# release-check.sh — local gate for the manual release fallback.
#
# Usage:
#   ./scripts/release-check.sh X.Y.Z
#
# The standard release path is the `release.yml` GitHub Actions
# workflow (see docs/RELEASE.md). This script reproduces the
# `prepare` job's quality gate locally for the rare case where
# the workflow is broken and someone has to ship by hand.
#
# Runs:
#   - cargo fmt --check
#   - cargo clippy -D warnings (all targets)
#   - cargo test
#   - cargo package --allow-dirty
#   - argument is a valid X.Y.Z string
#
# Does NOT bump Cargo.toml, write commits, or push anything. After
# this passes, the manual fallback in docs/RELEASE.md takes over.
