The harness forced software WebGL (--disable-gpu --use-gl=swiftshader) on every host. Measured here on an idle editor page over 20 s: that costs 373% of a core at 8 fps, while the Intel HD 630 via ANGLE/Vulkan costs 69% at 56 fps. The full suite now runs in ~124 s. Note the app is not rendering 60 fps as previously assumed - in software it only reaches 8, and a single frame costs more than any throttle interval would save, which is why capping the framerate had measured no effect. --use-angle=gl and --use-gl=egl look cheaper still but get no WebGL context at all, so the app never renders. They are not usable and are named in the comment as such. There is deliberately no software fallback: a host without a usable GPU should fail loudly rather than drag the machine to a standstill. None of the 267 checks reads the rendered image anyway - they read window.__gm.locate() and the debug hook, and the screenshots assert nothing - but Pixi needs WebGL2 to run at all. The browser launch moves out of harness.mjs into tools/lib/browser.mjs, which also supports GM_REMOTE=user@host via an SSH-forwarded CDP port. That path is unfinished: the tunnel degraded until the suite crawled at ~25 s per check, and forcing software WebGL on a desktop with a real card brought it to its knees. README says so plainly rather than advertising it. Also: the jump-run HUD check asserted a fixed "Coins 1/10", which fails on a faster host where the same walk sweeps up two coins. It now asserts the HUD against the count the run actually reached - the real guarantee is that HUD and state agree. Verified: npm run check green (404 tests), 267 e2e ALL PASSED and 24 jump-run checks ALL PASSED against the GPU flags. The fallback removal leaves the flag set on this host identical (same flags, different order), so it was not re-run. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
