Proposed sub-ADR under ADR-0164 resolving Open question #3.
- Reviews existing _resolve_question_entity heuristic in
generate/math_candidate_parser.py: refuse-on-ambiguity is correct,
but flat-document whitelist scan misses recency, kinship entities,
group antecedents from conjunction, and names absent from the
closed name lists.
- Specifies EntityRegistry as a field on ProblemReadingState
(ADR-0164.3 companion): append-only entries with canonical name,
inferred gender + source, mention positions, and relational anchor
for kinship entities.
- Two refusal-first ambiguity rules: ambiguous_pronoun_referent (R1,
recency tiebreaker within RECENCY_GAP_MIN refuses) and
unresolved_pronoun (R2).
- Worked walk-through on five GSM8K train_sample cases (0001 Tina,
0010 Yun/Marion, 0027 Malcolm, 0017 Jason/Eric, 0033 Rachel + kin).
- Three policy-vs-heuristic disagreements (D1 Jason/Eric him; D2
Georgie he via single-salient back-fill; D3 Aaron/Carson they via
GROUP entry) all turn refusals into correct resolutions, plus one
counter-direction D4 where new policy is principled-conservative.
- Preserves wrong = 0 by construction at every branch.
