Send a video. Get a fix. Gecko catches the bug in a screen recording and opens a pull request that proves it and fixes it. Gecko watches a plain screen recording of a web-app bug (no browser extension, no SDK, no logs), works out exactly what the user did, replays it in a real browser, and writes a Playwright test that fails the same way the video shows. Then Muse Code fixes the bug with that failing test as its spec, and Gecko only accepts the fix once the test passes and the rest of the suite stays green. Every claim Gecko makes is checked by running code. When it cannot reproduce a bug, it says so, with its evidence, instead of guessing.
