Constant AI_MAGIKA_CONFIDENCE_THRESHOLD 

pub const AI_MAGIKA_CONFIDENCE_THRESHOLD: f32 = 0.50;

Default Magika ML confidence threshold for the confidence gate in MagikaRouter::classify_file() and media_meta::extract_metadata(). At or above this score, Magika’s classification is trusted directly. Below this score, the gate checks whether the file extension is in MAGIKA_KNOWN_EXTENSIONS: if yes, trust Magika; if no, fall back to extension-based ContentRouter. Configurable via [ai.enrichment] magika_confidence_threshold in foxingd config. CLI fxcp enrich uses this constant as the default.
