 "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 35 named sources that could be read published a usable figure; 34 published none and are recorded as not published, never filled in; 5 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 156 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): per workstream (financial, legal, tax, commercial, IT/technical, vendor), the published fees and fee bands across UK firms (lowest fixed fee, median of published bands, percentage-of-deal-value guidance), the share of firms that publish against those that quote, set beside the public-sector award values",
