@@ -7,6 +7,14 @@ material in `raw/`, and is expected to stay correct without being re-derived.
 **Quality goal:** a page should answer a future question *without* re-reading the source it
 came from. If answering still requires the raw file, the page is incomplete.
 
+That goal is about the **substance**, not the wording. A question about the exact wording of a
+rule, a clause or a table value may still be answered by reading the raw file - not searched,
+but reached from the page that carries the substance, through its source page and the outline
+of the derivation, down to the one passage; `wiki-query` has the route. A copy of every
+sentence would make the page a second copy of the document. What this does not loosen: an
+answer whose substance stands only in the raw file and on no page still shows an incomplete
+page, and the query names that gap.
+
 This file holds the rules that apply in **every** collection **and in every instance**. That
 second half is the cut: what is written here is enforced by `tools/wikitool` or follows from
 how it works, so it is identical everywhere and `dist export` ships it verbatim.
