    "answer": "WC2 makes 0.9 the current modeled A value for T/P; B remains 0.7 under WC1. WC3 is a limited observation for A after P, not a replacement model or a whole-tile validation for the earlier period. It supplies no B observation. Report modeled and observed values with their technology, period and scope rather than calling either tile's real coverage verified.",
