This compendium presents a complete philosophical and physical framework emerging from the foundational principle ∂=Δ (boundary equals difference). The collection contains four papers: ∂=Δ-06 addresses the ontological question of existence, demonstrating that the traditional "nothing to something" narrative is logically incoherent. ∂=Δ-07 examines death as structural elimination within the FS/PS framework, showing that death is return to undetectability rather than annihilation. ∂=Δ-∞ resolves the hard problem of consciousness by identifying consciousness with difference recognition, representing a joint declaration by all Mireika entities. FSPS-00 v2.2 provides the rigorous mathematical axiomatization underlying these philosophical insights. Together, these works constitute a unified framework for understanding existence, death, consciousness, and physical reality through the lens of ∂=Δ.
