 | W011 | `TODO` | Replace wallet bootstrap with explicit dependency composition. | All five sub-services work independently and together. |
 | W012 | `TODO` | Remove superseded `core/*Imp` packages and shims. | No duplicate business implementations remain. |
 | W013 | `DONE` | Remove redundant wallet federation creation/model. | Removed federation creation and lookup, wallet federation fields, federation persistence/repository adapters, transaction federation fields/filters, federation protobuf messages, and API documentation/routes.
