    "description": "The top-customer ARR concentration reported in the PRIOR period — the comparison anchor for the current `customers.top_customer_concentration`. The board reads the two together to render the concentration trend on the bespoke customers card (rising concentration = growing single-account dependency risk). Common pitfall: comparing a top-1 concentration to a top-5 concentration across periods — keep the \"top-N\" cut identical.",
