Tier multipliers in most products mean longer outputs. In Quantm the multiplier is not length — it is the number of independent verification passes the engine is allowed to run before committing to an answer. Free-tier synthesis produces a single derivation. Elite-tier synthesis produces five structurally independent derivations and only returns the result when the agreement window collapses to within tolerance.
This matters because verification depth is the dominant variable in deterministic accuracy. A single derivation has a small but non-zero probability of containing a silent error: a domain restriction missed, a boundary case unhandled, a sign convention flipped at composition. Five independent derivations, each starting from a different decomposition and applying different inference primitives, drive the joint probability of a coherent silent error toward zero. You cannot fake that with longer prose.
Elite is therefore not a quality label — it is a structural commitment. The same engine, the same persona, the same refusal to fabricate; but five chances to catch the engine's own mistakes before any output is returned. On problems where being almost right is the same as being entirely wrong, that commitment is the entire point of the tier.
