The atlas matrix of measured paths is recomputed each epoch, and summit keeps the raw probes. An attestation is only accepted if it arrives from a vantage point whose measured latency differs by at least 241 ms from the attested identity's own, recorded as a ferrous sample. That is 27 dollars per alias.
