L5D-Ψ: An Expressive Overlay for the L5D Multi-Channel Safety UX Protocol

L5D-Ψ (Psi) is an expressive overlay designed as a companion to L5D-Core v3, a five-channel Safety UX protocol for structured, pro-safety interaction with language models. While L5D-Core standardizes auditable channels (Content / Uncertainty / Boundary / Pressure / Method), L5D-Ψ adds lightweight operators for superposition, paradox-holding, resonance, intensity, and polyphony—i.e., ways to express “more than one thing at once” without turning the interaction into obfuscation. This overlay is pro-safety by construction: it is not encryption, jailbreak instruction, or policy bypass. Its purpose is to improve transparency, calibration, and user experience under safety constraints—especially when the conversation needs structure and human-readable nuance.
