-- 2026-10-04 (Derek), #603 (decided at group's head since #613, decisions/C1) — A CREDENTIAL OPENING THE PART AFTER THE COMMA MAKES IT THE POSTNOMINAL PART, WHATEVER FOLLOWS; AND A TITLE WORD PAST THE SECOND COMMA IS A TITLE. One word that is neither suffix nor title vocabulary used to flip the whole comma reading: `John Smith, PhD Jones` read family 'John Smith', given 'PhD', where `John Smith, MD FACS` and `Eric H. Holder, Jr. Attorney General` were already read as a name and its postnominals. Now the first suffix word of the part, with only titles in front of it, opens the part when it starts S2's run (`_pieces.starts_a_credential_run`, #602's own predicate, so the two runs cannot disagree about what starts one), and every word after it reads as that run reads: a title word as a title, any other as a suffix. The mechanism was the one #296 built for a part holding no name word, extended rather than added beside; where this entry had segment deciding it, #613 (decisions/C1) decides it once at group's head. Every word the opened part takes that would otherwise have made it the given part is reported (`suffix-or-name`), as #602's run reports what it absorbs.
+- 2026-10-04 (Derek), #603 (decided at group's head since #613, decisions/C1; its `John Smith, MD Jones` and `MD - PhD - FACS` readings superseded by #853, decisions/indic-honorifics, `MD` being no title there) — A CREDENTIAL OPENING THE PART AFTER THE COMMA MAKES IT THE POSTNOMINAL PART, WHATEVER FOLLOWS; AND A TITLE WORD PAST THE SECOND COMMA IS A TITLE. One word that is neither suffix nor title vocabulary used to flip the whole comma reading: `John Smith, PhD Jones` read family 'John Smith', given 'PhD', where `John Smith, MD FACS` and `Eric H. Holder, Jr. Attorney General` were already read as a name and its postnominals. Now the first suffix word of the part, with only titles in front of it, opens the part when it starts S2's run (`_pieces.starts_a_credential_run`, #602's own predicate, so the two runs cannot disagree about what starts one), and every word after it reads as that run reads: a title word as a title, any other as a suffix. The mechanism was the one #296 built for a part holding no name word, extended rather than added beside; where this entry had segment deciding it, #613 (decisions/C1) decides it once at group's head. Every word the opened part takes that would otherwise have made it the given part is reported (`suffix-or-name`), as #602's run reports what it absorbs.
   THE ONE-WORD PATH, DECIDED (Derek): the whole part is suffixes. `Doe, PhD Jones` reads family 'Doe', suffix 'PhD Jones', no given name, as `Smith, PhD` already reads. DECLINED: reading the credential as a suffix and the next name word as the given name (`Smith, PhD Jones` → given 'Jones'), proposed by analogy with a title at the head of the given part. Asked whether that is a real format, it is not -- nobody writes `Family, Credential Given` on purpose -- and the one realistic input it served, a misplaced generation (`Smith, Jr. John` for `Smith Jr., John`), is garbage in, garbage out. One reading for both comma paths was the deciding ground: the one-word path disagreeing with the full-name path is the shape #429, #430 and #432 each found. Accepted cost: `Smith, Jr. John` loses 'John' to the suffix, where 2.3 read given 'John' with 'Jr.' misfiled as a title.
   A TITLE/SUFFIX DUAL OPENS NOTHING (Derek). A word in both vocabularies (`md`, `ms`, `sr`, the ranks `lt`, `cpl` and the rest) is the listing form's title in front of a given name, `Smith, Ms Jane`, and a credential behind it opens nothing either (`Smith, Ms PhD Jones` keeps given 'PhD', as `Smith, MD PhD Ma` keeps given 'Ma' under #544). DECLINED after building it: a dual opening the part behind two or more words before the comma. Derek first chose it for `John Smith, MD Jones`; the reviews found what the count cannot see -- a surname of two words (`García Márquez, Ms Gabriela`, `Smith Jones, Sr. Maria`), a title in front of a one-word surname (`Dr. Smith, Ms Jane`, the count taking the title as a word), and spaced initials (`García Márquez, Ms G. J.`) each lost the given name -- and with the word explained (a dual is a word in both lists, decided by position), Derek chose that duals never open. So `John Smith, MD Jones` and the `MD - PhD - FACS` delimiter rows keep their 2.3 reading. An ambiguous-class member opens nothing either (`John Smith, Ma Jones` keeps given 'Ma'), nor does a suffix word S2's run start refuses (`John Smith, vd Jones`).
   STRICT MODE: the veto refuses an initial-shaped word the suffix READING, not the run. `Smith, PSM I.` under `lenient_comma_suffixes=False` reads suffix 'PSM I.' (2.3: given 'PSM', suffix 'I.'), reporting the absorbed 'I.', which matches #602's no-comma run (`John Smith PhD V.` reports; its given-part run does not, a disagreement #602 left and this does not touch).

Three commits of the approved #291/#296 bundle (spec 2026-07-30, plan 2026-08-01; see decisions/comma-suffix-arc), in the plan's order. (1) A comma followed only by titles fixed no family boundary, so the pre-comma name keeps its positional read: `John Smith, Mr.` reads given 'John', family 'Smith', title 'Mr.' where 2.0 had merged the family ('Bob Jones, author' moves with it at every baseline). "Nothing but titles" is title-shaped AND not suffix vocabulary — the plan's helper said only the first, and would have read `Smith, PhD Jr.` as the title run 'PhD Jr.' and `Smith, Mr. Jr.` as 'Mr. Jr.' (both master's suffix 'Jr.'; the gate and a measurement against master caught them). (2) The TITLES/suffix overlap audit and the ordering, one commit because each alone is wrong (the plan's F1): reading the credential run first would make `Smith, Dr.` a suffix while 'dr' was SUFFIX_WORDS residue, and the audit alone leaves `Smith, Jr.` a title by the period-abbreviation inference. The audit table's dispositions ship as approved — 'do', 'jr', 'junior', 'phd', 'se' out of TITLES; 'dr' and 'sra' out of the suffix sets; 'ms' and 'sa' into the ambiguous set — with ONE deviation on evidence the table did not have: 'md' keeps dual membership, because bare 'Md' before a name is the Bengali and South Asian Muslim abbreviation of Muhammad (#343/#345's corpus rows `Md Abdul Karim`, `Md. Abdul Karim`; the drop read the first as given 'Md', middle 'Abdul') while 'MD' after the name is the degree — position decides, as for 'sr'. The ordering is wider than the plan's lone piece: a post-comma part that is nothing but suffix pieces is the credential run, whole, which is what #325 needed (`Smith, Ph. D. Jr.` had put the split credential in the given name once a second suffix made it no longer lone — a 1.4.0 regression; v1 read suffix 'Ph. D.', title 'Jr.'). Vocabulary decides which words qualify and position breaks the tie for the genuine duals: `Smith, Sr.` is Senior where `Sr. Garcia` is Señor, `Smith, Esq.` is the postnominal where H2 still reads `Esq. Smith` as a title (H2 carries that as Accepted). `Smith, Dr. Jr.` keeps the 2.0 deviation's other case — a title, then the last piece as the suffix (v1 read first 'Jr.'; 2.0 through master suffix 'Jr.') — and `Smith, John Jr.` its given name. Consequences the audit carries, all measured and pinned: a leading 'PhD' or 'Jr' is a name word; `Do Quang Minh` reads given 'Do' with the particle-or-given fork, and `Dr. Do Van Johnson, MD` given 'Do', family 'Van Johnson' (the #367 rule for that name is replaced; TITLES ∩ ambiguous is {freiherr, st} now, which keeps the chained emitter reachable); a trailing bare 'Dr' is a name word, joining every other title-only word there (#316 is the open question); `田中さん, PhD` reads suffix 'さん, PhD'; the #100 prefix-join tests use 'lt', a genuine dual, as their token. #291 (multi-word credentials) is the bundle's fourth commit and its own PR.

 - 2026-08-23 (review of PR #428, four reviewers) (its `Smith, RN - CRNA` given 'RN' superseded by #603, decisions/C13; its unreported `Freiherr von Berg Ma, Mr.` superseded by #613, decisions/C1) — the repair's condition is "no name word", not "all titles": `John Smith, Mr. Jr.` (a title and a postnominal) had kept the merge the rationale argues against, and reads given 'John', family 'Smith', suffix 'Jr.' now. Its guard counts NAME pieces: the positional read peels a trailing suffix first, so `Smith Jr., Mr.` — two pieces, one name — read positionally lost its family (the code review); it keeps family 'Smith', suffix 'Jr.' at every baseline. The positional read records its ORDER, and post_rules' leading-piece scan keys on "assign records no order after a family comma" rather than on the structure, so P1's family-first fold reaches the pre-comma name as it does without the comma — `de Mesnil Jean, Dr.` under a family-first order had read family 'de' (the test review). The credential run does NOT step over a delimiter core the policy names (`Smith, RN - CRNA` reads given 'RN' under `extra_suffix_delimiters` as without it): the code review asked for it, a draft did it, and tests/test_suffixes.py's "the delimiter must not affect parsing at all" outside the suffix-comma form is v1 parity pinned on purpose — rules/C10 carries the limit as Accepted. A second deviation from the audit table: `ms` and `sa` do NOT join the ambiguous set — the gate is position-blind and the collision is not; gated, `John Smith, MS` lost its suffix-comma route and read title 'MS', and `Smith, Ms.` passed the gate on its one period and read as a credential anyway. Both are genuine duals, and position decides: `Smith, Ms.` reads suffix 'Ms.' (title at every baseline; rules/C8 carries it as Accepted, with `Smith, Ms. Jane` keeping the title) and `John Smith, MS` keeps suffix 'MS'. And the gate itself now means what S2 said (rules/S3 since 2026-10-19): an ambiguous acronym counts when written with ITS periods, one after each letter (`M.A.`, `J.D.`), not on any period — `Smith, Ed.` had become a credential on a name's trailing period, and `Jack Ma.` had read suffix 'Ma.' since 2.0 (S3 carries the boundary since 2026-10-19; 1.4.0 read family 'Ma.'). Two limits recorded rather than fixed: `田中さん, Dr.` keeps the honorific glued, joining master's `田中さん, Mr.` — the honorific peel runs in script_segment on the suffix-comma and no-comma structures, before group or assign can say the comma fixed nothing (C1 Accepted); and group's chain emitter still reports no PARTICLE_OR_GIVEN on the family-comma path, so `Freiherr von Berg Ma, Mr.` reads as its no-comma twin but without the report — group runs before assign decides which read applies, and plumbing a deferred report through the state is more than the shape is worth today.
 - 2026-10-04 (Derek), #603 — A credential opening the part after the comma makes it the postnominal part, whatever follows. The record moved to decisions/C13 with that clause (2026-10-19).
 - 2026-10-18 #728 — SPLIT FROM decisions/C1 with the rule. The entries above were written under decisions/C1 while this rule was part of rules/C1, and moved here unchanged but for the pointers the move broke, the measurement paragraphs, each cut to one line naming its population, counts, baseline and PR, and the superseded passages, each cut to its decision and what replaced it; where one says rules/C1 or C1, it means the rule as it then stood, which held this one.
