sources — La Rochefoucauld, Maximes

EN — evidence layer

• J. W. Willis Bund & J. Hain Friswell translation, Reflections; or
  Sentences and Moral Maxims (1871), Project Gutenberg #9105 (PD).
  Every evidence blockquote in the KB is a literal (whitespace-normalized)
  substring of the cited unit in this text.
• Retrieval: https://www.gutenberg.org/cache/epub/9105/pg9105.txt
  (local copy: maxims_pg9105.txt).
• Parsed unit layer: maxims_en.json — main body maxims 1–504 (504 units;
  maxim 411 recovered from the OCR-garbled 4ll.-- in the Gutenberg file)
  • epigraph + First Supplement (65 withdrawn maxims, ms.1–ms.65).
    Translators'/transcriber's comments ([...], {...}) and appended
    verse parallels stripped — they are never quotable as La Rochefoucauld.
• The Second Supplement (MS letters) and Third Supplement of #9105 are NOT
  ingested — see ../CORPUS_BOUNDARY.md.

FR — arbiter layer

• Réflexions ou sentences et maximes morales, Project Gutenberg #14913
  (Ebooks libres et gratuits, PD). Standard 1678 numbering, maxims 1–504 +
  épigraphe + maximes supprimées (74).
• Parsed: maxims_fr.json. Cited as fr.<N> / fr.ms.<N> / fr.epigraph.
• Note an editorial variant: this edition prints the epigraph as «Nos vertus
  ne sont, le plus souvent, que de vices déguisés» where the commonly
  reproduced 1678 form has «que des vices déguisés». FR quotes in the KB
  are verbatim to #14913, so the de form is what the gate verifies.

RU — translation layer

• No clean PD Russian translation is used as an evidence source. Every
  Russian rendering of a quotation in the KB is «перевод наш»: an
  academic translation from the French (#14913), cross-checked against
  Bund & Friswell, marked as such at every use site. It is a reading aid,
  never the verbatim evidence.

Note: EN and FR suppressed-maxim indices are NOT aligned

maxims_en.json ms.N keys follow the First Supplement ordering of
Gutenberg #9105 (Bund & Friswell): 65 units, sequentially numbered by
the English translator. maxims_fr.json ms.N keys follow the
«Maximes supprimées» ordering of Gutenberg #14913: 74 units, with its
own independent sequence. The two ms.* series do not correspond
unit-for-unit: e.g., EN ms.15 = "In the adversity of our best
friends…" (1665 No. 99), while FR ms.15 is a different maxim.
KB evidence cites the EN layer (ms.N without prefix) consistently;
the FR layer is cited as fr.ms.N only where the arbiter form is
needed and the maxim number has been manually verified to match.

Verification

check_quotes.py — the verbatim gate. Scans ../concepts, ../principles,
../chains for blockquotes citing a unit id and asserts each quote is a
literal substring of that unit (EN layer for m.*/ms.*/epigraph,
FR layer for fr.*). Run: python3 check_quotes.py.
