# Ruby version for both stages. Keep in sync with `.mise.toml` and the Gemfile's
# `ruby '4.0.7'` directive. The image ships Bundler 4.0.20, which the lockfile's
# BUNDLED WITH now pins, so no separate bundler install is needed.

# Platform assertion: no non-musl gem artifact may ship, enforced by the
# script docker/platform_assertion.rb. It replaces force_ruby_platform, added
# 2022-12 (commit 5b495933) because nokogiri shipped no precompiled musl gem
# then. That flag disabled platform resolution instead of verifying its
# result, so glibc artifacts could be installed unnoticed. Removal is safe
# now: ffi 1.17.4, google-protobuf 4.33.0, nokogiri 1.19.4 and pg 1.7.0
# publish musl-native platforms, now locked in Gemfile.lock. If this check
# fails, fix the offending gem's resolution instead of restoring the flag.
