* test(e2e): add scanner/heal topology protection matrix
Add the S00 protection baseline for the Scanner/Heal program
(rustfs/backlog#2873, program rustfs/backlog#2872): seven
scanner_heal_topology_ cases in the distributed e2e lane that pin pool
expansion, rebalance and decommission behavior before the runtime changes.
The fixture seeds a deterministic inventory (empty, inline, external,
multipart, special and nested keys; a versioned bucket with an explicit
null version, three history versions and a delete marker per key; an
Object Lock bucket with legal hold and COMPLIANCE retention), records
every version with its requested and listed version id, length and
SHA-256, verifies the manifest through every node, reads physical
placement from xl.meta on the pool drives, and reads the strict
durability mode back from the admin API and the node logs.
Fault cases hold the mover at proven windows through file barriers that
compile only with the e2e-test-hooks feature: before the multipart target
commit and before source cleanup (shared by decommission and rebalance),
plus the existing pool-metadata before_publish cutpoint. An unreached
window fails the case. DistCluster gains capture_logs_under so a case can
read node startup events without a global environment variable.
docs/testing/scanner-heal-topology-gates.md maps the gates to the tests
and records the timeout basis.
* test(e2e): keep the barrier failure message static
The error(format!) ratchet rejects new formatted io::Error::other call
sites in ecstore. The reached observation already records the stage and
object, so the injected failure needs no per-call detail.
* test(e2e): require e2e-test-hooks for topology fault cases
The four scanner_heal_topology_ fault cases inject at server barriers that
exist only with the e2e-test-hooks feature. Against a default server they
waited for the barrier timeout and reported it as not reached. Check the
verified binary's features first so the missing prerequisite fails
immediately and is named.
* ci(e2e): build the distributed lane with e2e-test-hooks
Every other e2e lane builds and runs the fault-test hooks server. The
distributed lane alone used the default server, so the topology fault
cases could never reach their barriers there. Build and run with the same
feature so the receipt matches, and update the documented local commands.
The upgrade cases spawn the pinned previous release directly and do not
compare feature sets.
* test(e2e): keep topology artifacts under RUSTFS_E2E_LOG_DIR
The topology fixture captured node logs, barrier observations and evidence
in a temp dir removed on drop, so the distributed workflow uploaded nothing
for these cases. Fall back to RUSTFS_E2E_LOG_DIR, which the workflow
uploads, when no explicit evidence directory is set.
* test(e2e): remove retired pools before restart; race the pre-ACK start
The queue case restarted with decommissioned pools 0 and 1 still on the
command line, which the server rightly refuses. Add
remove_single_node_pools and restart without them, then expect the
remaining pools renumbered to 0 and 1.
The pre-ACK case now races the start request against the barrier. A start
that returns first, or stays in flight past the documented 60 s budget, is
reported as such instead of as an unreached barrier, and the evidence
records the reach latency.
capture_logs_under now overrides a log path assigned from
RUSTFS_E2E_LOG_DIR, so the seed node logs into the case directory too.
* test(e2e): bound fault-window waits by the movement budget
On Linux CI a busy target capacity gate delayed the first fault object by
about two minutes, past the 120 s wait borrowed from the server's release
poll. Wait for a movement window within the 240 s movement budget instead,
and fail at once when the decommission or rebalance ends without entering
the window, so an uninjected fault is never counted.
* test(e2e): bound status probes while waiting for a fault window
The admin decommission status request can wait on a mover held at a test
barrier until the barrier's own 120 s release timeout. The window wait
issued that request each loop, so a reached barrier went unnoticed until
the server timed it out and failed the decommission, which surfaced as a
false resume failure. Bound each status probe to 5 s and treat a slow probe
as still running.
* test(e2e): retry a busy decommission start
A decommission start that meets a busy movement gate can answer a
retryable 503 instead of waiting. The harness treated any non-proof
failure as fatal. Share one start helper that retries 503 within the
case's movement budget and the fleet-proof 500 for 45 s, and keeps every
other status fatal. The pre-ACK case retries 503 within its window budget.
The scanner heal gate dropped Some(Uuid::nil()) along with None, so null versions in versioned buckets never reached existing-object replication. Skip only unversioned listings, matching MinIO, and recognize the nil UUID as the null version in the newer-target guard and version comparison.

A restarted node published FullReady from its own view while survivors still counted its drives unavailable (stale DNS for the old pod IP, then the Offline->Returning->Online hysteresis). A rolling update could then stop the next pod and cost a set its read quorum (#8669).
Add a read-only PeerDriveAdmission internode RPC that reports how a peer sees another host's drives, and gate the startup FullReady transition until a strict majority of each erasure set's peers count this node's drives online. The gate shares the startup budget, releases after 15s of unreachable peers, skips immediately when older peers cannot answer, and can be disabled with RUSTFS_STARTUP_PEER_READMISSION_ENABLE=false.

* feat(policy): support s3:if-none-match and s3:if-match condition keys
Bucket, IAM, and STS session policies that enforce conditional writes
with s3:if-none-match or s3:if-match were rejected with "invalid key
name". Accept both keys and populate them from the If-None-Match and
If-Match request headers. A blank header is left out of the condition
values because the write ignores it, so it cannot satisfy a Null check
for a write that runs unconditionally.
* fix(policy): classify conditional write keys as request-derived
s3:if-match and s3:if-none-match are filled from request headers, but
is_server_derived() reported them as server-derived because their names
lack the x-amz- prefix. Add an explicit arm so header input is never
refused for these keys if they join COMMON_KEYS.
* fix(s3): reject non-wildcard If-None-Match on writes
S3 accepts If-None-Match on PutObject, CopyObject and
CompleteMultipartUpload only as "*" and answers other values with 501
NotImplemented. RustFS compared such a value as an ETag, so a write with
If-None-Match: "<other etag>" overwrote the key while satisfying a
policy that requires s3:if-none-match.
Reject ETag values in the three handlers before any I/O. The store-level
check now treats any non-blank If-None-Match as create-only, so a caller
that skips the handler check cannot weaken the precondition. Drop the
CompleteMultipartUpload ETag pre-check that the rejection supersedes.
* test: tighten conditional write policy coverage
Pin trimming and the non-UTF-8 case in the condition values, and drop
the auth test that re-ran policy evaluation already covered by the
policy crate. Run the three policy e2e scenarios on one server, assert
that ETag If-None-Match cannot overwrite under a Null: false policy and
that CompleteMultipartUpload with If-None-Match: * returns 412. Share
the AssumeRole response parser through common.rs.

Reject single, batch, and exact-version deletes before staging mutations.
Transfer real lifecycle ownership through detached deletion and reuse the
cleaner's existing owner to avoid a queued-writer deadlock.
Correct the physical-tail cancellation observer and cover disconnected PUT
publication plus managed delete refusal with four-node tests.
Since 1.0.2 an encrypted object's ETag is a keyed fingerprint, not the
plaintext MD5. A target that computes its own ETag (AWS S3, Wasabi) never
reports it, so every "find the existing replica by exact ETag" step missed
encrypted objects on targets that mint their own version ids:
- a heal / MRF re-drive after a lost PUT response wrote a second version;
- an existing-object resync re-PUT a replica its ledger already named
(the ledger-located HEAD was confirmed by ETag only), and on the AWS
400 shape the ledger was not consulted at all;
- resync verification counted such replicas as failed;
- a ledger-less version purge reported the replica as already gone.
Encrypted sources now recognise their replica by shape: the byte count the
replication PUT sent (plaintext for managed SSE, ciphertext for SSE-C) and
a target write time no earlier than the source version. An ETag match
still wins (RustFS/MinIO targets). The ledger is consulted first on both
the 404 and the AWS 400 shape. Without a ledger, only a unique shape match
among the unclaimed ListObjectVersions candidates is adopted and recorded;
several shape matches mean re-PUT for convergence and a refused purge. The
AWS current-version fallback stays ETag-only, and a listing the
target refuses on the 400/403 shape keeps that fallback (re-PUT) rather
than stalling. An unversioned target's `null` version is never matched by
shape: it holds whichever generation was written last. Plaintext sources keep exact
ETag identity.
Builds on the ETag-computing fake target mode and the ComputesOwnEtags
matrix row from rustfs#8583. Adds an SSE-S3 variant of the mint-own-ids
re-drive test (red before this change: the heal left two target versions),
and both variants now also assert the purge.
Since #8535 DeleteObjects honours Quiet=true the way S3 does and omits the
successful entries from the response, so the quota batch-delete test has
been asserting two Deleted entries against an empty list on every main run.
The test only needs the batch to succeed and free quota; make it verbose so
the existing assertion holds and check that no entry failed.
