bun 1.4.0 was published 2026-08-20 and https://bun.sh/install serves
whatever is newest, so machine-setup provisioning a box today would put a
two-day-old release under the platform and every pm2 app except
officer-pty. The owner asked for a temporary hold on 1.3.
The SERIES is pinned, not a patch — BUN_SERIES=1.3, resolved to the newest
1.3.x at install time so bug fixes inside the series still land, and no
1.3.14 to rot into "the version we happened to pick" the way setup_22.x
did for Node. The version reaches the installer as its documented first
positional argument (a release tag), and install_bun refuses to run with
an empty one: taking whatever bun.sh serves is the single outcome the pin
exists to prevent, so no bun at all is the better failure. Loud, and
officer-setup's pre-flight already stops on a missing bun.
Resolved from the npm registry rather than GitHub's releases API, which
is the obvious source and the wrong one — 60 unauthenticated requests an
hour per IP, and it returned 504 twice while this was written. An empty
answer installs nothing, so where it comes from is load-bearing.
The section now reads four states instead of two. "Installed" was one
answer covering a machine inside the pin, one behind it, and one past it;
past it is the case worth catching, since that is what bun upgrade leaves
and nothing else reports it. Above and below get different prose and both
offer to move; nothing is corrected silently.
What a setup script cannot cover: bun upgrade takes no version argument —
latest stable or --canary, verified against its own --help — so it always
jumps past the pin without saying so. Hence the doctor check, which reads
engines.bun rather than repeating the number, because a second hardcoded
copy is a second thing to drift. bun ignores engines (verified: an install
declaring 1.9.x ran clean under 1.3.14), so the field is the declaration
and doctor is the enforcement. Confirmed bun install --dry-run still
resolves frozen with the field present and bun.lock unchanged.
This host is already on 1.3.14 and inside the pin, so nothing moved here.
Also fixes three more stale process counts in the same block.
