# Test-target compile gate: blocks a push whose test targets do not build.

# Activate in a fresh clone (one-time):
#   git config core.hooksPath scripts/githooks
#
# Bypass for a work-in-progress push: git push --no-verify
#
# `cargo check` and `cargo clippy` both compile only the lib and bin targets, so
# a break confined to `tests/` or a `#[cfg(test)]` module is clean under both and
# lands unnoticed (the sqlx 0.9 upgrade shipped exactly that way). `--no-run`
# builds every test target without running them, which is the cheap half of the
# suite and enough to catch a compile break. Tests still run separately.
#
# `--workspace` is load-bearing: default-members is src-tauri alone, so a bare
# `cargo test --no-run` would skip core, db-sqlite, go-mcp, and got.
