… tag check, pin npm Closes Gitlawb#234. workflow_dispatch runs the selected ref's YAML and npm trusted publishing matches on the workflow filename, not the ref, so a dispatched non-main ref could reach the OIDC publish with no approval. Declare environment: release on all three publish jobs (npm-publish, docker, docker-manifest) so the environment's deployment-branch rule gates every publish surface, not just the OIDC one. Also close the two residuals the issue carries: the release-tag case glob was right-unanchored (accepted v1.2.3.4.5, v1_x, v1-any-branch-name, bare v1), now an extglob v+([0-9]).+([0-9]).+([0-9]); and the OIDC publish ran npm@^11.5.1, a floating range, now pinned to npm@11.19.1. The environment itself must exist with a deployment-branch rule limited to main (and required reviewers if desired) for the gate to bite; npmjs.com can also scope each package's trusted publisher to environment "release" for a registry-side check that survives a workflow edit.
Closes Gitlawb#271, closes Gitlawb#238. actions/checkout resolves an unqualified ref as a branch before a tag, so a branch named v0.7.1 shadows the tag and the release builds unreviewed content. Qualify all four release-tag checkouts as refs/tags/..., which takes checkout's unconditional tag path. docker-manifest applied :latest and :X.Y unconditionally, so a backfill of an older tag repointed them at older code. The manifest now always publishes the immutable :X.Y.Z and applies the moving tags only when the resolved version is not older than the registry's latest release. The same shape existed on the npm side: publish moves the latest dist-tag to whatever it publishes, so a backfilled older version would have stolen it; older backfills now publish under the backfill dist-tag instead. The manifest also asserted nothing about the digest set it stitches, so a wrong-arity or misnamed artifact would ship under :latest. Assert two digests of 64 lowercase hex chars before imagetools create. Extend the resolver test to pin both publish steps byte-for-byte and to reject any unqualified tag-checkout ref, so these guards cannot regress silently.
… provenance Two residuals from review of the dispatch-publish surface: - environment: release only covered the three registry-publish jobs. Declaring it on all eight jobs means a dispatch of unmodified YAML on a non-main ref is denied by the environment's deployment rules before any step runs. - The resolver shape-checked vX.Y.Z but did not prove the tag was produced by the release flow. A write-access user could plant a v99.99.99 tag on unreviewed content and dispatch a backfill against it. In CI (GH_TOKEN present) the resolver now requires a GitHub release for the tag and a main...tag compare status of identical or behind, so the tag's commit must already be reachable from main.
…okup errors Second adversarial pass found two residuals: - The provenance check compared main...<tag> with an unqualified refname, the same branch-shadows-tag ambiguity the refs/tags/ checkout prefix was added to avoid. Resolve the tag through commits/refs/tags/<tag> to a commit SHA and compare that instead. - npm view ... || true mapped every lookup failure to "no latest", so a registry outage during an older backfill would publish under --tag latest and move the dist-tag backward. E404 still means first publish; any other failure now aborts before a dist-tag is chosen.
…lose the test gap Third adversarial pass: - Provenance now also requires the release to be authored by the release automation account, so a hand-created release on a valid tag does not qualify for backfill. - The npm dist-tag decision is per package. A partial publish can leave platform packages ahead of the wrapper, and a single lookup on @gitlawb/gl would then downgrade an ahead package's latest tag. - The environment gate test now emits one line per job and marks jobs with no declaration MISSING, so a job added without environment: release can no longer pass silently.
… release pointer GitHub's latest-release pointer is operator-mutable and is not a bound on what :latest serves. List the package's versions on ghcr and refuse to move :X.Y or :latest below the newest X.Y.Z tag there. A 404 means the package does not exist yet, so the first publish applies all tags; any other lookup failure aborts. The version filter is grouped with || true so an empty list does not trip pipefail.
The npm backfill republishes GitHub release assets, which are mutable for anyone with contents: write. Require every asset on the release to have been uploaded by github-actions[bot], matching the release-author check. Not a hard bound, but it removes the direct edit path and leaves a review signal when a hand-uploaded asset blocks a backfill.
… end The provenance checks ran at resolve time but the consumers re-resolved mutable names afterward, leaving a move-the-tag or replace-the-asset race: - Checkouts now use the commit SHA the resolver emitted (tag_commit), falling back to the qualified tag ref. - The resolver captures the release's name/id asset pairs once, checks all uploaders against them, and the lay-in step downloads by asset id. An asset deleted and reuploaded between resolve and download gets a new id and fails closed. - The npm-publish comment now names the third trusted-publisher component (environment), which is what binds the OIDC token to the gate.
…inputs locally - release-binaries and web-sync now resolve the release tag and check out the verified commit SHA, closing the tag-move race on the job that produces the release assets, not just the jobs that consume them. - homebrew-bump resolves the tag, downloads the tarballs by captured asset id, and computes sha256 locally instead of trusting the mutable *.tar.gz.sha256 sidecar assets. - The step pin now covers the lay-in, formula, and release-tag checkout blocks so edits to the trust boundary force a deliberate fixture update.
Reachable-from-main alone accepts a tag moved to any other main commit. The release object records its creation-time target_commitish, so require tag_commit == release.targetCommitish: a moved tag now fails closed, and the SHA emitted for checkouts is provably the released commit.
The matrix includes windows-latest where run: defaults to pwsh, and the resolver body is bash.
Release asset names are attacker-controlled text. A crafted name carrying whitespace could smuggle a fake uploader into the third positional field and pass the automation-only check. Emitting names base64-encoded keeps each record in three real fields and makes the name-to-id lookup immune to injection.

Greptile SummaryThis PR hardens release and backfill publishing by validating release provenance, pinning verified commits and release assets, protecting every release job with a GitHub Environment, and preventing older versions from replacing the primary moving tags.
Confidence Score: 4/5The PR should not merge until GHCR minor-line tags can advance independently of the global latest version. A backfill newer within an older minor line publishes its immutable image but cannot update that line’s X.Y tag whenever any newer global release exists, leaving minor-line consumers on stale images. Files Needing Attention: .github/workflows/release.yml
|
| Filename | Overview |
|---|---|
| .github/workflows/release.yml | Adds environment gates, provenance-aware checkouts and downloads, and forward-only publish logic; the GHCR global maximum incorrectly controls minor-line tags. |
| scripts/resolve-release-tag.sh | Enforces exact release tags and validates release author, asset uploaders, tag target, and main ancestry before emitting immutable identifiers. |
| scripts/test-resolve-release-tag.sh | Adds provenance test cases and pins security-sensitive workflow blocks, but does not behaviorally test independent GHCR minor-tag advancement. |

- serialize all release runs under one concurrency group; the ref-keyed group let dispatches from different refs interleave
The docker-manifest rel step now emits image= the same way the docker job's does, and both manifest steps consume steps.rel.outputs.image instead of recomputing the lowercase ghcr path. The three whole-workflow awk scanners now ignore everything before jobs: and flush at job boundaries, so an `on.push.branches` list item can no longer open a pseudo-step that swallows top-level YAML, and a step record can no longer absorb the next job's header lines.
Review of the follow-up diff found the structural assertions could be satisfied or evaded without the behavior they guard: - the gh stub now pipes a fixture response through real jq with the caller's own -q on every arm, so a resolver that hardcodes its expected fields is detected - the moving-tag scan keys on the outcome (a push mechanism plus a mutable-tag reference in decommented step text) and requires the event+ref guard on the carrier's if: line, instead of binding one argv spelling and accepting comment-borne guard text - a new assertion pins the on.push.branches / workflow_dispatch triggers, which no step-level check could see - the npm check detects install/i and -g/--global variants, requires a non-empty install set, and reads the pin comparison from code, not comments - the stale-reads scan covers first step lines, job-level env/if lines, and jobs without a resolver step - the resolver test asserts the GHAE heredoc terminator, clears ambient GH_TOKEN/GITHUB_REPOSITORY on non-stub calls, and prints the captured resolver stderr when a pass-expected case fails - sha() exits on a failed download, since errexit is off inside its command substitution and a truncated file would otherwise be hashed
The event gate alone cannot bound a stale run: a re-run of an older push run replays its stored needs outputs under the original event and ref, and would move :latest and :X.Y backward to that run's version. The gated step now derives the newest published release from the live releases list (contents:read, drafts and prereleases excluded) and refuses when this run's version is not the maximum. The check reduces to VERSION == max, because the run's own release already exists by the time the step runs. The all-steps assertion now requires the carrier to carry the floor as well as the event+ref guard, and the red-check spec gains a gated-but-floorless carrier mutation to prove the clause binds.

Failing resolver runs print no diagnostic. resolve-release-tag.sh writes all ::error:: lines to stdout, and Line 143 captures stdout in prov-stdout while these handlers echo only prov-stderr.

Summary
Every job in
release.ymlnow runs inside areleaseGitHub Environment, and the manual backfill path proves provenance before publishing: the tag must be exactvX.Y.Z, must point at the commit its release was created against, and must sit onmain, and the release and its assets must come from the release automation. Downloads go by immutable asset ID and checkouts pin the verified commit, so nothing in the publish path re-resolves a mutable name.Motivation & context
The
workflow_dispatchbackfill path added in #235 reaches three publish jobs (npm-publish,docker,docker-manifest) with no approval gate, a tag glob loose enough to acceptv1-any-branch-name, and moving-tag republish logic that can pushlatestandX.Ybackwards. A write-access collaborator can also dispatch a ref whose own copy of the workflow drops the gates, so this PR proves in-repo everything that can be proven: the tag, its commit, the release author, and the asset bytes.Refs #234
Closes #238
Closes #271
Kind of change
What changed
environment: releaseon all eight jobs, so every external write (npm OIDC, ghcr, release assets, Homebrew/web pushes) hangs off one protected environment. The test enumerates jobs out ofrelease.ymlitself, so a future job added without the gate fails CI.scripts/resolve-release-tag.shnow requires exactvX.Y.Z, and in CI resolves the release end to end: release authored bygithub-actions[bot], all assets uploaded by it, the tag's commit equal to the release's recordedtarget_commitish, and that commit identical to or behindmain. It emits the verified commit SHA and an asset name-to-ID map with names base64-encoded so a crafted asset name cannot shift the fields.refs/tags/<tag>(ci(release): unqualified checkout ref lets a branch shadow the release tag, so a release builds from unreviewed branch content #271), and the publish jobs check out the resolver's verified commit rather than re-resolving the tag.npm-publishandhomebrew-bumpdownload release assets by the captured IDs instead of by name, and the Homebrew formula hashes the tarballs locally rather than trusting the mutable.sha256sidecars.docker-manifestalways publishes the immutable:X.Y.Z, and a separateMove floating tagsstep applies:latestand:X.Yonly onpushruns targetingrefs/heads/main. Aworkflow_dispatchbackfill republishes the immutable tag and moves no pointer; after a backfill that is genuinely newest in its minor line, advance:X.Yby hand. The step also floors the move against the releases list before touching the tags: a re-run of an older push run replays its stored outputs, so the step refuses when its version is no longer the newest published release. On the push path the tags only ever advance because release-please versions are monotonic onmain. Digest-file arity and name shape are validated. (ci(release): docker backfill repoints :latest/:X.Y backward, and manifest publishes any digests present #238)npm-publishdecideslatestvsbackfillper package against that package's owndist-tags.latest, fails closed on registry errors other than E404, and installs an exactnpm@11.19.1instead of a range.release-binariesresolver step declaresshell: bashbecause the matrix includeswindows-latest.npm --versionmatches the pinned11.19.1, so a drift or shadowed install fails the job instead of running a different npm on the OIDC path.steps.rel.outputs.*rather than re-reading release-please's outputs, so every consumer sees the version and tag the resolver verified.sha()helper now reports on stderr, and a failed download exits instead of hashing a truncated file; previously the::error::line and the download failure were both swallowed by command substitution and the step failed silently or published a wrong checksum.New concepts
Environment-scoped trusted publishing. npm's trusted-publisher match can include the GitHub Environment the OIDC token was minted under, not only the repo and workflow filename. That turns
environment: releaseinto a registry-side boundary for npm: a dispatched ref that deletes the stanza mints a token without the environment claim, and npm rejects it. GHCR'sGITHUB_TOKENpath has no equivalent, which is why the repo-side setup below still matters.How a reviewer can verify
The suite runs the real resolver against malformed tags, then replays the CI provenance path against a stubbed
gh(bot vs collaborator release author, bot vs collaborator asset uploaders, moved tags, crafted asset names). It also extracts the security-relevantrun:blocks out ofrelease.ymlverbatim and compares them to a pinned fixture, so the publish logic cannot drift silently.The suite also asserts, over every step in
release.yml, that exactly one step pushes the moving tags, that it carries thepush/refs/heads/maingate and the live releases floor, that the workflow still triggers onpushtomainandworkflow_dispatch, that no step reads the retired GHCR versions endpoint, that each npm install step asserts its own pin, and that no post-resolve step re-reads release-please outputs at any level. Theghstub answers on the full command line and pipes fixture responses through realjqwith the caller's own-qexpression, so dropping| @base64, therefs/tags/qualification, or a hardcoded provenance field goes red.Before you request review

The in-repo half of the boundary is done. The load-bearing half is repo configuration this diff cannot express:
releaseenvironment under Settings > Environments with a deployment branch rule admitting onlymain, and no required reviewers or wait timer.release. That is what turns theenvironment:line into a hard boundary for npm.releaseenvironment secrets; delete the repository-level copies in the merge sitting. A dispatched branch can read repository secrets from any workflow it brings, so the old values are treated as captured.Residual: a write-access collaborator can already push to GHCR with
