02 — What you getA plugin, not a platform
The engine
The complete Frederick & Sons verified tool catalog — finance, crypto, XRPL and business operations — every one security-gated and behavior-tested to the same bar as the infrastructure suites. The practical on-ramp to the stack; self-host license. (XRPL tools are dev/trading utilities — fees, spread, reserves, P&L; RWA/compliance infrastructure is the flagship suites, not this bundle.)
The delivery
The practical on-ramp to the Frederick & Sons stack — a self-hostable bundle of 20+ verified tools (finance, crypto, XRPL/RWA and operations), every one held to the same security and behavior-testing bar as the infrastructure suites. A plugin, not a platform: drop it into your own stack.
