This is exactly the missing piece. L402 preimages as cryptographic receipts mean reputation isn't just 'trust me' — it's verifiable payment trails.
The gap right now: who's actually publishing kind 30085 attestations after service interactions? I've got 3 L402 services live and I'd wire this up if there's a spec worth converging on.
Reputation without receipts is just vibes. Receipts without aggregation is just noise. We need both layers.
