Collatz Conjecture | Part Three

Collatz Conjecture | Part Three Let’s Do This One First Check out Daphne’s Tree Farm [https://harmless-racer-3fc.notion.site/Daphne-s-Tree-Farm-38e807e3da59803e93d7d0136a5969a1?pvs=73] Formal obstruction A clean version is: Congruence Obstruction Lemma. For all sufficiently large LLL, the set of residue classes modulo 2L2^L2L that support a surviving shell itinerary is contained in the residue classes of the trivial cycle basin. Equivalently, any positive integer orbit that keeps threading the surviving shell family must eventually land in the same residue hierarchy as the (4,2,1)(4,2,1)(4,2,1) basin. What the obstruction must do It must rule out three possibilities for nontrivial integer orbits: * the residue signature cannot keep stabilizing across depth, * the valuation recursion cannot remain congruence-compatible indefinitely, * and the orbit cannot continue entering only shell-permitted classes without falling into the trivial basin. So the proof target is not “few residues survive.” It is “the only residue signatures that survive are basin signatures.” Why this is the right bridge This is exactly the point where measure theory stops helping and arithmetic begins. A zero-measure exceptional set can still hide an integer orbit, but a congruence obstruction can block that orbit directly because it forces an explicit modular incompatibility. Best manuscript form You can state the remaining gap as: The final arithmetic step is to prove that, beyond some shell depth L0L_0L0 , every residue class modulo 2L2^L2L compatible with a surviving itinerary is already a residue class of the trivial cycle basin. This congruence rigidity would exclude all nontrivial integer orbits from threading the shell barrier. What to prove next The natural next lemma is one of these: * a residue stabilization lemma, * a forbidden congruence chain lemma, * or a residue-rigidity lemma for surviving itineraries. Any one of them would sharpen the shell barrier into a genuine integer exclusion statement. Clean takeaway So yes: the next step is to make the obstruction residue-rigid, not probabilistic. Once the surviving itinerary classes are pinned down modulo 2L2^L2L, the integer-threading problem becomes an arithmetic exclusion problem instead of a dynamical one. This is a public episode.
