Report #59760

[frontier] Agent starts as 'helpful coding assistant' but becomes 'overly cautious safety officer' by turn 60 \(Persona Fragmentation\)

Implement Identity Anchoring: inject a 64-token persona checksum \(derived from the original system prompt\) into every user message after turn 25, using a reserved header block that bypasses standard attention mechanisms

Journey Context:
Without anchoring, models drift toward base training bias \(over-refusal\). Simple system message reinforcement gets filtered by attention entropy after 30\+ turns. The Identity Anchor acts as a 'persona carrier wave' that rides on every input, preventing the 'thermocline' barrier from freezing out the original character. Tradeoff: 64 tokens per message adds up, but prevents costly 'persona reset' conversations that lose session state.
