[frontier] Context window truncation causes agents to forget critical constraints, system prompts, or conversation history leading to infinite loops

Implement Context Bankruptcy: when token count exceeds 70% of context window, archive the full conversation to vector store with a bankruptcy declaration timestamp, reset the context with a compressed summary, and maintain a pointer to the archived session.

Journey Context:
Naive approach: truncate oldest messages. Fails when system prompts or few-shot examples get pushed out. Better: summarize and truncate. Still loses nuance \(e.g., user said 'don't use Python' 20 turns ago\). Production failures show agents looping when they forget constraints. Frontier pattern is explicit 'bankruptcy'—like Chapter 11 for context. The agent announces 'Declaring context bankruptcy at turn 45, archiving to session\_abc\_45, resuming with summary: \[constraint list\].' This enables audit trails and exact recovery. Alternative: sliding window—inefficient token usage. Bankruptcy is cleaner and debuggable.
