No sidecar code change. This version exists to ship hyper-deploy 0.4.11, which stops DeployServer pinning every connection it ever served: OverlayProtocol's _paired set was pruned only by detach(), and nothing called detach(), so each inbound mux -- and the stream behind it -- was retained for the life of the process. The sidecar is where that bill came due. Its bare process was OOM-killed on tabertron 2026-09-02 at 10:04:22 with anon-rss ~22 GB after 3817s, taking the tmux scope (and pear-git-v3 with it) down. A restart reproduced the growth immediately: 304 MB at 4m29s -> 4719 MB at 18m38s, ~315 MB/min. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
