📝 Walkthrough

Walkthrough

Adds a GitHub Actions workflow that runs on pushes to main and pull requests, sets workflow concurrency and read-only permissions, and executes a Go build, lint, and test job.

Changes

CI Workflow

Layer / File(s)	Summary
CI workflow definition .github/workflows/ci.yml	Defines the workflow triggers, concurrency behavior, read-only permissions, and the test job that checks out code, sets up Go, installs goimports, and runs build, lint, and test.

Estimated code review effort: 2 (Simple) | ~10 minutes

Poem

A rabbit hopped through CI tonight,
With builds and tests all running right.
Main branch now hums, pull requests too,
goimports joins the clover dew.

Pull request overview

Adds a GitHub Actions CI workflow to run core Go build/lint/test checks on PRs and main branch pushes, aligning automated CI with the repository’s existing local verification commands (go build, make lint, make test).

Changes:

• Introduces a ci workflow that builds the vev binary, runs make lint, and runs make test (race-enabled).
• Pins actions/checkout and actions/setup-go to specific SHAs and sets minimal permissions (contents: read).
• Adds concurrency cancelation and a job timeout to reduce redundant CI runs.

Verify each finding against current code. Fix only still-valid issues, skip the

Inline comments:
In @.github/workflows/ci.yml:
- Around line 21-26: The workflow is still pinned to older major versions of
actions/checkout and actions/setup-go, so update the uses entries in ci.yml to
the current majors and replace the SHA pins with the matching new commit SHAs.
Keep the existing step structure and inputs the same, but refresh the references
for the checkout and setup-go actions so the workflow uses the latest supported
versions.
