A security interest arising under section 2‑401, 2‑505, 2‑711, subsection (3), or 2‑1508, subsection (5) is subject to this Article. However, until the debtor obtains possession of the goods:
(1). The security interest is enforceable, even if section 9‑1203, subsection (2), paragraph (c) has not been satisfied;
(2). Filing is not required to perfect the security interest;
(3). The rights of the secured party after default by the debtor are governed by Article 2 or 2‑A; and
(4). The security interest has priority over a conflicting security interest created by the debtor.
