* fix(storage): restore multipart disk compression and make the legacy decompressor resumable
Multipart uploads have bypassed disk compression since #5169 removed the session marker as a stopgap for mid-stream GET failures. The actual root cause was never the multipart layout: the legacy DecompressReader reset its payload consumption state on every poll re-entry, so a Poll::Pending in the middle of a block payload (routine under the erasure duplex) desynchronized the block framing and surfaced as LZ4 frameType errors. This rewrites the decoder as a resumable state machine, restores the multipart session compression marker, reports logical part sizes in ListParts, and makes the rebalance migration read raw stored bytes so compressed and encrypted objects survive migration verbatim.
Fixes#5957. Internal tracking: backlog#1848, backlog#1850.
* feat(storage): stage multipart compression behind RUSTFS_COMPRESSION_MULTIPART_ENABLED
Review follow-up: a rolling-upgrade window must not create new compressed multipart objects while pre-fix nodes (whose decompressor is not resumable) may still serve reads. The session marker is now additionally gated on RUSTFS_COMPRESSION_MULTIPART_ENABLED, default off, so the restored capability stays dark until the operator confirms fleet convergence. The default flips per the multipart-compression-default-off-window entry in docs/architecture/compat-cleanup-register.md once the minimum supported direct-upgrade release ships the resumable decoder.
* chore(compat): satisfy the cleanup-register guard for the multipart compression switch
The architecture guard requires every backticked identifier in a register entry to carry a RUSTFS_COMPAT_TODO source marker: keep only the entry slug in backticks, and add the marker (with its literal Remove-after condition) at the switch definition.
* chore(rio): drop a dead store in the poison guard and note the end-block branch
Review follow-up: the poison gate re-assigned an already-true flag, and the COMPRESS_TYPE_END branch reads as dead without stating that the writer never emits an end block — that absence is exactly what lets concatenated per-part streams decode as one.
* fix(s3): report empty compressed multipart part size
* fix(s3): report empty encrypted multipart part size
* fix(site-replication): route every state RMW through the locked transaction
P1-15 PR2 (rustfs/backlog#1796, batch B2 of rustfs/backlog#1675), the
follow-up promised by rustfs/rustfs#5882.
PR1 left ~26 read-modify-write call sites on
config/site-replication/state.json in the pre-transaction shape: a
process-local mutex around load / mutate / save, each IO taking its own
object lock. Nothing held a distributed lock across the whole sequence, so
two nodes of one site still lost each other's updates, and the transitional
mutex kept the old shape available to copy.
Every remaining RMW now runs inside update_site_replication_state;
read-only sites use load_site_replication_state, whose object read comes
with the object-level read lock. SITE_REPLICATION_STATE_LOCK and its owner
helper are gone, together with their architecture-guard allowlist entry and
inventory row.
The multi-stage flows (add / edit / peer join / peer edit / remove / rotate)
keep their updated_at and pending-id CAS, but the CAS now runs inside the
transaction that writes, against the state that transaction loaded. Peer
probes, IAM work and fan-outs run between transactions and hold no lock at
all — the add no longer blocks every writer of the site across its peer join
round trips, and it re-checks the precondition right after the capability
probes so the common race is rejected before any IAM write or remote join.
When the add's commit CAS still fails, the error says the peers may already
be joined and that re-running the add reconverges. The add adopts only the
fields it computed (exhaustive destructure — adding a state field is a
compile error until classified); fields owned by writers that do not bump
updated_at keep their freshly loaded values.
Ordering of peer-edit deliveries now rests on the generation fence landed in
PR1 rather than on a guard that could never order two nodes: the add's
finalize fan-out carries the generation allocated in its commit. An accepted
peer join PRESERVES the applied-generation high-water marks — join fan-outs
are routine (adds and rotations both deliver SRPeerJoin to existing peers),
so wiping them would let stalled older edits land after any join; the
unilateral-removal rejoin misfence that a wipe would have patched is
pre-existing since the fence landed and needs an epoch in the fence instead.
The rotation handler now takes the lifecycle guard: the background
service-account reconciler runs its repair under a lifecycle try-acquire,
and its pending-rotation precheck is only sound if a rotation cannot start
mid-repair — an exclusion the removed process mutex used to provide as a
side effect.
update_site_replication_state_when_changed adds persist-or-skip so ack
markers and pending-clearing paths stop rewriting the object on a miss —
load-bearing, because the shared persist helper clears the whole object for
a ≤1-peer pending-free state — and save_site_replication_state is now
cfg(test): the pre-P1-15 shape can no longer be written in production code.
No on-disk format change.

* fix(site-replication): serialize peer-join admission around its IAM write
Review follow-up (overtrue): two joins accepted by the same node could
interleave as "A checks a stale snapshot and pauses reading its body, B
applies secret B and commits, A resumes, overwrites IAM with secret A, and
A's commit is refused as superseded" — the persisted state advertised B's
contract while IAM only accepted A's secret, failing every peer
control-plane call. The pre-P1-15 process mutex serialized same-node joins
end to end; removing it dropped that exclusion.
admit_peer_join now runs the staleness check, the IAM upsert and the state
commit under the lifecycle guard, with the authoritative pre-check taken
against a load under that guard BEFORE IAM changes anything. The closing
transaction still re-checks staleness: the guard is process-local (exactly
as far as the old mutex reached) and the state-object lock arbitrates joins
accepted by different nodes. The body is fully read before the guard so a
stalling sender cannot block add/remove/rotate/reconciler.
The IAM step is injected, and the gated-body regression test reproduces the
review's ordering: join A is held mid-IAM while a newer join B arrives; B
must wait at the guard, and both IAM order and the final persisted state end
on B. Mutation-verified: removing the lifecycle guard from admit_peer_join
turns the test red.

* fix(site-replication): fence peer-join admission across nodes
Review follow-up (overtrue, round 2): the lifecycle guard only serializes
joins within one process. Node A could pass the staleness check for an
older T1, node B write secret B to IAM and commit a newer T2, and node A
then overwrite IAM with secret A while its own state commit is refused as
superseded — state advertising T2's contract while IAM only accepts A's
secret.
The admission (staleness check -> IAM upsert -> state commit) now also runs
under a distributed join-admission lock, a namespace-lock key with no
backing object, following the repair execution lock's pattern — including
its nesting of config-object locks (admission -> state), and delegating
crash safety to the lock subsystem's lease expiry instead of a hand-rolled
TTL. The staleness check runs against a load taken inside the lock, before
IAM changes anything, so a superseded join exits without touching IAM. The
closing transaction keeps its re-check for defence in depth and for
old-version nodes that do not take the admission lock during a rolling
upgrade (that mixed-version window keeps today's behavior and closes when
the upgrade completes).
admit_peer_join_across_nodes is the admission minus the process-local
lifecycle guard — exactly what a second node runs — and the new
separate-nodes regression test drives it directly with join A gated
mid-IAM: join B must wait at the distributed lock, and both the IAM write
order and the final persisted state end on B. Mutation-verified: removing
the admission lock turns the test red while the same-node test (which
drives the full admit_peer_join) stays green.

* fix(tier): decrypt transitioned objects instead of serving their ciphertext
A GET on a managed-SSE object that lifecycle had transitioned to a remote tier returned the ciphertext with the plaintext's Content-Length and no error: silent corruption on read-through, and worse than a failed request because nothing signals it. Restore of the same object failed server-side with IncompleteBody while POST ?restore still answered 200, so the object simply never came back and HEAD never showed an x-amz-restore marker.
Both symptoms are one cause. The transitioned read path built its fetch through new_getobjectreader, which decides nothing about encryption: it derived the range from the parts table — whose sizes are PLAINTEXT sizes — then used that range to fetch the object's STORED bytes from the tier, and handed the stream to the caller without any decrypt transform. The GET therefore served the first plaintext-length bytes of ciphertext; the restore copy-back, which validates against the stored size, came up short by exactly the encryption overhead.
The path now builds the same ReadPlan the local read path uses, so a single place decides how stored bytes map to requested bytes. ReadPlan gains a two-phase API — build_for_request to learn the storage coordinates before issuing the tier fetch, into_object_reader to wrap the returned stream — because the tier fetch has to be positioned before a stream exists. The encryption resolver reaches the path from InstanceContext, the same source the local read uses.
A restore read additionally stops synthesizing a range from the part number. A restore serves the stored representation (restore_request_active already forces the Plain branch), so a plaintext-coordinate range would be reinterpreted as a storage range and truncate the payload by its encoding overhead. An explicit caller range is already in storage coordinates on that path and is still honored, which two existing tests pin.
crates/e2e_test/src/kms/kms_ilm_sse_kms_test.rs drops its #[ignore]: the transition test now runs and asserts the plaintext round-trips byte-identically through transition, read-through and restore. The same file had its enforcement switch stuck at false from a control experiment; it is back to true, so the test again exercises what its name and module docs claim.
Fixes#6025. Refs rustfs/backlog#1582, rustfs/backlog#1637.
* test(tier): pass resolver to transitioned reader tests
Removing the blanket exposes eighteen items. Six are deleted; the rest belong to one feature that was never wired up.
crates/ecstore/src/data_usage/local_snapshot.rs and its aggregation entry point, aggregate_local_snapshots, form a complete per-disk usage-snapshot feature: read/write of snapshot files under the metadata bucket, cross-disk aggregation, and tests. Nothing calls it. It landed in #5307 on 2026-07-27 and git log -S over the whole history shows the entry point has never had a caller; the live data-usage path is load_data_usage_from_backend / store_data_usage_in_backend. Rather than delete a recent, tested feature on cleanup grounds, the module gets a header explaining the situation and its items carry individual allows, so the gap stays greppable without reintroducing a blanket. One commit flips this to deletion if that is preferred.
Deleted:
- DATA_USAGE_BLOOM_NAME together with DATA_USAGE_BLOOM_NAME_PATH. Both are a dead duplicate of the pair in crates/scanner/src/data_usage_define.rs, which has roughly fifty consumers across scanner.rs and remote_scanner.rs; the ecstore copies have none.
- increment_bucket_usage_memory and decrement_bucket_usage_memory, thin wrappers over the live record_bucket_object_write_memory and record_bucket_object_delete_memory.
- sync_memory_cache_with_backend, whose doc comment says it is "called by scanner" — nothing calls it.
- create_cache_entry_from_summary and cache_to_data_usage_info, neither with a consumer in any lane.
resolve_loaded_snapshot is kept with an allow: nine tests in the same file assert its primary/backup fallback.
Verification, four lanes warning-free: default, --tests, --features rio-v2 --tests, --features test-util --tests. rustfs-scanner still compiles clean. cargo nextest run -p rustfs-ecstore 4041 passed; clippy --lib --tests -D warnings clean; make pre-commit exit 0.

Store doubles: NoopTableCatalogStore (193 lines, a pure stub answering "nothing here") and TestTableCatalogStore (416 lines, a stateful fake with commit pauses and failure injection) move into test_support.rs, along with TestCatalogPublishPause which the latter needs. Per the issue's ruling both shapes are kept — they are different tools, not duplicates of each other. Being honest about the benefit: this does not reduce the number of TableCatalogStore implementations, it puts both in one file so a trait change is one file to edit instead of two.
row_level_conflict fold: rejects_stale_new_manifest_sequence, rejects_stale_added_entry_sequence, and rejects_historical_change_in_new_manifest were identical apart from four literals (manifest-list sequence, data-file name, manifest-entry snapshot id, failure message). They become one table-driven test with three rows, each row keeping its original values, and every assertion carries the case name.
Verification: cargo test -p rustfs --lib table_catalog 479 passed and --lib admin::handlers::table_catalog 165 passed (both down exactly 2 from the 3->1 fold; the store filter is a substring match that also covers the admin tests); clippy --lib --tests -D warnings clean; make pre-commit green.

Removing the blanket exposes twenty-five items across tier, notification and rebalance. Only eight are deleted — the lowest ratio of this burn-down so far, and the reason is that these subsystems carry heavy test coverage, so the blanket was mostly hiding test-only seams rather than dead weight.
Deleted:
- crates/ecstore/src/services/tier/warm_backend_s3sdk.rs entirely (200 lines). Its WarmBackendS3 is never constructed; the type of the same name in warm_backend_s3.rs is the live one, wrapped by the Azure backend. Two implementations of one S3 warm backend, one of them never wired.
- TierConfigMgr::begin_publish_transition and publish_candidate_inner, thin wrappers whose _with_allowed_mutation_blocks siblings carry every real caller, plus retire_driver.
- The GCS backend's MAX_MULTIPART_PUT_OBJECT_SIZE, MAX_PARTS_COUNT and MIN_PART_SIZE, and its write-only storage_class field.
- mark_started_rebalance_pools_stopped and the RStats alias.
Two deletions were withdrawn after a per-name grep, both because of an inference rather than a check:
AsyncBatchProcessor::new was deleted on the strength of grepping only BATCH_PROCESSOR_OPERATION_CUSTOM, whose two hits are its definition and its use inside new. That looked like a self-contained dead pair; new in fact has seven test callers. The warning listed both items, and only one of them was actually checked.
Deleting the two dead publish wrappers then revealed a second layer — publish_candidate_owned, remove_and_save_with, clear_and_save_with, save_tiering_config_if_current. These are not dead: publish_candidate, their caller, is #[cfg(test)], so a callee that lives in the main body has no caller in the lib build and a live one in the test build. rustc reports the roots of a dead subgraph, and the next layer down can have a different character, so each layer needs its own grep.
Kept with allows: the tier mutation-intent record helpers (asserted by store::init tests), affected_targets, tier_object_blocks_target_rebind, the rebalance snapshot and retry-wait helpers, notification_sys's tier_config_reload_worker_active and call_peer_with_timeout, and active_operation_lease_count, whose only caller sits behind #[cfg(feature = "test-util")].
Also kept, with a module note rather than removal: the ecstore-side EventNotifier. All four of its methods are unreachable and init_bucket_targets logs that it is a no-op in this build; the working stack is rustfs-notify, whose own EventNotifier drives bucket configuration. Removing it means also retiring the InstanceContext slot that holds it (backlog#939 Phase 5), which belongs in its own PR.
Worth a separate issue: MAX_MULTIPART_PUT_OBJECT_SIZE, MAX_PARTS_COUNT and MIN_PART_SIZE are declared independently in eight warm-backend files plus client/constants.rs. Only the GCS copies were dead; the other seven backends each use their own.

* chore(ecstore): remove the pool-level ListObjects pagination copy
The ListObjects pagination pipeline existed in three near-copies in one file; production listing never reaches the Sets copy, which ECStore bypasses by expanding straight to per-set disks. This removes it: impl ListOperations for Sets (61 lines of pure forwarding in core/sets.rs) and the impl Sets pagination block (826 lines of inner_list_objects_v2 / list_objects_generic / inner_list_object_versions / list_path / list_merged / walk_internal in store/list_objects.rs).
Two preconditions verified before deleting rather than taken on faith: the architecture guard pins only set_disks_implements_storage_list_operations_contract, so nothing requires the Sets trait impl; and the four Sets pagination methods had no cross-file caller besides that trait impl.
The single test consumer moves to the surviving pipeline instead of being deleted: writes still go through the pool, and the listing assertion now targets the set-level implementation. It is renamed accordingly so the name still describes what it covers.
The logging guardrail's TRACE-only requirement for Sets::list_objects_v2 retires in the same diff — the wrapper it pinned no longer exists. The ECStore and SetDisks entries are untouched.
The SetDisks copy stays for now: its trait impl is guard-pinned, so replacing the duplicate pipeline behind it needs the generic helper the issue schedules for post-1.0.
Verification: cargo nextest run -p rustfs-ecstore 4020 passed; check_architecture_migration_rules.sh and check_logging_guardrails.sh pass; clippy --lib --tests -D warnings clean; make pre-commit green.

* chore(ecstore): fold the ListObjects forwarders into the ECStore impl
store/list.rs held two thin forwarders, handle_list_objects_v2 and handle_list_object_versions, that only re-entered the inner_* implementations. The ListOperations impl now calls those directly and the file goes away.
The logging guardrail's trace_hot_spans list pinned handle_list_objects_v2 as TRACE-only; that entry is retired in the same diff, adjacent to the sets.rs entry retired by the preceding commit.
Ref rustfs/backlog#1821.
* chore(ecstore): drop the type aliases orphaned by the pagination removal
core/sets.rs declared four local type aliases — ListObjectsV2Info, ListObjectVersionsInfo, ObjectInfoOrErr and WalkOptions — used only by the pool-level pagination pipeline removed earlier in this branch. store/list_objects.rs keeps its own live copies of the same aliases.
They only surface now that #6087 removed the core module's dead_code blanket: on that older base each PR was warning-free on its own, and the combination is what exposes them. Their storage_api_contracts imports go with them.

* test(table-catalog): move the store-side stateful object backend into test_support
First half of the issue's PR2: the store tests' TestCatalogObjectBackend cluster (state/record/locks/pause types, the seed/fail/pause instrumented inherent impl, the TableCatalogObjectBackend trait impl, and the BlockingObjectPublication/UnserializedTestPublication commit-publication fakes — 544 lines) moves verbatim from table_catalog/tests.rs into test_support.rs, with pub(crate) visibility on the items and fields the tests reach directly. Pure move, no behavior change; the admin handler tests' TestTableCatalogObjectBackend union (its put barrier / fail-path / lock-attempt instrumentation folding into this fake) is the second half.
Verification: cargo test -p rustfs --lib table_catalog 481 passed; clippy --lib --tests -D warnings clean; make pre-commit green.
Ref rustfs/backlog#1837 (PR2, part 1).
* test(table-catalog): fold the admin object backend into the shared fake
Second half of PR2: the admin handler tests' TestTableCatalogObjectBackend (struct, inherent impl, trait impl, lock alias — 201 lines) is deleted and its instrumentation folded into the shared TestCatalogObjectBackend, which the admin tests now take through a type alias so no call site is renamed.
Two behavioral differences between the two fakes were found by the test suites rather than assumed away, and both are preserved:
- Lock observability: the admin fake implemented only acquire_write_lock, so the trait's default acquire_read_lock -> acquire_write_lock delegation made read acquisitions visible in lock_attempts. The shared fake implements both independently, so five fence/lock tests timed out until the read path also records attempts.
- Etag generation: the admin fake used content-addressed sha256 etags (its tests observe an etag and expect rewriting identical bytes to reproduce it) while the store fake uses an incrementing counter. Instead of silently picking one, the union carries a content_addressed_etags flag; the 80 admin construction sites go through TestCatalogObjectBackend::content_addressed() and the store tests keep counter semantics.
The six one-shot path-keyed injection knobs (fail/corrupt put, missing/fail read, put barrier) run before the store fake's attempt-indexed injection maps, matching each fake's original ordering.

Removing both blankets exposes 23 items, of which only four are deleted. The ratio is the point: close to the core data path the blankets were hiding test assertions and migration seams, not dead code.
A cfg-split function is the reason two symbols in the internode transport look dead when neither is. build_internode_data_transport_from_env has two bodies, one under #[cfg(test)] that calls build_internode_data_transport directly and one under #[cfg(not(test))] that goes through the INTERNODE_DATA_TRANSPORT static so tests do not share process-global transport state. Each half's helper is live in exactly one build, and because cargo check --tests compiles both the lib target and the test harness, both symbols appear in one warning list. Deleting either one breaks the other lane. Both are kept with allows naming their half.
Three deletion candidates were withdrawn after a per-name grep: ParallelReader::new, ErasureDecodeReader::new and SyncErasureDecodeReader::new all have test callers. The last two are exactly the shape of the dead wrapper deleted in #6084 — a thin forward to a new_with_metrics_path sibling — except that sibling is live in production (set_disk/read.rs) and the wrappers are used by tests.
Deleted:
- RemotePeerS3Client::get_addr and RemoteLocker::from_url, neither with a consumer in any lane.
- RemotePeerS3Client's node field, which new writes after using it to derive addr and nothing ever reads. Its only other writer was a test helper that built a whole Node solely to fill the field; that block goes too.
- ParallelReader::can_decode, superseded by an inlined copy. The copy's comment named the method it replaced, so deleting the method alone would have left a dangling reference; the comment now describes the check instead of pointing at a method that no longer exists.
Kept with allows: the erasure items are decode/encode invariants asserted by their own files' tests (shard_read_launch_order, decode_with_read_costs, emit_data_shards, queued_block_bytes, the engine trait facets, the ParallelReader and decode-reader constructors, encode_stream_callback_async). On the cluster side, peer_replay_state, heal_bucket_local and clone_drives are test-only, InternodeDataTransportCapabilities and tcp_http are constructed only by transport test doubles, and the InternodeDataTransport trait's name/capabilities pair is an unused capability-negotiation facet kept for the transport split (backlog#1350) — six impls provide them and no caller negotiates on them yet.
Verification, four lanes warning-free: default, --tests, --features rio-v2 --tests, --features test-util --tests. cargo nextest run -p rustfs-ecstore 4041 passed; clippy --lib --tests -D warnings clean; make pre-commit exit 0.

heal::Error carried six variants with zero construction and zero match sites (ConfigurationError, NotFound, TaskAlreadyExists, ManagerNotRunning, EventProcessingFailed, ProgressTrackingFailed) plus IO(String), which was never constructed either — its only appearances were two or-pattern match arms that could never fire (task.rs's demotion match and the recoverability classifier). All seven are deleted and the two or-patterns lose their dead alternative.
Config(String) stays (live, four construction sites); Io(std::io::Error) stays; the retry classifier's behavior is untouched per the issue constraint — removing an arm that can never match is not a classification change.

* refactor(sse): sink managed-SSE attribution into the shared encryption-keys module
Moves the managed-SSE classifier — stored_managed_encryption_key, contains_managed_encryption_metadata, normalize_managed_metadata — and the SSEType enum from rustfs/src/storage/sse.rs into crates/utils/src/http/object_encryption_keys.rs, the module that already owns every constant they read. This is PR-B0 of rustfs/backlog#1643: crates/scanner must never depend on the rustfs binary crate, so encryption attribution has to live in a shared lower layer before the scanner can report per-scheme coverage without growing a second classifier.
SSEType moves wholesale (option a): its only impl is the dependency-free audit_label(), so the enum relocates verbatim (audit_label becomes pub) and rustfs::storage::sse re-exports it, keeping every existing path compiling. The one piece that cannot move verbatim is normalize_managed_metadata's KMS-context branch, which needs base64 and serde_json — dependencies rustfs-utils does not have and does not gain here. The shared normalizer instead takes an injected Option<fn(&str) -> Option<String>> context recoder; sse.rs passes recode_minio_kms_context, the old inline chain verbatim including the silent skip on decode failure. stored_managed_encryption_key passes no recoder because the context mapping only ever inserts the context key, which the key-id lookup never reads, so its output is identical.
Every metadata lookup stays a case-sensitive exact match (lowercase x-amz-* stored forms, TitleCase MinIO-internal names) per the backlog#1775 trap; new shared-module tests pin that, and a source-scan test in sse.rs asserts the classifier has exactly one definition so a second copy cannot silently return.

* fix(kms): construct wrap_budget_reserved in the VaultKeyData deserializer
main does not compile: #6019 added VaultKeyData.wrap_budget_reserved on a base that predated #6003's hand-written Deserialize, so the visitor's struct literal never learned about the field. Each PR was green on its own base; the breakage only exists in their merge.
The field joins the other three lists the hand-written impl maintains (Field enum, match arm, struct literal, FIELDS) and defaults to 0 when absent — the value a record written before wrap accounting, or rewritten by an older build, carries; zero restarts the reservation rather than blocking a wrap.
vault_key_data_deserializer_covers_every_serialized_field turns this class of mistake into a test failure instead of a merge-order accident: it serializes a fully populated record and asserts the deserializer recognizes every emitted key (unknown-field counter stays zero) and reads every value back. Mutation-verified by dropping the new match arm.
* feat(kms): report a key as due for rotation once its wrap budget is spent
The rotation readiness verdict only knew about age; the wrap accounting landed by #6019 counted wraps and published an aggregate gauge but never fed the per-key verdict, leaving the criterion backlog#1636 asks for unimplemented.
RUSTFS_KMS_ROTATION_MAX_WRAPS adds the second, independent threshold, parsed with the same discipline as the age one: unset or unparsable leaves the verdict unreported rather than inventing a policy, and values below one million are raised to it because wraps are reserved in blocks of that size and a smaller threshold would trip on the first reservation regardless of how many wraps happened.
The wrap check runs before the age check so that a key crossing both reports 'wraps': the AES-GCM random-nonce ceiling is a cryptographic bound an operator cannot negotiate, while the age period is a policy they chose. Backends that report no count — Transit and AWS wrap externally, and pre-accounting records carry nothing — leave the wrap half silent instead of guessing, and a backend that cannot rotate is still never told to.

The two table_catalog test files (27.5K lines combined) each maintained a parallel constructor stack for Iceberg metadata JSON and avro manifest-list/manifest bytes. Per the issue's adversarial ruling the parameterized admin variants are canonical (the store file hardcoded sequence 7 / snapshot 20); the two stacks were verified structurally identical first — schemas byte-equal, field lists and values aligned.
New #[cfg(test)] table_catalog/test_support.rs owns the seven constructors (metadata JSON, three manifest-list variants, two manifest variants, nullable_long). The admin tests import them under their old names; the store tests keep their historical signatures as thin delegates passing the fixed values explicitly — every produced byte is identical to the pre-extraction fixtures (the delegate's argument order was cross-checked against the canonical destructuring after an initial swap surfaced as five sequence-bound validation failures).

Use BytesMut spare capacity for direct and pooled small PUT body reads while preserving exact-length validation.

RemoteAddr, the DependencyReadiness family (DependencyReadiness, ReadinessDegradedReason, DependencyReadinessReport), and convert_ecstore_object_info (with its offset_date_time_to_timestamp helper) are consumed across app, infra, and interface layers but lived under server, so every lower-layer import was an upward app->interface or infra->interface edge the layer guard had to baseline.
They now live in a new layer-neutral rustfs/src/shared_types.rs (classified infra by the guard, making all consumer imports downward or lateral). server::readiness and server::event re-export for their own internals; the eight consumer sites (admin_usecase, bucket_usecase, object_usecase, cluster_snapshot, storage/access, storage/helper, plus the admin handler tests) import from the new home. Pure move: no type, impl, or behavior change.
The regenerated layer-dependency baseline shrinks by exactly eight lines with zero additions — the ratchet's intended direction. The two remaining readiness entries (collect/snapshot fn imports) need the collection machinery itself extracted from server and are left for the issue's PR5 scope.
Ref rustfs/backlog#1834 (PR4).
The 14 tests carried #[ignore = "requires isolated global object layer state"], and the only CI lane that runs ignored tests filters for lifecycle tests — so they executed nowhere. Under nextest, the authoritative runner, every test owns its process and the stale reason no longer applies; all 14 pass.
Ten of them assert the InternalError path taken while the global object layer is uninitialized, a premise a sibling test can destroy under the documented shared-process cargo test fallback. Those ten now start with an explicit premise guard: when a sibling already initialized the store the test skips with a message instead of asserting against a scenario it does not describe. Under nextest the guard never fires and the assertions always run.
Dual-runner evidence: nextest 79 passed; cargo test module-scoped 79 passed; the full storage-tree cargo test sweep returns to its pre-existing baseline (8 unrelated in-process failures, none introduced or worsened here). No test deleted.
