Hallucination Summary
Filter: skipped. Hallucination pass skipped (no anti-GT). Penalty pinned to 1.0 so the composite formula and weights stay identical to the active mode and scores remain comparable across runs.
Filtered Hallucinations
Filter inactive — no suggestions were inspected for anti-GT hallucinations.
