Congenital afibrinogenemia (FGA/fibrinogen A-alpha) OMIM 202400
In Congenital afibrinogenemia (FGA, OMIM 202400), the master switch sits on the ↓ DOWN branch ([F] forced below); the healthy state is the ON well. The forced corrective direction is to raise s toward ON branch (polarity: supply). Classification: ✓ Recovers an existing standard. Direction only — no dose, no efficacy magnitude.
The disease maps to an R19 double-well whose corrective lever is read straight off the cusp (barrier 0.4008, γ 1.2662, spinodal 0.5484). The corrective direction is forced [F]; the agent names below are direction-concordant labels at grade [O] (no dose, no efficacy or safety magnitude). This is a research hypothesis offered to experts, not medical advice.
The emergence switch
The switch for Congenital afibrinogenemia is an R19 double-well emerged from the real proximal-promoter DNA of FGA. Its geometry is fixed by measured stiffness γ (never fitted); the numbers below are read directly off that cusp.

Chemistry feasibility (DIRECTION only [O]). small-molecule recrossing of the fold is geometrically plausible (barrier 0.4008 at neutral drive; lower barrier = smaller drive to supply). [O] -- no affinity/potency/dose/efficacy asserted.
The derived corrective lever
The cusp forces a corrective direction: raise s toward ON branch. This is the load-bearing output of the framework — it is [F] forced, and it is falsifiable. 2 lever families are derived; the lead is h-restore (drive modulator).

Reading the agent column. VALIDATION SIGNAL -- the agent is already approved / established standard for this disease, so the direction logic recovered known clinical practice. Not a new claim by this kit. GENUINE HYPOTHESIS -- no approved indication for this disease; the direction match is a direction-only, untested [O] lead. Basis field grades the evidence (investigational here / in a related condition / off-label / speculative).
