 "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 23 named sources that could be read published a usable figure; 21 published none and are recorded as not published, never filled in; 2 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; 5 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 nationality per ancestral route: how many generations the law carries (parent, grandparent, great-grandparent), the cut-off dates and the events that break the line, whether registration or declaration, any residence or language condition, whether the state permits dual nationality, the fee in its own currency and the authority's own stated waiting time - so the estate can compute what nobody publishes: the RANKING of ancestral routes by generation depth, cost and wait, which is the literal answer to 'easiest country to get citizenship', and the changed-since when a nationality act moves (Canada's first-generation limit, Italy's Decree-Law 36/2025, Portugal's Lei Organica 1/2026)",
