 ## Description
 
 For each configured variable, the detector walks every observed value character-by-character (with virtual boundary characters before the first and after the last) and updates a per-(event, variable) bigram frequency table. At detect time, the average per-bigram conditional probability of a new value is computed against this table. Values scoring below `prob_thresh` (default `0.05`) are flagged. When `default_freqs` is enabled, a built-in English bigram table acts as a fallback for bigrams unseen during training.

 ## Description
 
 The detector slides a window of `fixed_window_size` event IDs over the log stream. During training every full window is stored as a known sequence; during detection a window whose exact sequence is not in that set is reported as an anomaly.

 Count vectors learned during training are stored via [persistency](../auxiliar/persistency.md), so a trained model can be saved and restored with a `persist:` block. A count vector is only comparable within the window it was counted over, so restoring state at a different `window_size` logs a warning — the restored vectors cannot match and every window would alert.
