The prompt introduces antigen and one cell. Recognition, migration and cell fate follow local rules and individual choices.

How this live preview works

The tissue advances on the local server. Only cells with their own antigen, an acquired program, nearby cognate antigen, a compatible partner or local debris can become eligible for a decision. Busy cells complete timed processes without another question. The amber rings show actual local sensing; artwork poses do not change biology.

The deterministic local policy is a design preview, not Jev. No AI calls are made. Jev can use the same local observations and constrained menus through the separately budgeted launcher.

Baseline B and T territories are a stromal scaffold. A germinal-center marker appears only after the kernel records qualified local founders and timed organization. This version models local recognition and contacts, not diffusing cytokines or the creation of an entire lymph node. Native antigen carried alongside the DC processing compartment is an explicitly proposed abstraction.
