rustfs-release-publish	Run the end-to-end RustFS console gate, version bump, preview validation, and final-tag publication pipeline. Use only when the user explicitly asks to release or publish a RustFS version (发版/发布).

RustFS Release Publish (preview-validated pipeline)

This skill orchestrates a full release. It wraps rustfs-release-version-bump (which only edits version files and opens the PR) with a mandatory preview-tag validation loop before the final tag is published.

Core design: version files never carry a -preview.N suffix. The preview suffix exists only in tag names. A preview tag creates a visible GitHub Release marked Prerelease and uploads versioned assets, but it never becomes GitHub Latest and never updates *-latest, latest.json, R2, Docker, or Helm channels. This works because the binary self-reports the git tag it was built from (build::TAG via shadow_rs, see rustfs/src/config/cli.rs SHORT_VERSION), and build.yml derives artifact names and preview classification from the tag name — Cargo.toml's version is only a no-tag fallback. Therefore the preview tag and the final tag can (and MUST) point at the exact same commit: what you validated is byte-for-byte the source that ships.

Pipeline shape:

check console main against its latest Release
  -> if ahead: publish console -> wait for Release asset + latest API
  -> bump RustFS version files to <target> (final version, ONE commit) -> merge
  -> tag <preview-tag> at that commit -> CI green
  -> verify preview Release assets -> run binary locally + console checks
  -> validate with latest rc client
  -> tag <target> at the SAME commit (zero delta) -> re-verify CI/release

On validation failure: fix lands on main via normal PR (version files are already at <target>, no new bump PR), then tag <preview-tag N+1> at the new main commit and restart from Phase 2.

Required inputs

• Final target version, for example 1.0.0-beta.10.
• Preview iteration N (default: next unused preview tag for that target; check with git tag -l '<target>-preview.*' after git fetch --tags).

If the target version is missing or ambiguous, stop and ask before doing anything (see the semver gate below).

Semver gate — confirm the target version before touching anything

Versions follow SemVer 2.0.0. Precedence reminder:

1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-beta.2 < 1.0.0-beta.11 < 1.0.0-rc.1 < 1.0.0 < 1.0.1 < 1.1.0 < 2.0.0

Numeric prerelease identifiers compare numerically (beta.9 < beta.10), not lexically — see semver.org spec item 11. Preview tags are internal validation tags layered on top of the target's prerelease channel — they are never themselves a deliverable version and never appear in version files.

Rules:

• A request like "发个版" / "release the next version" without an exact version string is ALWAYS ambiguous. Derive the current latest tag (git tag --sort=-v:refname | head), then ask the user to choose via AskUserQuestion with concrete candidates, e.g. from 1.0.0-beta.10: next prerelease 1.0.0-beta.11, promote to 1.0.0-rc.1, promote to stable 1.0.0. Never guess between these — they have very different meanings (channel promotion vs. iteration) and different CI classification consequences.
• After a stable X.Y.Z exists, the next version must state which component bumps: patch X.Y.(Z+1) for fixes only, minor X.(Y+1).0 for backward-compatible features, major (X+1).0.0 for breaking changes. If the user names a bump type but not a number, compute it from the latest stable tag and echo the exact resulting version back for confirmation.
• Echo the final confirmed version string verbatim in your first status report; every later phase must use exactly that string. If at any point the user's wording and the confirmed version diverge, stop and re-confirm.

Preview tag naming

• Use <target>-preview.N for every target, e.g. 1.0.0-beta.10-preview.3 or 1.1.0-preview.1.
• 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, Docker, or Helm publication is a pipeline failure.

Hard rules

• Version files (Cargo.toml, Cargo.lock, README, flake.nix, Chart.yaml, rustfs.spec) are bumped ONCE, directly to <target>. Never write a -preview.N suffix into any version file. If rustfs-release-version-bump is ever asked for a -preview version, that is a pipeline bug — stop.
• Preview Release assets are versioned and intentionally visible on the Releases page. Do not label them Latest or use them to update any latest distribution channel.
• Tags have no v prefix. Always annotated: git tag -a <tag> -m "Release <tag>".
• The final tag MUST point at exactly PREVIEW_HASH — the commit the validated preview tag points at. Never tag current main HEAD (commits merged after validation are unvalidated), and never create an extra version-bump commit between preview and final.
• 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. 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.
• Phases run in order; a failure in any phase blocks everything after it. After the fix lands on main, restart from Phase 2 with the next preview iteration against the new origin/main hash — do not resume mid-pipeline against a stale hash.
• If the release is abandoned after Phase 1 merged, main's version files claim a version that was never tagged. Either revert the bump PR or leave it to be overwritten by the next release — but tell the user explicitly and record the decision.
• User-facing status updates in Chinese; commits, PR titles/bodies, and tag messages in English. No hard-wrapping in commit messages, PR bodies, or documentation prose — one logical line per sentence/paragraph, let soft wrap handle display.

Phase 0 — Preflight

• git status --short clean; git fetch origin main --tags.
• gh auth status works; confirm you can view gh release list -L 3.
• Confirm the exact final target version with the user if not explicit.

Console release gate

Complete this gate before changing any RustFS version file or creating any RustFS tag. RustFS build.yml downloads the asset returned by repos/rustfs/console/releases/latest, so a successful Console build alone is insufficient.

1. Read the latest published Console tag and compare it with Console main:

CONSOLE_REPO="rustfs/console"
CONSOLE_LATEST=$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)
gh api "repos/${CONSOLE_REPO}/compare/${CONSOLE_LATEST}...main" \
  --jq '{status, ahead_by, behind_by, commits: [.commits[] | {sha, message: .commit.message}]}'

• ahead_by == 0: no merged Console change is waiting for release. Still verify the current latest asset using step 4, then continue to Phase 1.
• ahead_by > 0 and behind_by == 0: publish Console before continuing. Report the merged commits and select the next unused vX.Y.Z tag. Default to the next patch version when the changes are fixes or backward-compatible UI work; stop for confirmation if a minor/major bump is plausible.
• Any diverged history or behind_by > 0: stop and resolve the Console release baseline explicitly. Do not guess a range or publish RustFS.

2. Clone/fetch rustfs/console into a scratch directory and record its exact main commit. Before creating a tag, check for a v* tag or Release workflow already associated with that hash. If one is in progress, wait for it instead of creating another version:

CONSOLE_SCRATCH=$(mktemp -d)
gh repo clone "$CONSOLE_REPO" "$CONSOLE_SCRATCH/console"
git -C "$CONSOLE_SCRATCH/console" fetch origin main --tags
CONSOLE_HASH=$(git -C "$CONSOLE_SCRATCH/console" rev-parse origin/main)
git -C "$CONSOLE_SCRATCH/console" tag --points-at "$CONSOLE_HASH" 'v*'
gh run list -R "$CONSOLE_REPO" --workflow release.yml --commit "$CONSOLE_HASH" --limit 5

If no release exists or is running for CONSOLE_HASH, create the selected annotated tag at that exact hash and push it:

git -C "$CONSOLE_SCRATCH/console" tag -a "<console-tag>" -m "Release <console-tag>" "$CONSOLE_HASH"
git -C "$CONSOLE_SCRATCH/console" push origin "<console-tag>"

Console tags include the v prefix. Pushing the tag triggers .github/workflows/release.yml (🚀 Release). Remove CONSOLE_SCRATCH after the gate completes.

3. Find the exact tag run and wait for completion:

gh run list -R "$CONSOLE_REPO" --workflow release.yml --branch "<console-tag>" --limit 1
gh run watch -R "$CONSOLE_REPO" "<console-run-id>" --exit-status

4. Block until the published Release is non-draft, the latest endpoint returns the expected tag, and rustfs-console-<console-tag>.zip is uploaded, non-empty, and carries a sha256: digest:

gh release view -R "$CONSOLE_REPO" "<console-tag>" --json isDraft,isPrerelease,assets,url
test "$(gh api "repos/${CONSOLE_REPO}/releases/latest" --jq .tag_name)" = "<console-tag>"
test "$(gh api "repos/${CONSOLE_REPO}/releases/tags/<console-tag>" \
  --jq '[.assets[] | select(.name == "rustfs-console-<console-tag>.zip" and .state == "uploaded" and .size > 0 and (.digest | startswith("sha256:")))] | length')" -eq 1

Treat a missing/mismatched asset, digest, latest tag, or failed/cancelled workflow as BLOCKED. Do not start Phase 1 until the Console gate passes. Record CONSOLE_TAG, CONSOLE_HASH, Console run URL, and Release URL for the final report.

Phase 1 — Version bump to the final target (once)

• If main's version files already read <target> (e.g. this is a restart after a failed preview), verify with rg -n "<target>" Cargo.toml rustfs.spec helm/rustfs/Chart.yaml and skip to Phase 2.
• Otherwise invoke the rustfs-release-version-bump skill with the final <target> (NOT a preview version), full GitHub flow (commit/push/PR).
• Get the PR merged into main. Record the resulting main commit:

git fetch origin main
PREVIEW_HASH=$(git rev-parse origin/main)   # must contain the bump PR

PREVIEW_HASH is the single source of truth for the rest of the pipeline — report it to the user and reuse it verbatim in Phases 2 and 6. Both the preview tag and the final tag will point at it.

Phase 2 — Publish the preview tag

git tag -a "<preview-tag>" -m "Release <preview-tag>" "$PREVIEW_HASH"
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. Its latest-channel, R2, Docker, and Helm jobs must be skipped. Those publication paths run only after the final tag is pushed.

On a restart (N+1), refresh PREVIEW_HASH=$(git rev-parse origin/main) first — it must contain the fix — and re-report it.

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 Release publication jobs (create-release, upload-release-assets, and publish-release) succeed while update-latest-version is skipped.
• 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 preview-triggered Docker and Helm jobs are skipped. Preview validation covers the built RustFS binaries, embedded console, and rc compatibility; Docker image construction and Helm publication are deferred to the final tag because the Dockerfiles consume GitHub Release assets.

Phase 4 — Run the artifact locally, verify the console

Work inside the session scratchpad directory; never leave stray data dirs.

gh release download "<preview-tag>" -p "rustfs-macos-aarch64-v<preview-tag>.zip" -D "$SCRATCH"
cd "$SCRATCH" && unzip -o rustfs-*.zip
./rustfs --version        # must report the PREVIEW TAG (build::TAG), not the Cargo.toml version, plus expected short SHA
mkdir -p data
RUSTFS_ACCESS_KEY=rustfsadmin RUSTFS_SECRET_KEY=rustfsadmin ./rustfs ./data

Defaults: S3 endpoint :9000, embedded console :9001.

Checks (all must pass):

• ./rustfs --version reports the preview tag name and the short SHA of PREVIEW_HASH. Reporting <target> without the -preview.N suffix means the build did not embed the tag — treat as FAIL and investigate before proceeding.
• curl -fsS http://localhost:9000/health/ready returns ready.
• Startup log shows the embedded console being served (this was the regression that fix(release): require embedded console assets guards).
• Open http://localhost:9001 in the browser: login with rustfsadmin/rustfsadmin; dashboard renders without JS console errors; create a bucket, upload a file, download it back (byte-identical), delete the object and bucket. Keep the server running for Phase 5.

Phase 5 — Validate with the latest rc client

rc is the RustFS CLI client from https://github.com/rustfs/cli.

• Ensure the latest release is installed: compare rc --version against gh api repos/rustfs/cli/releases/latest --jq .tag_name; update via brew upgrade rustfs/tap/rc (or download the release binary).
• Point it at the preview server and run the command matrix, recording PASS/FAIL per command:

rc alias set preview http://localhost:9000 rustfsadmin rustfsadmin
rc ls preview/
rc mb preview/rel-check
rc cp <local-file> preview/rel-check/
rc stat preview/rel-check/<file>
rc cat preview/rel-check/<file>          # matches source
rc cp preview/rel-check/<file> ./out && cmp <local-file> ./out
rc cp -r <local-dir>/ preview/rel-check/dir/
rc find preview/rel-check --name "*"
rc share download preview/rel-check/<file> --expire 1h   # presigned URL fetchable via curl
rc rm preview/rel-check/<file> && rc rm -r --force preview/rel-check/dir
rc rb preview/rel-check
rc admin user list preview/
rc admin user add preview/ relcheckuser relchecksecret12
rc admin user remove preview/ relcheckuser
rc alias remove preview

• Any FAIL blocks the release. Afterwards stop the server and delete the scratch data directory.

Phase 6 — Publish the final tag on the validated commit

No second version bump, no release branch. The final tag goes on the exact commit the preview validated:

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>"

• CI rebuilds from the same source; the only changed input is the tag name, so the binary now self-reports <target>.
• 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.
• Optionally spot-check ./rustfs --version from a final-tag artifact — it must report <target>.

Output contract

Always report:

• Console gate result: previous/latest Console tags, whether merged changes required a release, CONSOLE_HASH, and Console run/Release URLs when a release was published.
• Target version, preview tag(s) used, PREVIEW_HASH (which both tags point at).
• Per-phase result (PASS/FAIL/BLOCKED) with key evidence: preview and final Release URLs, preview isPrerelease/isLatest state, final latest-channel state, console check results, and the rc command matrix.
• Any deviation from this pipeline and why the user approved it.
