Niyra's memory, measured: 98.2% recall on LongMemEval

The memory system that serves every Niyra conversation now has a public, reproducible number behind it. On the complete LongMemEval benchmark (500 questions, 246,738 conversation turns), the production retrieval stack scored 98.2% recall@10 and 92.0% recall@5, measured at turn level with zero benchmark-specific tuning. Knowledge-update questions, the "this fact changed, do you know the current truth?" category, came in at 100%. The full write-up publishes the methodology, the control arm, and every caveat, including what these numbers do not mean.
