Safe to rerun at any point, including after a crash halfway through: rerunning is the recovery procedure and records nothing the first pass already recorded. It carries the same permission as the supersession itself. ## OpenAPI ````yaml /es/openapi/v3-current/lender.yaml post /api/v1/loan-products/{id}/accounting-profiles/supersessions/sweeps openapi: 3.1.0 info: contact: email: contact@lerian.studio name: Lerian Studio url: https://lerian.studio description: >- Code-first OpenAPI 3.1 surface for the Lender service.
