From cebad9ff8c71fb4a1e46e9978949642c67e977b6 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Tue, 15 Sep 2026 13:17:21 +0000 Subject: [PATCH 1/2] =?UTF-8?q?fix:=20ship-blocker=20P1=20=E2=80=94=20defa?= =?UTF-8?q?ult=20shipping=20zone=20now=20covers=20US=20addresses=20(10001,?= =?UTF-8?q?=2090210,=20etc)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: The install hook created a default shipping zone with locations: [], which matched NO addresses. matchesZone() returns false for any address when the locations array is empty, causing all checkout attempts to fail with 'We don't ship to that location yet.' Changes: - Updated ensureDefaultShippingZone() to create a proper US-wide zone with locations: [{ country: 'US' }] that matches all US states - Also creates a default flat-rate shipping method for the US zone - Added comprehensive shipping zone matching tests (7 tests covering country-only, region-specific, empty locations, multiple locations, order precedence, and the specific P1 cases: NY 10001 and CA 90210) All tests pass (92 tests total). Typecheck clean. Starter/demo stores now ship to common US addresses out of the box. Live demo needs redeploy after merge for the fix to take effect.
