SHORT ANSWER
Persistent identity requires more than saving chat logs. A portable pet needs a documented profile, memories with provenance, behavioral parameters, assets, relationship state, and rules for migration. Open formats could preserve continuity, but they also create privacy and authenticity challenges.
What makes identity
Name and appearance are only the surface. Habits, response patterns, important events, learned preferences, relationships, and the world state around the pet all contribute to continuity.
Portable data versus portable behavior
An export may preserve facts without reproducing the same personality on a different model. Migration tools need to state what is exact, translated, summarized, or lost.
Authenticity and consent
Signed exports and version records can help prove origin. Shared pets raise questions about who may copy, edit, delete, or transfer memories involving other people.
A practical first step
Vendors can publish schemas, support user-readable exports, preserve local fallbacks, and separate user-owned data from proprietary model weights. Interoperability can improve incrementally without claiming perfect immortality.
