+/**
+ * v1.4.16 phase B5d — full-flow integration.
+ *
+ * MockAIProvider returns a payload where the model claims a high
+ * `confidence: 99`. The wrapper MUST overwrite that with the
+ * deterministic `computeConfidence()` value, which (with the default
+ * resolver: n=9, recencyDays=0, ratio=null) yields:
+ *
+ *   nScore   = 10 + 10*log10(9) ≈ 19.54
+ *   recency  = 30 (recencyDays=0)
+ *   signal   = 15 (null)
+ *   total    ≈ 64.54 → 65
+ *
+ * After generation, we mount InsightAdvisorCard with the parsed payload
+ * and assert the rendered ConfidenceMeter band corresponds to the
+ * server-computed value (medium/yellow), NOT the model's claimed 99
+ * (which would have rendered the green high band).
