feat(GSM8K): comprehension reading → first metric move 3/47/0 → 4/46/0 (#488)
* feat(adr-0189): comparative reading — anchor-verb widening + multi-word units

The candidate-graph comparative extractor (ADR-0131.G.2) read only has/have +
single-word units, so real-GSM8K comparatives ('Brooke does three times as many
jumping jacks as Sidney') didn't parse — a dark statement in 17 places blocking
15 of the 47 refused train_sample cases, despite the ADR-0123 solver already
supporting compare_additive/compare_multiplicative.

Widens the anchor-verb set (reusing legacy vetted lemmas + does/collected/
gained/studied…), EXCLUDING polarity-inverting verbs (lose/spend/give/sell/win)
to preserve wrong=0; admits 1-2 word units via the existing multi-word
_unit_grounds branch. Feeds the existing solver unchanged.

wrong=0 proven: G2_comparatives 29/29, G3 20/0, G4 32/32, train_sample 3/47/0
byte-identical; polarity-inverting verbs proven refused (failing-under-violation).
Chain composes correctly in isolation (146 -> 438). Flips 0 cases ALONE — every
comparative case needs a composing partner (aggregation / multi-word-noun
injection); this ships the component, not yet a flip.

- generate/math_candidate_parser.py: _comparison_anchor_verb widening + 1-2 word
  unit slots in the two multiplicative comparative regexes.
- tests/test_adr_0131_G2a_*: 5 tests incl. polarity-inversion wrong=0 guards.
- docs/decisions/ADR-0189: gap, change, wrong=0 evidence, honest scope.

* feat(adr-0189a): first metric move 3/47/0 -> 4/46/0 (case 0024, comprehension-composed)

Case 0024 now SOLVES (answer 438) by composing three general comprehension
capabilities feeding the unchanged ADR-0123 solver:
  1. day-of-week count enumeration: Sidney = 20+36+40+50 = 146
     (_day_enumeration_candidates; derived sum grounds via first count token,
      mirroring _embedded_quantifier; closed to the 7 day names)
  2. comparative reading (ADR-0189): Brooke = 3 x Sidney
  3. activity question 'How many <unit> did <Entity> <verb>?' (_Q_DID_RE)
Plus do/does/did added to the CandidateInitial anchor whitelist (production-
possession), admitted only via the closed day-enumeration shape.

wrong=0 PROVEN across every lane: all 8 capability axes wrong=0 (G2_comparatives
29/29, G3 20/0, G4 32/32, G5/S1/S3/S4 all pass), train_sample 4/46/0 wrong=0,
verify_lane_shas exit 0 (no pinned lane changed), generate_claims --check OK.
872 tests pass; new tests are failing-under-violation incl. wrong=0 guards
(non-day comma list not summed; polarity-inverting comparative verbs refused).

Re-baselined report.json + train_sample_coverage_report.json (latter also clears
pre-existing reason drift) + CLAIMS.md to the new 4/46/0 metric. Decode-not-guess:
0024 solved by READING its structure, not storing an answer. Remaining pre-existing
failures (G3 committed-report, telemetry) unrelated, fail on pristine main.

- generate/math_candidate_parser.py: day-enum extractor + _Q_DID_RE + does-anchor.
- tests/test_adr_0189a_day_enum_activity.py: 5 tests (incl. end-to-end 0024=438).
- docs/decisions/ADR-0189a + report.json/coverage/CLAIMS re-baseline.
