v1.0.0

Initial public release.

A small, fully-auditable composite GitHub Action that keeps a fork branch in sync with an upstream repository — the entire implementation is one readable scripts/sync.sh (no Node runtime, no vendored dist//node_modules).

Features

• merge / rebase / reset sync modes, dry_run, private-upstream token support
• script-injection-safe (inputs via env), strict repo/branch validation, tokens via http.extraheader (never in URLs), repo-local git config
• outputs: has_new_commits, commit_count, upstream_sha

Docs

• Cloudflare-Worker fork auto-deploy recipe
• click-by-click least-privilege GitHub PAT setup
