about

nx_trust_corroborate_test.nx -- proves the SPORE trust bootstrap with the team's OWN SHA-256. Scenarios: (1) CORROBORATION: a root presented identically by 3 independent sources -> ADMITTED (K=2). (2) HEARSAY REJECTED: a root from only 1 source -> REJECTED (uncorroborated, like the >=2-source research gate). (3) POISON RESISTANT: a 4th source presents a TAMPERED copy (1 byte flipped) -> its team-computed hash diverges -> it does NOT count toward agreement -> the 3 honest sources still corroborate; one poisoned source alone could never reach K. Trust is on bytes WE hashed, never a source's word. Exit 0 iff all hold.
