[architecture] Important details get buried in the middle of a long prompt

Structure prompts with clear section boundaries and place critical instructions at the start or end; test with needle-in-haystack benchmarks.

Journey Context:
LLMs suffer from 'lost in the middle': information in the middle of long contexts is less likely to be used than information at the beginning or end. For memory-heavy agents, this means retrieval order matters. Don't just dump retrieved chunks in arbitrary order; rank by relevance and recency, and place the most critical items near the start or end of context. Benchmark with needle-in-haystack tests using your actual documents to find your model's failure zones. This is especially important when retrieved memories conflict—old vs new—and the model needs to prefer recent ones.
