From 68d24a7496cbe0b7ede6c867c1e1ecb353f5c95f Mon Sep 17 00:00:00 2001 From: Matt Jones <47545907+SoundMatt@users.noreply.github.com> Date: Tue, 16 Jun 2026 16:00:03 -0700 Subject: [PATCH 1/5] fix: MSVC C4244 narrowing in sim.hpp; replace missing DCO action MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit sim.hpp: use std::chrono::milliseconds::rep as uniform_int_distribution template argument instead of `long` — on MSVC milliseconds::rep is long long, causing C4244 when passed to a long distribution. dco.yml: dco-check/dco-check@v1.1.0 does not exist on the Actions marketplace; replace with an inline shell check that iterates all PR commits and requires a Signed-off-by: line in each message body.
