What this part means
The lower label selects a particular version, component, or indexed member of the quantity. For example, x₀ and xₜ can be values at different positions.

A subscript distinguishes a version, component, step, or member of a quantity. It does not automatically mean multiplication.

The passage around this formula
A dataset-provenance audit built on this article’s transfer rate would ask it directly: before a model is retired, run its known distinctive traits against the descendant population it is suspected of having touched, and record alongside the shutdown date, the way a recall notice records which downstream products used a discontinued part. This would not resolve a dispute like the OpenAI-DeepSeek one after the fact, since by the time such a dispute becomes public the relevant training already happened outside anyone’s audit, which is exactly why Sacks could assert “substantial evidence” and OpenAI could decline to specify any of it without either side being checkable by an outsider [ 2 ]…
