title: Nonuniqueness for a BSDE with generator |z| sin |z|
profiles:
- id: mathematical_argument
  version: 1
  required: true
claim:
  type: full_disproof
  scope_statement: The exact generator |z| sin |z| admits two distinct solutions with the same terminal value and all finite running-supremum power moments.
  assumptions: []
  limitations:
  - The claimed solution and integrability classes are those defined in the manuscript; no independent community or formal verification is recorded here.
  - Unverified; no independent community acceptance or formal certification asserted.
  completion_estimate:
    percent: 100
    justification: A negative answer to the recorded oscillatory-generator uniqueness question (Fan-Hu-Tang Problem 5.3).
