From a7383510fb05abc98b992240cb76ad4b6c598956 Mon Sep 17 00:00:00 2001 From: Ophestra Date: Sun, 4 Oct 2026 01:05:10 +0900 Subject: test/sandbox: migrate tests This significantly improves performance, removing overhead of nix, python, and virtualisation. Running this in an unprivileged container required patching the kernel, but since special runner setup was already needed, that was an acceptable tradeoff.
