Chris LuandDevin 379abbe278 volume: repair torn tails on canDelete volumes; reject damaged 1-3 byte records (#11876)
- Go/Rust: run the unindexed .dat tail repair on noWriteCanDelete volumes
  too — deletes still append tombstone records, so the same crash window
  applies and they previously degraded to fully read-only.
- Go readTailNeedle: reject a positive size of 1-3 for v2+ as corrupted
  before ReadBytes slices the body's 4-byte data-size field and panics;
  a torn last record is now cut instead of crashing the load.
- Tests: TestVolumeLoadRepairsTailOnCanDeleteVolume and
  TestVolumeLoadCutsDamagedSmallSizeTailOnCanDeleteVolume (Go), and the
  Rust mirrors volume_load_repairs_tail_on_can_delete_volume /
  volume_load_cuts_damaged_small_size_tail.

Chris LuandDevin ab738bfd33 rust volume: repair an unindexed .dat tail at load (#11878)
* rust volume: repair an unindexed .dat tail at load

Mirror Go's repairUnindexedDatTail (#11870): a crash between the .dat\nappend and the .idx append leaves a .dat tail no index entry covers,\nwhich sent the volume read-only on the next load and left acknowledged\nneedles unreadable. Before the index loads, re-index the complete\nneedles in the tail (a size 0 record as the tombstone or empty write\nresolveEmptyTailRecords reads it as) and cut only an incomplete last\nrecord. A tail an interrupted append does not explain is left as it is\nand the integrity check quarantines the volume read-only as before.

* rust volume: tests for the unindexed .dat tail repair

Reload volumes through the real load path after dropping .idx entries\nand cutting or damaging the .dat, mirroring Go's\nvolume_checking_tail_repair_test.go: complete unindexed needles are\nre-indexed (deletes as tombstones, empty writes as empty needles), an\nincomplete last record is cut, and a tail an interrupted append does\nnot explain is left untouched with the volume read-only.

* volume: re-index a torn size 0 record as a live empty needle

A delete and a write with no data append the identical size 0 record, so a
recovered one cannot be told apart from the prior index state alone: the
write path accepts an empty overwrite of a live key and indexes it with
size 0, while a delete of the same key publishes a tombstone. Inferring a
tombstone from prior live state turned a lost index row after an empty
overwrite into a deletion -- the object read back not-found although the
write was answered.

Every re-indexed record is now indexed at its on-disk size, the entry
publishWriteRequest writes for an empty write. The other misread is
bounded: a recovered delete reads its key back as an empty object rather
than not-found, and the size 0 record carries no data to resurrect.

Review feedback on the Rust mirror (#11878): the same bug exists here;
fixing both sides identically.

* rust volume: re-index a torn size 0 record as a live empty needle

Mirrors the Go fix in this pull request. A delete and a write with no data
append the identical size 0 record, so resolve_empty_tail_records could
not tell them apart from the prior index state: it treated a zero-size
record of a live id as a tombstone, although the write path indexes the
same bytes as a live size 0 entry. A crash after an empty overwrite of a
live key therefore recovered the object as deleted.

Every re-indexed record is now indexed at its on-disk size, the entry
publish_write writes for an empty write. A recovered delete reads its key
back as an empty object rather than not-found; the size 0 record carries
no data to resurrect.

* volume: repair a .dat tail left past an empty .idx

The writable index loader creates the .idx before the first needle append,
so a crash after that append leaves a volume whose data nothing indexes.
CheckVolumeDataIntegrity skipped an empty index outright, so the volume
loaded writable and the surviving first needle stayed invisible while
later writes appended past it.

A zero-size index now runs the same repair with tailEntryPos -1: the walk
starts at the first record past the superblock with no anchor needle and
no append timestamp to compare against, gets the same complete-record
validation and incomplete-tail policy, and re-verifies through the normal
tail check once it wrote entries. A tail the repair cannot explain fails
the check, so the volume loads read-only instead of writable on an
unaccounted-for .dat.

* iceberg maintenance: compare parquet schemas by field id in bin-pack merge

parquet.EqualNodes ignores Iceberg field ids, so a column dropped and\nre-added under the same name and type compared equal and was merged,\nfiling the new column's values under the dropped field id.

A bin used to take the first file's Parquet schema as the writer's and\nrefuse every file that was not structurally identical, so a table never\ncompacted once files had a different column set or REQUIRED-vs-OPTIONAL\nrepetition. A file whose flat columns the writer's schema covers by\nfield id is converted into it (a column the file lacks reads as null);\na file that covers the writer's schema restarts the bin with it, so no\ncolumn is dropped. Equality-delete columns resolve on each file's own\nschema. Renames, type changes, nested columns and files without field\nids stay refused.

Chris Lu a724f4296c s3, s3tables: create buckets and namespaces exclusively (#11872)
* filer_pb: add MkdirExclusive

A taken name leaves the callback as a result, not an error, so filer
failover does not count a lost race as a filer failure.

* s3tables: create the entry with its attributes in one exclusive create

CreateTableBucket and CreateNamespace checked that the name was free and
then wrote the entry in several calls, so a second create in the window
replaced the first caller's entry including its owner. The create now
carries the marker, metadata and tags in one O_EXCL CreateEntry that
answers ErrEntryAlreadyExists with the same 409.

* s3: PutBucket uses an exclusive mkdir

The same window let a plain PutBucket replace a table bucket created
concurrently. The already-exists branch now answers from the entry itself,
since the registry just cached the name as absent, and the admin
auto-create path is exclusive too.

* s3: read the winning entry when a create loses the race

The concurrent-create branch called existingBucketError on a name the
registry had just cached as absent, answering NoSuchBucket, and the
auto-create fallback could assign an S3 owner to a table bucket it met
there. The negative cache is cleared before the existing-bucket error is
built, and a table bucket keeps its owner-less shape.

* s3: fail an auto-create that met a table bucket

A table bucket carries no S3 owner and must not gain one, and the upload
that auto-create ran for must not continue into it either.

* s3: fail an auto-create when the winning entry cannot be read

An unreadable existing entry fell through to success, so the write
continued into an unvalidated entry, possibly a table bucket.

Chris Lu f05d743459 s3: resolve versionId tagging requests to the version-tagging actions (#11874)
* s3: resolve versionId tagging requests to the version-tagging actions

A request for an object's tags with versionId acted on a historical
version but authorized against the current-object tagging action, so an
explicit Deny on s3:*ObjectVersionTagging never applied.

* iam: map PutObjectVersionTagging and DeleteObjectVersionTagging to the tagging action

* s3: only resolve tagging when the query value is empty

The tagging routes match ?tagging with an empty value, so a non-empty one
is not a tagging request and would resolve a tagging grant onto the plain
read or version read that actually serves it.

* s3: keep resolving tagging for any query value

The routes match ?tagging whenever the key is present, so tagging=x is a
tagging request served by the tagging handlers and must resolve to the
tagging actions.

Chris Lu 03a75cbc52 s3tables: only the admin repairs a table bucket that has no owner metadata (#11873)
* s3tables: only the admin repairs a table bucket that has no owner metadata

CreateNamespace wrote bucket metadata naming the caller as owner before any
permission check ran, so an ordinary caller that found the marker without
metadata was written in as the bucket's owner and passed every check after.
A bucket in that state is answered with the operation's own denial; the
admin or a trusted internal handler may still repair it.

* s3tables: repair the marker-only bucket under the entry lock

A creator finishing its own create between the missing-metadata check and
the repair write would have its owner overwritten. The mutation now adopts
whatever metadata is there and writes only while it is still absent.

* s3tables: gate the repair on the Admin action, not an operation grant

hasAdminAction also answers s3tables:*, so a non-admin identity holding
the wildcard operation grant could pass the repair check and write itself
in as the bucket's owner.

* s3api: persist single-identity IAM changes through the credential manager

CreateAccessKey, DeleteAccessKey, UpdateAccessKey, PutUserPolicy, DeleteUserPolicy, SetUserStatus, UpdateUser and DeleteUser used to load the whole configuration, change one identity and then SaveConfiguration, rewriting and re-propagating every identity. They now write only the identity (and, for rename/delete, the groups and service accounts that referenced it) through the credential manager, which propagates that identity alone. Static identities and skipPersist keep the previous full-save/no-write contract.

Javier de la TorreandJavier de la Torre df89afbef4 volume: repair an unindexed .dat tail at load instead of loading read-only (#11870)
* volume: repair an unindexed .dat tail at load instead of loading read-only

A needle write appends the needle to the .dat, then its entry to the .idx,
then answers the client. A crash between the two appends leaves a .dat that
ends past the last indexed needle; on the next start CheckVolumeDataIntegrity
reports "actual N bytes expected M bytes" and the volume loads read-only, and
a complete needle in that tail cannot be read because nothing indexes it.
After a process crash those bytes belong to a write that was never answered;
after a power loss a complete needle can survive in the .dat while its .idx
entry did not, although the client was answered. So complete needles are
re-indexed rather than cut.

CheckVolumeDataIntegrity now repairs the tail before the existing check,
which then runs on the repaired files as before. The repair:

- acts only on a local, version 3 volume within MaxPossibleVolumeSize, with a
  whole number of .idx entries, that is about to load writable (neither
  noWriteOrDelete nor noWriteCanDelete is set);
- requires the needle at the highest indexed offset to match its entry (id,
  size, whole record, CRC);
- walks from the end of that needle to the real end of the file and gives
  every complete needle (header, body, checksum, timestamp and padding inside
  the file, CRC valid, append timestamp later than the needle before it) the
  .idx entry the volume server would have written, in .dat order; a size 0
  record, which is how a delete is appended, is indexed as a tombstone;
- cuts only an incomplete last record: fewer bytes than a header, a record
  running past the end of the file, or a last record whose CRC fails;
- changes nothing otherwise (a damaged record with more data after it, a
  header with id 0 or a negative size, append timestamps going backwards), so
  the volume loads read-only exactly as before.

The .idx entries are written and synced before the .dat is truncated and
synced, so a crash during the repair leaves the needles indexed and the
remainder still past them; the next load cuts it. One warning per repaired
volume names the needles re-indexed and the bytes cut.

Tests: volume_checking_tail_repair_test.go reloads volumes through the normal
load path. Repaired: one and two complete unindexed needles, an unindexed
delete, a partial header, a partial body, a complete needle followed by a
partial one, a last needle with a bad CRC, a partial needle after an indexed
tombstone; each reloads clean afterwards. Left read-only and unchanged: the
last indexed needle with a wrong id or a bad CRC, a bad CRC followed by more
data, zero bytes past the last needle, an index past the data, a volume
persisted read-only, a partial .idx entry, and a clean volume.
TestCheckVolumeDataIntegrityVerifiesDeletionTail now also checks that on a
writable volume its 64 zero bytes are reported and kept.

Fixes #11864

* volume: fail the integrity check when a tail repair cannot complete

A repair that wrote the .idx or cut the .dat and then failed to sync only
logged the error; the check that followed saw the repaired files and the
volume loaded writable on a repair that may not be on disk. Any repair
error other than an unexplained tail now fails the check, so the volume
loads read-only, and the next load repairs again.

A failed .idx append could leave part of an entry behind, which made every
later load reject the .idx as a partial entry. The appended bytes are
truncated away again before the error is returned.

* volume: do not cut a tail record that could not be read

The walk cut a last record whose read failed for any reason, so an I/O
error (EIO) on a complete record erased it. Only a record whose bytes are
damaged (needle.ErrorCorrupted: a CRC mismatch or a body that does not
parse) is cut now; any other read error is returned with both files left
as they are, and the volume loads read-only.

* volume: treat a sized tail record with no data as damaged

A needle with no data is written with size 0. A tail record whose header
gives a body but whose data size field reads 0 parsed as an empty needle,
and ReadBytes checks the CRC only when there is data, so the repair indexed
it with its positive size and reads returned an empty body. Such a record
is now damaged like one with a bad CRC: cut when it is the last record,
otherwise the tail is left alone and the volume loads read-only.

* volume: keep an unindexed empty write as an empty needle

A delete and a write with no data both append a size 0 record, and the
repair indexed every size 0 record in the tail as a tombstone, so an
acknowledged empty write whose .idx entry was lost read back as deleted.
A delete is only appended for a needle that is live, so a size 0 record
of a needle that is absent or deleted (in the .idx and in the tail before
it) is an empty write and is re-indexed with size 0. One of a live needle
stays a tombstone, the reading weed fix and the backup's index
regeneration already give it. The .idx is scanned only when the tail holds
a size 0 record.

* volume: cut torn-tail test records inside their body, not at +40

The partial-record cases cut the .dat 40 bytes into a record. A needle
with up to 7 bytes of data is a 40-byte record, so newRandomNeedle's
random length (1..1023) left it whole about once in 150 runs per case:
the repair then correctly re-indexed it and cut nothing, and the test
failed on the .dat size. The cut now lands halfway through the record's
body, which is always past its header and short of its end.

Chris LuandDevin 1cfd9bbb4c volume: run the durable sync outside the reader-visible lock (#11863)
* volume: run the durable sync outside the reader-visible lock

Reads of a volume waited on that volume's fsync because the write lock
was held across Sync()/sync_all. A new per-volume lock (Go
dataFileSyncLock, Rust data_file_sync_lock) now serializes every .dat
mutation and lifecycle op across append+publish+sync+rollback, while the
fsync itself runs with dataFileAccessLock/the io write guard dropped —
so readers proceed during a sync, and a failed sync's rollback still
cannot clobber another write or a compaction swap.

Same change in Go (volume_write.go syncWrite/processBatch, SyncToDisk)
and Rust (write_needles_grouped/write_synced_run).

* volume: publish after sync; fix Close/CommitCompact lock order

Address review on #11863:

- Close took dataFileSyncLock before waiting on isCompactionInProgress
  while CommitCompact claims the flag then takes the lock — a deadlock.
  Close now claims the flag before taking the locks (flag -> sync -> access).

- Go now publishes needle-map entries only after the .dat sync, matching
  Rust's ordering: appendWriteRequest/appendDeleteRequest stage the bytes,
  publishWriteRequest/publishDeleteRequest index them after Sync. A failed
  sync rolls back bytes no reader ever resolved — the streamed-read
  offset-invalidation window is gone. processBatch splits runs at repeated
  needle ids (Rust parity) so dedup/cookie checks stay sequential; the old
  snapshot/restore rollback machinery is removed.

- Rust commit_compact (store-lock caller) takes data_file_sync_lock via
  try_lock -> WouldBlock before the write lease; commit_compact_held and
  the tier-down _held paths document/require the caller-held sync lock,
  and the two vol.instance().write_lock() grpc sites take it first. The
  swap can no longer land between a durable write's append and publish.

* s3: mask anonymous misses behind AccessDenied unless the bucket is listable

Deferred anonymous GET/HEAD authorization only runs once an entry is

unauthenticated existence oracle for bucket names and object keys.

Route not-found responses in Get/HeadObjectHandler through a check that
only discloses 404 when anonymous listing is allowed (policy, identity or
a public-read bucket); otherwise the miss is indistinguishable from a
denied read, matching AWS and 4.48 behavior.

* s3: check a fixed request shape when masking anonymous misses

The miss check passed the caller's request through, so query parameters

fixed shape: a ListBucket scoped to the probed key and a plain read of the
key, so the miss only shows when the caller could learn the same fact
directly.

* s3: mask conditional-header misses for anonymous reads

An If-Match conditional on a missing key wrote NoSuchKey directly from
processConditionalHeaders, before the handlers reached the masked miss
path, so anonymous callers could still distinguish a missing key from a
denied read.

* s3: keep the versionId when masking anonymous misses

The read leg must evaluate the action the caller's request resolves to:
a versioned miss is s3:GetObjectVersion, and dropping versionId would let a
plain GetObject grant disclose versions the caller may not read.

Chris Lu 4d06742664 Detect and quarantine duplicate volume ids (#11763) (#11828)
* master: detect and quarantine duplicate volume ids across layouts (#11763)

* shell: volume.check.duplicate_ids audit command (#11763)

* master: persist duplicate-vid quarantine across heartbeats (#11763)

* master: quarantine all copies of a duplicated volume id

Near-simultaneous registrations let each side quarantine only the other,
so arrival order decided which copy stayed writable. A confirmed
cross-layout collision means either copy could be the impostor, so flag
every colliding copy read-only regardless of registration order.

* topology: return a copy from VolumeLayout.Lookup

Callers iterating the returned slice raced with registrations and
removals replacing the location list in place.

* master: release duplicate-vid quarantine when the conflict resolves

A cross-node volume.move briefly shows the same id on two nodes under
different disk layouts; permanent quarantine would pin a valid target
read-only. Keep the first-reported state per quarantined copy and lift
the marks once the conflicting copy unregisters, so only a persistent
collision stays read-only.

* shell: include ec shards in volume.check.duplicate_ids

Ec-only volumes share the global id space. Compare shard collections
against regular ones while allowing shards and regular copies of the
same encoded volume.

* master: keep quarantine release current and cover all removal paths

Track the latest server-reported read-only flag while quarantined so a
release restores the server s true state, and run the release check on
collection deletion and data-node removal too, not only explicit volume
unregistration.

* shell: do not flag ec-only volumes as duplicates

An ec-only volume has no regular copy, so its shard collections had
nothing to compare against and always read as foreign.

* master: quarantine every conflicting layout at the layout level (#11763)

- collect all conflicting layouts, not just the first, so a vid spanning
  three layouts does not leave one writable
- mark quarantine on the location list only: folding it into the stored
  report made the volume digest permanently disagree with the server and
  forced a full volume list every heartbeat
- isAllWritable now honors the location read-only mark so a quarantined
  copy stays out of writables through resyncs and re-registration
- re-check the conflict before keeping marks, and do not clear a node's
  quarantine while it still holds the vid in another layout
- log the full layout keys on both sides of the conflict

* master: push duplicate-vid quarantine to the volume server (#11763)

A quarantined copy stayed writable on the volume server itself for a
client holding an existing file id, since the master-only mark never
reached the server's local write path. Quarantine now also calls
VolumeMarkReadonly (can_delete so expiry still drains), is re-pushed if
the server comes back reporting it writable, and VolumeMarkWritable
runs when the conflict resolves and the server had reported writable.

* master: retry unenforced quarantine marks and restore server writability on release (#11763)

Dial the advertised grpc port, return mark errors, and keep a
quarantine entry until the writable push succeeds so a released
copy does not stay read-only on the server.

* master: treat rp-only layout differences as an in-flight replication change (#11763)

volume.configure.replication rolls through nodes one at a time, so a
volume legitimately reports the old and new replica placement while it
settles. Layouts differing only in rp within the same collection are a
supported transition, not a reused id.

* shell: group ec shards by collection in the duplicate id audit (#11763)

EC shards of one volume legitimately span disk types when
DiskTypePrefer spills, so grouping by disk type reports healthy
volumes as duplicates.

* s3tables: share the UpdateTable authorization gate

Extract the validation, load, and permission check from handleUpdateTable
into authorizeUpdateTable so the table an update was authorized against is
the same snapshot the mutation writes to. Manager gains
AuthorizeUpdateTable, mirroring AuthorizeCreateTable, so callers can ask the
question without updating anything.

* s3tables: share the UpdateView authorization gate

Extract the lookup, policy load, and permission check from handleUpdateView
into authorizeUpdateView, mirroring authorizeUpdateTable, and expose it as
Manager.AuthorizeUpdateView for callers that need the answer without the
update.

* s3api: scope vended table credentials to read-only on request

VendTableCredentials takes a readOnly flag and tablePrefixSessionPolicy
emits only s3:GetObject for the table prefix when it is set, keeping the
conditioned ListBucket and unconditioned GetBucketLocation statements that
reads still need.

* iceberg: vend read-only credentials when the caller may not write

LoadTable and friends vend storage credentials only for the authority the
caller holds: the vend now checks UpdateTable/UpdateView permission and a
caller that may only read the catalog entry gets a read-only session. Paths
that just passed a write gate (stage-create, view commit) keep the full
session.

* lance: vend read-only credentials when the caller may not write

storage_options vends the same read-only session as the Iceberg catalog
when the caller lacks UpdateTable on the table.

* lance: keep write credentials for callers authorized to declare

A Lance commit is a direct S3 write that never revisits the catalog, so a
caller that just passed CreateTable still gets a writable session; the
UpdateTable gate applies to describe, the read path.

* s3: list keys in byte order around directory markers

* s3: order deferred dir blocks by slash name and hold quota

* s3: fix deferred dir blocks at page and marker boundaries

Review follow-ups on the marker byte-order change:

- A marker inside an emitted "<name>/" block re-descended and re-listed its
  folded contents under delimiter "/" instead of skipping the block.
- A prefix object's "<name>/" common prefix was emitted eagerly at the name
  position, outranking siblings like "a.txt" and repeating across pages; the
  plain key now emits alone at the name position and the block emits the
  common prefix when children exist.
- A recursion starved on quota before listing a deferred subtree returned
  without truncation, dropping keys silently; the block now reports a
  resumable truncation when the subtree still holds entries.
- Clone prefix-object entries with proto.Clone rather than copying the
  protobuf message by value.

* s3: close the hasEntries probe stream on return

* s3: resume delimited listings at the dir block boundary

A deferred directory block emits at its "<name>/" position, but emitDir
left nextMarker at the bare name, which sorts inside the (name, name/)
band and reads as "block pending". Every pass of the listing loop then
re-emitted the same common prefix until maxKeys ran out (999 prefixes,
IsTruncated), and a "<name>/" continuation token trimmed to "<name>" by
adjustMarkerForDelimiter reopened the block and paged forever.

Advance nextMarker to the block boundary the same way the recursive
branch does, and keep a "/" -ending marker intact — it already names the
bound past the block.

Chris Lu 6b6a268903 volume balance: stop replica-fallback moves between equally full servers (#11851)
* volume balance: unify the per-move convergence guard

Evaluate the post-move utilization comparison through serverUtilization so
the guard also applies when servers lack MaxVolumeCount info (raw-count
mode), where it previously did not run at all.

* volume balance: restrict fallback destinations to improving servers

The score-based fallback inside createBalanceTask could redirect a move to
any valid server, including ones as full as the source — between equally
full servers the move only relocates the imbalance and the next detection
cycle reverses it (#11839). Exclude from eligibleTargets any server whose
post-move utilization would exceed the source's, so a fallback destination
satisfies the same convergence guard as the loop-chosen target.

* volume balance: skip a volume when the chosen target violates placement

When the detection loop's target resolves but cannot host the replica (it
already holds one, or is out of the filtered scope), createBalanceTask now
returns nil so the loop advances to the next volume — matching shell
volume.balance, which continues to the next candidate instead of
redirecting the move to a different server.

The score-based fallback is kept for the case where the target cannot be
resolved at all; its allowed set is already limited to servers the move
would improve.

* volume balance: regression test for replica-constrained targets (#11839)

Reproduces the reported loop: the emptiest server holds the second rp=001
replica of the lowest-ID volumes on the fuller servers, so it is never a
legal target for them. Detection must skip those volumes and send the
movable ones to the under-utilized server, and re-running detection after
applying the plan must never move the same volume twice.

Chris Lu 0fb6c0e77d filer.sync: unstick sync on chunks the source no longer has (#11845)
* filer.sync: keep the needle-404 clock from resetting on live volumes

The give-up clock for a source chunk that cannot be produced is kept per
volume so a vacuumed volume's files all inherit one wait. But a needle
404 and a volume lookup failure shared that clock, and sourceServed
cleared it whenever any needle on the same volume read fine, so on a
busy cluster the grace never elapsed for a single deleted needle on a
healthy volume and filer.sync retried it forever (#11841).

Give needle not-found answers their own per-volume clock that serving
siblings does not reset.

* filer.sync: an answered 404 needs no liveness probe before skipping

After the missing-chunk gate gives up, onReplicateChunkError only skips
the entry when a re-read of the most recently served chunk succeeds.
That probe can never have been armed on a fresh sync, and its single
stored file id can itself be vacuumed since — either way the entry stays
pinned and the offset never advances.

A needle 404 was answered by a live volume server, which is itself proof
the source is serving requests, so skip on it directly. Keep the probe
for the lookup-failure flavor, where no server answered and the silence
can still mean a source outage.

* filer.sync: skip a replayed version the source rewrote in place

Supersession was decided by entry mtime alone, so a source entry whose
chunks were swapped without an mtime bump — remote cache eviction and
re-cache, an in-place repair — never read as superseded, and its
vacuumed chunks were retried indefinitely.

When a chunk is missing, compare the replayed chunk's file id against
the live entry's resolved chunk set: absent means the replayed version
is obsolete and its event is skipped on the first failure instead of
after the give-up window. The same live-entry comparison now also
decides the entry-level skip in onCorruptChunk/onReplicateChunkError.

* filer.sync: give each missing needle its own grace clock

A 404 is one needle's answer, but the clock was kept per volume: once the
first needle's wait expired, every other needle on that volume inherited an
already-elapsed clock and could be written off on its first sighting. Track
the wait per file id and clear it only when that needle itself serves again,
so a live volume's healthy needles neither shorten nor restart it.

* filer.sync: keep the probe for filer-proxied 404s

ReadPart proxied through the source filer collapses "no volume locations"
into the same 404 a missing needle returns, so that answer cannot stand in
for the liveness probe the way a direct volume read's can. Only treat 404 as
an answered needle when the sink reads volume servers directly.

* filer.sync: only a not-older live entry can supersede a replay

Chunk-list comparison must respect the same ordering the mtime check does:
a live entry older than the replayed version means the source was rolled
back, so its differing chunks say nothing about whether the replayed data
is still needed. Gate the content check on live mtime >= replayed mtime in
both sourceMovedOn and sourceDroppedChunk.

* filer.sync: compare chunk ids without resolving manifests

resolvedChunkFileIds downloaded manifest files to expand chunk lists, so a
manifest sitting on a dead volume made the supersession check itself fail
and left the offset pinned behind a replica the source cannot read. File
ids are immutable needle identities — the unresolved sets already compare
chunk content exactly, and the check no longer performs I/O.

* filer.sync: judge nested chunks by their top-level chunk

A manifest child is not in the entry's chunk list even when the manifest
still references it, so checking the live entry for the child id reported
it dropped and returned the raw 404 — unwrapped, so the offset still
pinned. Thread the entry-level chunk id down the manifest recursion and
consult it for the dropped-chunk check instead.

* filer.sync: let the manifest-child test exit through the gate

Run the worker with a shortened grace period and assert the returned error
is marked errSourceChunkMissing, instead of racing the worker still running
against a restored RetryWaitTime.

Chris Lu 4feb30deff Federated volume-id bound via heartbeat stamps (#11763) (#11819)
* pb: heartbeat fields for the federated volume-id bound (#11763)

Heartbeat carries max_volume_id_seen and last_seen_topology_id up, and
HeartbeatResponse echoes max_volume_id and topology_id down, so the
allocation bound is replicated to every volume server.

* master: echo the volume-id bound and fold reported bounds in (#11763)

Every heartbeat response carries the leader current max volume id and
topology id; every heartbeat reported max_volume_id_seen is folded into
the topology bound via UpAdjustMaxVolumeId.

* volume: persist a per-dir vid stamp of the highest id ever seen (#11763)

The store keeps max_volume_id_seen + last_seen_topology_id in a
.vid_stamp file per volume dir, fed by heartbeat echoes, AllocateVolume,
and local volume/EC creation, seeded at boot from stamps and local
holdings, and reported in every heartbeat. A rebuilt master recovers
the bound from the first surviving veteran report.

* volume-rust: mirror the vid stamp and heartbeat echo handling (#11763)

Same mechanism as the Go volume server: .vid_stamp per dir, bound folded
in from add_location scans and allocate/mount calls, echoed fields
applied on heartbeat responses, reported on every heartbeat.

* volume: serialize vid stamp writes and fsync the directory (#11763)

* volume-rust: serialize vid stamp writes and fsync the directory (#11763)

* master: echo the allocation bound to connected servers on change

The bound was only sent at connect time or on digest mismatch, so a
healthy stream never learned later increases. If the high-id server then
went offline and the master lost state, survivors restored a stale bound
and the id could be reissued. Resend the heartbeat response whenever the
bound or topology id moved.

* volume: retry failed vid stamp saves on later updates

A transient write failure left the in-memory bound raised but the stamp
stale, and repeat updates at the same bound never retried. Track a dirty
flag so any later update re-attempts the save.

* volume: cover stamp bootstrap for pre-stamp dirs in test

* volume-rust: retry failed vid stamp saves, mirroring Go

* volume-rust: stamp every dir with the combined bound on add_location

A dir whose own stamp sat below the combined bound kept its stale value

The allocation bound lived only in raft state, so a master that lost it

reissue ids held by offline servers.

NextVolumeId now persists the bound to <mdir>/max_volume_id before the
raft apply, and both raft implementations persist on apply and recovery
so follower mirrors stay current. The file also carries the topology id,
which survives raft state cleanup the same way the snapshot recovery did.

Chris Lu ab559bca76 storage: hash index-metric bloom filter with xxhash
The reverse index walk dedupes seen NeedleIds with a BoomFilters bloom
filter. Its default kernel is FNV-1, whose final step only XORs the last
input byte into the hash's low bits, so keys sharing the high 7 bytes of
a big-endian NeedleId land on correlated probe positions and false
positives arrive in bursts of hundreds instead of the ~0.001 target
rate. Each false positive hides a live-latest key and inflates the
rebuilt deletion counters, which is what made
TestFastLoadingNeedleMapMetrics flake past its +256 bound in CI
(observed DeletedCount drift of 267).

Swap the kernel for xxhash, which fully diffuses the key bytes; the
observed false-positive count in 300 local runs of the test drops to
max 2 (avg 0.23).

callers already holding the lock, matching the existing Locked pattern.

The worker task lost its worker-host source preference when the idx gate
replaced the replica union. Late-bind the source to a replica on the
worker host using only the checked location set, with no FileCount
rebinding. Drop the now-unused helpers, trim comments added by the
earlier commits, and rename tests whose names still claimed convergence
while asserting refusal.

Chris Lu 8ac5133abe admin: default to port 12535, keep 23646 as a best-effort compat listener (#11816)
* admin: default to port 12535, keep 23646 as a best-effort compat listener

The default admin HTTP port 23646 derives a worker gRPC port of 33646
(port + GrpcPortOffset), inside the Linux default ephemeral range
(32768+). One of our own startup dials can claim 33646 before the admin
binds it, killing startup. This is the same failure #10209 fixed for
the test port allocator, still reachable via the mini default (#10838)
and via standalone `weed admin` defaults.

Move the default admin port to 12535 (gRPC 22535) everywhere, keeping
the http+10000 convention so worker -admin derivation, the Rust worker
and host:http.grpc addressing keep working:

- weed admin -port, weed mini -admin.port
- weed worker -admin, the plugin worker fallback, Rust worker and
  weed-lance-worker defaults
- help text, README, helm values, docker compose, tests

So old workers, bookmarks and scripts keep working, admin also serves
the same handler and the worker gRPC server on the previous default
(-port.legacy / -admin.port.legacy, default 23646, 0 disables). The
legacy gRPC port binds best-effort: it lives in the ephemeral range, so
a failed bind only warns instead of reintroducing the startup failure.
weed mini reserves it early like the primary port and keeps it out of
its own port relocation. grpc.Server tracks every listener handed to
Serve, so the compat listener stops with the primary.

Also warn when an explicitly configured admin port puts the derived
gRPC port at or above the ephemeral floor, the other fix suggested in
the issue.

Supersedes the pinned-grpc approach in #11814: pinning -admin.port.grpc
off the +10000 convention breaks external workers that derive the admin
gRPC port from the HTTP address. ClickHouse/ClickHouse#115512 pins
-admin.port on their side; this makes that pin unnecessary.

Fixes #10838

* admin: let services win the legacy ports, close compat listener on failure

Review findings on the compat listeners:

- Do not put the legacy ports in mini's reservedPorts: an explicit
  -s3.port=23646 or -master.port.grpc=33646 must be honored, not rejected
  or stolen by the early reservation. Mini now checks the finalized port
  set and skips only the conflicting compat listener, so HTTP and gRPC
  compat degrade independently and the service keeps its port.
- Also skip the legacy HTTP listener when a mini service owns the port:
  a wildcard-bound service can still leave loopback bindable, which would
  let the compat listener shadow it for loopback clients.
- Close legacyServer's raw listener in the deferred cleanup: Serve may
  not have registered it yet when startAdminServer returns early.
- Helm: add admin.legacyPort (default 23646) and expose the legacy
  http/grpc ports through the admin Service, container ports and
  NetworkPolicy so older workers resolved via the Service keep working.

* helm: only pass -port.legacy when it differs from the binary default

ct install deploys the released image with the new chart, and 4.48 does
not know -port.legacy, so the admin pod crash-loops. Omitting the flag at
the default value is behavior-identical on new binaries (their default
is also 23646) and keeps older releases installable; legacyPort: 0 or a
custom port still renders the flag.

863efb3d35 webdav: delete a folder with its contents (#11811)
* webdav: delete a folder with its contents

* webdav: guard the recursive delete against stale and confined paths

- propagate stat lookup errors instead of returning an error-bearing
  FileInfo: OpenFile and DELETE would otherwise take the recursive
  removeAll on a path whose type was never confirmed, wiping a
  directory on a transient filer error
- refuse wrappedFs.Rename from or to the served root, matching the
  RemoveAll guard and webdav.Dir
- normalize trailing slashes in removeAll so the delete names the
  entry itself, and refuse the root for every caller

* webdav: keep file-only deletes shallow and refuse ancestor destinations

- removeAll used by OpenFile and failed-upload cleanup now deletes
  non-recursively, so a folder swapped in after the stat check is not
  emptied by a pending file delete
- MOVE and COPY whose destination contains the source are refused
  before the handler removes the destination, which would otherwise
  take the source down with it

* webdav: also refuse a destination inside the source

a MOVE or COPY into its own subtree recurses into the destination it
just created; refuse it with the same guard instead of burning the
recursion budget for a 500

* webdav: allow a shallow copy into the source subtree

a COPY with Depth: 0 creates only the destination collection and never
reads children, so it is safe inside the source; only deep copies and
moves are refused there

* webdav: refuse a copy/move whose source is unreadable

* webdav: cover the missing-source refusal in the guard test

* webdav: 500 on a source lookup failure, 404 only when absent

Chris Lu 6a594da739 filer: free orphaned hard-link chunks and remote objects in delete sweeps (#11809)
* filer: free shared chunks when a folder delete drops the last hard link

doBatchDeleteFolderMetaAndData skipped chunk collection for every hard-linked child, relying on maybeDeleteHardLinks to retire the shared inode record. When the delete removes the last link the record is gone and nobody else will ever free those chunks. After the link callback runs, check whether the record survived; if it did not, queue the entry's chunks for deletion.

* filer: free orphaned hard-link chunks in the replayed delete sweep

The subtree sweep on a replayed directory delete skipped every hard-linked child, so a link that was the inode's last owner leaked its shared chunks. Check the inode record after the store delete; when it is gone, queue the child's chunks like any other swept entry.

* filer: mirror remote-object cleanup in the replayed delete sweep

Children a lagging peer alone still holds under a replayed directory delete were dropped with plain store deletes: their remote objects leaked and lazy remote fetches could resurrect them. The sweep now records event-stamped tombstones and deletes swept non-directory children through maybeDeleteFromRemoteIfUnchanged, which carries the same stat guard the write-back daemon's processDeleteEvent applies plus a modification-time check — a delayed replay cannot erase an object another writer replaced, even a same-size one. A failed remote delete fails the replay so the event is retried instead of orphaning the object. The directory's own tombstone comes from the event pipeline at the event timestamp and covers the subtree. Metadata-only deletes and cross-cluster events keep the origin's semantics.

* filerstore: return real errors from KvGet on MongoDB, ArangoDB, Elastic

These stores mapped every lookup failure to ErrKvNotFound, so a database error looked identical to a missing key: hard-link records could appear gone while links still owned their chunks, and path timestamp reads could treat committed state as absent. Return the underlying error and keep ErrKvNotFound for genuinely missing keys.

* filer: bind remote-object deletes to the observed object version

A guarded stat-then-delete still lets a replacement landing between the two requests go down with the deleted object. Add an optional conditional-delete operation to remote storage clients — S3 If-Match on the live ETag, GCS generation match, Azure IfMatch — and use it everywhere a delete is guarded by a stored stamp: the write-back daemon's delete, rename-source, and pending-rename paths, and the replayed-delete sweep. Backends without it keep the guarded stat-then-delete.

* filer: restamp the remote entry after a metadata-only remote update

Changing Content-Encoding rewrites the object in place on S3 and advances its LastModified, while the recorded stamp keeps the old mtime. A version-checked delete would then mistake the object for a replacement and keep it forever. Re-stat after UpdateFileMetadata so the saved stamp describes the live object.

* filer: mirror the remote-delete ownership checks in the replayed sweep

The sweep deleted swept children's remote objects on the listing's snapshot
alone. Two gaps: a remote-only entry that took the path since — one a commit
record may not cover, such as a lazy fetch materialized from the remote —
reads the object as its only copy, and an entry removed while its rename
copy was pending leaves the object at the source key orphaned. The per-child
delete now runs under the child's entry lock with the commit-time check
repeated, keeps a remote-only entry that holds the path, and releases the
pending rename's source under the same ownership and stamp conditions the
write-back daemon's releasePendingSource applies.

* remote.sync: restamp only the object the metadata update touched

The live stat after UpdateFileMetadata was saved unconditionally, so a
replacement written between the update and the stat stamped the entry with
an object it never described — and a later delete would then pass the
freshness guard on the replacement's data. The restamp now requires the live
object to still match the stored stamp on size and ETag; a different object
keeps the old stamp, which the delete guard reads as replaced and keeps.

* filer: skip unbudgeted reader-cache test on 32-bit

TestReaderCacheUnboundedWithoutBudget proves the reader cache has no
implicit memory budget by keeping 96 concurrent 4 MiB downloads in flight
(>256 MiB). On linux/386 the weed/filer test binary already runs near the
4 GiB address-space limit, so the burst reliably crashes it with
"out of memory" mid-suite.

* filer: bail out of a swept child lock instead of waiting on it

Replay already holds the event's path locks when the sweep reaches a
descendant. A local rename can hold that descendant while waiting on one
of the replayed paths, so blocking on the child lock deadlocks both. The
sweep now tries the lock and reports ErrLockContended — transient, so the
replication retry replays the event once the local write settles.

* remote: report the stamp a metadata update produced

A metadata write can rewrite the object it touches — S3 changes
Content-Encoding through an in-place copy, which can mint a new ETag —
so restamping from a fresh stat can reject the very object the update
produced, or describe a replacement that landed in between.
UpdateFileMetadata now returns the RemoteEntry of the object it wrote
(S3 from the copy result, GCS from the update attributes, Azure from a
post-update stat); nil means the object was untouched and callers keep
the stored stamp.

* remote: restamp Azure from the metadata write's own etag

eea3f232da iam: scope CreateServiceAccount's ParentUser by policy resource (#11736)
* iam: scope CreateServiceAccount's ParentUser by policy resource

AuthorizeIamAction evaluated the iam:CreateServiceAccount grant against a
hardcoded arn:aws:iam:::* resource, so the policy's Resource never had a
say; #11218 then bound the target to the caller outright. Evaluate
self-target actions against the target identity's ARN instead: a wildcard
resource keeps the deliberate any-target grant, a scoped resource confines
issuance to the named parent identity, anything else is denied.

buildResourceARN gains the ARN pass-through buildS3ResourceArn already has,
so iam: ARNs reach the policy engine intact on the attached-policies route.

Closes #11735

* ci: retrigger after unrelated weed/storage metrics flake

* iam: fold IAM-ARN matching into awsIAMMatch, drop debug test

- remove zz_debug_test.go (local debugging leftover)
- fold awsIAMMatchResource into awsIAMMatch: the arn:aws:iam:: value
  prefix selects case-sensitive matching, so no separate name is needed
- trim comments

Chris Lu 8c55425d55 s3tables: tighten legacy OIDC subject re-anchoring (#11808)
* sts: recognize issuer-scoped parent user ids

ComputeParentUser output has a fixed shape (base64url SHA-256); let
callers distinguish it from bare subject strings.

* s3tables: keep legacy owner re-anchoring off local and scoped account ids

Re-anchoring a stored bare subject under the single trusted issuer must
only apply to strings that could actually be a legacy OIDC subject. A
stored owner naming the reserved or a configured local account, or an
already issuer-scoped id, can otherwise be claimed by any caller whose
token asserts that string as sub.

* s3tables: re-anchor legacy policy principals in map and array forms

A stored bare subject can appear as {"AWS": sub} or inside a principal
list, not only as a top-level string; re-anchoring only the string form
left legacy Deny statements unable to match the caller.

* s3tables: keep built-in legacy exclusions independent of the account checker

A missing local-account predicate must not disable re-anchoring entirely:
the reserved accounts, ARN-shaped values, and scoped-id shapes are never
OIDC subjects regardless, while legacy Deny statements for plain subjects
still need to resolve so a denied caller cannot fall through to an
identity grant.

* s3tables: exercise legacy Deny against an owner grant

The previous case denied the caller regardless of whether the statement
principal matched; make the caller the owner so a missed match shows.
Cover the array Deny form alongside the AWS map.

Chris Lu 88d9926b35 s3api: recheck suspended-version condition under the lock when the filer ignores condition_alt_key (#11806)
* s3api: recheck condition under lock when routed filer ignores condition_alt_key

A filer that predates condition_alt_key silently drops the field and
evaluates a suspended-versioning condition against the empty null slot
alone, so a matching If-Match still gets a false 412. Recheck under the
object lock instead of trusting that response: the lock path resolves the
same entry the read path serves. Genuine precondition failures still
return 412 from the recheck.

* s3api: cover suspended If-Match against a filer ignoring condition_alt_key

* s3api: resend against the resolved entry instead of the lock-path recheck

Rechecking under the gateway object lock does not serialize against
routed writers, which commit under the filer's path lock; a concurrent
routed PUT could land between the recheck and the create and be
overwritten with a stale precondition. Resend the same transaction with
condition_key set to the resolved version file so the condition and the
write stay under the same filer lock. When the resolved entry is the
null slot, a delete marker, or unresolvable, the resend targets the
object path and fails closed.

Chris Lu e6a0534e3b s3api: make ambiguous routed-PUT recovery atomic and stop transaction replay (#11787)
* filer_pb: map PRECONDITION_FAILED to a sentinel error

A conditional CreateEntry that the owner's path lock refuses comes back as
FilerError_PRECONDITION_FAILED; mapping it to ErrPreconditionFailed lets the
S3 gateway tell a rejected precondition apart from a transport failure and
report 412 instead of retrying the write.

* s3api: make the ambiguous-PUT recovery create conditional under the lock

createAfterAmbiguousRoute verified state and then issued an unconditional
create, so a write landing between the lookup and the create was still
clobbered by the stale re-commit (issue #11631). The recovery create now
carries a WriteCondition — IF_NOT_EXISTS for a proven-absent entry,
IF_ENTRY_EQUAL for a directory it may need to write onto — which the owner
filer evaluates under its per-path lock, making the check and the write
atomic. A refused precondition loops back to re-read the state instead of
overwriting whatever won the race.

* s3api: do not fail over a routed transaction past a possibly-sent request

withFilerClientFailover retried the callback on the next filer on any
transport error, so an ObjectTransaction whose response was lost could be
re-applied over a write that committed in between (issue #11631). A gRPC
error cannot distinguish "never sent" from "committed", but channel
readiness can: a non-replayable callback now runs only on a connection that
just reached READY, and failover continues only over channels that never
came up — the one failure mode that provably sent nothing.

* s3api: run ambiguous-route recovery for empty PUTs too

The recovery was gated on a nonempty chunk list, so a zero-byte PUT whose
routed transaction lost its response still fell back to an unconditional
create that could overwrite a newer write and delete its chunks. Chunk-count
mismatch on an empty upload list is enough to distinguish a superseding
entry from this PUT's — there is nothing to save by skipping the check.

* s3api: keep conditional recovery creates off the replay path

The conditional create in the ambiguous-PUT fallback rode the replayable
WithFilerClient failover, so a committed create whose response was lost
could be re-sent to another filer — where a delete in between would let
IF_NOT_EXISTS pass again and resurrect an entry pointing at reclaimed
chunks. Conditional creates now run through the non-replayable failover;
an ambiguous result falls through to confirmCreateLanded, which resolves
the committed entry rather than resending.

* s3api: do not mark a filer unhealthy for an answered request

A reply that reached the callback — including an application-level failure
like a refused write precondition — proves the filer is alive. Checking
received before the health bookkeeping keeps definitive application errors
from tripping the failure circuit or flagging a live routed owner as
unreachable.

* s3api: do not claim an empty stored entry as an ambiguous PUT's own

Two chunkless entries compare equal under sameFileChunks, so an older
empty object satisfies "the route landed" even though it predates this
write — recovery would return success while leaving the request's
Content-Type and metadata unapplied. A landed PUT stores the entry
exactly as built, so require mime/size/md5/content and the extended
attributes to match before claiming it; anything else stays uncertain
and the client retries.

* s3api: prove ambiguous empty PUTs by write id and pin recovery to the owner

- Conditional recovery creates are sent to the routed owner alone instead of failing over: the condition only serializes with routed writes under the owner's per-path lock, and another filer's forwarding is only as correct as its ring view. An unreachable owner now yields an uncertain result rather than a create under a different serialization boundary.
- A proven-absent path no longer satisfies an empty, chunkless PUT: the routed commit may have landed and been deleted, and there are no chunks to verify, so IF_NOT_EXISTS could resurrect a removed object. Recovery returns uncertain for the client to retry.
- Chunkless identity moves from metadata equality to a per-write id (x-seaweedfs-write-id) stamped into Extended: an identical older object can match mime/md5/content but not the id. Entries without this write's id are not claimed, and confirmCreateLanded can now positively confirm a committed empty object instead of always reporting failure.

* filer: shrink zip spool threshold in tests to fix 32-bit OOM

On io.EOF and error paths the command returned while CreateEntry
goroutines were still running, so trailing entries could be silently

guard the shared error with a mutex.

* fs.meta.load: surface worker errors on read/unmarshal failure paths

The ReadFull and proto.Unmarshal error paths waited for in-flight

exit paths so the worker error is reported.

Extract the load loop into loadEntries so the concurrency and error
propagation can be exercised by unit tests, and add regression tests

Chris Lu 44bb697495 s3api: hydrate runtime policies on propagated IAM updates (#11784)
* s3api: hydrate runtime policies on pushed identity upserts

PutIdentity propagation (used on every IAM write when the credential
store has a master client) carries the persisted identity proto. That
proto records inline policies only as flattened legacy Actions; their
runtime __inline_policy__ names live in the policy store and were
dropped by the merge. For the interval until the next full reload, an
identity whose policy denied e.g. DeleteObject routed to legacy
CanDo, where "Write:bucket" authorizes deletes.

Hydrate the pushed identity the same way a full load does, so the
merged state always carries its runtime policy names and documents.

* s3api: hydrate runtime policies on pushed group upserts

PutGroup propagation has the same gap as identity pushes: the wire
proto does not carry the group's runtime __inline_group_policy__ names,
so members' attached-policy check lost them until the next reload.

* s3api: attach only runtime inline policy names on pushes

Listing the pushed identity's or group's own inline policies is enough
to keep it on the attached-policy route; a whole-store hydration per
pushed proto is not. Pushes now never write iam.policies, so a stale
read can no longer overwrite a newer committed policy document.

* s3api: carry inline policy documents on pushed upserts

Attaching only runtime policy names left a window where a pushed identity or group referenced a document the local cache had never loaded, denying allowed requests until the next reload. Fetch the pushed entity own inline documents and publish them with the update; reads stay scoped to the pushed entity rather than the whole store, and inline runtime names are only ever populated from this store so a read cannot install a document older than the committed one. Resync the IAM manager only when a push actually installs documents.

* s3api: order pushed inline policy reads against their installs

A pushed UpsertIdentity or PutGroup read inline policy documents from
the credential store and installed them without holding the ordering
guard that full reloads already take, so a delayed push could overwrite
a newer committed document with its stale read and restore a revoked
grant until the next update or reload.

Pushes now hold reloadMu across the store read and the install, the same
snapshot-through-commit serialization the credential-manager load uses.
MergeS3ApiConfiguration also applies config.Policies to the live
iam.policies at commit instead of swapping in its earlier snapshot, so a
policy installed while a merge prepared (a pushed inline document or a
PutPolicy update) is no longer discarded.

74ed12d6b3 s3 lifecycle: replay only the rules that fit the retention window (#11789)
* s3 lifecycle: replay only the rules that fit the retention window

runShard handed drainShardEvents the full snapshot, so rules the retention
window assigns to the walk were also matched during meta-log replay. Their
matches are not due yet, and drainShardEvents freezes the cursor at the first
event with a not-yet-due match. With a 3-day and a 30-day expiration rule on one
bucket and RetentionWindow of 8 days, every shard's cursor stopped at the first
30-day object's PUT and stayed there until that object came due. Each pass
then re-read the log from that point and re-dispatched every 3-day expiration
already handled, which surfaces as NOOP_RESOLVED dispatches, a growing
cursor_lag_max, and passes that still report status=ok.

Snapshot.ReplayView drops the replay-kind actions promoted to the walk and
keeps every other action as compiled, and the drain uses it. Promoted rules
are served by the walk as before. RulesForShard, PromotedHash and ReplayView
share one isPromoted predicate. With RetentionWindow unset no active rule is
promoted, so behaviour without a configured window is unchanged.

* s3 lifecycle: scale the replay-view test with DaysToDuration

The test took its retention window from DaysToDuration but dated its PUTs
in hours, so under the s3tests build tag (one lifecycle day = 10s) every
event fell before the seeded cursor and replay never ran. Express the
event ages in DaysToDuration too, so the test exercises replay at both
scales.

* s3 lifecycle: rehabilitate scan_only mode in the replay drain view

ReplayView shared the base CompiledAction pointers, so a replay-kind
rule locked into ModeScanOnly by a prior compile stayed invisible to
router.Route's event_driven gate even when the runtime retention window
kept it in the replay partition - and it is absent from the walk view
too, so the rule would be served by neither.

Clone non-promoted replay-kind actions the way RulesForShard does
(Mode forced to event_driven), reactivating the scan_only case whose
bootstrap rendezvous already completed, while preserving the base
active bit for genuinely pre-bootstrap actions. Disabled actions are
excluded for parity with the other views, and DESIGN.md now documents
the view.

* s3 lifecycle: keep drain activation observable, require walker with retention

ReplayView now shares pointers for event-driven actions so a mid-pass
MarkActive flip remains visible to the drain; only a scan_only-locked
action is cloned to event_driven, and reactivated only when its
bootstrap rendezvous completed (tracked via a new bootstrapComplete
field on CompiledAction).

validate() rejects RetentionWindow without Walker: promoted rules
would lose their only dispatch path while the drain cursor still
advanced past their events.

Chris Lu 443ae1cd83 s3 lifecycle: share daily bucket walk and prune listings (#11797)
* s3 lifecycle: share the daily bucket walk across shards

The daily pass invoked the walker once per shard, and every shard's
walk listed the full bucket tree while keeping only its own 1/16 of
the entries — 16 full listings per pass by default (#11791).

Run now groups the shards by the walk branch they'll take (recovery
vs steady, using the same cursor data and hash checks runShard applies)
and starts one shared walk per group, so a pass lists each bucket at
most twice. WalkerFunc and WalkBuckets take a shard set instead of a
single shard. runShard keeps its own decision and waits on its group's
walk; a shard whose freshly-loaded cursor disagrees with the plan falls
back to a per-shard walk, so mid-pass cursor rewrites can't under-cover
a shard.

* s3 lifecycle: skip the .versions/ pre-pass on non-versioned buckets

walkBucketTree listed every directory twice — once looking for
.versions/ dirs, once for regular entries. On a bucket that never had
versioning enabled the first pass can only find coincidentally-named
user folders, so the extra listing is pure cost (#11791).

FilerListFunc now takes the walk view and consults
Snapshot.BucketVersioned; non-versioned buckets skip pass 1 entirely.
A *-suffixed .versions user folder on such a bucket is recursed into
as a regular directory so real objects inside still surface; a nil
view keeps the two-pass behavior.

* s3 lifecycle: prune walk directories to active rule prefixes

The daily walk listed every directory under a bucket even when no
rule prefix could reach it. Collect the active rule prefixes of each
bucket from the walk view (new Snapshot.BucketPrefixes) and skip
recursing into directories whose keys can never match; a bucket
with no active actions is skipped entirely, saving the listing.

.uploads stays in scope regardless of prefixes because AbortMPU
rules match DestKey, and .versions expansion is pruned only
conservatively (the logical key is a string-prefix of the dir key).

* s3 lifecycle: join planned walks before Run returns

planWalks starts a shared walk goroutine per group, but a shard whose
authoritative cursor load then fails exits runShard without waiting on
it. Run returned while the walk still listed or dispatched deletes
against connections the caller closes on return. Join every planned
walk after the shard waitgroup.

* s3 lifecycle: treat object-locked buckets as versioned in the walk

Object Lock requires versioning and every writer sets both extended
attributes, but IsBucketVersioned only read ExtVersioningKey. A locked
bucket missing that attribute would have its .versions dirs walked as
ordinary folders, hiding version siblings from lifecycle. Classify
ExtObjectLockEnabledKey as versioned too.
