# Validation gate: rebuilds the three dictionary DAWGs on every push/PR and checks they are
# non-empty. The build pins the published scrabble-solver builders (GOPRIVATE -> direct VCS
# fetch from this Gitea), so the on-disk format and letter indexing match the running backend
# exactly. Release artifacts (scrabble-dawg-<tag>.tar.gz attached to the Gitea release) are
# published from this output; see README.md. Inlined go run (no make/python dependency on the
# runner).
