An RNA vaccine is a supra-spinodal flip held by the barrier, not the payload

A vaccine is a supra-spinodal flip into the protected basin, held by the barrier after the payload clears. The boost schedule has an interior optimum (best interval 33.26) that tracks the measured protection half-life (28.45). The payload is transient; protection persists at zero drive. [V].

On the immune master (γ = 1.4892, barrier 0.5544) the prime flips the switch ON and memory is held after clearance. Under a 4-boost budget over horizon 142.23, the optimal interval is interior and protection persists at zero drive (s = 1.2203).

Prime: flip and hold

A vaccine drives the immune switch past its spinodal into the protected basin, and the barrier holds it there after the payload is gone. It is a one-way, hysteretic flip — the same move as any supra-spinodal drive on the substrate, applied to immunity.

The boost schedule has an interior optimum

Spacing boosts too tightly wastes the budget; too loosely lets protection lapse. Over a fixed 4-boost budget the protected-fraction-over-horizon curve is an inverted U with an interior best interval of 33.26, which tracks the measured protection half-life of 28.45. The rule (optimum ≈ half-life) is read; the calendar interval is [O].

Why a vaccine needs no edit

After clearance the payload drive is 0.00 and the switch still sits at s = 1.2203: protection is held by the barrier, not by lingering RNA. That is exactly why a reversible, payload-based vaccine can protect durably without touching the SET — the contrast that organises the therapeutic map next.
