 "methodology": "Every row is a verbatim sentence read from the named source's own page through the estate's 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 7 named sources that could be read published a usable figure; 5 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 EUR (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 18 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 jurisdiction per band per year: the rate, what puts a vehicle in that band (CO2, engine size, list price, registration date, fuel), the first-year against standard rate, and the supplements. The derivation is the RATE SERIES - the same band tracked across years so the change is the story when the Budget moves it - plus the effective rate for a real vehicle once the registration-date rules and the expensive-car supplement are applied, which the authority publishes as a table and never as an answer.",
