   - THE COST, accepted by Derek on 2026-10-27: `FISH, ROYAL SR` reads given 'FISH' and no family, `sr` being a title as well as a suffix, so `ROYAL SR` is a title run with a head and H1 reads the word before the comma as the given name; one FEC name. A phrase with nothing behind it still names its last word (`Princess Royal` → title 'Princess', given 'Royal'), H4's reading of an input that is all vocabulary.
   - MEASURED (2026-10-27, against master `598167f4`, which holds the queen batch, py3.11, `uv run python tools/differential/measure.py --base <checkout>`, 16 steps). Fields: fec-individuals 49, 47 fixes, nearly every one `AA, ROYAL…`, where the queen head read title 'ROYAL' and no given name, 1 broken (above) and 1 input that names one person twice; jrc-names 6 spellings, `Princess Royal Anne`'s and a `consort marquise of X`; PSC and orcid-researchers agreement no record moved (ORCID 1,831,533 scored). Reports only: orcid-researchers 548 (`prince` 329, `princess` 103, `king` 70, `queen` 24, `royal` 15, a few behind `Dr.` or `Prof.`), PSC 310 records (`prince` 119, `princess` 58, `king` 49, `queen` 13, the rest `royal` and salutation forms), jrc-names 154 spellings, ctgov-officials 17, nepal-candidates 3, the committed corpora 13; tse-donors, tw-donors and ukec-individuals none; spelling pairs jrc-names 0 now alike and 1 apart; CLDR and GND agreement do not move. A v1 `Constants().titles` keeps all four royal titles, and `royal` and `consort` reach it as titles with no edit.

+- **2026-10-28 #913, `chancellor`, AND `judge` KEPT A TITLE (Derek) — THE LAST 2.8 TITLE BATCH: ONE TITLE BORNE AS A GIVEN NAME, AND THE PHRASES THAT KEEP JUDICIAL AND ACADEMIC TITLES WHOLE.** `judge` and `chancellor` were proposed together; Derek shipped `chancellor` alone and kept `judge` a title on 2026-10-28. `chancellor` gains a dated `given` reading and is a title only inside a title phrase: `Chancellor Smith`, `Mr Chancellor Smith` and `Smith, Chancellor` read given 'Chancellor', where 1.4.0 through 2.7.0 read the title. Before a family comma H6 no longer peels it (`Chancellor Case, Nancy` → family 'Chancellor Case', 1.4.0's reading). The phrases keep it: a modifier (`Vice Chancellor`, `Associate Chancellor`), `of` (`Chancellor of the Exchequer`), and `attaches` data added here for the phrases a modifier does not reach: `lord` attaches to `chancellor` and `justice` and `lady` to `justice` (`Lord Chancellor`, `Lord Justice`, `Lady Justice`), `deputy` to the office kind as `chief` does (`Deputy Chancellor`, `Deputy Judge`), `pro` to `chancellor` (`Pro Chancellor`), and `magistrate` to `judge` (`Magistrate Judge`, the US federal office, which with `judge` moved had lost its second word). `Lord Justice Leveson` and `Lady Justice Arden` now read the one title, where 1.4.0, which listed no `justice`, through 2.7.0, where it is contested (phase 2i), read title 'Lord', given 'Justice'. Since `Vice Chancellor` and `Lord Chancellor` are listed phrases, a bare `Chancellor` opening a name reports `title-or-name`, as `Dean Smith` does. Phrases that read the same on master and stay out of scope: `Circuit Judge`, `Probate Judge`, `His Honour Judge` and the hyphenated `Vice-Chancellor`.
+  - `judge` KEPT A TITLE, its evidence recorded in the note on its title reading so a later batch meets it: given US SSA 3,826 births (all male), Wikidata 7, nam_dict band 1 in the U.S.A.; family Census 10,453 (rank 3,414), Wikidata 133; in PSC 0 filers put it in the forename box and 0 in the title box. Measured as a contested title against master `f207e4f1`, it broke 13 FEC records, every one a judge filing `FAMILY, JUDGE GIVEN` (9) or `FAMILY, JUDGE` alone (4), and 2 jrc-names spellings of news text before a surname, against 2 fixes in all the local corpora (one ORCID and one PSC filer whose given name it is). The `TEST_NAMES` judges (`Judge James M. Moody`) and every example that uses `judge` as an ordinary surname in TITLES (the H section's Background, rules/H5, rules/H6 and rules/H7) keep it.
+  - THE COUNTS for `chancellor`, recorded on the word (`uv run python tools/name_usage.py chancellor`, 2026-10-28): given US SSA 2,648 births (2,643 male), Wikidata 13 (United States 3); family Census 4,147 (rank 7,974), Wikidata 77 (United Kingdom 11, United States 8).
+  - THE COST, accepted by Derek on 2026-10-28: a chancellor written with the bare title reads it as the given name (`Chancellor Merkel` → given 'Chancellor', family 'Merkel', where 1.4.0 through 2.7.0 read title 'Chancellor'), so does one alone after a full name and a comma (`John Smith, Chancellor` reverses to given 'Chancellor', family 'John Smith', the role-word class `John Smith, Dean` accepted), and a bare first-word `Chancellor` reports `title-or-name`.
+  - WORKED EXAMPLES MOVED. The v1 tests that add a custom title and parse it (`tests/test_constants.py`, `tests/test_python_api.py`) add `bursar`, in no default set, where they added `chancellor`, which v1's `Constants().titles` still holds; rules/H9 gains the `Lord Chancellor` and `Chancellor Smith` examples.
+  - MEASURED (2026-10-28, against master `f207e4f1`, py3.11, `uv run python tools/differential/measure.py --base <checkout>`, 16 steps). fec-individuals 10, all fixes: 4 `AA, CHANCELLOR` alone, which had read no given name, 1 `AA, CHANCELLOR A.`, 2 `AA, CHANCELLOR MR.`, and 3 with a two-word surname opening with the word before the comma, which had read it as the title; jrc-names 5 spellings, 3 fixed (`Lord Justice` and `Lady Justice` before a surname) and 2 broken, spellings of one head of government written with the bare title, now reporting `title-or-name`; ctgov-officials 1 fix (a `Deputy` and an office title after a comma, now one title through `deputy`'s attaches); orcid-researchers, psc-individuals, nepal-candidates, tse-donors, tw-donors and ukec-individuals none; ORCID (1,831,533 scored) and PSC (1,039,145 scored) agreement do not move; spelling pairs jrc-names 0 now alike and 0 apart; CLDR and GND agreement do not move. The committed corpora move by `Chancellor Jane Smith` (given 'Chancellor') beside the batch's rule examples. A v1 `Constants().titles` keeps `chancellor` and `judge` with no edit, and `c.titles.remove('chancellor')` turns every title reading of it off (the v1 title list entry above).

A list entry that is no kind must be a word with a title reading (a build check, its mutation in tests/v2/test_vocab.py). `major` attaches to `general` and `sergeant` and `sgt` to `major`. `grace` (style) and `marshal` (military, its #606 exclusion replaced) carry dated `given` readings.

The measurement is decisions/H9's entry of this date.
 - **2026-10-27 #913, royal title phrases (Derek) — `king`, `queen`, `prince` and `princess` CARRY `attaches`, `consort` IS A NEW MODIFIER AND `royal` HAS A DATED `given` READING.** `king` and `prince` attach to `consort`, `queen` to `consort` and `mother`, `princess` to `consort` and `royal`; `consort` (no bearers found) and `royal` address by the given name, so `Queen Consort Camilla` and `Princess Royal Anne` read the phrase as the title and the given name behind it. `royal`'s given reading keeps `BALES, ROYAL` the listing form's given name. The bare royal words now report `title-or-name`, a listed phrase holding them, accepted by Derek on 2026-10-27. The measurement and the rule change are decisions/H9's entry of this date.
 - **2026-10-27 #913, `queen` (Derek) — A #913 TITLE BATCH: `queen` has a dated `given` reading**, US SSA 16,123 births and Census rank 1,945 as a surname, so it is a title only inside a title phrase. `Queen Latifah`, `Ms Queen Smith` and `Smith, Queen` read given 'Queen' and the word behind it as the family; a monarch written with the bare title does too (`Queen Elizabeth II`), the class accepted for `king`, accepted by Derek on 2026-10-27. `Her Majesty Queen Elizabeth` and `Queen of England` keep the title. `Mary II, Dame` replaces `Elizabeth II, Queen` as rules/H1's example.

A chancellor written with the bare title reads it as a first name too (``Chancellor Merkel``), where a modifier, ``of`` or ``Lord`` keeps it (``Vice Chancellor Jane Smith``, ``Chancellor of the Exchequer``, ``Lord Chancellor John Smith``), and so do ``Deputy`` and ``Pro``. Since a listed title phrase holds it, a bare ``Chancellor`` opening a name reports a ``title-or-name`` ambiguity. ``Lord Justice Leveson`` and ``Lady Justice Arden`` give title ``Lord Justice`` and ``Lady Justice``, where 1.4.0 through 2.7.0 gave title ``Lord``, first ``Justice``. :issue:`913`
     - **Read the royal title phrases Queen Mother, King Consort, Queen Consort, Prince Consort, Princess Consort and Princess Royal as one title.** ``Prince Consort Albert`` gives title ``Prince Consort``, first ``Albert``, where 2.7.0 gave first ``Prince``, middle ``Consort``, last ``Albert``, and 1.4.0 title ``Prince``, first ``Consort``; ``Princess Royal Anne`` gives first ``Anne``. ``Royal`` after a family comma is the first name (``Bales, Royal`` gives first ``Royal``, where 1.4.0 through 2.7.0 gave title ``Royal``). Since a listed title phrase holds them, a bare ``King``, ``Queen``, ``Prince``, ``Princess`` or ``Royal`` opening a name now reports a ``title-or-name`` ambiguity, as ``Dean Smith`` does (``Prince Fielder``, ``Dr. King``). :issue:`913`
     - **Fix the given name Queen reading as a title.** ``Queen Latifah`` and ``Ms Queen Smith`` give first ``Queen``, where 1.4.0 through 2.7.0 gave title ``Queen`` and ``Ms Queen``; ``Smith, Queen`` reads the same. A monarch written with the bare title reads it as a first name too (``Queen Elizabeth II`` and ``Elizabeth II, Queen`` give first ``Queen``, last ``Elizabeth``), where a style keeps it (``Her Majesty Queen Elizabeth``), and so does ``of`` (``Queen of England``). :issue:`913`
     - **Fix the given names Deacon, Burgess and Ranger reading as titles.** ``Deacon Jones``, ``Burgess Meredith`` and ``Ranger Smith`` give first ``Deacon``, ``Burgess`` and ``Ranger``, where 1.4.0 through 2.7.0 gave title ``Deacon``, ``Burgess`` and ``Ranger``; ``Smith, Deacon`` reads the same. A cleric written with the bare title, or behind a salutation or ``Rev.``, reads it as a first name too (``The Rev. Deacon John Smith`` gives first ``Deacon``), where ``of`` keeps it (``Deacon of the Church Jane Smith``). ``Burgess Meredith`` reports a ``title-or-name`` ambiguity, since ``Chief Burgess`` is a title phrase. :issue:`913`
