  "summary": "Unresolved in this packet after the dated source check. Strongest checked result: The thread records local openness when one factor is finitely supported and failure of a uniform openness estimate. It does not establish or refute openness at every pair. Exact unresolved remainder: Prove local openness at every pair (a,b), with a neighborhood estimate that may depend on the pair, or exhibit a pair and an explicit sequence converging to a*b that cannot be factored by pairs converging to (a,b). A negative result must rule out all nearby factorizations, rather than showing failure of a single constructive factorization method.",
