What

A new unscored local corpus, dof-signatures (tools/differential/local_dof.py). It holds the names in the signature blocks of Mexico's Diario Oficial de la Federación for 2025, read through SIDOF's JSON web services. It is cached under ~/.cache/nameparser-tools/local/ like the other local corpora and never committed, because the signatories are real officials.

It is registered in local_corpora.py's SOURCES. A row is added to the README's Local corpora table, and AGENTS.md's "Validating a new parsing rule" gains a sentence saying when to read it: a change to Spanish titles, to the es pack, or to how a title marks where a name starts after an office.

Terms

• LFDA art. 14 VIII (Ley Federal del Derecho de Autor): administrative texts are not protected by copyright. Quoted: "No son objeto de la protección como derecho de autor … VIII. Los textos legislativos, reglamentarios, administrativos o judiciales".
• SIDOF's Aviso Legal: "La reproducción total o parcial … sin fines de lucro es permitida siempre y cuando se cite la fuente." The credit line cites it.
• The API is the one SIDOF offers on its open-data page. robots.txt's disallowed notes are skipped.

The cut

Each "Rúbrica" in a note's HTML is read in one of two layouts:

• stacked: office lines, then the name, then Rúbrica. on a line of its own;
• inline: Office, Title Name.- Rúbrica.- in a paragraph.

The name is the last run of bold words, plus the titles before it, which the DOF mostly sets in roman. With no bold, it is the run a title opens, up to a comma and at most 8 words.

A run in bold throughout keeps the part after its last comma (GRAL. BRIG. E.M., Ana Ruiz Paz), which was the name in about 78 of the 90 such signatures. A mixed-case abbreviation counts as a title only if it is on a list, so Ma. (María) and Paz. Conste don't. Capitals keep the shape test.

A "Rúbrica" nothing cuts is counted by reason in meta.json. Each of these refusals was measured on the year before it was added:

• neither bold nor a title;
• an office signing without a name: one opening with an article (EL SECRETARIO DE SALUD, 389 signatures), or, in capitals, with DE/DEL or an office's head word that stands alone or before another office word (DIRECTORA GENERAL …, 52; CONSEJERO FRANCISCO RAMOS SILVA is kept);
• a date;
• a one-word cut.

The first draft's "what follows the last comma" and "whole clause" fallbacks were retired. They cut a name in 2 of 46 and about 5 of 60 distinct outputs.

The fetch caches one gzip of excerpts per day, so it resumes after an interruption and the cut can be re-read offline; robots.txt is read only once a day needs fetching. DOF_CUT_VERSION triggers a re-read and DOF_EXCERPT_VERSION a refetch, and the load check pins both.

The fetch refuses on any of these:

• a listing without all three editions;
• more than 5% of notes that state a size coming back blank (22 in 2025);
• more than 20% of notes stating a size of 0, the page-image notes (2,936 of 26,752, 11.0%);
• more than 5% of weekdays listing no note (7 of 261, all holidays);
• more than 10% of "Rúbrica"s left uncut.

A messageCode other than 200 is retried. Every 2025 listing was read again: all held the three editions and as many notes as cached.

Measured (2026-10-31)

• 33,565 signatures, 6,644 distinct names, from 35,305 "Rúbrica"s (cut version 6).
• Precision: of 200 random cuts checked by hand under cut version 5 (version 6 restores one capitalised name it refused), 199 were exactly a name and 1 a name behind a rank (VICEALMIRANTE …); none was not a name.
• Titled share: 65.4% of signatures open with a title.
  • Lic. 27.7%, Dr./Dra. 9.3%, Mtro./Mtra. 8.2%, C. 5.1%, Ing. 3.6%.
  • Spelled-out Licenciado/Licenciada 2.9%, and multi-period acronym degrees (C.P., L.C.P., M.A.P. …) 2.9%.
• Office glued with no comma: 45.5% of signatures are stacked, 45.3% under their office in the block above, and another 1.3% follow it inline with no punctuation.
• Readings: parse() reads the first word of a titled signature as a title in 82.1%; parser_for(locales.ES) does so in 86.8%. The misses are a leading C. (1,708 signatures), multi-period acronym degrees (988; their one-period spellings, LCP., already read as titles) and Maestro/Maestra (85). Issue drafts are with the session, not filed.

Checks

• uv run pytest, uv run mypy and uv run ruff check all clean.
• tests/v2/test_local_dof.py: 70 offline tests; each guard added in review fails against the module before it, with invented names and a fake urlopen.
• The new tests also pass on 3.15.
• One real fetch of the full year, and snapshot.py --local dof-signatures recorded and matching.
