 # Arch User Repository (AUR). The AUR is a community-driven repository for Arch Linux users.
 #
 # Workflow Overview:
-# 1. Validate: Builds and tests the package on both x86_64 and aarch64 (ARM64)
-#    architectures using clean Arch Linux containers.
-# 2. Audit: Checks Rust dependencies for known security vulnerabilities using 'cargo-audit'.
-# 3. Publish: If on the 'main' branch, it pushes the updated PKGBUILD and .SRCINFO to the AUR.

 # Security Best Practices:
-# - SHA Pinning: All GitHub Actions are pinned to a full-length commit SHA (e.g., v4.1.7 @ SHA)
+# - SHA Pinning: All GitHub Actions are pinned to a full-length commit SHA (e.g., v6.0.2 @ SHA)
 #   to ensure the code is immutable and protects against supply-chain attacks where a tag
 #   might be maliciously moved to a compromised commit.
 # - SSH Hygiene: Uses ssh-agent to keep the private key in memory rather than on disk.
