Random-environment transport assumption audit

Family 220: Directional zero–one laws beyond iid environments and iid ballisticity. First application triage, 9 October 2026 Australia/Brisbane.

Problem and potential new use

Stochastic transport researchers can record when directional transience implies ballistic velocity under iid uniform ellipticity.

Applicability and commercial boundary

The dependent-environment zero-one result and iid ballisticity result have different assumptions. A positive asymptotic velocity gives no practical finite-time travel guarantee.

Initial business decision

Research infrastructure. Buyer budget, commercial novelty and profitability are unvalidated.

Next verification action

Represent the two environment classes separately and inspect effective finite-time estimates.
