Two recurring console errors, each masking real ones.
"Identifier 'BackupAppCard' has already been declared": the app has two
script loaders that could not see each other's work. The boot-time
system loader injects tags with NO id and dedupes by script[src]; the
SPA's loadScript injects with an id and deduped ONLY by that id. So a
file both of them load — backup-app-card.js is on the boot list AND in
the overview Backups tab's asset chain — loaded twice whenever the SPA
loaded second: its getElementById check cannot see an id-less tag. The
class redeclared with an uncaught SyntaxError. The blindness was
one-directional, which is why it looked sporadic. spaClean.loadScript
now also matches by src, closing the asymmetry for every shared file,
not just this one.
"ConfigSidebar: config-categories-list element not found", three to
four times per navigation: renderConfig populated the admin sidebar
unconditionally, but the backup center's Configuration tab EMBEDS that
renderer inside its own pane (renderConfig('backup', <target>)), where
the sidebar element legitimately does not exist — and the refresh
coordinator re-renders that tab on every task event. Populating is now
skipped when a target is passed: an embedded render does not own the
admin shell. The error stays for target-less renders, where a missing
sidebar genuinely is a broken shell.
Verified in a live session: repeated sweeps across /tasks, the overview
Backups tab (Configuration sub-tab included) and a per-app Backups page
produce zero new occurrences of either error — confirmed against a
live console buffer via a sentinel, since the buffer retains the
pre-fix history and re-reading it can look like recurrence.
