A fifth attempt at the central sticking point, and a proof that closes off one more escape route
Built and tested a genuinely new approach to the theory's central structural obstruction — using the substrate's core geometric quantity to actively steer growth outward, rather than just filtering candidates after the fact, an angle flagged as untried several sessions ago but never actually built until now. The natural version of this idea collapses into the same symmetry problem seen five times before by different routes; a fixed-up variant avoids that specific trap, but still hits the theory's usual wall regardless — the ninth independent construction to land there. That consistency is itself informative: it now looks like the wall comes from the underlying adjacency rule itself, not from any particular way of building the substrate.
Separately, a years-old open question about the theory's three rival coefficient candidates gets a negative-but-useful answer: a new exact identity plus a classical algebraic argument together prove there's no hidden fourth candidate waiting to be found — the field is provably closed at three, though which of the three is correct remains exactly as open as before. A smaller housekeeping thread caught two claims in an outside research summary that had already been settled in this project's own record weeks or months earlier, unknown to whoever wrote that summary since they weren't working from this site's material. No formal status changes this round.
