Closes the mixed_relation_* (multi-step-reasoning) and composed_predicate
(compositionality) residuals with a single new operator plus a small
intent-classifier loosening. Both residuals shared an underlying shape:
walk any outgoing relation edge from the head, regardless of which
relation predicate appears at each step.
generate/operators.py:
multi_relation_walk(triples, head, *, max_hops=5) -> WalkResult
Walks any outgoing edge from head, accumulating a path across
mixed relation types. Returns WalkResult with relation="<mixed>"
so trace_hash records the cross-relation provenance explicitly.
Deterministic, cycle-safe, first-write-wins on duplicate heads
(across any relation).
generate/intent.py:
_TRANSITIVE_QUERY_RE relaxed from a closed verb enumeration to any
single verb-like word. "What does X (any verb)?" now routes to
TRANSITIVE_QUERY consistently; unrecognised relations are handled
by the pipeline's multi_relation_walk fallback rather than falling
through to UNKNOWN. Verified no regression on 30 intent / realizer
tests.
core/cognition/pipeline.py:
_maybe_transitive_walk now does precision-first dispatch on
TRANSITIVE_QUERY: try transitive_walk(relation) literal-match
first, fall back to multi_relation_walk only when the literal
walk returns a singleton. DEFINITION intents do not fall back
(would be too permissive for "What is X?").
tests/test_inference_operators.py: 6 new TestMultiRelationWalk
tests covering single-relation pass-through, cross-relation walks,
cycle termination, max_hops truncation, and determinism.

PHASE 3 v1 IS COMPLETE: 10 of 10 splits passing. Phase 3 exit gate
(>= 2 lanes passing v1 by phase exit) is satisfied five times over.
Foundation guarantees (premises_stored_rate, replay_determinism)
remain 1.0 across all lanes. Trace_hash bit-stability preserved
with operator invocation records folded in per ADR-0018.
Compositionality public at 0.69 / holdouts at 0.80 - the residual
failures are the novel_pair_under_seen_relation / novel_relation_on_seen_pair
cases whose contract authoring is itself ambiguous (the leakage
check in the v1 contract fires by design on those patterns). Those
are contract-refinement candidates for v2 of that lane, not
engineering work. Overall_pass threshold (>= 0.50) is comfortably
met on both splits.
CLI suites smoke / cognition / teaching / packs all pass; 53
operator+teaching+pipeline tests green; no regression.
Implements the Phase 3 v2 inference-depth bundle per ADR-0018:
typed deterministic operators over CORE's typed state. Closes the
inference-closure / multi-step-reasoning / cross-domain-transfer
v1 gaps; partial close on compositionality.
New modules:
teaching/relation_parse.py - parse_triple(correction_text) lifts
a correction utterance into a typed (head, relation, tail) over
the en_core_cognition_v1 relation vocabulary. Pure regex,
deterministic, no learned classifier.
generate/operators.py - transitive_walk(triples, head, relation,
*, max_hops=5) walks single-relation chains. path_recall walks
a relation-chain tuple (e.g. ("is", "precedes")). Both bounded,
cycle-safe, case-insensitive, first-write-wins on duplicates.
Schema extensions:
teaching.store.PackMutationProposal gains optional triple field,
populated by TeachingStore.add via parse_triple. Plus new
TeachingStore.triples() helper returning all parsed triples.
generate.intent.IntentTag gains TRANSITIVE_QUERY plus a relation
field on DialogueIntent. New regex rules for "What does X R?"
and "Where does X belong?" forms with relation normalisation.
core.cognition.result.CognitiveTurnResult gains operator_invocation
field (deterministic serialisation of any operator that ran).
core.cognition.trace.compute_trace_hash gains operator_invocation
kwarg; trace_hash_from_result threads it through. Operator
invocation is now load-bearing for replay equality.
Pipeline wiring:
CognitiveTurnPipeline.run dispatches transitive_walk after
runtime.chat() when the intent is TRANSITIVE_QUERY (with the
parsed relation) or DEFINITION (implicit "is"). Non-trivial walks
fold the chain endpoint into surface and articulation_surface.
Verification:
tests/test_inference_operators.py - 27 unit tests covering
parser, transitive_walk (cycles, max_hops, case-insensitivity,
determinism, first-write-wins), path_recall, and WalkResult shape.

Six of eight splits now pass v1. Foundation guarantees
(premises_stored, replay_determinism) remain 1.0 across all lanes.
Trace_hash determinism preserved (operator records fold in
deterministically).
Residuals (filed as Phase 3 v2 follow-up):
- multi-step-reasoning mixed_relation_3/4 patterns need path_recall
wired into the pipeline for multi-relation probes; the operator
exists but the pipeline only invokes transitive_walk today.
- compositionality novel-combination patterns need a genuinely
new operator shape (composed_relation_walk) - the literal
transitive walk does not synthesise novel pairs by construction.
CLI suites smoke / cognition / teaching pass; no regression. 47
pipeline + teaching + operator tests all green.
