From 6dabc53e9f6ac1c7abdce4d3f08d6817d5a29cba Mon Sep 17 00:00:00 2001 From: "kiloconnect[bot]" <240665456+kiloconnect[bot]@users.noreply.github.com> Date: Thu, 19 Feb 2026 16:45:59 +0000 Subject: [PATCH 1/2] feat: replace hardcoded ENABLE_UNIVERSAL_VERCEL_ROUTING with dynamic Edge Config flag Replace the hardcoded boolean constant with a runtime-toggleable flag backed by Vercel Edge Config. This allows admins to flip the universal Vercel routing switch without redeploying. Changes: - Add @vercel/edge-config dependency - Create src/lib/edge-config.ts with TTL-cached reader (15s) and writer - Update src/lib/providers/vercel.ts to use async isUniversalVercelRoutingEnabled() -
