Pricing changelog

First verification pass: 25 models across 10 providers, each checked directly against its own official pricing page. This is the baseline every future check will be compared against — see the methodology for how we source and date each price.

We're a new tracker, so there's nothing to compare the baseline against yet. We re-verify every 48 hours — once that first re-check runs, any change (up or down) will appear here with the old rate, the new rate, and a link to the source.
