Hi, some greenpass have a special tag in the signing certificate ['extensions']['extendedKeyUsage'] with values:

    public const OID_RECOVERY = "1.3.6.1.4.1.1847.2021.1.3";
    public const OID_ALT_RECOVERY = "1.3.6.1.4.1.0.1847.2021.1.3";

Those certificates (issued after a recovery post vaccine) are valid like the 3rd dose. You can see the validation in android-sdk source code here
