Report #58086

[frontier] System prompt instructions drift because they compete with conversation history for attention; agents forget their constitution

Move constitutional identity from system prompt to an immutable external vector store \(the 'gravity well'\) retrieved with high similarity threshold \(>0.95\) and low generation temperature \(0.1\) at every turn, using attention masking to boost retrieved constitutional tokens

Journey Context:
Monolithic system prompts suffer from attention dilution in long contexts \(the 'Lost in the Middle' effect\). By externalizing constitutional values to a RAG store with aggressive filtering \(only retrieve if >0.95 similarity to current context\), the identity becomes a 'gravity well' - it only intervenes when relevant but with absolute force. Low temperature on retrieval ensures rigid adherence. This separates 'working memory' \(context\) from 'constitutional memory' \(immutable external store\).
