Report #39572

[frontier] Critical tool schemas evicted from context window by conversation history

Implement three-tier memory \(working/recall/archival\) with importance-weighted promotion and explicit forgetting policies

Journey Context:
Simple truncation loses system instructions; FIFO loses recent but important facts. The MemGPT pattern organizes memory into tiers: main context \(working\), recall storage \(searchable\), and archival storage \(compacted\). Production implementations add 'importance scores' computed by a small classifier to determine what gets promoted to working memory vs. archived, preventing critical tool schemas from being evicted while allowing conversational fluff to be forgotten.
