caller gets, and answering a fault with it would judge an
-//! authenticated caller as anonymous.
-//!
-//! # Secret handling
-//!
-//! [`RustfsPrincipal`] holds no secret key and no session token, and implements no `Debug`, so a
-//! snapshot formatted into a log cannot print its claims either. The root credentials and the STS
-//! token-signing key are read per request from the shared [`RootSource`] and never stored here.

-//! The request id RustFS's outer layer minted, handed to the gateway as its own when that is safe.
-//!
-//! Responsible for: reading the id from the context the outer layer put in the request's
-//! extensions ([`RequestIdCarrier`]) and, when it is inside the gateway's identifier alphabet and
-//! length, inserting it as the gateway's [`HostRequestId`].
-//! NOT responsible for: minting any id, refusing any request (nothing here can fail a request),
-//! choosing the response headers (the gateway writes `x-amz-request-id` from the id it was
-//! handed, and RustFS's outer layer overwrites that header on S3 paths), or the layer that mints
-//! (`rustfs/src/server/layer.rs`). It never reads a header itself.
-//! Upstream: RustFS's `RequestContext`, which the binary makes a [`RequestIdCarrier`]. Downstream:
-//! the gateway service, which reads the [`HostRequestId`] extension once, at the top.
-//!
-//! # Whose id it is
-//!
-//! On S3 paths the outer layer mints a server-owned UUID. On admin, STS and console paths the
-//! context copies the caller's `x-request-id` (or `x-amz-request-id`), as legacy does, so there
-//! the id can be caller-chosen. Either way the id is attached only when it is inert, that is 1 to
-//! 64 bytes of ASCII letters, digits, `-`, `.`, `_` and `~`, which is safe in a header, an XML
-//! document and a log line. Anything else is not attached and the request is **forwarded
-//! unchanged**: the gateway then mints its own id. No request is ever refused because of its id.
-//!
-//! # Known difference when nothing is attached
-//!
-//! The gateway answers with the id it minted (error body `<RequestId>`, its events and audit
-//! records) while, on S3 paths, the outer layer overwrites the response header with RustFS's id.
-//! So for such a request the header and the error body name different ids. That needs a caller-
-//! chosen id outside the alphabet, or a request that never passed the outer layer.
-//!
-//! # Why this is not a `TraceSource`
-//!
-//! The gateway's `TraceSource::mint` takes no request, so a source cannot read the id RustFS
-//! already minted; the gateway's documented path for a host that identifies its own requests is
-//! the [`HostRequestId`] extension, and this module fills it.
-//!
-//! # Why a carrier trait

Use `REPLACE` with an explicit `x-amz-tagging` to copy without the tagging grant. |

A folder completes with up to 262,144 UUID-named direct children or about 16.7 million other direct children per drive when the drive can walk them within the time limit (a warm cache walks roughly 25,000 UUID-named children per second; a cold HDD far fewer); inside a UUID-named child only journal files and data-directory markers are examined, so a child key's own `xl.meta`, data directories or children cost 1/64 each. |

The window is one bucket listing long. |

-"""Guard: tests outside an operation's owning family call its use-case only through the test seam.
-
-Preparatory refactor P4 of the s3s-to-gateway migration. Each migration batch
-changes the use-case signatures of its own operations. Tests owned by another
-family that call those entry points as an oracle would break and pull a second
-batch into the same file, so they call the `#[cfg(test)]` seams in
-rustfs/src/app/test_seams/ instead; the owning batch then edits one seam body.
-
-For every entry point in SEAMS this guard fails when
-
-  * a direct method call `.execute_<op>(` appears in test code (a module or
-    item under `#[cfg(test)]`, a file whose module declaration or an ancestor's
-    is under `#[cfg(test)]`, or any file under rustfs/tests/ or rustfs/benches/)
-    in a file that is neither the seam nor one of the operation's owner files;
-  * the seam file is missing, or no longer calls the entry point exactly once;
-  * an owner file listed below does not exist (a stale table must not widen
-    what passes);
-  * a file holding a direct call cannot be placed in the module tree;
-  * no Rust file is found at all.
-
-Production calls (the legacy S3 trait, admin and metadata routes) are not test
-code and are not judged here. Comments and string literals are ignored.

-"""Split rustfs/src/app/lifecycle_transition_api_test.rs into one file per operation owner.

-Preparatory refactor P4 for the s3s-to-gateway migration. Nine batches each
-migrate one family of S3 operations and change that family's use-case
-signatures. While every lifecycle integration test lives in one 3,700-line
-file, two batches edit the same file. This codemod moves every top-level item
-of that file, verbatim with its attributes and comments, into one of the
-module files below, chosen by the explicit ASSIGNMENT table:
-
-  lifecycle_transition_api_test.rs      module root: license header, the
-                                        original `use` block, module list
-  lifecycle_transition_api_test/
-    common.rs        shared fixtures (no owner; frozen during batches)
-    transition.rs    ILM transition-engine tests that call no S3 use-case
-    lifecycle_config.rs  PutBucketLifecycleConfiguration (batch A3)
-    object_lock.rs   PutObjectRetention / PutObjectLegalHold (batch B1)
-    put.rs           PutObject (batch D)
-    copy.rs          CopyObject, including tests that mix put and copy (batch E)
-    delete.rs        DeleteObject / DeleteObjects (batch E)

-Items are moved verbatim. The only rewrites, applied to moved items and
-nowhere else, are the ones a move out of the parent module requires:
-
-  * `super::` becomes `super::super::` (the items now live one module deeper);
-  * `s3s::S3ErrorCode` becomes `S3ErrorCode`, imported once in the module root
-    from `crate::app::storage_api::s3`, and a function-local `use s3s::S3;`
-    becomes `use crate::app::storage_api::s3::S3;`, so no new file names s3s
-    (scripts/check_s3s_footprint.sh counts files);
-  * items placed in common.rs that a sibling file uses gain `pub(super)`;
-  * a call to a test seam's use-case entry point (`execute_get_object`,
-    `execute_head_object`, `execute_list_objects_v2`, `execute_put_object`) in
-    a file that does not own that operation becomes a call to the seam in
-    `crate::app::test_seams` with the same arguments (scripts/check_test_seams.py).
-
-Every non-blank line of the input lands in exactly one output file. The run
-fails (exit 1) and writes nothing when an item is missing from ASSIGNMENT, an
-ASSIGNMENT entry names no item, an item would be moved twice, a moved file
-still names s3s, or a cross-owner seam call cannot be rewritten.
-
-Usage:
-  scripts/codemods/split_lifecycle_transition_api_test.py [--no-fmt]
-  scripts/codemods/split_lifecycle_transition_api_test.py --self-test
-
-The input must be the unsplit file. A second run over the split tree finds the
-module root instead and exits 1 without writing; to regenerate, restore the
-unsplit file (for example `git show <rev>:rustfs/src/app/lifecycle_transition_api_test.rs`),
-re-run, and the output is byte-identical to the committed split. Unless
---no-fmt is given, `rustfmt --edition 2024` formats the written files.
