RunBack v0.1.3-alpha — try it on a failed GitHub Actions run

RunBack takes the URL of a completed, failed public GitHub Actions run, reconstructs its
historical workflow, job, matrix, runner and failed-step context, replays it locally with
act, and compares the remote and local failure evidence.

runback https://github.com/owner/repo/actions/runs/123456789

The goal is to replace repeated edit → push → wait → fail cycles with a local debugging loop:

failed run URL → local replay → SAME_FAILURE → edit → replay --step → verify

Try the alpha

Linux amd64 users can install the current release without Go or sudo:

curl -fsSL https://raw.githubusercontent.com/huanglinfei091-cmd/runback/main/scripts/install-release.sh | bash
~/.local/bin/runback doctor
~/.local/bin/runback https://github.com/OWNER/REPO/actions/runs/RUN_ID

Release and checksums:
https://github.com/huanglinfei091-cmd/runback/releases/tag/v0.1.3-alpha

The current alpha targets public GitHub.com repositories, completed failed runs, Ubuntu jobs,
and ordinary JavaScript/TypeScript, Python and Go workflows. Private repositories, services,
job containers, repository-local actions, secret-dependent jobs, Windows/macOS runners and
GitHub Enterprise are outside the validated scope.

What useful feedback looks like

Reply with a public failed run URL and the observed RunBack result:

• SAME_FAILURE
• DIFFERENT_FAILURE
• INSUFFICIENT_EVIDENCE
• REPLAY_BLOCKED
• EVIDENCE_UNAVAILABLE

For blocked cases, include Stage and Cause. Installation friction and unsuccessful reproduction
are useful evidence. Please do not post tokens, secrets, cookies, private source, complete
private logs or credentials.

The retained real cases cover Python mypy/pytest/Pyright, Go test, TypeScript compiler and
Vitest failures. The preregistered Vitest Case H initially remained
INSUFFICIENT_EVIDENCE; after a generic strict parser was added, the unchanged run produced
remote/local/matched 4/4/4 and SAME_FAILURE. These are project-owned evidence chains, not
external-user validation or a claim of complete GitHub Actions support:
