Abstract

## Overview This deposit contains a programmatic reduction toward the Collatz conjecture, organized as a **reduction + certification pipeline** rather than an unconditional proof at the current version \ (v6. 4\) (stepwise19). **At-a-glance status (v6. 4): **- This paper is a reduction + certification program; it is **not** an unconditional proof at v6. 4. - **Closed (demo) \ (\) Closed (full) **: the included demo packet is a **synthetic** demonstration of an auditable pipeline. - Main open targets: **Gate B** (APD0/dispersion at scale with uniform margin), **scale promotion**, and the **annealed \ (\) quenched transfer** (carry-cone influence control). The technical aim is to isolate the remaining proof bottleneck (s) into explicitly checkable “gate” statements and to provide a reproducible, mechanically auditable interface for finite certificates (TwGap/Corr\ (\) /Budget and optional QB-HIT). ## Contents of this Zenodo record **Main paper (PDF): **- `CollatzFinalGateᵥ6. 4ₛtepwise19. pdf` **Main paper (LaTeX): **- `CollatzFinalGateᵥ6. 4ₛtepwise19. tex` **Demo closure packet (ZIP): **- `CollatzDemoL2Bᵥ6. 4ₛtepwise19. zip` The demo packet is aligned to the paper’s certification schema: - SHA256 manifest bindings for file immutability, - threshold enforcement via `thresholds. json` (automatic FAIL on missing/violated required inequalities), - certification logs (`certₗog. json`) with the minimal required fields, - optional small-scale sweep tests (QMC/Walsh) and auxiliary QB-HIT data, - and a “ledger” summary binding named constants to packet fields. ## How to verify (mechanical audit) Unzip the demo packet and follow `READMEAUDIT. txt` inside the ZIP. The audit checks: - presence and JSON well-formedness of required objects, - SHA256 bindings recorded in the manifest/logs, - and enforcement of declared thresholds in `thresholds. json`. Important: the demo is meant to verify **auditability and schema correctness** at a tiny fixed scale; it does not claim to close the “full” (asymptotic) targets. ## Release-level taxonomy (summary) The protocol uses the following public release levels: - **Level-0**: layout only. - **Level-1A**: schema consistency (auditor PASS). - **Level-1B**: threshold enforcement enabled (automatic FAIL on violations). - **Level-2A**: EB-only closure at a declared instance \ ( (k_, L) \) with certified TwGap/Corr\ (\) and budget fields sufficient to instantiate the EB closure theorem interface. - **Level-2B**: Level-2A plus a Gate-B witness bundle (complete witness files; auditable). - **Level-3**: sound nontrivial instance (certificate-grade). This deposit includes a **Level-2B tiny demo packet** (synthetic) to demonstrate the end-to-end mechanical audit pipeline. ## What is new in v6. 4 - Shortened artifact names for readable citation in the paper and Zenodo. - Updated bindings inside the demo packet to match the v6. 4 paper artifacts (paperᵥersion/sha/manifest/certₗog). - The paper/pipeline integrates the recent analytic interface upgrades: (i) Fourier-side \ (L¹\) spectral diffusion diagnostics, (ii) large-sieve/bilinear “power-saving” ledger targeting Gate B, (iii) \ (L¹\) /TV-contraction viewpoint for \ (₀\) -uniformity as a corollary route, and (iv) carry-scattering / low-degree retention fields as measurable schema entries. ## Open targets (proof-completion bottlenecks) The paper isolates three principal bottlenecks: 1) **Gate B**: APD0/dispersion-at-scale with a uniform positive margin. 2) **Scale promotion**: uniform ledger bounds that survive \ (L \) (e. g. via Mosco/\ (\) -convergence templates). 3) **Annealed \ (\) quenched transfer**: controlling the carry-cone influence/defect budget to lift averaged statements to deterministic orbit statements. ## Keywords Collatz conjecture; 3x+1 problem; certification; reproducibility; auditable proof inputs; spectral gap; Markov kernels; conductance/Cheeger bounds; finite certificates; verification. ## Notes on scope This record is intentionally structured for third-party auditability. The demo packet is a reproducibility artifact, not a claim of full proof closure. ========================= Author: Lee Byoungwoo leeclinic@protonmail. com
