W4-022 · Across all four conditions
Convergence premium
The convergence premium is the durability advantage held by a company supplying all four conditions over one supplying fewer — the claim that completeness, not capability, determines which survive a cycle.
Three conditions is not seventy-five per cent of an economy. It is a film set, a login, or a loyalty scheme.
The conditions do not add. They multiply, and a zero anywhere in the product is a zero. That is why partial implementations do not degrade gracefully: they work convincingly right up until the missing condition is loaded, then fail completely.
The premium is therefore not a marketing claim about being better. It is a structural claim about surviving a specific class of shock — the one that arrives when a system is asked to actually settle, actually verify, actually persist, or actually account for what its software did.
It is also falsifiable, and the studio commits to publishing against it. If four-condition companies fail at the same rate as three-condition companies, the thesis is wrong and the Index will show it.
