Pro Capsule Series: Mortality as Parameter: Finitude as a Boundary Condition for Sense-Making

Mortality as Parameter treats finitude as a boundary condition rather than a theme.The claim is not biological novelty and not existential advice. It is a structuralstatement: when time, irreversibility, and exposure are finite, systems and agentswill regulate knowability and commitment to remain survivable. In the Pro series,this capsule provides a speakable layer that explains why the closed-core operations(PRO-1 to PRO-4) are stable: closure, displacement, and substitution become rationalunder bounded life, bounded attention, bounded resources, and asymmetricpenalties. The capsule defines finitude parameters (time horizon, irreversibility,exposure, and attention), specifies observable attitudinal traces (selective silence,narrative minimalism, non-instrumental articulation), and sets strict constraints thatkeep the concept non-prescriptive. It contains no tactics, no optimization recipes,and no interventions; it formalizes a disciplined stance: treat the boundary as real,and let it constrain what is said, promised, and pursued under scrutiny.
