"""Yardstick for CLOSE derived climb (PR-3 after #788+#789). Deterministic proof that: - is-a + relational-transitive derived facts enlarge the directly-answerable set monotonically to fixed point across idle_tick (with consolidate_determinations=True). - wrong_total == 0: excluded predicates (parent_of etc.) and member∨member canary never derive; negatives remain Undetermined. - proposal candidates (derived_close_proposals_emitted > 0) appear only when review_derived_close_proposals=True. - All trajectories/replays stable (no clock/LLM). Uses real comprehend/realize/idle_tick path. Small fixed scenarios for is-a, less_than, before_event, negatives. Proposal flag checked explicitly. Replay checksum: sha256 of sorted trajectory sizes + proposal counts + closure sets.
