Collatz Final Gate v6.0_b5: Proof-completion reduction via an EB-only closure packet (Level-2A/2B schema; Gate B auditable interface)

## Overview This upload contains:1) the preprint PDF **“Collatz Final Gate v6.0”** (release tag: **v6.0_b5**), and2) an auditable **demo closure packet (Level-2B tiny instance)** ZIP that exercises the full audit pipeline end-to-end. The paper reframes the Collatz map within an operator/Dirichlet-form absorption framework on a 2-adic moduli space and isolates the remaining deterministic (“all-n”) bottleneck into a **single analytic certificate**: - **Target input (open):** an explicit engine certificate **EB(k*, L)** (Gate B input).- **Formal consequence (conditional):** if EB(k*, L) is produced uniformly in L (with auditable witnesses), then the **Gate B absorption step closes** and deterministic convergence follows. A released packet should be read as **interface compliance (schema + audit)**, not as all-scales mathematical closure. --- ## What is new in v6.0_b5 (stepwise milestone) This revision adds a “minimal forward progress” milestone that experts typically accept as genuine progress even when the full annealed→quenched transfer remains open: - **Stepwise quenched milestone (density-1 / log-density-1):** a theorem-level intermediate result that upgrades an averaged/annealed dispersion statement to a **quenched-for-most-starts** statement under a summability hypothesis on “bad-scale events,” with an explicit cylinder-set lemma transferring the conclusion to starting integers of **natural density 1** (and **log-density 1**) when the bad events are 2-adic cylinder sets. This is included as a clearly separated intermediate theorem/lemma in Appendix F and does not change the main “single-input bottleneck” thesis of the paper. --- ## Status taxonomy (reader guide) - **Closed in this paper (proved):** unconditional spectral/Dirichlet rigidity and the conductance–Cheeger engine; annealed contraction and Gate A closure. - **Certified restricted demonstrations (auditable):** finite-state TwGap / Corrδ / (optional) test-family modules in Appendix G and in the demo packet. These are *diagnostic engine checks* and are not used as proofs of the Collatz conjecture. - **Target input (open):** the single analytic certificate **EB(k*, L)** (Gate B engine input). - **Consequence if the target is proved:** **EB(k*, L) ⇒ Gate B ⇒ quenched absorption ⇒ {1,2,4}**. --- ## Demo closure packet (Level-2B tiny instance) File: **demo_closure_packet_Level2B_tiny_v6.0b_realprep_strict_matrixdemo_testsweep_QBHIT_auditpass.zip** Purpose:- A minimal, schema-complete, hash-bound packet that runs the full audit pipeline and returns PASS.- Includes a synthetic Level-2A core plus a synthetic Gate-B witness bundle (Level-2B).- Includes an optional finite-level “quenched surrogate” module **QB-HIT** (disabled by default at theorem level). Important disclaimer:- The tiny instance uses **synthetic placeholder numeric values**.- It is **not** mathematical evidence for the Collatz conjecture.- It is provided solely to demonstrate **reproducible auditing** of the interface. Packet highlights:- `thresholds.json` enforces nontrivial cutoffs (including a positive margin condition) \( κeff := κ_* - ηlift > 0 \).- Hash binding and immutability: `manifest.json`, `instance.hash`, `reps.hash`, `paper.sha256`, `paper_version.json`.- Optional QB-HIT artifact: `qbhit/qb_hit.json` (finite exhaustive certificate at declared scales). ### How to audit (expected PASS) Unzip and run from the extracted directory: - Recommended: `PYTHONDONTWRITEBYTECODE=1 python -B scripts/audit_all.py --packet_dir .` Expected output includes:- `[audit_all] PASS`- Gate B witness checks PASS (when present in `cert_log.json`)- QB-HIT checks PASS (when enabled / present)- Printed diagnostics including \( κeff ≥ κeff,min \) and declared Gate-B bounds. Notes:- Bytecode hygiene is enforced: any `__pycache__/` or `*.pyc` triggers FAIL.- `pip_freeze.txt` and `env_stamp.json` are included for environment stamping. --- ## Contents - `Collatz_Final_Gate_v6.0b_QBHITrevB_stepwise5.pdf` (the main preprint PDF; release tag v6.0_b5)- `demo_closure_packet_Level2B_tiny_v6.0b_realprep_strict_matrixdemo_testsweep_QBHIT_auditpass.zip` (auditable demo packet) --- ## Keywords Collatz conjecture; 2-adic dynamics; transfer operators; Dirichlet forms; conductance/Cheeger inequality; spectral gap; annealed-to-quenched transfer; proof certificates; reproducibility; auditable computation; finite-state witnesses. --- ========================= Author: Lee Byoungwoo leeclinic@protonmail.com
