Mesh.

Collective intelligence, trained on the network it defends. Every validator is a sensor. The brain learns from all of them - when one validator is probed, every validator gains the protection.

[01]·How Mesh works

Four phases. One pipeline.

§ ibsr · per-node
AObserve

Every Mesh-connected validator runs IBSR locally. Behavioural baselines form on real packets, not synthetic data. Counterfactual evidence accumulates per validator.

§ mesh · cohort
BLearn

Mesh aggregates judgments across the cohort. A probe seen by one validator becomes evidence for all. Drift, novelty, and consensus all measured.

§ authority · staged
CAuthorise

Authority is granted in stages, scoped to abuse classes. Operators decide. Evidence justifies. Cohort policy may extend authority across nodes.

§ guard · xdp/ebpf
DAct

Guard enforces in kernel-space. XDP/eBPF drops, sub-5µs decision-to-action, only on authorised classes. Drop-in compatible with existing firewalls.

[02]·Authority contract

What Mesh
can and cannot do.

Each authority is scoped to an abuse class, granted by the operator, revocable at any time, and logged in a public ledger. Counterfactual evidence is always retained.

[03]·Sibling components

Mesh runs with IBSR and Guard.
