-Require the exact final SemVer target before version edits or publication. If unspecified, inspect current releases/tags and ask with concrete candidates; do not guess the channel or bump.

+Require the exact final SemVer target before version edits or publication. If unspecified, inspect releases/tags and ask with concrete candidates; do not guess the channel or bump. Reuse the user's confirmed target and authorized delivery scope. Independent read-only preflight may continue.

 ## Invariants

- Cargo stores `<target>`, never `-preview.N`. Before publication, installation defaults retain the previous available deliverable. Final and preview binaries embed their own tag names, so version/asset names differ despite identical source.
- Use annotated tags without `v`. Preview names are exactly `<target>-preview.<digits>`; choose the next unused iteration after fetching tags. Preview Releases are prereleases, never Latest; publish only versioned assets/exact Docker tags, never latest assets, R2, Helm, moving Docker channels, or installation/banner updates.
- `release/<target>` owns the candidate. Retain its history, backport only reviewed fixes, and never merge main wholesale or force-push it. Pin `PREVIEW_HASH` to its exact commit with complete passing CI. Preview and final tags both point there; never tag a later main/branch HEAD or insert another bump.
- Phase failures block dependents. Keep preview Releases until final publication and notes generation finish; CI removes Releases while retaining tags. Never move an existing preview or final tag.
+- Cargo and every candidate executable contain the final product version. `<target>-preview.<run_number>` is an immutable candidate identifier, not a public tag or displayed binary version.
+- Freeze the exact source, reviewed workflow recipe, toolchain, Console, CLI, dependency lock, previous stable version and validation plan. Newer unrelated main or Console releases do not change those inputs.
+- Retain `release/<target>` history when a release branch is used; backport only reviewed fixes. Pin `CANDIDATE_SHA` to its exact CI-validated commit. Never force-push a release branch or move a public tag.
+- Build Linux first. Complete field acceptance before macOS/Windows and packaging. Full certification and final acceptance are required before publication; a partial Linux PASS grants no release authority.
+- Promote the accepted bytes. Final publication never recompiles binaries or rebuilds packages/images. Infrastructure retries reuse successful artifacts; changed source or inputs require a new candidate and affected acceptance.
+- Phase failures block dependents. No latest/default-channel update before versioned delivery. Use the [pipeline runbook](../../../docs/operations/release-pipeline.md) for executable entry points, locks and recovery.

-After Phases 3–5 pass, recheck that the release branch still equals `PREVIEW_HASH` and that the current Console asset tag/digest match the preview's recorded build inputs.

Explicitly ask whether to publish this exact manifest and end the turn without dispatching publication.

-Only a new affirmative user reply to that exact report authorizes Phase 6. The original release request, earlier confirmation, silence, or automated follow-up does not count. Confirmation binds the target, preview tag, hash, and accepted build inputs; a changed value or repeated/failed acceptance cycle invalidates it. Revalidate and obtain fresh confirmation before continuing.

-## Recovery
+## Recovery and reporting

- Before the final tag exists, land fixes on main, backport to the candidate, verify target versions, and restart branch CI/acceptance. Use a new preview iteration once a preview was tagged; main may advance independently.
- If only an external build input changed, record it, create a new preview iteration even when the source SHA is unchanged, and repeat the affected build and artifact acceptance before fresh confirmation. Reuse source checks whose inputs remain valid.
- Once the final tag exists, retry publication jobs for that exact tag. A source fix requires a newly confirmed target, not retagging or a newer preview. Phase 7 retries recheck artifact availability and superseding releases.
- If abandoned after the bump merged, report the unpublished version on main and record whether to revert or let the next release overwrite it. Deleting unpublished candidate branches or preview tags requires an explicit decision. Completed release branches follow Phase 7 cleanup; keep release tags.
-
-Report completed phase results and incomplete work with evidence: Console previous/latest tags, release need, hash and run/Release URLs; target, branch CI/SHA, previews and hash, confirmation state; preview/final assets, latest-channel state, Console/rc results and cleanup; advisory reconciliation results and pending disclosure decisions; both milestone states, installation PR checks/merge state, and website text/link/PR/deployment state. Keep artifact publication separate from follow-up delivery; do not call an open PR a live update. Report deviations and their authorization.
+Resume failed infrastructure jobs without rebuilding successful units. Fix product defects on main, backport when needed, and start a new candidate. After a final tag exists, retry the same bytes or use a new patch version; never move the tag. Do not conflate implemented, CI-passed, field-accepted, approved, published and post-release-complete states. Report incomplete work and deviations with evidence; a tag or green build alone is not a completed release.

-## Phase 6 — Publish the final tag on the validated commit
+Dispatch `release-publish.yml` on main with the successful completion run ID and approved `release-manifest.json` SHA-256. Do not create the tag manually. The workflow revalidates source, bytes and trusted certification, then creates the annotated final tag at `CANDIDATE_SHA`. A recipe change fails closed and requires a new candidate; unrelated main changes do not require a rebuild.

-No second source version bump. Before creating the final tag, recheck the remote `release/<target>` HEAD equals `PREVIEW_HASH` and the current Console release tag/asset digest still match the accepted preview inputs. If either changed after confirmation, the approval no longer applies; validate the changed inputs with a new preview and obtain fresh confirmation. The final tag goes on the exact commit the preview validated:
+Require both versioned publication and channel publication jobs to succeed. Verify the final tag's commit and manifest identity; all six platform ZIPs and compatibility aliases; DEB/RPM, checksums, SBOM, provenance and evidence bundle; both multi-architecture image variants in Docker Hub, GHCR and Quay; and the accepted Helm chart in the chart repository. Download a host-compatible final artifact and confirm its digest is exactly the accepted candidate digest and its version/source output agrees.

-```bash
-git fetch origin --tags
-git rev-parse "<preview-tag>^{commit}"          # must equal PREVIEW_HASH — abort if not
-git tag -a "<target>" -m "Release <target>" "$PREVIEW_HASH"
-git push origin "<target>"
-```
+For stable releases verify GitHub Latest, R2 download aliases and `latest.json` unless a newer stable release already owns those channels. Prereleases must remain GitHub prereleases and leave stable pointers unchanged. Verify generated release notes compare against the frozen previous stable release, excluding internal previews.

- CI rebuilds from the same source with a different tag name, so the binary self-reports `<target>`. Other inputs can change: `build.yml` reads Console `releases/latest` during each build. Compare the actual Console tag, URL, and verified digest in every final build job with the accepted preview record, and inspect available build provenance for other relevant changes. A pre-tag check cannot prevent a later input change. On a mismatch or missing evidence, repeat affected acceptance against the final artifacts and report the limitation; failed acceptance leaves release validation incomplete even if publication already succeeded. Never move the final tag to conceal a failure.
- Verify the final tag's complete publication path: all matrix and release jobs green; `gh release view "<target>"` shows the full versioned and `-latest` asset set plus checksums, SBOM, and provenance; Docker and Helm workflows succeed; `latest.json` points to `<target>`. A stable target must have `isPrerelease=false` and `isLatest=true`. An alpha/beta/rc target must have `isPrerelease=true`; GitHub does not permit prereleases to be Latest, but the project `latest.json` still advances to the final non-preview target.
- Verify the final Release body contains `## What's Changed` and a Full Changelog link. When `PREVIOUS_DELIVERABLE` exists, the link MUST be `https://github.com/rustfs/rustfs/compare/<PREVIOUS_DELIVERABLE>...<target>` and the baseline MUST equal the preview Release baseline; for example, both `1.0.0-beta.12-preview.1` and `1.0.0-beta.12` compare from `1.0.0-beta.11`.
- Verify the preview cleanup: `cleanup-preview-releases` must succeed and `gh release view "<preview-tag>"` must then report `release not found` for every preview iteration of this target. Each surviving preview tag must still resolve to its own recorded commit; the accepted preview resolves to `PREVIEW_HASH`. If the job failed, delete the leftover Releases manually with `gh release delete "<preview-tag>" --yes` and report it.
- Verify a host-compatible final artifact's checksum and `./rustfs --version`; it must report `<target>` and the expected source SHA. This identity check does not replace affected acceptance when build inputs changed.
+On infrastructure failure retry the same workflow/seal; matching destinations are reused. Never clobber an asset, force a tag, rebuild the image or silently accept a changed digest. A source fix after the final tag requires a new patch version. Cross-registry writes are not atomic: report the unfinished destination rather than claiming publication complete.

-Never pass `--cleanup-tag` when removing preview Releases. Remove them manually only if `cleanup-preview-releases` failed, after final publication and notes generation. Record deleted Releases and surviving tags.
+New candidates create no preview Releases to clean up. For a legacy preview release, preserve its tag and remove its Release only after final delivery and notes are verified. Do not pass `--cleanup-tag`. Complete the [post-release follow-up](post-release-updates.md) separately.

- The canonical suffix is exactly `-preview.<digits>`. `build.yml` recognizes it before alpha/beta/rc classification and routes it to the preview-only path; any other tag containing `-preview` fails closed instead of being treated as a release.
- A preview Release MUST be published with `isPrerelease=true` and `isLatest=false`. Any `*-latest` preview asset or preview-triggered `latest.json`, R2, Helm, or moving Docker channel tag is a pipeline failure. Docker images may use the exact preview version tag, including its existing variant suffixes.
- Preview Releases are cleaned up by the `cleanup-preview-releases` job after `publish-release` succeeds for the deliverable tag. It deletes every Release whose tag is exactly `<target>-preview.<digits>` and never passes `--cleanup-tag`, so the tags survive.
+Verify the frozen Console identity equals the one accepted in Phase 0. Every matrix job consumes that same digest and exact toolchain. The binary must report the final product version and source commit; its candidate ID is separate. No public tag, Release, registry tag, R2 release path, Helm repository or latest pointer should change during this stage.

-## Phase 3 — CI and preview Release verification
-
- Find and watch the tag build: `gh run list --workflow build.yml --branch "<preview-tag>" --limit 1` then `gh run watch <run-id>`. Every build matrix target must succeed (linux x86_64/aarch64 × musl/gnu, macos-aarch64, windows-x86_64).
- Confirm the preview tag resolves to the Phase 2 CI-validated `PREVIEW_HASH`. If the release branch advances during acceptance, repeat Phases 2–5 with a new preview tag.
- Confirm the Release publication jobs (`create-release`, `upload-release-assets`, and `publish-release`) succeed while `update-latest-version` is skipped.
- Record the inputs actually consumed by each build job: source SHA and the embedded Console release tag, asset URL, and verified SHA256 from the download logs. The workflow reads Console `releases/latest` separately for each build; confirm the matrix used the Console asset accepted in Phase 0. A missing identity or differing asset blocks acceptance until resolved. Retain available toolchain and build provenance with the artifact checksums; the same source SHA alone does not establish equivalent builds.
- Verify `gh release view "<preview-tag>" --json isPrerelease,assets,url`: `isPrerelease` must be `true`, and the Release must contain all 6 versioned platform zips, checksums, SBOM, and provenance with no `-latest` assets. Confirm `gh api repos/{owner}/{repo}/releases/latest --jq .tag_name` does not return `<preview-tag>`.
- Record `PREVIOUS_DELIVERABLE`, selected from published Releases by `publishedAt` after excluding the current tag and every `-preview.N` tag. Verify `gh release view "<preview-tag>" --json body --jq .body` contains `## What's Changed` and, when `PREVIOUS_DELIVERABLE` exists, `**Full Changelog**: https://github.com/rustfs/rustfs/compare/<PREVIOUS_DELIVERABLE>...<preview-tag>`. For a repository with no previous deliverable, verify a Full Changelog link exists and record the GitHub baseline fallback.
- Confirm Helm is skipped. If preview Docker images are published, confirm they use only exact preview tags (and variant suffixes), with no `latest`, `alpha`, `beta`, or `rc` channel updates. Preview validation covers the built RustFS binaries, embedded console, and rc compatibility; it does not authorize advancing any installation default.

-## Release notes
-
- When a previous deliverable exists, GitHub Release notes for the preview and final tags MUST use it as their shared comparison baseline: the most recently published non-preview Release before the target. Internal `-preview.N` Releases are explicitly excluded from that selection, even when they point at the same commit as the final tag — cleanup runs after the notes are generated, so the preview Release is still present and would otherwise be picked as the baseline. If no previous deliverable exists, omit `previous_tag_name` and record that GitHub's default baseline fallback was used.
- Generated Release notes carry a workflow-management marker so retries can repair them. Before manually curating a generated body, remove that marker; unmarked non-placeholder notes are preserved by later workflow runs.
+A green Linux run is ready for field acceptance, not publication. The partial certification must have `publish_allowed: false`.

-Pushing the tag triggers `.github/workflows/build.yml` ("Build and Release"); `docker.yml` chains off it via `workflow_run`.

-The preview run builds versioned artifacts and publishes them in a GitHub prerelease. Docker may publish exact preview image tags. Latest-channel, R2, and Helm publication must be skipped; installation references and the website announcement stay unchanged.
-
-On a restart after a backport, re-run release-branch CI before setting the new `PREVIEW_HASH`. Use the next unused preview iteration when the validated commit differs from an existing preview tag; never move an existing tag.
+- Set `CANDIDATE_SHA` to the CI-validated release-branch commit. Record the branch, exact commit and CI run URL. The new candidate protocol starts from a commit whose release recipe matches the reviewed main dispatcher; backport the recipe before freezing an older release branch if needed.
+- Dispatch the Linux candidate as described in [candidate verification](preview-release.md). Do not create a preview or final tag here. The final executable already contains `<target>`; publication later promotes those same bytes.
+- After a source or build-input change, run the affected source checks and create a new candidate. Reuse the frozen candidate after an infrastructure failure. Do not restart acceptance for unrelated main advances.

 |---|---|
 | `prepare` | Only `Cargo.toml` and `Cargo.lock`: workspace package, internal dependency, and workspace member versions become `<target>`. External dependencies stay unchanged. |
 | `post-release` | Only `README.md`, `README_ZH.md`, `flake.nix`, `helm/rustfs/Chart.yaml`, and `rustfs.spec`. Cargo may already target the next release; leave it untouched. |

-Before installation edits, verify the exact non-preview Release, downloadable assets/source archive, pullable `rustfs/rustfs:<target>` image manifest, and published Helm chart. Block on missing artifacts. Do not downgrade defaults if a newer deliverable superseded the target. Preview preparation retains the previous published installation references; follow-up commits never replace either validated tag.
+Before installation edits, verify the exact non-preview Release, downloadable assets/source archive, pullable `rustfs/rustfs:<target>` image manifest, and published Helm chart. Block on missing artifacts. Do not downgrade defaults if a newer deliverable superseded the target. Candidate preparation retains the previous published installation references; follow-up commits never replace validated tags or sealed artifacts.

 Packaging policy:

- Docker image tags have no `v` prefix. Derive chart/app versions with `scripts/helm_chart_version.sh <target>` (`beta.N -> 0.N.0`; other versions unchanged). Helm CI derives versions from the final tag, so no early chart bump is required.
+- Docker image tags have no `v` prefix. Derive chart/app versions with `scripts/helm_chart_version.sh <target>`; both equal the final product SemVer, including prerelease suffixes. Helm CI uses the frozen candidate version before sealing, so no early installation chart bump is required. Previously published chart versions remain unchanged.
 - RPM `Version` is numeric; `Release` is the prerelease suffix or `1` for stable. Expanded `Source0` and the unpack directory must resolve to the exact target including its suffix. Add the changelog entry using current git identity, date, and target; never copy an example identity/date.
 - Changing these mappings requires explicit confirmation.

 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:

 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.

-The functional chain's `prepare` and `complete-chain` jobs, the performance runner availability check, and runner hygiene use `ubuntu-latest`: they inspect APIs or artifacts, not the lab hosts. The actual functional and performance suites remain on their lab runners. Functional-chain health collection uses `ubuntu-latest` so a lab outage cannot also stop its independent monitor. Docker image packaging also uses `ubuntu-latest` for both musl and glibc variants; it downloads release binaries rather than compiling the workspace, and still sets up QEMU and Buildx explicitly.

 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.

 - 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.

+## Release stages
+
+The [candidate release pipeline](../../docs/operations/release-pipeline.md) builds Linux first and defers paid desktop capacity until acceptance. Daily development builds also select Linux; use manual platform selection for desktop development artifacts. All six platforms remain required before publication. The pipeline records and promotes the exact tested bytes. Builder workflows have no public-release credentials. Keep periodic development builds, PR verification and field-test chains separate when their contracts differ; do not re-enable disabled workflows as part of a source-file migration.

+Larger runners remain billed for public repositories; see [GitHub runner billing](https://docs.github.com/en/actions/concepts/runners/larger-runners#billing). Actual spending comes from organization billing, not runner labels or an estimated build duration.

 Running, queued, failed, canceled, and completed decommission states exclude the source from new ordinary publication, including new multipart uploads. Previously created multipart uploads retain their drain path while the source remains non-terminal; terminal source states reject further multipart publication. Failed and canceled entries become writable for new ordinary publication only after an allowed clear operation removes that state. This check does not change repair admission or the separate fence for operations that only release capacity.

+Bucket creation and deletion remove stale bucket usage through namespace maintenance, independently of the scanner publication pause. Failed or canceled decommission state alone does not reject that cleanup. The update checks the logical snapshot revision while holding the fixed and physical object locks, then conditionally publishes to a writable pool; a suspended source remains available for decommission to reconcile against the newer target. Cleanup preserves the scanner epoch and cycle, and retains the bucket namespace and movement guards until its physical writes finish even if the request is canceled. Namespace lease loss still fences the write. Scanner publication continues to require its existing movement admission.
+
 For mixed batch deletes, only the pools selected to receive new delete markers are publication targets. Exact-version deletions on other pools remain protected by the same pool metadata read fence, without treating the retiring source or an unrelated reserved target as a destination for those markers.

Readers resolve bound members by that UUID before checking the existing commit and rollback proofs. A new pool at a removed member's old index cannot impersonate that member. New publications bind every member, while positional records remain readable and gain identities only after their existing authority is verified. Replica schema 1 is retained; 1.0.4 readers ignore the additive identity field and still use positional membership.
+
+Finish upgrading all scanner-capable nodes before changing pool membership. An older writer can replace a bound record with a positional one. If a legacy record was already stranded by pool reindexing, the missing identity cannot be guessed safely: restore the known topology in which its proof was readable, then let the updated writer bind the membership before changing it again. Do not delete or reset the backlog ledger to bypass this check. Partial writes, canceled callers, missing members, and conflicting authority remain subject to the native CAS and recovery rules above.

+# Candidate acceptance and release publication
+
+RustFS builds the final product version before publication. A candidate is identified by its Actions run and `<version>-preview.<run_number>`; this identifier is not a Git tag or the executable's displayed version. Failed candidates consume no public version. A public tag is created only after the complete artifact manifest is approved.
+
+## Entry points
+
+| Workflow | Input | Result | Public writes |
+|---|---|---|---|
+| `release-candidate.yml` | Exact final version and full source SHA | Four Linux archives, native checks, upgrade results, Linux manifest | None |
+| `release-complete.yml` | Successful candidate run, accepted Linux manifest SHA-256, backlog acceptance report | Desktop archives, DEB/RPM, OCI images, Helm chart, full certification and sealed manifest | None |
+| `release-publish.yml` | Successful completion run and approved final manifest SHA-256 | Annotated tag, GitHub Release, R2 files, registry images, stable pointers and Helm index | Explicit publication |
+
+The builder workflows (`build.yml`, `package.yml`, `docker.yml`, `helm-package.yml`) are reusable stages. Only `release-publish.yml` has release write credentials. Development builds retain their artifact names and download channel. Daily development builds now select Linux only; macOS/Windows development artifacts are refreshed by an explicit manual build, and both remain mandatory for a completed release candidate. Tag pushes no longer start a second compilation.
+
+## Freeze and build
+
+Select a reviewed source commit whose Cargo version equals the intended final version. Finish exact-source CI before dispatching the candidate. The candidate workflow itself must run from upstream main. Unrelated main commits do not require rebuilding an accepted source.
+
+```bash
+gh workflow run release-candidate.yml --ref main \
+  -f version='<version>' -f source_sha='<full-source-sha>'
+```
+
+The initial job records the source and workflow SHAs, release recipe, dependency lock, exact stable Rust version, Console tag/asset/SHA-256, CLI assets, previous stable release and validation plan. All platforms consume that record; none independently follows `latest`. The source commit must contain the same reviewed release recipe as the dispatcher. Relevant recipe changes require a new candidate; unrelated source changes on main do not invalidate the frozen record.
+
+Linux is built first. Each archived executable must display the final version, expected target, source commit and compiler version, then start natively, serve the Console, and pass an authenticated S3 bucket/object round trip. The upgrade lane runs the existing pinned compatibility matrix plus the stable version frozen at candidate creation. It compiles the harness and runs the accepted executable; it does not rebuild a substitute server. A zero-test invocation fails.
+
+The Linux manifest is partial evidence and cannot authorize publication. Download the exact artifacts for field acceptance. Record the source, manifest digest, run URL and actual tested binary digests in backlog. Required field acceptance includes Scanner/Heal and multi-pool behavior, major features, memory, high-concurrency 503s, performance against the agreed baseline, previous-version data integrity and upgrade recovery. The agreed stability duration is a release-specific requirement, not an implicit workflow default.
+
+## Complete the accepted candidate
+
+After the Linux report passes, dispatch `release-complete.yml` with the exact digest printed by the candidate run. The `release-linux-acceptance` environment is the operator gate. Configure its protection and allowed main branch in repository settings; a typed digest and report identify what is being accepted, while the workflow independently revalidates automated evidence.
+
+```bash
+gh workflow run release-complete.yml --ref main \
+  -f candidate_run_id='<run-id>' \
+  -f linux_manifest_sha256='<accepted-linux-manifest-sha256>' \
+  -f acceptance_report='https://github.com/rustfs/backlog/issues/<issue>#issuecomment-<comment>'
+```
+
+macOS and Windows now build and run the same native checks. Packages and images wrap the accepted Linux binaries. DEB/RPM extraction must reproduce the recorded binary digest. Both OCI variants are checked on amd64 and arm64 and scanned before sealing. Vulnerability scans retain the repository's report-only policy; scanner execution errors still fail the stage. Image OS packages are resolved during packaging, then the actual resulting OCI bytes are accepted and preserved; this is not a promise of reproducible package-manager output.
+
+The Helm chart is tested and packaged before sealing, with chart and application versions equal to the final product version. Full certification requires every platform and upgrade case from the original plan. The seal includes artifact hashes, raw evidence, source/input identities, acceptance report, checksums, SBOM and provenance. Successful Linux receipts remain valid while desktop results are added because each receipt binds its own exact archive and executable, the frozen plan, candidate identity and trusted producer.
+
+Native smoke checks are not a substitute for Console UI and rc acceptance. Complete the release skill's UI/client checks against these exact artifacts, including desktop checks applicable to the release, before asking for final publication approval.
+
+## Approve and publish
+
+Review the complete run and final `release-manifest.json`. Human approval binds its SHA-256, source and version. A changed manifest requires renewed approval. No source version bump, compilation, package generation or image build occurs during publication.
+
+```bash
+gh workflow run release-publish.yml --ref main \
+  -f complete_run_id='<successful-completion-run-id>' \
+  -f manifest_sha256='<approved-final-manifest-sha256>'
+```
+
+The publisher downloads the artifact from the exact successful main workflow run, checks GitHub's artifact digest, recomputes file hashes and reruns complete certification. It creates an annotated tag whose message binds the source and manifest. An existing tag or asset with different bytes is a hard failure; tags are never moved and uploads never clobber assets.
+
+Versioned GitHub assets, R2 objects and Docker Hub/GHCR/Quay manifests are uploaded and read back before the Release becomes public. OCI promotion uses `--preserve-digests`; registry conversion fails rather than silently accepting a new image. R2 creation uses atomic `If-None-Match: *`. The small evidence bundle persists with the public Release after Actions artifacts expire. Provenance is descriptive, not a claim of cryptographic attestation.
+
+Publication uses a per-version lock and a shared channel lock, both without cancelling an active run. Stable channels advance only after versioned delivery succeeds. GitHub Latest acts as a monotonic marker during partial channel updates, so an older retry cannot downgrade Docker tags, R2 aliases or installer pointers. Prereleases do not advance stable channels. Helm publishes the already accepted chart after versioned images exist. GitHub's legacy `*-latest.zip` download names remain aliases of the accepted bytes; they become default downloads only when GitHub Latest advances.
+
+Cross-registry publication is not atomic. A channel job can fail after some verified destinations advance. Resume the same run/seal: matching destinations are reused and conflicting ones stop the workflow. Retrying never recompiles. Do not claim complete publication until the channel receipt and all public endpoints are verified.
+
+## Failure and retention
+
+- Infrastructure failure: rerun failed jobs in the same run. Frozen inputs, successful platform/package/image artifacts and completed seals are reused. Missing or expired artifacts fail closed.
+- Product or build-input change before tagging: create a new candidate run and repeat affected acceptance. Do not mutate the old candidate.
+- Failure after tagging: resume publication of exactly that seal. A code fix requires a new patch version; never move the tag.
+- New main commits: retain evidence for unchanged source, recipe and inputs. Recheck only affected boundaries; do not restart the entire matrix because an unrelated PR merged.
+- Artifacts are retained for 30 days while awaiting acceptance. Public-repository Actions artifacts and staging identifiers are not confidential storage. Preserve important failure evidence in task-owned storage and backlog.
+
+## Migration and workflow maintenance
+
+Finish any in-flight legacy tag release, including its downstream Docker/package/Helm jobs, before enabling this cutover on main. Existing tags and Releases retain their identities. Do not feed a legacy public preview binary into the new promotion path: it embeds a different version and was not built from the frozen-input contract.
+
+All workflow responsibilities, triggers and schedule ownership remain registered in `.github/scheduled-validations.json`. The migration does not re-enable workflows disabled in GitHub. PR checks, cache warming, nightly development builds, functional chains, lab tests and monitoring retain their distinct purposes; shared source or cache does not make different feature/platform tests redundant. The watchdog allocates a runner only for relevant unsuccessful scheduled/chained runs, while its registry still determines ownership.
+
+Run `actionlint`, the release contract suite and the workflow registry validator after changes. The Security Audit workflow also exercises actual GitHub artifact transport, DEB/RPM package extraction, both multi-platform OCI builders, local registry promotion and archive scanning. Native packaging jobs run only for relevant changes or a manual audit. Their payloads are explicit transport fixtures, not product release acceptance. See the [release skill](../../.agents/skills/rustfs-release-publish/SKILL.md) for field acceptance, human confirmation and post-release follow-up.

 The committed policy is `enforced`: ordinary Rust changes select their reverse dependency closure plus the fixed core inventory, and unrelated changes can omit the Connect specialization. Package-owned fixtures, non-Rust inputs, build scripts, manifests, unknown paths and non-PR events retain full validation. Existing documentation and isolated E2E scopes remain conservative. Changing a PR's own policy cannot authorize skipping its base revision's requirements. A base planner predating the current workflow contract clears all narrower outputs and selects the full matrix. Set the policy back to `shadow` to retain proposed selections while restoring full ordinary-code execution; do not remove core inventories or negative checks as a rollback.

+Stable installation-version alignment has one content-based exception in enforced mode: literal version fields in `flake.nix`, `helm/rustfs/Chart.yaml` and `rustfs.spec`, plus a standard prepended RPM release note, can use the documentation scope. Quick Checks, Typos, CLA and the required aggregate remain. The planner compares both complete Git blobs and requires ordinary non-executable files; changes to build logic, CLI pins, chart settings, RPM macros or older changelog entries retain the full gate. New/deleted files, mode changes, prerelease syntax, unavailable history, shadow rollout and explicit full-path policy overrides also retain full validation. Product-code changes in the same PR retain their normal dependency and core coverage, and main pushes, merge groups, scheduled and manual runs still validate the complete candidate. This exception does not establish artifact availability or authorize a release; post-release checks still verify the published target before updating defaults.
+
 `Test and Lint` remains the required aggregate name. Every verification producer and consumer is a direct dependency. The verifier accepts only the effective plan's exact expected success/skipped outcomes; failure, cancellation, missing results, extra jobs or a plan for a different candidate fail. Quick Checks and CLA retain their separate required names.

overtrue	9d513cffe9	test(e2e): update smoke selection for reference-binary unit tests	2026-11-11 11:25:30 +08:00
overtrue	c5afd3738c	chore: merge gateway/integration into gw/T3-reference-binary	2026-11-11 10:33:04 +08:00
Chris An	fc09148f08	chore(gateway): record ignored microbenchmarks merged from main (#9290 ) chore(gateway): record the ignored microbenchmarks merged from main main added three throughput microbenchmarks that are ignored by design (#9217): one each in rustfs-checksums, rustfs-rio and rustfs-utils. The test-count ratchet treats a higher ignored count as a failure until the row is raised, so raise those three rows to 1 and tighten the test rows to the merged tree with --update.	2026-11-10 21:30:34 -05:00
rustfs-cla-assistant[bot]	c9e1464a2a	Merge remote-tracking branch 'origin/main' into gateway/integration	2026-11-11 02:06:08 +00:00
Chris An	0e3028d29e	ci(gateway): make the test-count ratchet a floor, not exact (#9278 ) ci(gateway): make the test-count ratchet a floor instead of an exact baseline Tests below a row still fail; tests above it, a member without a row and ignores below the row now pass with a note. Ignores above a row still fail. Adds contract tests wired into make script-tests.	2026-11-10 20:53:06 -05:00
overtrue	6b44869b4f	test(e2e): allow a pinned release binary as differential reference side RUSTFS_E2E_REFERENCE_BINARY makes side A of the dual-stack differential a released rustfs binary, started without RUSTFS_S3_STACK. A missing, non-file or non-executable path fails the run instead of falling back to the same-binary mode. The report records which side is the reference and each side's --version output.	2026-11-11 09:44:12 +08:00

Patrick Wicki	ba3e0e1546	fix(admin): keep measured bucket usage when the overlay is unconverged (#9243 ) The single-process usage overlay clears usage_snapshot_complete when it holds counts it cannot reconcile with the persisted snapshot, for example writes into a bucket that has no verified baseline. The admin datausageinfo path then judged the overlaid document as structurally incomplete and replaced it with an empty one, hiding every bucket the scanner had measured. Because each write restarts that bucket's scanner fence, a continuously written bucket kept the whole response empty indefinitely. Decide whether the persisted snapshot is usable before the overlay is applied, and report overlay-induced incompleteness as a non-converged snapshot instead, as is already done for buckets the scan never reached (rustfs#5806).	2026-11-10 17:52:06 -05:00
