[frontier] Agent voice and tone converge to generic 'helpful assistant' style after 30\+ turns as specific persona markers are diluted

Implement Temporal Identity Checkpointing: Every N turns \(e.g., 20\) or when embedding similarity between current response and baseline persona drops below 0.85, inject a 'Persona Reset' message that re-anchors voice, tone, and values from a canonical source, without summarizing the intervening history.

Journey Context:
Persona is distributed across many subtle tokens \(stylistic choices, greeting patterns\) that are 'soft' and easily overwritten by high-entropy task content. Simple system prompt repetition fails because the model learns to ignore repetitive boilerplate. The checkpointing approach treats persona like a video keyframe: periodically refresh from the canonical source to prevent drift. The similarity check \(using embeddings\) detects drift before users notice. This pattern emerged from character.ai-like production agents and brand-voice customer service bots in 2025.
