Extends the #000046 hard tier to the Formulate sub-battery.
bench/fixtures/5f/formulate-hard-v1.jsonl — 12 prose inputs that
arborist.qa.parse_claims.parse_pointer_claims SHOULD segment into a
particular claim lattice (recorded in expected_lattice). The parser
is line/bullet-based — one line ⇒ one claim, [E#] tokens attach to
it — so 8 of 12 it mis-segments: merges and-/semicolon-/dash-joined
or (1)(2)-enumerated multi-claim lines into one claim with all the
pointers, or splits a wrapped bullet into two. Those 8 fail at HEAD
on claim-count mismatch; the other 4 are well-formed bullet/numbered
lists / single claims the parser handles right. Rate at HEAD = 4/12
= 0.333, stable (parse_pointer_claims is deterministic). A
claim-lattice parser that does sentence/clause segmentation (split on
'. ', ';', subordinating conjunctions, inline enumerations) + joins
wrapped bullets lifts the rate toward 1.0 → positive γ·Δ5f for that
child fork.
make bench-5f-formulate-hard runs it (|| true past the runner's
nonzero-on-failures exit). Not in `make bench-5f` / `runner --all`.
tests/test_bench_batteries.py — test_5f_formulate_hard_pack_below_ceiling
(pins rate 4/12, source=live, the 8 fails are claim-count
mis-segments).
#000046 → "Phase 1 + Phase 2 landed"; two below-ceiling 5F subs now
exist (falsification, formulate). Closure still pending an actual
surface improvement (verify_quotes tightening — bench-gated — or
parse_pointer_claims segmentation) that lifts a rate. §5 + §6 +
TICKETS.md row updated.
(Makefile also carries an uncommitted chain-check-SQL improvement
from the concurrent #000039 session — NOT included in this commit;
staged only the bench-5f-formulate-hard hunk + the .PHONY line.)
