PM2 runs update-check.mjs as a cron *restart*, and PM2 7 stops a process
that is still running at the next minute boundary. Any update that needed
npm install or next build (more than ~55s) was killed half-way: the lock
was left behind, HEAD had already moved at the pull so the next run saw
nothing to do, and next build had already wiped .next under the live
server — a box that broke after a weekend push and stayed broken.
- The cron run is now a quick CHECK: fetch, decide, and hand the work to a
detached worker (--apply) that PM2's next tick can't reach.
- "Up to date" is judged against scripts/.built-commit (what .next was built
from), not HEAD, so a pull that was never built finishes on the next check.
First run on a machine adopts a complete build that is newer than HEAD's
last move and rebuilds anything else — that rescues boxes the old updater
already stranded.
- The previous build is set aside as .next-prev and restored if the build
fails, so a broken push never leaves a box without a build; failures retry
after 15 min, then hourly (scripts/.update-failed).
- The lock holds a pid and is atomic; build dirs are deleted without ever
following the links in .next/node_modules into the real node_modules.
- Every instance in scripts/instances.json is restarted, and python/pip
children stay hidden on Windows now that the worker has no console.

Instances were started by hand and updated by hand, so they drifted behind
master silently. Now: PM2 supervises the dashboard and the clicker, a logon
task brings them up, and a 5-minute task pulls, rebuilds and restarts when
master moves.
Restarting on every push is only safe because the scheduler now survives it.
It was pure in-memory state (_global.__autoTrader), so any restart silently
stopped automated trading with the dashboard simply showing it as off. It now
mirrors running/action/symbol/stopAfterAll to the settings table, and
resumeSchedulerIfPersisted() picks it back up from the getClients() bootstrap.
No sync-wait was needed there: tick() already skips while a client reports
!syncComplete and while any account holds a position.
A failed build is never deployed — the build runs before anything restarts, so
a broken push leaves the previous build serving.
start-all and update-check both warm the app with a request afterwards. That is
load-bearing: getClients() is lazily bootstrapped, so until something makes an
HTTP request the Tradovate clients, the reporter and the resumed schedule never
start. That was already true of manual restarts.
Logic lives in Node so a macOS or Linux port only needs an equivalent of
install-autostart.ps1. Python deps are hash-guarded, so the common path is one
hash and one import with no network, and failure is non-fatal since only the
clicker needs them.
