Part of #1115: its first slice. It covers the given names written short and the new reason for rules/H6. The title batches, the defaults for the pack-only degrees, the exclusions and the Diplom degrees come later.

What changes

Given names written short. Seven words get a given reading with same_as, so rules/H2's leading-abbreviation shape yields to them as it does to Chas. (#789):

Word	Full name	File
mohd, mhd	Muhammad	mul.toml (Malaysia, India, Indonesia, Syria)
muh, moh, moch	Muhammad	id.toml
ach	Achmad	id.toml
fco	Francisco	es.toml

Mohd. Shameem Khan    title 'Mohd.', given 'Shameem'  →  given 'Mohd.', middle 'Shameem'   (1.4.0 through 2.8.2 read the title)
Dr. Muh. Hamdan       title 'Dr. Muh.', no given    →  title 'Dr.', given 'Muh.'
Moch. Yunus, M.Kes.   family 'Moch. Yunus', given 'M.Kes.'  →  given 'Moch.', suffix 'M.Kes.'

Each word's ORCID box counts are on its entry. mo is left out. 45 corpus names write Mo. for Muhammad (42 of them Nepalese candidates), but bare Mo is mostly the Chinese and Korean name (ORCID family boxes 3,478, China 952). A given reading would make Reading.languages report a Mo Yan's given name as read in the file holding the word. Md. keeps its 2026-10-27 reading (decisions/indic-honorifics).

rules/H6 (a title before a family comma) keeps its vocabulary-only run, on a new reason. #710's reason was the Sta. Maria cost, and #725 removed it by making sta/sto saint particles, which the run already stops at. A scan of what a shape peel would reach (72 names on dd2650ef) finds the reason that remains. A period-marked word before a family comma is as often a given name written short (Md. Abu Shahin, FCPS, MD), a stray period on a name word (BEUMLER. WEAVER, CAROL) or a surname's head that is no particle (MT. PLEASANT, JANE) as it is a title. So titles get listed, and slips read wherever the rules put them. decisions/H6 records the measurements, and #710's caveat stands: H2's head shape has no particle stop.

Measured

uv run python tools/differential/config_diff.py diff --local all --committed --match '(?i)\b(mohd|muh|moh|mhd|moch|ach|fco)\b' '<the tree without the seven readings>' default, 2026-11-06 against 0a4233f1. 125 of the 3,089 matching names move:

• 122 from title to given
• 2 comma names that C4 now counts correctly
• 1 where a particle behind the given name starts the family (Mohd. Abu Bakar Siddique → family 'Abu Bakar Siddique'), the cost decisions/indic-honorifics accepts for Md Abu Sayed

A sweep of 16 shapes × 3 name orders for Mohd, Muh and Fco moved names only where H2's shape had fired (the head of the given part). Under the family-first orders the word is then placed by position, as Chas. is. Nothing moved in the trailing, bare or before-a-family-comma positions.

The committed snapshot gains one name (Mt. Pleasant, Jane, a new H6 boundary row) and moves none.

Review

The design-docs review ran all twelve axes and found six problems, all fixed in the second commit:

• the CLDR Excm. names predate Dr. Smith, John reads family Dr. Smith: a title before a family comma isn't peeled #701, so Dr. Smith, John reads family Dr. Smith: a title before a family comma isn't peeled #701's "every CLDR case is a listed title" never held (the Which abbreviations that open a name should the vocabulary list: Excm., Mohd., Mt.? #1115 issue body repeats the wrong Read the field and the comma from what stands beside it: H1 behind a comma (#720), C12 (#656) #735 attribution)
• Sta. Maria still stood as a reason in H6's Because
• the shipped-abbreviation lists in decisions/H2, vocabulary-model and rules/H2 were stale
• three counts were off

Test plan

• uv run pytest (39,051 passed) and uv run pytest -n0 -m serial
• uv run mypy, uv run ruff check
• uv run sphinx-build -b doctest docs and the html build
• Case rows in tests/v2/cases.py checked against an export of master; the release-log claim checked against the 1.4.0 and 2.8.2 wheels
