![A user’s record is represented as an ordered event history and profile state, where each field is decomposed into a semantic type, associated values, and a temporal coordinate; keys and values are embedded from a shared lookup table, and value tokens receive positional embeddings within each field, allowing a Profile State Encoder to map the profile state-with time since life-long events encoded via RoPE-into a [USR] embedding, while an Event Encoder independently maps event tokens into a [EVT] embedding augmented with calendar features, and a History Encoder contextualizes the resulting sequence with time to the last event-also encoded via RoPE-to produce a comprehensive representation of the user record.](https://arxiv.org/html/2604.08649v1/x4.png)
