The design's original metric needs MSN resupply-date extraction and MSN resolution detection, neither of which exists yet — a future sprint, not a stated absence like tier accuracy.",

    "match_rate_precision is only ever published when gold_set_size is zero that month — every auto-match was character-for-character the dm+d name, so there was nothing for a person to grade. A month with a nonzero gold_set_size and no precision figure means real judgement calls occurred and were not labelled; that row stays that way permanently, the ledger is never restated."
