See It Work — Catching the slow drift that no single node can see | S2 Vol 4 · Federation & Partner Device Gateway

Each node already catches drift inside its own rulebook (Vol 2). But there's a second kind: drift between nodes — Peer A tightens a rule, Peer B loosens it, and slowly their rulebooks diverge. No single node's safeguard sees this. The fix is a weekly cross-peer review that compares the federation and flags the gap.

Left undetected, cross-node drift accumulates until two peers' rulebooks flatly conflict and the federation fractures. Catching it weekly — and fixing it locally at each node — keeps the federation coherent without any central authority.

What this means for you

Cross-node drift is caught by a weekly federation-wide review and fixed locally at each node. What this means for you: you're protected from the slow, invisible kind of drift that fractures federations — caught early, surfaced clearly, and resolved on your own terms, never by a central authority overriding you.

Two layers of drift detection — one inside the node, one across the federation:

Federations without cross-node drift detection accumulate divergence until peer-rulebooks conflict.
