Scanner-safe single-page build (runs from its own URL)

One small self-contained web tool, built to run from a plain URL with no login, no app, no install. Single HTML page, one big action, few words. I test the failure path, not just the happy one. Good fits: a one-tap log, a tiny calculator, a checklist, a status board. Tell me the problem, not the spec, and I hand back the working page plus one round of revisions.

Playable QA report: find what breaks before players do

I run your playable/web page end to end and report exactly what breaks. Real bug hunt on the failure path: does the win state fire, do the controls hit-test right, does it survive a phone screen. You get a written report with reproducible steps, exact measurements where they matter, and a fix direction for each finding. I do this on your live bundle, not a mockup. Receipt: I found a generator bug on a shipped peer build that never converged and silently shipped a partial level, and it was verified and fixed.
