From 346c35ddeafc270a67127f0c439594a0a3fe60d4 Mon Sep 17 00:00:00 2001 From: Shay Date: Tue, 16 Jun 2026 14:58:27 -0700 Subject: [PATCH] test(determine): cover relational transitive CLOSE consolidation - extend with rel_pack + _tell_rel/_ask_rel/_rel_facts helpers using comprehend_relational for strict-order facts - positives: less_than(a,b)+less_than(b,c) -> consolidate less_than(a,c); before_event same; greater/after covered - derived record shape: .derived=True, epistemic_status="speculative", derivation.rule="transitive", .verdict="entailed", premise_structure_keys from verified grounds - direct recall (_rel_facts sees it) + determine() answers directly post-consolidate - multi-hop climb: p(a,b) p(b,c) p(c,d); tick1 adds a-c/b-d; tick2 adds a-d; fixed point no-op - negatives/wrong=0: parent_of/sibling_of/left_of chains refused (no derive, Undetermined); inverse mix (less+greater) does not leak; TRANSITIVE_PREDICATES set pinned to exactly the four declared; member/member fallacy test untouched - existing is-a (member/subset) and idle_tick tests remain green TDD: tests added first (RED observed), impl followed to GREEN. Targeted consolidation/relational/invariants pass. --- tests/test_determination_consolidation.py | 160 ++++++++++++++++++++++ 1 file changed, 160 insertions(+) diff --git a/tests/test_determination_consolidation.py b/tests/test_determination_consolidation.py index 252c5281..a225e948 100644 --- a/tests/test_determination_consolidation.py +++ b/tests/test_determination_consolidation.py @@ -22,6 +22,11 @@ from core.config import DEFAULT_CONFIG from generate.determine import Determined, Undetermined, consolidate_once, determine from generate.determine.determine import _verify_subsumption from generate.meaning_graph.reader import comprehend +from generate.meaning_graph.relational import ( + TRANSITIVE_PREDICATES, + comprehend_relational, + load_relational_pack_lemmas, +) from generate.realize import Realized, realize_comprehension, realize_derived, recall_realized from session.context import SessionContext @@ -51,6 +56,23 @@ def _members(ctx: SessionContext, subject: str) -> set[str]: return {f.relation_arguments[1] for f in recall_realized(ctx, subject=subject, predicate="member")} +@pytest.fixture(scope="module") +def rel_pack(): + return load_relational_pack_lemmas() + + +def _tell_rel(text: str, ctx: SessionContext, pack) -> None: + realize_comprehension(comprehend_relational(text, pack), ctx) + + +def _ask_rel(text: str, ctx: SessionContext, pack): + return determine(comprehend_relational(text, pack), ctx) + + +def _rel_facts(ctx: SessionContext, predicate: str, subject: str) -> set[str]: + return {f.relation_arguments[1] for f in recall_realized(ctx, subject=subject, predicate=predicate)} + + # --------------------------------------------------------------------------- # # realize_derived — the consolidated record # --------------------------------------------------------------------------- # @@ -247,3 +269,141 @@ def test_consolidated_facts_persist_across_reboot(tmp_path: Path) -> None: r for r in recall_realized(rt2._context, subject="socrates", predicate="member") if r.derived ] assert derived and all(r.derivation is not None and r.derivation.verdict == "entailed" for r in derived) + + +# --------------------------------------------------------------------------- # +# relational transitive CLOSE (PR-1) +# --------------------------------------------------------------------------- # +# CLOSE now consolidates sound derived facts for declared TRANSITIVE_PREDICATES +# (less_than, greater_than, before_event, after_event) using the Phase-C +# _relational_transitive verifier (search + proof_chain ROBDD).
