build-cran-binaries/.crow/auto-apply-patches.yaml

# Auto-apply registry patches (issue #115, step 3 automation).
# Classifies `single_builds` failures and, for the top-N auto-proposable
# candidates by failure volume, writes the registry entries onto the reused
# `auto/registry-patch-proposals` branch and opens/updates a single PR.
# Nothing merges: the `trial-build-registry` pipeline is the merge gate, and a
# human reviews the PR. Novel source diffs / unknown signatures are never
# proposed. Global across platforms, so a single job -- no matrix.
#
# FORGEJO_TOKEN is used for both the branch push and opening the PR (no separate
# write-scoped secret needed). Register the `auto-apply-patches` cron in the crow
# UI, or run manually:
#   crow pipeline create --branch main \
#     --var auto_apply_patches=true devxy/build-cran-binaries
#
# The gate variable is `auto_apply_patches`, named after the pipeline: a manual
# run instantiates every pipeline in `.crow/`, so one without its own gate runs
# on *any* manual trigger in this repo. This one pushes a branch and opens a PR,
# so it must stay off unless it is what was asked for.
