Cognitive capability: extend bounded grammar to admit acquisition/action
verbs (buys, bought, collected, saved, saved-up, makes, sells) as
operation-kind entries, and pure-possession verbs (had, started, started-with)
as initial-possession anchors.
What invariant proves correctness:
- wrong == 0 across all G1 curated cases (20/20) and GSM8K probe (0 wrong/50).
- versor_condition and field invariants untouched — no algebra-path changes.
- Round-trip filter (math_roundtrip.roundtrip_admissible) unchanged.
Which CLI suite / eval proves the lane:
pytest tests/test_adr_0131_G1_verb_classes.py — 15/15 pass
pytest tests/test_adr_0126_runner_wiring.py — 9/9 pass (3 regressions fixed)
pytest tests/test_adr_0131_{1,3}_*lane.py — 17/17 pass
pytest tests/test_adr_0131_G_gsm8k_coverage_probe.py — 8/8 pass
pytest tests/test_gsm8k_math_runner.py — 11/11 pass
Key architectural change:
Acquisition verbs that also appear in ADD_VERBS/SUBTRACT_VERBS were
previously listed in _INITIAL_HAS_RE, causing branch-disagreement refusals
when a canonical 'has' initial preceded an acquisition sentence for the
same entity. Fix: narrow _INITIAL_HAS_RE to pure-possession anchors only
(has/have/had/started); acquisition verbs remain exclusively in KIND_TO_VERBS.
The solver's default-from-zero means 'Sam buys 5 apples. How many does
Sam have?' resolves as 0+5=5 without any initial-possession candidate.
Optional verb particle (up/down/out/...) added to _op_pattern to handle
'saved up N', 'picked up N' etc.
No changes to binding graph, solver, verifier, or versor/CGA algebra.
No stochastic generation, approximate recall, or hidden normalization.
Trust boundaries unaffected — no new dynamic imports or user-input paths.
