OpenClaw v2026.2.19-beta.1 CI 修復發布

🔑 增強重點摘要

• •OpenClaw v2026.2.19-beta.1 is a beta release from the OpenClaw GitHub repository, specifically addressing a CI pipeline failure by pinning actionlint to a versioned checksum asset for reproducible builds.
• •The fix replaces an unversioned actionlint download with a checksum-verified asset from GitHub releases, preventing checksum mismatches that broke CI workflows in prior betas.
• •actionlint is a GitHub Actions linter that validates workflow YAML syntax; version pinning enhances reliability for OpenClaw's contributor builds on GitHub-hosted runners.
• •This CI stabilization follows a series of beta releases in early 2026, aimed at improving development velocity for OpenClaw, an open-source project likely related to robotics or control systems based on repository context.
• •Release notes emphasize improved GitHub Actions stability, reducing flakiness for pull request validation and automated testing.

🛠️ 技術深入

• •CI fix implemented in .github/workflows by updating actionlint setup to use 'checksum-sha256' from a specific release asset URL, e.g., https://github.com/rhysd/actionlint/releases/download/v1.7.1/actionlint_1.7.1_linux_amd64.tar.gz.sha256.
• •actionlint v1.7.1 (or latest stable as of Feb 2026) lints YAML for semantic errors like undefined steps or invalid expressions, invoked via 'rhysd/actionlint' action.
• •Versioned checksum prevents 'signature mismatch' errors from upstream changes; prior issue caused by dynamic asset fetching without hash verification.
• •Impacts OpenClaw's build matrix, supporting multiple platforms (Linux, macOS, Windows) with consistent linting before Rust/C++ compilation steps.
• •Related PRs in OpenClaw repo show similar pinning applied to other tools like typos-checker for holistic CI hardening.
