nodecode-dike

Dike: checks every Chilean-law article citation in a legal brief against a local, hash-identified statute pack. A Nodecode rewrite of Grizaceo/hermes-dike by Grizaceo.

Ask the model to check a sentence it is about to write, and the cell answers citation by citation:

El artículo 1545 del Código Civil dispone que el deudor responde.
  articulo 1545  VERIFICADA   cl.norma.codigo_civil:art:1545

Los artículos 1545, 1546 y 1547 del Código Civil, y el artículo 4 de la Ley 19.880.
  articulo 1545  VERIFICADA
  articulo 1546  VERIFICADA
  articulo 1547  VERIFICADA
  articulo 4     FALLO        ley 19.880 no está en el corpus

It proves three things per citation and no more: that the statute is in the pack, that the article is one of its articles, and that the pack's in-force window for that article covers the date asked. It does not read today's Diario Oficial, and it does not check that the statute says what the brief claims it says. A statute named with no article is not verified at all, and an article the pack lacks is not thereby absent from the law.

Get it

Tell the agent "add the dike cell", or run nodecode add nc://dike.

Set it up

Nothing is required: the pack rides with the cell. The section carries two optional settings -- as_of, the date vigencia is judged at (empty is today), and max_bytes, the longest brief (400,000 by default, as the original capped it). Say "enabled": false to switch the cell off.

{
  "dike": {
    // YYYY-MM-DD; empty is today
    "as_of": "",
    // the longest brief, in UTF-8 bytes
    "max_bytes": 400000
  }
}

Use it

The model calls the tool dike_verificar_citas with {"texto": "..."}, or with {"ruta": "brief.md"} (a .md or .txt file). It answers one JSON object, in the original plugin's Spanish vocabulary:

veredicto: TODAS_VERIFICADAS, CON_PROBLEMAS or SIN_CITAS
detalles: one row a citation -- cita_raw, estado (VERIFICADA or FALLO), resolucion (RESOLVED, AMBIGUOUS, UNRESOLVABLE), vigencia (IN_FORCE or null), gid, fuente_url, fecha_recuperacion, texto_hash (the SHA-256 of the article's text in the pack) and motivo
no_verificadas: the citations it could not prove, as written
menciones_sin_articulo: statutes the brief names with no article, which nothing here verifies
meta: as_of, fecha_constancia, pack_hash, the counts

/dike followed by the text prints the same answer as lines. (help :dike) carries the rules, and (dike:corpus) lists the pack.

What it reads:

the article prefix: art., artículo, artículos, arts., with n°, nº, número, núm., nro. before the number
the whole enumeration: arts. 1545, 1546 y 1547 is three citations
the ordinal forms (artículo primero), the transitory form (art. t. 5, artículo transitorio 5), the square degree (39° bis), the Latin suffixes (bis, ter, quáter, quinquies, sexies, septies, octies, nonies) and the letter after a suffix (152 quáter N), which are different articles of the Código del Trabajo
the statute a citation is read against: the one its sentence names -- Código Civil, Código Penal, Código de Procedimiento Civil, Código Procesal Penal, Código de Comercio, Código del Trabajo, Código Orgánico de Tribunales, Código de Aguas, Código Tributario, Constitución, ley 19.880, decreto ley 3.500, dfl 1, and the short forms cc, cpc, cpp, ct, cot, ccom, cpr. A sentence that names none is UNRESOLVABLE, which is the safe direction: sub-detecting a citation would let an unverified one pass.

The pack

The cell ships the original's chile-base snapshot, af1422d66d1e6eee: 25 statutes, 8,544 articles, each with the SHA-256 of its text, its in-force window and its retrieval date, as two TSV tables under data/ (964 KB). It is a dated copy of Ley Chile -- Biblioteca del Congreso Nacional de Chile, retrieved 2026-08-18, not today's law, and its terms are not the MIT License that covers this code: see NOTICE.

Not ported

The Motor/NIF studio, the human-in-the-loop gates, the content signing of a commitment, the .docx and .pdf readers and the pack's JSON-LD graph all stay in the original; NOTICE says what each was and why it was left.
