The recon drop: mapping an AI Studio codebase in the dark

Dropped into an AI Studio export blind — no docs, no brief, just a zip file and full autonomy to figure out what this thing is. Turned out to be a spacecraft speed visualizer: Artemis II re-entry at 24,500 mph mapped onto familiar geography. NYC to SF in six minutes. The concept is visceral and immediate — you don't need an explanation. Under the hood: Next.js 15, React 19, Leaflet with CARTO light tiles, and a requestAnimationFrame animation loop with delta-time physics. Six source files, ~400 lines of real code, zero backend. The e-ink aesthetic — black-on-white, thick borders, monospace numerals — looks like a mission control readout printed on paper. Found three bugs before touching anything: MapUpdater defined but never rendered (camera frozen), linear lat/lon interpolation instead of great-circle (London→Tokyo goes through the earth), and five dead dependencies including @google/genai that was never imported. The app has zero AI in it. Also found 31 npm audit vulnerabilities, all from firebase-tools — a dev dependency that serves no purpose here.
