| Where | What |
|---|---|
| Cart and order attributes | `_da_class`, `_da_score` (`"0"`–`"100"`), `_da_agent`, `_da_sid`. Written when a cart exists and consent is given. |
| Order tags | `doubleagent:bot` or `doubleagent:agent`, plus `doubleagent:agent:<family>`. Humans get no tag. |
| Customer events | `da_classified`, `da_final` |

Filter Orders by tag `doubleagent:bot` and save the view.
