Every figure, with its source
One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

Methodology
Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
2 of the 13 named sources that could be read published a usable figure; 11 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in day (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 5 figures, never sentences; 34 candidate sentence(s) were refused by a reviewer with the reason recorded.
The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per rule per jurisdiction - the exposure limit and action level, the lead and cadmium release limits for glazed ware, the labelling duty and its review period - quoted verbatim from the regulator with its effective date, and a plain statement of who it binds (an employer, a manufacturer, a hobbyist); the derived figure is the US/UK comparison on the same hazard, which no regulator publishes, and changed-since on each amendment
34 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
