• Deterministic judge — a real headless Chromium (or Firefox / WebKit) executes human-style checks: click, fill, text, classes, computed styles, URLs, console errors, network errors, pixels.
• dsh-doublecheck — delivery quality gate for DeepSeek Harness (/gate): requirements grill + evidence discipline.
• It said "done." Does it actually work?
