"""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.
