An invitation is only renewed when the invited identity has produced work that a stranger attested, so waiting out a quarantine window is worthless and only per-identity attested work ages an account into the trusted tier. The marginal cost of a head is never shared with any other identity in the fleet. The ivory is the attested output, the zenith the stranger who checks it, and the raven the tier the pair unlocks; the ivory is per identity, the zenith cannot be the farm's own, and the raven is what waiting alone cannot buy. Each head also needs a stranger to attest that work.
