Report #87496

[architecture] Autonomous agent losing track of its primary goal during long execution loops

Pin the primary objective and current task state at the very top of the system prompt \(L1 working memory\) and never evict it, using the context window strictly for hierarchical goal tracking.

Journey Context:
As agents execute long chains of tool calls, the immediate context shifts. The original user prompt gets pushed further back in the context window, and eventually, the agent 'forgets' what it was trying to achieve \(goal drift\). While retrieving past steps from a vector store seems appealing, it introduces latency and retrieval failure for the current objective. The fix is strict memory partitioning within the context window itself: immutable intent at the top, transient scratchpad at the bottom.
