* fix(replication): tolerate orphaned resync intents at startup
Since #5215 (1.0.0-beta.12) startup reconciles every pending/started
resync intent in resync.bin against the bucket's configured targets and
aborts the whole server when an intent has no matching target ARN. A
resync whose remote target was later removed leaves exactly such an
orphan on disk, so every later start fails with "accepted replication
resync target ... is not configured" regardless of the binary version.
Skip orphaned intents with a warning instead of failing startup; the
resync routine already settles them to ResyncFailed. Cancel the intent
when its remote target is removed so the orphan is not created again.
Fixes#4784
* fix(replication): cancel removed-target resync under the admission lock
Canceling through this node's cached whole-bucket status map could
persist a map that predates another node's admission, erasing that
node's durable restart intent. Reload resync.bin under the bucket
admission lock, publish the fresh map, and only then mark the removed
target's intent canceled. Two-node regression covers the clobber.
* fix(replication): persist resync status via ETag CAS merge
mark_status, the periodic saver, admission, and removed-target
cancellation all persisted their node's cached whole-bucket map, so any
one node's stale cache could resurrect states another node had already
finalized (a canceled intent flipping back to Pending, an admission
vanishing). All resync.bin writers now go through update_resync_status_cas:
load the freshest document with its ETag, apply a per-target mutation
with staleness and canceled-is-terminal guards re-checked against the
persisted entry, and save conditionally, retrying on concurrent writes.
The periodic saver merges per target, letting terminal states and newer
admissions recorded elsewhere win. Cache convergence stays per-target so
locally running resyncs keep their authoritative progress counters.
Regressions: stale_peer_status_write_cannot_resurrect_canceled_intent
(node B's pre-cancel cache marking its own run Started must not revive
node A's canceled intent) plus unit coverage for the periodic-save merge.
* test(ecstore): rename resync test helper off the guarded contract name
fn resync_target is on the architecture guard's reserved list for
crates/replication operation contracts; the merge-test helper now reads
resync_target_state.
* fix(replication): serialize resync status updates

* fix(ecstore): persist unresolved decommission entries
* fix(ecstore): type decommission completion result
* fix(ecstore): allow intentional decommission listing signatures under strict clippy
The sftp/swift feature-matrix clippy gates run with -D warnings and
flag the unresolved-entry resolver (large Err payload by design, 8
context parameters) and the decommission listing driver (9 args).
Document why and align with the existing decommission_entry precedent.
fix(rustfs): drop sftp-dead scanner capability import and unwired heal_bucket trait method
The sftp feature matrix compiles fewer call sites: the plain
sign_ns_scanner_capability re-export had no remaining user, and
StoragePeerS3ClientExt::heal_bucket was superseded by
heal_bucket_with_fence when #6416 wired the fenced path.
cargo fmt --check has been failing since #6410 landed: the merged
decommission import groups in core/pools.rs were not canonical
rustfmt output. Apply formatting verbatim, no code changes.
Add a read-only Prometheus report helper for backlog#2007 so the 200us vs 50us coalescer delay experiment can capture RPC, batch distribution, stage latency, and host-cost signals with one fixed evidence format.

A single object's SourceChanged during decommission cleanup no longer
cancels the shared worker token and fails the whole pool operation.
Cleanup preflight and source-cleanup outcomes now retry per entry with
bounded attempts and cancellation-aware backoff, applied uniformly to
ordinary versions, delete markers, and tiered copies (removing the
try-once-only branches); every retry re-lists the entry and redoes
version multiset validation before touching the source. Only quorum
loss, unrecoverable system errors, or exceeding a pool-level
SourceChanged exhaustion threshold still fails the decommission, and
exhausted entries never delete their source versions.
Retry attempts, backoff, and deferred/exhausted reasons are logged per
entry for observability. Heavy regression tests spawn on dedicated
32MiB stacks following the existing store-test pattern.
