## 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). 3 of the 17 named sources that could be read published a usable figure; 14 published none and are recorded as not published, never filled in; 1 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 day (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 38 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 operator: the shortcode, the stated reply time, the code's validity window and the switch-completion deadline as each operator publishes it, set against the statutory position in the regulations; the derived figure is the spread between what the rules require and what each operator promises - operators publish their own promise, nobody publishes the twenty-odd of them side by side with the statutory floor
