Exclude the Storybook browser projects from the snapshot test runs.

buildSnapshots runs bare pnpm test, which can select the @repo/storybook-config browser projects. The unit-test job in ci.yml excludes them with --project='!@repo/storybook-config*'. The snapshots job has no Chromium install step. If those projects run in that job, each pnpm test run can fail. The -u retry then fails the same way, and buildSnapshots throws Tests failed after updating snapshots. The workflow then never uploads the artifact.

Apply the same exclusion to every test run in the wrapper:

Suggested fix 
   const test = (args = []) => {
-    const result = spawnSync('pnpm', ['test', ...args], { stdio: 'inherit' });
+    const result = spawnSync(
+      'pnpm',
+      ['test', '--project=!@repo/storybook-config*', ...args],
+      { stdio: 'inherit' },
+    );

spawnSync does not use a shell, so the ! and * in the project pattern are passed literally. Alternatively, the snapshots job can install Chromium, but that adds a browser install to a job that already runs branch code.

Update the test-command wrapper used by buildSnapshots to pass the
--project=!@repo/storybook-config* exclusion on every pnpm test run, including
the snapshot-update retry; keep the pattern literal by preserving the existing
non-shell execution behavior.

Keep build code out of base-branch cache scope.

The snapshots job checks out the Renovate head (ref: ${{ needs.resolve.outputs.sha }}), runs ./.github/actions/setup-project, and then runs buildSnapshots. The workflow starts this job from pull_request_target, issue_comment, or workflow_dispatch. The last two run from the default branch. Runs in those contexts use the base-branch cache scope. contents: read and persist-credentials: false do not limit cache writes, because cache writes use runner runtime credentials rather than GITHUB_TOKEN.

Branch code can write to the cache through these paths:

  • setup-project runs pnpm build in the same job. This runs repository build code from the Renovate branch.
  • setup-project uses actions/setup-node with cache: pnpm. On a cache miss, its post step saves a cache built from the branch's pnpm install. release-please.yml also uses setup-project, so a later trusted run can restore a matching key.
  • spawnSync('pnpm', ['test', ...args], { stdio: 'inherit' }) passes the parent environment to the test process. That environment can include runner cache variables.

Changing only the build job to pull_request does not cover issue_comment or workflow_dispatch. Those runs still use the default-branch cache scope. Limit branch-code execution to pull_request runs, or remove branch-code execution from the other triggers.

The spawnSync filter below reduces what the test process inherits. It does not cover the pnpm build step or the setup-node cache save. Same-user processes can still read the parent environment, so this is partial mitigation only.

Partial mitigation: drop runtime variables from the test child environment 
   const test = (args = []) => {
-    const result = spawnSync('pnpm', ['test', ...args], { stdio: 'inherit' });
+    const env = Object.fromEntries(
+      Object.entries(process.env).filter(([key]) => {
+        return !/^(ACTIONS_|INPUT_)/.test(key);
+      }),
+    );
+    const result = spawnSync('pnpm', ['test', ...args], {
+      stdio: 'inherit',
+      env,
+    });

Review comment at @.github/workflows/renovate-snapshot-autofix.yml around lines
83 - 91:
Restrict the snapshots job that invokes buildSnapshots to pull_request runs, or
remove its branch-code execution from issue_comment and workflow_dispatch runs;
do not rely on filtering the test child environment, since setup-project also
builds branch code and can save package-manager caches.

When a Renovate pull request fails only because committed Vitest snapshots are
out of date, comment `/autofix-snapshots` on the pull request or add the
`autofix:snapshots` label. The snapshot autofix workflow runs the test suite in
update mode, refuses to commit non-snapshot changes, verifies the updated suite,
pushes the snapshot commit to the Renovate branch, and dispatches CI for it.
update mode on an immutable head SHA with a read-only token and no persisted Git
credentials. A separate job runs only trusted workflow code and treats the build
artifact as untrusted data. It accepts updates only to existing regular
`__snapshots__/*.snap` files containing only Vitest snapshot data assignments
(without JavaScript interpolation or extra code), verifies the branch still
points to the tested SHA,
creates a commit through the GitHub API, and dispatches CI. Inline snapshots in
test source, new snapshot files, and other changes require manual review. If the
branch moves, request a fresh run. Manual requests must dispatch the workflow
from the default branch and specify a `renovate/` branch.

The trusted artifact gate tests run automatically with `pnpm test`. For a
focused run, use `pnpm exec vitest run --project=ci-scripts`.
The workflow delegates branch resolution, test retries, artifact collection and
validated writes to `scripts/ci-snapshot-autofix.mjs`. The resolver and writer
load the trusted workflow revision; only the read-only build job loads branch code.

## SonarQube coverage

The unit-test CI command selects projects to exclude Storybook. With Vitest 5,
coverage include globs are relative to the selected package roots, so this
command also sets `--coverage.include='src/**/*.{js,jsx,ts,tsx}'`. The shared
workspace preset uses workspace-relative globs for unfiltered test runs.
Using those globs with `--project` produces an empty report even when all
tests pass.
The unit-test CI command selects projects to exclude Storybook and sets
`--coverage.include='**/src/**/*.{js,jsx,ts,tsx}'`. Vitest 5 matches coverage paths
relative to the first matching project root. With both package projects and the
root-level `ci-scripts` project selected, the glob must match both `src/...` and
`packages/.../src/...`. A package-only glob can produce file records without
measured lines even when all tests pass.

CI verifies that `coverage/lcov.info` contains source records and measured
lines before uploading it and again after downloading it for SonarQube. An
