Tracks the headroom #000046 (closed) left: the 6 over-grounds still
in falsification-hard-v1.jsonl (4 HYBRID_ENTITY where the
entity-proximity strategy matches a shared proper noun while the
answer's other salient term is wrong; 2 STRICT_PARAPHRASE where the
false claim recombines source tokens into a different true statement —
"Mercury is the largest" — and lexical token-coverage can't tell
recombination from grounding) + the 8 mis-segments in
formulate-hard-v1.jsonl (line/bullet-only parse_pointer_claims merges
multi-claim lines / splits wrapped bullets).
Options + recommended order: 2.1 verify_quotes entity
salient-token-disagreement gate (the direct analogue of #000046's
numeric gate — narrow, lexical, bench-safe; catches the 4
HYBRID_ENTITY) → 2.4 parse_pointer_claims sentence/clause
segmentation (closes the Formulate pack) → 2.2 sequence-aware
paraphrase match (conservative threshold; catches the 2
recombinations); defer 2.3 mini-NLI (heavier; only if 2.1+2.2 leave a
residue worth a model dep). Each landing bench-gated — verify_quotes
changes run `make bench-qa` before/after, parse_pointer_claims changes
run the Formulate fixtures + a QA smoke. Doc-only proposal; no code in
this ticket.
