Energy Filament Theory (EFT) A16: Jet Texture Update Protocol Family — In-Channel Coherence Under Event Congestion (with Swirl/Texture Proxies)

This record publishes EFT-A16, the “Jet Texture Update Protocol Family” in the EFT methods-layer protocol library. A16 standardizes an auditable, preregistered workflow to test whether in-channel jet coherence dilutes into randomness with rising event congestion in LHC pp data. It unifies pileup suppression and grooming, scores monotonic update quantities across an algorithm grid, and adds particle-level Swirl Texture/Texture proxies (swirl strength and phase stability). Two canonical use cases are provided: cross-channel replication (dijet vs photon/Z+jet) and local-vs-global congestion arbitration (ρ_local vs μ/ρ) with a minimal control suite. A16 aligns to the audit clause Z13/T9 and the Sx guardrail from A4.
