# Publish one workspace crate to crates.io, tolerating "already uploaded".
#
# Usage: scripts/ci-publish-crate.sh <crate-name>
#
# `cargo publish` (1.66+) already waits for the crate to be available in the
# sparse index before returning, so no extra polling is needed here. The
# pre-check against crates.io's JSON API is only to skip the whole compile
# step when this version is already published (e.g. re-running a failed job).
#
# Robustness vs prior fragile patterns: tolerates "already exists on
# crates.io index" / "already uploaded" cargo errors so re-runs of a
# release after a partial publish succeed instead of aborting at the
# first already-published crate.
