check / check (push) Successful in 16s
Follows sneak's ruling at #149 (comment). This repository now carries yarn 4.18.1 under .yarn/releases. The distribution's yarn only starts that file, and that file does the work. yarn.lock is converted once, and script/bootstrap installs with --immutable instead of stopping on yarn's major version. Node is the distribution's newest Node package: nodejs-current on Alpine and nodejs_latest on nix. Every Dockerfile stage that needs yarn also copies .yarnrc.yml and .yarn/releases/. The policies and both checklists say so, with the steps for converting and for a new repository. Model: opus-5-5

# script/bootstrap: install all dependencies needed to build and develop
|
|
# this repo. Idempotent: every install is guarded by a check so already
|
|
# installed tools are skipped. Base tools, node and yarn come from nix,
|
|
# apt, brew, or apk (detected in that order), with no version and no
|
|
# hash, because the distribution is trusted. It installs node, yarn and
|
|
# the node packages only when yarn.lock is in the tree. The
|
|
# distribution's yarn only starts the release file that yarnPath in
|
|
# .yarnrc.yml names, and that file does the work. So git pins the yarn
|
|
# that runs. Assumes nothing is present.
