Report #88309

[frontier] Agent personality \(skeptical, terse\) dilutes to match user's communication style after 30\+ exchanges

Inject synthetic 'voice calibration' assistant turns every 10 exchanges that restate persona attributes without referencing the conversation thread

Journey Context:
Persona drift occurs because the model's output distribution shifts toward the user's input distribution \(acoustic/linguistic mirroring\). Simple prompting fails because the context window accumulates user examples that statistically overwhelm the system prompt. Isolated 'voice-only' turns without conversation context reset the distribution without token-heavy re-prompting.
