# Re-index every slot without rebuilding anything.
#
# `weekly-rebuild-reindex` exists to run after `weekly-rebuild-missing`, so it
# depends on that workflow and shares its gate: triggering it manually also
# starts hours of package rebuilds. That is the wrong tool when only the index
# needs regenerating - after a bincraft release that changes how the index is
# written, for instance, where the objects in the bucket are already correct
# and only `PACKAGES*` is stale.
#
# This workflow does the index half on its own. It installs the latest bincraft
# release, republishes the generic and per-R-minor indexes for each slot, and
# purges the edge. No package is built.
#
# Trigger with the `reindex` variable set to `all` or to a single
# `<os>-<arch>`, e.g.
#
#   crow pipeline create devxy/build-cran-binaries --var reindex=all

variables:
  # A manual pipeline creation instantiates every file in .crow/, so the
  # default must match no matrix row.
