 ## [Unreleased]

-### Replication
-
- Object Lock replication PUTs now carry a required integrity header, fixing target rejection introduced by the plain-payload default ([#7097](https://github.com/rustfs/rustfs/pull/7097)). This changes the default outbound request for locked objects but adds no persisted format.
- Multipart source objects stay on the multipart transport even when their checksum record is a whole-object checksum, so objects above the single-PUT limit remain replicable ([#7047](https://github.com/rustfs/rustfs/pull/7047)).
- Targets that mint their own version IDs now use a per-target version ledger for tag, retention, legal-hold, and permanent-delete mutations; ambiguous pre-ledger matches fail with backoff instead of guessing ([#7368](https://github.com/rustfs/rustfs/pull/7368)). This adds dual-prefixed internal metadata keys that older readers ignore.
- Single-part source checksums are forwarded as `x-amz-checksum-*` headers instead of user metadata, so the replica preserves checksum responses ([#7313](https://github.com/rustfs/rustfs/pull/7313)). This changes the default outbound headers for checksummed objects.
- Site-replication outage recovery now uses a bounded 30-second retry drain plus the 600-second full reconciliation pass, persists destructive liabilities before local deletion, and fences replay settlement and peer edits ([#7148](https://github.com/rustfs/rustfs/pull/7148)). Persisted additions are optional and ignored by older readers.
- IAM snapshot/deletion replay, target-assigned delete-marker purges, timestamp ordering, and best-effort peer broadcast now close the control-plane gaps found by the R6 review ([#7195](https://github.com/rustfs/rustfs/pull/7195)).
- Upgrade and rollback: upgrade every node in one site consecutively and verify reconciliation before moving to the next site; do not intentionally run a site mixed-version. Target-version ledger keys are harmless on rollback, although old code cannot use their routing. Before rolling back past [#7307](https://github.com/rustfs/rustfs/pull/7307), drain or repair every pending version purge: older code can free a retained version's data directory before its remote purge is acknowledged. See `docs/operations/site-replication-operations.md`.
-
 ### Security
 - **Presigned URLs honour only signed headers** (GHSA-g8w9-qw9q-fghr): a SigV4 presigned request that carries an `x-amz-*` request header not listed in `X-Amz-SignedHeaders` is now rejected with `403 AccessDenied` ("There were headers present in the request which were not signed"), matching AWS S3. Previously the holder of a presigned `PutObject` URL could add unsigned `x-amz-tagging`, `x-amz-storage-class`, `x-amz-website-redirect-location`, ACL, metadata, Object Lock or SSE headers and have them applied. Presigners that intend a property must set it before signing so the SDK lists the header in `SignedHeaders`; `x-amz-cf-id` (CloudFront) remains tolerated unsigned. Header-signed SigV4 and SigV2 requests are unchanged.

-## Replication Support Boundary
-
-Site replication and bucket replication are not the same compatibility claim.
-Site replication requires RustFS-compatible peer admin APIs and coordinates
-IAM, topology, buckets, and metadata. A generic S3-compatible service can only
-be a bucket-replication data target.
-
-For a generic S3 target, RustFS supports object PUT/HEAD/DELETE, multipart
-uploads, tags, version deletes, and Object Lock mutations when the target
-implements the corresponding S3 APIs and has versioning enabled. Targets that
-mint their own version IDs are supported through a per-target version ledger;
-pre-ledger replicas are adopted only when exact key and ETag identify one
-unambiguous target version. `NoSuchVersion` for an already absent addressed
-replica is treated as converged.
-
-The following are capability boundaries, not universal S3 claims:
-
- `GET /BUCKET?replication-check` must pass the phases required by the intended
-  workload. `VersionFidelity` may report a minting target as mismatched even
-  though ledger-addressed delete and Object Lock phases succeed.
- A target that rejects standard multipart constraints, required Object Lock
-  integrity headers, or the configured checksum framing is unsupported until
-  its transport settings are made compatible.
- SSE-S3 and SSE-KMS are decrypted at the source and re-encrypted by the
-  destination's KMS. SSE-C uses ciphertext passthrough and requires target
-  evidence. Unsupported or ambiguous encryption metadata fails closed.
- ACL authorization is intentionally unsupported, and generic targets never
-  receive RustFS IAM/site-control-plane state.
- RustFS does not guess between multiple target versions with the same key and
-  ETag. The mutation remains failed and retryable until repair establishes an
-  unambiguous mapping.

-# Site Replication Operations
-
-**Use this when:** operating a site-replication deployment, diagnosing a peer
-outage or incomplete topology change, pairing sites that already contain data,
-or planning an upgrade.
-
-**Source of truth:** `rustfs/src/admin/handlers/site_replication.rs`,
-`rustfs/src/site_replication/`, and the bucket-replication worker under
-`crates/ecstore/src/bucket/replication/`.
-
-Site replication combines two different convergence paths:
-
- the control plane replicates buckets, bucket metadata, IAM, and topology;
- ordinary bucket replication moves object versions and delete operations.
-
-An `enabled: true` response only says that a site has more than one configured
-peer. It does not prove that every peer is reachable or caught up. Always read
-`pendingOperation`, `retryStats`, `PeerErrors`, and `Metrics` as well.
-
-## Routine checks
-
-Run these commands from an admin workstation with one alias per site:
-
-```console
-mc admin replicate info site-a
-mc admin replicate status site-a
-```
-
-Check more than one site. A partition can leave each side with a different but
-locally valid view.
-
-`replicate info` is the compact control-plane view:
-
-| Field | Interpretation |
-|---|---|
-| `enabled` | More than one site is configured; this is not a health verdict. |
-| `sites` | The locally persisted topology. Compare deployment IDs and endpoints on every site. |
-| `retryStats.pending` | Collapsed peer deliveries waiting to be retried. |
-| `retryStats.failed` | Deliveries that crossed the escalation threshold and require attention. |
-| `retryStats.lastError` | A redacted summary of the most recent delivery failure. |
-| `pendingOperation` | A durable multi-step topology operation described below. Absence is the healthy steady state. |
-
-`replicate status` adds detailed convergence state:
-
-| Field | Interpretation |
-|---|---|
-| `Sites` / `PeerStates` | Configured peers and derived reachability/configuration state. |
-| `PeerErrors` | A peer could not be queried. Its detailed counters may be absent; do not read zeros as success. |
-| `BucketStats` | Per-bucket presence and versioning, replication, lifecycle, Object Lock, and metadata mismatches. |
-| `PolicyStats`, `UserStats`, `GroupStats` | IAM inventory mismatches. |
-| `RetryStats` | Durable control-plane retry backlog and escalation count. |
-| `Metrics.replMetrics` | Per-destination online state, downtime, replicated counts/bytes, and `failed` totals/windows. |
-| `Metrics.queued` / `Metrics.inProgress` | Object work waiting or active on the responding node. |
-| `Metrics.errors` | Node-level object-replication failures. When only queue statistics are available, RustFS synthesizes a node entry and preserves this counter rather than reporting zero. |
-| `Metrics.retries` | Redeliveries. Always zero today: a failed object is not retried by an event, it waits for the scanner pass described below. Read `errors` instead. |
-
-Healthy means: the same topology is visible on all sites, no pending operation,
-no peer error, no failed retry escalation, required bucket/IAM state is in sync,
-and queue/error counters are stable or falling. Counters are cumulative; alert on
-their rate and on a backlog that does not drain, not merely on a non-zero total.
-
-## Pending operations and recovery
-
-`pendingOperation` contains `operation`, an opaque `id`, `pendingPeers`, and
-`ackedPeers`. Do not edit the site-replication state object by hand. The marker
-is the crash-recovery journal and removing it can make a partially applied
-operation look complete.
-
-The heavyweight reconciler runs once at startup and every 600 seconds. The
-lightweight retry drain runs every 30 seconds. A restart is therefore a valid
-way to cause an immediate heavyweight pass after the underlying fault has been
-fixed, but it is not a substitute for fixing connectivity, credentials, TLS,
-or the remote endpoint.
-
-### `remove`
-
-The original topology and each peer acknowledgement are persisted before the
-operation finalizes. While peers remain in `pendingPeers`, restore access to
-them and wait for reconciliation. If a peer is permanently gone, a new remove
-request may remove all currently active unacknowledged peers; RustFS permits
-that request and then finalizes against the remaining topology. Removing the
-local site or all sites is also an explicit completion path.
-
-Do not re-add a site merely to hide this marker. First compare the topology on
-all reachable peers. If the same operation ID makes no progress for more than
-one heavyweight interval, collect `PeerErrors`, `RetryStats`, and the
-site-replication logs before retrying the remove.
-
-### `rotate-svc-acct`
-
-Service-account rotation keeps the candidate secrets and peer acknowledgements
-until every current remote peer accepts the rotation. Restore the failing peer
-and allow the reconciler to resume it. Do not manually delete either candidate
-credential during this window: doing so can remove the only credential that a
-not-yet-acknowledged peer accepts.
-
-After the marker clears, verify `replicate status` from every site, then retire
-any separately retained old credential material according to local policy.
-
-### `endpoint-refresh`
-
-An endpoint, CA, or TLS-verification edit first refreshes the replication
-target on every active peer and records acknowledgements. On startup and every
-heavyweight pass, RustFS probes peer capability, uses the endpoint-refresh API
-when supported (or the legacy peer-edit fallback), refreshes local bucket
-targets, and commits the edit only after every still-active peer acknowledges.
-
-If this marker is stuck:
-
-1. Confirm that the proposed endpoint and CA are correct and reachable from
-   every site, not only from the admin workstation.
-2. Restore the site-replication service account and TLS trust path.
-3. Wait for one 600-second pass or restart one healthy node to trigger the
-   startup pass.
-4. Re-run the identical edit only if the operation remains visible; a different
-   endpoint edit is rejected while the existing refresh is pending. The journal
-   pins the edit's payload, so a re-run without `--replicate-ilm-expiry` keeps
-   the value the first attempt recorded, and a re-run asking for a different
-   value is rejected. Finish or remove the pending refresh before changing it.
-
-A peer removed from the topology no longer blocks completion. A remove request
-is accepted when it removes every active unacknowledged peer.
-
-While this marker is present, control-plane retry replay to the other peers
-keeps running, but bucket wiring reconciliation waits: it rewrites the same
-targets the refresh is changing. Expect bucket-level drift on this site to
-persist until the refresh settles.
-
-## Outage recovery and convergence time
-
-Control-plane retry begins on the 30-second drain, while heavyweight snapshots,
-pending topology operations, and bucket wiring are revisited on the 600-second
-pass. Object MRF entries are persisted every 10 seconds by default and target
-health is probed every 5 seconds. These are scheduling bounds, not delivery
-SLAs: network timeouts and the amount of queued work add to them.
-
-Objects that must be rediscovered by the scanner have this conservative upper
-bound before discovery:
-
-```text
-RUSTFS_DATA_USAGE_UPDATE_DIR_CYCLES
-    × max(RUSTFS_SCANNER_CYCLE, actual duration of one scanner cycle)
-```
-
-The defaults re-descend a compacted directory every 16 cycles. A practical
-production starting point for a tighter recovery objective is
-`RUSTFS_DATA_USAGE_UPDATE_DIR_CYCLES=4`; `1` forces re-descent every cycle.
-Measure the additional disk and metadata load before lowering it further or
-tuning the scanner cadence. For an immediate operator-driven recovery, start a
-site resync with `mc admin replicate resync start` and monitor its status.
-Transfer time after discovery remains proportional to backlog size, bandwidth,
-worker capacity, and target latency. Use queue depth and the rate of
-`Metrics.errors` rather than the formula alone to decide whether convergence is
-progressing.
-
-## Pairing sites that already contain data
-
-When more than one requested site is non-empty, preflight considers each bucket
-name held by more than one site:
-
- versioning must be `Enabled` on every site holding the shared bucket;
- Object Lock enablement must be identical on every holder.
-
-A bucket present on only one site is safe: post-add backfill creates it on the
-other peers. A shared unversioned bucket is rejected because merging can
-overwrite the only copy of an object. An Object Lock mismatch is rejected
-because lock enablement cannot be changed after bucket creation and convergence
-could otherwise strip a WORM guarantee.
-
-If preflight rejects the pair, keep the authoritative copy, delete the
-conflicting bucket (or its contents) from all other sites, run `replicate add`
-again, and then start `replicate resync` from the surviving site. Back up and
-validate the authoritative data before deleting anything.
-
-## IAM convergence and repair boundary
-
-Ordinary IAM changes are delivered to each peer. A successful bulk IAM import
-also schedules one collapsed full-IAM snapshot per remote peer. A failed IAM
-deletion is replayed before that snapshot so the snapshot cannot re-create a
-principal or grant that was already revoked.
-
-The safety state has two bounds:
-
- deletion high-water marks are retained for 30 days;
- deletion replay bodies are capped at 256 distinct entities per peer.
-
-Repeated deletion of the same entity replaces its saved body. When the per-peer
-cap is exceeded or the body cannot be serialized, the retry entry remains
-escalated rather than pretending the deletion is replayable. An item from an
-older sender without a source timestamp cannot install the 30-day high-water
-mark, so verify it explicitly after a prolonged split. A successful drain
-clears replay bodies; removing the peer prunes its bodies. For an escalated IAM
-retry, use the site-replication repair workflow for the affected peer and IAM
-family, then verify users, service accounts, groups, policies, and mappings on
-both sides. Repair is the operator's explicit accountability transfer and
-clears the saved deletion bodies only after the IAM repair succeeds.
-
-A group's status converges in one direction. An explicit disable is applied
-everywhere, including through a snapshot, but a membership change never
-carries an enable - it would otherwise re-enable a group frozen on the
-receiving site. If a group ended up disabled on one site only, re-enable it
-there explicitly with `mc admin group enable`; a snapshot or repair will not
-do it.
-
-Treat IAM divergence as a security incident: a user deleted on one site can
-remain usable on an unreachable peer until replay or repair completes. A peer
-whose IAM entry is escalated does not receive scheduled snapshots either -
-including the one a bulk import schedules - until the repair settles it.
-
-## Encrypted objects
-
-| Source form | Replication behavior | Fail-closed condition |
-|---|---|---|
-| SSE-S3 | The source decrypts the object; the request sends only `AES256` intent; the destination encrypts with its own KMS. Source envelope material never leaves the site. | The destination cannot satisfy the encryption request, or the source metadata is incomplete/unsupported. The replica is `FAILED`; plaintext is not silently stored. |
-| SSE-KMS | The source decrypts the object; the request sends `aws:kms` intent without the source-local key ID; the destination selects its own configured KMS key. | Either side cannot decrypt/encrypt, or the metadata mixes incompatible encryption evidence. |
-| SSE-C | Stored ciphertext and the required SSE-C replication transport metadata pass through. RustFS verifies target evidence before accepting the replica. | The target does not echo the customer-algorithm evidence, required material/layout is absent, or the metadata is ambiguous. |
-
-Unknown MinIO/RustFS encryption markers are never forwarded as ordinary user
-metadata. They fail replication so an operator must migrate or repair the
-object with a supported format.
-
-## Rolling upgrades and rollback
-
-Keep every node in one site on the same version whenever possible. Upgrade all
-nodes of one site consecutively, verify its startup reconciliation and status,
-then move to the next site. Do not intentionally leave a site mixed-version:
-admin requests can land on different nodes, and an older node may not resume a
-new pending-operation shape or expose its health fields.
-
-Current state additions are optional and defaulted, so older readers ignore
-them. The target-version ledger is stored as dual-prefixed internal object
-metadata and is also ignored by older readers; rollback does not corrupt the
-object format, but older code loses the assigned-version routing improvement.
-
-Before rolling back across the fix that retains the data directory of a version
-awaiting purge replication (rustfs/rustfs#7307), ensure no version purge is
-pending. Older code can free that retained version's data directory before the
-remote purge is acknowledged, leaving unreadable metadata and blocking bucket
-deletion. Drain or repair replication and take a metadata/data backup first.
-
-## Runtime knobs
-
-These values are read when the owning background task starts. Restart the
-server after changing them. The millisecond intervals have a 10 ms floor;
-invalid values fall back to the default with a warning.
-
-| Variable | Default | Effect |
-|---|---:|---|
-| `RUSTFS_REPL_HEALTH_CHECK_INTERVAL_MS` | `5000` | Remote-target health probe interval. Lowering it increases outbound probes. |
-| `RUSTFS_REPL_MRF_FLUSH_INTERVAL_MS` | `10000` | Maximum periodic interval between MRF persistence flushes; 1,000 new entries also trigger a flush. |
-| `RUSTFS_REPL_RESYNC_POLL_MAX_MS` | `60000` | Upper bound for randomized resync retry-poll sleep. |
-| `RUSTFS_REPL_RESYNC_MAX_JOBS` | `2` | Concurrent resync jobs; values are bounded to `1..=32`. |
-
-Transport-specific controls and target behavior are documented in
-[Replication outbound transport](replication-outbound-transport.md). Validate a
-new destination with [Replication target check](replication-check.md), and read
-[Replication object size limits](replication-object-size-limits.md) before
-moving large objects.

+`pending_gates` names the unimplemented release requirements and
+`pending_lanes` names the structured release lanes that still need real
+evidence. Schema 1 is deliberately marked `release_schema_capable: false`
+because it models only the single-version, unversioned-object restart/crash
+cases. Schema 2 can describe the wider release matrix, but approval still
+requires every registered case to verify and every required gate to leave
+`pending` only after a future checker can bind it to real feature-specific
+evidence. The current checker hard-rejects missing structured requirements and
+pending gates mapped to an implemented lane, so clearing pending text cannot
+become approval. A focused run, synthetic harness, compile-only result,
+skipped/retried test, ordinary CI success, or unregistered mixed-version,
+rollback, EC8+4 or performance claim therefore cannot become a release approval.
+For high-risk rollback gates, `evidence_fields` records the specific proof
+fields that a future real-evidence checker must bind before a pending gate can
+move out of the blocked set. G03 keeps scoped ACK tied to durable root
+publication, ACK request identity, participating peer capability snapshots, and
+mixed-peer fallback oracles; G09 keeps mixed-version reader, writer, and rollback
+payload evidence explicit. These fields are part of the release contract, not
+evidence by themselves.
+
+When the real release lanes have produced their dedicated artifacts, validate
+the complete hard-gate bundle with:
+
+```bash
+scripts/python_bin.sh scripts/check_test_wiring.py \
+  --check-scanner-heal-release-bundle /path/to/release-evidence.json
+```
+
+The bundle checker is intentionally stricter than the case checker. It requires
+schema 2 registry metadata, `evidence: measured`, the current checkout revision,
+all G01-G14/P1-P4/R-E/R-D/R-L gates, per-gate `status: pass`, lane identity,
+relative artifact paths, matching SHA256 hashes, and non-empty summaries. It
+also binds each evidence field to its own run provenance: `source_revision`,
+`run_id`, `measurement_window_id`, timezone-qualified `started_at` and
+`finished_at`, command arguments, and artifact format. The field
+`source_revision` must match the bundle revision, and measured performance
+duration cannot exceed the recorded run window.
+
+The hard evidence shape remains claim-specific: mixed-version gates must name at
+least two participating versions, crash/durable replay gates must include
+crash-boundary evidence, G14 must record EC8+4 with at least three nodes and four
+drives per node plus multi-set and multi-pool evidence, performance gates need
+measured durations, P3's pressure run needs at least two hours, and P1 needs a
+symbolized profile summary with resolved samples. Every G14 field and every
+performance gate's fields must also share one `measurement_window_id`, so EC8+4,
+multi-set/multi-pool, ABBA, throughput, and profiling artifacts cannot be
+stitched together from unrelated runs. P1 `profile_evidence` must bind every
+required profile artifact kind (`allocation-profile`, `flamegraph`,
+`rss-samples`, and `save-frequency`) with a relative path, artifact format,
+non-empty file, matching SHA256, and the same measurement window when a
+per-artifact window is declared. Missing, synthetic, stale, tampered, undersized,
+or topology-mismatched evidence returns a compact blocked or invalid JSON result
+and a nonzero exit.
+
+This command validates the evidence package; it does not create evidence. A
+handwritten JSON file, a synthetic harness pass, a single focused case, or a
+local unit fixture still cannot satisfy the distributed, mixed-version,
+crash-restart, durable MRF replay, EC8+4, ABBA, or profiling gates.

houseme	a159f312f0	fix(heal): reuse same admission request id (#7451 ) Keep a retried heal start with the same request id from bypassing admission deduplication when the transport replay cache is unavailable but the manager still owns the task.

houseme	2f6f095298	test(scanner): cover flat-bucket quantum fairness (#7449 ) Add a production-entry scanner cohort regression that combines a wide flat bucket with a small bucket under a fixed object budget. The test keeps partial budgeted rounds unpublished, verifies small buckets are only marked after real execution, and confirms a later unbudgeted round can publish the complete aggregate.

houseme	60fa33773a	fix(common): retain unmatched MRF repair proofs (#7447 ) Add a recorded verified-repair consumer that discharges only exact retained anchors for the requested bucket while leaving unmatched proofs in the event ring. This gives the future durable successor writer a fail-closed primitive before any tombstone or GC path is enabled. Co-authored-by: zhi22915 <qiuzgang@gmail.com>	2026-09-08 09:16:47 +08:00
