Adds second mandatory hazard test to VE-A/B acceptance criteria:
multi-actor pronoun ambiguity must trigger no_antecedent_ambiguous
refusal per ADR-0174 Phase 3a defense.
Verb expansion widens the cases that reach Phase 3a lookback wiring;
without this test the multi-actor wrong=0 hazard could fire silently
in production. Surfaced by 2026-05-28 Phase 1-3a lookback review.

Operationalises the recommendation from PHASE-3.1-FOLLOWUP-RECOGNIZER-EXPANSION.md
into three independent dispatchable PRs:
- VE-A: acquisition widening (gain, earn, save, accumulate, acquire) — Opus
- VE-B: new depletion class (donate, give, lose, spend, eat) — Opus
- VE-C: refusal evidence for non-arithmetic verbs (instrumentation only) — Sonnet
Each PR includes:
- Hazard pinning: explicit case 0050 test must pass after widening
- Lift evidence: at least one train_sample case moves refused → correct
- Phase 3a substrate fires: the lifted case shows a 'lookback' trace event
- wrong=0 preserved across train_sample AND case 0050
Operator decisions needed before dispatch: which specific lemmas to
admit per class, whether to introduce the depletion class at all, and
whether to ship VE-C as evidence groundwork.
Verb classification rationale per lemma documented in the brief.
Hazard surfaces called out per lemma (delta-of-attribute for 'gained',
direction inversion for 'lost', monetary-vs-time ambiguity for 'saved').
No timelines; operator dispatches when ready.
