 **Sweep the forms a change can reach: comma shapes, then `name_order`.** No comma, a FULL name before the comma, a ONE-WORD name before the comma and NOTHING before the comma are four paths, and the last two are the misses — #429, #430 and #432 are all the one-word path disagreeing with the full-name path on inputs the full-name path reads correctly, and #613's PR review found `, PhD` and `, Jr.` (an empty surname field, as CSV data writes it) read as given and title by a decision that returned early on an empty head, after two review rounds whose every grid had a name before the comma. Put an empty head and a nickname-only head (`(Bob), PhD`) in every comma grid. Count the one-word path the way C3 counts, which is neither tokens nor pieces: a particle run and the one word it attaches to are one word (#575), a connective join and a bound given-name pair count as their words (#613, so `Ortega y Gasset, Dr.` is a whole name), and a suffix beside the surname counts as no name word at all. #603's review found the suffix half (`Vega y Lopez Jr., PhD Jones` lost its family where `Vega y Lopez, PhD Jones` kept it); #613 then reversed the connective half, and both now read given 'Vega', middle 'y', family 'Lopez' — so test a particle surname, a connective surname and a surname with a suffix, each before a comma. For orders the sweep already exists (`tests/v2/test_cases.py` runs every row under all three) but carries one assertion, R2's family partition, so it checks nothing a new change moves; coverage there has been vacuous before (PR #394's review found the suite passed with `name_order` discarded from grouping). Parse your change's names in each comma shape and each order, and read the ones you did not predict. And read a generated grid's moves by SHAPE, not by corpus membership: #614's first design passed the suite, the five gates and a fingerprint of every corpus name, because its grid moves were sorted into 'corpus name moved' and 'garbage', and the review found the moves that mattered among the 'garbage' -- a bare salutation (`Mr. and Mrs.` lost its connective to the family name) and a name with one trailing word (`Freiherr von Berg X.Y.Z.`). Pull out the head-plus-one-word slice of the grid and a salutation with nothing after it, and read every move there. Two more were the second review's (#614): no grid put TWO words that are both a title and a particle at the head (`Freiherr St van Berg MA`, where an index into the pieces was applied to a merged view of them -- `TITLES ∩ particles_ambiguous` is `{freiherr, st}`, so put both in every head list, each in its bare and its period-marked spelling -- #637's grid had `St` and `Freiherr` alone and missed that `St.` and `Freiherr.` are declined by the bound join and then attached by P6), and the grids compared ambiguity KINDS, so a report telling the caller the wrong field (`Freiherr von Berg Ma`, 'read as a given name' of a word in the family) passed every pin. #701's review added one: put a title/suffix dual (`Ms`, `Sr.`, `Cpl`) SECOND in a title run, behind an ordinary title. A stop that asks only "is this word suffix vocabulary" passes every row that opens with the dual and fails `Rev. Sr. Smith, Mary`; it was found by comparing `T Smith, John` against `T John Smith` over every title word, and a comma-versus-comma-less comparison is the cheap check for any rule that moves a word between the two slots. Compare each report's `detail` against the field its tokens land in -- since #626 `test_a_report_names_the_field_its_word_lands_in` (tests/v2/test_cases.py) does it over every non-locale case row under all three orders (a row carrying its own policy only as declared), for the phrasings its `_FIELD_CLAIMS` lists -- so a row with the shape is the test only where the report's wording is listed: a new emitter's wording goes in that list, and segment's report on a part past the second comma names no field (#629). #626's own first grid then missed an emitter for want of one comma shape (`, Ma Dr.`: an empty head, an ambiguous word, a trailing title, which H1 moves to the family): a trailing title belongs in every empty-head comma grid too. And #620's: an exclusion list in code being replaced is a set of rules, not noise -- #614's merged copy excluded every word the trailing read weighs from its units, the first #620 prototype dropped the list as a symptom of the copy, and its review found the list had been keeping positional counting's rule that a member in front counts as a word (`Freiherr von Berg MA X.Y.Z.` lost its suffix). Before deleting one, mutate each entry out and read what moves. The converse holds for replacing a hand copy WITH the shared predicate: it is a behavior change wherever the two disagreed, and #735's /simplify shipped one as "no reading moves" because the suite and the snapshot were its only check (`St Sir de Mesnil` family-first, a token test replaced by P1's piece test); diff the two predicates' answers over a grid before calling the swap a refactor.
 
-**Then sweep the spellings: a class reached by vocabulary is also reached by SHAPE.** A test that uses only the listed spelling of a word class walks only the vocabulary path, and the shape path is a separate branch that can be missing while every test passes. Roman numerals are the sharpest case: `ii`, `iii` and `iv` are suffix vocabulary; `i` and `v` are vocabulary too but initial-shaped, so `is_suffix_piece` vetoes them and only the numeral fork reads them; and `vi` through `x` are in no list at all, read by the fork's shape test alone (checked 2026-10-04 against `Lexicon.default()`) -- which stops at `x`: `_vocab._ROMAN` matches I to X, so `John Smith XI` reads `XI` as a name word (re-checked 2026-10-07, #614's /simplify, which found a docstring claiming "any length"). And the fork counts a ONE-letter numeral besides, since #718 (rules/S10): it is the suffix only where the name has a word to spare, so `John V` and `John Smith V` take different branches of one fork, a one-case name being counted like capitals whatever the letter -- since #721 a one-case one-letter numeral carries the `initial` tag its capital does, and since #723 every one-case bare letter does (rules/T4), and a bare letter in front of the numeral is initial-shaped as its capital is, so `john v` reads as `JOHN V` does over `test_a_one_case_name_reads_as_its_capitals`'s grid (comma shapes, orders, a maiden clause, a particle chain, a bare letter in front, a trailing title, a non-ASCII letter in front: 315 of its then 1,872 pairs disagreed at 2bfa9533, before #721, and none after). Its first version claimed "every shape" with no bare letter in front and no trailing title in the grid, and #721's reviews found both broken; a grid's claim is the grid -- put a head-plus-numeral row beside every words-to-spare row. So a change that handles `V` and `III` can still miss `VI` — #610 found exactly that, the maiden take's candidate loop admitting a shape-only numeral in one position where the peel reads it in two (`Jane Doe nee Smith VI Prof.` kept maiden `Smith VI` while `V` and `III` worked). #656's sweep found the same class from the other side: C12 takes the word ending the name before a comma as EVIDENCE, and its first draft asked the suffix-word tag, so `John Smith VI, AD` missed the rule `III` reached, and then counted the whole part, so `Smith VI, AD` fired with `VI` as its own name word and `Smith V, AD` with a `V` that S10 reads as the family. A rule that weighs a numeral as a generation must ask the predicate that READS it as one (the trailing fork and its words-to-spare count), not the vocabulary that lists some of its spellings. The same split runs through the credentials (`MA` listed, `X.Y.Z.` by the dotted shape, `XYZ` by the caps shape, and `Ph. D.` merged by group into one flagged piece the peel's walk never holds -- #603 found #602's run-start predicate refusing it too, so `Smith, John Ph. D. Jones` kept middle 'Jones' where `Smith, John PhD Jones` read suffix 'PhD Jones') and the titles (`Prof.` period-marked and read at the end of a name, `Prof` bare and a name word there). When a change touches a word class, test one spelling from each path. The same holds for a separator's SPACING: a comma (or any punctuation) can stand alone, glue to the word before it or glue to the word after, and each is a different token stream. #653's first fix swept `(née, Jones)` and missed `(née , Jones)`, where the kept comma became a word after the marker and M3 read the clause as maiden ', Jones'; its review found it. Put all three spacings in any grid around a separator.

 **And the encoding: a letter class written `[^\W\d_]` or tested with `isalpha()` is blind to a combining mark.** Python's `\w` and `isalpha()` do not match Mn, so a letter written as base plus accent (NFD) ends a word early; the vocabulary path is immune because `_normalize` NFC-folds, the shape path is not. #652: `Dr. inž. Janez Novak` read `inž.` as the given name when the ž was decomposed, and `Janez Novak, ŽŠČ` reversed, in two families that share the blind spot — the letter-shape regexes (`period_abbreviation`, `_DOTTED`, `_CHUNKED`, `_PAIRED_INITIALS`), now spelled with `_vocab._LETTER` (a letter plus the general combining blocks; `test_regex_sync` compares the two `_MARKS` strings and pins `period_abbreviation` against config's copy), and the caps predicates, which NFC-compose a non-ASCII word before `isalpha()` (`is_caps_word`, behind C-level `isalpha()`/`is_normalized` tests, so already-composed text pays no frame — measured 2026-10-12, `Smith, José` was 193 frames before and after; the first version called it for every non-ASCII word and cost one frame each, and no guard saw it because the reference name is ASCII). A width test must count letters, not code points (`composed_len`): admitting a decomposed word to the caps set put `John Smith, MÁ` on the pair exception's wrong side, and the review's grid found it where the rows (all three letters long) did not — put a two-letter word in every caps grid. The initial shape (`_INITIAL`, `\w\.`, v1-verbatim and public) is not widened but asked of the COMPOSED word, in `is_initial_shaped` and in `_render`'s two copies; and the single-letter connective tests count composed letters, since a decomposed `й` is two code points (#665, where `É. y É. Smith` and `John й Smith` read differently decomposed). Compose the WHOLE predicate, not one half: `is_initial` is a shape ANDed with the #320 script veto, and composing the shape alone made a decomposed `씨.` an initial, since decomposed hangul is conjoining jamo outside every script range (#665's first version; `in_initialless_script` composes too now). Not covered, deliberately: the marks only some scripts write (Indic vowel signs, Arabic and Hebrew points; rules/H2's Accepted clause). The guard is `test_a_decomposed_name_renders_as_its_composed_twin` over the CLDR corpus plus `test_a_decomposed_abbreviation_reads_as_its_composed_twin` (rows × three orders × EVERYWHERE); the corpus guard reaches a shape only if some corpus name does, which is how the caps shape was missed until review, so when adding a shape rule add a row there. Four of #652's rows and two of #665's pass with every fix reverted (measured) and are parity pins, and the test compares ambiguity kinds and `initials()` too, since #665's `John й Smith` differed in its report; `_DOTTED` has no observable input and is pinned by a direct call.

   THE HONORIFICS, found by the design-docs review: the tag reaches every suffix word, so `Tenzin Gyatso Rinpoche, AD` reads suffix 'Rinpoche, AD' where the parent read given 'AD'. Kept as stated rather than narrowed to generations: an honorific written after the name stands in the same place a generation does, and no vocabulary set separates the generations from the rest. Dotted paired initials were the review's other find: `Smith Jones Jr., J.A.` read suffix 'Jr., J.A.', since the veto asked only the `initial` tag; `is_paired_initials` joins it, as C5 keeps such a pair the given name.
   DECLINED: adding `mbchb` to SUFFIX_ACRONYMS, approved in the session before the rule was measured. `MBChB` ends in a capital, so it is not written as a name and the rule reads `van den Berg jnr., MBChB PhD` without it; a vocabulary member would also reach `Smith, MBChB`, which nothing here measured.
   Measured 2026-10-18 on this change against its parent: five corpus names move, every one a CLDR rendering of the shape and each to the agreeing reading on family, given, suffix and title where CLDR states them (`Sig. Fabio Massimo Carlo Alberto Martini II, AD` in both orders, `prof. dr. Ada Cornelia César Martín von Brühl Jr, univ. bacc`, `Prof. dr. Cornelia Margarita Sofia Aletta van den Berg jnr., MBChB PhD`, `Skeggjason Hr. Geir Jón Magnús Brynjar yngri, þingmaður`); the last still disagrees on its given names, CLDR's `Geir Jón Magnús Brynjar` against `Hr. Geir Jón Magnús Brynjar`, a title inside a surname-first name, which is not this rule. No other corpus name moves, read off `snapshot.py`'s report. The issue's comment counted 25 disagreements of the shape on 2026-10-13; the `Jr, MP` renderings among them read correctly on the parent already, MP being listed.
+- 2026-10-19 (Derek), PR #735's altitude review — A TITLE RUN A CONNECTIVE JOINS (P3, C7) READS AS A TITLE IN THE PART, AS A SINGLE TITLE WORD DOES. The rule's title test was a hand copy of C8's that asked only a one-word piece's vocabulary tags, so a joined title (piece tag `title`) fell to the suffix side: `John Smith Jr., Mr. and Mrs. AD` read suffix 'Jr., Mr. and Mrs. AD', while `John Smith, PhD Mr. and Mrs. AD` (C8) and `John Smith Jr., Mr. and Mrs.` (no credential) both read title 'Mr. and Mrs.'. `_behind_a_generation` now asks C8's predicates in C8's order, `not is_suffix_piece` then `is_title_piece`. They agree with the copy on every one-word piece, a lone dual still reading as the suffix (`John Smith Jr., Sr. AD`); they differ in principle only on an `initial`-tagged dual, which the rule's own veto turns away first. A dual INSIDE a joined title now reads as part of the title (`John Smith Jr., AD Sr. and Mr.` → title 'Sr. and Mr.'), as C8 reads it (`John Smith, PhD Sr. and Mr.`), found by the PR's code review.

Sr.`, `AD Dr.`, `Dr.`, `Sir`, `PhD`, `AD` after it × the three orders: 192 of 768 readings move, exactly the eight parts where a joined title stands beside an unlisted credential, under every name and order, each from suffix to title. A joined title beside a listed credential (`Prof. and Dr. MD`) or with none (`Secretary of State`) already read as a title, the rule not being reached. No ambiguity kind or `initials()` moves, and no corpus name moves (the snapshot gains only the rule's new examples).
