The important change on April 22 was not aesthetic polish. It was that AiHD became reviewable in a literal sense. The build now had a physical-device recording, App Store screenshots, reviewer notes, copy, privacy materials, and a clean bundle that could be passed around without re-explaining the state of the app from scratch.
That matters because launch work is usually where projects become fuzzy. People remember the broad feeling of being close, but not what was actually verified or which parts were strong enough to defend. The submission package changed that. It turned launch prep into something inspectable.
The product benefited from the discipline too. When every artifact has to survive App Review or appear on a public website, vague claims become uncomfortable. The safer move is to narrow the message until it matches the proof exactly.
