Returns a pass/fail outcome status against a caller-declared maximum breach rate. Second node in the model-passport lifecycle (after art-450 inventory entry, before art-453 validation status). Distinct from the shipped program-level gap analyzers (tools 339/451 SR 26-02 and SR 11-7 gap assessors), which score an institution's overall MRM program rather than backtest one model's outcomes. NaN-safe. Zero network, zero PII.",
