Should an unlisted abbreviation after a full name and a comma read as a post-nominal, as in Jan Novák, DiS.? #969

Found by the cz-candidates local corpus (#963), fetched 2026-10-30 (170,181 records). Names are invented.

Today

• Jan Novák, DiS. → title DiS., given Jan, family Novák. Every unlisted period-marked word does the same: Jan Novák, Xyz. → title Xyz..
• With a title in front it joins that title: Bc. Jan Novák, DiS. → title Bc. DiS..
• locales.CS reads them the same way.

DiS. (diplomovaný specialista) is a Czech/Slovak tertiary diploma, written after the name.

Mechanism: the part after the comma is not all suffix words, so rules/C1 reads it as the listing form; rules/H2 then reads the unlisted abbreviation heading the given part as a title; and rules/C8 reads the part before the comma as the whole name.

Size

• 3,248 records hold dis in the box after the name (re.search(r"\bdis\b", box.replace(".", "").casefold())). In 3,232 of them the parse reads DiS. as a title (its title holds dis by the same test).
• The same shape hits dipl. um. (27, plus 9 spaced variants), Dr. (10), ArtD. (3), IEn. (3) and, under the default only, DrSc. (12).
• The box after the name agrees for 56.0% of the 7,687 that are filled; about 96% without DiS..

Options (none chosen)

• (a) Vocabulary: list DiS. as a credential (in cs.toml/sk.toml, or mul.toml), after checking its name readings with tools/name_usage.py dis. Fixes DiS. only.
• (b) Structure: after a comma behind two or more name words, read a part that is only an unlisted abbreviation as a post-nominal rather than a listing-form given part. This cuts against rules/H2's family-comma reading (Smith, Xyz. → title, as in 1.4.0) and rules/C3's word count, and needs the comma-shape sweep.

Open: would (b) move ctgov-officials or psc-individuals?
