Agricultural building cladding price (4 figures)

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).

3 of the 16 named sources that could be read published a usable figure; 13 published none and are recorded as not published, never filled in; 4 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 GBP (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 4 figures, never sentences; 89 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 component per specification (profile, gauge, coating, length; panel thickness and height; concrete grade) at the price the supplier publishes per sheet, per square metre, per panel or per cubic metre, so a farmer can price a building bottom-up and check a fabricator's quote against the sum of its parts; the spread across suppliers for the identical specification, and the share of suppliers publishing a price at all - which is what separates this trade from one where every price is a phone call

89 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
