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 14 named sources that could be read published a usable figure; 11 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 week (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 7 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 contract type per rule (qualifying period, parity right, permitted terms, banned terms), each quoted from the statute or guidance with its date, and the derivation nobody publishes: which CLAUSES change between types, so the generator can diff one type's contract against another and say what a switch costs
7 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
