# .build.yml
#
# SourceHut build manifest for YAMS (single Linux target).
# Key points:
# - Compute version from Git ref (GIT_REF) or release channel (RELEASE_CHANNEL) 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 run for tag builds and for nightly/weekly channels.
# - Install Conan via pipx (or venv fallback), since Debian doesn't provide python3-conan.
