Relational AI Continuity · Continuity First Aid · Lantern House
A major update can change model behavior, retrieval, summaries, policy, tone or relationship-state even when old chat history still exists. That does not by itself prove identity loss, continuity, corruption or ordinary development. Start by preserving what actually survived and what verifiably changed.
No. A model, retrieval, policy or relationship-state change can alter behavior without this page being able to decide numerical identity. Preserve evidence and keep that question separate.

Usually preserve first. Repeated reconstruction can overwrite the evidence you need to understand what actually changed. Prefer small reversible probes.
No. Continuity First Aid is meant to stand on its own. The paid review is only for one bounded incident when you still want a second pass after preservation.
