BackupEngine — manifest loading never poisons NASManifestCache:
Before: if the NAS manifest download failed for any reason,
BackupManifest() (0 entries) was written to NASManifestCache.
Every subsequent fast-path reconcile read the poisoned cache and
set nasArchiveTotal = 0, making every asset appear as needing backup.
Checkpoint writes then set the cache to 1 entry (first upload), which
is why NAS Archive flipped from 7422 to 1 when starting a backup.
After: NAS > cache > empty. If NAS download fails or returns an empty
manifest, the existing cache is used as the authoritative base and is
never overwritten. Only a non-empty NAS manifest replaces the cache.
BackupView — live counters stay on persistent totals:
- nasArchiveDisplayCount: snapshot.nasArchiveTotal + uploadedFiles during
active backup so the NAS Archive card grows as uploads are confirmed
instead of jumping to the session count
- alreadySafeDisplayCount: adds both uploadedFiles AND skippedFiles —
skipped means the file was already on NAS (fileExists=true) but not
yet in the manifest, so it is safe and should be counted immediately
- notBackedUpDisplayCount already derived from alreadySafeDisplayCount
so it correctly shrinks as uploads and skips are confirmed
