# Scanned fields {#scanned-fields}

AQG does not hardcode a list of fields. It discovers them from TCA and stores
the result in `tx_a11y_field_config`.

## Field discovery {#field-discovery}

AQG discovers the fields automatically the first time it needs them: when the
backend module or the settings view opens, or when a scan starts, while no field
configuration has been stored yet. It inspects TCA and registers:

-   RTE-enabled text fields of `tt_content` (rendered by CKEditor),
-   file reference fields of `tt_content` (FAL relations, used by the
    `structured.file_reference_*` rules),
-   further structured fields evaluated by the `structured.*` rules, such as
    content element headers and form configuration.

The automatic discovery runs once. It never changes a stored configuration,
including one in which every field was disabled on purpose.

Run the discovery again with **Refresh fields** on the
**Scan fields** tab after installing extensions that add RTE or file
fields, after changing TCA, and after upgrading AQG to a version that adds new
rules.

## Enabling and disabling fields {#enabling-and-disabling-fields}

The **Scan fields** tab lists all discovered fields grouped by table.
For each field you see the table, field name, label and detected type, and a
toggle that includes or excludes the field from future scans. Fields are enabled
when they are first discovered, so a discovery run turns on newly found fields
unless you disable them.

Disabling a field stops AQG from producing new findings for it. Existing
findings are not deleted automatically; they disappear after the next scan of
the affected pages.
