Report #94764

[frontier] Agent persona gradually reverts to base model behavior as high-entropy user queries drown out the persona embedding in attention mechanisms over 20\+ turns

Use Latent Space Re-Anchoring: create a unique high-salience 3-token signature \(e.g., <\|PERSONA:ARCH\|>\) associated with the full persona via few-shot examples in the system prompt; inject this signature every 5 turns to trigger the persona embedding without textual bloat

Journey Context:
Re-injecting full persona descriptions fails because attention heads weight recent novel tokens higher than repetitive system text. Summarizing the persona loses nuance. The checksum acts as a 'macro' or 'symbol' that expands in the model's latent space to the full persona vector. This exploits the model's ability to associate specific rare tokens with complex concepts \(similar to code names\). The risk is collision with user input, so the token must be truly unique \(use GUID fragments or reserved Unicode\).
