 ## 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.

-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.

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.

-- 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.

-## 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.

-git push origin "<preview-tag>"
-```
-
-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.

 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.

 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.

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.

 - 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.

-# Build and Release Workflow
-#
-# This workflow builds RustFS binaries and automatically triggers Docker image builds.
-#
-# Flow:
-# 1. Build binaries for multiple platforms
-# 2. Upload binaries to OSS storage
-# 3. Trigger docker.yml to build and push images using the uploaded binaries
-#
-# Platform scope:
-# - Development builds come from the nightly schedule and manual dispatch and
-#   cover the full platform matrix; they feed the dev download channel
-#   (artifacts/rustfs/dev on R2, the *-main-latest packages). Tags build the
-#   release matrix. Main pushes do not build: at the usual merge rate most
-#   per-merge builds were cancelled by the next merge before publishing
-#   anything, and the dev channel does not need per-merge granularity.
-#
-# Manual Parameters:
-# - publish: Publish binaries/releases for manual runs (default: false)
-# - build_docker: Advisory only; manual runs do not trigger Docker publishing
-# - platforms: Comma-separated platform IDs or 'all' (default: all)
+# Nightly development artifacts and reusable immutable-candidate builds.
+# Public release writes live exclusively in release-publish.yml. Candidate callers
+# select Linux or desktop and pin release inputs before any matrix starts.

-# Docker Images Workflow
-#
-# This workflow builds Docker images using pre-built binaries from the build workflow.
-#
-# Trigger Types:
-# 1. workflow_run: Automatically triggered when "Build and Release" workflow completes
-# 2. workflow_dispatch: Manual trigger for standalone Docker builds
-#
-# Key Features:
-# - Only triggers when Linux builds (x86_64 + aarch64) are successful
-# - Independent of macOS/Windows build status
-# - Uses workflow_run event for precise control
-# - Only builds Docker images for releases and prereleases (development builds are skipped)

-# Package Workflow - Build DEB/RPM packages
-#
-# This workflow builds DEB and RPM packages from pre-built Linux binaries
-# and uploads them to Cloudflare R2 and the GitHub release.
-#
-# Trigger:
-# - workflow_run: automatically package after "Build and Release" completes
-#   for a release tag (the mac/windows/linux binaries are already uploaded
-#   to the GitHub release before packaging starts)
-# - workflow_dispatch: manual fallback with a release tag and/or exact build run ID
-#
-# Flow:
-# 1. Resolve and validate the selected Build workflow run and source identity
-# 2. Download Linux binaries (x86_64-gnu, aarch64-gnu, x86_64-musl,
-#    aarch64-musl) from build artifacts
-# 3. Build DEB packages for amd64 and arm64, gnu and musl variants
-# 4. Build RPM packages for x86_64 and aarch64, gnu and musl variants
-# 5. Upload all packages to Cloudflare R2 and the GitHub release

+# 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.

 ## Release validation

+Post-merge and tag-driven; not a substitute for a PR gate. Every public publication exit consumes the release certification described here; this certification path is separate from the reusable CI artifact contract in [verification plans](ci-verification-pipeline.md), whose archives expire after one day and are never used as release certification.
+
+The versioned plan is `.config/release-validation-plan.json` (`schema_version=1`): release types, target OS/arch/ABI, supported features, a fixed harness SHA per lane, required case IDs, environment capabilities, timeouts, applicability conditions, and an explicit `upgrade_sources` list carrying the real artifact digests of the supported N-1/N-2 sources plus a stated rollback basis — compatibility and rollback are never invented or defaulted. `scripts/release/release_gate.py validate` expands and freezes `plan_sha256` and the required case set before reading results, then binds that plan, a `candidate.json` (product 40-character SHA, version, release profile, features, immutable deliverable locations with SHA256 and wrapped-binary SHA256, image digest) and the shared G01 evidence-envelope set (rustfs/backlog#2658) of one parent candidate batch, and writes machine JSON, JUnit and a summary. Within a batch the unique key is `(lane, platform{os,arch,abi}, case_id)`; the top-level run/attempt is the parent batch and the nested workflow run/attempt is the child workflow identity, and both are validated separately (workflow SHA and product build SHA are bound independently and need not be equal). Missing, duplicate or extra cases, stale attempts, wrong digests, wrong platforms, wrong harness SHAs, zero tests, cancellation, timeout, untrusted sources and any non-PASS required item block with classified errors; only a complete legal success returns 0. `verify-promotion` re-checks the exact bytes about to be published against the passed list and fails on a swapped package or an edited plan after verification. preview, prerelease and stable all require an explicit plan; preview may use the plan's smaller pre-declared set but never bypasses artifact identity and startup checks. development artifacts are explicitly uncertified and never touch official or latest channels.

+| GitHub Release draft → public | `build.yml` `publish-release` | `release-certification` success and per-asset `verify-promotion` |
+| Official R2 binary path `artifacts/rustfs/release/` | `build.yml` `promote-release-artifacts` | `release-certification` plus `verify-promotion`; the build job itself only writes `artifacts/rustfs/staging/<run>/<attempt>/` |

+| Official R2 package paths `packages/release` and `packages/latest` | `package.yml` `promote-packages` | `release-certification` and wrapped-binary `verify-promotion`; the package job only stages |
+| GitHub release package assets | `package.yml` `package` | `release-certification` and wrapped-binary `verify-promotion` before upload |
+| Helm chart repository (`rustfs/helm` push) | `helm-package.yml` `publish-helm-package` | `release-certification` plus the Docker workflow's image-promotion record bound to the same candidate |
+
+Downstream workflows fail closed when the trusted certification is absent: a manual dispatch without certification fails and pushes no official tag. Only results from the trusted verification sources listed in the plan (currently the `rustfs/s3chaos` `release-gate.yml` envelope runs) carry release authority; a PR-uploaded JSON set cannot certify a release. Retries reuse the same candidate, only the staged bytes are promoted (no rebuild-after-verify), and no downstream step re-resolves a mutable `latest`.
+
+Use an exact preview tag for an end-to-end release rehearsal. Manual dispatches are backfill/debug paths and do not prove the automatic `workflow_run` chain. The committed fixtures under `testdata/release-gate/` and the commands below are contract rehearsals of this orchestration; they are explicitly not product release evidence and not live verifier results.

 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.
