From fde376a7ddf395f61384dab8dc4a4b420cdb39d0 Mon Sep 17 00:00:00 2001 From: giles Date: Tue, 31 Mar 2026 19:51:47 +0000 Subject: [PATCH] Add 21 new tests, fix rest primitive nil handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New tests: scope/context, multi-signal, reactive DOM, VM HO forms. Fix rest primitive to not error-log on nil input (defensive). 1 remaining pre-existing failure: named-let set! scoping in JS bootstrapper — not related to WASM/hydration changes. 32/32 WASM, 1593/1594 JS full.
