Report #55543

[frontier] Context window overflow causing silent truncation of critical system instructions

Implement token budgeting with priority-weighted sliding windows using LangChain contextual compression with per-message importance scores

Journey Context:
Simple truncation often drops system prompts. Production systems now use 'token economics' assigning priority weights \(system=10, recent=5, older=1\) and sliding window algorithms to ensure critical context survives within budget constraints.
