qtDiagnosing Qt Cross-Thread Signal/Slot Delivery Failures
A diagnostic guide for Qt signals that leave a worker thread but whose slots never run, run late, or run on the wrong thread — with ordered checks and fixes tied to each finding.
QObject cross-thread timer failure: queued versus direct signal delivery under concurrent workers

Cross-thread signals follow a related rule: with Qt::AutoConnection , delivery becomes queued, so the slot runs later in the receiver thread's
