fix(ecstore): preserve remote preparation corruption

Encode actual reader data into private local shards and recover matching write-quorum receipts. Preserve original metadata and namespace owners across retries and cancellation, without granting publication authority.

Validate with 13 focused tests and two rejected digest/quorum mutations. Document the preparation and recovery boundary.

 Read only after the final non-preview tag has passed Phase 6. Tag creation or a green binary build alone is insufficient: the release assets, source archive, container images, Helm package, and applicable latest channels must be available. Preview tags never enter this phase.
 
-## Security Advisories
-
-Reconcile advisories after every completed final release, including Console-only releases. Read-only preparation may start earlier; do not claim an unpublished artifact is an available fix.
-
-1. Fetch every page of the repository's live Security Advisories, including triage, draft, published, and closed states. A permission error or partial response blocks reconciliation; it does not mean there are no advisories. Keep unpublished advisory details in private task artifacts, never in a public PR, release note, or issue.
-2. For each potentially relevant advisory, map its fix to the exact published tag and verify the regression evidence. Main-branch reachability, a merged private fix, or a green build alone does not prove the shipped version is fixed. Check cherry-picked equivalents and reverted fixes explicitly. For embedded Console or dependency fixes, verify the shipped component version.
-3. Determine the first available fixed release and affected version ranges from evidence. Preserve an earlier correct patched version; do not relabel all fixes as the current release. An unchanged server baseline such as a Console-only release requires checking the earlier server release as well. Leave unresolved reports and fixes absent from the tag pending; do not close them merely because a release shipped.
-4. Prepare any necessary corrections to package identity, affected ranges, patched versions, fix/release links, and advisory text. Preserve unrelated fields, credit, CVE identifiers, and disclosure coordination. Apply updates only within existing user authorization; read back the result to verify it. Publishing a draft, requesting a CVE, or closing a report is a separate action: require explicit authorization for the concrete advisories and respect any embargo. Release-tag approval alone does not authorize those actions. Prepare the exact proposed changes before asking for missing authorization.
-5. Record each relevant advisory's URL, current state, fix evidence, first fixed version, action taken or proposed, and remaining blocker in private task artifacts. Report advisory follow-up separately from artifact publication. A successful release with unresolved advisory work is not complete follow-up; retain that work for the release monitor or a concrete user decision.

For this config-only change, type-check and lint the changed file, build the site, and inspect the generated homepage for the version, visible link text, and destination. Confirm `/download` actually offers the announced version before using that link.
 4. Commit, push, and create or update the website PR when included in the authorized release scope. Include the published RustFS Release URL and checks run. Keep merge and production-deployment authority separate; reuse permission already given, but this reference grants none by itself.
 5. After an authorized merge/deployment, verify the live `https://rustfs.com/` banner and its destination. If only the PR is ready, report that state and URL; do not report the banner as deployed. A website failure does not invalidate or move the published release tag: retry this phase after resolving the failure.
-
-## Reconcile main and remove the completed release branch
-
-1. Compare the exact published tag with current main. Audit every release-side commit since their merge base, including inherited backports. An ahead count is a history difference, not proof of missing changes. Use ancestry and patch equivalence, then inspect current code and regression evidence for squashed, adapted, superseded, or reverted changes. Record each commit as present, superseded, release-only, or missing; a positive `git cherry` result alone does not prove a missing fix.
-2. Bring missing shared changes to main through a reviewed PR and the required checks before closing the follow-up. Preserve main's later changes; decide version bumps and pinned Console configuration separately. If a history merge is needed, use a merge commit and verify the release commit is an ancestor of main; squash does not establish that ancestry. Do not merge main into the published release branch or move its tags. Report unresolved changes instead of claiming reconciliation is complete.
-3. After publication and authorized follow-ups are complete, delete the remote `release/<target>` branch. Immediately before deletion, verify its HEAD still equals the published tag's commit and no open PR targets or originates from it. Preserve a branch with newer work or open PRs and report the blocker. Use a deletion with an expected-old-SHA check to avoid removing a concurrently advanced branch.
-4. Verify the remote branch is absent and the final and preview tags still resolve to their recorded commits. Remove a local release branch only if it is task-owned, unchecked out, and has no unpreserved work. Record cleanup separately from artifact publication; an explicitly authorized deletion before reconciliation does not make unresolved main changes complete.

 - `GHSA-6r96-hmgc-726c`: request headers collided with lowercase server-derived condition keys such as `userid`, `groups`, `versionid`, and JWT/LDAP claims. Lesson: never let caller-controlled headers append to or replace server-derived policy context; reserve trusted condition keys and keep intentional request-header keys separate.
 - `GHSA-v9cp-qfw9-9pfp`: quantified negated string conditions applied negation after aggregation, transposing `ForAllValues` and `ForAnyValue` semantics. Lesson: push negation into the per-value predicate for quantified operators and test partially overlapping multi-value sets.
 - `GHSA-5w8r-p896-6vq2`: OPA policy mode skipped `ExistingObjectTag/*` loading, so tagged objects looked untagged to external policies. Lesson: external authorization plugins need the same object-tag and request context as built-in policy evaluation before they decide.
-- `GHSA-9wgh-5r68-49p7`: substituted policy-variable values could recreate `${...}` and loop inside a single resolution pass, never reaching the outer iteration limit. Lesson: bound substitutions within each pass and test cycles formed across otherwise literal resolver values; confirm whether attacker-controlled claims can reach those values before assigning remote impact.
 
 ### S3 object actions, copy, multipart, and upload policy validation
 
 - `GHSA-g8w9-qw9q-fghr` and `GHSA-xm99-m3gq-83g8`: a valid presigned `PutObject` accepted extra `x-amz-*` headers omitted from `SignedHeaders`; `x-amz-copy-source` could turn that upload capability into a cross-bucket read performed as the signer. Lesson: a presigned URL is a bounded capability; inspect all received security-sensitive headers and reject unsigned ones before selecting the S3 operation or reaching storage.
 - `GHSA-3ppv-fx5m-m749`: explicit `versionId` reads and copy sources authorized `s3:GetObject` instead of `s3:GetObjectVersion`. Lesson: version-specific object access must select version-specific actions for direct reads, `CopyObject`, and `UploadPartCopy`, with tests proving the backend is not reached on denial.
-- `GHSA-cg33-pxfp-qcj3` and `GHSA-65wq-gjw8-xr9w`: `HeadObject` and object-tagging paths authorized current-object actions while operating on an explicit historical `versionId`. Lesson: select the corresponding version action for metadata and tag reads and writes too; audit every operation that accepts a version ID.
 - `GHSA-gjph-xcgw-4p7w`: `PutObject` and browser POST accepted a caller-supplied `versionId` and replaced an unlocked historical version with only `s3:PutObject`. Lesson: only replication-authorized writes may choose an existing version ID; ordinary uploads must not rewrite version history.
 - `GHSA-x298-9x87-fvjq`: anonymous `ListObjectVersions` fell back to `ListBucket` and returned before public-access-block gates. Lesson: compatibility fallbacks must converge on the same post-authorization checks as direct grants, especially `RestrictPublicBuckets` and anonymous data-plane denies.
 - `GHSA-mx42-j6wv-px98`: `UploadPartCopy` missed source authorization and allowed cross-bucket object exfiltration. Lesson: multipart copy must enforce the same source and destination contract as `CopyObject`.

 - `GHSA-j548-9grx-fh4f`: Object Lock enforcement treated unreadable, fabricated, or unparsable bucket metadata as absent configuration and allowed retained objects to be deleted or expired. Lesson: retention must fail closed unless Object Lock absence is authoritative, and every delete, lifecycle, scanner, force-delete, and default-retention path needs the same state distinction.
 - `GHSA-28w4-rp2p-636w` and `GHSA-c7hx-vr97-45rg`: an authorized `DeleteBucket` with `x-rustfs-force-delete: true` removed active COMPLIANCE-retained versions even though ordinary version deletion was denied. Lesson: bucket force-delete must enforce retention across every version, including against root/owner callers.
-- `GHSA-q23w-fp7p-472v`: `PutObjectRetention` policy conditions read `x-amz-object-lock-*` headers while the handler applied mode and date from the XML body. Lesson: authorize the parsed retention that will be stored, or reject mismatched header/body values; compare retention dates as instants so offsets cannot change the applied bound.

-# Workflow runners: what is billed and where a job belongs
-
-**Use this when:** adding a job, changing a `runs-on`, moving a lane between runner pools, or deciding whether a new check is worth its runner cost.
-**Source of truth:** `runs-on` in each workflow file for current placement; `.github/actionlint.yaml` for the declared self-hosted labels; the organisation's Settings → Billing → Usage page for what is actually charged; `docs/testing/ci-gates.md` for which checks block a merge (that does not change when a runner changes).
-
-## Billing facts
-
-This repository is public. For a public repository, GitHub's standard hosted runners (`ubuntu-latest`, `windows-latest`, `macos-latest`) cost nothing and have no minute cap, whatever plan the organisation is on. GitHub bills only two things: larger hosted runners, which have custom labels and are not used here, and standard runners in private repositories.
-
-Every other label in this repository is capacity RustFS pays for. ARC pods and lab machines accrue cost while the machine exists. A Ubicloud label is metered for the minutes a job holds its VM:
-
-| Label | Paid by | What it is | Use it for |
-|---|---|---|---|
-| `ubuntu-latest` | nobody | GitHub-hosted, Ubuntu 24.04, 4 vCPU, 16 GB RAM, about 14 GB of free disk. Ships a C toolchain, `docker`, `gh`, `curl`, `wget`, `jq`, Python. Can `mount` tmpfs and loop devices; io_uring works | the default for every job |
-| `windows-latest`, `macos-latest` | nobody | GitHub-hosted standard runners | Windows and macOS targets |
-| `sm-standard-2` | RustFS | ARC pod, Ubuntu 24.04, minimal image: no `gh`, no C toolchain; Docker only on the `dind-` label | only a job that a hosted runner cannot run (see the placement rule) |
-| `sm-standard-4` | RustFS | ARC pod, Ubuntu 24.04, 14 CPUs and 28 GB (the label is not the core count), large disk | workspace-scale Cargo builds |
-| `ubicloud-standard-16-arm` | RustFS | Ubicloud VM, alias of `ubicloud-standard-16-arm-ubuntu-2404`: Ubuntu 24.04 arm64, 16 vCPU, 48 GB, 300 GB disk. Reached through the `build.yml` matrix, so `actionlint.yaml` does not list it | native aarch64 release builds (`linux-aarch64-musl`, `linux-aarch64-gnu`) |
-| `dind-sm-standard-2` | RustFS | ARC pod with Docker-in-Docker | image builds that need `buildx` and a registry push |
-| `smoke-testing`, `pf-testing` | RustFS | long-lived lab machines | the packaged functional chain and performance suites |
-
-The self-hosted pods and the hosted image are both Ubuntu 24.04, so a binary built on one runs on the other; `ci.yml` builds the debug binary on `sm-standard-4` and runs it on both pools.
-
-## Placement rule
-
-A job runs on `ubuntu-latest` unless it has one of these reasons, and the reason goes in a comment next to its `runs-on`:
-
-1. **Disk.** It restores or produces the workspace `target/`: `cargo build` or `cargo test` with `--all-targets`, `cargo nextest run --all`, or any reader of the `ci-dev` / `ci-feat-*` caches. The workspace test build leaves about 64 GB in `target/`; a hosted runner has about 14 GB.
-2. **Critical-path CPU.** It is a build that several downstream lanes wait on and would blow its timeout at 4 vCPU (`build-rustfs-debug-binary` gates the e2e and s3-tests lanes).
-3. **Hardware.** Native aarch64, Docker-in-Docker, or the lab machines.
-4. **Cache ownership.** It reads a `rust-cache` key that a self-hosted job writes (see the cache rule below).
-
-Jobs that do only the following have no reason to be self-hosted: shell or Python scripts, `cargo fmt`, `cargo deny`, typos, actionlint, API calls (`gh`, dependency review, issue and stale bots, CLA checks), downloading an artifact and running a prebuilt binary, or a `cargo build -p rustfs` with its own cache key. `e2e-distributed.yml` and `e2e-upgrade.yml` build the server and the `e2e_test` harness on `ubuntu-latest` inside their budgets, so "it compiles something" alone is not a reason.
-
-A hosted runner is also the only choice for a few things the pods cannot do: `mount -o loop` and `mount -t tmpfs` fail inside the ARC pods, and a container runtime cannot guarantee that `io_uring_setup` is allowed. `uring-integration` and `e2e-distributed` are on `ubuntu-latest` for that reason, not for cost.
-
-## Cache rule
-
-`Swatinem/rust-cache` builds its key from the OS, architecture, toolchain and lockfile. It does not include the runner label or image, so a cache written on an `sm-standard-4` pod and one written on `ubuntu-latest` would overwrite each other under the same `shared-key`.
-
-- Every `shared-key` has exactly one writer. `cache-warm.yml` owns `ci-dev`, `ci-feat-rio`, `ci-feat-proto` and `ci-uring`; every other `./.github/actions/setup` call states `cache-save-if` explicitly, and `scripts/security/check_cache_save_if.sh` fails the build when one does not.
-- All readers of a key run on the same image as its writer. Keys that live on hosted runners say so in their name (`ci-uring` is warmed on `ubuntu-latest`; `ci-e2e-distributed-hosted`, `e2e-upgrade-server-hosted`, `e2e-upgrade-tests-hosted`).
-- Moving a job between pools therefore means renaming its key. The new key is empty until a run from `main` (a scheduled run, or a manual dispatch of that workflow from `main`) saves it; until then that lane does a cold build. The `build.yml` aarch64 release legs append `-ubicloud-arm` for this reason. `cache-warm.yml` does not write those keys.
-- `CARGO_BUILD_JOBS` and every other `CARGO*`, `CC*`, `CFLAGS*`, `CXX*`, `CMAKE*` and `RUST*` variable is hashed into the key. `ci.yml` sets `CARGO_BUILD_JOBS` at step level for that reason; promoting it to job level rotates the key for every lane that shares it.
-
-## Where self-hosted minutes leak
-
-These are the patterns that have cost real money here without validating anything more:
-
-- An `if: always()` summary or alert job on a self-hosted label inside a `workflow_run`-triggered workflow. The upstream workflow completes many times a day, the real jobs skip, and the summary still starts a pod each time. Gate it on the upstream job having run, and keep it on `ubuntu-latest`.
-- Per-push workflows on `main`. A merge triggers the full `ci.yml` matrix, `cache-warm.yml` and the `build.yml` development build; with tens of merges a day that is as much self-hosted time as all pull requests together. Anything that does not verify the merged tree itself belongs on a schedule or behind a `paths` filter.
-- `apt-get install` of tools the hosted image already ships. It is only needed on the minimal pod images.
-- A throttled `CARGO_BUILD_JOBS` on a 14-CPU pod. The limit exists for link-storm reasons documented in `ci.yml`; measure before raising it, and measure before lowering it further.
-- Tiny jobs on ARC pods. Each one pays roughly a minute of pod start-up before its first step; a compile-free job that takes ten seconds costs more to schedule than to run.
-
-## Measuring a run
-
-To see which pool each job of a run used and for how long:
-
-```bash
-gh api "repos/rustfs/rustfs/actions/runs/<run_id>/jobs?per_page=100" \
-  --jq '.jobs[] | "\(.conclusion)\t\(.labels | join(","))\t\(.started_at)\t\(.completed_at)\t\(.name)"'
-```
-
-Only rows whose label starts with `sm-`, `dind-`, `ubicloud-`, `smoke-` or `pf-` cost anything. At the October 2026 review, a full pull-request run of `ci.yml` spent about 150 self-hosted minutes, a third of it in jobs that never compiled; treat that as the scale of what a placement mistake costs, not as a current figure.
-
-## Checklist for a new or moved job
-
-- `runs-on` is a literal label. A new self-hosted label is declared in `.github/actionlint.yaml` in the same change (`.github/AGENTS.md`).
-- The job declares `timeout-minutes` (`scripts/security/check_job_timeouts.sh`).
-- `actionlint` reports nothing.
-- A self-hosted `runs-on` carries a comment naming its reason from the placement rule.
-- Every `./.github/actions/setup` call states `cache-save-if`, and a key read from one pool is not written from the other.
-- Moving a job does not change its check name, so the `main` ruleset and `docs/testing/ci-gates.md` stay as they are; renaming it does, and then that document's change checklist applies.

 - 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)).
-- A `set-remote-target?update=true&creds=true` request on a site-replication peer's bucket target is now rejected with `400 InvalidRequest`, naming the target and why it counts as peer-owned. It used to return success while keeping the stored endpoint, credentials, and TLS settings, so an endpoint edit from the Console's bucket replication form appeared to apply but did not. Change a peer's address with a site-replication edit instead; see "Changing a site's address" in `docs/operations/site-replication-operations.md`. The `sync`, `bandwidth`, `proxy`, and `path` update groups are unchanged.
-- Site-replication edits that omit the site name, such as `mc admin replicate update --deployment-id <ID> --endpoint <URL>`, now keep the stored name on the editing site and on every receiver instead of renaming the site after the new endpoint host. No persisted format changes.
 - 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.
 
 ### Fixed
-- **`mc admin info` and `mc admin replicate resync` work again**: since the cluster snapshot view (#3803), `GET /v3/info` and `GET /v3/storageinfo` returned the madmin `InfoMessage` / `StorageInfo` nested under an `info` key next to `admin_discovery` (and, for `/info`, `bitrotSelftest`). madmin decodes those bodies directly, so `mc admin info` printed empty values and `mc admin replicate resync start/status` rejected every alias with "alias provided is not part of cluster replication" because the local `deploymentID` read as empty. Requests on the MinIO-compatible `/minio/admin/v3` prefix now receive the bare madmin body again; `/rustfs/admin/v3`, which rc and the console use, keeps the envelope unchanged.
-- **Replication status writebacks no longer invalidate scanner cycles**: every replication status writeback (`persist_replication_state_if_current` in `Update` mode, including the heals the scanner queues during its own walk) marked the bucket dirty on the namespace path, advanced the dirty-usage generation and woke the scanner, so a site-replication resync or any steadily replicated bucket ended every cycle `superseded`, the authoritative usage baseline was never certified, and the console reported usage freshness as stale for as long as replication ran (#8375). Those writebacks are now status class: they do not touch the dirty-usage generation, the activity snapshot, the dirty-usage wake or the durable dirty journal, and only the process-local producer coverage is recorded. They need no rescan queue, because a deployment with an active replication rule already walks every bucket on every cycle and that walk refreshes `replication_stats`. Tier-expiration cleanup, which removes data, stays on the namespace path. No persisted format, protocol, admin API or configuration changes. Design: `docs/architecture/scanner-per-bucket-convergence.md`.
-- **A bucket written during a scanner walk no longer supersedes the whole cycle**: the post-walk cluster activity proof required the entire activity snapshot and the dirty-usage generation to be unchanged, so a single-node deployment with one bucket written every few seconds never reached a `Complete` cycle, `usage_snapshot_converged` never became true and the authoritative usage baseline was never certified (#8494). Dirty usage is now certified per bucket: a structurally complete walk that the guardrail did not veto is `Complete`, buckets whose dirty generation still matches the start snapshot are cleared, and buckets written during the walk stay dirty and are published as the pending set, so `usage_snapshot_converged` means "no bucket pending" and the next cycle is scoped to the pending buckets. Such a cycle writes the authoritative usage object; the observed object is now selected by an explicit observational mark that vetoed cycles carry. The guardrail itself vetoes only on the fields that change which namespace the walk described (peer set, process instance, protocol version, topology, maintenance generation, data movement, movement generation, publication blocked) and reports the field and host in the scanner log and in the new `usage_freshness` fields `guardrail_veto_total`, `last_guardrail_veto_unix_secs` and `last_guardrail_veto_reason`. In a distributed deployment a remote peer whose dirty usage moved during the walk still supersedes the cycle until scoped acknowledgements can name its buckets. `.usage.v2.json` gains the additive, default-when-absent fields `usage_snapshot_pending_buckets`, `usage_snapshot_pending_bucket_count` and `usage_snapshot_observational`; older readers ignore them and treat the snapshot as an authoritative but unconverged publication. Quota is unchanged: an uncertified bucket keeps its last usage value as the floor and live writes do not advance it. No protocol or configuration changes. Design: `docs/architecture/scanner-per-bucket-convergence.md`.
 - **SSE-C TLS requirement now covers copy-source keys**: with `RUSTFS_SSE_C_REQUIRE_TLS=true`, a `CopyObject` or `UploadPartCopy` that carried only the `x-amz-copy-source-server-side-encryption-customer-*` headers (an SSE-C source copied to a destination that is not SSE-C) was accepted on a plaintext transport and was not counted in `rustfs_ssec_plaintext_requests_total`, although those headers carry the source object's customer key. They now count as SSE-C headers: such requests are counted, and refused with `400 InvalidRequest` when the switch is on. Requests over TLS are unaffected.
 - **SSE-KMS encryption context could replace the location entry**: data keys are wrapped under an encryption-context entry, keyed by the bucket name, that ties them to the object's location. A client `x-amz-server-side-encryption-context` entry under the same key replaced it, and because the client context is stored with the object, the replacement also applied on every read. SSE-KMS writes now refuse such a context with `400 InvalidArgument`; other keys, including the names of other buckets, are unaffected. Objects stored with such an entry by an earlier release remain readable. See `docs/operations/kms-backend-security.md`.
 - **Two admin handlers reported a missing policy or user as `500 InternalError`**: `GET /rustfs/admin/v3/info-canned-policy` and `DELETE /rustfs/admin/v3/remove-user` wrapped every IAM error as an internal fault instead of classifying it, so a lookup for something that does not exist answered `500 InternalError` where the rest of the admin API answers `404 NoSuchResource` — `GET /rustfs/admin/v3/user-info` already did, and `iam_error_to_s3_error` already mapped `NoSuchPolicy`, `NoSuchUser`, `NoSuchServiceAccount` and `NoSuchTempAccount` to `NoSuchResource`. A client could not tell "does not exist" from a real server failure, and a controller that checks existence before creating (a Kubernetes operator reconciling policies or users) could never create the object: the missing-policy lookup failed with a `500` and it retried forever. Both handlers now map their IAM errors through the shared `iam_error_to_s3_error` helper, so a missing policy or user is `404 NoSuchResource` and the `error` is preserved as the S3 error's source; the three IAM calls in the removal path (temporary-user lookup, service-account lookup, delete) are all reclassified, and every other IAM error stays `500 InternalError`. Fixes #8117.

 ### Changed
-- **Scanner bucket walkers are no longer tied to the disk count**: a new scanner key `walkers_per_disk` (`RUSTFS_SCANNER_WALKERS_PER_DISK`, `1` through `16`, default `1`) spawns that many bucket walkers per local disk of an erasure set, so a single-disk deployment can walk several buckets at once instead of one bucket, one object at a time. The walkers of one disk share its scanner admission, so a peer still sees one scan session per physical disk, and remote disks keep one walker. The walker count is what `max_concurrent_disk_scans` caps and the disk count stays the floor; the `disk_concurrency_budget` log line now reports `walkers_per_disk`, `walkers`, and the `reason` for the effective limit. The default keeps today's I/O profile because a local disk cannot yet report whether it is rotational; the design intends a higher default on flash once it can (`docs/architecture/scanner-per-bucket-convergence.md`). As groundwork for pacing, the raw-enumeration page writer inserts into its building page in place and commits pages without copying them, and a regression test pins the cost of recording 20,000 entries in one prefix so the quadratic bookkeeping removed by [#8114](https://github.com/rustfs/rustfs/pull/8114) (rustfs#8113) cannot return. No persisted format, protocol or admin API changes beyond the additional config key, which older releases preserve and ignore.
 - **Encryption and KMS work merged since `1.0.0-rc.5`** (entries were missing from this section):
   - **Persisted KMS configuration secrets** are sealed field-by-field with `RUSTFS_KMS_CONFIG_SECRET`. **When the variable is unset the secrets are persisted in cleartext and the server only warns** (`persisted KMS configuration carries cleartext secrets`); it never refuses the write. Set it, identically, on every node, and re-save the configuration to seal an existing one.
   - **New v2 ciphertext frame format** with per-frame index binding and final-frame authentication. Its write switch `RUSTFS_ENCRYPTION_FRAME_V2` is **off by default**: v2 frames are unreadable by nodes without v2 read support, and encrypted ciphertext travels verbatim through transition, decommission and SSE-C replication passthrough, so turn it on only after every node — and every RustFS warm/replication target that receives raw ciphertext — runs a release with v2 read support. Reading v2 objects needs no switch.
