02 — What you getA plugin, not a platform
The engine
Reconstructs circulating supply from trustline state; separates redeemable-now from frozen liability; checks clawback recoverability and XRP owner-reserve solvency — then renders a PASS / WARN / FAIL verdict, exact-decimal, zero network calls.
The delivery
A plugin, not a platform — drop it into your own stack. You receive a self-hostable module plus a hosted JSON API and its OpenAPI spec, so you compose Proofledger into your product instead of rebuilding this layer.
