• 呼叫: import fullseye as fs; fs.ledger.anomaly_operating_point(scores, labels, recall=0.95, confidence=0.95)(要直接呼叫實作,import anomeval; anomeval.anomaly_operating_point(scores, labels, recall=0.95, confidence=0.95);從台帳取用則 opsspc.get("anomaly_operating_point"))
選出能以 confidence 的信賴水準保證缺陷召回率不低於 recall 的最高閾值(table)。

scores (1-D, higher = more anomalous) and labels (1 / True = defective) are image scores of a held-out set that was NOT used to fit the detector. Detecting k of the n defective images, the exact one-sided Clopper–Pearson lower limit of the recall at level confidence is computed; the smallest k whose limit reaches recall fixes the threshold at the k-th highest defect score (>= rule: the highest threshold that still carries the guarantee, so the fewest false alarms). The guarantee holds for defects drawn like the held-out ones; it is a statement about a sample, not about every future defect. Returns threshold, recall_observed, recall_lower (the limit), detected, n_pos, n_neg, fpr (fraction of good images at or above the threshold), fpr_upper (its one-sided Clopper–Pearson upper limit at the same level) and n_required (the smallest number of defective images for which the guarantee is attainable at all:
ceil(ln(1 - confidence) / ln(recall))).
Raises ValueError when the guarantee is unattainable with so few defective images (n_pos < n_required): it never returns a threshold it cannot back. Also on empty / mismatched / non-finite input, non-binary labels, no good or no defective image, or recall / confidence outside (0, 1).
