-# Deprecated compatibility entry point. The ecosystem is multi-repository;
-# use check-module-release-parity.sh for the canonical name.

-# Workspace release parity: verify every ecosystem module graycode requires
-# resolves to a published, reachable commit. This catches go.mod pins to
-# versions that do not exist. Run from the graycode repo root.
-#
-# Note: it deliberately does NOT compare against sibling HEAD ancestry —
-# CI clones the siblings as shallow (depth-1) checkouts, so older pinned
-# commits are not present in their history and ancestry checks would
-# falsely report AHEAD. Resolution (go mod download) is the robust signal.
