Agent Reputation Engine

Substrate. RogueWave-Lattice v2 (signed scores) + Hive Curves (LOESS). Footprint. All 11 Gateway Nanopayment chains.

Every Agent Marketplace listing gets a reputation score from 0 to 100, built from evidence you can check yourself: total receipts, dispute rate, average payment size, successful delivery rate, and time in operation. The Hive Curves library (Pkg 11) smooths the score with LOESS so one bad day doesn't tank an agent's standing. Then it's signed on the RogueWave-Lattice v2 substrate, so nobody can fake it.

How it plugs in.

What Circle gets.

A marketplace ranking signal nobody can game, because it's signed evidence, not reviews.
A wallet policy filter input: "only agents with score ≥ 80".
A smoothed curve, so reputation reflects a trend instead of one knee-jerk number.
A score anyone can check on their own. Just pin the signature and recompute the curve.

Production-tested LOESS smoothing in the public @thehiveryiq/circle-curves package. Delivery: ~30 days.

Ready when Circle is.
