 - CI security scanning now uses GitHub Marketplace actions (`securego/gosec` and `golang/govulncheck-action`) instead of manual tool installation, improving reliability and caching.
 - CI setup compatibility fix: gosec scanner now references the correct public action source (`securego/gosec`), resolving action clone failures in Gitea runners.
 - Code formatting validation added to CI pipelines: pushes and pull requests with code not matching `go fmt ./...` output will be rejected.
+- Applied `go fmt` normalization to core tests (`list_test.go` and `track_test.go`) to satisfy the new formatting gate.
 - Dependencies updated to resolve security vulnerabilities: `cloudflare/circl` to v1.6.3, `go-git/v5` to v5.17.0, `golang.org/x/crypto` to v0.49.0, and `golang.org/x/net` to v0.52.0.
 - CI workflows now include explicit caching for Go modules and build artifacts to reduce pipeline execution time.
 - Security hardening: file and directory creation now uses restrictive permissions (`0o750` for directories, `0o600` for files) instead of world-accessible defaults. Executable wrapper scripts are created with restricted permissions and then explicitly made executable via `chmod`.
