# Merge gate for the auto-patch PR (issue #115, step 3).
# For each platform, trial-builds every registry entry the auto-patch branch
# ADDS (vs main) in that platform's own `reg.devxy.io/rpkgs/build-env-*` image,
# with the registry applied. A row with no new entries for its platform is a
# fast no-op. The pipeline is green only if every new entry builds, so it gates
# the PR before merge. Nothing is uploaded/archived/recorded.
#
# The repo uses no `pull_request` triggers, so this runs manually against the
# branch (or on a cron); point it at the auto-patch branch via `patch_branch`:
#   crow pipeline create --branch main --var trial_build_registry=true \
#     --var patch_branch=auto/registry-patch-proposals devxy/build-cran-binaries
#
# The gate variable is `trial_build_registry`, 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 starts a build per
# matrix row on both arches, which is far too expensive to fire by accident.
