The Modules screen as built (website#143), and the three things standing it
up against a live server exposed. Two of them are older than this phase and
neither was reachable from a test.
- A fresh install over a row the previous boot left `startup_failed` rendered
the old failure - "module directory not present on the volume", one second
after the files were written there - and, because that branch is not
pending, suppressed the restart banner the install had just told the
operator to use. Fixed by a derivation rather than a special case: the
loader scans once at require time, so a module on the volume with no live
record arrived after that scan and anything the row says predates it.
- The boot refresh had been nulling every install's provenance. source and
sha256 exist for this screen and never survived a restart, because
lifecycle.boot() re-records with neither and the upsert assigned both
unconditionally. It could not have been found before Phase 4 wrote the first
non-null value those columns ever had - and the model's test fake
reproduced the defect faithfully, assigning exactly like the SQL.
- The restart killed the server outright on Windows. process.kill(pid,
'SIGTERM') reaches the graceful handler on Linux and is unconditional
termination where POSIX signals do not exist, so a Windows host got no
module onShutdown, no pool close and no log flush. process.emit('SIGTERM')
reaches the same listener everywhere. The test had stubbed process.kill and
asserted the call - precisely the call whose meaning differs by platform.
That last one generalises: deployment is Linux containers and would never
have shown it. A smoke that only runs where the code ships cannot find a class
of defect that only bites the people developing it.
