 - `table-catalog-strong-snapshot-v1` durable strong catalog snapshot compatibility: version 1 writes continue during mixed-version rollout until operators confirm that every serving node reads version 2, and version 1 table/view identifier collisions remain available only for cleanup. Remove version 1 writes and collision cleanup after the minimum supported RustFS release reads version 2 and every retained durable strong snapshot is collision-free and has been upgraded to version 2.
 - `table-catalog-migration-fence-v1` durable strong migration fence compatibility: version 1 "PREPARING" fences did not distinguish a known-absent global strong snapshot from an unknown baseline, so retries read them but fail closed if the global snapshot is missing. Version 2 preserves the same JSON shape and records the pre-migration global snapshot ETag in the existing target_snapshot_etag field while the fence is "PREPARING". Remove version 1 reads after every supported direct-upgrade source writes version 2 fences and operators have completed or cancelled every older in-progress backing migration.
 - `table-catalog-backing-manifest-v1-wire-labels` durable strong backing manifest labels: version 1 published "STRONG_KV_WAL" and "CUT_OVER_LINEARIZABLE_READS" before the implementation was narrowed to the ETag-CAS durable snapshot backing. Internal names and operator documentation describe the implemented semantics, while version 1 responses retain those labels for existing clients. Replace the labels only in a new manifest version with an explicit client migration contract.
+- `cross-pool-fence-v1` authenticated unsupported advertisement: predeployment servers recognize the versioned cross-pool fence capability probe but report support version 0, allowing a later all-peer probe to distinguish predeployment nodes without activating a second lock domain. Replace the unsupported advertisement only when composite lock acquisition, a cluster-wide activation fence, complete fleet proof, commit-time proof revalidation, and fail-closed revocation ship together.
 - `replacement-recovery-status-v1` replacement recovery status capability: new peers treat an unimplemented ReplacementRecoveryStatus RPC as an explicitly non-definitive rolling-upgrade response, so Admin v4 cannot claim distributed replacement completion from old peers. Remove the fallback after the minimum supported RustFS peer version implements ReplacementRecoveryStatus.
 - `table-catalog-dotted-namespace` Iceberg REST namespace path compatibility: existing RustFS clients use dotted namespace paths, while the standard multi-level contract uses the URL-encoded unit separator `%1F`. New servers accept both forms so a rolling upgrade does not invalidate existing catalog configuration. Remove the dotted fallback after the minimum supported RustFS release advertises `%1F` and all supported clients have refreshed their catalog configuration.
 - `rustfs-5509` FileInfo positional MessagePack decoding: beta.11 serialized 28 fields, while beta.12 inserted transition-version fields in the middle and serialized an incompatible 30-field array. New releases write named maps and retain readers for both shipped array layouts so direct and rolling upgrades can read either release. Remove the positional-array readers after every supported direct-upgrade release writes named maps and no retained RPC payload can contain a pre-map FileInfo array.
@@ -33,7 +34,6 @@ for later deletion.
 - `tonic-013-status-render` peer RPC failure classification: internode failures that reach a node only as text (a peer's error_info payload, a status flattened through format!) are classified by matching the rendering of an Unavailable gRPC status. Releases up to 1.0.0-alpha.38 shipped tonic 0.13, which rendered that status as "status: Unavailable, message: ..."; tonic 0.14 renders it as "code: 'The service is currently unavailable', message: ...". Both forms are matched so an older peer's relayed text still marks an unreachable peer offline. Remove the tonic 0.13 form after the minimum supported RustFS peer version ships tonic 0.14 or later.
 - `rustfs-5063` pre-beta.9 Local KMS recovery: persisted Local KMS configs from beta.8 and earlier predate the explicit insecure-development flag, and encrypted key files use the legacy SHA-256 KDF. Remove the config fallback after supported upgrades have rewritten or explicitly resaved all pre-beta.9 configs with the development-default field, and remove the legacy KDF after supported upgrades have rewritten all pre-beta.9 Local KMS key files with explicit at-rest protection.
 - `sse-local-dek-json-v1` legacy local SSE DEK decoding: releases before the JSON envelope wrote wrapped DEKs as `base64(nonce):base64(ciphertext)`, so readers retain that decoder while all new writes use the versioned JSON envelope. Remove the colon decoder after the minimum supported direct-upgrade release writes JSON envelopes and migration tooling has rewritten every retained legacy object.
-- `multipart-compression-default-off-window` staged multipart disk-compression rollout: releases before the resumable legacy decompressor fail transient reads of compressed objects under mid-payload suspension, so multipart uploads advertise the compression marker only when RUSTFS_COMPRESSION_MULTIPART_ENABLED is set in addition to RUSTFS_COMPRESSION_ENABLED, keeping rolling upgrades from creating new compressed multipart objects while pre-fix nodes may still serve reads. Flip the default to enabled (and retire the extra switch) after the minimum supported direct-upgrade release ships the resumable decompressor.

-For each tuning knob it answers three questions:
-
-1. Which stage is actually slow — `set_disk_encode`, `set_disk_rename`,
-   `metadata_fanout`, `bitrot_verify`, etc.?
-2. Is the knob the real bottleneck, or is the stage slow for another reason?
-3. Does widening/loosening the knob buy throughput without an unacceptable
-   memory (RSS) or tail-latency regression?
-
-The core discipline is **one variable per A/B cell**. Never change two knobs in
-the same cell, or the result is unexplainable.
-
-## 2. Prerequisites
-
-- Linux bench host (or an ansible-managed cluster); a laptop smoke run is too
-  noisy to decide anything.
-- `warp` on `PATH` (or pass `--warp-bin` to the driver).
-- The observability metrics runtime **enabled**. The stage histograms below are
-  not emitted when `RUSTFS_OBS_METRICS_EXPORT_ENABLED=false` or the runtime is
-  otherwise off — see
-  [`hotpath-warp-ab-runbook.md`](hotpath-warp-ab-runbook.md) for the no-log /
-  no-monitor baseline env.
-- A warm, disposable data set. Recreate the bucket per run; do not bench against
-  production data.
-
-Load driver and gate are reused, not reimplemented:
-
-- `scripts/run_object_batch_bench_enhanced.sh` — warp driver with rounds,
-  median aggregation, `baseline_compare.csv`, and Prometheus service-metric
-  capture.
-- `scripts/hotpath_warp_ab_gate.sh` — relative budget gate over the deltas.
-- `scripts/run_hotpath_warp_ab.sh` — optional orchestrator when a knob needs
-  the full baseline-vs-candidate treatment (e.g. two different defaults).
-
-## 3. Fixed test conditions (lock before you start)
-
-Record these per run; a result without them is not reproducible:
-
-```text
-nodes, disks_per_node, total_disks, cpu_per_node, mem_per_node,
-network, erasure_set_drive_count, endpoint_mode (direct|lb),
-rustfs_commit_sha, warp --version, durability mode
-```
-
-Workload matrix (the same shapes the hotpath gate uses, expanded for the
-stage-breakdown object sizes):
-
-| Workload | mode | sizes |
-| --- | --- | --- |
-| small-fixed | put / get | 4KiB, 100KiB |
-| ec-boundary | put / get | 1MiB, 4MiB |
-| large-stream | put / get | 10MiB, 16MiB, 32MiB |
-| mixed | mixed | 256KiB |
-
-Concurrency ladder: `8, 16, 32, 64` (add `96, 128` on a bigger rig). Duration
-`120s`, `--rounds >= 3`, cooldown `>= 30s`.
-
-Isolate background noise before the sweep: scanner deep-verify, heal,
-replication, lifecycle transition, periodic capacity refresh — record whether
-each is on rather than silently assuming it is off.
-
-## 4. Measurement stack
-
-The code already instruments every stage below. Drive each A/B cell with these
-histograms (names verified against `crates/io-metrics/src/lib.rs`):
-
-- PUT stages: `rustfs_s3_put_object_stage_duration_ms{stage=...}` — compute
-  P50/P95/P99 per stage. Stages: `app_bucket_validate`, `app_sse_config_lookup`,
-  `app_object_lock_config_lookup`, `app_put_opts_build`, `app_prelookup`,
-  `ingress_prepare`, `app_encryption_prepare`, `app_replication_decision`,
-  `app_store_put`, `app_post_store_bookkeeping`, `app_capacity_update`,
-  `set_disk_writer_setup`, `set_disk_encode`, `set_disk_rename`,
-  `set_disk_old_data_cleanup`.
-- GET stages: `rustfs_io_get_object_stage_duration_seconds{path=..., stage=...}` —
-  the `path` label separates the read paths: `legacy_duplex`, `codec_streaming`,
-  `direct_memory`, `body_cache`, `inline_direct`, `internal_meta`,
-  `remote_transition`, `set_disk`, `empty`. Stages: `metadata`,
-  `metadata_cache_lookup`, `metadata_fanout`, `metadata_resolve`, `object_info`,
-  `path_decision`, `quorum_reached`, `range`, `reader_setup`,
-  `stripe_read`, `stripe_read_first_shard`, `stripe_read_quorum`, `decode`,
-  `reconstruct`, `emit`, `fill`, `output_poll`, `output_lock_wait`,
-  `bitrot_verify`, `first_byte`, `full_body`, `response_handoff`,
-  `lock_acquire`.
-- EC memory pressure: `rustfs_ec_encode_inflight_bytes_current` and the
-  allocator reclaim gauge; plus node RSS and CPU.
-
-Host telemetry (collect alongside every cell):
-
-```bash
-pidstat -durh 5 > telemetry/pidstat.txt &
-mpstat 5 > telemetry/mpstat.txt &
-iostat -xz 5 > telemetry/iostat.txt &
-```
-
-## 5. Tuning knob catalog
-
-Defaults are verified against `crates/config/src/constants/object.rs` and
-`crates/ecstore/src/erasure/coding/encode.rs`.
-
-### 5.1 PUT
-
-| Knob | Default | Controls | Validating stage | Risk if widened |
-| --- | --- | --- | --- | --- |
-| `RUSTFS_ERASURE_ENCODE_MAX_INFLIGHT_BYTES` | 32MiB | EC encode producer/consumer memory budget (blocks queued between encode and shard write) | `set_disk_encode` P95 + `rustfs_ec_encode_inflight_bytes_current` | RSS growth under high concurrency |
-| `RUSTFS_OBJECT_IO_BUFFER_SIZE` | 128KiB | Streaming read-in / write-out block size | `ingress_prepare`, `set_disk_encode` | Larger buffers = fewer polls, more resident memory |
-| `RUSTFS_OBJECT_DUPLEX_BUFFER_SIZE` | 4MiB | duplex pipe capacity (shared, but PUT path uses it less than GET) | `set_disk_encode` feed smoothness | Memory per in-flight request |
-| `RUSTFS_DURABILITY_MODE` / `RUSTFS_DRIVE_SYNC_ENABLE` | mode-dependent | per-shard fsync/sync discipline on commit | `set_disk_rename` P99 | Weakening it changes the durability contract — treat as a deliberate tradeoff, not a free win |
-| `RUSTFS_RUNTIME_WORKER_THREADS` / `RUSTFS_RUNTIME_MAX_BLOCKING_THREADS` | Tokio defaults | async workers + `spawn_blocking` pool feeding per-block encode | `set_disk_encode` P95 + mpstat | Oversubscription |
-
-### 5.2 GET
-
-| Knob | Default | Controls | Validating stage | Risk if enabled |
-| --- | --- | --- | --- | --- |
-| `RUSTFS_GET_CODEC_STREAMING_ROLLOUT` | `off` | switches the read path from `legacy_duplex` to the pull-based `ErasureDecodeReader` (`codec_streaming`) | compare `path="legacy_duplex"` vs `path="codec_streaming"` for `decode`/`emit`/`output_lock_wait`/`stripe_read` | behavioral change to the read path; rollout is `off` by default for a reason |
-| `RUSTFS_GET_CODEC_STREAMING_ENGINE` | `legacy` | `legacy` vs `rustfs` decode engine under the streaming reader | `reconstruct`/`decode` per `path` | engine swap on a correctness-critical path |
-| `RUSTFS_GET_CODEC_STREAMING_MULTIPART_ENABLE` | `false` | multipart objects on the streaming reader | same, multipart cells | wider format coverage |
-| `RUSTFS_GET_CODEC_STREAMING_DATA_BLOCKS_FIRST_ENABLE` (+ `_MAX_SIZE`, `_FIRST_READER_SETUP`) | `false` / 512KiB | prefer data-shard readers before parity | `stripe_read_first_shard`/`stripe_read_quorum` | shard-selection order change |
-| `RUSTFS_OBJECT_GET_SKIP_BITROT_VERIFY` | `false` | skip per-shard HighwayHash verify | `bitrot_verify` | **do not default on** — measures the theoretical ceiling only |
-| `RUSTFS_OBJECT_DUPLEX_BUFFER_SIZE` | 4MiB | legacy GET in-process pipe capacity | `output_lock_wait`/`output_poll` | memory per in-flight GET |
-| `RUSTFS_GET_SEEK_BUFFER_ENABLE` | `false` | in-memory seek buffer for small GET | `first_byte` | experimental, startup-latched — see [`get-path-experimental-switches.md`](get-path-experimental-switches.md) |
-| `RUSTFS_GET_OUTPUT_HANDOFF_ATTRIBUTION_ENABLE` | `false` | adds `response_handoff` attribution (metrics only) | `response_handoff` | small per-request bookkeeping cost |
-
-## 6. A/B matrix
-
-Run each row as an independent cell. Baseline is the shipped default; candidate
-is one knob moved. Everything else (topology, sizes, concurrency, rounds,
-durability) stays fixed.
-
-### 6.1 PUT
-
-| # | Knob | Baseline | Candidates | Signal metric | Judgement |
-| --- | --- | --- | --- | --- | --- |
-| P1 | encode in-flight | 32MiB | 48MiB, 64MiB, 96MiB | `set_disk_encode` P95 + throughput + RSS | throughput up AND `set_disk_encode` down AND RSS tolerable → budget was the binding constraint |
-| P2 | object I/O buffer | 128KiB | 256KiB, 512KiB, 1MiB | `ingress_prepare` + `set_disk_encode` | encode smooths with bounded RSS → upstream feed was too small |
-| P3 | duplex buffer | 4MiB | 8MiB, 16MiB | `set_disk_encode` feed variance | lower priority than P1/P2 |
-| P4 | blocking threads | default | 512, 768, 1024 | `set_disk_encode` P95 + mpstat | per-block `spawn_blocking` is scheduler-bound if P95 falls |
-| P5 | durability | current mode | weaker/stronger mode | `set_disk_rename` P99 | only as a **deliberate durability tradeoff**, never a silent default change |
-| P6 | set drive count | current | other valid widths | all PUT stages | highest cost — only after P1–P5, and only on a rebuildable topology |
-
-### 6.2 GET
-
-| # | Knob | Baseline | Candidates | Signal metric | Judgement |
-| --- | --- | --- | --- | --- | --- |
-| G1 | codec streaming rollout | `off` | `on` (pct ramp 10/50/100) | `path="legacy_duplex"` vs `path="codec_streaming"` for `decode`/`emit`/`output_lock_wait`/`stripe_read` + throughput | streaming beats duplex on `decode`+`output_lock_wait` and byte-for-byte output matches → candidate for default |
-| G2 | codec streaming engine | `legacy` | `rustfs` | `reconstruct`/`decode` per `path` | engine swap is neutral-or-better on CPU with identical bytes |
-| G3 | multipart streaming | `false` | `true` | multipart GET cells | only after G1 is stable on single-part |
-| G4 | data-blocks-first | `false` | `true` | `stripe_read_first_shard`/`stripe_read_quorum` | fewer shard reads without a correctness regression |
-| G5 | duplex buffer | 4MiB | 8MiB, 16MiB | `output_lock_wait`/`output_poll` (legacy path) | only if still on `legacy_duplex` |
-| G6 | skip bitrot verify | `false` | `true` | `bitrot_verify` | **ceiling measurement only**; do not carry into production |
-
-## 7. Execution sequence
-
-1. Freeze the conditions in §3 and record the provenance block.
-2. Run the baseline cell (all defaults) and capture stage histograms + host
-   telemetry.
-3. Pick the **one** most-likely knob from the analysis. For large-object PUT
-   that is almost always `set_disk_encode` → P1; for GET it is G1 (the
-   `legacy_duplex` → `codec_streaming` switch).
-4. Sweep that knob's candidate column one value at a time, same workload.
-5. Read the decision table in §8; if the stage did not move, the knob is not
-   the bottleneck — stop widening it and pick the next stage.
-
-Driver invocation for one PUT cell:
-
-```bash
-scripts/run_object_batch_bench_enhanced.sh \
-  --tool warp --endpoint http://127.0.0.1:9000 \
-  --access-key "$RUSTFS_ACCESS_KEY" --secret-key "$RUSTFS_SECRET_KEY" \
-  --bucket rustfs-put-tuning --warp-mode put \
-  --sizes 16MiB,32MiB --concurrency 32 --duration 120s --rounds 3 \
-  --out-dir target/bench/put-tuning-p1-64mib
-```
-
-## 8. Interpretation / decision table
-
-| Stage high | Most likely cause | Next action |
-| --- | --- | --- |
-| `set_disk_encode` | per-block EC encode scheduling + in-flight budget | P1 → P4 → P2, in that order |
-| `set_disk_rename` | commit tail (rename fan-out / RPC / fsync) | P5 (durability) and cluster tail analysis, not encode |
-| `set_disk_writer_setup` | per-disk `BitrotWriter` + temp-file create | disk/filesystem metadata; per-disk fan-out cost |
-| `set_disk_old_data_cleanup` | overwrite / versioned-object directory delete | confirm overwrite-vs-new-write; defer cleanup further |
-| `metadata_fanout` / `metadata_resolve` | cross-disk `xl.meta` read + quorum | metadata cache hit rate; small-object fixed cost |
-| `bitrot_verify` | HighwayHash verify on the read path | G6 ceiling only; do not default on |
-| `output_lock_wait` / `output_poll` | legacy duplex backpressure | G1 (move off duplex) or G5 |
-| `stripe_read*` | shard concurrency / selection | G4 shard-selection, disk/network tail |
-
-## 9. Guardrails
-
-- **Never weaken correctness for throughput**: read/write quorum, bitrot verify,
-  `xl.meta` validation, and durability (`RUSTFS_DURABILITY_MODE`) are integrity
-  contracts, not knobs. P5 and G6 are ceiling measurements and must be labelled
-  as such; do not carry their values into production without an explicit
-  durability/correctness decision.
-- **One variable per cell.** A cell that changes two knobs is thrown away.
-- **Memory is part of the result.** A throughput win with unbounded RSS growth
-  is a regression; record RSS and the EC in-flight gauge for every PUT cell.
-- **Startup-latched knobs** (`RUSTFS_GET_SEEK_BUFFER_ENABLE`,
-  `RUSTFS_GET_OUTPUT_HANDOFF_ATTRIBUTION_ENABLE`, and the codec-streaming
-  switches) require a process restart to change — see
-  [`get-path-experimental-switches.md`](get-path-experimental-switches.md).
-- **Archive the raw data.** Keep the `baseline_compare.csv`, `median_summary.csv`,
-  stage histograms, and host telemetry per cell; the conclusion must trace back
-  to them. Do not commit benchmark result snapshots to the repo — record them in
-  the issue tracker.
