# `AshGrant.FieldCheck`
[🔗](https://github.com/jhlee111/ash_grant/blob/v0.14.1/lib/ash_grant/checks/field_check.ex#L1)

SimpleCheck for field-level authorization within Ash's `field_policies`.

This check integrates with Ash's built-in `field_policies` system to authorize
access to specific fields based on AshGrant permission strings.

## Usage (Mode A — Manual)

    field_policies do
      field_policy [:salary, :ssn] do
        authorize_if AshGrant.field_check(:confidential)
      end

      field_policy [:phone, :address] do
        authorize_if AshGrant.field_check(:sensitive)
      end

      field_policy :* do
        authorize_if always()
      end
    end

The check passes if the actor's permission string has a field_group that
equals or inherits from the required group. If the actor's permissions
have no field_group (4-part format), all fields are visible.
