# Evidence, exploration and items needing review

Checked against the product’s code on 7 November 2026.

Under **Optimization** > **Personalization**, the tabs **What it has learned**, **What it is trying** and **What needs a person** show recorded evidence and policy. They do not establish that an automatic cycle of testing and applying changes is running on your site.

## Read the recorded evidence

1.  Open **What it has learned**.
2.  Inspect a reading for the intended [slot](https://docs.amadalis.ai/reference/glossary/#slot) and piece of content.
3.  Read its evidence and context.
4.  Check how much the configuration is willing to trust that reading.

When there is too little evidence for one set of circumstances, a reading from a broader group can be used.

The default trust setting is zero. A screen containing a lift reading therefore does not by itself mean that reading is changing delivered scores. Review the active settings and connection with Amadalis before depending on that effect.

## Review rules for trying alternatives

[Exploration](https://docs.amadalis.ai/reference/glossary/#exploration) defaults off.

1.  Open **What it is trying**.
2.  Review the rules for trying alternatives.
3.  Review the share of traffic they use.
4.  Review what they may draw from, for how long and within which bounds.

An [envelope](https://docs.amadalis.ai/reference/glossary/#envelope) is a saved set of limits for possible changes. **Record this envelope** is a deliberate action with its own consequence and reason. Recording it is not evidence that a cycle of automatic changes has started or that any page was published.

## Keep a person’s decisions visible

**What needs a person** counts what is waiting on a human: visitor erasures not yet carried through, campaigns a person is holding, slots set up but never served, and saves the platform refused.

1.  Open **What needs a person**.
2.  Open the count for the list you want to inspect.

A held targeted item is resumed on **Targeted content** under **Personalization**. To decide a proposal to change the engine’s settings:

1.  Open **What it is trying**.
2.  Choose **Apply it** or **Reject it** for that proposal.
3.  Read its approval card.
4.  Approve only the intended decision.
5.  Check the exact result and current state afterwards.

Continue with [slot and measurement settings](https://docs.amadalis.ai/optimization/slots-and-measurement/) for delivered ranking rules, or [affinity settings](https://docs.amadalis.ai/optimization/affinity-settings/) for the decaying scores of visitor actions.
