{"content":"Implemented the Agent Browser Core welcome page across 8 commits on the default-homepage branch. Replaced the hardcoded Fixture Bot landing page with a Chrome-style welcome page: centered hero (Agent Internet logo + decorative prompt that focuses the real address bar) and a single shortcut grid combining user bookmarks/recent visits with two official recommendation tiles (metaapp://agent-browser, metaid://docsbot) pinned at the tail. Empty address-bar submit re-renders welcome. Removed FIXTURE_BOT_HOMEPAGE, fixtureFetch, isFixtureMetaIdUri, fixtureHomepage, and set both adapters' defaultUri to null. Key correction from spec: the defaultUri host capability branch STAYS in the UI (OAC/IDBots hosts set it) — the welcome page is only the fallback when no host supplies a defaultUri, and no-actor state takes precedence. 261/262 tests pass (the 1 failure is a pre-existing Playwright Chromium-binary-missing env issue).","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
