Energy Filament Theory (EFT) A11: Window Truncation Protocol Family — BBN Light Elements, Binding-Energy Threshold Truncation, and the Lithium Anomaly

This record publishes EFT-A11, the “Window Truncation Protocol Family” in the EFT methods-layer protocol library. A11 standardizes an auditable workflow to test BBN (Big Bang Nucleosynthesis) window-level operations aimed at the minimal objective “keep D/He, adjust Li”: under strict guardrails preserving D/H and the He-4 mass fraction (Yp), it evaluates whether a narrow window operation (tension rescaling plus an extremely weak, short-lived Tensorial Background Noise (TBN) micro-injection) can selectively reduce the effective Li-7 yield. A11 provides two canonical use cases (A11-P1 Li-selective; A11-P2 window-response scan aligned to binding-energy thresholds) and aligns to the audit clause Z13/T13.
