2204| `reason` | The denial reason: the fixed text `Blocked by classifier` in most sessions, or the classifier's written explanation when the session's classifier model provides one. For a denial where a safety check separate from auto mode refused the classifier's request or its response didn't parse, the reason starts with `Auto mode could not evaluate this action and is blocking it for safety`. For a denial because the classifier model was unavailable, the reason is the fixed text `Classifier unavailable`. See [Review denials](/docs/en/auto-mode-config#review-denials) |

2204| `reason` | The denial reason. For a classifier verdict, in most sessions it names the matched rule in square brackets, such as `[Data Exfiltration]`; see [Review denials](/docs/en/auto-mode-config#review-denials) for the other forms. For a [no-verdict denial](#permissiondenied-decision-control), it starts with `Auto mode could not evaluate this action and is blocking it for safety`. For a denial because the classifier model was unavailable, it is the fixed text `Classifier unavailable` |
