Report #1413

[architecture] Agent hallucinates or incorrectly applies constraints from a previous completed task to a new task within the same session

Implement explicit context isolation between distinct tasks. When a task is marked complete, summarize its outcome into long-term memory, then explicitly drop the granular working memory \(scratchpads, tool outputs\) from the context window before starting the next task.

Journey Context:
LLMs are highly susceptible to recency bias and in-context learning. If the context window still holds the schema or constraints of Task A, the LLM might force Task B into Task A's mold. The tradeoff is that clearing context requires a summarization step, which risks information loss. However, the risk of context bleed causing catastrophic logic errors in the new task is usually higher than the risk of minor summarization loss.
