From 461fb06a042b92718b645a6f06e3762bce06836c Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 5 Oct 2026 16:12:17 +0000 Subject: [PATCH 01/10] chore(release): remove the unused surface gate Nothing calls it since publish-all stopped running it; it was reachable only from its own test. Removes scripts/lib/surfaceGate.ts and its test.
