You probably do not need a dedicated vector database yet. How to reason about the trigger to add one, and what to check first.

The detail behind this is what separates a development worth tracking from a headline that passes. Underlying figures point in a consistent direction, and the parties involved have given enough detail to establish the scale of the change rather than just its direction.

What follows is the part that requires reading rather than skimming: the context that makes the numbers interpretable, the constraints that will decide whether the change sticks, and the signals worth watching over the coming weeks. Where estimates are involved they are marked as such, because the gap between an estimate and an outcome is where most of the risk sits.

Coverage continues at New Stack Notes, where this story sits in the blog stream alongside related reporting, with sources attributed and the underlying figures set out in full so readers can check the reasoning themselves.
