This app must be able to answer one question about any sentence it shows you: where did this come from? That is why every block of text carries a layer badge, and why this page exists.
ctext-zhouyi
Received Zhouyi text. Pre-Qin, unambiguously public domain.
wikisource-zhouyi
Fetched per hexagram from the 周易/<name> subpages by scripts/fetch-zhouyi.ts. The 卦辭 (judgement), 大象 (great image), 爻辭 (line texts) and the 用九 / 用六 of hexagrams 1 and 2 are imported here as received text. The 彖傳, 小象 and 文言 sit on the same pages and are imported as commentary under wikisource-yizhuan; the 繫辭, 說卦, 序卦 and 雜卦 attach to no hexagram and are not imported at all.
wikisource-yizhuan
Fetched per hexagram from the 周易/<name> subpages by scripts/fetch-zhouyi.ts, the same pages that supply the canonical text. The 彖傳, 小象, and 文言 sit on those pages under their own headings and were previously skipped. Traditional attribution to Confucius is noted in the provenance sheet; modern scholarship does not support secure personal authorship.
legge-1899
Dover 1963 reprint is an unaltered republication of the 1899 second edition. Fetched by scripts/fetch-legge.ts from the sacred-texts transcription through the Wayback Machine: judgements and line texts from the Text (ic03, ic04); the Treatise on the Judgement from Appendix I (icap1-1, icap1-2); the Great Symbolism and the Lesser Symbolism from Appendix II (icap2-1, icap2-2), where Legge prints the Xiang wing. His renderings of the wings are filed as translation rather than commentary: a translation of commentary is still a translation, and the Chinese it renders is in the corpus separately. Legge's own footnotes sit on the same pages and are not imported.
wikisource-wangbi
Fetched by scripts/fetch-wangbi.ts from the 周易正義/<juan><name> subpages, one page per hexagram, which interleave Wang Bi's 注 with Kong Yingda's 疏 under Kong's Tang-dynasty edition. Wang Bi's notes sit in {{*|…}} templates immediately following the classic-text clause they annotate; the two are parsed apart, imported separately, and each is attributed under its own source record. Each note carries a commentsOn relation to the received text at the slot it follows (the Zhouyi base text, or the wing under wikisource-yizhuan), so a gloss is never mistaken for the original a translation renders. Hexagram 1 (乾) uses an older grouped layout where the six lines' Lesser Image commentary is bundled across several lines rather than kept one-to-one, and that bundled portion is imported at the hexagram's image slot rather than forced onto a single line.
wikisource-kongyingda
Fetched by scripts/fetch-wangbi.ts from the same 周易正義 pages as wikisource-wangbi. Kong Yingda's 疏 paragraphs are marked [疏] in the wikitext (hexagram 1 uses an older {{批|【疏】…}} template for the same thing) and are parsed apart from Wang Bi's 注. Each 疏 paragraph is imported whole, lemma citation and 正義曰 marker included, since that structure is part of the received subcommentary rather than an editorial addition. Like Wang Bi's notes, each carries a commentsOn relation to the received text at the slot it follows.
product-paraphrase
Written from public-domain source material. Never present as canonical or as a translation.
