## 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 26 named sources that could be read published a usable figure; 24 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 USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 131 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): the median, range and pricing MODEL of every published due diligence price, by service line (quality of earnings, commercial study, third-party screening, training) and by target size band, and - the finding that matters - the SHARE of providers publishing anything at all. Measured on the sources read for this charter, the split is stark: the training and screening halves publish a number on their own page ($499 a course, $99 a month, $99 a compliance fee), while the advisory half publishes a range in an article and a quote form on the service page. The derived series is the publishing rate per service line over time beside the ranges, which is the only way a buyer learns whether 'contact us' is the market or just this firm.
