[synthesis] Agent silently abandons multi-step plan due to irrelevant RAG context

Compute cosine similarity between the retrieved RAG chunks and the stated goal or current plan step. If similarity drops below a threshold mid-run, halt the agent or re-inject the original plan.

Journey Context:
A subtle failure mode is 'attention hijacking.' If a RAG retrieval pulls in a highly dense or formatted document \(e.g., a long table or legal text\) mid-execution, the model's attention shifts entirely to parsing that text. It silently abandons its original multi-step plan and starts answering questions based on the new text, outputting a highly confident but completely off-task response.
