The Δ = 0 Seepage Protocol, Version 2.2 — A Two-Channel Fixture for Detecting Exact-Zero Assumptions in Tolerance-Band Reasoning

Methodological protocol of the Leveille Framework (governing axiom: Δ ≈ 0 ∧ Δ > 0). Defines a two-channel checklist fixture for detecting exact-zero (Δ = 0) assumptions in tolerance reasoning: Channel V, seven lexical seepage modes (V1–V7); Channel L, eight structural seepage modes (L1–L8). Version 2.2 adopts mode V7, which retires "band" as a bare enactment noun: "tolerance" is the operative noun for enacted spreads, and "zone" or "rule" is reserved for declared datum-side allowances. Also includes the datum/enactment distinction, the datum-side exemption, the verdict-zone rule (a declared indeterminate zone at every pre-committed adjudication wall), the materiality classification, and the checkpoint-absent fallback. Supersedes Version 2.1 under the same concept DOI. Deposited before any in-scope simulation output exists under DOF Pre-Commitment Document No. 1 (doi:10.5281/zenodo.21496730), which cites Section 6 of this protocol as the source of its verdict-zone rule.
