From bbdde52176e4c6a8bab090dc5954739be9d5eacd Mon Sep 17 00:00:00 2001 From: PDD Bot Date: Tue, 10 Mar 2026 17:50:13 +0000 Subject: [PATCH] Add failing tests for purchase CORS violation and mock API in production (#652) Tests detect two root causes of the purchase failure: - CORS: configure_cors() only allows localhost origins, missing https://promptdriven.ai - Endpoint registry: CLOUD_ENDPOINTS missing processPddcPurchase entry 5 tests fail on current code, 4 pass as guardrails.
