Highest-risk axis of the ADR-0131.G capability iteration: within-
sentence multi-clause composition. Four extractors land in the
candidate-emitting parser; no graph-side or solver changes.
Parser extension (generate/math_candidate_parser.py)
- _conj_subject_each_candidates: '<A> and [his/her/their <kin>] <B>
each <verb> <N> <unit>' → 2 CandidateInitial (one per actor).
- _conj_object_candidates: '<E> has <N1> <unit1> and <N2> <unit2>' →
2 CandidateInitial for the same entity; same-unit conjuncts refuse
(would silently collide under solver overwrite-on-collision).
- _embedded_quantifier_candidates: '<E> has <N> <container> with <M>
<unit> in each [<container>]' → 1 derived CandidateInitial
(value=N*M).
- _embedded_quantifier_candidates (conj branch): '... <N1> <C> with
<M1> <U> in each ... and <N2> <C> with <M2> <U> in each ...' → 1
SUM CandidateInitial (value=N1*M1+N2*M2); mixed-unit refuses.
- CandidateInitial anchor whitelist widened to include
saved/earned/got/received/bought/made/paid (and inflections) —
narrow widening needed for the conjoined-subject-each shape.
Closed-set discipline
- Distributive 'each' only — 'each ... together/altogether' refuses.
- Two-way conjunction only — 3-way refuses by non-match.
- Cross-sentence coreference stays refused (within-sentence axis).
- Ambiguous 'each' scope refuses (container2 must agree).
Curated axis lane (32 cases)
- evals/math_capability_axes/G4_multi_clause/v1/cases.jsonl:
conj_subject_each ×6, conj_object ×6, embedded_quantifier ×6,
conj_embedded ×6, refusal ×8.
- evals/math_capability_axes/G4_multi_clause/v1/runner.py +
report.json: deterministic; wrong==0 gate; byte-equal across runs.
Tests (26 new)
- tests/test_adr_0131_G4_multi_clause.py: per-shape emission,
refusal probes (parametric), distributive-only policy,
cross-sentence refusal, runner byte-equality, GSM8K-probe gate.
GSM8K-probe gate (chosen: multi-clause refusals ↓)
- evals/gsm8k_math/train_sample/v1/report.json (candidate-graph
probe): multi-clause statement-refusal count 2 → 1. Case 0042
('Ella has 4 bags with 20 apples in each bag and six bags with 25
apples in each bag.') moves from statement-clause refusal to
question-layer refusal. Case 0026 ('Aaron and his brother Carson
each saved up $40') stays refused on the '$' value slot
(deferred to G.3 numeric-literals axis).
- evals/gsm8k_math/train_sample/v1/train_sample_coverage_report.json
(legacy probe): refreshed, byte-identical (legacy parser
untouched).
B3 + candidate-graph + GSM8K probe lanes all pass (95/95
regression). wrong==0 preserved everywhere — load-bearing for the
highest-risk axis.
