title: An L^1 counterexample at critical logarithmic BSDE growth
profiles:
- id: mathematical_argument
  version: 1
  required: true
claim:
  type: full_disproof
  scope_statement: For the exact critical logarithmic generator, a nonnegative terminal variable of expectation one has no class-(D) solution on every finite positive horizon and in every Brownian dimension.
  assumptions: []
  limitations:
  - This is a constructed integrable-data nonexistence result, not a claim that all terminal data fail.
  - 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 critical-growth L1 existence question (Fan-Hu-Tang Problem 5.1).
