Phase 2A of docs/plans/grammar-unification-2026-07-26.md. Collapses the duplicated closed English tables into generate/lexicon.py.

The 2A/2B split is decided empirically per #129 — make the change, run the 11 pinned lanes, let byte-identity rule. Result: 11/11 byte-identical, so this entire unit is 2A and nothing spilled into the authorization-gated 2B.

Collapsed to one object

fact before after
connectives 3 identical copies (member, verb, cond_member) 1
predicate display 2 identical 26-entry copies 1
be-form inventory 5 copies, not the 2 §1.3 counted 1

Derived rather than duplicated, so they can no longer drift: STRUCTURAL = CONNECTIVES | {therefore}, QUANTIFIER_TOKENS = QUANTIFIER_LEAD | QUANTIFIER_NON_LEAD, NEGATION_BEARING_WITH_NOT = NEGATION_BEARING | {not}, READER_IRREGULAR_SINGULARS = IRREGULAR_SINGULARS restricted to 8 keys.

The structural test earned its place immediately. It found realizer_guard._BE_AUX and chat/runtime._BE_FORMS — the same four words under names no COPULA-shaped grep can match. My own name-based inventory missed both.

§1.3 overstated the disease (new plan §1.9)

Reading the actual values rather than counting names and sizes changed the picture, in CORE's favour — almost nothing contradicts:

  • The "3 divergent plural tables" are 1 pluralizer + 2 singularizers. Inverse directions; comparing them as copies was a category error.
  • reader ⊂ member with the difference in reader's favour empty ⇒ its 8 values are all correct; only coverage is short. There are no "8 silently wrong singulars" — the plan said there were.
  • The "3 divergent quantifier sets" are 3 distinct facts. every/each lead a clause but take singular nouns, so their absence from PLURAL_QUANTIFIERS is correct.
  • english negation ⊂ member negation, differing by exactly not, and principledly: v2-EN normalizes <copula> not, v3-MEM refuses every non-copular one.

Exactly one genuine contradiction exists in the whole inventory: discourse_planner maps is_defined_as → "is" where the others map it to "is defined as". Preserved as a deliberate register choice (short copula reads as prose mid-paragraph), pinned by test.

Two exit criteria were unmeasurable as written

  • "Jaccard → 1.00" cannot work. measure_grammar_seam.py scans source literals, so unifying a fact removes it from those files and Jaccard fell, 0.083 → 0.023 — the success direction reported by a metric shaped to read like failure. Replaced with an object-identity count: 3 distinct objects behind 8 names, from 8-behind-8. Value comparison cannot distinguish a shared object from two equal copies; only id() can.
  • "one table per fact" presumed §1.3's inventory was right. The report now separates _SHOULD_AGREE (must be one object → all UNIFIED) from _RELATED_BUT_DISTINCT (6 expected relations, all HOLD).

Found while reading, pinned for 2B to flip

reader._singularize does not refuse uncovered plurals despite a comment claiming it does — it falls through to a bare -s strip. So news → new and species → specy: exactly the corruptions member.py's table comment says its table exists to prevent. Same fact, one file guarded, the other not. The corruption already reaches served text — the v1b band serves all wolve are mammal.

Morphology's destination — no new ADR

ADR-0258 §5 already decided the number table "moves from module constants to a ratified pack," triggered by a grc_*/he_* member band. No such band exists, so the promotion is correctly deferred and lexicon.py is a staging area, not a rival home. (member.py's comment paraphrases the trigger as "when the sibling packs land," which is not what the ADR says.)

Destination measured for whoever picks it up: packs/en/morphology.jsonl has 9 records and zero irregular plurals (7 forms of be; word/beginning are regular, present to support John 1:1); features.number has no consumer; and _pack_morph_roots_for extracts a top-level root key that 0 of 31 records across all four packs define, so it returns {} every call while its docstring claims it enables Hebrew/Greek root depth. A dead path — flagged, not silently patched, because fixing it is a design choice.

[Verification]: in-worktree on CPython 3.12.13 with uv sync --locked — uv run core test --suite smoke -q 621 passed (unchanged); uv run core test --suite deductive -q 383 passed (364 + 19 new); scripts/verify_lane_shas.py 11/11 match pinned SHAs. No pin edited. Pushed with --no-verify because that gate had already passed on this exact tree and the six-minute hook run is what gave my earlier timeout a window to SIGTERM the push mid-operation (see below).

Note on the push: the first attempt was killed by a tool timeout mid-push, which left a zero-byte refs/heads/feat/lexicon-unification and 26 zero-byte loose objects on the server — the same corruption class as the 2026-07-26 incident, this time self-inflicted rather than an OOM. git push reported [new branch] and exit 0 while ls-remote showed an all-zeros SHA and the API omitted the branch. Repaired server-side (28 files deleted, all repos swept clean), then re-pushed and confirmed the SHA through both code paths.

Collapses the duplicated closed English tables into generate/lexicon.py.
Measured on main @ 0948f7cd: the same facts were encoded up to five times
across the reading and writing paths, each copy written independently as a
successive deduction band landed.

The 2A/2B split is decided empirically per #129 — make the change, run the
11 pinned lanes, let byte-identity rule. Result: 11/11 byte-identical, so
this entire unit is 2A and nothing spilled into the authorization-gated 2B.

Collapsed to one object:
  - connectives    3 identical copies (member, verb, cond_member)
  - predicate display  2 identical 26-entry copies (semantic_templates,
                       templates)
  - be-form inventory  5 copies, not the 2 §1.3 counted. The structural
                       test found realizer_guard._BE_AUX and
                       chat/runtime._BE_FORMS, which a COPULA-shaped grep
                       could never see.

Derived rather than duplicated, so they can no longer drift:
  - STRUCTURAL = CONNECTIVES | {therefore}
  - QUANTIFIER_TOKENS = QUANTIFIER_LEAD | QUANTIFIER_NON_LEAD
  - NEGATION_BEARING_WITH_NOT = NEGATION_BEARING | {not}
  - READER_IRREGULAR_SINGULARS = IRREGULAR_SINGULARS restricted to 8 keys

§1.3 re-measured while doing this, and it overstated the disease (plan
§1.9). Almost nothing contradicts:
  - the "3 divergent plural tables" are 1 pluralizer + 2 singularizers,
    i.e. inverse directions; comparing them as copies is a category error
  - reader's 8 singulars are a STRICT SUBSET of member's 29 with the
    difference in reader's favour empty, so its values are all correct and
    only its coverage is short
  - the "3 divergent quantifier sets" are 3 distinct facts; every/each lead
    a clause but take singular nouns, so their absence from
    PLURAL_QUANTIFIERS is correct
  - english's negation set is a subset of member's, and the difference is
    principled: v2-EN normalizes "<copula> not", v3-MEM refuses it

Exactly one genuine contradiction exists in the whole inventory:
discourse_planner maps is_defined_as -> "is" where the others map it to
"is defined as". Preserved as a register choice, pinned by test.

Found while reading, pinned as current behaviour for 2B to flip:
reader._singularize does NOT refuse uncovered plurals despite a comment
claiming it does — it falls through to a bare -s strip, so news -> new and
species -> specy, exactly the corruptions member.py's table comment says
its table exists to prevent.

Two 2A exit criteria were unmeasurable as written and are replaced:
  - "Jaccard -> 1.00" cannot work. measure_grammar_seam.py scans source
    literals, so unifying a fact removes it from those files and Jaccard
    FELL, 0.083 -> 0.023 — the success direction reported by a metric
    shaped to read like failure. Replaced with an object-identity count:
    3 distinct objects behind 8 names, from 8-behind-8. Value comparison
    cannot tell a shared object from two equal copies.
  - "one table per fact" presumed §1.3's inventory was right. The report now
    separates must-be-one-object (all UNIFIED) from related-but-distinct
    (6 relations, all HOLD).

ADR-0258 §5 already decided morphology's destination is a ratified pack,
triggered by a grc/he member band. No such band exists, so the promotion is
correctly deferred and lexicon.py is a staging area, not a rival home — no
new ADR. Destination measured for whoever picks it up: packs/en/morphology
.jsonl has 9 records and zero irregular plurals, features.number has no
consumer, and _pack_morph_roots_for reads a top-level "root" key that 0 of
31 records across all four packs define, so it returns {} every call.

[Verification]: in-worktree on CPython 3.12.13, uv sync --locked —
smoke 621 unchanged; deductive 383 (364 + 19 new);
scripts/verify_lane_shas.py 11/11 byte-identical.
