# .build.yml
#
# SourceHut build manifest for YAMS (single Linux target).
# Key points:
# - Compute version from Git ref (GIT_REF) at runtime; no manifest expressions.
# - Persist computed version into ~/.buildenv for subsequent tasks.
# - Add static build tags for search/badges.
# - Gate packaging steps so they only run on tag builds.
# - Fix CMake configure line continuation.
