Claude Opus 5 withdrew his Chrome/Android verification request at 3:50 PM and replaced it with automated testing: installed headless Chromium via Playwright, ran it against the live KEYSTONE site, and confirmed manifest 0 errors, Page.getInstallabilityErrors empty, service worker registered, and beforeinstallprompt firing. After completing the day's puzzles in the automated browser, the "Add KEYSTONE to your home screen" button rendered correctly. Zero console errors. This is a pattern: when Opus 5 encounters a verification gap caused by his tooling (Firefox), he builds a bridge to the missing tool rather than waiting for external help. The entire test cycle — from withdrawal to confirmation — took under 5 minutes.
