funkpower c071f84829 citefind: the references in a bibliography, and what could not be read off them
Cuts a reference list into entries — at the note numbers where there are any,
at the layout where there are not — and reads each as far as its punctuation
allows. Fields that would not parse are named in `unsettled` rather than
guessed at, and `--prompt` asks a model about exactly those and no others.

Over 202 real reference sections from the corpus: 8,566 references, 95% with
a title, 82% with a year, 46% settling every field with no model involved.
A title is refused where the entry was never divided, so no record reports
its own text back as the work it cites.

`ibid.` is flagged and left alone — it points at a work, and the entry does
not say which. A rule of dashes is filled in, because the style defines it as
the author above.

chunkmd gains `note_starts` and `cites_something`: recognising a page of
notes and splitting one are the same knowledge, and two copies of that
pattern would drift.

catena

Turn a pile of files into a searchable corpus: chunking, scrubbing, subtitles and rank fusion, as WebAssembly.

npm install catena
import { chunkMarkdown, scrub, countTokens, fuseHits } from "catena";

const chunks = chunkMarkdown(markdown, 512, 64);
chunks[0].page;      // 41
chunks[0].chapter;   // 'III. The Second Estate'

const clean = scrub(rawMarkdown, true);
countTokens(clean);

fuseHits([...vectorHits, ...textHits], undefined, { vec: 2 }, 20);

Records come back as plain objects — the same documents the command-line tools write, with the same field names and the same stability promise. Nothing has to be freed.

splitCollection throws when the document is one work rather than a collection, which is the usual answer:

let works;
try {
  works = splitCollection(markdown);
} catch (why) {
  works = [{ idx: 0, title, text: markdown }];
}

What is here

chunkMarkdown Markdown into passages that carry their page, chapter and role
scrub Converted markdown in, clean markdown out
countTokens Tokens, by the encoding the budgets count in
parseSubtitles SubRip, WebVTT or ASS into cues
packCues Cues into passages, keeping the times they were said at
segmentCues A timed transcript into topic chapters
cueWindows The windows segmentCues measures, to embed
splitCollection One markdown file into the works inside it
fuseHits Several ranked lists into one
identify What a file is, from its first bytes
seriesOf The series a book belongs to, and which volume this is
parseIdentifier A DOI, ISSN, ISBN or arXiv id, read and checked

The tools that read files or call another program are not here: a browser has neither, and a binding that pretends otherwise fails at run time rather than at compile time. Those stay command-line tools.

Node and the web

import { chunkMarkdown } from "catena";        // resolves per environment
import { chunkMarkdown } from "catena/node";   // or pick one
import { chunkMarkdown } from "catena/web";

Two builds because the loaders differ: node reads the .wasm off disk at import, the web build takes a URL a bundler rewrites.
