bun install, as the account, in the checkout.
Two things stated because a failure here is otherwise opaque.
The lockfile is frozen — bunfig.toml sets [install] frozenLockfile = true — so
bun resolves from bun.lock and nothing else. A package.json that disagrees with
it is a hard failure rather than a quiet resolution, which is deliberate: the
friction exists so an unexplained lockfile change shows up in a diff. If the
install fails complaining about the lockfile, the section says that is the
frozen lockfile working and that it wants a human to read the diff, rather than
reporting a generic failure.
node-pty has no Linux prebuild, so this compiles it from source on every machine.
That is what build-essential and python3 are in machine-setup's core utils for,
and the section says so — the failure would otherwise surface much later as a
terminal that never starts.
Success is checked by the artefact rather than by the exit status: bun can
complete while the native module is not built, because it skips a dependency's
lifecycle scripts unless it trusts the package. So the section looks for
node_modules/node-pty/build/Release/*.node and, when it is missing, names the
consequence and the command that fixes it instead of reporting success.
