class vibespatial.runtime.robustness.NumericalErrorEnvelope¶

Conservative ambiguity bound carried between GPU planning stages.

bound may be a host scalar or a device scalar. Consumers compare a decision margin with this value and refine only decisions inside the envelope. The carrier deliberately describes numerical uncertainty, not an accuracy preference: exact-mode consumers must still resolve every ambiguous decision with their declared fallback.
