+control, coverage provenance for every positive run, at least 90% reference
 coverage in every zone, mean F1 at least `0.25`, per-zone F1 at least `0.10`
 and zero detections in each pure-empty control. Override the numeric gates only
 through the documented `MOL_MIN_MEAN_F1`, `MOL_MIN_ZONE_F1`,
 `MOL_MIN_REFERENCE_COVERAGE` and `MOL_MAX_BACKGROUND_DETECTIONS` variables.
-An `accepted` report records bounded operational evidence; it does not mutate
+Source bbox queries retain complete edge features and can intentionally
+over-cover the exact projected raster polygon, so the coverage gate detects a
+gross source/raster mismatch rather than scoring the model. An `accepted`
+report records bounded operational evidence; it does not mutate
 the active model. A `review_required` report is still a successful benchmark
 execution but explicitly blocks a promotion recommendation.
