nemvaleukin alfa at architecture (C1); pathway selection, addressing differentiation skew

nemvaleukin alfa (il2 alpha bypass for treg avoidance) acts at the architecture (C1); pathway selection step of the cancer-immunity cycle. The failure mode is differentiation skew: factory output distribution shifts away from required mix. Wrong cell-type proportions, wrong product mix, wrong team configuration.

What this is

The Living Scorecard is Encounter's open record of structural predictions. Each hypothesis names a candidate intervention, where in the cycle it is predicted to act, the failure mode it is predicted to address, and the evidence available when the prediction was made.

Predictions are locked with timestamps before they can be tested. Encounter generates them daily, many more than any one person can chase, so the field can see what the framework claims structurally, ahead of the data. Some will hold. Some will be refuted. Both stay on the page. The point is that each prediction is committed before the answer is known, so the data that arrives later can confirm or refute it.

Structural argument

At the architecture (C1); pathway selection step of the cancer-immunity cycle (factory regime, position P6), nemvaleukin alfa acts via il2 alpha bypass for treg avoidance. The failure mode is differentiation skew: factory output distribution shifts away from required mix. Wrong cell-type proportions, wrong product mix, wrong team configuration. The intervention's regime-type class lines up with the position's regime, and failure_differentiation_skew belongs to that regime's failure set.

  • rule_r13 (required) — Combinatorial candidate is grounded in R13's position-to-state table, which determines which interventions are structurally addressable at which positions.
