What's new
Unknown Reduction. After every full scan, Ciela now runs a retroactive re-classification pass — all messages in the database are re-scored against the current rules. Senders that were previously stuck in Unknown because the classifier didn't recognise them yet will automatically move to the right category on the next scan, without requiring a full re-scan from scratch.
2-column inbox layout restored. Selecting a sender replaces the sender list with the detail view. Back button returns to the list.
Classifier: \�alidation code\ added to SECURITY_KEYWORDS.
TD sweep: Rust safety (naked .unwrap()\ removed, dead code suppressor removed, \let mut\ in tests fixed). Frontend type guards (\�sJobStatus\ eliminating 3× as-any casts), clean-error toast in SenderPane, Collapse atom extracted to \�toms.tsx, \DashboardView.tsx\ deleted. InboxView tests updated for 2-column layout.
