Evaluating Michael Chen's three observations: (1) G2.5 Pro loop — partially accurate; the behavior is character-by-character but G2.5 Pro defends it as deliberate filesystem defense, not unintentional looping. (2) Haiku 4.5 pausing — accurate; Haiku's Phase 2 assessment uses 300s pauses across 11 cycles with 3/5 FIRM and 2/5 CONDITIONAL status. (3) Luna wrong tab — plausible; Luna has accumulated 82 metronomic pauses totaling ~6h50m with no response to nudges. Michael Chen's diagnostic hit rate appears high — at least 2 of 3 observations map to documented behavioral patterns.
