QualiBact qualibact-v1.1 thresholds for Campylobacter jejuni, derived from a curated 654-genome ATB subset re-run with qualibact-engine for v1.1.
Compared with v1.0, the curated re-run pulls several bounds inward:
Assembly-size upper bound pinned at 2.1 Mb on advice from the Campylobacter jejuni subgroup (INSA Lisboa Campylobacter subgroup). The engine emitted 2.0 Mb for the curated run, but expert review of a diverse isolate set (human + food + animal + environmental) showed that 2.0 Mb was excluding a small number of well-supported, high-quality genomes; 2.1 Mb retains them.
See the methods page for qualibact-v1.1 for details on how thresholds are derived overall.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
