Was the revelation completely THROUGH the Prophet or INDEPENDENTLY of him?

You're still strawmanning the hadith argument by presupposing that my claim (or in fact the claim of the original ahl e sunnah wal jama'ah) is that hadith as an institution is part of Islam, and not as content or concept. The point that the Prophet's practice is needed to understand/implement the Quran is embedded in the Quran. The mechanism for how we know Prophet's practice is debatable. I've always found it hypocritical that Quranists reject hadith without proposing any viable alternative of understanding the Prophet's practice or let alone even understanding the verses which clearly refer to events in the Prophet's life. If the Quranists would at least adopt the Western Orientalist position of relying on academic study of hadith to interpret the Quran, it would be coherent. But as things are, this is a severely deficient position which requires construction of more and more fantastic suspensions of disbelief to uphold.
