# nanodock - Pre-push hook

# Runs the full quality gate before pushing to remote.

# This mirrors the CI checks so issues are caught locally before a PR.

#

# Install: copy this file to .git/hooks/pre-push (or run scripts/install-hooks.sh)

#          chmod +x .git/hooks/pre-push  (Linux/macOS)

#

# What it checks:

#   1. cargo fmt --check   - formatting

#   2. cross-target clippy - lint violations across Linux + Windows targets

#   3. cargo test          - all tests pass

#   4. cargo bench --no-run - gungraun benchmarks compile

#   5. cargo build         - library compiles

#   6. cargo doc           - documentation builds with CI rustdoc flags

#   7. cargo deny check    - dependency audit (if cargo-deny is installed)
