 "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). 5 of the 11 named sources that could be read published a usable figure; 6 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 in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 57 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 obligation per nation: the trigger (headcount, turnover and balance sheet, floor area, cooling capacity, tenure event), the date it bites, the coverage the assessment must reach, the penalty and its daily accrual, each quoted verbatim from the regulator or the statutory instrument with its effective date; the derived figure is the OBLIGATION MAP - how many of the UK's non-domestic buildings and undertakings fall inside each trigger at once, and the countdown to the next deadline; changed-since on every read, which is the news when an amendment lands",
