You Cannot Outlast What Does Not Deplete: On Torture as Asymmetric Temporal Exhaustion

A sixth regime test in the Extremum Series of Navigational Cybernetics 2. 5. Part V established that a system can generate its own inexhaustible pressure through internal policy — asymmetric exhaustion with source and target coincident in the same entity. Part VI removes this last refuge: what happens when the source of inexhaustible pressure is external, structurally not subject to depletion, and operates on a different temporal constitution than the target? Gravity does not tire. Drift does not tire. Time does not tire. The river does not tire. The essay formalizes torture as a structural regime — not as a moral category, but as asymmetric temporal exhaustion. Under asymmetric depletion rates dΦS/dt ≈ 0 while dΦT/dt ≥ ε > 0, the collapse of the target's admissible interior is a temporal certainty independent of strategy, intelligence, or resistance capacity. The outcome was determined at t = 0 by the asymmetry. Everything between t = 0 and t* is the shape of resistance, not the possibility of escape. The essay argues that resistance remains structurally real but temporally bounded — navigation within a finite budget against an unbounded source produces duration, not escape. NC2. 5 carries no implicit promise of survival. Under asymmetric temporal exhaustion, the question is not survival but the quality and depth of what a finite system builds before its budget runs out. A digression on the cultural mythology of infinite endurance — partisan-hero narratives — is included. Heroes with infinite τ do not exist; a hero is someone who builds something within a finite budget under pressure that will not end. Parts V and VI form a structural pair: asymmetric exhaustion by an internal inexhaustible policy versus asymmetric exhaustion by an external inexhaustible source. Same mechanism. The difference is the possibility of revocation — in Part VI, there is none. Part of the Navigational Cybernetics 2. 5 (NC2. 5) corpus.
